The strength of bamboo is good, but the rim made of bamboo, this makes Li Yuanxing not very relieved, and it doesn't look rough. But Li Su is full of confidence.

"The rattan is too brittle, but it's not good!" Li Su explained to Li Yuanxing.

Li Yuanxing didn't try the car, just pushed it up and looked at it.

The car has fenders, as well as shelves in the back. The rear wheels are obviously twice as thick as the front wheels, probably considering that the rear can be loaded with heavy objects, and the front wheels are a little thinner. Seeing the front wheel, Li Yuanxing was surprised to find that there was no fork yet!

"This, what do you think?" Li Yuanxing asked.

"It's very difficult to make it straight, but it's much easier to make it like this." A craftsman replied in place of Li Su.

Li Yuanxing nodded, the front fork of the bicycle also plays this role, which is not much help for balance, but it can make the front of the bike straight forward.

The other three, Li Yuanxing looked at it again and was even more interested.

All the cars are made according to the original principle of bicycles.

One is a bucket car, pedal-type, not paying attention to speed, only paying attention to strength. This is the human-powered version of the Han Dynasty car, the original automatic seeding machine of Datang.

Then one is a plow cart, three plows, four pedals, and two at the same time.

The zuihou one, which is a wide wheel small board car, belt driven, is obviously for the field, because the wheels are wide, so it can adapt to loose dirt floors.

Compared with bicycles, Li Yuanxing is more satisfied with these three tool cars.

Datang has no power machinery, and there is far from enough healthy cattle. But with these things, Datang's yield per mu will definitely rise.

"Very good, this king has decided to give you a big reward. At the beginning of next month, the king will naturally honor this reward, and now you can go and change your clothes and rest. ”

After Li Yuanxing finished speaking, Li Su shook his head: "Only when that is finished can you rest!" ”

"That!" Li Yuanxing looked in the direction of Li Su's finger, there were many metal workpieces there, Li Yuanxing took a closer look, and it turned out to be many bearings.

"Good. Very good. Go rest today, and tomorrow this king will send you a few good books, so that you can complete these bearings even more! ”

How much knowledge Li Su has, Li Yuanxing knows very well.

It's just that. He has this attitude. There is also this spirit of learning. Under his leadership, the craftsmen will work very hard.

Li Yuanxing returned to the study and wrote a watch seal himself. Then he wrote an official letter to the Ministry of Industry, and then came down to the Tenchi Division. The Ministry of Industry and Tianzhi Division are required to evaluate the labor achievements of Li Su's entire team, give certain rewards, and add points to the craftsman level.

Then he gave the workshop a handwritten letter and ordered it to consider the possibility of mass-producing the bike.

The next day, Li Yuanxing still did not go to Tianchi, and heard that the purple clay pot was rated as the champion pot of the first day. And the big red robe is the champion tea on the first day.

Li Yuanxing's mind is not on the tea, but on the bridge.

"It's just that the bridge deck is closed, and His Royal Highness will go in person, so I can't help but think too highly of this Li Chun." Lu Maofeng said on the side.

Li Yuanxing sat in the carriage, and nodded slightly when he heard Lu Maofeng's words: "Your words are good, they will be criticized." And this Li Chun may also be complacent, which is a big disadvantage. But the bridge, this king does not look at the heart of the uneasy! ”

"Why don't you go to Yaozhou?" Lu Maofeng suggested again.

"Just passing by? This proposal is good, but Yaozhou ......" Li Yuanxing hesitated, because tomorrow night is the time for him to return to modern times, if he goes to Yaozhou today, then he will have to rush back tomorrow, and now the new road cannot be used, and the time on the road is too long.

It's almost all spent on the road.

"Your Highness, I will send someone to make an arrangement in the Tiance General's Mansion, calculate the time, and say that there is an urgent matter that requires you to turn back to Chang'an, in short, you can't let that Li Chun think that you are specifically going to see him build a bridge, at most these days, the small one will send capable people to keep an eye on it day and night, Zuihou These days, the bridge must be connected."

Lu Maofeng doesn't understand the bridge, but he knows how to build it at one time, and His Royal Highness King Qin will definitely be happy.

"Forget it, I'm not going!" Li Yuanxing watched the carriage arrive at the Chamber of Commerce Street, thought for a while and said, "Turn around and go to Tianchi." The king of the Tianchi Festival always has to show his face, you arrange a few people to take a look, and the bridge must be repaired. ”

"Yes!" Lu Maofeng retreated, arranging a U-turn, and arranging for people to go to the Jinghe Bridge.

At the Tianchi meeting, Li Er sat on a high platform and watched the competition under the stage. The world's first martial arts club is compared to real kung fu. Whether these people will be used by the royal family, Li Er is still observing, whether there is any meaning in subduing. If you need to take it, then how should you take it better.

Li Yuanxing has some rangers in his hands, and they have been changed a lot.

Li Er knew that Li Yuanxing's swordsman named Yidao had made great contributions on the battlefield in Liaodong, and the ranger who was originally going to fight to the death with him also changed his mind, and the two made an agreement that each person would receive a task in the ranger hall, and if Wu Bin completed it first, then the previous hatred would be over.

On the contrary, if Wu Bin finishes it, then Wu Bin will go to the grave of the other party's younger brother and sacrifice for seven days and seven nights.

This is to let go of hatred for the country!

Li Er held his chin, thinking while watching the competition, those who could compete on this martial arts platform were all masters left after several rounds of competition.

"Uncle Bao, what do you think?"

"Holy Lord, these two people are not good, but they are proficient in the art of fighting alone, and they can't become generals among the ten thousand armies!" Qin Qiong is a master among the masters, even if he is in his heyday now, he will not participate in such a competition, this is a matter of identity, and what Qin Qiong has learned, and after these years of fighting, it is more about the ability on the battlefield.

Li Er was very satisfied with Qin Qiong's comments and nodded slightly.

Gonggong Gao came over at this time to report: "Holy Lord, His Royal Highness King Qin has arrived at the foot of the mountain, and he will be here soon!" ”

"Gorou is thinking about coming!" Li Erle was happy.

"If you go back to the Holy Lord, His Royal Highness King Qin seems to have turned around halfway, for some reason, he turned around from Chamber of Commerce Street. The sergeant patrolling at the foot of the mountain said that the procession of His Royal Highness King Qin was an official guard of honor. ”

Li Erxin said that Li Yuanxing may want to go there, and the most likely thing is to see the bridge at the Jinghe River.

However, Li Yuanxing was right not to see the bridge, and there was no need to care too much about a bridge with the respect of King Qin.

Li Yuanxing was at the bottom of the mountain and was about to go up the mountain, but he saw a guard rushing over, and after seeing Li Yuanxing, he handed over a document to Li Yuanxing with both hands.

This is the document of the Tenchi Division.

Li Yuanxing opened it and looked at it quickly, and Tianzhi Division determined that the wheel rim of the bicycle, the weaving method of bamboo and linen, and the glue were a very clever way and could be classified as a seventh-class invention.

The ratchet of the belt conveyor wheel is very clever, just a small piece of bamboo, and it solves the problem of reversal.

This is a fourth-class invention.

Manpower carts, plow carts, and board carts are just assembled with the help of too many predecessors, which are not creative inventions, and can only be classified as pioneering inventions, so they are rated as sixth-class inventions.

Next, the second-class invention of the four words surprised Li Yuanxing.

Oil-injected soft tin-copper bearings, replaceable bearing sleeves.

This item gave a second-class reward for creating inventions, Li Yuanxing did not say it, the prototype of this jishu was given to the workshop by himself, but they did not build it according to the prototype, but made a set in their own way according to the craftsmanship of Datang.

The original purpose of this thing was to make a bearing for bicycles.

Tenchiji's opinion is that this invention has a wide range of uses, whether it is a waterwheel, a loom, a windmill, etc., it is already too useful.

Li Su, specially rated as a fourth-class craftsman, the rest of the participating craftsmen are promoted by one level, and the third-class craftsman is the upper limit, which was originally a third-class craftsman, which can be counted as a bonus point, in a word, the second-class craftsman is absolutely impossible to give.

Li Yuanxing held this document, and there was a little more excitement in his eyes.

Tianchi Taiyi Temple, Li Er left Guanwutai and waited for Li Yuanxing in the lounge, he wanted to talk to Li Yuanxing about the Jinghe Bridge, Li Chun could give a first-class craftsman, but it was just a bridge, Li Yuanxing didn't need to care too much. It's not that the bridge is not important, but that the status of King Qin is too high.

It's like if the Tang Emperor cares about who builds a house, it's an unreliable thing.

"Brother Huang!" Li Yuanxing bowed and sat down.

"I heard that Gorou was transferred to Tianchi halfway, and I thought that Gorou came out for the matter of the bridge. Gorou, it's just a bridge. After Li Er finished speaking, he looked at Li Yuanxing's eyes, he was waiting for Li Yuanxing's reaction.

Li Yuanxing said: "Didn't my brother go." ”

"Gorou came to Tianchi, is he here to see the martial arts competition, or to read the poems, or to enjoy tea?"

"Originally, I just wanted to come and have a look, but now I'm here to say hello to the royal brother!" Li Yuanxing smiled.

"Hello!" Li Er was puzzled!

Li Yuanxing stood up, stood up and handed the clerk to Li Er with both hands: "Congratulations to the imperial brother, our Li family has produced a fourth-class craftsman!" After Li Yuanxing finished speaking, Li Er's face sank, and besides, the fourth-class craftsman is noble, it is just the nobility of the commoners, for the royal family, who would want this craftsman level.

"Brother Huang, don't be angry first, it's not too late to see who gets angry again!"

Hum! Li Er snorted coldly, and said to Li Yuanxing while opening the paperwork: "Wulang, it's you who raised the craftsman too high. You ......" Li Er was about to accuse, but he was dumb, looked at the name on it repeatedly, and slapped a few cases beside him: "Okay, very good!" ”

"Ten years old, no longer a foolish child, he has grown up!"

"Reward, reward!" Li Er has more insight than Li Yuanxing, what is Li Su, in the future generations of bear children are also fleeing when they see him, he dares to cut people with a knife, dare to reach out and touch the palace maid, dare to steal something in the palace and go out to exchange money.

Li Su, although he is obsessed with craftsmanship, is much better than doing nonsense.

"Goro, I want to thank you for my brother!" Li Er's words are completely sincere. (To be continued......)
