Based on Liu Zhengyang's knowledge of medicinal pills, he can basically be sure that the old man used something like a healing medicine.

Although I don't know what's going on, why the recovery speed is so fast and the duration is so long, as long as it is a drug for healing, there will definitely be a time when the power of the drug is exhausted. Moreover, the recovery of the injury itself will consume the energy of the monk, and he does not believe how long the old man can last.

Unless the old man also has an elixir in his body to help him restore his energy.

But even so, the old man would last a little longer at most.

While fighting, Liu Zhengyang said, "Damn old man, don't you feel pain when you fight me like this? Even if the injury can be recovered, the pain of the injury is real. You have endured such pain many times, and your spirit can bear it. ?"

"You don't have to worry about my affairs." The old man was still fighting in a muffled voice.

And when Liu Zhengyang saw that the old man didn't talk too much, he stopped wasting his saliva.

He put all his energy into fighting.

The old man's broken bones also increased.

In order to exacerbate the pain of the old man, Liu Zhengyang even deliberately attacked the bridge of the old man's nose and ribs. And as the number of injuries increased, the old man's face gradually turned pale.

Bean-sized beads of sweat were constantly rolling down his face.

"Hey, old man, can't your recovery ability keep up?" Liu Zhengyang teased: "Why did your face become so pale? Usually, such a reaction is not only when you lose too much blood or you are very scared. ? So which one do you belong to?"

"Stop talking nonsense! Even if you feel sick again, this old man can fight with you for another year." The old man gritted his teeth and kept attacking Liu Zhengyang's face, as if he wanted a tooth for a tooth and an eye for an eye.

However, Liu Zhengyang's physical strength far exceeds him, and fighting with pure physical strength is not as exhausting as the old man's exaggeration.

He is still full of energy.

He easily blocked all the attacks of the old man, and said calmly: "I found that your recovery ability is really amazing, and it has not slowed down until now. I really don't know what's going on with your body. But no matter what, I They have found a way to break you."

"Hmph, nonsense." The old man didn't believe it at all.

Liu Zhengyang didn't care, anyway, he could use his actual record to explain it.

When he said that he had a way to target the old man, every time he came into contact with the old man, he would inject a ray of demonic energy into the old man's body.

Although because of the short time, there is not much magic energy that can be injected, and it will be offset by the energy in the old man's body in an instant, but after a long time, a few strands of magic energy have survived, so that the old man has no way to spare part of the time and energy to eliminate.

The pain of the demonic energy invading the body made the old man's face even more ugly.

And after the first success, the old man's resistance is getting weaker and weaker.

Liu Zhengyang has more and more devil energy in his body.

When the demonic energy was enough to compete with the immortal energy in the old man's body and hurt the old man's body, the old man's resilience finally couldn't keep up.

His face didn't change: "You... you still use such a fighting method? Why have we never heard of it?"

"That's because your information is not well-informed. It's not the first time I've used it." Liu Zhengyang said leisurely: "It's just that the opponents I have encountered in the past are not strong enough, and I don't need this kind of fighting method at all."
