Before the sword fighting in front of the palace begins, four swordsmen are built. This task is not light. First, there are quantity requirements, secondly, time requirements, and finally quality requirements. The four swords must be of equal level to demonstrate fairness.

But in this era without standardization and in this era of completely manual work, it is good to complete the four swords on time, and it is also necessary to have corresponding requirements for quality, which is too difficult.

The sword can be said to be a master of swordsmanship. If it cannot be copied, the quality will definitely not be too good. Therefore, the swordsman who accepts this task is under great pressure. He casts swordsmanship day and night, and his hair will fall out.

But it is still difficult to fulfill all the requirements. The two swords with similar appearances are completely different inside. There is always a difference between good and bad when chopping, so that the requirement of fairness cannot be achieved. Fairness is the most important thing. If the four swordsmen cannot make the duel fair duel duel duels duels duel, it is the responsibility of the sword-casting master.

Since you can't solve this problem yourself, you can only find someone in Linzi City who can solve the problem.

In Guan Zhong's front yard, Chunying's father was also considering how to forge four identical swords. He said to himself: "The temperature of the stove, the quality of the ore, and even the strength of the beaten swords will affect the quality of the swords. If there is a change in conditions, the forged swords will be very different. Even if the appearance is the same, there is a difference between clouds and mud inside. How can we make four good swords of equal quality at the same time?"

A good sword is not difficult, but the difficult thing is to repeatedly cast a good sword. After all, there is no standard, energy cannot be produced.

Simply put, it cannot be standardized casting.

During the Spring and Autumn Period and the Warring States Period, many famous swords emerged, such as Yu Yan, Juque, Gan Jiang, Mo Ye, Zhan Lu, etc., but there was only one of these famous swords, and it was not said that four swords of equal quality appeared at the same time.

In an era without standardization and conditional monitoring, this is even more difficult.

All sword-casters were thinking hard, including Chunying. She recalled the content of "Taigong Sword Record" and thought that the temperature of the stove could be solved by making a large stove. As long as the stove is large enough, four swords can be made in one stove, and the temperature of the flame will be no different.

The problem is the problem of ore and blacksmith's level. How to extract iron of a considerable quality? There is a record of melted iron juice in "Taigong Sword Record". If the ore is refined into iron juice, then the iron juice is divided into four parts, and the quality should be similar.

Then there is the method of pounding. It is definitely not possible to use your hands, but if you use a heavy object to fall at the same height, you can ensure that the weight of each hammer is the same.

This will solve the three problems of temperature, ore and pounding, and create four similar swords in one breath.

"Taigong Sword Record" begins by saying that regardless of talent, it is used according to the rules. It means to exclude the level of craftsmen and use objective conditions to enable any craftsman to refine a good sword.

Is pure strength not enough? It doesn’t matter. As long as I pull the heavy object to a certain height and fall, I don’t have to worry about the unstable force of the hammer. Ensure that the force of each hammer is similar. In "Taigong Sword Record", there is a comparison of weight and height, so I just draw a table and let someone follow the picture.

"I have a way." Chunying said excitedly. She could solve the problem that all swordsman in Linzi City could not solve, and this sense of accomplishment was unprecedented.

Xin Fang couldn't bear to hit Chunying when she saw her dancing, but she reminded her: "Even if you can solve the difficult problems that everyone is, you can't tell me. Don't forget your identity."

Chunying was poured with a basin of cold water, but she still had a smile on her face, as if the whole class could not solve the problem, and he could solve it alone. This sense of accomplishment was not easily eliminated. Although she could not share it with everyone, she was still happy. She said to Xin Fang: "I still have you, it's enough to share it with you."

Xin Fang was infected by this innocent and romantic girl and couldn't help but smile: "You, you are trapped in a cage, but you can still be so optimistic." You can clearly see the miserable future of her beautiful and white hair at a glance, and see the miserable ending, but Chunying can still make fun of her hardships, and she doesn't know if she is stupid or strong.

Looking at Chunying's innocent appearance, Xin Fang suddenly thought that maybe she could help Chunying. During this period, she had been learning sword dance, her body became lighter and could fly over the eaves and walls. Although I don't know if all dancers are like this, Xin Fang has indeed learned great skills.

"Tell me in detail how to solve the problem."

Chunying told the other party everything he learned from "Taigong Sword Record" that he could not leave the backyard, but sharing it with friends was also a kind of happiness.

After Xin Fang remembered the content, he found a silk scarf to cover his face, climbed over the wall and left the Prime Minister's Mansion, and came to the Sword Forging Hall.

At this time, the masters in the Sword Forging Hall were thinking hard. These Sword Forging Masters could not think of a standardized method of making swords and could not eliminate the variable factors.

At this time, a masked woman suddenly broke in with Xiangfeng, which scared several sword-casting masters.

"Who are you?" Although the sword-casting master is not a swordsman, he can fight, and there is no shortage of weapons here.

Xin Fang was also very nervous, but she pretended to be calm and said, "I am the sword slave of Taigong Sword Furnace. I came here to give advice to the mystery under the order of Taigong's descendant."

Taigong Sword Furnace? The successor of Taigong?

The sword-casting masters who stood in hand and stood up in preparation for war looked at each other. They naturally knew that Taigong must have referred to the founding king of Qi, Jiang Shang, Jiang Taigong. They just had never heard of Taigong sword furnace, nor did they hear of Taigong successors.

"What can you give me some advice?"

"I know you are now in a dilemma for creating four swords of equal quality at the same time. The descendant of Taigong has cracked the method of making swords and specially asked me to teach you." This is how Xin Fang helped Chunying. On the one hand, it can protect Chunying, and on the other hand, it can also promote Chunying's achievements. Chunying is indeed the descendant of Taigong, so Xin Fang did not brag.

"Please tell me." The sword-casters put down their weapons and were willing to listen to Xin Fang's methods.

So Xin Fang divided a furnace of four swords into three steps, divided into iron juice and hammered the heavy objects one by one. The sword-casting master was overjoyed and his doubts disappeared. The other party must be the sword slave of the descendant of Taigong. Who else could have thought of such a wonderful method except Taigong?

These three steps are not complicated, but it is not easy to think of this kind of thinking. The sword-casting masters may not even think of it. After the method is proposed, the sword-casting masters can understand it, which shows that there is no unfathomable point in the three steps, and the highlight is a problem of thinking.

"It's amazing, it's amazing!" The sword-casters knew that there was no problem with the four swords, because uncontrollable factors were solved, so they could create four swords with a very different size, and even a slight gap could be ignored.

When Xin Fang saw that the swordsman knew about it at once, he immediately went in and did not give them a chance to ask more questions.
