Train Survival: I Know My Luck

Then Yu Qian'an used the second upgrade scroll on the howitzer. If he just felt that it was necessary to upgrade the weapon, Yu Qian'an might hesitate for a while, but Yang Jiarui also said that he wanted to upgrade the weapon, so it was very necessary.

After the upgrade, the caliber of the blue one did not change, it was still 40 mm, but the range increased, directly soaring to 1,500 meters, the theoretical rate of fire was 800 rounds per minute, and the actual rate of fire was still 60 rounds per minute, which looked the same as when it was green.

But in fact, the 60 rounds refers to 60 rounds per minute when firing blue grenades. If it is changed to green, at least 180 rounds can be fired, and when firing white grenades, it can directly reach 300 rounds per minute.

With this firing frequency, Yu Qian'an can directly use this howitzer as a heavy machine gun.

Get more bullets, and it is no problem to block the charge of tens of thousands of people!

Then there are blue glass manufacturing drawings. Yu Qian'an is still very curious about this glass that can be used as a solar panel.

Glass manufacturing blueprint (blue) x1 (permanent) Manufacturing materials:

Silica sand (blue) x1

Glass (green) x1

Lithium ore (blue) x1

Silver (green) x1

The required materials are not many, but both are blue, and lithium ore is something I have never seen before.

Yu Qian'an feels that it is necessary to get a blueprint for making silica sand. This thing seems to be more and more useful in the future, and it feels like the key to the technological revolution!

Yu Qian'an remembers that sand is silicon dioxide, right? So high-purity sand should be easy to make silica sand, right? Why have I never seen this blueprint before?

Yu Qian'an asked Le Xing: "Have you seen anyone selling silica sand or silica sand manufacturing drawings in our area?"

Le Xing: "No? That thing is very useful to you?"

Yu Qian'an: "You ask. If I ask, everyone will ask a very high price, and they may be reluctant to sell it because they know it is useful."

Then Yu Qian'an asked Wang Yang: "Have you seen the drawings of silica sand?"

Wang Yang: "I haven't seen it, but big brother, I feel that this drawing should be very useful. Silica sand is extracted from silicon dioxide, which is sand, but it is indeed the cornerstone of modern technology. All computer intelligent automation control cannot be separated from wafers, and the best and most mature wafer manufacturing technology is silicon wafers, that is, single crystal silicon.

High-purity silica sand should be a prerequisite for manufacturing wafers."

Wang Yang doesn't need to help analyze this. Yu Qian'an made several things with wafers or some intelligent programs, which did not use silica sand, so silica sand is wafers, and not just wafers. I feel that this plastic plus gold, silver, and tin are used to make circuit boards.

Yu Qian'an: "Please keep an eye out for me. If anyone has this blueprint, please help me exchange it back! By the way, are you still in touch with Liu Jun?"

Wang Yang: "Of course, Liu Jun is very powerful now. There are more than 400 regions that have his organization branches, and he has tens of thousands of subordinates. He is really a big boss among big bosses. I feel that only you can compete with him!"

Yu Qian'an: "Don't flatter me. I want to compete with him. I will talk about it when I can be invulnerable to swords and guns and not be hurt by artillery!"

Wang Yang: "Boss, I heard that Liu Jun has trained several regional captains, and their physical fitness is three times that of normal people. They are very strong! Definitely super "Super warrior!"

Yu Qian'an: "Please ask Liu Jun for me if he has silica sand manufacturing drawings. Blue and green are fine. If he doesn't have white, it's fine."

Wang Yang: "Okay, boss, I understand! I'll ask now.

He must have it, but he has a staff department and no shortage of smart people. He must know the value of this thing. If you ask, he may not agree, right?"

Sure enough, Wang Yang is still very smart. Liu Jun has begun to cultivate his own manufacturing talents, and from the situation of several transactions, the local government either directly gives basic materials or gives drawings that are useless.

He must have a lot of good things in such a large organization, but he is unwilling to share them, which proves that he is still very wary of Yu Qian'an, so Yu Qian'an did not ask him directly, but through Wang Yang.

Although Wang Yang followed Yu Qian'an and helped Yu Qian'an sell things in the Goblin Camp, Yao Yong's large organization has been disbanded, and Liu Jun should not have thought that Yu Qian'an is still in contact with Wang Yang now.

Even if you know, it's okay. You won't lose money if you try. At most, you can get it yourself when you are lucky! I have a card of nothing, so why would I be afraid of not having luck?

After waiting for a long time, Wang Yang replied: "Boss, Liu Jun said there is a white one, but it needs a blue or higher seed to exchange, and I don't have it."

Yu Qian'an: "I'll give you a melon seed, you try to exchange it with him, if he asks, you got it from the melon I bought."

Wang Yang: "Okay!"

After a while, Wang Yang traded a white silica sand manufacturing drawing to Yu Qian'an.

Yu Qian'an took out the green upgrade scroll and upgraded it first!

Then look at the new requirements. This thing actually needs a separate carriage to accommodate it!

Making materials:

Steel (green) x200

Parts (green) x180

Silica sand (green) x1

Glass (green) x10

Copper (green) x2

Plastic (green) x1

Yu Qian'an thought about it and decided to make it first, and then use the blue upgrade scroll to upgrade it. This is not easier than upgrading the blueprint directly. What if the blueprint needs some rare materials when it is upgraded?

After it was made, Yu Qian'an placed the smelting furnace carriage behind the manufacturing center.

Yu Qian'an walked in and saw a smelting furnace, a centrifuge, and some machines that Yu Qian'an didn't recognize.

Fortunately, only coal (green) is needed to make silica sand, and sand also has a lot of electricity, consuming 50 kilowatts per hour. Even if Yu Qian'an wants to use it, he needs to turn off some electrical appliances.

If the glass of the whole car can be replaced with blue, then it can be used for power generation at will.

After solving the silica sand problem, Yu Qian'an continued to read private messages. A lot of people asked him to buy various things, but they took out some green materials or white blueprints. Some people even wanted to exchange white materials with him. This is not as good as those who sent all kinds of flirting photos to ask him for things!

At least those good-looking photos are saved, maybe they can be used in the future!

The legs are long and straight, and they look really good, but the stockings are too dirty, and I don’t know how long it has been since they were washed.

Yu Qian’an saved the picture and directly sent a 500ml cup of ordinary water. Brother, don’t look at it in vain, brother will give you water to drink!

Anyway, Yu Qian’an’s white water is useless except for taking a bath and washing vegetables, and there is too much to use up! You can’t change much, so it’s better to give it to those who can bring you happiness!
