After Sun Wukong came back, he learned that the people of Baozi Mountain had already gone to their respective places, so he decided to continue his practice. Only with a plan can we grow. In addition to the physical practice accidents necessary every day, Sun Wukong also had to learn a lot of knowledge. In the previous life, Sun Wukong looked at geology and gunpowder the most.

Why does Sun Wukong want to look at geology? Because, no matter which life, in fact, its geological form is basically the same, if you can study this thoroughly, you can easily find many useful things, such as the metals needed: iron, copper, gold, silver, etc., the need for stone, including feldspar, fluorite, cryolite, jadeite, etc., as well as the required elements, such as coal, miscanthus and so on. So it's important. Gunpowder is even more important, and it is the most powerful in the period when it is not capable of fighting on its own. In the previous life, Usopp's ability was prominent enough, and if the gunpowder was developed to the top, it would be extremely powerful.

In this life, Sun Wukong looked more at agriculture and economic types, but he found that the agriculture and economy in this period were very different from those in the past, and it was difficult to use them in a timely manner, so many of the things that needed to be learned were completely invalid in Sun Wukong's view, because they could not be used at all in the future world, but they were more valuable than primitive methods.

After this, Sun Wukong began to develop gunpowder, that is, ammunition, in order not to be unfamiliar with the gunpowder of the past.

Ordinary guns used with bullets are certainly impossible. The production of ordinary bullets is complicated. But if there is a mechanized process, it will be very easy to make a bullet.

All the ammunition developed by Sun Wukong is a form. That is, a 1.5 mm thick shell is wrapped on the outside, and different types of ammunition are on the inside. There are five types of ammunition.

The first type, gray, is slightly larger than a tennis ball and does not weigh much, and belongs to the smoke grenade type, which will explode immediately when it hits an object, producing a huge gray smoke screen. Smoke screens are harmless to humans and do not produce blast waves or burns, but they can cause coughing and lack of oxygen, so gas masks may be required. The range of the smoke screen is generally about 300 square meters.

The second type is yellow, which is as large as a pinball in size and average in weight, and belongs to the high-explosive shell type. , and when it hits an object, it will explode. The power of the explosion is about 1.5 square meters, which will produce a powerful shock wave and high temperature burns, and the lethality of the shock wave is significantly greater than the power of burning and explosion.

The third is red, the size is slightly smaller than the pinball, the weight is average, it belongs to the type of incendiary bomb, after hitting it, as long as it hits the object, it will produce a huge flame, the temperature of the flame is extremely high, the instantaneous temperature is about 1300 °C, the range is about 70 square meters, the burning time is about 3 seconds, and the combustion of other objects is not counted. The red incendiary bomb is mainly a burning damage, and it is a great threat to wooden buildings and the human body of wooden armor and cloth armor.

The fourth is purple, the size is larger than the yellow high-explosive bomb, not completely round, more like a miniature football, belongs to the split high-explosive bomb, after hitting out, can not immediately hit the object, but fly for 2-3 seconds, after that, it will produce ten small explosive bombs split in the air, ten small explosive bombs, small individuals, less powerful than yellow explosive bombs, but wider range. If there is no collision in the middle and the successful splitting will cause unequal damage within a range of 500 square meters, mainly explosions, each small explosive bomb does not produce a high-intensity shock wave like the yellow ammunition, but will produce a high-intensity explosion, producing flames, the range of flames is about 15 square meters, the damage caused is mainly explosions and burns, but the value of injuring the enemy is higher.

The last fifth type is Usopp's black bomb, which is as big as a pinball, dark and translucent, and has uranium inside to produce a nuclear explosion, which is a nuclear explosion bomb with a super-earth amount. The weight is large, the flight range is long, and as long as there is a collision on the way, an explosion will occur, and the range of the explosion is up to 150 square meters, and the shock wave generated is wider, but the main thing is high-explosive, burns. The resulting high temperature exceeds 2000 degrees. It is the strongest explosive bomb and is very dangerous, and if used incorrectly, it can cause damage to both yourself and allies.

The five kinds of ammunition were researched by Sun Wukong according to his memory. The method of firing is basically a slingshot. Sun Wukong has gone through a phase of experiments, all passed, all the ammunition to make one, the time required is not very long, as long as you can find resources, there is enough manpower, you can form a powerful ammunition army.

Kiki doesn't understand what Sun Wukong is doing, and he never pays attention to Sun Wukong, he cares more about his son Sun Wuhan, and is more concerned about whether this family is rich and whether they can live a good life.

Recently, life has begun to be tense again, so Sun Wukong is also thinking about a long-term solution. But no matter how he thought about it, Wukong couldn't think of a way to make money. The main reason is that Baozi Mountain is extremely remote, there are no cities within thousands of miles, and you may find a few small villages in the surrounding places, but there are not many such places at all. So after thinking about it for a long time, Goku decided to ask Shenlong.

In the former world, Feng Mantian had read a fairy tale book, which should be called Aesop's Fables to be exact. This is a book for teenagers or children, and the philosophy in it is very deep. In it, there is a story about a beggar who wanted to become rich, and God saw that he was so pitiful, so he gave him a wallet from which he could take money, and take out one and another, that is, he would never be able to take it all. God told him that when you get the amount you want, throw this wallet into the river, but he didn't, he was so greedy, he started to take out the money from the time he got that wallet, and he kept it until he starved to death. Such people are not only greedy, but also very stupid.

But the person who wrote this story was very smart, and Sun Wukong thought that if he had such a wallet, he could take out a thousand yuan of coins every time he took out, and then he could never finish it. In this way, you will never have to worry about money again.

Thinking of this, Sun Wukong immediately took action and embarked on a journey to find the Dragon Ball. A few days later, Sun Wukong successfully fulfilled his wish and had this magical wallet. But Wukong didn't tell Kiki about this, because he was afraid that Kiki would become the greedy person and play with his wallet twenty-four hours a day, so he hid that wallet.

Anyway, why don't you bring it with you, Sun Wukong also thinks, but if Qiqi finds out that she has private money, I'm afraid she will be screwed in her ears.
