Douluo See You For a Long Time

On the World's End, according to Chengying's calculations, most of the planets have been circled. Because of the stamping ability of the storage soul guide, it can produce almost perfect gears and springs, so that the accuracy of the nautical clock can finally be used Longitude is measured.

They are now not far from the east coast of Douluo Continent. At that time, they only need to go south, bypass the Star Luo Empire, and return to Doujiang along the coastline to complete their first round-the-world voyage.

It stands to reason that there should be another continent, which was mentioned in the third part of Douluo, but it was not encountered on Chengying's route, perhaps because it is in the southern hemisphere.

But from the description in the original book, we can't see this point, which is normal, after all, most of them, who are free to go to the southern hemisphere! Anyway, Cheng Ying didn’t read any of the scripts where the sun rises in the east and sets in the west, but it’s not in the south at noon...

The End of the World has been driving all the way, and it is also improving along the way. The combination of soul-guided technology and mechanical technology makes Chengying always in a state of technological explosion.

After returning to the mainland, with the perfect processing precision of the storage soul guide stamping, a perfect sealed reaction pool can be processed. In theory, the pre-technology of synthetic ammonia can be used to build high-pressure sealing equipment for submarines.

This is an extremely important subject in the chemical industry. If you cannot find a way to convert the nitrogen in the air into ammonia or nitrate, the acquisition of nitrogen will always be a big problem. At least the nitrogen fertilizer in agriculture cannot be produced. The saltpetre can only rely on the toilet to scrape the saltpeter, even if all the toilets on Douluo Continent are scraped, it will not be enough for Chengying to use it for a long time!

Even if he is using high explosives now, whether it is nitroglycerin or trinitrotoluene, nitrogen cannot be separated. Relying on nitrogen fixation by plants, it is just a dream to make the chemical industry develop greatly.

In addition to ammonia synthesis, alkali production, sulfuric acid production, and a series of chemical industries, Chengying is also planning to build several fractionation towers. Previously, refining kerosene from petroleum was really a trivial matter, gasoline and diesel, lubricating oil, asphalt, etc. Industrial blood is always extracted from here.

The internal combustion engine is no longer a problem. The basic structure of this thing can be found in junior high school physics books. It is much more detailed than the structural 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 engines and diesel engines can be launched immediately. History has proved that steam engines will be eliminated sooner or later. Although steampunk is romantic, it does not adapt to the times and will be abandoned by the times.

The current steam engine, steam locomotive, steam spinning wheel, and even steam engineering machinery are just excessive products before petrochemical technology matures.

If you want to use steam power in the future,

Then we have to wait for the nuclear reactor to come out. That sentence is indeed true. Human beings develop and develop, and eventually they still have to boil water.

During the period when he was about to return to the mainland, Chengying also lit up some technology trees that had no bottlenecks at all, in order to make this return even more shocking.

The so-called technology tree without bottlenecks is actually electrical energy. In fact, even in the primitive era, it is possible to produce electric piles and hand-cranked generators. In fact, there is no bottleneck in electrical energy, but in history, The application of this energy just happened to be discovered relatively late.

Now that we have the conditions, although it is temporarily impossible to popularize electricity in the mainland, mainly because there is not so much copper on hand, it is more than enough to supply power to the end of the world.

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

With electricity, it is natural to use electrical appliances. Naturally, the first thing that comes to mind must be electric lights. Talking about mobile phones is too much!

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

In fact, it is not too difficult to really refine it. When encountering uncertain metal oxides, it is right to use hydrogen gas. If hydrogen gas is uncertain, it is basically difficult for elemental substances to exist in nature.

Because the simple metals that hydrogen can’t handle will basically react with water, such as metal sodium, 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 kind of daily necessities that can be mass-produced. The kind that breaks a large piece that is half the height of a person will not feel distressed. .

As a result, the lights on the World's End soon became brighter. Compared with the dim candlelight or oil lamps, the incandescent lamps were undoubtedly much brighter. Like an upstart, Chengying filled the ship with light bulbs. At night, it is as bright as daytime, and it is simply light pollution moving on the sea.

At the end, many sea spirit beasts were attracted to rush up to give everyone extra meals. Many spirit beasts are phototropic, which is good. When the lights are turned on at night, even the bait is saved.

Although Chengying's arrangement is extremely vulgar, it has to be said that lighting is indeed a symbol of civilization, just like the earth in Chengying's previous life. When viewed from space at night, the more prosperous the place, the brighter the light. Bright.

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

In fact, it is very unscientific to turn on the lights so brightly at night. On the one hand, it will affect the observation of the lighthouse on the coast, and on the other hand, it will also increase the possibility of getting lost at night.

Fortunately, there is Chengying to provide a mental power scan, so you don't need to worry about the danger of hitting the rocks, you just need to move towards the target as much as possible.

Chengying leaned on the armchair in the driver's cab, looking at the lights that were flickering due to unstable voltage, his eyes were full of nostalgia.

Why is he obsessed with climbing the technology tree and building a civilization different from this era? Except for self-protection, isn't it a memory of the previous life?

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

Chengying couldn't do like many senior traversers who forgot all about his previous life when he arrived in a different world, and only focused on improving his strength. Perhaps this is the softness hidden deep in his character! But who knows, how can he be decisive when this sustenance is violated?

The coastline in the distance is gradually coming to an end, and the familiar continent is just around the corner...
