Smashing a hundred-ton boulder with a knife, Yang Yu behaved quite easily, and there was not even a trace of sweat on his forehead.

It's just that at the moment, he doesn't seem satisfied.

Naturally, there was a look of disappointment on his face.

Yang Yu shook his head and muttered, "The strength is not enough, there is a momentary lag when the five attacks overlap and merge." It should be more perfect, the incision of these two boulders is not smooth enough, there is a rough feeling, and even the edges have gravel cracks. ”

"Although the Thunder Sword Technique has advanced to the second realm, it still seems that it has not been completely stabilized now."

"It's still a little too reluctant to play."

"When you are fighting, if you meet a real master...... This kind of knife technique with some subtle flaws is not good, and it is easy for people to find the flaws at that moment and target them! ”

"You have to tilt your cultivation time a little bit and spend more time perfecting the Thunder Sword Technique thoroughly."

"With my current strength at the ground level, cultivating the Thunder Sword Technique to the second level is almost the current limit...... Unleash five attacks in a short period of time, all with a soaring speed, so that the five attacks of different times before and after are completely stacked and played as often as one attack! To do this, the requirements for physical strength are too demanding. ”

"The third realm of the Thunder Sword Technique requires nine consecutive attacks at the same time!"

"The nine attacks stacked perfectly, instantly bursting out with a power three or four times greater than the usual attack...... To achieve this level, the physical strength needs at least a heavenly level to be loaded. ”

"Let's do this first, stabilize the second realm of the Thunder Sword Technique. The knife technique has also reached the bottleneck at this stage, and the practice of water grinding can only wait for the opportunity to break through. In the next time, when the Thunder Sword Method is completed, I will go all out to cultivate the power of the life soul to the peak. ”

Yang Yu's life soul power was much, much stronger than a month ago.

The second part of the Hundred Refining Soul Score has been listened to more than a hundred times, and each time it is extremely painful to listen to, and the spirit and soul are penetrated by the violent dark force triggered by the score, and then heal and repair...... Repeatedly, Yang Yu's life soul power is now at least ten times stronger than before!

The giant mantis beast team he cultivated under his command had also grown in size, and now it had a scale of two hundred and fifty heads.

"It's almost time."

Yang Yu's eyes glanced in the direction of Shangjing City, and he also muttered in his mouth.

"Idiots from the Ghost Baby Gate, we'll meet again soon."

After finishing speaking, Yang Yu put all the thoughts in his mind away.

He also threw himself into the next round of practice again...... Today's knife practice time has been increased, and it will be increased by two hours again!

The wind is once again raging in the wasteland stone forest.

A heavy thunder sword shadow also emerged, sometimes secretive, sometimes light, sometimes domineering, like a thunderbolt falling!

……

There was no time for the practice, and two weeks passed in the blink of an eye.

Two weeks later, Yang Yu had finally completely stabilized the second realm of the Thunder Sword Technique, and the power of all his sword attacks had also doubled.

After the sword technique was practiced, Yang Yu's cultivation plan changed again.

From this day on, the time he spent practicing his sword techniques was significantly shortened, from four hours a day to one hour...... This one-hour sword practice time is mainly to familiarize him with the combat knife in his hand at all times and avoid being unfamiliar.

The path of cultivation is like sailing against the current, even if the cultivation of the secret technique of the sword technique is successful, even if the realm of the sword technique is improved...... If you let it go and don't ask, then you will also be rusty and regressive.

It takes an hour every day to familiarize yourself with the sword in your hand and keep the realm of sword magic and secret art stable, which is enough time!

Letting go of his fanatical cultivation of the Thunder Sword Technique, Yang Yu threw himself into the cultivation of the Soul Soul.

At the same time, experiments on various wasteland insects have become more frequent.

In the underground, a small laboratory has been quietly built.

Yang Yu's cultivation of the Hundred Refining Soul Forging Score could not be continued, and listening to the second piece of music was quite physically demanding, and he had to endure inhuman pain all the time. After every hour or two of practice, he would rest for a while.

This time of rest is the time for Yang Yu to conduct biological experiments on various wasteland insects and beasts.

Fanatical experimentation.

Crazy Spiritual ...... Yang Yu's life soul power and the use of life energy became stronger and more handy in the following time.

When he stayed in this wasteland for two months and nine days, he had even developed a new method of using his life energy.

That's gene extraction and modification technology!

This kind of power has been mentioned in the Zerg inheritance information, and for the use of life energy, each Zerg cultivator has a different route, different opinions, and different future developments.

Life Enhancement!

Gene Extraction!

Life Makeover!

There are even more wonderful ways to use life energy, all of which can lead to a path of light.

All this needs to be explored and mastered by Yang Yu, who is the inheritor of the Zerg.

When one day, the life energy evolves to an incomparably strong level, Yang Yu's position in the universe is probably incomparably strong, enough to become a figure like a hegemon.

……

In the underground, in a dimly lit quiet room.

Yang Yu sat cross-legged on the ground, practicing.

No one bothered him here, Zhao Zixuan was also busy in the laboratory, as Yang Yu's assistant, she was responsible for keeping an eye on some insect poisons that were being experimented, and always observing the changes in them after being eroded by life energy.

At this moment, in the airtight quiet room, the dust and gravel on the ground shook.

Sitting cross-legged, Yang Yu's body surface also appeared from time to time a vague and mysterious power, which was sometimes violent, sometimes peaceful, and faintly affected the surrounding environment.

And Yang Yu?

His face was extremely hideous at the moment, his forehead, body, and all the pores of his body were open, and beads of sweat the size of beans were constantly seeping out.

Clearly, he was in great pain.

The pain was tens or hundreds of times more intense than the most cruel torture in the world of ordinary people!

Without this kind of intense pain, it would be impossible for Yang Yu, who could strengthen his body to the peak of the earth rank, and even fight head-on with ordinary heaven-level powerhouses, to this extent.

Call~~~~~~~~

Call~~~~~~~

His chest was heaving and contracting, and his breathing was like a bellows that had broken a gap.

Five minutes, ten minutes, half an hour......

Yang Yu persevered, and after an hour, he finally opened his eyes, and a mouthful of turbid air came out of his mouth, and his whole body relaxed.

"The cultivation effect of the second piece of the Hundred Refining Soul Forging Score is getting worse and worse."

"After a few more days of cultivation, it is almost time to reach the limit of this stage, and I can't continue to improve the power of my life soul."

Yang Yu whispered in the darkness, and his eyes also glowed with inexplicable brilliance.

It lasted more than two months.

Most of the summer has passed, and at this moment, the outside environment, the scorching heat has reached sunset.

He has finally raised his strength to a state close to the current stage of perfection.

Soon, he will be able to return to Shangjing City without any scruples.

Yang Yu is full of anticipation.

Hiding for more than two months, suffering in this wilderness, he also held back his anger.

This nameless fire needs blood to wash away!

Just thinking about things, Yang Yu's brows suddenly furrowed, and he turned his head to look at the door of the quiet room.

Thundered~~~~~

The stone door of the ashram vibrated and slowly opened.

Zhao Zixuan, who was dressed in white and looked like a beautiful fairy, also walked in.

"Master, are you awake?" Zhao Zixuan was surprised and looked at Yang Yu.

Yang Yu looked at her, and there was some displeasure between his eyebrows.

"Didn't I tell you that you shouldn't just come in here if you don't have something important?"

"What's the matter?"

"Don't be angry, master." Zhao Zixuan stuck out his little tongue: "I'm here to disturb the master, naturally I have something good to report." There was movement in the laboratory, and some of the genes extracted from the 370 kinds of insect poisons that were being tested could finally be used after half a month of cultivation and transformation. ”

"There are some pretty good genes in it, just right for the Mantis Beast troops."

"I believe that with these things, the overall combat effectiveness of the giant mantis beast force can also be raised to a higher level and reach a stronger level!"
