"Brother, you're back." Xiong Junjun walked out of the kitchen. Today was the weekend. She had not gone out at home. Seeing Li Yis beside Pang Xiaonan, she was stunned for a moment. Yes, which girl wouldn't be moved by the chic Li Yis?

But in just a moment, Xiong Junjun returned to normal and asked Pang Xiaonan: "Brother, who is this?"

"Oh, this is my classmate. I'll have dinner here tonight. How many dishes should you add." After that, Pang Xiaonan pulled Li Yis to the second floor and came to the terrace.

"Where are you practicing qigong?" Li Yis looked at the elegant environment on the terrace, a little surprised.

"This is where I meditate." Pang Xiaonan did not hide it and turned around and walked into the room. "You can wait here for a while, I'll go get something."

Pang Xiaonan took out seven spirit stones from the bedroom and returned to the terrace. The spirit stones were held on a dining plate, which was convenient for Pang Xiaonan to carry.

Li Yis looked at Pang Xiaonan who came over with a few stones, curiously took a spirit stone and asked Pang Xiaonan, "What is this?" After saying that, he stared at the spirit stone and looked carefully. He felt a strange feeling coming from the spirit stone in his hand.

"This is a rare substance. I call it a spirit stone. I can absorb some energy in this environment through it to improve some of my cultivation, such as internal strength." Pang Xiaonan sat on the sofa facing the sea, and asked Li Yisi to sit over and continue, "Do you Dongyue Sect have similar skills?"

Li Yis nodded and said, "If we practice internal skills, it is not much different from ordinary sects. The energy sinks into the dantian and runs through the large and small circles. Try to control the flow of breath in the body. The more you control it, the higher your internal skills are."

Pang Xiaonan smacked his lips and said, "Well, this is the most basic method of internal strength cultivation. Then I can tell you that using these spirit stones will greatly speed up your internal strength cultivation."

Originally, Pang Xiaonan wanted to hand over Li Yisi some ways to absorb spiritual power, but for humans who had never been exposed to sucking spiritual power, his method may not be effective, so he thought of another way, which was to let Li Yisi use the spirit stone to absorb spiritual power in the air first, and then slowly experience the skills of sucking spiritual power, and then remove the spirit stone. At this time, Li Yisi can also rely on himself to absorb spiritual power according to his previous experience.

"Oh? Is it? Then please teach me quickly." Li Yis was very interested in the skills of speeding up the practice that Pang Xiaonan said, and he was eager to get started immediately.

Pang Xiaonan left the sofa with his spirit stones and built a seven-star spirit stone array on the terrace. He introduced to Li Yisi: "This is a formation that absorbs spiritual power in the air. I call it the seven-star spirit stone array. Come, sit in the eyes of this formation."

Pang Xiaonan pointed to a position, Li Yis got up and walked over, and sat down obediently.

"I'll briefly tell you the principle," Pang Xiaonan pointed to the outer stones, "The purpose of this array is to use the outer spirit stones to absorb the spiritual power in the air and then transmit it to the array eye," Pang Xiaonan pointed to the stone in front of Li Yis again, "The spirit stone in front of you is the array eye, so when you are circulating the breath in your body, you think in your mind that the stone in front of you will transmit the spiritual energy to you. Okay, now you start to enter into meditation and operate the cycle of heaven."

Li Yis said "Okay", then closed his eyes and began to adjust his breath. According to what Pang Xiaonan said, the spiritual stone in the array eye was imagining the spiritual energy continuously to himself.

At first, Li Yis felt a little difficult because it was the first time to absorb energy from the air and he couldn't find the trick. However, slowly, he fumbled for a long time and finally discovered some skills. He felt a wave of spiritual power in his body, which seemed to be transmitted from the stone in front.

Pang Xiaonan was observing the movements of the Seven-Star Spirit Stone Array. When he found that the spiritual power around him began to surge, he knew that Li Yis had begun to find the trick.

"It is worthy of being the pride of the Dongyue School, and it is so talented." Pang Xiaonan sat leisurely on the sofa facing the sea. Looking at the waves coming from the sea in the distance, he couldn't help but feel refreshed.

About half an hour later, Pang Xiaonan woke up Li Yisi who was immersed in the surging of spiritual energy, "How about you, do you feel the benefits of spiritual power?"

Li Yisi opened his eyes, and his eyes were clear, like a pool of clear water. The sucking of spiritual power made him feel more comfortable. He sighed: "It turns out that the spiritual power of nature is so intoxicating."

Li Yis stood up and said to Pang Xiaonan: "This feeling is something I have never felt in my life. That kind of pure power makes people relax the whole body, but I also feel the infinite energy contained in it. I can feel my dantian heat up, and the small universe in my body also wants to continue to expand. Your technique is really wonderful!"

Pang Xiaonan packed up the spirit stones on the ground, put them one by one on the dining plate, and said, "You have already touched the way to absorb spiritual power for the first time. It's not simple, and the future is limitless."

Li Yis helped Pang Xiaonan put the spirit stone on the plate and said with a smile: "You gave me this future. Thank you, thank you for teaching me such a mysterious martial art. However, if I need to practice in the future, do I have to come to you?"

Li Yis thought that this spirit stone was so expensive, Pang Xiaonan might not lend it to him.

Pang Xiaonan packed up the spirit stones and said to Li Yis: "That's right, you must come to me to practice in the early stage, because this formation cannot be placed anywhere. Besides, the environment here is indeed rich in spiritual power. Even if you use my spirit stone to find a place to set up a seven-star spirit stone array in the school, the effect will not be better. Look, there is a sea in front and a mountain behind. This place can be said to be a gathering of spiritual energy from heaven and earth. But you don't have to worry. Once you successfully control the use of spirit stones to absorb spiritual power, you can slowly remove the spirit stones and use your own abilities to absorb spiritual power."

"You mean, you can absorb the spiritual power in the air without the help of spirit stones?" Li Yis looked at Pang Xiaonan with a gaze. If this is the case, then he can absorb the spiritual power in the air anytime and anywhere.

"Yes," Pang Xiaonan nodded, "I can absorb energy in the air without using the spirit stones, but you can't have such experience at the beginning. This is why I teach you how to use spirit stones to absorb spiritual power. Only when you truly understand the key points of absorbing spiritual power can you let go of the spirit stones and absorb spiritual power by your body alone."

"No wonder your cultivation is so high. It turns out that you have learned to absorb the energy of nature to enrich your cultivation." Li Yisi sincerely admired Pang Xiaonan's skills. No one has ever told him that he can also use the power of nature to enhance his strength. Everyone knows that pursuing the unity of man and nature, but no one can create a simple method to reach that level. Today, Pang Xiaonan actually gave it to others, which made people not moved.

"It is not enough to absorb spiritual power alone," Pang Xiaonan held the dining plate and walked into the room. "Let's go, let's have a meal first, just like if you only eat and don't exercise your body, your muscles will not be developed, your strength will not increase, and the same is true for absorbing spiritual power. I must use it, so I let you join the Black Mamba and have the opportunity to exercise your martial arts. In this way, we can better improve our technical and tactical level by absorbing spiritual power."

"You said it right, then I'll be with you from now on," Li Yis and Pang Xiaonan have been together for a long time and no longer acts kindly. "But I'll disturb you too much when I come here every day?"

"Don't disturb you, you can come here every day at noon or at night," Pang Xiaonan put the spirit stone into the bedroom, closed the bedroom door and turned around and said to Li Yis, "When the time comes, I will put your fingerprint into the smart lock on the door, and you can come in directly."

"This... isn't that good? Are you not worried that I will steal your things?" Li Yis frowned. The master was not at home and he had lost something when he entered someone else's house.

"Look at you, the great disciple of the Dongyue Sect, will you still steal other people's things?" Pang Xiaonan hugged Li Yis' shoulders, "Don't think too much, you and I are people who are about to go to the battlefield. In the future, I will have a life-long friendship. I am not afraid that you will come back safely. Moreover, if I lose anything here, you can afford it, haha."

The reason why Pang Xiaonan asked Li Yisi to come to the evening or at noon was mainly because he had an appointment with Zhao Sijiajia in the morning. It is easy to say that the two of them practiced martial arts together, but the three of them had some fights together.

The food was ready and all were placed on the dining table. Xiong Junjun sat on the sofa watching TV. Pang Xiaonan shouted to her: "Little sister, we're here to have a meal."

Xiong Junjun heard the sound and walked to the dining table and sat down, and said to Pang Xiaonan: "Brother, is the food a little cold? Do you want to heat it up?"

"No," Pang Xiaonan picked up a piece of braised pork with chopsticks and tried it, "Well, it's not bad, it tastes good, the temperature is neither hot nor cold, just right."

Seeing that Li Yis was still standing, Pang Xiaonan hurriedly greeted: "Sit down, don't be polite, think it's your own home. Let me introduce you to me, this is my sister, cousin, Xiong Junjun, who lives here with me during holidays. These are all dishes she cooks. Her skills are good, come and try it."

Li Yis smiled gracefully at Xiong Junjun and said, "It's time for my sister Xiong Junjun."

Xiong Junjun smiled embarrassedly and said, "It's nothing. Since I'm my classmate, I'm a guest. The food is not tasty, so please forgive me. I will make a few home-cooked dishes."

Li Yis sat down and explained with a smile: "Pang Xiaonan and I are classmates, brothers, and not guests. Don't be restrained. Sit down, let's move!" After that, he picked up the chopsticks and started to braised pork without hesitation.

The next morning, the genius was slightly bright, and Pang Xiaonan stood up from the terrace. He had been sucking spiritual energy here for half an hour, and now he was almost full.

Pang Xiaonan packed up the spirit stones and suddenly had an idea in his mind, "Can the spirit stone array be automatically activated? That way, the spiritual power in the air can be input into other items."

Thinking of this, Pang Xiaonan couldn't help but look at the things around him, "What should I input the spiritual energy into?"

A wave on the sea surface hit and slapped on the beach, stirring up Pang Xiaonan's thoughts, "By the way, input it into the water to see if there has been any changes in the water."

So Pang Xiaonan turned around and went downstairs, found a bottle of mineral water in the refrigerator, then took a white porcelain bowl from the cupboard, poured the mineral water into the white porcelain bowl, and took the bowl of water upstairs.

Pang Xiaonan put the bowl aside, arranged the Seven-Star Spirit Stone Array again, and then put the bowl in the eyes of the formation.

The bowl was there, but there was no fluctuation in the Seven-Star Spirit Stone Array. Pang Xiaonan could not feel the surging of spiritual energy around him. "Sure enough, this formation still cannot operate by itself."

Pang Xiaonan sat next to the white porcelain bowl and stared at the water in the bowl and thought hard, "Is there any way to get spiritual power to enter this bowl of water?"

The waves kept beating the beach, the back waves pushed the front waves, and the sea water did not stop for a moment, and the sound came to Pang Xiaonan's ears. "Where does this tide come from the momentum like this surging?"

Pang Xiaonan pondered the physics knowledge he had learned, "It's Ye Liang's gravity! Ye Liang's gravity triggered the tide."

Hallelujah has a satellite, which people call night light, because it lights up as soon as it gets night.

In ancient times, people called the rise and fall of the sea water that occurred during the day "tide"; the rise and fall of the sea water that occurred at night "tide", collectively called "tide". Ancient ancestors had noticed that the tide was related to the bright night, so the ancient saying said: "When the waves rise, the rise and fall of the moon."

The tide-induced force at night will not only generate sea tides on Hallelujah, but also cause atmospheric tides. However, the atmospheric tide is far less earth-shaking and majestic. It is also difficult for people to detect it because they are in it. In addition, the tide-induced force will also cause tides to occur on Hallelujah, including the surface of the earth (the parts below the continent and the ocean floor). This tide is called solid tides. The solid tide causes very small ups and downs on the surface. Only with precision instruments can it be measured. This may have a subtle impact on the gravitational field of Hallelujah. Some parts of Hallelujah are liquid, so tides will also occur there. Some people believe that the tides inside Hallelujah are one of the causes of earthquakes.

"Since gravity can trigger tides, I will act as the night light to lure all the spiritual energy to form tides!" Pang Xiaonan wanted to use physical principles to introduce the spiritual energy into the bowl of water.

"What if I don't do my best here? Will the tide of spiritual energy stop?" Pang Xiaonan suddenly had new doubts.

Pang Xiaonan stood up and slowly walked to the railings of the terrace, staring at the waves that kept rushing over and slapped on the beach.

"By the way, there is still inertia! Even without gravity, the waves will still rush up the beach due to inertia!"

Inertia is an inherent property of matter and is a phenomenon of resistance. It exists in each object, and its size is proportional to the mass of the object, and it is trying to keep it in its current state, whether it is a static state or a uniform linear motion state.

When you kick the ball, the ball starts to move. At this time, because the ball itself has inertia, it will keep rolling until it is stopped by external forces. Any object has inertia at all times and it must maintain its original state of motion.

On the surface of Hallelujah, inertia is often masked by friction, air resistance and other effects, which prompts the object to move slowly and usually ends up in a static state.

After the spiritual energy is triggered by gravity, it will form inertia. Although it will eventually be prevented from moving by other substances in the air, there will definitely be a period of time in between.

"Try it and see how long the inertia can last."

Pang Xiaonan walked back to the white porcelain bowl, near the eye of the formation, and sat down.

After adjusting his breathing and entering a state of half-entering meditation, Pang Xiaonan began to perform his skills and circulated the entire Seven-Star Spirit Stone Array in his mind.

Gradually, the spiritual energy in the air began to gather towards the Seven-Star Spirit Stone Array. It was first absorbed by the six spirit stones outside, and then teleported to the spirit stones in the middle by the six spirit stones outside.

At this time, Pang Xiaonan opened his spiritual consciousness and strengthened his mind, so that the spirit stones in the array's eyes could transmit the spiritual energy transmitted from around him to the mineral water in the white porcelain bowl.

At this time, the mineral water in the white porcelain bowl had some slight waves, just like there was a spring at the bottom of the bowl, which was gurgling upwards.

The waves of mineral water are first big waves, and then the vibration frequency is getting faster and faster, changing from big waves to fine small waves. As the spiritual energy is input more and more, the density of the waves is getting bigger and bigger, but it is never boiling.

About five minutes after launching the Seven Star Spirit Stone Array, Pang Xiaonan felt that the surrounding spiritual energy had reached a stable peak. He stopped exercising his power and opened his eyes.

At this time, he saw the mineral water in the white porcelain bowl shaking densely. Some bubbles entered the water from the surface of the water, and some bubbles emerged from the inside of the water.

The bubbles alternated up and down in the mineral water, left and right, and the whole bowl of water was stirred by the bubbles, and it was very uneasy. "This is the free diffusion of spiritual energy in the water, and a chemical reaction occurred."

Pang Xiaonan stared at the bowl of mineral water, wanting to see what changes would happen to this bowl of water.

Slowly, the fluctuations in the water began to decrease, the bubbles became fewer and fewer, and the waves on the water surface gradually calmed down.

The entire water body fluctuated for about five minutes. Pang Xiaonan took out his mobile phone to time the time since he opened his eyes. He wanted to see how long the inertia of the spiritual energy lasted.

"Can you only last for 5 minutes?" Pang Xiaonan sat cross-legged on the ground, holding his chin with his hands and tilting his head to think.

"Is there any way to automatically input mineral water for a longer period of time?" Pang Xiaonan began to decompose every key link of the formation he built.

"Then we must think of ways to increase the inertia from the principle of inertia." Pang Xiaonan began to recall several determinants of inertia.

In physics, inertia is the property of an object that resists its state of motion being changed. The inertia of an object can be measured by its mass. The greater the mass, the greater the inertia.

"By the way! Increase the amount of spiritual energy can increase inertia!" Pang Xiaonan snapped his fingers. He felt that he was a genius, and he thought of such an obvious truth.

"How to increase the amount of spiritual energy?" Pang Xiaonan looked at the left, then looked again, and looked down at the bowl of water and was out of the divine state.

At this moment, the mineral water in the white porcelain bowl had calmed down, and the rising sun shone thousands of golden lights, one of which shone on the water surface.

A golden light reflected from the water surface, stinging Pang Xiaonan's eyes, "By the way, spiritual energy is attracted by several spirit stones on the outside. As long as the number of spirit stones on the outside is increased, the number of spiritual energy will increase with a pipe that transports spiritual energy!"

Pang Xiaonan moved his butt and looked at the outside of the spirit stones, "It seems that this formation has to be changed. Fortunately, I still have extra spirit stones to use, but this is a technical job."

To increase the number of spirit stones, the spirit stone arrangement of the Seven-Star Spirit Stone Array will inevitably be changed. Then you can no longer call it the Seven-Star Spirit Stone Array, it may be eighteen stars or twenty-eight stars.

Thinking of this, Pang Xiaonan frowned and patted his right hand on his forehead. "Annoyed!" The last time he placed the Seven-Star Spirit Stone Array, it took Pang Xiaonan more than half a day. If he wanted to set up another formation with more spiritual energy, he would kill many of his brain cells.

"After that being said, what effect does this spiritual energy have injected into mineral water?" Pang Xiaonan turned his gaze to the bowl of white water that absorbed a large amount of spiritual energy.
To be continued...
