This novel is also known as [I was caught and brought back after using and tossing aside the Great Demon King of e-sports…]

Wei Xiao––the former rookie king of the league, now an accompanying player and tr*sh talk king, had a stupefied look on his face!

Someone bought 10,000 games with him!

200 yuan a game, for a neat and tidy total of two million yuan!

Wei Xiao: “Boss, you didn’t miscount the zeroes, right?”

“No.”

“You want me to accompany you to play 10,000 games?”

“Mm.”

Wei Xiao was amazed. But just when he thought he’d encountered a generous fool and was having a good time deceiving and playing with them, he discovered the other party’s identity.

This person actually turned out to be his previous captain, the one whose hands were tired from accepting too many championship trophies, the one who made everyone feel fear when they heard his name, the Great Demon King of the league, Lu Feng!

Wei Xiao: “I’m sorry for disturbing you, goodbye!”

Lu Feng picked up the little bastard who wanted to run, “Have you played around enough? Come back for training if you’ve played enough!”

Later on, Wei Xiao became famous in a single game. The host interviewed him, “How would you evaluate God Lu?”

Wei Xiao: “God Lu? Great technique, strong physical strength, and the most heaven-defying thing is his endurance!”

Host: “???”

How come the answer seemed to be a little strange?!

Blue Star has entered the extraordinary era, everything is evolving, and monsters are rampant.

Humans awaken their star souls in evolution to fight against raging monsters.

Zhou Xuan, who was doing odd jobs in the Demon Town Tower, accidentally awakened to an unscientific sign-in system.

Sign in on the ancient desolate beast and gain the power of the wild. Sign in on the weed spirit, and the star soul evolves into the nine-leaf sword grass.

The thousand-year black turtle, the ten thousand-year sea king, the immortal true phoenix, and the sky-swallowing dragon have all become the targets of his registration.

There are countless monsters in the Demon Suppressing Tower, Zhou Xuan signed in silently, and if he was not careful, he would be invincible.
