"Lao Zhao, bring over the saw we made!" Zhang You raised his voice and shouted to Zhao Shizhen, who was staring at a blacksmith busy.

Zhao Shizhen looked back, only then did he see Zhang You and them, and walked a few steps over: "What did you just say, my lord?" When did you come, the lower officials didn't hear it! ”

"You're too focused, I mean, let you bring that saw we made, and we're waiting for someone to arrive."

"Really?" Zhao Shizhen glanced at Li Quanfu in the wheelchair suspiciously, but didn't ask much, but continued: "Yesterday, the power unit was also made, it has been assembled, and it is inconvenient to move, so let's go over with the lower officials to take a look." ”

"It's fast!" Zhang You was overjoyed when he heard this, and pushed Li Quanfu to follow Zhao Shizhen out of the door - the head manager has inconvenient legs and feet, and occasionally uses a wheelchair, so a special ramp is set up at the door of each room in the Gewu Institute, which is convenient for Li Quanfu today.

The carpentry operation room is more spacious than the blacksmith operation room, and several carpenters from other yamen are busy inside, Zhao Shizhen did not enter the door after entering the small courtyard, but walked directly to the south wall, where there is a grinding device, two donkeys with red cloth and grass hanging in front of their noses are constantly rotating around the center.

"...... this?" Li Quanfu was anxious to see clearly, and couldn't wait for the wheelchair to be pushed closer, so he got out of the wheelchair directly and limped over. Seeing this, Zhang You hurriedly followed.

When you get closer, you can see clearly, the range of the two donkeys walking, under the feet is a circular wooden platform with a diameter of more than five meters made of wooden planks, next to the wooden platform, there is a strange iron shelf, and on the platform above, a circular steel disc is surrounded by serrations, which is rotating rapidly.

A carpenter came from the operation room, and after greeting everyone, he picked up a wooden board and put it on the platform, pushed it hard, and saw that the five-centimeter-thick wooden board was quickly divided into two halves by the rapidly rotating disc.

Li Quanfu and Li Yan were dumbfounded, looked back at Zhang You, and asked at the same time, "You also made it?" ”

"Old man, our Lord Zhang is a genius of Gewu, so don't be surprised if you do anything...... Let's just talk about this lazy saw, who would have thought that the saw blade could be made into a circle? Zhao Shizhen waved his hand to signal the carpenter of Shicai, and saw that he pulled something, and the originally flying disc gradually stopped.

Li Quanfu stepped forward and squatted to observe, only then did he discover the mystery.

It turned out that the power was indeed generated by the two donkeys, as he had guessed, and a wooden groove more than three feet wide extended from the bottom of the wooden platform, and in the groove near the saw was fixed an iron serrated disc, under which were two ropes twisted like cow tendons, and under their action, the discs were still rotating rapidly, biting a series of large and small iron discs with serrated teeth, and they were also rotating rapidly with its rotation.

The lever wrenched by the carpenter controlled a small serrated iron disc that connected the upper and lower discs of the same shape, and when separated, the lower one still rotated, while the upper one stopped.

"It's so delicate, this is the legendary gear, right?" He muttered that he had only heard of such a complex transmission, but it was the first time he had seen a real thing.

"This is not my credit, it is Lao Zhao and Mr. Guo and their staff Tang Dynasty monks, and the description of the water transportation armillary sphere made by Liang Lingzan is copied, not everyone's brainstorming, this lazy man can't turn the saw." Zhang You said with a smile. Zhao Shizhen said: "My lord is humble again, if it weren't for your guidance, we wouldn't be able to think of the water transport armillary sphere." ”

Guo Zaoqing, who had not spoken, interjected with a smile: "Okay, okay, you two don't be modest, in a word, the significance of this transmission device must be unprecedented, not only can it be used on this lazy saw, looms, fans, and many equipment that was previously limited by power devices." This is thanks to Zicheng's standardized weights and measures, if it weren't for his vigorous promotion in our Gewu, even if we could make gears, we would definitely not be able to do it so exquisitely. I was about to write this as a concert for the imperial court......"

"Forget it, sir," Zhang You suddenly interrupted Guo Zaoqing and said: "The generation of any new thing will be accompanied by countless voices of doubt, so the Shangshu Imperial Court is just adding trouble, you believe me, as long as our Gewu Institute has maintained the current situation of high research and development results, the standards we use will subtly affect those departments that cooperate with us, such as the War Bureau, such as the Imperial Works...... 'sneaking into the night with the wind, moisturizing things silently', any reform, in fact, this state is the best state." ”

Guo Zaoqing was stunned for a moment, smiled, and said: "You, Gao is always at odds with the world, pondering carefully, but it is quite reasonable. Okay, I'll listen to you, and this matter won't go to the court. ”

"Why don't you say that adults' brains don't look like ours." Zhao Shizhen echoed with a smile, praising on the surface, but there were some jokes. After a long time of contact, he has long figured out Zhang You's temper, and he hates talking with a shelf the most, so in addition to the necessary respect, it is a very common thing to make a joke or something.

"That is, don't look at who I am, I know five hundred years before, five hundred years later, heaven and earth, omniscient, known as smart and chic, jade-faced handsome guy......"

"Gotta have it, say you're fat and you're still panting...... Let's hurry up and tell your grandfather about your blower idea, it's been less than twenty days since the agreement with Qi Shuai. Guo Zaoqing reluctantly interrupted Zhang You, why did you recognize such an apprentice in the first place? This thick-skinned person can't even penetrate the musket, right?

After lunch, Li Quanfu and the carpenters began to work intensively, Zhang You read for a while, remembered the matter of the newspaper, told everyone a few words, and led Li Yan and Lao Qian out of the door.

Send Li Shuo and Li back to the house first - the day of moving has come, Li Shuo has moved out of Li Wenjin's mansion, Mrs. Zhang bought a few waiting maids, and now the mansion of the head of the Gewu Institute has the appearance of home, everything is ready, just wait for Zhang Rang Dasheng to return and marry Zhang Jialin into the door.

Tang Erzhuang's training has begun to bear fruit, the line is like the wind, the order is prohibited, and the murderous spirit is soaring, when he first came, the appearance of the soldier who was hanging Erlang has long disappeared, and there is no need to make a move, just that momentum is enough to make the legs and stomachs of the timid people turn around.

Because the courtyard that Zhang Youxin bought for printing newspapers was in the lighting workshop, which was a bit far away, Li Yan specially called a team of guards, led by Bi Hongquan, more than ten people each rode a horse under their crotch, and left Zhang's mansion in a mighty way, while Cao Aijin stayed in Zhang's mansion and continued to train the other team of guards led by Tang Erzhuang. When he was about to arrive at the entrance of the light market, he saw a large group of people in front of him from a distance, Bi Hongquan was sharp-eyed, and hurriedly said: "That's not Lord Gu, there are a few yellow hairs." ”

Qian Wugua also followed beside him, and when he heard this, he looked at it carefully, and said: "Look at their dress, a bit like a priest, well, it's similar to the monks and Taoists on our side, but the person they believe in is not the Buddha or the Jade Emperor, it's called God...... Aren't they all hanging around in the south, why did they come to Jingshi? ”
