After transporting the wood back to Dongzhong County, they began to prepare for charcoal burning. Pen ~ fun ~ pavilion www.biquge.info

The five brothers knew very well that a charcoal kiln was needed to make charcoal, but in the cave, the charcoal kiln could not be made very large.

A charcoal kiln two meters long, one meter high, one meter wide, was built on the rock wall at the end of the cave by the five brothers of the Zhu family and their five apprentices.

There is a chimney on the charcoal kiln and a fire tunnel underneath, which is used to burn the fire. Moreover, the door of the charcoal kiln is very small, which is to seal the door in time and let the wood slowly carbonize inside.

Burn charcoal, not on a large fire, as this will only turn the wood to ashes. The wood must be burned little by little, slowly carbonized.

Preparing everything, it was already two o'clock in the morning, and in order to catch up with the explosion in the morning, they did not rest, but immediately put the wood into the charcoal kiln to prepare for firing.

"Eighth brother, let the soldiers bring the timber over," Zhu Ziju shouted as he stood at the entrance of the charcoal kiln cave and walked towards the middle of the cave.

In the middle of the small cave, there are six hundred pieces of wood, which are piled up in several piles and formed into a mountain.

Ye Cheng stood next to one of them, sweat on his face.

There was a lot of heat around him, and all of them were emitted by the three furnaces on the left side of the cave.

The furnace was burning with fiery iron slurry, and the cave was fiery red because there were three furnaces.

The slurry is made from iron ore firing, which is poured into a mold to make a semi-circular piece of iron.

Two semi-circular pieces of iron are spliced together to form a vessel for exploding.

The abrasives are made of clay, so the surface of the container is very rough.

These rough containers had been stacked on the right side of the cave, and after a few days of rushing, the containers were piled up as high as a mountain.

Hearing the shouts of Zhuziju, Ye Cheng knew that the charcoal kiln was ready, he quickly turned to face the soldiers, and said, "Quick, transport the wood to the charcoal kiln."

"Yes"

Two hundred white-robed soldiers were already standing next to the pile of timber and getting ready, and when the order was given, each of them carried two pieces of wood on their shoulders and ran towards the charcoal kiln.

Although it was already two o'clock in the morning, everyone was still in good spirits, and everyone was full of energy, whether it was the people who were transporting wood or making containers.

Ye Cheng knew that he couldn't relax, so he picked up one and ran towards the charcoal kiln.

In front of the charcoal kiln, Ye Cheng handed over the wood to Zhu Ziju, looking at the small charcoal kiln, he asked suspiciously, "Brother Ziju, how much wood can this charcoal kiln fire?" ”

Zhuziju took the wood and slowly stretched it into the narrow hole, explaining, "I think it should be no problem to fire dozens of them at the same time."

"Dozens?" Ye Cheng lowered his head and pondered.

A few dozen pieces of wood can make a lot of charcoal, and it needs to be mixed with sulfur and saltpeter, so it should be no problem to make a blast that can handle a battle.

After dozens of pieces of wood were finished and put into the charcoal kiln, Zhuziju began to draw fire under the fire channel, and the flames burned to the wood through the cracks above the fire channel.

When the wood reaches the ignition point, it burns little by little, slowly burning down to the entire strip of wood.

Soon the charcoal kiln was filled with fire, and the chimney began to smoke. Now it only takes a few dozen pieces of wood to completely burn through to seal the hole and chimney.

If there is no air in the charcoal kiln, the fire will be extinguished naturally, and then the carbon will be completed, just wait for it to cool down the next day.

After burning for a while, through the narrow hole, he saw that the fire in the charcoal kiln was already very strong, and Ye Cheng knew that it was okay.

But when it comes to firing things, Zhuziju knows better.

So Ye Cheng just watched quietly from the sidelines.

Zhu Ziju looked down at the situation in the charcoal kiln, and then quickly shouted, "Ziping, seal the chimney"

When Zhu Ziping heard the shouting, he immediately covered the chimney with a cover plate, and then pasted the mud on it to prevent a little air from entering the charcoal kiln.

Zhuziju also used the same method to seal the entrance of the cave and the entrance of the fire path.

Ye Cheng was helping to paste the mud on the side, and he could feel that the wall of the charcoal kiln was very hot on the palm of his hand, and as soon as the mud was pasted, it dried out and cracked, and he had to paste more mud on it.

The cave with three furnaces and a charcoal kiln is as hot as a hot summer

Next to the charcoal kiln, Ye Cheng was sweating profusely, rubbing it lightly with his mud-stained hand, and took a deep breath, now he can be regarded as resting.

Now the whole charcoal kiln is in a closed state, and there is no need to manage it. The kiln is surrounded by mud, so air cannot enter, and when there is no air inside, the fire will automatically extinguish.

"Okay, now when the charcoal kiln cools, you can take out the charcoal," Zhu Ziju said, pushing his hands against each other, trying to get rid of the mud stuck to his palms.

"Hmm" Ye Cheng smiled slightly, seeing Zhu Ziju's actions, he suggested, "Brother Ziju, let's go find water to wash, and then go and see what the other people are doing now"

"Hmm," said the princes.

The two came to a wooden barrel full of water, the water in the barrel was already muddy, but the two did not care, and put their dirty hands into the barrel.

Ye Cheng rubbed his hands together and said, "Brother Ziju, how many days have you been busy like this?" Isn't it time for them to take a break" He only came to Dongzhong County today, I don't know how long everyone hasn't rested, and he is a little concerned.

"You haven't rested for three days, and now that you're back with the other soldiers, it's time for them to rest," Zhu Ziju explained.

"Well, then I'll let those two hundred soldiers exchange with them later," Ye Cheng said.

After two hours of busy work, it is now four o'clock in the morning, and there are still two or three hours before dawn, and everyone can take a break in shifts, which is very helpful for work.

"I don't know what the situation is at the front now? Just in case, let's go out and remind those patrolling soldiers later, and arrange shifts by the way, you can't let all the soldiers patrol together" Ye Cheng said secretly in his heart.

It's four o'clock in the morning, and it's easy for people to get sleepy, and it's also when people are asleep, so it's easy to be attacked.

Fortunately, Lai Zhongjin left 1,500 white-robed soldiers, which has a certain guarantee for the safety of Dongzhong County.

Outside the cave, there is a mountain road around the mountain.

A large number of bonfires are still lit on the mountain roads, these bonfires are to make it easy for the patrol soldiers to detect the enemy's sneak attack, and if there are no bonfires on the mountain roads around the mountains, it may attract the attention of the enemy, because the county seat of the Tiangu Kingdom is like a fire snake entwined when it gets dark.

On the outside of the mountain road around the mountain, a white-robed soldier stood a few meters away, facing the outside of the mountain. They must be fully engaged in discovering the movements that are hidden in the darkness.

If there is any movement, the soldiers patrolling the mountain road must be alerted in time.

The patrol soldiers consisted of ten people, who walked slowly from the top of the mountain to the bottom of the mountain. But ten people alone can't safely patrol the whole mountain, so these ten-person patrol teams have 20 groups, and no groups are 30 meters apart, so that if there is an accident, the two groups can rush to help in time.
