After Chen Yu left the mysterious hut, he immediately went to a hidden place outside its "battle" range and began to set up a tent. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 Although it was not dark yet, he didn't have the heart to continue hunting orcs, because there was something more important for him to do, and that was to study the "recipe for making magic crystals".

When he got the first formula, Chen Yu discovered an amazing secret, so what changes will this second one bring to him?

After setting up the tent, he couldn't wait to look at the recipe.

"The Recipe for the Making of the Magic Crystal" is a finger-thick book, with the name of the formula written on the ordinary blue cover, but other than that, there is nothing, no patterns, no metal decorations, it looks like those pirated books, the quality is rough, and the beauty of the skill book is completely incomparable, which also explains the reason why it is not taken seriously - the appearance is too bad! In this era when everything is on par with appearance, ugliness is the biggest mistake!

Time flew by, and soon the next day came.

"Whew!" Chen Yu exhaled lightly with a complicated expression, slowly closed the book, it took him half a day to finally understand the recipe, and understand the production method and use of the "magic crystal".

Magic crystal,It is a kind of supplementary magic power that will only be used by the caster above the intermediate level.,That is, a prop of mana.,It's like a battery.,When the magic inside is used up,It's still able to be filled up again.,Very aspect,It's one of the indispensable props for the caster.。

As for its production method, it is very complicated and complicated, using many technologies that Chen Yu can't understand, such as two-dimensional cover technology, etc., which is difficult to understand. It's hard to even understand, and it's hard to replicate it in reality!

However, this is definitely not the reason for his complicated face.

His face was complicated because he needed a basic ingredient to make the Magic Crystal, silicon! This is not ordinary silicon, but silicon with 100% purity!

With current science and technology, it is impossible to produce silicon with a purity of 100 percent, at most 99.999 percent...... Nine, although this purity of silicon has been infinitely close to pure silicon, but it is not just not, it is not a slight, you know, 100% purity silicon and 99% silicon are completely two substances, and it is impossible to be replaced!

Without the basic material high-purity silicon, everything in the future will be in the mirror, and you can only see it, not touch it.

"This may be the difference between the real world and the magical world!" Chen Yu sighed, some things are easy to make with magic, but they can't be made with science and technology, and vice versa, this is not a question of who is higher or lower in technology in the two worlds, but because the technology trees in the two worlds are not exactly the same, they are like two branches on a big tree, that is, they intersect and diverge from each other - such as madness potions, Chen Yu can be made in the real world and in the virtual, but the magic crystal is obviously not good.

This is the reason why Chen Yu's expression is complicated, although this point, he has expected it for a long time, but he didn't expect it to come so quickly - he has just uncovered the mysterious corner of this world and encountered this situation, what if he gets the formula of the medicine that can cure him in the future, but he can't make it in reality?

He shook his head and refused to continue thinking, decisively exiting the game and returning to reality.

Regardless of his exhaustion, he got up and turned on the computer, and quickly typed on the keyboard, and in an instant, the "click" sound became one. He was so anxious that he wanted to take advantage of the memory of the "recipe for making magic crystals" to record it on the computer before forgetting it.

Although it is impossible to make a magic crystal in reality, some of the above ideas can be used in reality, such as the two-dimensional cover technology, which is used to store and compress the volume of ions. If, can be studied thoroughly, then, the whole world energy storage industry will take a fundamental leap, of course, the difficulty is very large, the key is that the study of this technology needs a lot of money, Chen Yu does not have so much money.

"Whew! Fortunately, I'm still the top student back then, and I don't remember it at all! Chen Yu spent an hour recording all the things he remembered in the computer, and selected some technologies that can be studied at the moment and made them into relevant research plans.

"I said, as an Internet addicted teenager, you are quite skilled in narcissism, why didn't you find out before? It's so well disguised, it's really a hypocritical person! A cold voice sounded behind Chen Yu.

Chen Yu shook his head helplessly, who else could be such a mysterious person besides Shu Rui? That is, if you are used to it, if you were a stranger, you would have been scared to death?

He stood up and stretched, yawned and looked at Shu Rui leaning against the wall and said, "Have you eaten in the morning?" Would you like to make you one? ”

Although it is already early autumn, Shu Rui is still wearing a cool today, with a wide T-shirt on the upper body and denim shorts on the bottom, and two clean long legs overlapped together, which is very eye-catching.

"Would you like me to eat 'instant noodles for Internet addicts'? Forget it, that kind of thing will break your life if you eat it! Shu Rui refused without hesitation, and then walked outside with long legs, saying as he walked: "Remember to close the bedroom door tightly in the future!" ”

So you know this is my bedroom! Chen Yu complained and walked towards the kitchen, as soon as he approached the kitchen, he smelled a familiar smell, and a bad feeling suddenly came to his heart.

"This taste...... If I'm not mistaken...... It should be ......" The more Chen Yu thought about it, the darker his face became, and when he opened the casserole, he saw that it was the "weird chicken soup" made by Shu Rui, a cooking idiot, compared to what he did last time, Shu Rui added a lot of new "ingredients", including cabbage heart, carrots, lettuce, not to mention, a pot of chicken soup is colorful and quite good-looking, it can be seen that Shu Rui is still very careful when making soup, at least it looks beautiful, as for the taste!

"Well, the taste...... Not bad, vomit ......! ”

Chen Yu walked out of his room with a pale face and walked towards another room in the small courtyard. There are two two-story buildings in this small courtyard, one belongs to Chen Yu, and the other belongs to Shu Rui and Nan Xiaowan.

"Hey! I'm in! Chen Yu stood at the door and shouted into the house.

As soon as he finished speaking, there was a rush and the sound of things breaking through the door, which did not stop until half an hour later. He is not surprised by this, it is basically the same every time he comes, unless Shu Rui is not at home.
