Su Hengqi was furious and was about to explode. Qin Xiqing hurriedly smoothed things over and said: "Brother Su, don't be angry, Mr. Fang can't speak. Everything is my fault. I will apologize to you. Let's leave now and never come back again." I'm disturbing you."

After that, Qin Xiqing hurriedly stepped forward and took Fang Zian's arm and walked out. Fang Zian laughed and let Qin Xiqing pull him away. As he walked, he counted in a low voice: "One, two, three, four... "

Before the word "five" came out, Su Heng shouted from behind: "Stop!"

Fang Zian smiled and whispered: "The five breaths haven't arrived yet."

"You came here to humiliate me for no reason and then left like this? That's unreasonable. Do you think I, Su Heng, am easy to bully? You must speak clearly before leaving today, otherwise, this matter will never end." Su Heng shouted loudly. .

Qin Xiqing turned around and said with a smile: "Brother Su..."

Su Hengdao: "Miss Qin, it's none of your business...I don't accept your apology."

Fang Zian also said almost at the same time: "Xiqing, no need to say more, this matter has nothing to do with you, it was me who scolded him."

Qin Xiqing was helpless, frowning as she looked at Fang Zian, who was extremely angry, and said angrily: "Just go ahead and make trouble, I shouldn't have brought you here."

Fang Zian didn't hear anything, and turned back to look at Su Hengdao: "Did I scold you wrongly? You have no ability, but you pretend to have ability. This is using fame and reputation to deceive the world. Shouldn't you scold you? If you really have it Prove it to me. If I scold you wrongly, I will kowtow to you and apologize. If you can't prove it, then I scolded you rightly. Not only will I scold you, but I will also publicize it after I leave. Expose the truth about your incompetence."

Su Hengqi's lungs exploded. He had never seen such a shameless person. Although he was just a craftsman, he had never been so humiliated in front of someone in his life.

"Very good, I will prove it to you. When the time comes, I want you to kowtow to me in front of many people in the market to apologize. Do you dare?" Su Heng said angrily.

Fang Zian laughed and said, "What are you afraid of? I'll admit it when I'm wrong. I'm afraid you don't have the ability. How can you prove it?"

Su Heng strode into the west wing, and soon moved out a wooden box, took out something from it and held it in his hand. Fang Zian and others saw clearly that it was actually a dark, palm-sized toad-like thing.

"What is this? Is it your son's toy? Hahaha." Fang Zian laughed.

"Look, you have never seen the world." Su Heng shouted coldly, stretched out his hand and twisted the iron rod on the side of the iron toad a few times, and then threw the iron toad on the ground. The iron toad paused on the ground. After a pause, he suddenly jumped up and jumped half a foot away. Then he jumped again, and another jump, seven or eight times in a row, and he jumped from the house to the back door and stopped there.

"Ah! Is that alive? How can it jump?" Qin Xiqing exclaimed.

Su Heng sneered: "What's the skill of living? It's all iron. That boy, is this a brilliant skill?"

Fang Zian was also surprised. This kind of thing would naturally be nothing in later generations. It was nothing more than a spring that was wound up and connected to a machine shaft to drive the movement.

The frog just jumps on its limbs. However, this was in the Song Dynasty. This thing not only involves the toughness of the steel used in the clockwork, but also the technology of the machine shaft and gear linkage, and the way the toad jumps is through the irregular crankshaft. If it is realized, it will not be simple.

"There are some tricks, but it's nothing. Let me guess, is there a thin steel coil with elasticity inside? After tightening it, it will automatically restore itself as soon as you let go, driving the gear plate and letting the iron toad's He stepped back and jumped up, right?" Fang Zian said.

Su Heng was a little surprised. The man in front of him actually understood the principle, which was really impressive. You must know that this thing seems simple, but few people really understand its principle, but this guy saw through it at a glance.

"You also have some skills! Okay, this is really nothing, then look at this."

Su Heng reached out and took out something about a foot long from the wooden box. After seeing it clearly, Qin Xiqing exclaimed and hid behind Fang Zian. Fang Zian also saw clearly what it was and said with a smile: "Don't be afraid, that is It’s just a fake centipede.”

It was indeed a centipede. Its body, which was about a foot long, was lifelike, and its whiskers and legs were made of thin iron rods. Centipedes are said to have hundreds of legs, but there are not so many centipedes. There are only about a dozen pairs of often arched legs. It's just iron legs. Each pair of legs is installed on a section of the body, and then connected together to form a whole.

"Look." Su Heng turned the knob placed on the top of the centipede's head seven or eight times, and the mechanical spring inside made a clicking sound. Then Su Heng placed the iron centipede on the ground and took away his hand. .The iron centipede started to move, shaking its head and tail, its long whiskers trembling, and ten pairs of long legs crawling on the ground. The connected body could actually turn one by one and crawled on the ground several times.

Fang Zian looked at all this in astonishment, and was filled with admiration. This iron centipede was obviously also driven by a mechanical spring, but it was ten or even a hundred times more complicated than the iron toad. The toad only needs to move back and bounce, and the iron centipede can But it requires all ten pairs of legs to crawl and move. This is not only the power of the mechanical spring, but also requires the linkage of the internal machinery, and the most difficult thing to achieve is to coordinate them all. If the centipede's long legs want to take steps, they also need to use When looking at the means of crankshaft traction, you can see that each long leg is connected by a hair-thin iron wire at the joint. Every time the centipede takes a step, it relies on this filament to generate force, using its internal The irregular crankshaft deflects it to fall forward, which is actually an extremely clever mechanical manufacturing method.

Fang Zian knew that he had found the right person. This Su Heng was by no means a person seeking fame, he was a real master, a real skilled craftsman. Of course, he had never really thought that he had no ability before, it was just a way of provoking generals. But Su Heng showed these two things, which was enough to shock Fang Zian.

"How? Does this count as something that can impress you?" Su Heng looked at Fang Zian's shocked look and sneered proudly.

Fang Zian stepped forward quickly, bowed his hands and said: "Master Su, I am reckless and blind to the superior, so I am convinced. I just admit defeat. If you go to a place where there are many people, I will kowtow to you and apologize. Accept. I will never break my promise if I accept defeat."

Qin Xiqing frowned and looked at Fang Zixin and said: I told you that Su Heng had extraordinary skills, but you didn't believe it. This would be embarrassing. If it's true.

It would really be a big joke to kowtow and apologize.

Su Heng sneered and waved his hands: "That's all, how can I argue with a young man like you? Young people, don't be so arbitrary and arrogant in your behavior, and don't hurt others with your words. You have never experienced many things in this world, how can you talk nonsense and attack others? Call you Be good, you've met me. If others don't give in, you might have to kneel down and kowtow on Zhonghe Street."

Fang Zian nodded and said: "What Master Su said is absolutely true. Fang Zian has learned from it. Thank you Master Su for your magnanimity. But... I would like to ask you, although Master Su made these iron toads and iron centipedes with precision, what is their practical use?" What's the value? A hoe can also be used to dig soil, and a sickle can be used to cut rice. What use are these two things apart from being used as toys for Mr. Ling to play with?"

Su Heng frowned and said: "This is skills and methods, this is the ingenuity and ability to make objects. What do you know? Practicality? I haven't thought about this yet."

Fang Zian said: "I don't mean anything else. What I mean is, if Master Su has such means, why not use them to make some practical things to benefit the public? Isn't it a pity to waste natural resources?"

Su Heng frowned and stared at Fang Zian without saying a word. Why didn't he have such regrets? But this kind of mechanical device is difficult to put into practice. What can the power of a coiled steel spring be used for? The force is not long-lasting and not strong, and many things are difficult. There was nothing he could do. This was actually where he struggled. But he really had no way to solve the matter.

"Master Su, I came to visit today to bring me something that allows Master Su to display his exquisite craftsmanship, and it is practical. I have an idea, and you, Master Su, have the skills and ability to make it. You and I will cooperate. It will shake the world. This is the original intention of my visit today. Those words before were just words of encouragement, and they are definitely not disrespectful to the master." Fang Zian said.

Su Heng frowned and was about to refuse, but after going around and around, he came up with something to do for him. Su Heng had refused before, so how could he agree now?

"Don't refuse first. Let me show it to you, and then you decide whether you are willing to help me. If you feel that you are still unwilling to help me, I will leave immediately and never come to bother you again. What do you think?" Fang Zian As he spoke, without waiting for Su Heng to speak, he placed the package he was carrying on the table, opened it, took out a large stack of drawings filled with structural parts, and unfolded them in front of Su Heng.

Although Su Heng didn't want to look at it, as a craftsman he was curious and had a desire to see what it was when he saw the strange figures, so he reached out to flip through the figures. Fang Zian quietly introduced the principles, structure and use of the work. The more Su Heng saw the distant view, the more surprised he became. The more he listened, the more he felt that this thing was exquisite, and his expression changed drastically.

"You mean, the power of steam can be used to push this thing to operate, replacing the power of manpower and mules and horses? Is the power of steam so powerful?" Su Heng finally asked this related question.
