Chen Yu said this for a reason, in his opinion, after all, the organ division is the organ division, even if it is a combat mechanism division, it is only to say that they are good at combat organs, not that they are good at fighting.

Even if the Mechanic reaches a certain level, such as a high-level Mechanic, he can control two or three "expert-level" combat trap beasts, or certain types of combat traps, it can also pose a huge threat to the Mechanic.

But it must be made clear that it is not the Mechanic itself that can pose a threat, and that the Combat Mechanism he controls - and this is quite important - the Mechanic can kill the Mechanic without having to fight the Combat Mechanism.

And to put it bluntly, this matter is a grudge between him and the Zhang family, and he has nothing to do with Sun Li. This revenge is not a gentleman, but Chen Yu definitely does not want to rely on the strength of others to take revenge.

Hearing this result, Sun Li also closed his eyes and sighed, he had already guessed this result, since the other party was just coming at Zhang Er, not him, it proved that the other party was very jealous of him, and he didn't want to directly conflict with him at this time.

However, even so, Sun Li had no intention of stopping there.

Seeing Sun Li's expression, Chen Yu's heart was also extremely warm, this is the teacher.

And immediately, Chen Yu set his eyes on Sun Li's chest, where there was a brass medal, at this time Chen Yu was naturally not the guy who didn't know anything, he knew what it meant, and a smile appeared on the corner of his mouth: "Congratulations to the teacher, you have been successfully promoted to senior organ division." ”

After three days, Chen Yu was able to get out of bed and walk, which surprised Sun Li, and at this time, Lu Kang also came to visit once, and Chen Yu also met the president of the Intermediate Organ Division Association for the first time.

After sending Lu Kang away, Chen Yu did not rest in bed as Sun Li said, but ran to the studio, he now urgently needed one or two combat mechanisms that could defend himself, and it happened to be a good way to try to apply the core of the mechanism.

Sun Li just sat on the side and guided.

When Chen Yu was lying on the bed, he had already finished it, so this time he started directly.

"You should still recuperate now, and if the intensity of your mind can't keep up, don't force it. Sun Li asked.

Chen Yu nodded, although it was said that the situation of the mind had little to do with the condition of the body, but after all, the two were unified within the same biological entity, and it was absolutely impossible to say that there was no influence at all.

Chen Yu closed his eyes and began to enliven his long-dormant thoughts.

However, when he tried this, his heart was suddenly happy, he obviously felt that his mind had become stronger, Chen Yu couldn't wait to release his mind, and sure enough, the mist mind became more viscous.

"Oh, have you broken through the fourth level?" Sun Li naturally discovered the change in Chen Yu's thoughts.

Chen Yu's face was happy: "Yes," but then he also showed doubts, this time he was only seriously injured, and he didn't use his mind at all during the battle, how could his mind grow inexplicably?

"You're not getting nothing this time. Sun Li said with a smile.

Chen Yu also smiled, he didn't dwell on how the strength of his mind could suddenly break through, but took out a square wooden board about fifty centimeters long and began to make a folding structure.

Regarding the matter of the core of the organ, Chen Yu naturally would not be stupid enough to tell Sun Li, even if Sun Li was his teacher, Chen Yu himself knew too well the value of "The Devil's Axe", and any organ master would not be able to maintain enough sanity when he saw it.

However, regarding the use of the core of the mechanism, Chen Yu did not hide it, he directly explained that he wanted to use a main control core mechanism device and the rest of the epitaxial combination into one, so as to make the size of the mechanism smaller and safer at the same time.

In fact, this is the essence of the core of the organ, but only this essence of the idea cannot achieve anything great. Chen Yu had gone through the ancient books in Sun Li's library, and he knew that as early as the Middle Ages, when the genre was swarming, someone had put forward this idea, but no one seemed to have succeeded in it for thousands of years.

After hearing this, Sun Li also praised this idea as really good, but it is not easy to systematize and put it into practice, and he even encouraged Chen Yu to take it as a major research direction, because once this idea is successful, it will definitely open up a new field in the academic world, so as to become the existence of the bull's ear.

Sun Li's words made Chen Yu faintly excited, but he immediately knew that with his strength, even if he held a treasure house like "The Ghost Axe", I am afraid that he would not be able to completely eat the core of the organ.

Step by step, Chen Yu began to make the core of a mechanism he named the "Rainstorm Shuttle Box".

Chen Yu did not have the slightest ability to hide his strength, and his own understanding of the core of the organ could not be regarded as a deep dialysis, and for a senior organ master, although it was a "novelty", it was definitely not up to the level of "cleverness".

With Chen Yu's current strength as a low-level organ master, if he could make Sun Li, a high-level organ master and a senior organ master known as the most outstanding in Qinghu City, feel "smart", it would be too nonsense.

In fact, although Sun Li has never watched "The Devil's Axe", he was able to make a point in many places when Chen Yu was making it.

After Sun Li's pointing, some of the original hazy places suddenly opened up, and his grasp of the core of the organ couldn't help but be more profound, and sometimes because it was not exactly the same as his original conjecture, there were a lot of conflicts, but there were more questions.

And these questions are also of great interest to Sun Li, although it is not very difficult, but the angle is very tricky, often giving Sun Li some new inspiration.

He became more and more happy in his heart, not only because he had received new inspiration, but more importantly, because Zhang Er, an apprentice, was so smart, it was too polite to say anything about inferences. One of his points often leads to several questions related to it.

While Sun Li was lamenting that Zhang Er was really talented and intelligent, and his children could be taught, Chen Yu also sighed that the knowledge and strength of the senior organ master were really not given in vain, he seemed to be extremely struggling, and the content that needed to be studied carefully was just a matter of thinking about it when he lowered his head.

The consequence of such a master-apprentice promoting each other and improving together was that Chen Yu succeeded in making the first core of the mechanism after replacing the three planks.

After making the core of the mechanism, the extension of the rest of the mechanism became extremely easy, and in just two hours, a small wooden box the size of a palm appeared on Chen Yu's table.

"Storm shuttle box!"
