Hand over the jade seal first [Infrastructure]

"Prosthesis?" Xiao Xuan was stunned for a moment, a little surprised and a little dazed, he had never heard of this word before.

Xiao Zirong thought for a while and said: "It can't be regarded as a prosthesis. Hey, I don't know what to call it. It's just a thing that can assist walking. I'm not sure if it works well. A wheelchair is simpler. It’s more convenient to have people push you up there.”

These two things were put on the agenda by Xiao Zirong after it was confirmed that the emperor would come.

The so-called prosthesis is actually a wearable device. Xiao Xuan had a broken leg but the bone was not connected properly, resulting in different lengths of the two legs. What Xiao Zirong needs to do is to make up for the length of the two legs, and at the same time alleviate Calf pressure.

In fact, this kind of thing is not as easy to use as crutches, but the emperor... should be more concerned about the image, and crutches are really not very good-looking.

If you are in a wheelchair, it is okay to try it occasionally, but it is not very friendly to the leg muscles in the long run.

Xiao Xuan was actually very interested in wheelchairs at first, not because he liked to sit, but because he had never seen this thing before and naturally became curious.

Seeing Xiao Xuan's eyes glued to the wheelchair, Xiao Zirong asked someone to push the wheelchair over.

The wheels of the wheelchair are made of simple wood, and there is only a layer of shock-absorbing leather pad installed on the outside, but the shock-absorbing effect of this leather pad is average, mainly to reduce the vibration of the wheelchair when walking on the green brick road.

As for other grounds... It is impossible for Xiao Xuan to go to those rough places in a wheelchair.

The two small wheels on the front of the wheelchair are very flexible. Needless to say, this kind of universal wheel is also made by hand, that is to say... This wheelchair is not only unique, but it is also difficult to promote.

Xiao Xuan watched Xiao Zirong's way of turning the wheelchair flexibly became more and more interesting, so he sat in the wheelchair directly, and then let Xiao Zirong push him around the main hall twice.

Xiao Zirong even said: "Actually, this one can be controlled by oneself. Next to the two wheels, look here... There is a circle of push hands, which are used to control the wheelchair. You can move forward or backward."

Xiao Xuan didn't know how to do it at first, not because he couldn't walk, but because he didn't know how to turn flexibly. It took him a while to get used to it.

Xiao Zirong stood aside. He originally intended to make the wheelchair a means of transportation for Xiao Xuan, but now it seems... Well, Xiao Xuan probably regarded this thing as a toy.

But thinking about it, how could Xiao Xuan lack a means of transportation?If he didn't want to leave, he could sit on a sedan chair and be carried around. The comfort level should be better than a wheelchair, since a wheelchair needs to be pushed around anyway.

So Xiao Xuan is interested in wheelchairs purely because of the fun, and after playing for a while and sweating, he will focus on the wearable prosthetic limbs aside.

The wearable prosthesis is actually more like adding a heightening pad to him. In the past, Xiao Xuan tried to balance the length of his two legs by adding something to his shoes.

But I have to say that the effect is not very good, it is uncomfortable when walking, and it will cause some damage to his ankle in the long run.

He would rather not wear it than use it since then.

Now this thing is much the same, and Xiao Xuan wears it with the idea of ​​not wasting his nephew's filial piety.

However, after putting it on, he noticed the difference.

In the past, all the pressure on the thing that increased under the foot was on the ankle of the right foot. After all, if the body is unbalanced and forced to make up for it, the "shorter" side naturally needs to support more strength.

But now this one is not the same as the previous one, now this one distributes the power more on the calves and knees.

That thing that looks like a boot actually has a skeleton inside!

This skeleton fits perfectly below his knees, and the skeleton is connected to the "boosting pad" below, so that the strength is dispersed.

Of course, Xiao Zirong actually didn't know the difference between Xiao Xuan's legs, even Xiao Xuexing didn't know this statistic.

In other words, except for the doctor who has been helping Xiao Xuan with massage and treatment, no one else will know.

In this case, this wearable device is not considered tailor-made, so Xiao Zirong directly made it into a prosthesis that can be adjusted flexibly.

The flexible adjustment lies in the "heightening pad". The container under which the "heightening pad" is placed can be opened, and there are layers of bamboo boards inside. Each layer of bamboo boards is very thin, and the outside is made of relatively strong cloth. To wrap it, the bamboo board inside can be taken out.

So when Xiao Xuan put it on, Xiao Zirong directed the little eunuch beside Xiao Xuan to adjust the increase or decrease of the bamboo board.

After adjusting until Xiao Xuan felt that it was almost the same, Xiao Xuan tried to take two steps.

At first he was not used to it, so he subconsciously put all his weight on his right foot, but at this time his right leg was already the same length as his left leg, and his waist and hips were also in a balanced state, which made his posture look like Very strange.

Xiao Zirong helped him to walk slowly and said, "It's definitely uncomfortable to wear this at first, after all, it's not my own legs and feet. If uncle thinks it's okay, you can try it a little bit."

Xiao Xuan is indeed adjusting a little bit, he has to get used to having a complete right leg.

This is definitely not an easy task, Xiao Zirong observed his expression and asked softly: "Will the leg brace be uncomfortable?"

Because it needs to play a supporting role, this bracket is made of iron. Even if Xiao Zirong added a thick layer of kapok on the outside of the bracket as a buffer, it definitely doesn't feel good to be poked by such a hard object on the leg.

In fact, even with such a buffer, walking for a long time will wear down the calf.

So it's still the same sentence, in Xiao Xuan's situation, the crutch is the most suitable.

But the problem is that Xiao Xuan doesn't need to walk for a long time, as long as he can rely on his own strength on some formal occasions, he can walk over with his head held high, then sit down, and then walk away after the show is over, and when he goes out, he can sit in a chariot or something like that. , will not cause too much burden on his right leg.

This is also one of the reasons why Xiao Zirong is willing to take out this imperfect thing.

Xiao Zirong originally wanted to take Xiao Xuan to see the city wall after offering these two things.

As for whether Xiao Xuan will use it after all is his own business.

Whether it is practicing the operation of a wheelchair or practicing walking, Xiao Zirong needs to leave space for the emperor. He thinks that the emperor probably doesn't like to appear too embarrassed in front of others, especially in front of juniors.

As a result, he felt that he seemed to have underestimated Xiao Hyun's desire to walk normally.

In the past, Xiao Xuan longed for someone to heal his leg, but as he grew older, he knew that this was almost impossible.

He seems to have given up on that idea since then, and now...although his leg hasn't been healed, he has a chance to walk like a normal person.

So he would rather visit later and practice more.

He didn't even drive Xiao Zirong away, and he would express his feelings during the practice. If there was something uncomfortable, he would choose to ask Xiao Zirong, and then see if Xiao Zirong had any solutions.

Xiao Zirong deeply felt that His Majesty the Emperor is really a very cooperative "patient", but...he is not a doctor, nor is he a person who specializes in making medical equipment. It is really difficult for him to correct the inadequacies of the prosthetic limbs on the spot .

Fortunately, he has the backing of the library, so he can search for all Xiao Xuan's questions, no matter whether he understands them or not, at least... he can answer them. Anyway, it is impossible to adjust on the spot, because when he did it, he was a overall.

It wasn't until this time that Xiao Zirong realized his "arrogance".

Yes, arrogant, when making this thing, he instinctively felt that this is a very advanced thing that does not exist in this era, so it must be useful.

But I forgot that this thing is not a glass or a mirror, and there is no need to consider the user's feelings, or if I can accept these two new things, I won't have a bad feeling.

Things like prosthetics need to be tailored for the user.

However, Xiao Zirong wanted to present the treasure too much, so he made it in advance.

When he was doing it, he only knew some rough data of Xiao Xuan, calf circumference?have no idea.Knee circumference?do not know either!Ankle circumference?I don't even know.

The only thing that is known is the size of the sole of the foot.

Xiao Zirong was not a person who would not admit his mistakes, so he immediately asked Xiao Xuan to take off his prosthetic limb.

Xiao Xuan was a little surprised and asked, "What's wrong?"

Xiao Zirong looked at him seriously with some guilt and said: "This thing should actually be made according to the specific situation of my uncle. It's my fault. I just wanted to make it as a surprise for my uncle, but I forgot that if this kind of thing is not done well, it will be dangerous." It's very uncomfortable, take it off, uncle, I'll have someone measure your legs, and then make a custom one."

After Xiao Zirong finished speaking, he repeatedly pleaded guilty. He admitted this kind of harmless mistake very readily.

Xiao Xuan laughed after hearing this, very happy, patted Xiao Zirong's shoulder vigorously and said: "Good boy, it's not your fault."

He is the emperor, can some details of his body be known casually?

Even if Xiao Zirong wanted to find out, he might not be able to find out, especially if it involved his injured leg. Even if he knew in advance that there was such a thing as a prosthetic limb, to be conservative, he would let Xiao Zirong make one first to see , let’s talk about other things.

Now he feels very good. Although he is a little uncomfortable, he is not unable to restrain himself.

He has forgotten when was the last time he felt such a smooth walk, 20 years ago?Or 30 years ago?

In short, it has been very long, so long that he can't even walk normally.

Xiao Xuan is very reluctant to take off this prosthetic limb at the moment, he is gradually getting used to this leg that does not belong to him, and when he gets used to it completely, he may be no different from a normal person.

Xiao Zirong never thought that the emperor's stubbornness would be such a headache.

He broke apart all the reasons and said that he himself was not afraid of admitting mistakes, but Xiao Xuan felt that this was nothing.

Xiao Zirong said earnestly: "Your Majesty, this is something that needs to accompany you for a long time. I must make you feel comfortable."

Xiao Xuan found that his nephew didn't even call his uncle, and his face that still had a little baby fat was rarely very serious.

He is very happy, which means that his nephew cares about his body very much.

He didn't want to worry the children too much, so he said, "It's okay, it's not that uncomfortable."

Xiao Zirong had a headache, and after thinking about it, he directly resorted to his trump card: "Uncle, this production is not difficult, after all, one has already been made, and there are some spare materials, as long as the value is finely adjusted, in this process You may find it boring, but...do you want to see the new plow I made? This kind of plow has expanded the scope of spring plowing by one person in Taoyuan City by [-]%."

Xiao Xuan's attention was indeed attracted, and he asked with some surprise: "Thirty percent? Rong'er, don't talk nonsense."

Xiao Zirong waved his hand: "Come here, bring the land record book and household registration book."
