The coal smiths in the Baihui Gate have said that the coal is divided into seven grades, and the worst is loose coal.

The craftsmen of Daqin of this level of peat could not distinguish between good and bad coal by the intensity of the burning flame, and the best coal was called mirror coal, which was hard and bright, and some of them also showed human figures.

Bai Hui didn't know much about coal, but he knew that black and shiny coal without smoke was definitely better than brown and brown coal, and it was worse with smoke.

For a full hour, the craftsmen beside Bai Hui adjusted the stove.

"Zuo Shu is long, and the furnace temperature has reached the highest."

"Let's go." After Bai Hui gave an order, four strong men stood in front of the huge bellows and waited for Bai Hui's order.

Bai Hui believes that the temperature of this furnace should be close to 1,500 degrees.

Bai Hui picked up a bronze jue (Warring States wine utensils) and threw it into the furnace in front of Han Ji, and at a speed that was almost visible to the naked eye, the bronze jue turned into copper water.

The melting temperature of copper is only 1,000 degrees, not to mention that the bronze jue is still an alloy copper mixed with tin.

Bai Hui watched the bronze lord melt and then turned to look at Han Ji: "Gongzi has iron tools." ”

Han Ji was already stunned, and Bai Hui called him to come back to his senses, when had he ever seen such a violent flame. Hearing Bai Hui ask him, he stretched out his hand to the guard: "Your short knife." ”

Han Zai-gungoku is not one of the countries with the highest research technology in ironmaking.

An iron short knife was handed to Bai Hui.

Bai Hui tried the blade and threw it into the furnace and waved his hand gently, and the two strong men began to pull the bellows hard, and the temperature in the furnace soared again, and the high temperature made Han Ji take a step back.

The craftsman beside Bai Hui brought a blazing suit to block Bai Hui and Han Ji in front of him.

This fiery suit is a kind of use of asbestos in the pre-Qin period, and the clothes made of asbestos are better than ordinary clothes worn by people who work in front of the stove.

The firelight reflected Han Ji's face red, and the short knife quickly turned red, and then began to melt slowly.

Han Ji shouted violently at this time: "Fetch the iron stone." ”

Bai Hui nodded slightly at the craftsman, who ordered to suppress the fire and temporarily weaken the flames of the furnace. And when they are not paying attention, they will add high-quality coal mixed with coke to the furnace.

Soon, a basket of crushed iron ore was sent in.

The iron-making process of the pre-Qin era relied on charcoal, and the furnace temperature was not enough, so the items like sponges were smelted and then turned into iron through continuous beating.

The hidden coke was added to the furnace of fine coal to burn the iron ore and crush it, and the molten iron flowed into the furnace.

This is not a furnace for professional steelmaking, and there is no way to collect molten iron.

But the effect was achieved, and what Bai Hui wanted Han Ji to see was the temperature of the furnace.

The craftsmen stopped the furnace, cleaned the chamber, and smashed out the solidified iron bars that flowed into the furnace and sent them to Bai Hui.

Han Ji bowed: "Please general." ”

"Don't worry, please look at one more thing."

A honeycomb coal stove has already lit a fire, a small copper plate is being placed on it, and the water is slowly heating up.

Bai Hui then ordered someone to put the sample of coal on a tray covered with silk and held it in front of Han Ji.

"This thing was called Heidan in ancient times, and I changed my name to call it coal. Coal is divided into seven grades, the best coal is called mirror coal, the worst is peat, and the lower third grade coal is made into briquettes, which can be used by the people for fire heating. And the high-quality coal, Hedong 10,000 catties of coal is afraid of less than one catty. ”

Han Ji didn't care about the coal black, grabbed a piece of mirror coal and looked at it repeatedly, and said to himself: "According to the general's words, this thing is one out of ten thousand, and it is where the coal is refined." ”

"No, it's the quality of the mine. This is also the reason why I think of Fencheng, my people have found high-quality coal mines in the south, north and west of Fencheng, it can be said that nine catties of ten catties of coal are high-grade coal, and at least two catties are mirror coal. ”

"Gongzi thinks that this thing, in the next ten years, will make a Fencheng comparable to Taoyi."

Bai Hui's Taoyi is not only a pottery production area, it can be said to be the core city of commerce in the Central Plains, and most of the merchants of the Seven Kingdoms will pass through Taoyi, driving the local commercial level.

Seeing that Han Ji couldn't put it down while holding the piece of coal, Bai Hui knew that he was halfway there.

Bai Hui said: "Qin and Han sent troops to Fencheng together. ”

"No!" Han Ji refused.

This rejection of Bai Hui was not unexpected, Han would not be at war with Wei, so it was impossible to attack Wei.

Han Qi said: "I, Han, can share the Fencheng Coal Mine with Wei. ”

Hahaha!

Bai Hui laughed loudly, just laughing, but didn't say a word.

Han Zhi was extremely embarrassed by Bai Hui's laughter, there was one thing he knew very well, Bai Hui dared to say it, dared to use it to distribute Fencheng with him, and he definitely held it.

If Han and Wei join forces to develop the Fencheng coal mine, Bai Hui, who is close at hand, will definitely raise troops to fight.

Even if there is no war, troops will be sent to constantly harass it, so that it is impossible for the coal mine to produce at all, so the only object of cooperation is Qin and South Korea.

Suddenly, Han Ji reacted: "You, what you want is not Fencheng." ”

Bai Hui smiled and asked: "What do you mean by what Childe said, what I want is not Fencheng or there?" ”

Han Ji said word by word: "It's the entire Hedong County." ”

Bai Hui lightly high-fived: "Gongzi is really wise, it is true, it can be said that half of the county east of the Fen River in the entire Hedong County lies on the coal mine, and there are coal mines in Bancheng, Anyi and other places, strictly speaking, I want half of Hedong County south of the Fen River, I don't know about the north of the Fen River, maybe there is, maybe not." ”

Han Ji shook his head after thinking about Bai Hui's words very seriously: "Han, you can't send troops. ”

Bai Hui immediately said: "Since it is cooperation, it's not that I, Daqin, have done all the work, and the Han people just come to pick up the cheap, this is impossible." Therefore, it doesn't matter if you can't send troops, it's okay to give ordnance and rations. ”

Hearing Bai Hui's conditions, Han Ji still shook his head.

This time, without waiting for Bai Hui to say anything, Han Ji said: "In this way, I will report to my father and summon the important ministers to give the general an answer after the secret discussion." ”

"Okay, wait for the good news of the son."

Bai Hui no longer asked, such a big matter is not something that a son can decide, this is a real national matter.

Han Ji went back to report to King Han, and Bai Hui also closed the door to discuss.

"What do you think, will King Han agree to this matter?"

Gongsun Long asked rhetorically: "Then it depends on what the general wants, if it is just a Fencheng, or Hedong County with the Fen River, I am afraid that King Han will not agree." But if the general wants the whole of Hedong, plus the Wu Sui of the Han people, then the king of Han will definitely agree. ”

Gongsun Long turned over the words and stunned Bai Hui, how can the more you want, the easier it is to succeed.

Without waiting for Bai Hui to ask, Sima Jin jumped out: "Could it be that Mr. Gongsun is a fool to be the king of Han?" ”
