The hut is Lu Yu's workshop.

He rubbed his head and found that he had thought about some things a little simply.

Now, for example, he has hit one of his own bottlenecks.

Wheel!

Rubber is such a good thing, and when it's not used, few people will realize how important it really is.

Lu Yu had felt the bumps of those carriages, even the most luxurious carriages, with an aura formation underneath, were actually ...... It's not that smooth, either. Especially with the kind of road that the dog gnaws out...... To tell the truth, many elderly officials often die on the way home, because they can't stand this kind of bump and die hard.

Therefore, the people drove horse-drawn carriages to travel, and all the styles of horse-drawn carriages were actually similar.

Narrow and slender.

First of all, it must be narrow, and the two wheels should not be too far apart, otherwise...... It is very likely that one wheel is on top of the dirt bag, and the other wheel is in the dirt pit, and the overturn is called a miserable.

After the key is overturned, the horses will be frightened, not only will they not stop, but they will be faster, and even the best carriage will be dragged into sawdust, and the people in it will ...... Nature is even more miserable.

So be fine.

And it has to be long, because at least one person has to be as long.

Sitting in a carriage for a long time...... In fact, it is not sitting, but lying.

Even if it is thin, the carriage will still sway wildly from side to side while traveling, and ordinary people can't support their bodies with one hand, and no matter how good their waists are, they can twist into willow leaves.

So you can only lie down.

But even lying down, it's hard to travel.

If it is hollow and inflated, just like the kind of tire in Lu Yu's previous life, it will be countless times smoother.

Coupled with the suspension system, it can reduce the vibration a lot. But the most important thing is the tires.

Anyone who has skated on roller skating knows that the sport is actually the most terrifying ...... It's those small pebbles that don't seem to be much, and the bumps of a pebble can make people play a close flight.

Therefore, this was the simplest and most common thing in the previous life, but now it has become Lu Yu's most difficult existence.

He tried to replace it with cork, and then found that although cork has a good shock absorption function, it does not have a good rebound function, let alone a long distance, even if it is a distance of more than ten zhang, the shape will change greatly.

He also looked for some trees that could secrete gum, but after the sap was dried and formed, it was more like latex, and the wear resistance or something didn't even need to be considered.

In fact, before making the engine, Lu Yu thought about the problem of tires, but he always felt that there were many things in this world, and tires must be very easy to solve, so he first went to overcome the difficulty of the engine, but he didn't expect that the more seemingly simple things were, the easier it was to make people helpless.

"It's ...... What should I do?"

In the end, we had to put this aside, at least to get a car body first.

For this, he has been planning for a long time.

Carrying goods, over mountains, comfort, adapting to harsh climates, and even ...... Have some defensive features.

After thinking about it, Lu Yu found that his imagination was not as good as he imagined, and the more he designed, the more he found that the things he designed were more like the tanks he often 'played' in his previous life.

'● Newer, most √#快dF上. Cool ● 'Craftsman M\Net;¤

And then......

And he rejoiced.

Tank?

Then tanks!

At the very least, if you get a tank, the problem with tires will be solved!

All-metal tracks, this can be had, transmission belts, all-metal chains, this can also be had!

If you don't have to think about heat dissipation, then you don't have to think about the water circulation system.

Wear is not taken into account, so the lubricating oil circulation system can also be omitted.

The only thing to consider is oil and gas...... If those designers in the previous life saw it, I am afraid that they will be angry, because in fact, those are the most difficult things.

However, there are also some things that make Lu Yu unable to be satisfied and relieved, that is, the air conditioner.

Imagine, under the scorching sun, blowing a cold wind or something, how comfortable and windy is that?

A warm breeze in the middle of winter......

Well, this one can have it!

While polishing the white iron suspended in the air with the method of controlling things, Lu Yu sketched a more and more sound design drawing in his mind...... Part by part, gradually put together, and the huge tank he thought of was getting faster and faster.

In the past, he wanted to make cars, and the purpose was simple: to sell oil, which was now only owned by him.

Just like the sale of ironwood and black coke, there must always be an indoor stove to make people acceptable.

But after all, the car is a large item, even if Lu Yu simplifies it, it has an extremely high price, which is not acceptable to ordinary people or ordinary business travelers.

And this thing...... He really can't be the only one who makes it.

For example, if the products and consumables are all manufactured by one company, then the company will not be long-term.

Only monopolizing one of them, he chose consumables.

Cars can be imitated by people from other countries on the continent, and in his opinion, the speed of imitation should be fast.

After all, there are countless 'supermen' in this world, and many things that in previous lives required large machines to do, in this world, they can do it with their own hands, even with their feet.

Not to mention the delicate things, just a refining work, Lu Yu didn't believe that there was any machine in his previous life, which was more effective and efficient than the 'cultivation' in this world.

What they lack is technology, they have knowledge, but they really don't lack the means to turn these things into reality.

Why is it lacking? It's not because cultivation is so easy to use!

Getting from one place to another, there's nothing faster than 'flying'. Lu Yu had calculated that an Innate Saint Rank could reach at least thirty times the speed of sound in long-distance travel, and could freely change directions and angles.

This is only the initial level of the Innate Saint Rank.

Convenient, easy to use, and even invincible, this is Reiki, this is cultivation.

Therefore, there is no progress in this world, because cultivation is the most royal thing. As Lu Yu has been emphasizing, there is only one pursuit in the world that is the real 'science', and that is eternal life!

The science of the previous life really couldn't do it, and the cultivation was ...... OK!

With this thing, if it were Lu Yu, he wouldn't have developed any technology. It's like in his previous life, he had the Lonely River Cold Star, and he didn't know how to use the pistol for many years.

But after all, there are only a few people who can cultivate.

Just like the ironwood black coke, Lu Yu's target has never been these few, but the majority!

The most important thing is that even if everyone in the world is like Baibaolou, the escort goods can dispatch the masters of the Innate Saint Rank, then it is impossible for the masters of the Innate Saint Rank to carry thousands of catties of goods for ten days and half a month, right?

Still need transport, so there are carriages.

But horses need to rest after all, and cars don't need to be used, just give fuel, just change people to drive.
