technical type

Early the next morning, while eating, Ji Mo felt something different. Aunt Ji's attire today was very different, not that kind of long-sleeved shirt, and even the string of rosary beads wrapped around her wrist, which she never left her hand, was nowhere to be seen. Without a trace, the bright yellow tassel between the cuffs seems to have lost some of the dazzling brilliance, making it more elegant.

The cuffs of the cool-toned clothes were tightened, and the clothes, together with them, were less flamboyant and looser, and more slim, highlighting Aunt Ji's not bloated figure.

After the meal, Ji Mo got up to leave, and Aunt Ji also got up, Ji Mo looked sideways in surprise: "Auntie wants to go out with me?"

"Well, let's go."

Aunt Ji simply agreed and walked side by side with Ji Mo.

Three years ago, Ji Mo stopped his lessons with Mr. Zhao in the morning and devoted himself to learning swordsmithing. He went to the swordsmithing room every day. When he walked in this direction, there was only this road, and there was nothing nearby. There are no other courtyards. Seeing Aunt Ji walking the same road with him, Ji Mo asked belatedly, "Auntie is going to teach me how to make a sword today?"

"Just take a look. If you haven't read it for many years, you've already forgotten."

Aunt Ji refused to admit that she meant to teach Ji Mo. Even the after-dinner chats in the past had increased Ji Mo's professional knowledge, but she only said that it was small talk, which seemed to be related to sword casting, but it didn't seem to have anything to do with it. Big, it can be classified as anecdotes related to swords and the like.

Ji Mo didn't know why she was like this, but respected her approach, and never forced the other party to teach in person, which made Aunt Ji, the master, a bit of a name. No, this name was only recognized by the system. In the eyes of everyone, Ji Mo learned The master of sword casting is only Master Kong.

"Okay, then aunt just watch me forge the sword."

Ji Mo said so, and he already thought in his heart that if Aunt Ji saw something inappropriate, she would definitely tell herself, and she was no different from a guide.

Regarding this epee, because the name of the famous sword was determined first, Ji Mo really wanted to reproduce this famous sword when choosing materials, so he couldn't completely follow the several adjustment formulas given by Master Kong. To do, he needs to make his own innovations on top of this.

Unlike Feihong, which only adds a touch of crimson, Juque, the direction he hopes to achieve is blunt and heavy, hard and hard, all of which need to use ores with similar effects, sacrificing flexibility and flexibility to achieve epee This is where Juque lacks.

Ji Mo had never paid attention to sword casting in modern times. The so-called famous swords only knew a few names that the general public knew. Only when you know the difficulty.

Fortunately, the clay model is still easy to make. After confirming the approximate shape, Ji Mo glanced at Aunt Ji, but the other party said nothing.

Soon I put most of my energy on the selection of ores, not only to choose the ores with the right utility, but also to determine the ratio between each.

It’s not that you can’t just use one type, but it’s hard to say what’s perfect for one type. Alloys are better than pure iron. This is Ji Mo’s impression. He also hopes to complete a famous sword that is higher than ordinary iron swords. , so it is necessary to carefully consider the ratio.

Choose the advantages of the selected ore and discard its disadvantages to achieve a perfect complementarity, so that the forged sword can withstand the wind and rain and stand the test of time.

In detail, I told Aunt Ji, who was sitting silently beside me, about my tendency to choose ore, and about the ratio I had thought about, and asked Aunt Ji for her opinion.

"You can try slowly."

When Aunt Ji said this, she seemed to be encouraging.

Ji Mo understands, and it seems that there are still some problems, but for a while, it is not clear which aspect is more and which aspect is less, these all need experience, maybe Master Kong will say it directly when he is there, but Aunt Ji Obviously not.

"Okay, I'll try slowly."

Ji Mo thought about it again, and added and subtracted a few things. This time, he was going to experiment. The so-called sword casting technique, besides the almost fixed process, the most important thing is the adjustment ratio of materials. In this respect However, it is impossible for Master Kong to teach him everything, he always needs to innovate by himself.

Taking a step independently is like a child who takes the first step without the support of an adult. Ji Mo may stumble without the child's foresight, but he will not be afraid to take a step forward, and he knows the direction he is heading. In this way, every time Every step will be firm.

Since it is a trial production, there is no need to sacrifice the sword after smelting. It could have saved the preparation of cattle and sheep, but Ji Mo still prepared a few pieces of meat and put them in at the last moment. During the process of this experiment, he also chose a The adjustment ratio taught by Master Kong has tried the similarities and differences between adding meat and not adding meat.

The comparison of this kind of experiment is actually not obvious, but Aunt Ji's eyes are fixed, she can find the difference in the subtleties, the sharpness is different.

Ji Mo also discovered it after Aunt Ji pointed it out, and his eyes lit up, "Auntie, does this mean that only meat can be used, and it doesn't even need to be cattle or sheep?"

In ancient society, cattle and sheep were also very expensive. The most expensive thing was cattle. They were indispensable for plowing the fields and pulling carts. It was a crime to slaughter them lightly.

Ji Mo heard from Mr. Zhao that the price of a few slaves was equivalent to that of a cow. In other words, considering the cost, it is the most cost-effective to use human beings for sacrificial swords.

Human life is not as valuable as a cow. This situation is also thought-provoking.

Aunt Ji pursed her lips and remained silent. This conclusion was contrary to what she had been taught, and it was also not an acceptable point of view at the moment. She couldn't agree with it, and it was impossible for her to turn a blind eye to the result before her. In the end, she just said a word Not sent.

Even so, Ji Mo was greatly encouraged. He thought about the reason. Is the purpose of sacrificing the sword to please ghosts and gods?Is it to increase the fierceness?This mysterious statement cannot be verified, but there is one conclusion drawn by the swordsmith, that the sword made after the human sacrifice will be sharper.

So, what is the reason for this sharpness?If meat can also increase the same sharpness, what kind of change will be produced when meat is added to the fire?

"Ah, oil, it's grease!"

After careful analysis, Ji Mo suddenly realized that this has the same effect as a combustion accelerant. The current temperature of the fire may be a little worse, but with the grease falling into the metal solution, it will make them burn more fully and fuse together. It is more closely related, which probably has a similar meaning.

If you want to say that human sacrifice is better... What is more than flesh in human beings, it is bones. Then, what role do bones play in this combustion-supporting process?

Ji Mo remembered that there was a kind of porcelain called bone china, which was said to be made by firing cow bone powder. If bone powder could do this, could it be the same for human bones? The characteristics of it are integrated into it, whether it is fragile, smooth or bright, or other characteristics?

This conjecture is worth trying.

In the days that followed, Ji Mo was not in a hurry to forge the second sword, but seriously thought about this issue. Every time he had an idea, Ji Mo would write it down, and at the same time, he would also write down the order of the weight of the materials put in each time, the number of days of burning, And the addition of combustion-supporting substances, and the results obtained after adding animal meat and bones, and adding no meat, no bones, and neither adding bones nor meat.

Even if some of the sword-casting process is omitted, it is necessary to complete the repair and sharpening before the comparison can be made more clearly.During this process, Ji Mo was a bit short-handed, and each experiment took a long time, mainly because the smelting of ore did not happen overnight.

For this reason, the sword casting room was rebuilt again, the rooms on both sides were opened up, and two shaft furnaces were added. Ji Mo made Baishi and the two sword slaves a group, and made the other three sword slaves a second group. , I took the remaining two sword slaves as the first group, a total of three groups, at the same time, three shaft furnaces were fired and smelted, and three different experiments were carried out.

The first thing Ji Mo rejected was the method of adding nothing. The sword cast in this way does not look much different on the surface. It's clear at a glance.

Therefore, this one was eliminated first, and the advantages and disadvantages of the remaining three methods are not obvious. Ji Mo repeatedly examined, and under the same formula, the swords cast by three different methods, only this one step is different, seems to be the same. There are no obvious changes that can be seen at a glance.

The way swords collide with each other will also be affected by some other factors, such as the timing of quenching, the deviation in repairing, or even the strength of the sword holder when exerting force. Draw a completely objective conclusion without error.

Ji Mo presented the three long swords without hilts and scabbards in front of Aunt Ji, and said earnestly, "Auntie, please comment."

The same shape, the same material, the same heat, only the flesh and blood added after smelting is different, just adding, no specific changes in the weight have been made, that is the content that needs to be carried out in the next step.

It's just that, the three swords wrapped around the stems with cloth strips of different colors are also shining with cold light, and it is completely impossible to distinguish good from bad with the naked eye.

Aunt Ji picked up one and looked at it carefully. From the spine to the blade, and then from the blade to the blade, she saw the tip of the sword. She gently slid her fingers over it, touched it with her fingertips, and gently touched it with her nails. Tried the sharpness of the blade, judged by the gaps on the nails...

The second sword, the third sword, and the three swords were all looked at in the same way in turn, meticulously. After reading all of them, Aunt Ji was silent for a long time.

Ji Mo waited patiently at the side, looking back and forth between Aunt Ji and the long sword, hoping to get an answer. Based on Aunt Ji's experience, she should give him an answer that is enough to clear his mind.

"Your sword casting skills... are already very good."
