"Everyone works hard and gives me all the strength at home and in the mother-in-law. The Lord's house pays us wages and takes care of our bread. If you dare to be lazy, it's a donkey who gave birth to a bitch. The chief was hunched up, but his voice was like a bell.

"Don't worry, Captain, we don't have lazy people." The tenants answered.

The lieutenant elder was too old to do heavy work, so he was arranged by Li Chen to work as a supervisor. Originally, it was also to open two coppers a day, but the chief was unwilling to accept it, and finally the two bargained for one copper.

The first emperor has just unified the currency, and the purchasing power of this copper is full, and a copper can buy more than ten catties of flour.

"硜, 硜, 硜."

"Unit, unit, unit."

"Boom."

The men first cut a gap in the bucket-thick tree in one direction, then tied a rope to the tree and pulled it in one direction with all their strength. The trees fell with a bang, and someone immediately cut down the canopy branches, sawed the trunk into equal-length segments with a saw, and then split them into piles with an axe.

This is like the assembly line in the previous life, each with its own division of labor, which can ensure the most efficient way of working.

"硜, 硜, 硜."

The man in charge of cutting the tree was tired and sweating profusely, and Li Chen asked when he saw this scene.

"Why don't you cut down trees with a saw, the saw should save some effort."

"The master doesn't know that this Luban saw is good for cutting down some small trees. If it is used to cut down these giant trees, it will often get stuck. It's not as good as this axe. The young man who cut down the tree wiped the sweat on his head and said.

Li Chen picked up a saw and looked at it. The saw used in the Qin Dynasty, said to have been invented by Lu Ban, was cast in bronze with large serrations and neatly arranged.

"Big Niu, come here." Li Chenchong shouted to the big cow who was making an earthen kiln by the river.

"Go and make a saw, according to this sawtooth three times smaller, widen the whole, slightly narrower in the front, make the sawtooth tilted left and right, and add a handle at the back." Li Chen handed the bronze slip in his hand to Da Niu and said.

"Boss, can this saw work?" Da Niu looked at the drawings and said in his heart.

In about an hour, the big bull brought back the well-modified bronze saw.

"Sneer, snort, snort."

Saws swiped across tree trunks, and sawdust fluttered like snowflakes.

"So fast, so fast, so fast."

The tenants shouted from the side that the saw invented by the master was really different from the Luban saw, and the efficiency of working with this saw had been improved, and there was still a lot of strength left.

"If this saw can be popularized, women and children can chop wood and wood alone, and if the production method of this saw is passed on to the county government, they can also get a lot of rewards." The lieutenant said.

"Then I'll leave it to the chief." Li Chen said.

"Boss, just make the sawtooth smaller and denser. With this small change, the effect of the saw is ten or a hundred times stronger than before. "The big bull has become a hundred thousand whys at the moment.

"The purpose of the rack is to form a wider groove on the sawn object, so as to avoid the increase of frictional resistance, which will cause the sawtooth to heat and deform, or even break.

The dense little serrations of the triangle are very sharp, and when the sharp tips move on the surface of the object, the tooth tips will destroy the structure of the object, causing it to quickly turn into powder. Li Chen said to Da Niu Science.

"It sounds amazing, but I don't understand." Da Niu scratched his head and said.

"Get out." Li Chen scolded.

This bastard will always have a special way to make people's mood worse.

Three days later

"Dig, dig out all the black mud, we want the yellow mud below." Li Chen stood by the river, a group of shirtless men in the river, swarthy with black mud.

"The main house, unearthed." A man in the river shouted, clutching a piece of yellow river soil in his hand.

"Start digging around you and dig out all the yellow mud in this river." Li Chen said, and the piece of yellow clay that was thrown up was folded into a bowl shape and thrown to the ground.

"Smack." There was a crunch.

"Boss, let's cut off the river and dig up the mud in the river, so you are thinking about this." Da Niu happened to see this scene, and he looked like a sudden fog.

"Smack."

"Get out of the way." The yellow mud bowl was thrown in the face of the big bull, and Li Chen really didn't want to talk to this second cargo.

"Smack."

"Smack."

"Boss, don't say it's fun."

"and dig the mud." Li Chen shouted at the two goods.

By the river, under the willow trees, tender and slender strips of paper swayed in the breeze.

Li Chen and Lao Li sat on their knees under the willow tree and chatted.

"Captain, do you know Qin Brick?" Li Chen asked.

"The Qin bricks are about nine inches long and seven inches wide, and they are made of Lishan lead clay stirred with glutinous rice juice. Each brick is engraved with a small seal of the sea and the ministers, the age is mature, the Tao is not hungry, these twelve fonts. The lieutenant said.

"Qin bricks are not common, and in the entire Xianyang City, I am afraid that only Afang Palace is made of Qin bricks. The chief can know so clearly, he must also be a person with a story. Li Chen looked at the non-amazing Li Chang and said with some surprise.

"Thinking too much, I burned the kiln for Qin bricks." The lieutenant took a puff of dry cigarette and said lightly.

"Captain, do you know what I'm digging this yellow mud for." Li Chen asked

"Burn bricks, don't burn bricks, why do you ask me Qin bricks!" The lieutenant spat out a smoke ring, still very calm.

It seems that the chief has also learned badly from the big cow, and he can't talk well. was scolded one after another, and Li Chen thought that he wanted to revive the majesty of the main family.

"Starting tomorrow, you will take everyone to burn bricks." In the evening, Li Chen said to the big cow who had just finished washing his black mud.

"Boss, let's use a stone to build a house. Tomorrow I will take someone to the back mountain to chisel, burning bricks with glutinous rice juice is too luxurious. Da Niu said.

"Who told you that you must use glutinous rice juice to burn bricks, listen well, I will leave the method to you. Tomorrow you won't be able to burn bricks, and your head will be punched in the stomach. Li Chen glared at this and nagged, and Da Niu shrank his head.

"The soil we take today is called clay, also called cement. Tomorrow you take someone to dry it, then crush it, and pass it through a sieve, leaving only the finest pure earth.

Moisten the pure soil with water, repeat it like noodles, step on it to make thick mud, and turn the mud and refine it at least 5 to 6 times.

The smelted soil is molded through billet molding, and the clay should be compacted when shaping, and the place where the bricks are placed should be covered with fine sand to prevent the soil from sticking. The bricks should be dried in the shade and must not be exposed to the sun, otherwise the bricks will be cracked and deformed.

After the bricks are completely dry, about three days or so, they can be fired in the kiln, using coal as fuel at first, and slowly burning with grass, pine branches and other fuels on the third day.

After seven days of firing, the green body is sintered. If the fire is slowly turned off at this time, the outside air enters the kiln, and what comes out is the red bricks. ”

"Boss, red bricks can't be burned, there are taboos." Da Niu listened carefully and hurriedly said.

"You bastard, there are still times when you are thick and fine." Li Chen scolded with a smile.

Daqin belongs to water virtue, likes black and hates red. If you build a house with this red brick, I am afraid that it will not be far from the extermination of the family.

"When you change the fire on the third day, seal the vent at the mouth of the kiln with mud to reduce the inflow of air, so that the bricks will be blue." Li Chen said.

"Boss, you know a lot, are they all written in this book?" Da Niu pointed to the bookshelf full of books.

Although Li Chen said that he was a shopkeeper, he was not idle all day, and he had already engraved the collected books on the bamboo slips. After all, in Daqin, a society with bamboo slips and juan as the main text carriers, the books on the earth are too shocking.

"Yes, the books in my house are priceless." Li Chen said.

"Can I take a look?" Da Niu scratched his head embarrassedly.

"Just look at it, it's a good thing to love reading." Li Chen said.

After a pillar of incense

"Purr, purr."

"Smack."

"Get out of here, and when I see you touching my book, my hand will break you later."

Li Chen looked at the saliva on the ground, the fifth-grade physics bamboo slip. I can't wait to slap myself twice, how did I think of letting this bastard study.
