As a last resort, Li forgets worry and is unwilling to ask Cheng Yaojin.

After all, although Cheng Yaojin didn't know why he was close to him, Li forget worry didn't think he should rush to the door for help.

Moreover, the black man is still stubborn. He feels ashamed to come to ask Cheng Yaojin for help. Even if Cheng Yaojin came forward to stop Li's plot this time, what about the next time? Does he beg Cheng Yaojin every time?

Li forgot to worry and paced back and forth in the main room, wondering how he should face it.

According to Yang Zuan, although the rank of Chang'an County household joining the army is not high, it is his authority to recruit civilian men to transport grain, and once the matter is settled, Dingzhou village must be completed.

If the corvee cannot be completed, the punishment is very severe. It is possible to beat the board and go to jail or even prisoners. Li forgets worry and doesn't think he can resist the government.

Then the only way is to find a way to transport the 1000 stone grain to Yinzhou.

However, he just asked Yang Zui that there is no waterway in Yinzhou, so shipping is impossible. The only way to transport is by land, using ox carts or carriages.

With the current ox cart transportation capacity of Datang, that's it. The carriage is faster, but the load capacity is not good.

He slapped his head depressed, hoping to come up with a solution to the current dilemma.

Su Changqing looked worried: "forget your worries. Don't think about it. You'd better go to Uncle Cheng and beg for mercy."

Li forgot to worry and thought for a long time. He really felt that there was no other way. He could only sigh and nod silently.

He told Niu Wu to lead the horse. They rode and were ready to go to Chang'an City for help.

Shortly after leaving the entrance of Dingzhou village, a carriage came up. Because the road was not wide, Li forgot to worry and stood aside with Niu Wula Ma, waiting for the carriage to pass first.

The carriage squeaked past them, and the handlebars nodded to them in a friendly way to thank them.

After the carriage, as soon as Niu Wu pulled the reins, he was ready to urge the horse to move forward, but he saw Li forgetful sitting motionless on the horse's back, staring at the fading carriage and thinking about things.

"Lang Jun, what are you thinking? Let's go." Niu Wu urged.

Li forgot to worry but didn't speak, just in a daze.

When Niu Wu was wondering, he saw Li forget worry and suddenly pull the reins: "Niu Wu, let's go back! I have a way! Ha ha, I'm really a genius!"

Without waiting for Niu Wu, Li forgot to worry and ran to the village. Niu Wu was baffled and had to turn his horse's head to follow up.

Seeing that Li forgot his worries and returned, the beautiful boss couldn't help wondering, "forget your worries, how did you come back?"

Lao Cun Zheng and Yang Zuo were still in the Li family hall. They were surprised to see him suddenly return.

"Ha ha, Changqing, I have a way! As long as a four-wheel carriage is built, this 1000 stone grain is not a problem!" Li forgetful jumped off the horse and shouted.

"Four wheeled carriage?" Su Changqing didn't understand what he meant.

Lao Cun Zheng and Yang Zuo were also confused by Li's words. What is this four-wheel carriage?

Since ancient times, there have been few four-wheel carriages in China. In the Song Dynasty, there have been four-wheel carriages, such as the picture of the river during the Qingming Festival.

However, that kind of four-wheel carriage is different from those in the West. Its four wheels are installed on a fixed frame, so it can't turn. The turning problem is solved by four cows with great strength.

Yes, this is the reason why Chinese carriages and ox carts have two wheels since ancient times. No bogie has been invented!

Since Roman times, four wheeled carriages with bogies have appeared in the west, while the East has indeed taken a detour in this regard.

Just now, when Li forgot to worry about the Datang carriage, he always felt something was wrong. After thinking about it for a long time, he suddenly realized that it was because the Datang carriage and ox cart had only two wheels.

In terms of load, the four-wheel carriage is the best of the two-wheel carriage.

Li forgets to worry about remembering that in those days, the European Napoleon Corps solved the problem of military transportation by means of four wheeled carriages. At that time, each carriage pulled by four horses had a load of up to 1.5 tons!

It is equivalent to a four-wheel carriage that can carry 30 stones of grain, and a thousand stones of grain, but more than 30 four-wheel carriages can be easily pulled away.

Moreover, the carriage pulled by four horses is much faster than the ox cart.

The ox cart can only walk seven or eight kilometers per hour, while the speed of the carriage can reach about 20 kilometers. According to the four hours a day, that's 160 kilometers. It's only about three days to go from Chang'an city to Yinzhou.

"Mingfu, when will the household join the army and let us start?" Li forgetful asked. He needed time to summon people to trial produce the carriage.

"Five days later, start from Chang'an city."

"Can the cattle carrying grain be replaced by horses? I need more than 100 horses." Li forgetful asked again.

Yang Zuan frowned: "of course. After all, cattle are more expensive than horses. Do you want to transport grain by carriage? Horses are not as strong as cattle."

"Yes, Xiao Lang, you can't joke about this. The carriage can only pull five or six stones of grain, and the ox cart may pull ten stones closer. If the carriage is used, there will be more people in the village who need to be dispatched, which can't be used." old village Zheng also hurriedly advised.

"Ha ha, don't worry. I can build a carriage to pull thirty stone grain! I'll go to carpenter Liu now!" Li forgets worry, and then turns and runs out.

His words made Yang Zuo and the old village look at each other. Didn't the little Lang of the Li family get mad?

A carriage pulls thirty stone grain? How is that possible!

Even an ox cart pulled by four cows can't carry so much, let alone a horse.

"Ming mansion, you look at things..." old village Zhengqi AI looks at Yang Zui and hopes he can persuade Li to forget his worries.

This matter is related to the life and death of Dingzhou village, but it can't be fooled by the temperament of Li Xiaolang.

But the beautiful boss on one side understood Li's words and couldn't help brightening his eyes. Although she didn't know how much goods the four-wheel carriage could carry, she knew that the four-wheel carriage eliminated two carriages, and she also did that kind of four-wheel carriage when she traveled abroad in the future.

Two horses can pull more than a dozen tourists around, which is much better than the ox cart in Datang.

Yang Zuan and Lao Cun Zheng naturally didn't know this. After Li forgetful ran out, they were also restless. They couldn't understand what Li forgetful wanted to do.

Just let the old village lead the way, and they also walked to carpenter Liu's house, ready to see with their own eyes what Li forget worry's "four-wheel carriage" is.

At carpenter Liu's house, Li Qieyou was busy writing and painting on paper with a charcoal pen. While writing and painting, he said something to carpenter Liu. Carpenter Liu's three sons were also watching.

Yang Zuo and Lao Cun Zheng didn't know, so they had to stand by and watch. After a long time, Li forgot to worry and finally put down the charcoal pen. Carpenter Liu and his three sons were excited.

"Xiao Lang, if you are really a Wenqu star from heaven! You know these gods! I will try it with my son right away. If you succeed, Xiao Lang, you will make a great contribution to the benefit of all the people!" sighed carpenter Liu.
