Just when everyone thought that Li Kai must be crippled, a man in black quickly bypassed the crowd of onlookers like the wind and came to Li Kai, only to see him slowly stretch out his palm upwards to block in front of Li Kai, and an invisible vitality was clearly visible on his palm and flowed slowly.

The huge claws of the Thunder Tiger were in stark contrast to the small palms of the man in black, and in everyone's opinion, the actions made by the man in black were nothing more than hitting a stone with an egg to the huge Thunder Tiger.

"Boom ......"

When the claws of the Thunder Tiger touched the palm of the man in black, an invisible sound resounded in everyone's eardrums, and everyone present was shocked by the scene in front of them, and at this moment, everyone probably had only one question in their hearts, that is, who was the man in black?

"Are you?" When the man in black appeared, a bunch of questions rose in Li Kai's heart, but when he faced the black, Li Kai only felt a sense of déjà vu.

"I'll clean you up when I'm done cleaning up this brute. The man in black said sharply to Li Kai.

"You are Teacher Xu. When I heard a familiar voice, I remembered Li Kaimeng for a moment.

The man in black didn't pay attention to Li Kai, but looked at the Thunder Tiger not far away with a smile.

Seeing that his attack was resisted by a short human, the Thunder Tiger suddenly became frantic, raised his head and stretched out his claws to attack again, and the roar that tore through the sky seemed to tell the anger in his heart.

Just when everyone thought that the man in black just now was just lucky to barely catch the attack of the Thunder Tiger, they found that the man in black looked at the Thunder Tiger acting like this, and the corners of his mouth moved slightly, revealing a disdainful smile.

I saw the man in black stretch out his hands, and with a fierce force, two black whirlwinds suddenly appeared on his palms, although the whirlwind was not big, but the powerful air flow brought by the rotation filled everyone's side.

At this moment, Lei Zheng, who was carried away by anger, also became sober, there are many Yuan Qi masters who can catch the attack of the Thunder Tiger at North China University, but the only Yuan Qi master who can be so skilled and release two whirlwind bombs at the same time is probably the only Teacher Xu in the Academic Affairs Office.

"Thunder Tiger is coming back soon. Lei Zheng, who reacted, just wanted to call his guardian beast Thunder Tiger back, although Thunder Tiger was a Xuan-level demon beast with strong strength, but facing Teacher Xu in the teaching office had almost no chance of winning.

But it was all too late, the claws of the Thunder Tiger attack were already hanging in the air, and Teacher Xu's whirlwind bomb was also ready, and victory or defeat was only a matter of moments.

I saw Mr. Xu wave his hands violently, and the black whirlwind with strong pressure rushed away like a pouring flood beast, and the speed of the black cyclone was so fast that it produced a piercing sonic boom, and if you looked closely, you would find that even the space around the cyclone was slightly distorted.

The sharp giant grasp of the Thunder Tiger began to collapse and fall the moment it touched the black cyclone, and the black cyclone gradually expanded, and finally expanded to the whole body of the Thunder Tiger, and the originally arrogant Thunder Tiger actually let out a burst of wails.

When they saw the scene in front of them, everyone gasped, what kind of strength could completely defeat such a huge Xuan-level demon beast, no one knew what happened to the Thunder Tiger in the black cyclone, the only thing for everyone to see was the claws of the Thunder Tiger.

"Teacher Xu, please let go of my Lei Minghu!!" When he saw that Lei Minghu was completely defeated by Teacher Xu, the last line of defense in Lei Zheng's heart also collapsed, and the domineering Lei Zheng finally put down his identity and begged Teacher Xu to let go of Lei Minghu, Lei Minghu was Lei Zheng's partner since childhood, and he really didn't want to lose it.

"Hmph. Teacher Xu snorted coldly, and then gently supported his sleeve with his right hand, only to see that the black cyclone disappeared out of thin air.

With the disappearance of the black cyclone, the huge body of the Thunder Tiger was gradually revealed, and the Thunder Tiger, who was still angry just now, wilted like a frosted eggplant, and the claws of his limbs were placed at will, and his huge body collapsed to the ground, staring blankly ahead, only the claws that were stretched out just now were hung with blood, and the other parts were intact.

Seeing this scene, Lei Zheng almost trembled and was about to cry, and the Lei Minghu, who had never been injured, made Lei Zheng feel very uncomfortable.

"Lei Zheng, the school clearly stipulates that fights are not allowed, do you know what you are doing?" Teacher Xu sternly restrained the trembling Lei Zheng.

"Me?" Ray was standing there speechless.

"You don't have to say anything, I can see it all, and my classmates can see it clearly. Teacher Xu stretched out his hand to stop Lei Zheng who continued to speak.

"Hey!!" Lei Zheng lowered his head and withdrew the guardian beast Lei and sighed deeply.

I saw Teacher Xu turn to Li Kai, who was still sitting on the ground, and said, "Are you okay?"

"It's not a big deal. Li Kai endured the pain in his body and barely smiled.

"If it's okay, just follow me to the Academic Affairs Office, and you, your ......" Teacher Xu pointed to Zhou Hai, Lei Zheng, and the two of them who were in place.

"Me?" the two asked in unison.

"That's right, it's you, I've already informed you about this Teacher Huang Xue. Teacher Xu gently shook his head, which was about to be bald, with his hands behind his back, and sighed lightly.

Li Kai struggled to stand up and walked behind Teacher Xu's buttocks, Lei Zheng also put away the injured Lei Minghu and drooped his head to keep up quickly, followed by Zhou Hai. Zhao Yu, Tang Xin.

The impact of the fight in the library pavilion was very bad, although there were no casualties, but the blatant provocation of the school rules of North China University was still very serious, but when Li Kai and the others were brought into the academic affairs office by Teacher Xu, no one cared about them, as if they were treated as air.

"Brother Kai, what's going on?" After almost an hour, there were still no teachers coming, and Zhou Hai was a little breathless.

"Wait, what else can I do, the teacher must be busy. Zhao Yu looked at Zhou Hai and said angrily, if it weren't for Zhou Hai pulling him, this situation would not have occurred now.

"Nonsense, who doesn't know that the teacher is busy. Zhou Hai asked rhetorically.

"Can you two be quiet, I'm still hurt. Li Kai yelled at the chattering duo on the side.

Li Kai always knew that there was a gap in strength between himself and Lei Zheng, but he didn't know that the gap was so obvious, although this time the fight was stopped by Teacher Xu in time to save Li Kai from serious injury, but it unconsciously left a shadow in Li Kai's heart.

The room, where there was no voice, suddenly became so quiet that even the teacher's voice could be heard clearly.

"Teacher Xu, what do you think we should do about this?" said a girl.

"There are documents on it, and this academic exchange represents the honor of our North China University, but the school we are about to go to is a little remote. The boy replied.

"Remotely, where?" the girl asked.

"Cangyu City. The boy replied.

"Where is it, it's biased enough. The girl said in a tone that I understand.

Li Kai wanted to listen to the words of the two again, but found that he couldn't hear clearly anyway, this was the door of the classroom suddenly rang.

"Squeak......

As the door was pushed open, I saw Teacher Xu and Huang Xue walking in one after another.
