Now, it is the time for the slack farming, which should be the most leisurely time for the farmers. But Lijiazhuang seems a little deserted at this time, and the factories in the village have already begun to resume production. The farmers in the village will also go to the factories to do odd jobs during the slack farming. Although the farmers have no skills and can only do some vulgar groceries, they can at least make an extra income during the slack farming farming. This naturally makes the farmers look a little deserted.

People in Lijiazhuang can be model workers of this era. Even if the New Year is a big deal, there are only these three holidays. When the factory in Lijiazhuang is in three hours, the Qin Dynasty is an agricultural society, not an industrial society. Under this premise, if you want to increase the output of "Xianyang" production, you can only rely on workers to work overtime.

Soldiers who don’t want to be generals are not good soldiers. Similarly, employees who don’t want to be bosses are not good employees. When the factories in Lijiazhuang are working overtime, do you think Li Chen is happy? No, you can’t imagine Li Chen’s happiness.

After breakfast, Li Chen walked slowly to the factory. Today's breakfast was buns and Hu La Tang. Under Li Chen's guidance, the development speed of Lijiazhuang's food culture is no less than the development speed in technology. This is a perfect trend of light industry relying on catering, and heavy industry relying on technology.

"Mr. Marquis, it's early."

"Mr. Marquis, I didn't sleep for a while."

Li Chen just walked into the arsenal yard slowly and the farmers who were hurriedly carrying raw materials into the factory greeted Li Chen one after another.

In the northwest corner of the yard, it is far away from the factory and it will not hinder the migrant workers coming and going. Daniu is leading a group of folk scientists from Daqin, fiddling with something.

Hearing that Li Chen was coming, everyone put down their work and made a way to let Li Chen go to the crowd.

"Mr. Marquis, why are you so busy? Why are you free to come to the factory again?" Daniu wiped his sweat with his dirty hands and asked in surprise.

"Busy? Am I not busy?" Li Chen didn't react for a moment and asked in surprise. But in the blink of an eye, he saw a silly smile on Daniu's innocent face. Li Chen knew that this guy must have nothing to hold back.

"Mr. Marquis, aren't you busy making dolls?" Big Niu licked his face and smiled.

"Bang?"

"You're just talking nonsense." Li Chen slapped the big bull in the head and said angrily.

Daniu looks honest, but in fact he is very dishonest, and he talks in a slutty way.

"What are you fiddling with?"

The rough man of Big Bull has thick skin and flesh, and Li Chen's slap on his body would make him tickled.

"Manually drilling the barrel is too much trouble, and the output has not increased. I got a tool, which has increased the speed by more than ten times.

He took Daniu away and Li Chen saw what Daniu was tampering. In front of him was a plane that was large in the door panel, which was made of fine steel. The plane made of steel was fixed on four huge cement piers, which ensured that it would not move when under stress. On the steel plate, there were five grooves, which could just place the thick embryo of the barrel inside.

The other side of the steel plate corresponds to the grooves are five stainless steel drill bits, which are made of smelted steel. The drill bit is connected to the drill bit is a gear that is a millstone, and the gears and drill bits are connected together by several belts, just like the belts that connect tractors in the past life.

"Is this thing a drilling machine?" Li Chen said in surprise. He never expected that the big bull could make this thing.

"What? The drilling machine, since it is named by the Marquis, it is called the drilling machine." Daniu scratched his head and said silly.

"Can this thing move?" Li Chen asked with a deep breath. Although this drilling machine is a bit simple, Daniu really shocked Li Chen. The drilling machine is a ladder from an agricultural society to an industrial society. With the drilling machine, it has given wings to Daqin's technology.

"You can move, but why can't you move? The donkey is going up and drilling a hundred gun barrels only requires a bag of coarse grains." The big bull said excitedly, and there was still some pride in his excited tone.

Nowadays, the manufacturing progress of gun barrels is very slow, and manual drilling is very slow, and it is necessary to operate by craftsmen with very advanced skills. Even if a craftsman works overtime every month, he can only drill fifty barrels. There will be 20% of the defective products in these fifty barrels, which is also a problem with the manufacturing process of the barrel, which makes the output unable to be increased for a long time.

As if he was afraid that Li Chen would not believe it, the big cow instructed his craftsman to lead a donkey and tie it to the gear, and then took out five thick barrels and stuck it on the groove of the drilling machine.

The thick barrel billet is a cast copper stick. There is no seamless steel pipe in this era. The materials of the barrel are cooked copper, and the hardness of copper is far less than that of fine steel, which is convenient for drilling.

“Oh, oh, oh.”

A craftsman set up a donkey and slapped it on the butt. The donkey pulled the mill easily. In the eyes of the donkey, he seemed to be no different from pulling the mill, but he pulled the donkey and found that it was a bit difficult to pull the mill. This is the donkey king of the old village chief of Lijiazhuang. This donkey is very strong. Even if he pulls the heaviest mill in Lijiazhuang, he can only use half of his strength. But now the donkey has used all his strength, but he still walks very slowly. Although he is very tired and walks very slowly, what is the mill? This is the donkey, what is the quality of the donkey? That is stubborn.

The king of the donkey is naturally the king of stubbornness. The more it can't pull, the harder it pulls. The stubbornness seems to be competing with the gears. Although it moves slowly, it walks very steadily, turning the gears bit by bit.

The donkey pulls the gear, and the gear drives the belt, and the belt drives the drill bit, and the drill bit drills into the thick barrel. The donkey has much strength than the human being, and the lathe is much more stable than the lathe. The thick barrel is drilled at a speed visible to the naked eye, which is more than five times the power of manpower. You must know that this is drilling five barrels at the same time. Five five is twenty-five, and the output of guns has increased by thirty times when rounded.

"Buzz,buzz,buzz."

Due to friction, the drill bit and the barrel thick blank begin to splash out sparks. The big bull lifts the kettle and pours it on the drill bit to cool down the drill bit.

After about half an hour, the drill bits had already penetrated into the thick blank of the barrel, and the thick blank also became the barrel.

"Bang." The craftsman in charge of driving the donkey slapped the donkey on the butt.

Obviously, this donkey was an experienced donkey. When the craftsman slapped it, the donkey changed direction and began to pull the mill. As soon as the donkey changed direction, the drill bit was withdrawn from the thick barrel bit by bit.
