The invention of bearings is also a bit funny, because when the water lighter was created, the principle of roller bearings had been applied to the flywheel and rotating shaft of the water lighter. However, there were no bearings on the water lighter, but four independent rollers were added between the flywheel and the crankshaft. The entire mechanism was completely connected to the water lighter and was part of the water lighter mechanism.

This time, after hundreds of water lighters were manufactured in the manufacturing bureau, some craftsmen finally thought that if the connecting part of the crankshaft and flywheel on the water lighter was removed from the bulky and excess flywheel and crankshaft, and the rotating rollers and upper and lower parts were turned into an independent component, then this component could also be used in other places. So, the first roller bearing on the Silver Continent was born.

Until now, although these two things have been made, the craftsmen at the Manufacturing Bureau have not named these two things.

Yan Liqiang liked these two things very much, but what made Yan Liqiang even more happy and relieved was that he finally saw the vitality and creativity shown by the Manufacturing Bureau. With such ability, the Manufacturing Bureau is the Manufacturing Bureau in Yan Liqiang's heart.

At this moment, it can be named Screw, and the inventor's craftsman rewards 10,000 taels of silver!

This object can be named as a bearing. The invented craftsman rewards 20,000 taels of silver. This object can be used first on a water lighter on a four-wheeled carriage. You can consider connecting the flywheel and the crankshaft and use this object instead. There is room for improvement in both screws and bearings. I hope the craftsmen in the bureau will continue to study and continue to work hard!

Seeing that many craftsmen in the game are creative, they are used to using pencils to make drawings. The sizes and dimensions in the pictures are clearly marked, I feel very relieved!

Yan Liqiang took out his pen, finished writing the official documents reported by the Manufacturing Bureau and noticed them. Then he put the official documents together and placed them beside the table. After drinking two sips of tea and resting for a while, he asked someone to call the chief inspector of the Pingxi City Criminal Office waiting outside.

In just a moment, a man in soapy clothes came to the hall. As soon as he came in, he glanced at Yan Liqiang, who was sitting behind the case, and immediately gave a big gift to see him, "Han Ping, the chief inspector of the criminal arrest yamen in Pingxi City, pays homage to the supervisor!"

A strong beard with a big beard, a national face, a dark face, a strong body, and a uniform with a head-on uniform, such a person can just stand on the street, and he does have the momentum that makes the villains in the city frightened. This person is not unfamiliar with Yan Liqiang, but an "acquaintance". But who can know that such a person is actually a member of the White Lotus Sect...

Yan Liqiang sighed in his heart. The snake in his head had already started to move, but his face became even more kind, and he showed a smile, "Sit down, don't be stubborn. Speaking of which, it was the second time I met you. I remember the last time I met, a few years ago, Lord Sun came to Pingxi City to inspect and took down Ye Tiancheng. I went outside the city to search Ye Tiancheng's villa. I remember that at that time, you were leading the team outside the village..."

Hearing Yan Liqiang say this, Han Ping's face immediately showed a perfectly flattering and excited expression. As soon as his butt touched the chair, he immediately bounced up spring and bowed to Yan Liqiang again, "I was afraid of Hu Zhi. I didn't expect that the supervisor had met Hu Zhi a few years ago, but I still remember it!"

"Haha, I have a good memory. I remember that you were just a captain at that time. I didn't expect that you have become the chief captain in the past few years. You did a good job!"

"I am diligent in my duties, thanks to the promotion of Lord Wang Jianbei..."

"Do you know why you are asked to come this time?"

"You can guess a little bit!"

"Haha, you're so honest, then tell me why I asked you to come!"

"The Lord called Bei Zhi, probably because of the disappearance of the Gongdao Society student!"
