Xu Xian was polite, and then carefully looked at the model train that had stopped. Pen & Fun & Pavilion www.biquge.info

His mind spun quickly, the knowledge stored in his brain was very rich, it was an encyclopedia, another time and space of scientific and technological civilization, and the principle knowledge of everything was basically copied into his brain.

If it weren't for the fact that this is a world of cultivating immortal civilization, without a little scientific and technological foundation, he would have directly taken out some high-end inventions, but unfortunately, with these foundations now, even if he takes them all out, it is impossible to really create real things, and he may be regarded as a fool and a madman.

But the steam engine and the steam engine-powered machinery can still be taken out.

If once he can produce it in large quantities, but it can affect the lives of countless ordinary people in this world, the merit he will get at that time is not enough to describe it.

Xu Xian squatted down and took a closer look, feeling that many things were still very rough made, so he stood up and said with a smile: "I'll just say a little casually, it's just my opinion, I just have some ideas, if you really let me do it, then I can't do it by hitting the south wall." ”

Then Xu Xian pointed out some of the deficiencies according to the knowledge in his mind and according to the comparison, of course, he also noticed that many things are not achieved overnight, and it takes some time to accumulate and slowly improve.

For example, the sealing problem of the boiler, how to improve the power output, and the problem of the rails, it is recommended to let them get sleepers and gravel under the rails, which can distribute the pressure, not easy to go wrong, and can also reduce the problem of the rails getting stuck in the mud.

There is also the purpose of the train in the future, and how to pick up a few more carriages in the back, or sit or pull goods, he said what he knows to pick up some easy to do.

The silence of the surrounding crowd was terrifying, and they all listened carefully, and the old people of several families did not think that Xu Xian was a liar, and the real example was in front of them.

The most important thing is that this train did not use a little mana, but it could emit such a strong force simply by relying on some coal, which means that even ordinary people can do a lot of things in the future.

"Of course, I don't think this wagon is the best, with the development of time, we can slowly improve, maybe in the future, we can even make the train less noisy and faster, which requires thousands of people to accumulate and improve little by little, I also occasionally think of an idea.

I also saw a carriage not far away just now, and now the carriages are no longer only two wheels, and if a few horses in the carriage are turned into a huge train and pulled by him, wouldn't that be what I just said that it can pull people and goods? ”

Everyone was still a little suspicious that when Xu Xian pointed to the carriage in the distance and explained it again, they all suddenly realized that Xu Xian was not an immortal, but remembered it at a moment's notice.

"Of course, I believe that there will be a lot of problems in the future, if you want to really build a train and make it possible for ordinary people to use it, maybe for many years, today, I have brought a simple means of transportation, suitable for ordinary people to use for short distances. ”

Xu Xian said and took out a model from his arms, which was a model of a bicycle.

Xu Xian cast a spell to make the model of the bicycle vivid, and replaced the somewhat difficult car chain with a rope, it is a little difficult to produce a car chain under today's conditions, but he still made one, whether he can really make it, it depends on these people in Luban Academy.

"Lu Lao, I don't know if I can make such a big real car according to my model?" Xu Xian handed the model to Lu Lao and asked tentatively.

"It's easy for me to make one, but if I let ordinary people do it, I'm afraid it will take some time, you guys wait a while. Lu Lao didn't speak, and soon went to a small dark house on the side of the square, and came out of it in less than a quarter of an hour, just carrying a beautiful bicycle in his hand, all made of iron.

Xu Xian smiled, and said a little embarrassed: "Old Lu, I still have to trouble you once, can you make the wheel lighter, and then put an elastic thing on the wheel." ”

Lu Lao didn't ask why, and continued to do so, and soon a changed bicycle came out.

Just watching Lu Lao carry the bicycle on his shoulder, Xu Xian wanted to laugh, but held back.

Xu Xian took the first bicycle and tried it, and it was still very strong, that is, the conveyor belt was very strong.

He tried to ride it, it felt a little heavy, but it was still faster than running, and it was not very tired, Xu Xian was interested for a while, riding this unique bicycle, racing around the square, and the people around him were all speechless, so they wanted to see something extremely shocking.

Xu Xian finally came to Lu Lao's side and said: "I feel that it can be improved, now it is a little heavy, maybe the weak body will not ride for a long time, you can come and try, I think it will be much more convenient for everyone to walk back and forth in the future." ”

As soon as Xu Xian's words fell, dozens of bicycles were thrown out of the hut next to the square, followed by Shen Congxing, and the whole person was happy.

"I've got dozens of them to try. ”

Shen Congxing's dozens of cars have been improved again, which is better than the original one, and for a while many people rushed to ride bicycles, and bicycles became popular in Luban Academy because they were too convenient.

Then it became popular in Suzhou, and then it spread to the whole country, which made several families earn a lot of money, and Xu Xian also earned countless silver, and more importantly, he got closer to several families.

After understanding, Xu Xian learned that these families were all cultivation families, and there were even legends that some of the predecessors of the families even soared to the heavenly realm and became immortals.

"After all, this is a world dominated by immortal cultivation civilization, I don't know if I can carry forward the scientific and technological civilization and form a trend. Xu Xian sighed in his heart on the way back.

The reason why Shen Congxing and the others were able to get a lot of bicycles so quickly was because they were cultivators in the Exorcism Realm and even the Manifestation Realm.

In this world, everything is related to cultivating immortals, so no matter what you do, you must first have a good relationship with the person who cultivates immortals, which is possible.

"I can only try my best to let the immortal cultivation civilization in this world slowly integrate some scientific and technological civilizations, and I don't know what kind of new civilization will be formed, and now it can be regarded as the beginning of a new civilization, right?"

Xu Xian touched his chin, and a smile appeared on his face.
