Fang Jifan recorded all these.

To be honest, Zhang Sheng is actually very professional. He understood many things he hadn't thought of after listening to him.

"Is there anything else?" Fang Jifan looked at Zhang Sheng with a curiosity look on his face.

"There's another thing." Zhang Sheng slowly stroked his beard and said lightly: "Let's go back, don't come to my house."

"Why?" Fang Jifan roared.

Zhang Sheng's old face turned red: "Because...because..."

Then, his eyes lit up: "Because if you come and are seen, they will know that you and I should cooperate with each other inside and outside. Such matters are naturally confidential. Do you understand my meaning? Don't you and I will not be able to visit each other in the future, even if you walk on the road, don't say hello."

Fang Jifan narrowed his eyes: "Don't you dislike me?"

Zhang Sheng seemed to have been seen through his thoughts, his old face turned red again, and his face was not thick enough. He took a deep breath and said loudly: "What are you talking about?"

"Oh." Fang Jifan nodded: "Then, I will say goodbye."

Fang Jifan said goodbye and went out of the hall, but saw Zhang Yuanxi, who was leaning on a cane, limping in the front yard.

When he saw Fang Jifan, Zhang Yuanxi smiled and said, "Prince, are you leaving now? Don't you stay at home and have a bite of it?"

Fang Jifan said in his heart that an old fox like that actually gave birth to such a stupid and innocent son. In this way, the child that a naive person like me, would the child born is a little fox?

Fang Jifan said: "I won't eat anymore, I'm busy."

"Oh, then you have to come often when you have time." Zhang Yuanxi said: "Students will send you there."

He leaned on a crutch and limped to send Fang Jifan.

Fang Jifan seemed embarrassed and said, "Forget it, you go back."

Zhang Yuanxi said: "You are a guest, this is what you deserve. You must think that my legs are not bad, but students are used to it. Students like to walk like this. Maybe one day, they can really walk freely?"

Fang Jifan thought to himself, fool, there is no miracle in this world. He looked at Zhang Yuanxi's legs and saw that his calves were intercepted. Fang Jifan said, "How did he hurt this?"

Zhang Yuanxi said sadly: "It's better not to mention these things."

Fang Jifan said: "Maybe, you can try it out."

"What?" Zhang Yuanxi looked at Fang Jifan in surprise.

Fang Jifan said: "Come on, I'll measure the size."

Fang Jifan casually found a rope, roughly measured Zhang Yuanxi's foot circumference and length, and marked it online, and said: "You have to go out for a walk more, what's the future for staying in the yard."

Zhang Yuanxi wanted to say something, but Fang Jifan had already left.

…………

When he returned to the West Mountain, Zhu Houzhao had been impatient: "Come quickly, let's think about mining again. I have already thought about it, let's..."

Fang Jifan sat down and crossed his legs: "No need to think about it, there are already all the solutions, which are much more clever than His Highness's methods."

Zhu Houzhao laughed: "You don't understand many things, I..."

Fang Jifan said, "But Zhang Butang understands it. Not only does he understand it, but he also teaches all the tricks here. Do it according to his method. It will definitely work. Please wait. I will write it down and your highness will understand it yourself. I'll be in a hurry and there will be something to do later."

"What else?" Zhu Houzhao looked surprised.

Fang Jifan stared at Zhu Houzhao and said, "Make a leg."

Zhu Houzhao's eyes shining: "Do it? How to do it? Is it to break one leg? Whose leg is broken? You said, why don't you call me this good thing? Oh my, I have long had this idea and I can't find any opportunity."

"..." Fang Jifan looked at Zhu Houzhao with a caring and mentally retarded look... and said earnestly: "Your Highness, you have grown up, don't always shout and fight and kill like this."

After writing down everything that Zhang Sheng had said, Fang Jifan went to work hard on his own affairs.

Making prosthetics is very troublesome.

This requires both lightness and firmness to be fixed on the legs and ensures that people can barely walk.

Fortunately, Zhang Yuanxi's calf was broken, which was equivalent to making him a special shoe.

It also needs to be worn, softer...

Fang Jifan ordered people to use fine steel to make a steel frame. This steel frame needs to be as thin as possible, but can withstand enough weight. Then, a layer of rubber is placed in the inner ring.

The rubber was brought back by Xu Jing. However, when using rubber, you need to consider the comfort of wearing, so that there is a certain buffer between the legs and the steel frame. In addition, leather is covered in the inner circle, but after it was made, Fang Jifan was very dissatisfied.

The reason is still in this material. The current steel weighing capacity is too low, so it needs to support a person's weight without deforming the prosthesis, and better steel is needed.

Fang Jifan found a blacksmith and asked them to re-melter the steel. After experimenting several times, he barely found a good piece of steel, and then made it into a boot style, then covered it with rubber and leather in the inner circle. He tried it and said that the "boot" weighed roughly four pounds, so it could barely be worn.

The next morning, Fang Jifan arrived at the Zhang family excitedly. When the Zhang family's concierge saw Fang Jifan coming, his face looked ugly. Fang Jifan obviously saw a slap on his face: "My master is on duty."

Fang Jifan said, "It was because you knew that your master was on duty that he came."

“…”

"I'll find your young master."

The concierge looked at Fang Jifan vigilantly: "Why?"

Fang Jifan suddenly became angry and raised his hand and slapped him in the face.

Bang.

He knocked the doorman to the ground: "You go out and ask us Fang Jifan, do you need a reason to do things? Get out of here and don't ask, it will blind you."

As he said that, he started directly and shouted: "Zhang Yuanxi, come..."

The Zhang family was in chaos and many people dared not approach and looked from afar. After a while, Zhang Yuanxi limped: "Gui, you..."

"Come on, let's go into the house to talk." Fang Jifan said happily: "Your father and I are friends for ages. Don't call me the chief lieutenant, call me dad, no, call me uncle."

“…”

Zhang Yuanxi limped and followed Fang Jifan into the hall. Fang Jifan took the bag and took out the boots.

When Zhang Yuanxi saw this, his face turned red.

This inconvenience in legs and feet is his biggest privacy. Now Fang Jifan actually took out a boot. Is this going to deliberately mock him?

Fang Jifan said with a smile: "Come on, come on, let's try it out, is it appropriate?"

"..." Zhang Yuanxi was stunned.

Fang Jifan directly pressed him on the chair and roughly lifted his skirt. Zhang Yuanxi's lost half of his legs were exposed in front of him. Fang Jifan was not polite and put the boots on, saying, "Don't be anxious, it will hurt a little at first."

He pushed the boot tightly upwards. Zhang Yuanxi's forehead suddenly felt cold sweat and gritted his teeth: "What... is this doing?"

The boots finally got stuck in Zhang Yuanxi's calf. Fang Jifan was sweating profusely and exhaled a breath of turbid air: "It's really not easy, it's heavy or not, come on, stand up."

Suddenly, Zhang Yuanxi understood something.

These heavy boots are...

He looked at his legs in disbelief. The boots were stuck on his calves, as if... his legs were still there.

He trembled: "I...I..."

Fang Jifan smiled and said, "Come and try it. If it doesn't work, let's change it again. Oh, I forgot. We have to fix it here to prevent it from falling off. After Fang Jifan said that, he made some trouble and fixed it firmly before he rudely helped Zhang Yuanxi up.

Zhang Yuanxi was still on the ground with one foot and hanging his other foot. He was a little frightened, but he was also a little expectant.

Why didn’t I think of this method at the beginning?

Subconsciously, he began to slowly lower his feet. The prosthetic limb disguised as a boot was a little heavy and landed on the ground with a thud.

Zhang Yuanxi's body trembled and he was afraid to leave.

Fang Jifan let him go, and he shook it before he could barely stabilize his body. He hesitated and slowly poured some strength into his injured feet. His body... gradually became balanced. Then, he gritted his teeth and slowly lifted the leg that was waiting for the prosthetic limb. The leg shook an arc in the air and finally... landed on the ground.

Actually... I can barely walk around.

Although it was awkward, heavy and difficult, but...

A hint of ecstasy flashed through Zhang Yuanxi's eyes, his face turned red, and the blue veins on his forehead were exposed. Then, he stepped out another leg, and the leg of the prosthetic could maintain balance. The other leg fell to the ground, and the prosthetic limb slowly raised, staggering and moving slowly. Although it was difficult to walk, he still limped, but at least... he could get rid of the crutches.

At this moment, Zhang Yuanxi's eyes turned red and tears were almost bursting out from his eyes.

I don’t need to use crutches anymore. I have been using this crutch for twenty years.

He continued to stagger excitedly, step by step, although he was not fast, he could not run fast. Even if he was walking, he had to be careful. His feet were heavy, like a feeding of lead. Fang Jifan's prosthetic limb was so rough that he could only do this step. But after all... he stood up, at least, the prosthetic limb was hidden under his skirt, at least... he could move barely.

Tears suddenly turned in Zhang Yuanxi's eyes.

Fang Jifan said with a smile: "Look, is this possible? As long as it succeeds, you can slowly improve it according to its shortcomings in the future."

Zhang Yuanxi's body suddenly lost his balance, and he fell down in response, just as he was about to hit the ground first.

Fang Jifan's face turned green immediately. Damn, this is really a tragedy.

But who knew that it was Zhang Yuanxi who knelt down on the ground with a thump, "Thank you, Uncle Shi."

Fang Jifan finally breathed a sigh of relief. It turned out that it was not a fall. It was shocking and terrible. Fang Jifan put his hand on his shoulder: "No need to thank you, your father and I are a friend of life and death, just a pair of boots, it's nothing. Do you believe it or not? The friendship between your father and me is willing to give it to me with your heart."
