The butler of China and the Ministry of Rigude blushed and had thick necks, and they stood there and did not dare to say anything.

Bala Toast stood up and walked back and forth a few steps and said, "This is the end of the matter of Bilage, and no one is allowed to mention it." I think Mr. Ou will take his place, and the most important thing at the moment is to burn the charcoal out immediately, and time waits for no one. From today onwards, Mr. Ou is solely responsible for forging weapons, and you must listen to his dispatch and make extraneous branches, don't blame me for being unkind. ”

Bala Toast was really angry this time, and Bilegg gave him a resounding slap in the face, and he had to swallow his teeth in the stomach, which was uncomfortable. However, he also began to look at Ou Xuzi differently, no matter how he calculated, Ou Xuzi was really his nobleman, paving the ladder for him to go straight to the top in the future, Bala Tusi seemed to see himself praised by the emperor in the palace, full of brocade clothes, officials and ministers.

It all depends on whether Ou Xuzi can forge a treasure blade.

Charcoal burning is the burning of tree branches into charcoal. In the Book of Wei and the Chronicles of Punishment, it is vividly described that "in Jin, the rich people burn charcoal in the mountains, and the poor are in the prison." ”

After the Yuan Dynasty set up the capital of Beijing, the "Charcoal Bureau" was set up under the Zhan Academy, which was responsible for managing the affairs of salary, charcoal burning and charcoal distribution. The firewood and charcoal in the city's energy mainly come from the forests in the surrounding areas.

The method used for charcoal burning is the earthen kiln firing method. It is a direct heating method of fuel, that is, the heat generated by the combustion of fuel at the kiln mouth rises to the top of the kiln and spreads into the kiln. The flue gas circulates and flows, the heat and temperature of each point are basically uniform, and the carbonization and refining stages are completed to obtain charcoal with dense structure.

The charcoal kiln is generally 4 meters long, 2 meters wide, 2 meters deep, can be loaded with about 10,000 pounds of charcoal wood, can make 2,000 pounds of good charcoal, the charcoal workers will transport back the spruce tree into more than one meter long, the diameter of ten centimeters of firewood first cooled into dry firewood, at the bottom of the pit along the long surface parallel splicing paved two firewood, and then the prepared firewood sticks are placed horizontally on the bottom of the pit pad firewood, the bottom layer is loaded with small diameter dry firewood, the middle layer is loaded with semi-dry firewood, and the upper layer is loaded with live, wet firewood with a larger diameter.

Moreover, the firewood sticks should be tightened, and the short sections of the firewood sticks should be placed in the bent firewood section, so that there is no gap.

Renci returned to Tusi Mansion, and Ou Xuzi immediately greeted him and said, "Brother Renci, why did you come here before your body recovered, I am uneasy." ”

Renci said with a smile: "Brother Ou, I am a good charcoal burner, I burned charcoal for the official kiln of the Great Song Dynasty in my early years, and it is extremely important to cast charcoal for weapons, so I should burn it myself." ”

What else can Ou Xuzi say?

Renji was very careful and stubborn, he carefully inspected the charcoal kiln, the four walls were loose and patted firmly, the bottom drain pipe also looked and looked, before igniting the fire, cover the surface of the firewood stick with a layer of leaves, palm leaves and other covers, and then cover the surface with a layer of soil about 20 cm thick, and spray the appropriate amount of water and gently pat it with a wooden stick to make it sticky, so as not to let the soil block the fire door and chimney passage.

As soon as he was ready, Bala Tusi came with the China butler and the centurion Rigude, first pretending to greet Renji's physical condition, and then said to Ou Xuzi: "Mr. Ou, it takes 6 to 7 days to burn charcoal, and you are also very hard, you can go home to see your wife and children, and if you need anything, just ask." ”

Ou Xuzi expressed his gratitude.

Ou Xuzi had to wait until the charcoal cellar was lit before leaving, Renci loaded the dry firewood and grass at the bottom of the fire door, and then said to Ou Xuzi with a few pieces of dry firewood: "Brother Ou, you have to light this fire."

Ou Xuzi shook his head and said, "Just let Lord Tusi come, is he the master here after all?" “

Bala Toast, who was standing on the side, was very happy, Ou Xuzi gave it face, and he had to excuse himself and was stopped by Ou Xuzi, Bala Toast lit the fire and put it into the bottom of the fire door to ignite the firewood and grass, and after a while, it burned alive, and mercifully closed the fire door, and then covered the soil and sealed it, so that the white smoke was discharged from the chimney hole, so that the firewood in the kiln burned slowly and carbonized.

It takes at least 10 days for the official charcoal to be released.

Taking advantage of this time, Ou Xuzi is ready to go home and reunite with his wife and children, they always get together less and leave more, Xiao Xuanhan has never complained, but she looks forward to her husband and watches at the door every day, hoping that her husband can come back, Nima smiled and said: "We have become Wangfu Cliff here, your relationship is really good." ”

Xiao Xuanhan also replied with a smile: "Brother Renci is also very good to you, every time you go home, you ask long and short questions." He's the kindest man on the prairie. ”

Nima sighed softly and said, "We are all old husbands and wives, and besides, I am sick, and I have not left him a son and a half daughter, women can't have children, it's like a dry river in the desert, I'm sorry for him." ”

Xiao Xuanhan was silent.
