In a flash, night came, and there were basically no pedestrians on the streets. A dark shadow passed through the city at great speed, and quickly came to a stop near the library.

"Two people......" the shadow poked its head out of the shadows and whispered as he looked at the location of the library. At this moment, a car drove quickly on the street in the distance, and the light that swept almost instantly reflected the dark face. It was Li Xing, who was turned away from the library in the afternoon.

Li Xing retracted his breath, quickly rushed out of the corner with light work under his feet, came to the wall of the library like a gust of wind, pressed the wall with both hands, and climbed up from the wall like a lizard.

Came to the top of the wall, used his true qi to break the bolt of the window, and quickly dodged through the window into the library. Turning around and closing the window again, he began to check the environment in the library.

The layout is not different from other libraries in the world, the only difference may be the placement of bookshelves. Rows of solid wood bookshelves are connected end to end, one after the other in a notched circle, and the notch is where the door is located. In the straight line opposite the doorway, two rows of bookshelves separated by one meter are placed in the middle of the house.

After clarifying the layout of the house, Li Xing quickly walked to the bookshelf, took out a book from the bookshelf and read it......

The night passed in a flash in Li Xing's reading. When the morning sunlight filtered in through the window and shone on the book, Li Xing first shook it, then closed the book with both hands and put it back into the shelf. Then he turned and ran briskly back to the window, grabbed the top edge of the window frame with both hands, rolled over and jumped onto the roof, and then disappeared over the eaves in a few flashes.

A few days later......

"En......" early in the morning. Li Xing, who finished reading the book in his hand, stretched his waist greatly, and then put the book back on the shelf. Lay down on the spot.

"I see." Li Xing's mouth let out a faint sigh of emotion.

After reading for the past few days, Li Xing finally figured out the reason why his refining array would activate on its own without the energy to provide it. The reason is simple. Just because the world is different!

In this world, the circle outside the refining array is not just a symbol and summary of simple symbolic meaning, but also a body of energy. Because all the refining arrays in this world are based on the circle shape. There must be a central point in the circle, and the upward force that gathers from the circumference to the central point is the circulation of power, the power of consent.

And the name of this power is called the power of the circle. In addition, the circle also indicates the time cycle required during the refining process or operation.

The source of the energy is found, and the rest is understood. The alchemy process of this world is to draw the basic circle to ensure the existence of the power of the circle. Each alchemist's own unique alchemy symbol is then added to the circle, and even the same substance will be represented by a different symbol in the hands of two alchemists. In the end, it is to press your hands on the refining array to convey your thoughts and get the final desired result.

In other words, the symbol of adding a family in the middle of the alchemy of this world is more like a half-finished product. For example, the result you need is an item made of ice, and the symbol represents the process of water and cooling, and the alchemist's own mind shapes it to get the result.

But the alchemy symbols that Li Xing learned in the Harry Potter world directly describe the result. For example, if you need to turn charcoal into diamonds, the symbol represents the entire process of converting charcoal into diamonds.

"The alchemy of the world of Harry Potter is more inclined to manufacture, and the alchemy of this world is more inclined to application. Both have their own advantages and disadvantages, but I don't know if the alchemy of this world is common in other worlds, so I can ask the main god to help study it. Li Xing compared the alchemy of the two worlds in his heart, and finally thought.

Because the alchemy of this world is so convenient. Therefore, Li Xing hurriedly returned to the main god space and handed over the alchemy knowledge he had obtained to the deduction research center of the main god space for research.

However, to Li Xing's surprise, it was only two days. The results of the research have already come out, that is, in other worlds, it is not possible to cast the alchemy of this world just by drawing an alchemy array. Instead, it needs to consume other energy sources, because other worlds do not have the power of a circle that is unique to this world.

And this energy can be spiritual power. It can also be magic power, as for other powers, there is currently no substitute in the power system that Li Xing has contacted.

"Didn't you think you could use mental power? That way, I should be able to use it smoothly! "Originally, although Li Xing cultivated the Fruit Meditation Technique, because his efforts were far inferior to his cultivation of internal strength and the small universe, his spiritual power could only be said to be acceptable.

But after being strengthened and stimulated by the ability crystal, Li Xing's spiritual power has grown rapidly in less than a year, and it has even increased more than ten times compared to before he got the ability crystal, so there is no problem with supporting the consumption of alchemy, and if it is used with pure spiritual power, it is the least likely to be restricted by the rules of different worlds, that is to say, the alchemy of this world, Li Xing can also be successfully used in other worlds.

"Moreover, the consumption of mental power is still within an acceptable range." After trying to use his spiritual power to perform alchemy a few times, Li Xing carefully felt the changes in his spiritual power, and then refined several buildings in a row to confirm the consumption amount of different volumes, and finally came to a conclusion.

After doing this, Li Xing was overjoyed. Then the body instantly returned to the room of the main god space, and saw Saya and Shizuka Jukawa just drinking tea there, and in the exclamation of the two of them, they were carried back to the bedroom together, and began a harmonious and friendly movement.

After some hard work, Li Xing pillowed Shizuka's lower abdomen with one hand, and gently rubbed the softness on Saya's chest with the other hand and smiled.

"What are you so happy about?" Shizuka gently moved her body to make her body more comfortable, then bit her finger and asked a little naturally.

"Hehe, I've mastered a pretty practical power, of course I'm happy." Li Xing said with a smile.

"yes, that's great." Shizuka and Saya laughed as well.

"By the way, the two of you can also use this power, so why don't you learn it together." Li Xing said to Saya and Shizuka.

In fact, most of the women around Li Xing are learning martial arts, internal strength, small universe or mindfulness, which is similar to the route taken by Li Xing, and the other Nan Rika, Fox, and Kemira are learning gun fighting skills and ability enhancement, and only Saya and Shizuka are learning the magician system.

And to learn the alchemy of this world, Saya and Shizuka, who have a foundation in magic, have the most advantages, because not only are they good at spiritual power, but more importantly, they are easier to learn when learning alchemy knowledge. (To be continued.) )
