Leng Chuan watched from the sidelines, nodding his head clearly.

He knew that Xu Bai had been conducting experiments, but he didn't expect to be experimenting in this area.

Mutter!

Xu Bai pressed the starting lever, and the entire machine lit up, he looked at the doctor inside, and nodded to Dong Xiaoge opposite.

Then, he lowered his head and focused on the manipulator in front of him.

The reason why he chose the doctor as the test subject was not only because the doctor was beyond ordinary people, but also because of his physique that was immune to pain.

He knows what will happen to those who have used his human body enhancer, the constantly mutating body is like a cancer cell, which will cause the host to multiply indefinitely and die, and that kind of extreme pain is basically worse than death.

If you can't bear the pain, you're likely to die without completing the experiment.

Of course, the main thing is that the doctor has used that strengthening "stimulant" to strengthen the body five times, and the physique that has recovered after experiencing trauma has a higher compatibility than ordinary people.

That is, he died and came back to life, and he didn't mind dying again.

However, there is no wrong reason.

Xu Bai exhaled, pressed his fingers on the operating instrument, and looked at the doctor inside.

A colorless liquid slowly flowed down from the catheter, and everyone in the experimental field breathed nervously, waiting for the next change......

"Wait!"

Just then, a voice interrupted the tense moment.

Everyone looked at the black dog with their hands raised, and even Xu Bai stopped the experiment.

It's no secret that experiments in this area will start sooner or later, so not only Black Dog, but also Evil Fox and Thunderman are also present.

And hearing such an interesting thing, Tiger Shark and Hayato also rushed over.

"The ......"

The black dog walked up, looked at Xu Bai, then looked at the doctor, and said:

"I was bitten by a dog before, I didn't get vaccinated, not only did I survive without any problems, but then, I was seriously injured once, I lost a lot of blood at that time, I was injected with blood from other blood types, and I survived afterwards."

"So, what do you want to say?" Xu Bai still looked at him suspiciously.

"As I said earlier, the requirement for the experiment is a strong physique, but the experiment itself is to mutate the body and survive, and I think that an extraordinary physique is more suitable for this experiment than a physique, so I ......"

After the black dog finished speaking, his eyes looked at Xu Bai meaningfully.

"Constitution ......"

Xu Bai only thought about it for a while, and then slapped his palm, yes, why didn't he think of it?

A strong physique may not be suitable for experiments, and a physique that is different from ordinary people is the best first choice!

After thinking about it, he looked at the black dog with burning eyes.

"I ......"

The black dog touched his head, he already knew Xu Bai's thoughts.

"Well, that's it."

Xu Bai nodded deeply at him, for him, it was not impossible to temporarily change the test subject, anyway, which test subject was only relative.

Then, confused, the doctor walked out and changed to a black dog to enter.

The black dog didn't expect that he would become an experimental subject just by making a suggestion, and the others looked at him with admiration, after all, not everyone has such courage.

"How's it going, you can't go back when you start?"

Although he had already made his own decision, Xu Bai still had to ask his opinion.

"It's really not good, you can replace me." The doctor touched his face and echoed outside.

The black dog looked inside, and then at the arm, but the arm had become a monster, and he didn't mind, and, even if he failed, he would only lose an arm.

After figuring it out, he seemed to have stepped into the execution ground, walked into the glass warehouse, connected his body to the catheter, and lay down.

"Let's get started."

Xu Bai nodded to each other, activated the operating lever, and the familiar liquid flowed down, and he also reduced the purity of the extract for safety.

Everything that needs to be done has been done, and the next thing is to see the creation of the black dog......

The liquid slowly flowed into the arm with the catheter under the gaze of all eyes, and at this moment, the black dog's heart beat suddenly!

Thump~

With this heartbeat, the data starts to beat, up and down, and changes so fast that it's hard to be avoided.

"Dong'er!"

Dong Xiaoge followed Xu Bai's operation, and in the next second, he shouted out in pain like a beast roaring.

"Keep the shock!"

The black dog was lying on the experimental bed, his expression was as if it had just changed from the sky, hideous like a devil, not shouting, but roaring out one after another.

"Ahh

The high-voltage electric shock on the body, blocking the blood flow in the arm, at this moment, no matter how much the black dog endured, he also lost his mind because of the double pain.

Because his whole body was tied, no matter how much he struggled, he only moved on the test bed.

"Ahh

"Ahh

"Ahh

At this moment, a new piece of red flesh grew from the arm, and similar red flesh grew in other places, slowly turning black under the gushing black.

It's not an over-expansion of flesh and blood, nor an irregular growth, but a regular one that has a life of its own.

"Good, that's it!"

Xu Bai sat excitedly in the operation position, and the data that changed at the moment was also stable at a value, as long as he continued to persevere, he could do it.

The black dog, who was in pain, did not know the changes in his body at all, only he knew that the pain in his arm was far more than the body of an electric shock.

Suddenly, the shackles on his hands stretched out in a circle, and the huge arms were exposed, and countless flesh and blood wrapped the arms into huge arms, all black, as if they were the arms of a monster.

At this moment, the appearance of the original arm can no longer be seen, just a monster with black hands.

After a long time, the black dog's roar stopped, and only one black arm was left on the test bed, expanding to the exploding muscles.

The black dog gasped and looked at his arm, a smile curled into his mouth.

"Is this my power?"

He didn't have to feel it, he could feel the terrifying power above, and he could easily crush everything he saw in front of him.

"Boss, is this okay?"

He turned his head to look at Xu Bai outside, thankful that he could recover so quickly from the state he had just had.

Everyone else outside the glass warehouse was shocked, and the black dog's howl of pain just now startled them, and everything in front of them was beyond their comprehension.

Xu Bai didn't reply, his eyes were observed on the arm projected and enlarged on the screen, the situation was not as wonderful as he imagined, the experiment was successful for the time being, but the follow-up problems were equally troublesome.

If you look closely, there are still proliferating pieces of flesh on the surface of the arm, like wriggling maggots.

Nausea is secondary, and when these cells proliferate proliferate is the problem.

On the catheter, Xu Bai injected the black dog with a stream of blue liquid, and the black dog's arm immediately shrunk and returned to its original appearance.

This is an inhibitor that temporarily inhibits the mutated cells of the black dog, so that the arm can be restored to its original state, and it can be used to change again, and it can also play an effective role in the problem of excessive proliferation.
