Global Wasteland: Unlimited Upgrades for Vaults

"Why think so far, let's wait until I find more information about the last disaster!"

Ma Gu's information has brought too much convenience, and Su Mo was also very curious about the final outcome of the last time it was put into humans.

Opening the friend panel, finding a friend whose profile picture had been hacked, Su Mo conveniently created a fourth account for recording.

"This account is temporarily used to record some plans for the future!"

After writing this sentence, taking advantage of his spare time, Su Mo began to think about the plan after the disaster.

According to Magu's diary, if there is really a long recuperation period after the snow disaster, Sumo decided to take the initiative to attack the outside world.

At least one must fully explore the underground shelter within 300 kilometers!

take a day off

During the May Day Golden Week, my friends came to travel today. As a "local", I have to entertain them. I will make up for it for a day, and I wish you all a happy May Day~ I love you!

Chapter 168 Global popularity, the bullet is finally completed!

The wind was still blowing, and the snow was still falling. Sitting in the wind and snow, Su Mo could see more things that he had forgotten due to his haste for many days.

For example, in the storage space, there are three sets of brand new cotton clothes.

For another example, the snowflakes, clouds, and strong winds in the sky play their own roles without interfering with each other, forming a very strange climate.

Of course, there are also thoughts brought about by examining other lone wolf shelters.

All the current "lone wolves", including the number one shelter, also rely on terrain to build shelters.

Few, or more and more, are choosing to ditch the homes created with game panels in favor of building their own shelters.

"In addition to chatting and trading secret realms, most people have already begun to find ways to get rid of the game panel"

"But that's right, if humans put all their focus on the game, they will always be stuck in the neck!"

Abandoning the shelter built by the game panel does not only mean losing the functions in the game such as "upgrade", "extraordinary blessing", "extensibility"...etc.

At the same time, some modular technologies that may be touched in the future will also be constrained, seriously affecting the speed of development.

This is why even large shelters should maintain several play houses.

The first update, axed the crafting system and added most of the restrictions, including pay-to-use crafting.

And there are also payment restrictions on private message chats.

It is precisely because of this update that most people lose confidence in the game panel and choose to try to get rid of the control of the game.

After all, if one day the shelter I upgraded is recycled, wouldn't it be a sudden death!

Even Su Mo didn't think much about this point, but now it has become more and more exaggerated in the mouths of some "conspiracy theorists".

"Games, systems, individuals, races..."

Carefully pondering the connection between these nouns, trying to think about the points that might be involved, Su Mo didn't realize that such a long time had passed until his stomach growled at noon.

The "storm" during the day is not strong, which also gives all creatures living on this land a chance to breathe.

Seeing that Oreo was still sleeping in his arms, Su Mo simply walked down the hillside, returned to the tool table, pulled out a few wooden boards, and built a small nest at the door of the garage that could accommodate Oreo.

Big and small sparks also cooed and followed up at this time, seeing Oreo laying motionless on the ground, trotted over anxiously, lying beside Oreo and calling.

"It's okay, you two look at it, just call me if there is any situation!"

The temperature on the first floor of the shelter was frighteningly low, especially when the garage door was opened, the cold wind came in, even with combat uniform, Sumo was shivering from the cold.

It wasn't until I returned to the second floor, took out the brand new cotton-padded clothes and trousers and put them on, and turned on the heater around my waist, that I felt much more comfortable.

Oreo needs to be cold. Sitting in the base, Sumo can't turn on the air conditioner to heat up. He can only sit in front of the workbench and forcefully concentrate on continuing to study the technology tree for upgrading weapons and ammunition.

The prepared nitrocellulose in the storage space, also known as nitrocellulose, is extremely safe.

After nearly a day of collecting and knocking out the vinyl in the well, Sumo began to think of ways to make the last two important items--

Ethanol, ether!

Ethanol production is developed on the basis of winemaking.

As far back as ancient times, people had already fermented starchy substances to make wine. In the 12th century, when distilling wine, it was the first time that alcohol was separated from wine.

Until the 20s, fermentation was the only method of industrial production of ethanol.

Until around 1930, Union Carbide Corporation established the first industrial device that used ethylene, a by-product of thermal cracking of petroleum, as raw material, absorbed by sulfuric acid and then hydrolyzed to produce ethanol.

This well-known indirect hydration method of ethylene is convenient and simple, and has significant advantages. Once it appeared, it became the best method for preparing ethanol.

There is a large amount of high-purity sulfuric acid in the refuge, and it is impossible to go out in heavy snow. After eating some pancakes to restore his strength, Su Mo began to concentrate on making.

It didn't take long for a large amount of ethanol to be prepared.

As for the production of ether, it is even simpler. According to the reaction formula, to prepare ether, you only need to break the oh bond and the co bond to complete it.

With a large number of experimental instruments and the roads stepped by the predecessors, the biggest difficulty in smokeless gunpowder is actually the suitable "cotton".

As for the diphenylamine used to configure the stabilizer, it only occupies a small amount in the smokeless powder.

After some research and found that the price of the system was not expensive, with a wave of his hand, Su Mo bought enough to prepare 20 rounds of ammunition for only [-] survival points.

"pressed...cut into strips...dried...hardened"

Step by step, Su Mo worked extremely patiently and completely followed the concept of scientific preparation. Until the evening, all the gun cotton was finally made!

The smokeless gunpowder neatly cut into strips is placed on the workbench, no matter from which angle it is viewed, it has a different aesthetic feeling.

After working for many days, Su Mo's hands have become a little rough.

Especially touching on the smokeless gunpowder, the feeling of friction is more intense.

"Smokeless gunpowder! It's something that hasn't been researched for centuries, but it only took me one day from the beginning to the completion!"

Standing on the shoulders of giants and looking at the world, at this moment, Su Mo was extremely grateful for the knowledge he had received intentionally or unintentionally in the peaceful age.

It may be a novel, it may be an answer to Zhihu, or it may even be a marketing account mixed with a lot of useless information.

These information streams constitute the huge knowledge reserves of modern people, which can be quickly transformed into "strength" after coming to the wasteland of the end of the world!

With a modular machine tool, there is no need to wait until all the smokeless gunpowder is completely dry and hardened.

3000 bullets require 18 units of copper and 2 units of lead.
