Tie Armor tidied up his appearance and came to the door to open the door. Seeing Su Cheng standing at the door, Tie Armor looked up and down, then folded his hands and bowed.

"Iron armor in Jixia Academy, see the prince."

"You should see me the first time?"

"Yes, Tiejia met the prince in person for the first time. In Yandi, there may be many people who did not know, but not many people who did not know the prince. Tiejia did not first come to Yandi, so he could recognize the prince at a glance."

"Okay, then I will go straight to the point. Do you think you know the secret method of steelmaking?"

"Of course!"

"Do you know what the secret method of steelmaking is?"

"The secret method of steelmaking is inherited from the weapon refiner of the Immortal Sect, and is one of the skills of the Immortal Trail. But the prince should also know that even if the secret method of steelmaking is inherited from the weapon refiner of the Immortal Sect, the content of the secret method is different. As long as the secret method is different, he will naturally not be held accountable by the weapon refiner of the Immortal Sect. Please rest assured about this."

"If it weren't for the inheritance lineage, you wouldn't have obtained the inheritance of that lineage. Iron armor, what kind of steelmaking method do you master?"

"This method is four removals, two removals, and two adjustments. The so-called four removals are decarbonization, desulfurization, dephosphorization and deoxygenation. The two removals are to remove harmful gases and harmful impurities. The two adjustments are to adjust the temperature of the steel and adjust the alloy material composition.

Iron is a qualified steel ingot through these four methods.”

How could Su Cheng understand these things? He just felt unaware of it. In fact, he couldn't understand a word, but from Tie Arm's expression and tone, it can be seen that Tie Arm is confident.

"Mr. Tie, I don't understand what you said, but how long will it take if Mr. Tie makes a piece of steel?"

"It depends on whether the prince looks like a proof or mass production."

"Proofing and mass production? What's the solution?"

"Production means that the grass-cup produces a small part of the samples for the prince to see, but mass production is different from proofing. Mass production requires a complete production line, and the workers need to be trained, and mass production can be carried out at least one month before mass production. If the proofing is performed, I can produce steel in just one day."

"Mr. Tie will make a move first. Please!"

"Even if you want to make a proof, the prince should prepare the materials first." As he said that, Tiejiang took out a piece of paper and handed it to Su Cheng, "Try to match the things on it."

"What can... what? Popcorn stove? Mr. Iron, what's the use?"

"A very critical prop is needed to make steel, called a converter, which is used to replace converter."

"Oh, I will order people to deliver this list without stopping. Mr. Tie, my carriage is below, please get on!"

"Please, please!"

"By the way, Prince, I heard that there is a master of the Yan Palace who is proficient in the true qi of the ice?" Tiejia asked suddenly.

"Iron Armor asks about what Han Bing's true energy does?"

"Because in the proofing process, you may need to use a master who is proficient in the ice true qi."

"What level do you need to practice?"

“The seventh floor is good.”

"That happens that my king's ice true energy has been cultivated to the ninth level and should be available."

"It's so good that Caomin has a 10% more confidence in the success of the proofing." Tiejia laughed.

"Mr. Iron Armor is a little sure?"

"Ninety percent!"

Su Cheng's heart trembled and he couldn't help but look at Tie Armor.

Until now, Su Cheng has not felt the abnormality of the iron armor. From the first sight to the present, he has neither humble nor arrogant nor confident, and has not shown any humility in his conversation or expression.

This made Su Cheng's judgment on the authenticity of the Iron Armor continue to rise. When he first met, Su Cheng only reported 10% of his hope, and by the time he talked with the Iron Armor, it had already reached 50%. Now, Su Cheng suddenly felt that the one in front of him might have mastered the secret technique of steelmaking, and the hope value reached 70%.

The secret technique of steelmaking is self-evident to Yandi. Even without the matter of the Yunwang Mansion, the secret technique of steelmaking is a dream that Yandi wants to see but is out of reach.

Yandi Heishan produces a large number of iron ingots, but the price of iron ingots is a hundred times different from that of steel ingots. Yandi has been refining iron for so many years, but he is always making wedding dresses for others. The Yunwang Mansion has almost plundered a lot of wealth by making money by making money.

It’s okay to add to the trouble to the surrounding forces, and use the steel ingot outlet to pinch others’ throats. And you have to use it. Others have used steel weapons, but you are still using iron weapons. When you fight together, don’t you stretch your neck over and let someone cut it?

The gap between iron and steel is the difference in magnitude. Iron has neither the hardness of steel nor is it more brittle. When it comes to a steel knife, it breaks as soon as it touches it. This is the crushing of the weapon.

The carriage drove for more than an hour and came to the Ordnance Production Shop. The Ordnance Production Shop is one of the most important institutions of the Yanwang Mansion and is the arsenal of the 150,000 Yanwang Army in the entire army. There are 20,000 elite soldiers guarding the periphery, ensuring that no bird can fly in.

Entering the ordnance production workshop, Su Cheng led the iron armor to the iron smelting workshop. At this time, the items on the iron armor list have been purchased and all are spread on the open space of the workshop in turn.

"Mr. Iron Armor, look, are you buying it right? "

Iron armor stepped forward and swept it all, and checked it one by one, "Okay, that's OK, let's burn out a furnace of molten iron first."

In the iron smelting workshop, the iron is always available, and the iron is almost completed when the iron armor order is issued.

Introducing molten iron into the converter of popcorn, the following step is the most critical step in steelmaking. Remove the carbon sulfur scale oxygen, traditional simplified steel is to continuously forge and discharge these impurities. Not only is the workload large, but it also takes an extremely long time.

It is easy to use a converter. By rotating the converter, the molten iron is always in a flowing state.

"Prince, use the ice true energy to create a ball of water."

Su Cheng didn't dare to hesitate when he heard this. The shadow guard around him looked confused. He even had to use the ice true energy to refine steel? He had a bit of the style of an alchemist.

Soon, between Su Cheng's one hand, a ball of water rippled slightly, but it seemed to be water, but it was extremely cold. The ball of water radiated violently with white smoke and the fairy aura rose.

"Prince, hold on and wait until the white smoke evaporates clean."

Not long after, the water ball compressed to the size of an egg, and the nitrogen in it had been evaporated, and the remaining ball was pure liquid oxygen.

Blow oxygen into the stirred molten iron and mix thoroughly. Chemical reaction impurities will automatically float out when they produce thio, carbon, etc. in the molten iron.

"Prince, control this ball of ice real liquid to add it to the converter bit by bit."

Su Cheng also fought hard, and didn't care whether there was any danger or not. He followed the instructions of the iron armor. Drops of extremely cold liquid oxygen dripped, and then instantly vaporized into oxygen when the high temperature of the iron. The oxygen fused with the stirred iron, and the impurities in the iron floated out to the naked eye.

After a long time, the iron armor stopped rotating the converter and then cleaned out the impurities floating on the iron. This step is to remove harmful substances and remove impurities. The rest is to control the temperature of the molten steel and debug the alloy composition of the steel.

With concentration, time passed quietly, and before I knew it, two hours had passed.

"Okay, the debugging is completed. The sample can be produced just when the steel ingots cool down." Iron armor took out the molten steel and poured it into the template and smiled easily.

"It's easy to do, put the template on the water to speed up cooling."

"No, the cooling process requires natural cooling. The sudden drop in temperature will affect the structure of the steel and make the steel brittle and brittle." Tie Arc hurriedly reminded.

"Prince, the lunch has been hot three times. Should I eat it?"

"No hurry, wait until the sample comes out before eating."

"No hurry, the sample is almost out after the meal." Tie armor suddenly said, causing the expressions of the several shadow positions around him to change suddenly.

So far, no one has refuted Su Cheng's words in front of Su Cheng. But no one expected that Su Cheng's face had not changed for a moment, and he laughed.

"Mr. Tie is right. Here, Mr. Tie is the biggest. He says whatever he says. Everyone is hungry and have a meal!"

On the other hand, Su Mu was also urged by Mo Lan several times. Although Su Mu was sure of the success rate of this steelmaking, he had no results after all, and he was uneasy. Even with the secret book of Han Ice True Qi in his hand, Su Mu was not in the mood to read a word.

After four days of traveling, the fortune of luck will be converted into life span is about five months. From the previous month's life span to the current half year's life span, the harvest is huge. The long river continues to encourage Su Mu to exchange it. As long as the exchange can reduce the time of cultivation, it can directly achieve growth. But it is only half a year's life span, and even if it is exchanged a little, it is directly threatened with life. Su Mu is waiting for this time to successfully refine steel, and I think his fortune will not be less this time.

"Molan, have a meal!"

"yes."

After dinner, Su Cheng and his group couldn't wait to come to the Iron Smelting Floor. Ying Tai carefully took out the steel material from the mold, and the iron material with a slightly black black flashing cold light appeared in front of the few people.

Su Cheng's eyes flashed with brilliance, and he stretched out his fingers and tapped the steel with an intoxicated look. Hearing the beautiful sound, just looking at the color, this is definitely good iron, and there is no conclusion on whether it is steel.

There is no professional detection method for judging whether it is good steel. The only way is to use a steel knife to cut it. If you cut it down, the steel knife will be fine. If you cut it down, it will definitely be iron. If you cut it down, both sides will suffer losses. That is almost a good steel.

Su Cheng pulled out the Shadow Guard's sword with a bang, and slashed it like lightning.

when--

With a loud bang, the steel knife broke in response to the sound, and the broken half blade soared into the sky and inserted straight onto the beam above the head.

Everyone looked at the steel ingot with a hot look. There was only a shallow knife mark above the steel ingot, as thin as hair, almost invisible.

It can be seen that the mass of this steel material is much higher than that of the steel knife material of the impact position.

"Okay, good steel, it's good steel... Hahaha... Mr. Tie, please accept my benefactor. You are really my benefactor. I thank you. I will give you 150,000 soldiers of the Yan King's Army. Thank you Mr. Tie."

"Your Majesty must not be done. With all the skills of iron armor, you just want to have a place to use it. If you can help the Youth Prince, it would be a blessing for the people in their lives."

"Okay, great. From now on, I, Yan Di, will no longer have to be pinched by the Yunwang Mansion. Mr. Tie, how long does it take to mass-produce steel and how many kilograms of steel can be produced each year?"

"Building a production workshop requires rebuilding production equipment. It takes as soon as one workshop from construction to completion. And the output after official mass production... can reach a daily output of 1,000 pounds."

"Annual production...wait, Mr. Tie, are you not kidding? Are you talking about... a thousand pounds per day?"

"It's not too much for a thousand pounds per day. As long as the equipment is enough, the output is unlimited."

"Nighty pounds per day...Nighty pounds per day..."

At this moment, Sucheng could not listen to other words about Iron Armor. His mind was full of Nissan jin. What is this concept? Nissan jin means that his production speed is more than ten times that of Yunzhong Zhuan Tianfu. In one month, he can not only be self-sufficient, but also sell more. In addition, steel will become as cheap as iron in the future.
