Yu Chengfeng moved, and quickly rushed towards Mu Zhengze, as if he could only see afterimages, but unfortunately, Mu Zhengze didn't raise his eyelids, and directly took out the high-radiation crystal energy cannon he made, Mu Zhengze snapped a few shots, and directly wrapped Yu Chengfeng in a strange ray, unable to move at all, if it wasn't for Mu Ange who had seen it before, I am afraid that I don't know what is going on, no way, if there is no special tool, I can't see all kinds of rays in the air at all.

Finding that he was imprisoned, Yu Chengfeng's expression was cold, luck with all the aura in his body, he wanted to break through this invisible confinement, but found that he couldn't do anything, he looked at Mu Zhengze coldly, "What did you do?"

Mu Zhengze shrugged, "No!"

"I just laid a colorful ray net around you, you can't break free with your cultivation, as long as you admit defeat, I can let you go!"

"Dreaming!"

"Are you sure?" Mu Zhengze's mouth hooked up a weird smile, "You can't see this colorful ray net, but you can use your spiritual power to perceive, you will perceive its existence, this is an invisible ray, it will slowly shrink until you suffocate to death!"

Mu Zhengze's expression looked terrifying, "So, are you sure you don't admit defeat?"

Mu Zhengze also discovered the gamma rays in the spirit stone in the process of research, so he thought of this ray bomb from the gamma rays.

Gamma ray energy is somewhere between nuclear and conventional weapons, and it is extremely powerful.

This energy bomb works by causing certain radioactive elements to decay rapidly in a very short period of time, thereby releasing large amounts of gamma rays, but without causing nuclear fission or nuclear fusion.

It does not cause a large amount of radioactive fallout like a nuclear energy bomb, but the lethality of gamma rays released is thousands of times higher than that of a conventional energy bomb.

For example, the energy bomb made by using the decay characteristics of hafnium, the energy contained in one gram of hafnium is equivalent to 50 kilograms of ZY, and the hafnium energy bomb does not need to use enough mass to reach the critical state like a nuclear bomb. As a result, gamma-ray energy bomb technology enables the development of warheads with smaller masses and greater power.

Mu Zhengze was inspired by this, and captured this similar gamma ray from the aura, which he called the spirit stone ray, of course, what was used to deal with Yu Chengfeng was still one of the defensive forms, and it would not produce a huge explosion, after all, they were a game, not a desperate one.

As the rays became more and more constricted, Yu Chengfeng felt the crisis, and a touch of coldness flashed in his eyes, but he couldn't do anything.

As he struggled faster and faster, the rays would only get tighter and tighter, as the saying goes, outsiders see the excitement, insiders see the truth.

Except for the students below who didn't know what was going on, a solemnity flashed in the eyes of the elders above Jin Dan, and the energy emitted from the black thing in Mu Zhengze's hand fluctuated very strongly, although he didn't know how Mu Zhengze did it, but there was no suspense in this game.

"Mu Zhengze, what kind of demon spell did you cast on Senior Brother Yu?"

Mu Ange sneered, "Yo, demon law, we are all ordinary people, but we don't know any demon law, if you want to talk about demon law, it should be you Senior Brother Yu, this standing motionless on the stage, with a hideous face, who knows what is going on with him!"

"Mu Ange, don't open your eyes and talk nonsense, it's clearly your brother's ghost, what is he holding in his hand, and what did he do to our Senior Brother Yu?"

Mu Ange snorted coldly, "What, forgot the agreement between Yu Chengfeng and my brother before?"

"You forgot, I'll give you a recollection!"

"My brother said that during the competition, he will use scientific methods to tell you that science and cultivation go hand in hand, and of course, he doesn't mind telling you that even ordinary people with high technology can still clean up your group of so-called monks!"

"You!"

Chao Wenyuan's face turned red, and Zhou Mingxi next to him pulled Chao Wenyuan, asking him to calm down and continue to watch the situation in the stand, this situation is obviously not good for Senior Brother Yu, if they talk about this now, it will only fall into the mouth, Chao Wenyuan snorted unwillingly.

Mu Zhengze looked at Yu Chengfeng with interest, " This is my latest research and development of a weapon, because the rays and bullets used are extracted from the aura, so I call it a high-radiation crystal cannon, a bullet can blast a city and kill a Jindan master, so I want to tell you that science is more powerful than you think, and the cultivation you are proud of is nothing to hide in front of science, unless you reach the cultivation of the elders, of course, at the same time, the weapons I research will continue to increase, it depends on who grows faster!"

Mu Zhengze suddenly withdrew the colorful ray net around Yu Chengfeng.

"As I said before, I will tell you that science and cultivation can go hand in hand, and this time I can still win you without using weapons!"

Yu Chengfeng's face turned pale, and he snorted coldly, "No need, I admit defeat!"

He, Yu Chengfeng, is not a person who can't afford to lose, this time he was careless.

Mu Zhengze was surprised, but he didn't expect that Yu Chengfeng would admit defeat so readily, which was not quite consistent with the rumors about him.

"Tell me, what do you want me to do?"

He hadn't forgotten their previous bet, and he was sent by you!

Mu Zhengze raised his eyebrows, "I don't need it for the time being, when I think of it, I'll look for you!"

Yu Chengfeng nodded, turned around and left the arena, this game was huge, but it ended in an instant, I have to say that Mu Zhengze's hand made the monks of the Otherworld Academy clearly understand the strength of the Blue Star people, even if they are not monks, even if they can't cultivate, they have scientific and technological weapons in their hands that they don't know, and they can still survive in this world where strength is respected.

When Mu Zhengze came down, the students of Blue Star Academy were all cheering, to be honest, they came here from Blue Star as exchange students, although they could learn a lot and get a lot, but in a strange world, a world where their lives were in danger at any time, they were looked down upon by the local people openly and secretly, they still held their breath in their hearts, if it weren't for the fact that they couldn't do it because of the regulations, they would have stopped doing it a long time ago, Mu Zhengze won this battle beautifully, see who dares to say that they Blue Star is useless.

If it is really useless, how can they Blue Star solve the negative energy that the cultivation realm cannot solve, therefore, cultivation has the benefits of cultivation, but science also has the benefits of science, it's just that the principles pursued by the two worlds are different.

"Boss Zheng, awesome!"

"Boss Zheng, you have done another big thing quietly, it's amazing!"

"Zhengzheng, thank you for fighting for our students of Blue Star Academy!"
