Douluo See You For a Long Time

, The fastest update Douluo will see the latest chapters for a long time!

On the end of the world, according to Chengying’s calculations, it has already bypassed most of the planet. Because of the punching ability of the storage soul guide, it can make almost perfect gears and clockwork, so that the accuracy of the marine clock can finally be used Measure the longitude.

They are now not far from the east coast of the Douluo Continent. By then, they can return to Doujiang along the coastline by heading south, bypassing the Xingluo Empire, and completing their first round-the-world voyage.

It stands to reason that there should still be a continent. This was mentioned in the third part of Douluo, but it was not encountered on the route of Chengying, perhaps because it was in the southern hemisphere.

However, from the description in the original book, I can't see this. This is normal. After all, most of them, who ran to the southern hemisphere without a problem! Anyway, Chengying didn’t look at any one that says the sun rises in the east and sets in the west, but it is not in the south at noon...

The end of the world is improving along the way as it travels all the way. The combination of soul guidance technology and mechanical technology makes Chengying always in a state of technological explosion.

After returning to the mainland, the perfect sealing reaction tank can be processed with the perfect processing accuracy of the storage soul guide stamping. Theoretically, the front technology of synthetic ammonia is an anti-high pressure sealing device that can be used to build submarines.

This is an extremely important subject in the chemical industry. If you can’t find a way to convert nitrogen in the air into ammonia or nitrate, the acquisition of nitrogen will always be a big problem. His saltpeter can only rely on the toilet scraping, even if all the toilets on the Douluo Continent are scraped, it will not last long enough!

Even if he uses high explosives now, neither nitroglycerin nor trinitrotoluene can be separated from nitrogen. Relying on plants to fix nitrogen, it would be a idiot to want the chemical industry to develop.

In addition to synthetic ammonia, alkali production, sulfuric acid production, and a series of chemical industries, Chengying is also preparing to build several fractionation towers. Before refining kerosene from petroleum, it was really a trivial matter. Gasoline, diesel, lubricating oil, asphalt, etc. Industrial blood is always refined from here.

The internal combustion engine is no longer a problem. The basic structure of this thing is available in the junior high school physics book. It is much more detailed than the structure diagram of a steam engine. Let alone a normal four-stroke cylinder engine, even a rotary engine can be designed by Chengying.

As long as industrial blood can be supplied, gasoline and diesel engines can be launched immediately. History has proven that steam engines will be eliminated sooner or later. Although steampunk is romantic, it will not adapt to the times and will be abandoned by the times.

The current steam engines and even steam locomotives, steam spinning wheels, and even steam engineering machinery are just excessive products before the maturity of petrochemical technology.

If you want to use steam power in the future, you have to wait for the time when the nuclear reactor comes out. The saying is true. Human beings develop and develop, and ultimately they have to boil water.

During the time when he was about to return to the mainland, Chengying also lit up some science and technology trees that had no bottleneck at all, so that this return could be even more shocking.

The so-called technology tree without bottlenecks is actually electric energy. In fact, even in primitive times, it is possible to build a stack or a hand-cranked generator. There is no bottleneck in electric power. It is just in history. The application of this energy happened to be discovered relatively late.

Now that the conditions are available, although it is not possible to spread electricity to the mainland for the time being, mainly because there is not so much copper on hand, it is more than enough to supply the world's top power supply.

The generator is actually not difficult. It is nothing more than the wire cutting the magnetic induction wire. It is easy to make an alternator by winding it with a coil. Driven by a steam engine, it can easily power the entire ship.

With electricity, it is natural to use electrical appliances. Naturally, the first thing that comes to mind is definitely the electric light. It is too much to talk about mobile phones!

As we all know, the most suitable material for incandescent lamps is metal tungsten. This kind of ore is not particularly small, but because I don't know how to smelt it, no one has ever extracted this metal before Chengying.

In fact, it is not too difficult if you really want to refine it. When you encounter metal oxides that you can't handle, you can get hydrogen. If you can't handle hydrogen, it is basically difficult to exist in nature.

Because the elemental metal that hydrogen can't handle will basically react with water, such as sodium metal, and the planet is full of water...

In short, the difficulty of electric lights is not great. Glass seems to be expensive in this era, but for those who have mastered the technology, it is just a commodity that can be mass-produced, and it will not be distressed to break a half-person tall piece. .

As a result, the world’s end station soon became brightly lit. Compared to dim candlelight or oil lamps, incandescent lamps were undoubtedly brighter. Cheng Ying was like a nouveau riche, filling the ship with light bulbs. At night, it is as bright as daytime, and it is simply light pollution moving on the sea.

At that time, a lot of sea spirit beasts were attracted to rush up to give everyone a meal. Many spirit beasts are phototaxis. This is not the case. When the light is turned on at night, even the bait is saved.

Although Chengying’s arrangement is extremely vulgar, it has to be said that the light is indeed a symbol of civilization, just like the earth of Chengying’s previous life. At night, when you look at it from space, the more prosperous the place, the brighter the light. Bright.

And this moving light pollution is indeed extremely shocking, and even the crew themselves can't help but feel an inexplicable sense of pride, because nothing can be brighter than them at night.

In fact, it is unscientific to turn on the light so bright at night. On the one hand, it will affect the lighthouse for observing the coast. On the other hand, it will increase the possibility of getting lost at night~www.NovelMTL.com~ Fortunately, there is a psychic scan provided by Cheng Ying. , You don’t need to worry about the danger of hitting the rocks, you just need to move in the direction of the target as much as possible.

Cheng Ying leaned on the backrest of the driver's cab, looking at the indefinite light because of the unstable voltage, her eyes were full of nostalgia.

Why is he obsessed with climbing the tree of science and technology, obsessed with building a civilization different from this era? Except for self-protection, why not remember the previous life?

If you really can't go back, then try to make this place more like your hometown.

Chengying couldn't do the same as many traverser predecessors. When he arrived in another world, he would completely forget his last life. His whole mind was only to improve his strength. Maybe this is the softness hidden in the depth of his character! But who knows how he can be decisive when this sustenance is violated?

The distant coastline gradually came to an end, and the familiar continent was in sight...
