Chapter 778

In fact, Liu Wei has been engaged in prosthetic research in Qujiang mansion.

At that time, it was because a constable in the Yamen met a good thief when patrolling the street at night. The constable rushed up recklessly, but unexpectedly, the thief had his accomplice. A group of people stabbed him twice and broke his leg.

After this incident, Fu Zichen was furious and ordered the Yamen to go up and down to arrest the murderer.

Although at last all the thieves were caught in the net, dead and imprisoned, the lost leg of the constable could not be made up.

A constable is a job. If he loses his job, he will lose his ability to work.

Even if Fu Zichen gives his family a lot of subsidies, it will not be a long-term solution.

And that's what happened. Liu Wei began to study prosthetics.

Liu Wei is a student of surgery. He has a full understanding of human organs and limbs, but he needs more than that.

In the end, Liu Wei did her best to install a leg for the constable, but there were many defects.

Now I hear Xiaoli say that an old man with a prosthetic leg can look like an ordinary man. Liu Wei is not surprised, it is impossible.

But Liu Wei can't help but start to think, here, really has such advanced medical technology?

Liu Wei is thinking.

And from now on, Rong Su, who didn't understand a word at all, said again: "that Grandpa just gave you a white jade ring? What did you say? "

What Rong Suo asked was Xiao Li.

Xiaoli thought about it and shook her head: "nothing more."

There was a moment of silence in the hall.

Seeing that everyone was silent, Xiao Li went to her mother and asked quietly, "Dad, why does that old man's artificial limb look so real?"

Liu Wei touched his son's head and lost his mind: "maybe, although the space is different, but some history, in fact, is going in the same direction?"

Xiao Li was stunned and didn't understand her mother's strange words.

Liu Wei just shook her head, and did not explain it in detail.

As a medical student, Liu Wei has the most understanding of medicine, and the history of medicine is certainly not new.

As early as the 11th century, human beings invented artificial limbs. What is the concept of the 11th century in the west, about the Northern Song Dynasty in China.

Since the concept of prosthesis has been brought out for a long time, it shows that the research of prosthesis has been continuing.

In Liu Wei's world, after the 11th century, for a long time, the development of artificial limbs was stagnant. That is to say, no one really studied it, studied it, and really made its research grow, because there were too many wounded soldiers in the war, the first World War, the second world war.

How to make a large number of war wounded amputees return to society has become a problem that European countries are eager to solve. Therefore, after that, the research and development of prosthetic limb has made rapid progress. Later, it has been able to easily return most people, at least a seemingly complete body.

According to Liu Wei's understanding, in the present Qingyun Dynasty, the so-called people who study artificial limbs, their thoughts still rest on wooden artificial limbs, one piece of wood supports one person, but the rigidity is almost 100%.

Liu Wei's prosthesis for the captor added the axis law, which means that it can bend and has higher flexibility, but only some.

Liu Wei had thought about further research, but because of the limited materials, he couldn't make much progress.

But now, hearing Xiaoli's words, Liu Wei began to be curious. How could there be such a lifelike prosthesis here?

"Dad?" Seeing her mother's delay in speaking, Xiao Li called again.

Liu Wei, looking back at his son, said, "go and get the ink, paper and inkstone."

Xiaoli doesn't know what her mother is going to do, but she still goes to get it.

When he got it back, Liu Wei spread the rice paper, wrote and asked directly, "appearance."

Xiaoli reflected that her mother was asking her grandfather about his appearance, and recalled: "her hair is gray, her face has silver whiskers, and her facial features are correct, right..." Xiao Li thought of it, reached out and compared the position of the tail of his left eyebrow, and said: "there is a broken mark here, like it is caused by scar, but it is not obvious."

Xiao Li knew that his mother wanted to paint a portrait, but he was reluctant to narrate a person's facial features in words, so he could only capture features to mark them.

Liu Wei listened and did not rush to write. On another piece of rice paper, she drew a pair of eyes and eyebrows. She asked, "so?"

Xiaoli twisted her head and shook her head. "The upper eyelids need to sink down a little more, but the eyes are full of spirit. The eyebrows are not so high, they need to be shorter."

According to her son, Liu Wei drew again.

Xiaoli was a little satisfied this time, but still said: "the orbit is not so small, it needs to be bigger, and the eyebrows are not all black, half of them are white.

Liu Wei is not impatient. Change a piece of paper and continue to draw.

So adjusted, tested, arranged many times, spent a whole half hour, and finally Liu Wei finished painting a finished product to Xiaoli's satisfaction.Looking at the gray hair on the rice paper, but the kind-hearted elder, Liu Wei can be sure that this is not emperor Qianling, and at the same time, it is not anyone she knows.

However, this person can take out the items of tribute level to give to the child at will. He is impartial. He can find Xiaoli directly. Liu Wei dare not take chances. Therefore, this person's identity must be found out.

Liu Wei picked up the rice paper and looked at it for a while. Then she turned the picture around, handed it to Rong Su and asked, "can you read it?"

Rong Su takes a look and squints.

"Do you know?" Liu Wei asked

Rong Su doesn't speak, but she looks serious.

Liu Wei was suspicious and handed the portrait to Rong Ling. Liu Wei didn't speak, but he was observing Rong Ling's expression.

Rong Ling's expression is very calm. To be exact, his eyelids hardly move.

But how does Liu Wei know about Rong Ling? The more motionless he is, the more Liu Wei knows. The old man in the picture, Rong Ling must be recognized.

Under normal circumstances, when a person sees a strange portrait, his first attitude should be curiosity. Even if he is not curious, he will always look at it more.

Rong Ling's manner surprised Liu Wei. At the same time, Liu Wei began to wonder who the old man would be?

The atmosphere in the hall dropped to the lowest point.

Rong Leng and Rong Su are silent, but they look at each other from time to time. It seems that they have something to discuss, but there are still people around.

Liu Wei's eyes swayed from side to side, looked at this and that, and finally asked thoughtfully, "but do you want me to go out first?"

Both men are silent again.

But at this time, silence is the default.
