See you soon Douluo

Chapter 114 Return
  On the World's End, according to Cheng Ying's calculations, most of the planets have been circumnavigated. Because of the stamping ability of the storage soul guide, nearly perfect gears and springs can be made, so that the accuracy of the navigation clock can finally be used. Longitude was 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 circumnavigation.

It stands to reason that there should be another continent, which was mentioned in Douluo Part 3, but Cheng Ying did not encounter it on his route, perhaps because it was in the southern hemisphere.

However, this cannot be seen from the description in the original work, which is normal. After all, in most novels, who has no time to go to the southern hemisphere! Anyway, Cheng Ying has never read any novel where the sun rises in the east and sets in the west, but is not in the south at noon...

As the World's End cruises along, it also improves along the way. The combination of soul guidance technology and mechanical technology keeps Chengying always in a state of technological explosion.

After returning to the mainland, with the perfect processing accuracy of the storage soul guide stamping, it is completely possible to process a perfect sealed reaction pool. In theory, the front-end technology of ammonia synthesis can be used to build high-pressure sealing equipment for submarines.

This is an extremely important subject in the chemical industry. If we cannot find a way to convert nitrogen in the air into ammonia or nitrate, the acquisition of nitrogen will always be a big problem. At least nitrogen fertilizers for agriculture cannot be produced, and gunpowder is used. He can only rely on scraping the saltpeter from the toilet. Even if he scrapes the saltpeter from all the toilets on Douluo Continent, it won't be enough for Chengying to last long!
  Even if he is using high explosives, whether it is nitroglycerin or trinitrotoluene, it cannot be separated from nitrogen. Relying on nitrogen fixation by plants, it is a foolish dream to develop the chemical industry.

In addition to a series of chemical industries such as ammonia synthesis, alkali production, sulfuric acid production, etc., Chengying is also planning to build several fractionation towers. In the past, refining kerosene from petroleum was really a piece of cake, including gasoline, diesel, lubricating oil, asphalt, and so on. Industrial blood must always be extracted from here.

Internal combustion engines are 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 Cheng Ying.

As long as industrial blood can be supplied, gasoline and diesel engines will be available 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 nothing more than excessive products before petrochemical technology matures.

If you want to use steam power in the future, you have to wait until nuclear reactors come out. That sentence is indeed true. Human beings develop and develop, but they still have to boil water in the end.

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

The so-called technology tree without bottlenecks is actually electric energy. In fact, even in the primitive era, it was possible to make electric piles and hand-cranked generators. In fact, electric energy has no bottleneck at all, but historically, The application of this energy happened to be discovered relatively late.

Now that the conditions are in place, although it is not possible to popularize electricity in the mainland for the time being, mainly because there is not so much copper on hand, it is more than enough to power the End of the World.

The generator is actually not difficult. It is nothing more than cutting the magnetic field lines with wires and winding them with coils. It is easy to make an alternator. Driven by the 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 tungsten. This kind of ore is not particularly rare, but because we don’t know how to smelt it, no one has refined this metal before Chengying.

In fact, it’s not that difficult to refine it. When you encounter metal oxides that you can’t handle, you’re right to use hydrogen. If you can’t handle hydrogen, then it’s basically difficult for simple substances to exist in nature.

Because metal elements that hydrogen cannot handle will basically react with water, such as metallic sodium, and water is everywhere on the planet... In short, electric lights are not that difficult. Glass seems expensive in this era, but for those who have mastered it, Technical people are just daily necessities that can be mass-produced, the kind that won't hurt even if a large piece half a man's height is broken.

As a result, the World's End soon became brightly lit. Compared with dim candlelight or oil lamps, incandescent lamps were undoubtedly much brighter. Like a nouveau riche, Chengying filled the ship with light bulbs. At night it is as bright as during the day, it is simply light pollution moving on the sea.

At this time, many sea soul beasts were attracted and rushed up to give everyone a meal. Many soul beasts are phototactic, 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 lights are 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 moving light pollution was indeed extremely shocking, and even the crew members themselves couldn't help but feel an inexplicable sense of pride, because nothing could 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 lighthouses observing the coast. On the other hand, it will also increase the possibility of getting lost at night.

Fortunately, Chengying provides mental scanning, so you don't need to worry about the danger of running aground, you just need to move in the direction of the target as much as possible.

Cheng Ying leaned on the armchair in the cab, looking at the lights that flickered on and off due to unstable voltage, his eyes full of nostalgia.

Why is he obsessed with climbing the technological tree and building a civilization that is different from this era? Apart from self-protection, why not remember the past life?
  If you really can't go back, then try to find ways to make this place more like your hometown.

Cheng Ying cannot be like many senior time travellers, who forget all about his previous life when he arrives in another world, and only focus on improving his strength. Perhaps this is the softness hidden deep in his character! But who knows how decisive he can be when this trust is violated?
  The distant coastline gradually reaches its end, and the familiar continent is right in front of us...
