"It's best to carve some reinforced magic runes, as they're full of heavy ammunition. The little angel admonished.

"Understand, I'm going to design the drawings of the cart now, and as for the alchemy runes, it must be Aladdin's work. Emperor Shi Tian said with a smile.

"And what about the mission here?" asked the little angel.

"Generally speaking, how do the chiefs of the other grades pump water?" asked Emperor Shitian.

"The chiefs of other grades also depend on the situation, their own people will smoke a little less, those who have no friendship will smoke a little more, and those who have a grudge will not give it at all. The little angel said.

"If the task is not completed, will there be any damage to me?" asked Emperor Shitian.

"Of course there is damage, after all, you are the person in charge, how can you not do things after receiving so many benefits?" the little angel said: "You must complete at least 90% of these tasks, otherwise you will be punished by the academy." ”

"That's it!" Emperor Shi Tian immediately said: "Give the little rabbit two intermediate tasks with one as a hundred, my two sisters are also divided into two intermediate tasks, the advanced tasks are left to me myself, and the rest is announced, although those people are not good things, but they can't be forced too much, just draw thirty percent!

"Okay, in this way, you also have an income of more than 100,000 black iron coins!" said the little angel.

"Haha, I finally didn't become the chief for nothing!" After Emperor Shi Tian finished speaking, he flashed back to Valhalla and began to ponder the design of the four-wheeled cart.

As a grassroots emperor, Emperor Shi Tian is very down-to-earth, even when he was a child, he once pulled a big car, and later grew up, and learned a bunch of things related to science and technology, naturally he is no stranger to design work, he is now personally involved in the design of various types of main warships, just a big car, it is simply handy.

It didn't take long for Emperor Shi Tian to design the drawings according to his own needs, and then he personally ran back to his camp, gathered dozens of cave people and carpenters who were good at making carts, and personally assigned them to work.

Some went to the wheel, some to make the skeleton, and some to make the axle, and everybody got a copy of their own drawings.

After arranging for these people to work separately, Emperor Shi Tian went to the territory of Danmaku Ji again, found those craftsmen who were good at metalworking, and asked them to make a batch of ball bearings.

This is one of the most important parts of the car, with bearings and without bearings, there are two completely different varieties, and the load capacity can even differ several times.

A four-wheeled cart without bearings can be held up by a load of several hundred kilograms, and the connection between the axle and the wheel is prone to problems after not taking much time.

With the ball shaft, the same cart can load several tons of things, as long as there is enough lubricating oil in the bearing, then the cart can be used for a long time.

The alchemy machinery on the side of the barrage can even produce alchemy guns, which shows that its accuracy is still very high, enough to produce qualified ball bearings.

Under the instructions and guidance of Emperor Shakti, those clever craftsmen quickly manufactured the various parts of the ball bearing according to his requirements, and then successfully combined them into ball bearings.

Of course, if you think that's the end of it, you'd be naïve.

In fact, today's ball bearings are only semi-finished products, and if they are installed on the axle like this, they will definitely not take long to break, because there is one very important thing missing, which is lubricating oil.

In order to get this kind of thing, Emperor Shi Tian hurriedly came to the territory of Long Pao Ji after arranging the mass production of ball bearings.

As soon as I came here, there was a fishy smell in the air, and there was no way, who called this place a place to deal with prey.

Every day, thousands of catties of various animals are skinned, cramped, and then steamed and dried, and the smell can be fragrant.

Against the strange smell, Emperor Shi Tian found the person in charge here and asked them to take out the stored oil.

The oil here is actually a bio-oil made from animal fat, which looks very cute and can even be used directly for stir-frying, but it cannot be used on ball bearings.

The lubricating oil needed on the ball bearing is a very viscous oil, which is almost solid at room temperature, similar to edible butter.

Therefore, Emperor Shi Tian must also find a way to turn the current liquid oil into the viscous lubricant he needs.

Emperor Shi Tian vaguely remembered that this process required the use of alkali and salt, and he happened to have a salt mine here, which could produce table salt.

So his only trouble now is the strong alkali, as well as the specific reaction process and formula.

To tell the truth, Emperor Shi still has some experience in chemistry, at least there is no problem with this simple chemical reaction.

It's just that, after all, this is the divine realm, and there is an anti-scientific thing called magic, which is full of everything, and will always jump out of the cold and suddenly to subvert the scientific knowledge you have learned in the lower realm.

Therefore, Emperor Shi Tian did not dare to guarantee that his knowledge would be useful, so he could only explore it slowly.

In this way, Emperor Shi Tian led a group of people to start the arduous chemical refining work.

Five days later, the barrage Ji and others returned, and they came here to see Emperor Shi Tian as soon as possible.

At this time, Emperor Shi Tian, because of the long-term chemical refining work, had a smell of grease on his body, and his face was covered with black ash.

When everyone saw him, they were all shocked on the spot.

Barrage Ji hurriedly asked, "Brother, what are you doing here?"

"Refining lubricating oil!" As Emperor Shi Tian spoke, he pointed to a ball bearing that had been made next to him.

Seeing this, Danmaku Ji couldn't help but say, "Aren't we able to spend money to buy it? Why do we have to bother with this?"

Emperor Shi Tian had actually bought the bearings a long time ago, and his logging factory had them.

But the problem is that the thing is too expensive, and it is really distressing.

Moreover, Emperor Shi Tian planned to build a hundred four-wheeled cars, which would require 400 bearings, which was really not a small price.

In addition, he will definitely have more big cars and more bearings in the future, and if he wants to buy them all, it must be a sky-high price?

Emperor Shi Tian obviously preferred to toss a little now and achieve self-sufficiency.

So, in the face of the barrage Ji's inquiry, Emperor Shi Tian shrugged and said: "We will definitely have many, many big cars in the future, which means that we must produce bearings ourselves." And I can also take advantage of this opportunity to see if the chemical knowledge of the Nether can be used in the Divine Realm. ”

"And what did you come to the conclusion?" asked Danmakuhime.

"Under normal circumstances, it can be used~" Emperor Shi Tian then said angrily: "However, as long as the broken things related to magic power are mixed in, then, our chemical system will completely collapse, and it will be useless at all!"

"What do you mean?" asked the barrage puzzled.

"It means that things that don't have magic power carry out chemical reactions, which are completely in line with the laws of our nether realm. Emperor Shi Tian said helplessly: "However, if there is magic in the things involved in the reaction, such as these damn animal fats, there are some magic beasts in them, which contain magic power, and then carry out chemical reactions, all kinds of strange things will happen." ”

"What's going on?" asked the barrage curiously.

"The saponification reaction of soap should be produced, and sometimes the things that come out are as hard as steel plates, and they are not soap at all; but sometimes they simply become a pot of smelly asphalt; and the most disgusting thing is that the asphalt is extremely unstable, and every now and then it will explode, uncle, how many experiments have been done in the past few days, and seven or eight people have been killed." Emperor Shi Tian couldn't help but smile bitterly: "I never dreamed that my talent in chemistry was to make explosives!"

"Hahaha~" A group of people couldn't help but laugh.

After they finished laughing, Emperor Shi Tian continued: "But fortunately, my foundation level is solid, coupled with wisdom like the sea, it is not difficult at all, in just three days, I have made qualified lubricating oil, and now I am directing them to produce it in large quantities." ”

"So what are you doing now?" asked Danmaku curiously.

"Of course it's making explosives!" Emperor Shi Tian said excitedly: "How can you have a gun without a cannon?"

"That's right, cannons are king!" "Danmaku Ji immediately asked excitedly, "Then did you make explosives?"

"No~" Emperor Shi Tian smiled bitterly and said: "I really can't grasp the change of magic power, obviously it is the same batch of oil, the same refining method, but the results can be completely different, the first time it is something that kills people, and the second time it becomes a perfume, it smells invigorating, and it is obviously a mutated stimulant." What's this all about?"

"Professional things should be done by professional people!" Barrage Ji then asked Aladdin behind him: "Do you have a way to make some alchemy products that can produce violent explosions, preferably solid." ”

"I do have some recipes for explosive alchemy, but the conditions here are too rudimentary, and many materials cannot be found, so it is impossible to produce them in large quantities. Aladdin said, "Actually, if you want to make alchemy cannonballs, the easiest way is to burst the circle with arcane dust. ”

"What do you say?" asked the barrage in a hurry.

"Arcane dust is the primary crystallization product of mana, we have magic water, it is easy to produce arcane dust, each gram of arcane dust contains a hundred points of magic power, and the magic power contained in ten grams of arcane dust is a full thousand points, which can activate a bronze-level burst magic array. Aladdin said: "For others, the intricate and precise lines of the bursting magic array are a difficult hurdle, and they must be a bronze-level alchemist to depict them, and it will take a month to do it, so this thing cannot be mass-produced." ”

"But for you, it's the easiest problem to solve. Aladdin said, "Your miniature robots that can accurately depict magic arrays can make a complex burst magic array in a matter of hours, making it possible to mass-produce alchemical cannonballs." ”
