The fantasy world and the science fiction world are completely different systems, and Ye Yun has a deep understanding of this. For example, if the science fiction world wants to cultivate steel, first of all, you want to build a steelmaking furnace before you can start making steel, but the fantasy world doesn’t need it. They can easily make the temperature of the flame reach a very terrifying level without using the steelmaking furnace. They don’t even need fire to extract steel directly from the ore. Now Ye Yun does this.

In the past three years, Ye Yun spent most of his time studying various herbs, ores, as well as various talismans and formations, except for practicing. Although most of them were reading books and there was no actual operation, he had accumulated a lot of knowledge for him, and it was not easy to refine an iron ore.

In fact, the reason why Ye Yun learned this knowledge was not only to pass the time, but also to prepare for his future path. After all, he was a person who had to travel through the heavens and all worlds. If he didn't have some wisdom, he might not recognize him even if he puts Baoshan in front of him. Therefore, in addition to practicing, he also planned to become an alchemist, weapon refiner, formation master, etc.

Ye Yun's idea was decided after he thought carefully. After all, he would not only stay in one world, and in the heavens and the worlds, each world has its own characteristics, that is, the things in each world have unique characteristics, and he can travel between the heavens and the worlds. If the spiritual medicines and immortal treasures of different worlds are mixed together to make pills, it will definitely have miraculous effects. If he wants to do this, he can only rely on himself, because he cannot keep an alchemist or weapon refiner with him all the time. If he handed over herbs, strange things and other things to alchemists or weapon refiners in other worlds, they may not be able to understand those things, so he can only rely on himself.

And the most important point is that practice is actually cultivating the mind and practicing Taoism, but what is Tao? Lao Tzu wrote in the "Tao Te Ching":

If things are mixed, they will be born in heaven and earth.

Silent and lonely, independent without change, and moving around without danger, can be the mother of the world.

I don’t know its name, so Qiang is called Tao, and Qiang calls it Da. Dag is called Da. Da is called Fa, Death is called far, and far is called Fight.

Therefore, the Tao is great, the sky is great, the earth is great, and people are also great. There are four elements in the domain, and people live in one of them.

Man follows the earth, the earth follows the sky, the sky follows the Tao, and the Tao follows nature.

What does this mean? The explanation Ye Yun saw is as follows:

There is something that is in one form that exists before the heaven and earth appear.

Silence, emptiness and invisibility. It exists independently without changing, and runs circulating without stopping. It can serve as the mother of all things in the world.

I don't know its name, so I barely call it "Tao", and then barely named it "Da". It is vast and boundless and flowing endlessly, stretching endlessly and stretching far away, stretching far away and returning to its original source.

Therefore, "Tao" is great, the sky is great, the earth is great, and man is also great. There are four great things in the realm of existence, and man is one of them.

What people learn from the Dharma is the earth, what the earth learns is the heaven, what the heaven learns is the "Tao", and what the "Tao" learns is the state of oneself.

In fact, the meaning of Lao Tzu's passage is what he believes in the evolution of the universe. In other words, "Tao" actually refers to the changes and laws of the world, and practicing Taoism is to master these laws.

However, is this related to Ye Yun's desire to be an alchemist? Of course, it is related. Alchemist, weapon refiner, etc. are essentially analyzing and mastering herbs and the characteristics of the refining materials have changed. These knowledge may just have the "Tao" he needs, and sometimes it can play an unexpected role. After all, Tao gives birth to one, one gives birth to two, two gives birth to three, and three gives birth to all things. All dharmas are the same. With more roads, there will always be a road that can reach the peak. As for time, he who can travel through the heavens and all realms is equivalent to an eternal existence beyond the world, so there is basically no problem of insufficient time.

Return to the topic.

Although the steel was refined, there were many impurities and the hardness was not enough. However, this was not difficult for Ye Yun. During this period, he had learned a lot of formations. He pinched his hands and rays of light flew out of his hands. He arranged them in a strange way over the pile of refined steel according to some strange rules, and soon formed a mysterious hexagonal formation. This was a formation specially used to extract impurities, but the level was not high, but this was enough for Ye Yun. After all, he was not used to create magic weapons, he just wanted to make some gadgets.

Ye Yun didn't know if there was storage equipment in this world, but he probably didn't, because he found that people in both novels and TV series were holding weapons. If there were storage equipment, it would definitely not be the case. Ye Yun also hated this, because if there were storage equipment, the things he had fiddled with would not be missing today and one tomorrow.

"It seems that the next world needs to find a world with storage equipment, otherwise everything must be placed on it, which will be too embarrassing for time travelers." As he thought, Ye Yun picked up a piece of steel as big as a fist (adult), used the formation to break it into small pieces, and then melted it into the shape he wanted.

More than an hour later, he assembled a thing that was 70% or 80% similar to the fan in this world. In fact, this thing is just a fan, but the fan of the current world (the real world, Ye Yun’s original world) uses electric power to drive the motor, and this magical fan is driven by spiritual power.

Ye Yun looked at the all-steel building. Apart from the lack of plugs and many mysterious patterns on it, other fans that are basically no different from the fans in the world, and nodded with satisfaction. The fan is simple, just one motor and a few capacitors. Now he uses the methods of the fantasy world to make it simpler. Even capacitors and motors are not needed. He just engraved a few magic arrays on the fan blades and bearing shafts, and then inscribed two or three mini spiritual gathering arrays on the base, and then put a magic array to control the transmission of spiritual energy on the knob.

After playing with the silver fan from his own hands, Ye Yun put him on the ground, then twisted the knob on the magic fan. As the knob turned, the silver metal blade of the fan turned, blowing Ye Yun and his long hair on his back.

Looking at this fan that combines science fiction and fantasy, Ye Yun's eyes were a little red, "I didn't expect that I have been in this world for three years without realizing it, and I don't know if you are in another world well."

After a little remembrance of the past, Ye Yun continued to do it. Today he not only wanted to get a fan, but he could also get a refrigerator higher, otherwise things would be easy to break in summer. And most importantly, he wanted to eat popsicles. He missed the time when he frozen mung bean ice.
