When exchanging secret techniques with Yun Wangyuan, Chenping found that this guy was simply a genius academically, and he only briefly introduced his own reverse vortex secret technique, and he was able to draw inferences. Not only did he learn Chenping's secret technique in a moment, but he also saw that Chenping had made several mistakes when using the secret technique, and helped Chenping correct them one by one. On the contrary, when Chenping was learning the technology of making star pattern cards, he was scolded by this guy so much that he had to record the entire manufacturing process with smart glasses and go back to practice slowly.

In fact, Chenping's learning speed is not slow when he enters a state of thoughtlessness, but Yun Wangyuan's intelligence is really perverted, and Chenping can't be compared with it at all. However, after this exchange, Chenping found that this guy knew a lot of things, but he didn't have any ideas. As long as he knows and has time, he is willing to teach to his students. It's just that now there is only one student who can get along with him, so Chenping is not only an experiment, but he can occasionally learn something special from this teacher.

"Teacher, what level of star pattern are you?" After the experiment was completed one day, Chenping noticed that Yun Wangyuan was in a good mood, so he asked.

"Seventh Order!" Yun Wangyuan didn't think about it, so he replied directly.

"Seven...... Seventh Order! Chenping was taken aback when he heard this, looked at the raunchy teacher in front of him fixedly, and asked suspiciously, "Teacher, don't be joking!" ”

"I'm not kidding!" Yun Wangyuan looked at the star energy converter and said regretfully: "Actually, this machine is usually used by myself, but after reaching the seventh order high level, I can no longer inject star energy into my body, so I just want to improve it!" ”

"I wonder what you're doing with this machine all day long?" Chenping said suddenly.

"It's a pity that there hasn't been any progress yet, it seems that more frantic strength is needed!" Yun Wangyuan said contemplatively.

"Why the power of madness?" Chenping asked puzzled, "I've always been surprised, the purer and gentler the star energy conversion in the mines, the better. In this way, it will not be too painful for users to use, and it will be safer. But what you do is really difficult, but on the contrary, to pour such a crazy power into people's bodies, ordinary people can't stand it at all! ”

"Have you ever been to the mines?" Yun Wangyuan asked.

"Well, I've been mining for a while!" Chenping replied honestly.

"Then you should know that the total amount of E-class star energy will drop dramatically when it transforms into D-class, right?" Yun Wangyuan asked.

"Yes!"

"Then when you disassemble the D-rank Star Source Stone and let it transform back to E-rank, can you return to the original total amount of Starlight?" Yun Wangyuan continued to ask.

"Of course not!" Chenping said.

"Why?"

"Because whether it is an F-grade star source stone or an S-level star source stone, they do not contain absolutely pure star energy, so in the process of condensing the star source stone, it is actually filtering star energy. The higher the quality of the Star Source Stone with more star energy, and the lower the quality of the Star Source Stone, the higher the other energy it contains! Chenping said.

"You know a lot!" Yun Wangyuan said with a slight surprise.

"This is common sense that every miner knows, okay!" Chenping said with a wry smile.

"Then you definitely don't know, in fact, the amount of star energy content in the star source stone is not important to the star pattern. Because the star stripe itself is the best star energy conversion tool, any energy that enters the star stripe will be slowly converted into star energy. Therefore, there is not much difference between an F-level star source star and an S-level star source stone for star patterns. What really makes a difference is the total amount of energy of the Star Source Stone and the absorption efficiency of the Star Stripe! ”

"......" Yun Wangyuan's explanation made Chenping stunned for a while, and he couldn't speak for a long time. In fact, this is a question that can be understood if you think about it carefully, but almost everyone ignores this fact!

"Do you know why?" Yun Wangyuan went on to explain, "Because most people are accustomed to absorbing star energy and ignoring other complicated energies! It's just a little bit of pain, what's the difference between the two energies? ”

The corners of Chenping's mouth twitched unconsciously, thinking that this difference is big! Who in this world is so boring that they abuse themselves when they have nothing to do? However, he didn't say it, because he knew that this teacher's way of thinking was different from ordinary people, and in order to achieve the desired effect in his eyes, he didn't care about his physical feelings at all. At this time, he noticed another thing, Yun Wangyuan's strength had reached the seventh order high level, but he could no longer advance, didn't that mean that he was stuck in the bottleneck of the eighth order?

"Teacher, are you doing this experiment just to advance to the eighth rank?" Although Chenping guessed, he couldn't help but ask.

"Well, I've used all the D, E, and F level star energy over the years, but after reaching the seventh order, I had to use non-star energy to improve my star energy, but unfortunately even these energies don't work now!" Yun Wangyuan said with a wry smile.

"Teacher, do you mean that this machine was originally started with star energy?" Chenping asked with a black line on his head.

"Of course!" Yun Wangyuan replied as a matter of course.

"......" Chenping suddenly had the urge to beat the other party. After forcibly resisting this impulse, he asked curiously, "Teacher, how did you support it?" With such a strong energy impact, I'm afraid that ordinary star stripes can't withstand it! ”

"It was true at the beginning, but after carving the seventh-level star pattern, all this will not be a problem!" Yun Wangyuan nodded and said in agreement.

"Listen to what you mean, teacher, you won't carve a seventh-level star pattern on yourself for the sake of doing experiments!" Chenping looked at this "genius" teacher dumbfounded.

"How do you know?" Yun Wangyuan asked slightly stunned.

"Whoa......" Chenping suddenly felt that this teacher was really a madman, and he actually did such a strange thing.

"I've always wanted to try it with nuclear energy, but the school is very strict about it. And after I mentioned it once, the principal often came to check and forbade me to do experiments in this area......" Yun Wangyuan said regretfully.

"I know that there is a place where there is a leak of nuclear energy or even a higher level of star core poison, I wonder if you are interested, teacher?" Chenping suddenly opened his mouth and said bewildermently.

"Where?" When Yun Wangyuan heard this, his eyes suddenly released infinite essence, and he flashed in front of Chenping and grabbed him tightly.

"Teacher, don't get excited!" Chen Ping pushed Yun Wangyuan away with a smile, and said lightly: "Use the entire set of star energy conversion technology to exchange, and you must not leave a little bit behind." And let me be the assistant of the experiment, and follow you all the way when you are promoted to the eighth rank! ”

"Okay! Take me now. Yun Wangyuan agreed without hesitation, and pulled Chenping to prepare to go out.

"Don't worry! If you want to go to that place, you have to go to the principal and ask for permission. "Chenping is really a little helpless about this bastard teacher.

"Will the old man agree?" Thinking of the old man of the principal, Yun Wangyuan had a headache.

"Looks like you don't know what's going on outside? Don't worry, he'll agree! Chenping said affirmatively.

"What's going on out there?" Yun Wangyuan asked curiously.

"Star thieves invaded the territory, and a nuclear bomb destroyed a military base......" Chenping briefly explained.

"What, so much has happened! But why didn't anyone tell me? Yun Wangyuan was taken aback when he heard this, but he also showed extreme indignation. It was too much for the school to tell him about such a big incident!

"......" Chenping thought to himself, I'm afraid you're the only one in this world who doesn't know this one! Anyway, the star thieves have all hit the Star Dragon Academy, and you, as one of the teachers, don't know anything, how irresponsible is this? Unconsciously, Chenping became more and more contemptuous of Teacher Yun in front of him.
