With a simple analysis, he found out the reason why the people of the Instrument Institute tried so hard but couldn't create the finished product they wanted - one of the materials was added incorrectly.

What the Instrument Academy intends to build is a long sword, and the basic material used is fine iron, which is commonly used in forging weapons.

This metal has good toughness, the price is not low, and the most important thing is that it is compatible with other metals and is not easy to conflict.

The choice of this metal as the base material is obviously also extremely important to this construction.

But the auxiliary materials they chose were red gold.

Red gold is a scarce metal and a valuable metal that has no price on the black market.

You can also see the intentions of the instrument institute from here, but if you want to create a sharp weapon with sharp attributes, it is wrong to use red gold.

Thinking like this, Yu Hua opened his mouth and said, "Elder Niu, Elder Liu, this red gold doesn't seem to be suitable for forging swords, right?"

Red gold has an amplifying effect on the release of the power of qi and blood, and is an excellent material, but its toughness and compatibility are not strong, and when combined with fine iron, it will weaken the characteristics of both sides.

That's why they haven't been able to succeed before.

Yu Hua was not a professional refiner, and he had never built weapons before, these were obtained from the data flow in his mind.

Hearing his words, everyone turned their heads to look at him, and Liu Chengxi asked: "Red gold has the effect of increasing the power of qi and blood, this is already the best metal we can find, if this doesn't work, we have no other way." ”

Suddenly, his painting style changed: "Boy, Lao Niu invited you to come, but I didn't let you make a mess, we only have this material for us, if you have a way to say it directly, just change the material." ”

Red gold was the best metal they could find, but they didn't consider whether it was the right combination.

Aren't they forging weapons with sharp characteristics?

He looked at the data flow in his mind, and it was a little strange, if he wanted to create a weapon with sharp characteristics, then he should also choose a metal with good toughness, and materials with amplification effects such as red gold were not the best choice at all.

The most suitable combination is fine iron and fine gold, both materials are based on toughness and sharpness, so that the desired effect can be forged.

Looking at the data stream, he wondered, it was obviously a very commonly used collocation, why did these refiners present selectively ignore it?

Yu Hua was incomprehensible, but he didn't get entangled, he was here to help, and if he could help himself, he naturally had to help, if he couldn't, he shouldn't be reluctant.

The others turned their heads away and ignored him, but Niu Mao noticed him.

"Boy, do you have other ideas, since you said that red gold is not suitable, then what materials should you choose?"

Faced with Niu Mao's question, Yu Hua thought about it and finally decided to give an answer.

He gave a simple picture of the data flow in his head.

Without waiting for Niu Mao to react, Liu Chengxi, who was concentrating on the side, spoke first, although he was engrossed in thinking about countermeasures, but he also paid a little attention to Hua, obviously he also had expectations for Hua.

"Pure iron and pure gold? this combination should not work, both are the strongest and toughest things, and ordinary refiners simply cannot control them.

With such materials, it is extremely difficult to forge sharp properties, even forging a finished product. ”

Is it because of insufficient workmanship?

Hearing Liu Chengxi's explanation, Yu Hua finally got it clear.

It's not that they didn't think of such a combination, it's that with their current process, they can't combine the two metals well.

However, it doesn't seem like a complicated process, does it?

He glanced at the data flow in his mind, and the process of forging using these two materials recorded above did not seem to be complicated.

According to the evaluation of the data flow, according to the specific steps, even if he is started, there is a certain chance of success!

Maybe there is some misunderstanding in this? Or maybe these are the right manufacturing processes in your mind?

Thinking like this, Yu Hua didn't say anything, he had done his best, and it was not appropriate to speak again.

Not only will it cause unnecessary trouble, but it will also easily expose the data flow in your mind and bring disaster to yourself.

His proposal seemed to remind Liu Chengxi.

The refiners were studying the forging plan on their own, and a disciple handed over a drawing.

Yu Hua took it, he was wondering, Liu Chengxi explained: "This is the formation that needs to be engraved on the weapon later, you take a closer look, maybe it really depends on you to build this time!"

An extremely complex formation was recorded on the drawings, and he watched cautiously for a moment as a stream of data emerged.

Sure enough, this pattern is a formation engraved on the weapon with sharp special effects.

There are many levels of weapons, and the best of them is the natal weapon. Created by the warriors themselves, the power is the strongest in the same level, and it has growth.

Secondly, there are some weapons engraved with formations, such weapons do not limit the owner, and the power is slightly weaker than the natal weapons, but the weapons with different formations have different power effects.

The second class is the standard weapon, if you can't find a suitable refiner to help build it, those martial arts students of the martial arts academy will only be able to get one standard weapon when they graduate.

The refiners who were discussing countermeasures seemed to have come to a conclusion, and they were ready to start refining.

The first is the wrought iron, which is the most basic and simple step, there is no skill at all, only the final forging number is qualified, and it is carried out by those disciples.

Liu Chengxi and Niu Mao watched from the sidelines, and the remaining teachers spoke out from time to time to give guidance.

"Boy, look at it, being able to participate in such a creation is something that ordinary refiners can't ask for!"

Yu Hua nodded, and he watched from the sidelines.

He also knows the matter of natal weapons, if he wants a powerful enough weapon, he will inevitably build it with his own hands in the future, and it is always good to learn some experience first.

Gathering the strength of the entire instrument courtyard, the progress of the construction of everyone was extremely fast, and after a while, the first process was completed.

This was followed by the smelting of red gold, as well as mixing.

This step is more difficult, and those ordinary disciples naturally can't help, so Liu Chengxi and Niu Mao, the two most skilled people, do it themselves.

"Boy, do you remember the drawings?"

Before going on the field, Liu Chengxi suddenly turned his head and asked.

Yu Hua thought about it, this pattern is not complicated, with the assistance of data flow, in a short time, he has already memorized it.

Without much thought, he nodded.

"Then you're ready, and next, it's probably really up to you!"

Leaving such a sentence, Liu Chengxi and Niu Mao played, leaving Yu Hua with a confused face.

What does he mean by that?

Do you want me to make the next inscription?

Are you kidding me?

Looking at the strange eyes of the disciples and teachers around him, he also realized that Liu Chengxi seemed to have given him a very important task.

It seems like this is the first time I've come to this institute, right? Is he doing this well?

However, seeing that Liu Chengxi had already concentrated on forging it, he could only hold back all kinds of doubts.
