Wang You's eyes were closed, and a violent aura filled every inch of his meridians. With the experience of the last time, Wang You calmed down and tried his best to absorb it. The aura is absorbing, and the meridians are still expanding, but there is no longer the first speed, but steadily expanding outward.

After absorbing most of the aura, a large amount of auras began to gather in Wang You's dantian, gathering more and more, gradually forming a space. And after the aura fills this space, it does not stop, and it is still gathering endlessly into the space. Eventually, due to the pressure, the aura began to turn from a gas to a liquid. One drop, two drops, three drops, five drops. The ichor continued to gather in the space until it occupied a third of the entire space.

"Is this the foundation realm? this is... A sea of air?"

After Wang You's cultivation was completed, Xuanyu also jumped out and taught Wang You a necessary skill for cultivation: internal vision.

Inner vision, as the name suggests, allows you to observe everything in your body.

For cultivators, the most they can do is to cultivate and fight, and both of them may cause varying degrees of damage to the body.

And if the secret injury cannot be treated in time, it is likely to accumulate into a lot, which will eventually lead to a madness during cultivation, and even affect the mobilization of aura during battle, so that it will not be able to exert its combat power.

"The sea of qi has filled one-third, and my realm has also reached the peak of the early stage of foundation building. But... Why didn't the system move this time? And it feels... Why does this feel so strange? Obviously you have already made the cut, why do you feel so depressed?"

"it!Wang You! Go to the suburbs! Go to a place where there is no one!" Xuanyu suddenly appeared in front of Wang You again.

"Why? I'm feeling a little sick... I want to take a break..."

"Slow down! Hurry up! Go to the suburbs immediately! The farther away the better! It's better to go deep in the mountains and old forests!"

"Okay, okay..."Wang You had never seen Xuanyu so anxious, as if... What a powerful and irresistible enemy is faced.

Wang You walked out of the system space and saw that the house was in a mess again, exactly the same as last time. He kind of understood, this situation, I'm afraid it wasn't made by himself... Glancing at the messy bedroom, Wang You opened the door and went straight to the suburbs.

"Not enough, not enough, not enough here!Go again!Go to the front!In the ravine ahead!" Xuanyu's anxious voice kept ringing in Wang You's ears.

Today's Wang You's speed is no longer comparable to ordinary people, but he can't exert the fastest speed, the faster the speed, the more breath is released, and the more obvious the depressed feeling.

"Alright, here it is. After Wang You had gone hundreds of miles, Xuanyu told Wang You to stop.

"And then? What's wrong with me? You didn't tell me, you kept telling me to run, and now I don't know where it is. Wang You had a question mark in his head, but he quickly thought of something.

Wang You raised his head and looked at the sky: "I'm Nima, won't you?" Wang You's eyes were about to pop out.

"That's what I thought just now. Xuanyu in the system space nodded helplessly.

"But, I've only built the foundation!"

"Maybe it's due to the incomplete rules of the earth..."

If the monks on the earth knew about this, I am afraid that they would not spit on Xuanyu one by one, and curse "Fart!" in their mouths!

"Then what should I do now?" Wang You experienced this kind of thing for the first time, and he was obviously a little nervous.

"What else can I do? Just release all your breath. ”

"And then?"

"And then wait! Didn't you give you a lightning rod in the last draw?

Wang You: "..."

...............

Cheng Lu sat cross-legged in the spirit gathering array, adjusted his breathing, and directly released all his breath, and at the same time, a dark cloud began to condense in the sky, gathering more and more, black and pressing, as if the sky was about to fall.

"Boom!"

"!" Cheng Lu was frightened by the huge thunder, and looked up at the sky, although there were many dark clouds, there was no thunder.

Cheng Lu: "???"

What the hell is the son of a son of a girl scaring me??!!

Cheng Lu, who was just about to scold the street, heard the faint sound of thunder above his head, so he had to adjust his state and continue to prepare for the catastrophe.

"Click!"

A crisp thunder sounded, and a thumb-thick bolt of lightning slashed straight towards Cheng Lu.

"Poof!" Cheng Lu was so shocked by the thunder that he spit out a mouthful of blood, and the clothes on his body instantly turned to ashes!

"Boom!"

A great thunderclap followed suit

"!" Cheng Lu was frightened again, and hurriedly used his aura to resist, but the lightning did not land as expected

Cheng Lu: "???"

Which bastard scared me this time??!

Cheng Lu forcibly suppressed the anger in his heart and hurriedly refined the power of the Thunder Tribulation that was still remaining in his body.

The Tribulation is a test that the heavens descended for the monks, the Tribulation Thunder is much thinner than ordinary lightning, and the most basic Tribulation is the thickness of a small thumb, but the energy contained in it is extremely pure, and contains the rules of heaven and earth, and the lethality is more powerful than ordinary lightning. And the cultivator's refining of the Heavenly Tribulation is mainly for his own use.

Generally, the Jindan Heavenly Tribulation is at least three, and it increases in turn according to the qualifications of the tribulators, each three is a hurdle, and the maximum is nine.

Nine is the number of poles, and the ninth tribulation thunder is the extreme heavenly tribulation, and its power even exceeds the sum of the first eight tribulation thunders. Throughout the ages, there are not a few people on the earth who can trigger the Extreme Dao Heavenly Tribulation during the Jindan Period, but only a handful can survive after the Nine Thunder Tribulations.

"Click!"

After Cheng Lu refined the first thunderstorm, the second thunderstorm also came as scheduled.

This time, he could no longer mobilize the extra aura to protect his hair, and a large mouthful of blood spurted out, and his hair turned into ashes after his clothes. This thunderstorm was even more powerful than he imagined.

"Boom!"

The huge thunder sounded again, this time Cheng Lu was used to it, no longer affected by the outside world, and quickly sat cross-legged, refining the Heavenly Tribulation, adjusting the state, and doing it in one go.

"Click!"

The third thunder tribulation came, and its power exceeded that of the second one.

Cheng Lu felt that his body was about to be crushed. Hurriedly swallowed a Huiyuan Pill and a Rejuvenation Pill and began to condition his body.

Compared to the third realm, the next fourth thunder tribulation was not as great as the second tribulation to the third tribulation. Cheng Lu had a fairly smooth time after sacrificing Liuyun Suo, but the sweat on his forehead meant that he was almost at the limit.

When it came to the fifth thunder tribulation, Cheng Lu ate two Hui Yuan Dan and one Rejuvenation Pill again, adjusting the state of his whole body to the best.

Finally, after he vomited several taels of blood, he managed to survive.

After the five thunderstorms, the dark clouds began to dissipate, and a little golden light appeared in the sky. Cheng Lu collapsed directly to the ground, he knew that the thunder tribulation had passed.
