Hearing him say this, Luan Baifeng reached out and grabbed a black stone the size of a washbasin in her hand, threw it to Yang Kai and said, "You can try it yourself, I can't confirm it anyway."

Yang Kai took the black stone and weighed it in his hand. He found that the weight was really not light. He pinched it a little hard, and there was no trace left on the black stone.

You should know that he is now extremely powerful. Even if he pinched the mineral like this, it would at least crack if it was crushed. However, the black stone obviously has an extraordinary texture and is extremely strong.

The divine thoughts surged, and Yang Kai wanted to investigate the situation inside the black stone. However, under his perception, the black stone in his hand completely isolated his divine thoughts, and he could not find out whether there was anything hidden inside.

Yang Kai exclaimed in surprise. He is now the sixth-grade Kaitian, and his divine consciousness is powerful, and he is still isolated by this black stone. What is this black stone...?

After a moment of pondering, Yang Kai activated the Demon Eye of the World, and his left eye immediately turned into a golden vertical cord.

Looking around, he could see something different. There was a vague and vague light yellow energy surge inside the black stone in his hand.

This scene made Yang Kai feel happy, and the Demon Eye of Destroying the World is useful!

Although he could not see the specific situation inside the black stone, what was certain was that there was something in the black stone in his hand, and it should be a earth-based thing. As for what grade it was, there was no way to judge it. He had to dissolve the black stone.

The Demon Eye of the World Destroying World has the ability to break the illusion, and is known as the two unspeakable secrets of the Ten Thousand Demon Heaven together with the Purgatory Black Eye. They are extremely profound pupil techniques. Even in the Ten Thousand Demon Heaven, only the most core disciple is qualified to practice.

His devil eyes of the world-destroying demon were obtained when he was very weak back then. Before he met Ti Zheng, Yang Kai didn't know these secrets.

However, since it is the two unspeakable secrets of the Ten Thousand Demon Heaven, the Demon Eye of the World Destroying Demon has its own mystery. The divine mind cannot sense the situation inside the Black Stone. The Demon Eye of the World Destroying Demon Eye can break through some illusions and penetrate the essence of it.

However, Yang Kai, who practiced the Demon Eye of the World, could not practice it, so he could only look at it in a vague way. If the person who practiced the secret technique of Wanmotian was really investigated, I think he could see it more clearly.

His actions were not hidden from Luan Baifeng. At this time, the woman looked at him in surprise: "You actually practice the pupil technique?"

"What?" Yang Kai took away the Demon Eye of the Destroying World and turned his head to look at her.

Luan Baifeng slowly shook her head: "Nothing, but what tricks do you see?"

"No." Yang Kai replied casually. Although Luan Baifeng saw that he had an eye technique, he should not recognize that it was Wan Motian's secret technique. Yang Kai would not explain anything to her.

However, in order to verify the information he had just investigated, Yang Kai immediately activated his own world power and wrapped the black stone in his hand.

The black stone shrank rapidly.

His sixth-grade Kaitian cultivation level, and his world power is much more powerful than that of ordinary sixth-grade, so the speed of dissolving black stone is naturally extremely fast.

The basin-sized black stone in my hand disappeared completely in just one stick of incense, and a piece of earth-yellow crystal slowly appeared.

Luan Baifeng looked in surprise: "Fourth-grade earth travel, you are lucky!"

Yang Kai threw away the yellow crystal stone casually and said, "What is the probability of the black stone containing the cultivation materials?"

"It's rare." Luan Baifeng replied softly, "When you are lucky, you will be about 30%. If you are lucky, you may not even have 10%."

"Thirty percent is too low." Yang Kai shook his head slowly. There were seven of the ten black stones without anything. How much time and manpower would it take to waste?

"That's why I said that every piece of practice in the black prison is hard-won. Do you think this place is full of treasures, and you can just bend over and pick them up?" Luan Baifeng sneered, paused, and frowned and said, "What are you looking for? I have already earned all my black prisons for so many years. Isn't it enough?"

Yang Kai shook his head slowly: "Not enough, I still need more things that are sixth-grade Yin and Yang."

Luan Baifeng frowned and said, "If you use your own practice, you can refine the resources of the fifth grade. Although the speed is slower, the fifth grade is not that difficult to find. Why should you be stubborn on the sixth grade?"

She obviously thought that Yang Kai had to refine and practice for so many sixth grade resources.

Yang Kai smiled and said, "You can naturally use the fifth grade for your own practice, but what if someone needs to be promoted to the sixth grade for Kaitian?"

Luan Baifeng was stunned for a moment, then widened her eyes: "How is it possible? How can so many people in your void have advanced to the sixth rank?"

You should know that everyone who can directly advance to the sixth grade has hope to impact the eighth grade Kaitian, and the number is extremely rare. Even if it is placed in those lucky places in the cave, it is a once-in-a-thousand-year genius. Yang Kai has previously searched for a lot of yin and yang geniuses of the sixth grade from him, which is enough to meet the promotion needs of ten people, but it is not enough?

Yang Kai did not explain and said it was useless. Now Luan Baifeng has returned to her command. When she turned around and saw the foundation of the void, she naturally realized that she was not swearing.

"Don't stand, help me, dissolve these black stones first to see if I can find what I need." Yang Kai greeted. Although there were more than a dozen Kaitian Realm busy, their efficiency was not high. The higher the cultivation level of dissolving black stones, the faster the speed, it should be related to the majesty of the world's great power.

Luan Baifeng looked at him in surprise, obviously still shocked by what he said just now. Hearing this, "The black stone here should not be of the sixth grade, so don't be busy."

"Huh?" Yang Kai turned his head to look at her: "Why do you say that?"

Luan Baifeng stroked a long strand of hair on her chest: "I have been with the Black Domain for so many years, and I have some experience. There are countless mineral stars in the Black Domain. The deeper the mineral stars, the greater the chance of producing high-quality materials. Now the harvest is basically based on the mining of the outer mineral stars. It would be good to have a maximum of five grades. If you don't believe it, you can see it yourself."

Yang Kai actually noticed that the resources that Luan Baifeng’s more than a dozen men produced from the black stone were indeed only the fifth grade, and there were not many. He couldn’t help but frown slightly: “Where did you get those sixth grade or even seventh grade?”

Luan Baifeng said: "Of course, it is a deeper mineral star. In the past, I had several sixth-grade mine slaves under my command. They mined those things. Unfortunately, since they died, no one has been able to penetrate those mineral stars, so naturally I can't get them again."

Yang Kailairan: "So when the Tianjian Alliance made things difficult for me in the void before, you went to intervene with great enthusiasm?"

Luan Baifeng didn't comment.

Yang Kai touched his chin: "In other words, if you want to get the resources of the sixth grade, you have to go deep into the black domain to mine."

"So that's it!"

Yang Kai nodded: "Since that's the case, let's go."

"What?" Luan Baifeng looked at him in shock, almost thinking that she had heard it wrong, "What are you going to do?"

"Go to the mine star that can produce sixth grade resources and mine black stones!" Yang Kai said, reaching out to grab Luan Baifeng, grabbing her shoulder, turning his head and leaving.

Luan Baifeng was angry and anxious: "Let me go, I won't go!"

Yang Kai laughed: "Since you have joined my command, you can't help it."

"You bastard!"

A dozen busy Kaitian Realm watched in a daze as their warden flew away like a chicken by Yang Kaili. They cursed all the way, and disappeared in a flash. They all felt like ghosts, and their foreheads were sweating coldly.

In the void, Yang Kai activated the power of the world to rush around Luan Baifeng. The latter clearly looked uncooperative and his face was as cold as ice.

"Why do you look like your parents are dead? You are just going to mining, not taking your life!" Yang Kai laughed.

Luan Baifeng said coldly: "That's because you don't know the danger deep in the Black Domain. Even if I have been operating here for so many years, I dare not say that I know everything about the Black Domain. There are countless ban formations here. Once touched, you and I will never escape death!"

Yang Kai nodded and said, "So I have to rely on you all the way. I am not proficient in the battle. If I die here, you will not have a good end."

Luan Baifeng gritted her teeth: "I have never seen someone as shameless as you!" She secretly regretted it. If she had known this, why would she have told Yang Kai that the deeper mineral stars had the sixth grade resources? This time she actually shot herself in the foot.

However, although this woman's words are not nice, she is quite conscious of the current affairs. Otherwise, she would not surrender easily before. She knew that she would not resist, so she became obediently after playing a tantrum for a while and then started working together.

She also knew that if she was lazy and unable to do her best this trip, Yang Kai would run around in the black domain like this, and it would only be a matter of time before she could touch the forbidden formation, and she would suffer.

Walking along the way, after half a day, Luan Baifeng suddenly said, "I have arrived at a relatively dangerous area. Don't be too far away from me, otherwise I will be involved in the formation and I will not be able to save you!"

"I know!" Yang Kai nodded continuously.

At this moment, Luan Baifeng suddenly pointed and touched her eyes. Yang Kai turned his head and looked at her eyes and saw that purple fluorescent suddenly bloomed, giving people a very charming feeling.

Yang Kai raised his eyebrows and realized that this woman also practiced the pupil technique, so she said that when she used the Demon Eye of the World Destruction.

It should have been the gaze of Yang Kai that he noticed. Luan Baifeng explained: "My pupil technique is born with it, not acquired cultivation. Although its power is not strong, it seems to have a natural advantage over breaking the formation."

Yang Kai suddenly realized: "This is how your formation attainments come from?"

Luan Baifeng's pupil technique is born with great advantages in breaking the formation. She has been tired and living in this black prison all year round. Observing the changes in the formation restrictions here, even if she doesn't understand the formation, she is enough to grow into a master.

Luan Baifeng snorted coldly: "Or what would you think a lonely little girl would struggle to survive in these three thousand worlds?"

"Little girl!" Yang Kai couldn't help but sneer.
