Qin Yunfei performed this set of gun skills, which can be described as amazing.

Those senior brothers were all stunned.

"What kind of soul skill is this? Is this kid metallic or fire attribute? Why don't I feel the star soul power fluctuations in his body?"

"Teacher Su, what the hell is going on?"

A group of students knew that Qin Yunfei was not easy to mess with at this time, so they all asked Su Xinghe with some doubts.

At this time, Su Xinghe stepped forward, he looked at Qin Yunfei carefully for a while, and then asked, "Are you Qin Yunfei?"

Qin Yunfei arched his hand neither humbly nor arrogantly, "Yes, the student is Qin Yunfei." I don't know what the teacher is called?"

The teacher smiled from ear to ear, quickly pretended to be a gesture, and stroked his beard with his hands.

"I am the vice president of our school, Mr. Su Xinghe. If you have any ideas in the future, you can come to me. You know what?"

Hearing that it was Su Xinghe, Qin Yunfei was taken aback, but after thinking about it, he still said, "I estimate that I will often trouble Mr. Su in the future." ”

Hearing him so polite, Su Xinghe was in a good mood, and stepped forward to take Qin Yunfei's arm, about to go to the laboratory.

"Let's go, tell me what those shoes are for. I'm really curious. ”

He forced Qin Yunfei in front of everyone and pulled Qin Yunfei in again.

And those students in the inner courtyard, at this time, were dumbfounded.

"What's going on? This Teacher Su burned his brain with alchemy, right? He asked us to stop this kid from leaving, why did he stop people, and he ran away with people instead?"

"Forget it, we can't afford to provoke us, can't we hide? Next time he looks for us, won't we do it if we don't make a move?"

So, this group of students cursed Su Xinghe, and then they each supported each other and went back to the dormitory to rest.

And Qin Yunfei and Su Xinghe, who came to the classroom here, sat in front of the podium at this time, with different expressions.

This Qin Yunfei looked helpless, but Su Xinghe was extremely curious and asked.

When Qin Yunfei explained the principle of the roller, Su Xinghe was shocked.

"It turns out that metal balls still have this kind of use! Why didn't I think of it before? It's just this kind of shoes, can I really wear them? Will it be easy to fall down when I wear them?"

So, Qin Yunfei gave him another demonstration of skating movements.

This old man immediately respected Qin Yunfei like a heavenly man.

"This ...... This is really a new feat! This is a design that is even more amazing than making a dragon car! And the whole structure is so mysterious and complete, it is simply a miraculous creation!"

However, Su Xinghe said, and suddenly asked curiously, "Yunfei, how did you think of this roller?"

Qin Yunfei didn't know how to explain it, this roller, in that world, seemed to have become the most popular mechanical part for a long time, how did it come here, it became such a mysterious thing?

He didn't know how to explain it, so he lied.

"It was passed on to me by my master, and I still have a lot of design drawings for this kind of design thing, but I didn't design it because it was too troublesome. ”

It's okay if he doesn't say it, but as soon as he says it, Su Xinghe is even more shocked and trembles all over.

"That's great! In this way, my Dragon City Divine Machine Academy is about to become the best organ academy in the Longhua Empire! At that time, the decision-making in the Divine Machine Pavilion will not be subject to the dispatch of our Dragon City Divine Machine Academy?"

Thinking of this, the teacher and vice principal excitedly shook Qin Yunfei's hand, and he was so excited that he couldn't wait to call Qin Yunfei a brother.

"Yunfei, you just came to our school, and you have made such a great contribution!

Qin Yunfei was stunned for a moment, this vice principal, why did he want to reward himself as soon as he opened his mouth?

But don't be in vain, people are so kindly invited, if you don't accept it again, wouldn't it be unkind?

Therefore, Qin Yunfei smiled and said, "Dean, I just came to the school, I heard that there will be a big auction at the orientation party tonight, and now ......."

As he spoke, Qin Yunfei gently rubbed his fingers.

Where does this Su Xinghe not understand what he means?

"It's easy! There's 500,000 soul coins here, you can take it. ”

This Su Xinghe is really generous, as soon as he opened his mouth, it was 500,000 soul coins, which really shocked Qin Yunfei.

It's just that Qin Yunfei was just about to pick up the money, but he took the money back.

Qin Yunfei frowned and said, "What does Dean Su mean by this?"

Su Xinghe smiled faintly, "I gave you money, you have to donate the design drawings to the school, including the right and left hand weapons you just now, you also need to donate to the school." Do you think it's okay?"

He wanted to design the drawing, which obviously made Qin Yunfei a little unexpected.

However, he really didn't care about these two things, one was a toy, and the other was just the key to the era of thermal weapons.

So he took out the two design drawings to the other party, and at the same time, told the story that the design of his roller skates had been given away.

When the old dean heard that this was not his first blueprint, he was a little disappointed, but he did not regret it.

"Good boy, you actually used this kind of second-hand goods to coax me 500,000 soul coins. I'm going to have to watch out for you. Su Xinghe looked at Qin Yunfei with a smile.

At this time, Qin Yunfei said with a smile, "Don't worry, dean, although I gave them the blueprint, I still have something that I want to study with our school." ”

As he spoke, Qin Yunfei took out the design drawings of the Feiyun.

He handed it to the vice principal, who was stunned at first when he saw that the drawings were so large.

When he finished reading the blueprints, he lost his strength and sat on the chair.

"This ...... How many people's efforts would it take to design such a complex machine? Even the Iron King Kong left behind by the Star Soul Emperor back then is not half as complicated as this, right?"

When Su Xinghe sighed, Qin Yunfei actually heard the words "Iron King Kong" from his words.

Qin Yunfei asked, "What is this Iron King Kong?"

Su Xinghe couldn't bear to ask, and briefly explained what Iron King Kong was.

It turned out that before the death of the Star Soul Emperor, he left his will on a vajra puppet forged of black iron, and to this day, this puppet is still teaching future generations how to use the art of mechanism.

Hearing this, Qin Yunfei was shocked in his heart, so he asked, "Do you mean to say that this Iron King Kong is now the source of our academy's knowledge system?"

Su Xinghe nodded and said, "Yes." It is because of this that the academy is now divided into two factions, one is conservative and the other is innovative. ”

Speaking of these past events, Su Xinghe couldn't help but sigh.

"Speaking of which, our inner court is not a day or two. ”
