On all kinds of delicacies, Suo Longtang, Haifu and others bombed in turn, including Bi Long, this buddy is the most shameless, talking about this orchid and the Mass, this is called an understanding, at first glance, it is an old driver.

There are two types of Mass knots: solo dances and group dances, with the solo dance focusing on the expression of the limbs.

The group dance, on the other hand, focuses more on the transmission of artistic conception, with thirteen people separated by the same distance, no more and no less from beginning to end, which symbolizes a kind of restraint.

No matter what you do, how you walk the stage, the distance between each person's left foot and the other person's left foot cannot be changed.

Under this kind of rule, if you can also put out a beautiful group dance, your skills can be seen.

Moreover, it is very ornamental.

Wu Cheng has never seen these bells and whistles, and this kind of on-site viewing is completely different from watching it in front of the computer.

Seeing that the heat was almost over, Haifu began to talk about it, "Second brother, last time I sent troops to send you to Zhongzhou Tianya Haige, how about you see my male division?"

Wu Cheng was in the mood to deal with him, and said casually, "It's not bad." ”

"It's true that if you can't see the second brother, the weapons of these soldiers are really unbearable, too brittle, and the quality of the iron is not good. ”

"Don't you have steel?"

Haifu and the others' eyes lit up, staring at Wu Cheng, coming, coming, Wu Cheng is going to be set!

Steel definitely has, albeit in smaller quantities, but there are also, but they need tougher metals!

This group of turtle suns lasted for a long time, and the final conclusion was to build a steel legion, eliminate the opponent's ordinary troops as quickly as possible, and then work together to kill the enemy's bloodline mutants.

The gap in armament is irreparable and the biggest trench between the troops.

"Steel can be refined, but the yield is so low that it can only be used on bows and arrows or blades, and there is no guarantee that all blades can have steel.

Moreover, it is still not hard enough. ”

"Low yields?"

Wu Cheng now focuses 70% of his energy on Orchid, and only 30% on Haifu.

In Wu Cheng's impression, it seems that he has seen it in a certain book that the main reason for the low output of steel seems to be that the furnace gas temperature cannot reach more than 1500.

Moreover, the steel of this era is only a superficial appearance, and there are too many impurities in it, which cannot be compared with modern steel, and it is not known how many grades are missing.

"Is it because the temperature is not enough?"

At this moment, Bi Long and the others all showed a wicked smile, since Wu Cheng had already asked the question, then there was a drama in this matter!

"That's right, it's because this temperature is so difficult to raise that the yield is pitiful!"

"Oh, this is easy to do, when the blower blows air into the furnace, remember to increase the distance to heat the air, and the temperature of the furnace gas can naturally go up quickly. ”

Bi Long has been in the logistics of the army all the year round, and he also knows a little about forging.

Wu regretted a little bit, and Bi Long instantly felt that his mouth suddenly opened, that's what happened!

Previously, in order to increase the temperature of the fire, it was necessary to manually blow air into it.

But in doing so, the temperature will not rise much, and all skilled craftsmen will not know what is going on.

After Wu Cheng dialed it a little, they instantly understood that it was because the air coming in was too cold.

According to Wu Cheng's assumption, it is only necessary to add a section of air into the channel, and use coke to heat the air on this channel, and the speed will increase rapidly.

I don't know when, Bi Long has already taken out a charcoal pen and carefully recorded every word Wu Cheng said.

Haifu poured Wu Cheng a full glass of wine again, and Wu Cheng saw that the orchids on the stage actually formed two rings, which were flexible and zizizi, and this angle was really good.

"Second brother, but the hardness of the steel is not enough, the warrior stabs straight with a knife, and it is also piercing, which is nothing more than a non-frontal attack. ”

This is actually an inevitable thing, such as can a helmet be bulletproof?

It stands to reason that a bullet can easily pass through a helmet, but not at an angle.

If it's a head-on impact, it's definitely chilling.

But as long as it deviates slightly, the bullet will slip away, and it will not penetrate at all.

It's the same thing with this armor.

Wu Cheng almost didn't think about it, and said casually, "Forge a few more times, forge the impurities in it, and add two pieces of meteorite iron to it." ”

Meteoric iron, in all kinds of martial arts, is a good material for forging weapons, what extraterrestrial meteoric iron, deep-sea meteoric iron.

In fact, it's all fucking bullshit, the reason why meteorite is endowed with all kinds of magical functions has something to do with its provenance.

In ancient times, before people invented iron tools, suddenly there would be extraterrestrial meteorites, note that this is a meteorite, not meteorite that reached the earth.

Some meteorites contain a large amount of metal, which is rubbed by the atmosphere and fused by the high temperature, turning it into a lump of metal and falling to the ground.

At that time, the emperor looked at it, this thing is good, I haven't seen it before, it's hard.

Everyone said how ignorant the ancients were, how self-contained, unenterprising, liking religion, and ignorant of science.

This is all nonsense, I like religion and mythology, that is the emperor in order to fool the people, solidify his rights, and make everyone think that the reason why the emperor is the emperor is arranged by God.

Who would dare to rebel against the chosen one arranged by God?

However, the ancients were not stupid, if it was useful to pray to God and worship Buddha, why should people be determined to win the sky.

All the gates are waiting for the opportunity to move, if the emperor is honest, I will let you continue to fool, if you are not honest, we will rise up and kill you.

Aren't you the chosen son, we like to be the chosen one, we like to be the chosen one, what bullshit religious gods and Buddhas, at this moment, no one believes it, people only believe in the butcher's knife in their hands.

So, to say this is to show one thing, the ancient people were not stupid, and they could even be said to be very smart.

When the ancient people of Huaxia discovered meteoric iron, pay attention to the fact that this is meteorite, not an unused meteorite.

They didn't treat meteorite as a gift from God, they bowed three times and bowed nine times a day, and the first thing that the ancients thought of was, is there such a thing on our earth!

What a great idea, the reason why iron tools were discovered, this is the root cause.

If this piece is offered, it will be fucked, and I don't know how many years later the iron artifacts of Huaxia Kingdom were discovered.

Even, the ancients made a preliminary analysis of this thing, and even dared to burn this piece of meteorite with fire, providing solid technical support for the smelting of iron ore.

They found that it conducts heat, and that it softens at a certain temperature, and found something similar in some ores.

Then the iron ore is calcined at a high temperature with coke, so that the molten iron in it flows out, the ore slag sinks, and the iron tool is born.
