Countless thunders continued to bombard the black shadow.
"Hahaha, idiot. I have survived since ancient times and can be killed by an ignorant kid like you? Stop making trouble. This thunder is like tickling." The black shadow laughed wildly.
Lu Yu's expression did not change, he continued to control the Five Thunder Zhengfa, and the thunder struck the black shadow fiercely.
"It doesn't hurt at all, kid, haven't you eaten?"
"It's useless. This little thunder can't cause any harm to me at all."
The black shadow continued to provoke, but Lu Yu seemed not to hear what he was saying, and the countless thunders became more powerful.
Boom! Boom! Boom!
After a long time, seeing that Lu Yu still had no intention of stopping, the black shadow suddenly fell into silence.
"Are you sure you want me to be your master?" Black Shadow gritted his teeth.
Lu Yu said calmly: "I won't worry if you don't control your true soul."
He still doesn't know the identity of this dark shadow, but since it has survived from ancient times to the present, Lu Yu must treat it with caution.
"Okay! Since you want my true soul, I will give it to you!"
The black shadow seemed to have made up its mind, and a flash of red light instantly flew out of the black shadow and penetrated into Lu Yu's eyebrows.
In an instant, Lu Yu's whole body froze, motionless.
He only felt that the true soul in front of him seemed to contain endless power and was about to tear his soul apart.
As Lu Yu stood still, the thunder around him stopped instantly.
"If you want me to recognize you as your master, I'm really sorry you can think of it. Even if you are a true immortal, you don't want me to recognize you as your master. Can you bear my soul?"
With a sneer on his face, Heiying walked towards Lu Yu step by step.
"My physical body has been destroyed. This guy is pretty good, but he has obviously only scratched the surface of his Taichu body skills."
The black shadow approached Lu Yu and began to look at Lu Yu up and down.
"The muscles and bones are well tempered, but if they want to become my physical body, they are still not strong enough!" The black shadow suddenly exhaled a breath of black air and fell on Lu Yu.
A crackling sound suddenly came from Lu Yu's body.
Every muscle and bone became stronger and stronger at this moment.
Because Lu Yu was still in a coma at this time, he was not aware of the pain caused by the changes in his muscles and bones.
"Too weak! Too weak! This Taichu body must have been modified by human demons. The person who taught him the technique must have had no good intentions!"
"If you reach great success in cultivation, I'm afraid this kid will be tricked to death. Haha, but since your body is under my control, I won't be played with like this."
The black shadow suddenly made a hand gesture, and a purple rune condensed from his hand and fell into Lu Yu's body.
There was another roar, and Lu Yu's body became stronger again.
At this moment, Lu Yu's whole body's muscles, bones and meridians were all shining brightly, as dazzling as the vast galaxy.
The black shadow looked up and down for a moment, then nodded: "Yes, I can finally see it through, hahaha! If I seize you, I will be able to get out successfully!"
The black shadow laughed and rushed directly towards Lu Yu's soul.
But suddenly, a huge Tai Chi vortex gradually emerged above Lu Yu's soul.
This vortex was not obvious at first, but once it appeared, a strong hurricane formed around it.
When the black shadow saw the Tai Chi diagram, it suddenly looked like a mouse meeting a cat and screamed: "You actually got this thing, no, this is impossible!"
He struggled to break free from the shackles of the Tai Chi diagram, but the hurricane formed by the Tai Chi diagram was extremely strong, and the strong hurricane instantly surrounded the black shadow.
