After asking Xia Ningshang carefully, Yang Kai realized that it was a coincidence that she had the dusty gas.

At that time, Yang Kai immediately went to Tongxuan Continent, and Xia Ningshang was extremely lonely. In order to pass the time, he could only sit in the Nine Heavens Holy Land and refine pills for others every day.

She was originally a holy body of medicine and spiritual cultivation.

While a large amount of elixir was refined, Xia Ningshang's cultivation and his terrifying speed were increasing, and there was no bottleneck at all.

In just a few years, she had become a saint and caught up with the realm when Yang Kai left that year.

Later one day, she was bored and secretly ran out alone to travel, but ended up getting the dusty gas in a hidden underground cave.

From then on, her cultivation level was even more uncontrollable. She crossed the level of entering the holy realm in ten years and was promoted to the holy king realm. It took her more than ten years to reach the realm of the two-level realm of the holy king realm.

Yang Kai was dumbfounded when he heard this.

Such a terrifying cultivation speed is that even on the Dark Star, the disciples of major sects and major forces may not be able to do it.

However, in this barren Tongxuan Continent, the younger sister accomplished such a feat.

The reason why Xia Ningshang achieved what she has achieved today is indeed related to the inseparable dust gas.

"Where do you feel uncomfortable after you get it?" Yang Kai asked seriously.

"There is not too much discomfort." Xia Ningshang thought about it carefully, "Sometimes I suddenly feel some fatigue, and sometimes I become very lazy and don't even want to think about it. Haha, it's like I'm old."

Yang Kai nodded gently.

"Junior brother, is there any problem with it?" Xia Ningshang asked.

"I dare not determine whether it is a blessing or a disaster." Yang Kai shook his head slowly, feeling a little worried.

"What the hell is it?"

"I don't know, but I have a guess. If this guess is true... then, this is your opportunity!" Yang Kai looked at Xia Ningshang with a burning look, his expression was a little excited.

That vague guess made him excited!

"By the way, do you remember where did you get it?"

"Yeah." Xia Ningshang nodded.

"Take me to see!" Yang Kai said, reaching out to wrap Xia Ningshang's slender waist, sacrificing the star shuttle, turning into a long rainbow and disappearing into the Nine Heavens Holy Land.

Following the route guided by the senior sister, Yang Kai and her were flying in the air at a very fast speed.

In just one day, the two of them came to a mountain range that stretched for thousands of miles.

Xia Ningshang has a good memory. Even after more than twenty years, she still clearly remembers the place where the dusty gas was found that day.

Soon, the two of them arrived at a valley, and Yang Kai fled down the Star Shuttle and walked towards a certain place with Xia Ningshang.

Soon, a deep dark hole was imprinted into the eyes of the two of them. Xia Ningshang pointed to the hole and said, "Junior brother, I went in from here, and then went deep into the lowest level and got the ball of things."

"Go in and take a look." Yang Kai grinned, skilled and brave, and was not afraid at all. He took Xia Ningshang's hand and drilled into the cave.

The cave is extremely dark, the air is quiet, but it is not damp, but it is extremely dry.

As soon as You entered the cave, Yang Kai raised his eyebrows.

He felt the rich spiritual energy of heaven and earth from this cave!

Of course, this kind of richness is only compared to other parts of Tongxuan Continent, and cannot be compared with the Dark Star or other famous cultivation stars in the star field.

However, this is also rare.

Moreover, the deeper you go down, the more abundant the spiritual energy appears.

Yang Kai's expression was excited, and he suddenly realized that his guess should be almost the same, and this abnormal spiritual energy was a side view.

This is indeed an opportunity for the junior sister! If the dust gas is handled well enough, it will definitely bring unimaginable benefits to Xia Ningshang, allowing her to change from then on and turn into a cocoon into a butterfly.

The two of them held hands and went deeper step by step.

Suddenly, Yang Kai seemed to feel something and quickly stepped down.

At the same time, the young senior sister cheered: "It's here, I feel it! It's coming!"

A mysterious ball of energy was approaching from the front at an extremely fast speed. Yang Kai investigated his divine consciousness and found that the fluctuations of this energy were exactly the same as those he had pulled out of his senior sister's body a few days ago.

The gray gas escaped into the ground and indeed returned to where it was. Now that it felt the breath of Xia Ningshang, it couldn't wait to see her.

In a moment, the gray air was approaching.

It did not dare to pounce on Xia Ningshang directly, but stopped ten feet in front of Yang Kai.

It felt the threat from Yang Kai!

"Junior brother..." Xia Ningshang looked at him and asked for his opinion.

"Care it, I didn't want to scare it away that day, I just wanted to see what it was." Yang Kai opened his body sideways and gave way.

Xia Ningshang immediately called out with her mind. The gray air felt Xia Ningshang's call. She shook slightly and rushed past Yang Kai, rushed directly towards Xia Ningshang, and crawled into her body and disappeared.

Xia Ningshang's delicate body shook and she moaned.

A little golden light suddenly burst out from Yang Kai's left eye, and his narrow and majestic golden pupils appeared and stared at Xia Ningshang.

Demon Eyes of Destroying the World!

Under his peeping, after receiving the dusty gas, a gray aura that was invisible to the naked eye spread out of his body.

This kind of aura is generally only possessed by the elderly who cannot live long. Once this aura appears, it means that the person has no life span.

The young senior sister is in her prime and is shrouded in this aura. There is only one reason why she is shrouded in this aura, that is, that gray gas is at work!

Yang Kai was not surprised, as if he had expected it, and he was not in a hurry. He just waved to the senior sister and said, "Come with me!"

Xia Ningshang nodded gently and followed Yang Kai step by step.

The two continued to go deeper, not knowing how long it took or how far it had walked. Yang Kai only felt that the spiritual energy of the world around him was getting stronger and stronger. However, this rich spiritual energy did not give Yang Kai any sense of comfort, but instead felt a little sad when he returned to the scene.

When the spiritual energy of heaven and earth was almost comparable to that of the dark star, Yang Kai and Xia Ningshang suddenly came to a huge underground cave.

A faint light shining deeper in the ground ahead, as if it was conveying some message, impacting the sea of ​​consciousness of the two and summoning them to move forward.

Summoned by this, Xia Ningshang's beautiful eyes became confused and her body moved forward uncontrollably, like a moth flying into the fire, unswervingly.

Yang Kai's face darkened, and a low cry came from his mouth, and a tide of divine thoughts poured into Xia Ningshang's sea of ​​consciousness like a tide.

The youngest sister's delicate body shook and her face turned pale. After she came to her senses, the confusion in her eyes disappeared, and she replaced it with infinite horror.

"Junior brother, I..." Xia Ningshang was a little at a loss. She didn't know what was wrong with her just now. She was dominated by a force in the dark, so she couldn't think independently.

"Well. Look over there!" Yang Kai pointed in one direction.

Xia Ningshang looked at her beautiful eyes and her beautiful eyes trembled slightly.

There were dense corpses sitting upright, and everyone's body was extremely dry, and some had even weathered into ashes. However, from the traces in some corpses, it is not difficult to see that they seemed to have been drained by some force in an instant and fell here.

"Who are these people? Why are they all dead here?" Xia Ningshang leaned against Yang Kai, as if she wanted to find some sense of security.

"If I'm not mistaken, these people are the same as you."

"Like me?" Xia Ningshang frowned. She was also a kind-hearted woman. After thinking for a while, she understood: "You mean, they have all gotten that smoky gas?"

"Probably." Yang Kai smiled.

"Then why..." Xia Ningshang felt cold all over. The thrilling scene just now appeared in his mind again. If Yang Kai had not awakened him in time, his fate would have been worrying, and he might have ended up like these people.

"Because the body of that grey gas wants to be replenished by energy, it chooses you, cultivates you, and makes you stronger. The stronger you are, the better it will be."

"Why did it do this?" Xia Ningshang looked puzzled.

"It's going to die!" Yang Kai replied, suddenly shrugging his shoulders again, "These are all my guesses. You'll know if it's right?"

As she said this, Yang Kai grabbed Xia Ningshang's hand and walked forward step by step.

The white bones were stomping under my feet, and there was a crackling sound, which made people feel creepy and chill.

Yang Kai narrowed his eyes and looked at the faint light ahead.

Soon, the two of them arrived at the place where the light came.

This is the edge of the underground abyss, and it is a little deeper below, but when you look out, you can suddenly find that under the abyss, there is a gray light burning like a huge light.

The light was extremely dim, and the color was exactly the same as the gray gas that Xia Ningshang got.

"Sure!" Yang Kai took a deep breath. After seeing the huge gray light as light, he immediately affirmed his previous guesses.

"Junior brother, what is this?" Xia Ningshang looked at the ash fire suspiciously, and vaguely felt that the gray gas in his body had a close relationship with it, as if it was separated from the ash fire, and the two were one existence.

"The Origin of Stars!" Yang Kai whispered, his expression suddenly became extremely excited.

"The origin of the stars?" Xia Ningshang was extremely confused.
