You Liangxing would never open the speech function in game.
That was because his voice was…
Particularly! Kittenish!

But there was one day, he queued up with a teammate who had so much to say that they may as well explode. Vexed to the point of no return, he contributed a voice that was capable of splitting heaven and earth, “Don’t BB.”
The other party who was being scolded stilled. In the ensuing silence, he suddenly let out a long, relishing… Moan.
You Liangxing: “…..”

Later —
He realised that the person was a great god,
Much later,
Without him realising,

The leader of the thousand demons, the Demon God Chun YeoWoon. Due to an unfortunate accident, he had been sent to the distant future.

Kai is the hardest working warrior in his generation... and the unluckiest. In a world where most people receive magical skills, classes, or cultivation, Kai has nothing but his wits and his strength. His only choice will be to forge a new path against fate, no matter where it takes him.

Savage monsters pour endlessly from the wasteland, threatening the survival of civilization itself. They say that human strength isn't enough and only those gifted with destined powers have a chance of making a difference. Kai is hungry to fight in that war, to be someone who matters. That hunger will take him across a world stranger and more terrible than he could possibly have imagined.

The leader of the alliance, Song Zhaolan brought a group of martial artists to besiege the demonic sect. Suddenly the whole alliance and the demonic sect had crossed over to be the students of Class A and Class F.

So this group of people climbed the wall and went to the Internet cafe, stayed up late to read novels, and participated in the sports meeting with 18 kinds of martial arts…

The students at Wulin No. 1 Middle school were going crazy. Every day, they trembled under the authority of these two big bosses. They were caught in the middle of these two classes that were sanctioned with iron fists. There were no longer mandarin ducks in the grove, only the two bosses shouting at each other.

Finally one day, Song Zhaolan received the demon’s “letter of surrender”:

“Who says that good and evil do not mix? I insist to exist in your heart!”

Class A student: The alliance leader is mighty, he actually captured the right palm of the devil with one hand!

Class F student: The leader has a good heart, he actually used his mouth to save this scumbag!

BCDE student: Are you blind or mentally disabled? ? ?
