Although the development of the potion did not meet the expected kind, Zheng Yichen was also very satisfied with the better product. This potion can quickly occupy the market. Zheng Yichen had no time to do this for sale, but he had a very good partner.

It was just because of the potion that Zheng Yichen had less time every day. Yilin looked for him from time to time, not asking for Zheng Yichen's blood, but his magic. She discovered that because Zheng Yichen's magic has assimilation characteristics, it can produce some wonderful effects in many aspects. This magic can play a role similar to a binder!

The production of magic potions requires the introduction of some magic power to affect the material and make the material work, but some of those materials are not compatible, which requires testing the user's skills. Zheng Yichen's magic power may minimize the incompatibility of this material.

But the only trouble is the uniqueness of his magic power. Yilin used many methods but failed to remove the part of the magic power that belonged to Zheng Yichen's power.

"Are these the powers you collect?" Zheng Yichen looked at some containers in front of him with curiosity. Each container carried a ball of unrestrained energy, with completely different colors. At the same time, these forces also exuded their own unique aura.

Zheng Yichen even felt the breath of power that he had experienced when he passed by.

"Well, different forces can get extra gains when researching them. This type of power has given me additional information in ice-type magic. Even if I don't have this type of power, after researching and modifying the magic array pattern, it can be more than 90% close to the ice-type magic effect released with this power." Yilin said, looking at a ball of ice-white special energy.

This ball of energy exudes the aura that appeared in the snow-capped mountains when Zheng Yichen felt that will.

"What about my strength?"

"If you ignore the special effects attached to your ability, it is ordinary magic." Yilin said lightly, tied up the magic power belonging to Zheng Yichen into a blank container: "My research is just like this for the time being. If you want to leave, you can leave at any time."

It’s not that Yilin doesn’t want to further research, but that there is really nothing to study at the moment. She has already understood Zheng Yichen’s abilities and has collected a lot of magic that has been affected by Zheng Yichen’s abilities. The subsequent research is just based on those magics. As for Zheng Yichen himself... unless he performs some practical behaviors, he really can’t study anything next.

"That's it." Nodded. Apart from this research, Zheng Yichen was really reluctant to give up on this place. Not to mention the collections in Yilin's library, the magic research notes alone benefited Zheng Yichen a lot. At least when he released some magic, it would not be the most primitive version.

The problem of making high-level demon soldiers that had troubled Zheng Yichen before has disappeared now... As long as you leave here and make time, you can make it immediately.

"If you want to read a book, you can leave a backup projector here." Yilin said.

Zheng Yichen glanced at Yilin in a little surprised. Is this considered to be a retention?

"Some of your ideas are very novel, so when you are fine, I want to listen more." Yilin said without any concealment. Zheng Yichen is not as knowledgeable as her in the other world, but the things on earth are another matter. When Yilin goes to Zheng Yichen's place for no reason, she often hears him muttering some information as he looks at some of his notes.

And she muttered with words that she couldn't understand, and those notes... Except for some translated versions, most of them were quite strange square characters. She tried to record some square characters, and then looked up some of her own notes, but she did not find any relevant information records. This kind of text has always appeared!

It may be a unique text created by Zheng Yichen... But is this possible? If it is a few dozen words, it would be fine. The number of those words is too large, and even if she can't understand it, she can see that such words must have a period of development. It is not certain how long it will take, but it is definitely older than Zheng Yichen.

This is definitely not a text created by Zheng Yichen, but she couldn't find the source at all. She wanted to ask Zheng Yichen for advice without shame. However, Zheng Yichen, who was generous in other aspects, was extremely conservative in this regard. Even if she took out a kind of exchange that made Zheng Yichen extremely excited, in order to exchange for the source of this text and learn from them.

If she had to learn other words, she could learn without even exchanging them, but those... were meaningless. She had already mastered everything she could master. And such words that could not find any source information, and even had no clues. Yilin felt that it was worth it to make such an exchange...

But the problem is that the parties are unwilling to do so.

"Also, don't you really think about that kind of text?"

"Writing, forget it. I don't want them to spread too much." Zheng Yichen thought about it, but he still refused. Although there were Chinese characters, even if Zheng Yichen took the initiative to teach, there were not many people willing to learn this foreign language, but he didn't want to do this. Those people do not care whether they learn or not. If they want to learn Zheng Yichen, they are unwilling to teach. It would be great to have Chinese by themselves.

It doesn’t take any effort to record anything and think about why others will not discover the information. In this way, why leak it out?

"We can sign a contract. Without your authorization, I will not leak any information in this kind of text to others?" Yilin asked after thinking about it. She didn't have many other shortcomings, and her only shortcomings are...the desire to study is strong!

Zheng Yichen's words are more concise than the general texts in mainland China. Even though she has not read Zheng Yichen's complete Chinese notes, she has read the translation. The number of pages in the translation is about one-third more than that in Chinese. As for the impact of signing the contract, Yilin didn't care much at all. After she mastered this kind of text, she had no idea of ​​revealing it. She still said that she spent some money to exchange for things, so why should others know?

And the niche text, the more confidential it is. If it is a text that only a few people in the whole world know, that would be even better. You should know something that must be kept confidential. If you really encounter someone who is interested and finds a way to get it, it may not be possible to keep it confidential. However, if you make such text that is difficult to find the source, the intensity of confidentiality can naturally be greatly increased.

"..." Zheng Yichen looked at Yilin who was waiting for her reply. The other party even brought out the contract. Zheng Yichen felt that if she refused, she would probably not mention Chinese things in the future. The dignity of the witch... Tsk, it is obviously stronger than that of ordinary people, otherwise how could they be particularly proud in their own fields?

Refusal is not a matter. Zheng Yichen is considering the possible impact of this incident. Yilin is very capable. If she can, Zheng Yichen also wants to establish a good relationship with her. With such a good relationship as the foundation, it is easy to sit down in the future. For example, the relationship with Qin and the once good cooperation allows Zheng Yichen to cooperate with everything in hand.

"Let me see how the contract first?"

"Okay." Yilin nodded and took out a piece of vellum paper from an unknown creature from a drawer. Instead of using Dan Marina's fingers to modify the contract text, she took out a pen and wrote it on it. Looking at the pen, Zheng Yichen scratched his cheek slightly. How could she say that this pen was also replaced by Yilin from herself.

Yilin is very passionate about exchange... or it is her habit. If she wants to get anything, she will not take it in vain, but will pay what she thinks is equal. Zheng Yichen said that this is very good. He doesn't like to take other people's things for nothing. During this period, Zheng Yichen cooperated with Yilin's research and exchanged many small inventions he made. Those things are very suitable for daily use, but a considerable part of them was blocked by Zheng Yichen.

Holding this contract, Zheng Yichen glanced at the contents on it. There was nothing missing. It was a very rigorous contract. He felt the power of the contract carefully, and couldn't help but twitch: "Why do you like this evil contract..."

"Because the power of this contract is the most binding." Yilin said lightly: "How?"

"No problem, just do it." Zheng Yichen nodded and agreed to this contract. The signed contract turned into black ashes gradually dissipated in the air. Yilin took out a dark blue crystal. This dark blue crystal was the one she took out when she made the magic barrier before.

It is just because the power is lost too much, the color has lost its original depth. Even so, the crystal still contains extremely powerful magic power. This is not only a super magic crystal, but also many magical effects. For example, the magic power inside can be absorbed, similar to ice crystals and fire crystals. After absorption, it can affect its own magic attributes. When it releases magic, it will get an additional increase.

This dark blue crystal is also that kind of thing. The difference is that its improvement will not change the nature of the individual's magic power, but will only improve the quality! Although the quality of magic power can be gradually improved through personal cultivation, using this magic power crystal can avoid a long time of cultivation... Of course, it will not increase the amount of magic power.

The amount of magic is not important. Anyway, Zheng Yichen does not lack magic power. What he lacks is the magic quality improved by long-term cultivation. Because of the assimilation of magic power, the magic quality in the magic weapon summoning book is the same as Zheng Yichen himself. Zheng Yichen's magic quality has been improved. As long as some of the improved magic power is introduced into the magic weapon summoning book, this magic power can quickly transform the huge magic power accumulated in the whole book, so that it can reach a level of magic quality as itself.

This crystal was of great help to Zheng Yichen.

After absorbing the special magic power inside, this crystal also has a certain purpose. It has excellent energy bearing properties and can be regarded as a battery in normal times, but Zheng Yichen does not lack a battery... He just lacks such a special material as the main part of a prop. What is it? Of course it is the core of power that I had imagined before!

He originally went to find something that could bear enough, and made it specifically to store other types of energy he grabbed, and left it directly in his body, pointing out some attention at every moment. Otherwise, if he was not careful, the power would be completely assimilated by his own magic power, which would be troublesome.

Putting this crystal in his mouth, Zheng Yichen mobilized his magic power to absorb the magic power in the dark blue crystal, because it was absorption, just like the accumulation of magic power on normal basis, and the magic power in the crystal was not harmful, so it did not trigger the assimilation effect, which was a normal cultivation accumulation. Unlike usual, the absorbed magic power quickly changed the quality of Zheng Yichen's own magic power, and the quality of his magic power was increased at a normal speed of dozens of times. This process will last for a long time.

"Well... Okay, I'll teach you Chinese..." Zheng Yichen split a projection and was about to start calling Yilin to recognize words, but she shook her head slightly.

"It's too inefficient here, a different way."

Her feet were lifted off the ground and flew to Zheng Yichen's head, and reached out and gently pressed it on his forehead: "Don't resist me too much..."

With seven words, Zheng Yichen sounded the first sound very normal, but Yilin's voice fluctuated a little when she was the second word. When she was the last word, it simply turned into a blurred long sound, and his eyes were blurred together. He suddenly woke up and came to his senses. What Zheng Yichen saw was the bedroom in his dream space.

"Single style." As he said something similar to when Lolith entered his dream space, Yilin observed around, and her eyes couldn't help but stagnate on the computer that was on, and she frowned slightly: "I regret it a little."

"Huh? What do you regret?" Zheng Yichen asked in confusion.

"Nothing." She shook her head. Zheng Yichen's dream space was incredibly stable. She felt the aura similar to the magic barrier produced by the pseudo-world barrier. In such a stable dream space, it was easy to control the "invader" entering here. And the more stable the dream space, the higher the control of the dream owner here. Zheng Yichen's dream space... has a guaranteed control of more than 90%. This is the guaranteed guaranteed after the invader's strength is strong enough and the competition will not be lower.

However, his dream space is a bit small. When he opened the bedroom door and looked out, he could see the living room. However, when he looked out the window, it was endless and deep, and it seemed like he was going to be swallowed up. There was an absolute forbidden area for existence outside the dream owner. This is also an abnormal place. The edge of normal dreams will blur, but the range will definitely not be too small.
