As an ancient, and also a ruthless and murderous ancient, Cheng Mi has never done any bad things, never seen any scenes, and is naturally not afraid of one leg in front of him.

Far from being afraid, his eyes lit up.

She remembered that He Wenhao once said that He Wenjie used high technology to make a leg by himself, called a stem cell or something.

She didn't know much about those modern medical terms, but she remembered that he had cultivated a leg of his own, but she couldn't connect it.

When I heard it, I was shocked that there was such a miraculous thing in this world.

Now I see it with my own eyes, and in addition to the shock, it is doubly shocked!

Moving closer, she noticed that the leg was no different from a real person's, at least to the naked eye, it was flesh and blood.

Cheng Mi frowned, thinking that he might have thought wrong, this was a human leg, not the one made by He Wenjie.

He Wenjie didn't have much appetite, he sat and didn't eat, waited for a while, and didn't see Cheng Mi come back, he was a little puzzled, looked around the laboratory, and finally found someone in front of the petri dish.

"What are you looking at?"

A man's voice suddenly came from behind him, startling Cheng Mi, who was lying on the glass compartment and looking.

Although it showed only a slight stiffness of the body.

She turned around and pointed to the leg in the petri dish, "This is ......"

"My legs." He Wenjie's tone was light, his eyes glanced at the petri dish, and his eyes were complicated.

This is his most proud masterpiece, he managed to develop a leg, but it stopped there!

The stem cell culture technology has been successful, but the bone cell regeneration technology has not progressed and cannot be connected.

Maybe it's really his whims, where in this world is there a reason that a leg that has been broken for more than ten years can still be connected.

It's just that I'm not reconciled!

He has worked hard for more than ten years, but he just wants to get back on his feet, but he just wants to prove himself.

There is also the hope of the He family, the He family has become more and more bitter over the years, and almost all their hopes have been invested in him, no matter how hard it is, even if the branch hospital is constantly closed, it has never stopped supporting his research.

However, in the end, he still achieved nothing.

He Wenjie closed his eyes and hid all the negative emotions in his eyes.

Over the years, he has become accustomed to carrying all the pressure on his own, because no one can help him.

"How?" Cheng Mi was very curious.

Even if her alchemy skills have reached the point of being superb, she will definitely not be able to make a leg!

It's so rebellious!

He Wenjie is not a person of many words, but when it comes to the field he is good at, he likes to share it with others.

Maybe he will never be able to stand on the world stage and share his research results with the world in his life, and it would be nice to have an audience.

"Stem cell culture technology."

"What are stem cells?"

Cheng Mi looked ignorant, the word cell did not exist in ancient times.

"Come with me."

He Wenjie took her to a computer and put the projection on the projector opposite.

Above are some very complicated and unfamiliar diagrams, with text next to them.

"This is stem cells, which are a kind of multipotent cells with self-replication ability, and under certain conditions, they can differentiate into a variety of functional cells, which are called 'universal cells' by the medical community......."

Those obscure scientific terms can make it difficult for Cheng Mi, an ancient man who doesn't know anything.
