The strongest engineering student in ancient times

After the matter of the crossbow and the wooden gun was settled, the Sixth Prince and the others couldn't bear it anymore and asked them about the tricycle and the moped.Because they have been really curious about this kind of car that can move without external force, it looks really interesting.

Of course, they will not show a very interested look and seriously ask the principle of this car.

After being informed by Qi Yibai of its practicality, the eyes of the sixth prince and General Qian lit up.

Not to mention other things, just say that every time the grain and grass are escorted, if this kind of tricycle can be used, how much faster can it be! !How can we be afraid of the shortage of food and grass during the war!

The most important thing is that now they can almost only rely on shipping in Yannan, which is far from enough to supply the circulation of goods from east to west.

Just hearing this, the Sixth Prince and General Qian knew that this tricycle was too practical.

He wondered:

"How many of these tricycles can you have? How much so-called drain oil can you have? If we buy it to transport grain and grass, how much drain oil will we need to consume?"

Qi Yibai heard the words, thought of his big thoughts, and simply said:

"If you want to transport grain and grass over long distances, I actually think you can make railways and long-drawn vehicles, a large vehicle that can transport 60 million shi at a time."

60 million shi? !

How much should this be? ! !

Neither the Sixth Prince nor General Qian could imagine such a capacity, even Chang Yunqing and the others were shocked when they heard this.

Wei Qing was afraid that Qi Yibai's shocking words would be easily suspected, but at the next moment Qi Yibai said:

"Of course, I can't make this kind of long car, but if the adults and the Holy One think that this kind of long car that can carry people and goods is necessary, you can let people come to me, I will do my best. Help those able people to make my idea, although there is no long dragon cart here, but this kind of long dragon cart is recorded in the ingenious things my master gave me."

The Sixth Prince and General Qian were at a loss, they didn't know what a dragon chariot was, but just listening to Qi Yibai's description, they knew how magnificent the dragon chariot would be if it was made,

It's just that such a thing really exists.

Qi Yibai also seemed to see the doubts of the Sixth Prince and General Qian, and said:

"In two days, I will show the concept to all the adults. By then, you should be able to understand what I mean. At that time, I will elaborate on the other uses of the dragon cart."

In fact, Qi Yibai has always wanted to build a few railways, running from east to west, from north to south.

Of course, he also knew that if the people in Yannan Kingdom didn't have enough to eat, everything would be empty. However, there are many plains in Yannan Kingdom, and the soil is fertile.

With the current strength of Yannan Kingdom, it is not difficult to build a railway, so it is still possible. If the railway can be built, he believes that the economy of Yannan Kingdom can develop faster.

The Sixth Prince and General Qian didn't know what Qi Yibai was thinking, but he really wanted to know what kind of shape the dragon car that Qi Yibai was talking about was early on, and what was so magical about it being able to carry it all at once. 60 million shi of goods.

None of them went back to Shuixi County with Magistrate Xiao, but stayed here, waiting impatiently.

Seeing this, Wei Qing asked Chang Yunqing to take them around, and then taught them how to learn bicycles and mopeds. As long as they learned how to bicycle, the mopeds would be at their fingertips. It only took a day or two for them to learn. Bicycles and mopeds, the feeling of being able to control the front of the car by themselves is so fresh that they almost forgot the purpose of coming all the way to Shuixi County this time.

Every time the Fifth Prince Xida saw them riding bicycles, he would be very angry. The imperial envoy of Yannan Kingdom was simply playful, and it was too much to let him go to work in the mountains every day, but he was happy here, waiting for his father. To take him back, he must send a copy of these imperial envoys to the king of Yannan Kingdom! !

The fifth prince Xida became more and more angry as he thought about it, so he went directly to the sixth prince and told him that he wanted to ride this bicycle too, otherwise he would definitely join him for a copy.

The sixth prince was not afraid, after all, he was the younger brother of the emperor's mother and compatriots. General Qian and Qiu Shilang were a little worried, so they proposed to learn together, anyway, the fifth prince Xida probably wouldn't be able to learn.

When the Sixth Prince, General Qian, and Qiu Shilang were still riding bicycles, Qi Yibai had already drawn the simple trains and railways, and even sketched the approximate power principles of the trains on it.

When he came to find the Sixth Prince and the others, he saw them riding a moped, and tried to ask Chang Yunqing to take them to the town on a moped.On the other hand, the fifth prince Xida said angrily that they had to take him with him, otherwise they would be abusing the royal family. It seems that the fifth prince Xida has been getting more and more insatiable in the past two days.However, the Sixth Prince and General Qian refused righteously and told him to continue working after learning how to ride a bicycle.

Chang Yunqing was also in a dilemma, if something happened to the imperial envoy in the town, they would all suffer.

Fortunately, Qi Yibai showed up in time to talk about the dragon car.

Because there are simple drawings this time, it is easy to understand why the long dragon cart can carry 60 million stones at a time. General Qian asked in shock:

"Then if we keep adding carriages at the back, wouldn't we be able to carry endless cargo?"

The Sixth Prince and Qiu Shilang also nodded when they heard the words. This long dragon cart is really amazing, and I don't know what kind of god Mr. Wei's husband Lang's master is. He can even think of such a thing as a long dragon cart. No surprises.

Qi Yibai thought in his heart that General Qian's thinking was quite beautiful.

He took the opportunity to explain the power problem of the train. It cannot pull so many goods, and the longer it is, the more unstable it is. It is easy to derail and overturn. If the train derails and overturns, it is not so easy to deal with now.

Hearing this, they nodded hurriedly, so that's the case, they said, if the long dragon car can really connect to the endless carriages, it is definitely an existence that is against the sky.

After clearly realizing the role of the long-drawn chariot, whether it is the Sixth Prince or General Qian, don't mention how excited he is. This alone, if he returns to the capital, will definitely cause an uproar, and he doesn't need to doubt at all that this long-drawn chariot , the emperor will definitely let it be built, because the effect is too great. Not only can it transport all kinds of war materials in time, but it can also do the most important thing, that is, the speed of reinforcements! !

Once there is a shortage of troops, they can start immediately, and it only takes a few days to achieve the purpose of reinforcements. This kind of good thing, it is estimated that a fool can know how good the dragon car is.

The Sixth Prince liked what Qi Yibai said very much, it can carry a lot of people and goods when they usually travel, and it can definitely effectively promote the exchange of goods.

The Sixth Prince did not expect that he would gain such a big gain when he came to Shuixi County this time. If he brought these bows and wooden spears back, those officials would probably be shocked into fools.Thinking of this, he wanted to put on his wings and fly back to the capital immediately.He doesn't even mind putting aside the matter of getting along with Wei Yuan.

If it wasn't for the Fifth Prince Xida's presence again, the Sixth Prince really almost forgot to deal with the Fifth Prince.

When mentioning the Fifth Prince Xida, the Sixth Prince looked at him with distaste. A dignified fifth prince, who didn't pursue him so much, knew that he was pestering him to ride a bicycle. He couldn't recognize himself as a prisoner at all, so he said It's really a shame to join him for a book.
