There are probably some transitions before the plot in those chapters, and then you can enter the plot. It just so happened that I also took the opportunity to make up for the animation...

====================

I found an empty and almost empty auditorium, avoided the few living people outside, and sat down in a corner against the wall. He raised his hand and took half of the stone pen back into his hand. After thinking for a moment, he began to draw on the ground. It was still the basic fire element array he drew in front of the library.

As the last stroke fell, almost immediately, the formation formation in front of Ito Cheng flashed a red light, and a green flame appeared in front of Ito Cheng.

Ito Cheng stared at the flames in front of him for a long time, then moved the stone pen in his hand again, and drew another basic formation diagram on his side. Similarly, after the last stroke was made, a blue light flashed on the basic formation diagram, and a ball of water appeared in front of Ito Cheng.

Ito Cheng's hand paused for a moment, and then continued to move, drawing the remaining two basic formation diagrams of earth and air one after another. Then I saw a yellow-brown light and a bright white light flashing one after another, and a ball of earth and a small whirlwind appeared in front of Ito Cheng.

"How could this happen?" Ito Cheng looked at the four substances in front of him and was puzzled. He waved his hand to erase the four formation formations in front of him and started drawing them again. It's just that this time the drawing is no longer the basic formation of the four elements, but the simplest metal conversion formation.

A moment later, when Ito Cheng wrote the last character, a blue and white electric light flashed on the formation. Then the land under the refining formation began to dent, and a ball of soil suddenly appeared in the refining formation, turning into a ball of metal and falling to the ground, making a "ding" sound.

"What's going on?" Ito Cheng felt a little scratched his head. It's not like these have never been drawn in the real world, but except for the four-element array that can be activated with spiritual power, other arrays require additional energy to be supplied before they can be activated. Why do we completely omit energy in this world and just operate it directly?

Ito Cheng, who still couldn't figure it out, threw the metal in front of him angrily. Then he stood up and walked out of the auditorium, wandering around the city.

It was night in a flash, and there were almost no pedestrians on the street. A black shadow passed through the city at an extremely fast speed and quickly came to a stop near the library.

"Two people..." The black shadow poked his head out of the darkness and looked at the location of the library and whispered. At this time, a car passed quickly on the street in the distance, and the light that swept almost instantly reflected the black figure's face. It was Ito Cheng who was turned away from the library in the afternoon.

Ito Cheng used [Zet] to seal his aura, and quickly rushed out of the corner with the special footwork of beating enemy Hakkas. He came to the wall of the library like a gust of wind, and pressed hard against the wall with both hands. It climbed up the wall like a lizard.

He reached the top of the wall, used the force of the earthquake to break the bolt of the window, and quickly dodged through the window and entered the library. He turned around and closed the window again, and then began to check the environment in the library.

The layout is no different from libraries in other worlds. The only difference may be the placement of the bookshelves. Rows of solid wood bookshelves are connected end to end, placed one after another to form a circular shape with a gap, and the position of the gap is exactly where the door is. On the straight line directly opposite the door, two rows of bookshelves one meter apart are placed in the middle of the house.

After knowing the layout of the house, Ito Cheng quickly came to the bookshelf, took out a book from the bookshelf and started reading...

----------------------------------------------------

One night passed in a blink of an eye while Ito Cheng was reading. When the early morning sunlight came through the window and shone on the book, Ito Cheng was stunned for a moment, then closed the book with both hands and put it back on the bookshelf. Then he turned around and ran quickly back to the window, grabbed the upper edge of the window frame with both hands, turned over and jumped to the roof, and then sat down cross-legged with a relaxed look on his face.

"Hahaha, this is a good location, just enough for me to study some problems." On the roof, Ito Cheng sat cross-legged and chuckled.

A few days later……

"Yeah~" In the early morning, Ito Cheng stretched greatly after reading the book in his hand, then put the book back on the bookshelf and lay down on the spot.

"So that's it." Ito Cheng let out a faint sigh of emotion.

After reading these days, Ito Cheng finally figured out why his formation array activated itself without energy. The reason is very simple, just because the world is different!

In this world, the circle outside the formation is not only a simple symbol and summary, but also an energy provider. Because all the formation formations in this world are based on the circular shape. The circle must have a center point, and the upward force concentrated from the circumference to the center point is the circulation of power = the power of agreement. And the name of this power is - the power of circles. In addition, the circle also represents the refining process or the time cycle required during operation.

Once the source of energy is found, the rest becomes clear. The alchemy process in this world is based on drawing a basic circle to ensure the existence of the power of the circle, and then adding each alchemist's own unique symbol inside the circle. Even if the same substance is used by two alchemists, The hands will also be represented by different symbols. The last step is to press your hands on the formation to convey your thoughts and get the final desired result.

In other words, the Tian family's symbol in the alchemy of this world is more like a semi-finished product. For example, the result you need is an item made of ice. The symbol represents the water and cooling process, and the alchemist's own thoughts shape the result.

But the symbols of alchemy in the main world directly describe the results. For example, if you need to turn carbon into diamond, the symbol represents the entire process of converting carbon into diamond.

"The alchemy of the main world is more inclined to manufacturing, and the alchemy of this world is more inclined to application. Both have their own advantages and disadvantages, but I don't know whether the alchemy of this world is universal in other worlds." Ito Cheng considered the two worlds in his mind. After comparing it with alchemy, I finally thought.

Then he sat up from the ground, entered the Rubik's Cube world, and appeared directly in a relatively desolate place in the Rubik's Cube world.

Ito Cheng drew the alchemy formation according to the newly learned alchemy technique, then pressed his hands on the ground, and an image flashed in his mind. A moment later, a cold wind blew by. The ground was still the same, and there was no change at all in the formation formation.

"Is it really because of the unique rules of that world?" Ito Cheng straightened up, looked at the formation formation on the ground, frowned and thought for a moment, then released his spiritual power outside his body and touched the formation formation on the ground. . Instantly, a silvery white light flashed on the ground, and a doll made of sand appeared in the center of the formation.

"You can actually use spiritual power to replace the power of circles!" Ito Cheng said in surprise. Then he drew a new formation, imagined a huge object in his mind, and then poured his spiritual power into it...

In an instant, Ito Cheng only felt that a small part of his mental power had been lost, and then a huge earth-yellow building like an Egyptian obelisk cup appeared in front of him.

"Fortunately, the consumption of spiritual power is still within the acceptable range." Ito Cheng carefully felt the changes in spiritual power, then refined several buildings in succession to confirm the consumption amount of different volumes, and murmured.

Then he withdrew his mental power and quickly converted the energy in his body. A stream of light red gas appeared in Ito Cheng's hand and transformed into a small refining formation.

Ito Cheng clasped his hands together and shouted, a blue and white electric current emerged from his hands and quickly flowed to his arms. Then he pressed his hand on the ground, and sharp spears protruded from the ground, pointing towards the void.

"Nian Qi can actually be constructed into a refining formation!" Ito Cheng exclaimed subconsciously.

After trying it several times and confirming that the mind energy could indeed construct the formation, Ito Cheng felt happy. Then the body instantly disappeared into the wasteland and appeared in the central house. Amid Yaye's exclamations, he picked up Yaye and ran back to the bedroom, and went to watch the wind and rain in Wushan with Yaye.

After the hard work, Ito Cheng put one hand behind his head and gently rubbed the softness on Aye's chest with the other, smiling.

"Why are you so happy?" Yaye moved his body slightly to make his body more comfortable, then looked at Ito Cheng and asked in confusion.

"Suddenly I have mastered a kind of power and feel that I have become stronger again. Of course I am happy." Ito Cheng said with a smile.

"Really, that's great." Yaye also laughed.

"By the way, you can also use this kind of power. Why don't you learn it together." Ito Cheng looked at Aye and said.

"Really? But if you study so much, will you not have enough energy?" Yaye screamed in surprise at first, and then asked with some worry.

"It doesn't matter, you just need to master one application method of this power, and it won't affect you in any way. And aren't you also practicing the technique for cultivating chakra? Don't you feel that your mental power has increased? ?" Ito Cheng first explained Yaye, and then asked with some confusion.

"Ah? I haven't noticed." Yaye said in surprise after hearing Ito Cheng's explanation.

"If you didn't pay attention, you didn't pay attention. Anyway, it won't affect your learning of new powers." Ito Cheng said.

After the two of them lay in bed for a while, they came to the main hall and stood facing each other.
