Chen Yaotian quickly equipped his weapons and armor. He was seen wearing an iron helmet, sleeved armor, a long sword in his hand, and wind-controlling boots. His whole body was dark gold in color, he was very powerful, and he had a dragon shape around his waist.

The belt adds to the elegance.

Chen Yaotian walked back and forth twice, and after getting used to the armor, he placed the long sword horizontally with his right hand, pulled out a hair from his head and let it fall. When the hair floated to the blade of the sword, it was divided into two.

"Haha, this sword has reached the level of blowing hair and cutting off hair. It is really a magic weapon. If all the soldiers under my command can be equipped with such a weapon, they will be able to exert great power on the battlefield and be invincible. Ma Heng is worthy of being an outstanding successor of the Mohist family. His ability to cast iron is unparalleled.

People can compare." During this period, good things have caught up with him. He got promoted and made a fortune, his wife came to his door, his martial arts breakthrough, and now he has obtained a magic weapon. People are in high spirits when happy events happen, and Chen Yaotian always has a smile on his face recently.

"My lord, thank you. Without the meteorite you provided, I wouldn't have been able to build such a magical weapon." Ma Heng was praised by his lord, and he scratched his head honestly.

"You don't have to be modest. I've asked many famous iron masters for help before, but they couldn't even melt it, let alone cast it into weapons. Just based on this, you will be much better than them." Chen Yaotian continued.

Said: "I want each of my subordinates and generals to build a pair of weapons and armor. I wonder if the meteorites are enough?"

"Don't worry, my lord, the armor and weapon you are wearing uses less than one-tenth of the entire meteorite. It should be enough to build one weapon and armor for each person. It's just that meteorites are difficult to melt. I'm afraid it will take me a year to complete it alone.

"

"Is there any way to shorten the time?" Chen Yaotian asked aloud.

"There's basically no way, unless we can find a few people who have the same iron casting skills as me to help."

"How many people in the world have such skills as you! This is really troublesome." Chen Yaotian rubbed his forehead in embarrassment and sighed. Then he followed Ma Heng's words and said again: "What do you mean?

Just finding something that can raise the temperature in the furnace quickly can shorten the time it takes to cast iron?”

"Yes, I have been looking for this kind of thing. If it can be found, the iron casting technique will have a new breakthrough. The sharpness of the weapon will also reach a new level."

The sharpness of the weapon is inseparable from the temperature in the furnace when the iron is cast. The higher the temperature in the furnace, the cleaner the impurities in the iron can be removed. The fewer impurities, the higher the quality of the weapon.

"Have you ever heard of coal?" Chen Yaotian thought for a while and said.

"Excuse my ignorance, I have never heard of it. What is the use of this coal?"

"Coal is a black or dark brown mineral formed by ancient plants buried underground. Under conditions of airtightness or insufficient air, it has been subject to underground high temperature and pressure and has deteriorated over time. Compared with carbon, it can burn

Emit more heat." Chen Yaotian heard this and knew that coal had not been discovered in this era, so he explained to Ma Heng.

"Is there really such a thing in the world?" Ma Heng was half convinced.

"Well, I'll send someone out to search for it later. Once I find it, I'll give it a try and we'll know."

Ma Heng heard Chen Yaotian's affirmative answer and said excitedly: "If coal can really emit a lot of heat, I can guarantee that the weapons equipped by our Shanggu Army will be sharper than others."

"Okay, get busy first! I will send people to look for coal mines now. And then I will call Dian Wei and others to come, and you can build a pair of weapons and armor that suits them according to their wishes," Chen Yaotian said.

Only then did he and Xi Zhi exit the iron foundry.
