At this time, it stands to reason that it is the time when the farmers are slack, and it should be the most idle time for the farmers. But Lijiazhuang was a little deserted at this time, and the factory in Zhuangzi had already begun to resume production. The farmers in the Zhuangzi will also go to the factory to do some odd jobs during the slack time, although the farmers have no skills and can only do some vulgar groceries, but they can also earn an extra income during the slack time, so the Zhuangzi naturally seems a little deserted.

The people of Lijiazhuang can be said to be model workers in this era, even if it is a big event of the New Year, there are only these three days of vacation, and the factory in Lijiazhuang will start work as soon as it arrives in three days. Daqin was an agrarian society, not an industrial one. Under this premise, if you want to increase the output of "Xianyang Manufacturing", you can only rely on workers working overtime.

A soldier who doesn't want to be a general is not a good soldier, and in the same way, an employee who doesn't want to be a boss is not a good employee. 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 steamed buns and spicy soup. Under the guidance of Li Chen, the development speed of Lijiazhuang's food culture is not inferior to the development speed of science and technology. This is a proper light industry that relies on catering, and heavy industry relies on the strength of science and technology.

"Master Hou, it's early."

"Master Hou, the newlywed Yan'er didn't sleep for a while."

Li Chen had just walked into the courtyard of the arsenal slowly, and the farmers who were hurriedly transporting raw materials to the factory greeted Li Chen one after another.

The northwest corner of the courtyard is far away from the factory and does not interfere with migrant workers. Da Niu is leading a group of folk scientists from Daqin, tinkering with something.

Hearing that Li Chen was coming, everyone put down what they were doing, made way for a road, and let Li Chen walk to the middle of the crowd.

"Master Hou, you are so busy, why are you free to come to the factory?" Da Niu wiped his sweat with his dirty hands and asked in surprise.

"Busy? Am I not busy? Li Chen didn't react for a while, and asked in surprise. However, in the blink of an eye, he saw a smile leaking out of Da Niu's honest face, and Li Chen knew that this kid must not be holding back any good fart.

"Master Hou, aren't you busy making dolls?" The big cow licked his face and said with a smile.

"Smack?"

"It's just your kid's nonsense." Li Chen slapped Da Niu's head and said angrily.

Da Niu, this kid looks honest, but he is actually very dishonest, and he talks a lot.

"What are you messing with?"

Da Niu, a rough man, has rough skin and thick flesh, and Li Chen's slap on his body is like tickling.

"It was too much work to drill the barrel by hand, and the output couldn't go up, so I got a tool and the speed was more than ten times faster.

Saying that, Da Niu got out of the way, and Li Chen saw what Da Niu was messing with. In front of him was a flat surface the size of a door panel, made of stainless steel. The steel plane is fixed to four large cement piers, which ensure that the force does not move. On the steel plate, there are five grooves, which are just right to place the rough blank of the barrel inside.

On the other side of the steel plate, corresponding to the groove, are five stainless steel drill bits, which are made of stainless steel. Attached to the drill is a gear the size of a grinding disc, and the gear and drill bit are connected together by several belts, like the kind of belt that connected tractors in previous lives.

"This thing, it's a drilling machine?" Li Chen said in surprise. He never expected that Da Niu would be able to get this thing out.

"What? Drilling machine, since it is the name given by Hou Ye, it is called a drilling machine. Da Niu scratched his head and said innocently.

"Can this thing move?" Li Chen took a heavy breath and asked, although this drilling machine is a little simple, but the big bull really shocked Li Chen. The drilling machine is simply the ladder from the agricultural society to the industrial society, and after having the drilling machine, it is simply giving Daqin's science and technology wings.

"I can move, why can't I move. The bolt-headed donkey goes up and drills a hundred barrels and only needs to consume one bag of coarse grain. Da Niu said excitedly, and there was some little pride hidden in this excited tone.

Nowadays, the manufacture of gun barrels is very slow, and the use of manual drills to drill the barrel is very slow, and it requires very skilled craftsmen to operate. Even if a craftsman works overtime to drill gun barrels every month, he can only drill 50 barrels. There will be 20 percent defective products in these 50 barrels, and it is precisely the problem of the manufacturing process of the barrels that makes the production delayed.

As if he was afraid that Li Chen would not believe it, Da Niu instructed his craftsmen to lead a donkey and bolt it to the gear, and then took out five barrel blanks and stuck them in the grooves of the drilling machine.

The barrel blank is a cast copper rod, and there is no seamless steel pipe in this era. The barrel is made of wrought copper, which is much less hard than steel, so it is convenient to drill holes.

"Boom, boom, boom."

A craftsman put on the donkey, then slapped it on the donkey's buttocks, and the donkey pulled up and grinded it with ease. In the donkey's opinion, there is no difference between himself and the usual grinding, but pulling the donkey and finding that today's grinding is a bit difficult to pull. This is the donkey king of the old village chief of Lijiazhuang, and this donkey is very strong. Usually, even the heaviest grinding in Lijiazhuang only exerts half of its strength, but today the donkey has used all its strength, but it still walks very slowly. Although I am very tired and walk very slowly, what is this, what is this, what is the quality of a donkey, that is stubbornness.

This king of donkeys is naturally also the king of stubbornness. The more it can't pull, the harder it pulls. The stubborn donkey seemed to be competing with the gears, and although it was moving slower and slower, it was walking steadily, turning the gears little by little.

The donkey pulls the gear, the gear drives the belt, the belt drives the drill bit, and the drill bit drills into the barrel blank. The donkey is much stronger than a man, and the lathe is much more stable than a man's hand. The barrel blank was being drilled at a speed visible to the naked eye, which was more than five times that of human labor, and it was necessary to know that it was drilling five barrels at the same time. Five-five is twenty-five, and the production of guns is increased by a factor of thirty when rounded.

"Buzz, buzz, buzz."

The drill bit and the barrel rough began to spark due to friction. The bull lifts the kettle and pours it on the position of the drill bit to cool the drill bit.

About half an hour later, the drill bit had sunk into the barrel blank, and the rough blank had become the barrel.

"Smack." The craftsman in charge of driving the donkey slapped the donkey on the buttocks.

Apparently the donkey was an experienced donkey, and when the craftsman slapped it, the donkey changed direction and began to grind. As soon as the donkey changed direction, the drill bit was withdrawn from the barrel blank little by little.
