I became a professor in a game by accident. To make matters worse, I even messed up the difficulty settings. Now, I’m stuck playing on Hell Mode. A world on the brink of war with the Demon King. An Assassin Department where mu*der is legal… as long as you aren’t caught. I thought I’d have to claw my way through just to survive in this wretched place, and that was the case at first. But nowadays… “No matter how hard I try, I can’t be like you, Professor… How do you do it?” “Please… become our god.” “What do you know? What is it you know? Why do you make me want to live…?” One by one, everyone at the academy began to obsess over me.

WARNING: The MC is NOT a demon! For an explanation of the title, please see the post we made specifically addressing this matter.

Ling Xiao was an orphan fighting for survival in a dog eat dog world. There were some who had the power to enjoy a life of comfort, unconcerned with worldly matters, while most struggled to survive. He was of the second kind.

When he celebrated his sixth birthday, his father left him to the wolves with only a token to defend himself. He struggled to earn a living, scrambling together whatever scraps he could gather; fighting with the dogs for food and fighting with the homeless for shelter.

But that all changed on a fortuitous day, when a demon invaded his home. In a world of deception and plotting, one tasked with seeking revenge for the man who gave him a second lease on life, how would Ling Xiao fare?

Qi Ming woke up to find that he had transmigrated. He had become a disciple of the Green Cloud Peak, one of the twelve peaks of the Heaven Enlightenment Sect. Fortunately, the “AFK Farming Software” was activated and changed his life.

“Ding!”

“You had been AFK Farming for seven days in the game dungeon ‘Shu Mountain Ancient Path’. You have cleared the game dungeon seven times. You have obtained: 1 Seven Star Sword, 1 Sword Kinesis Technique, 1 Top-Grade Foundation Establishment Pill, and 630 Low-Grade Spirit Stones.

“Ding!”

“The Green Cloud Qi Refinement Art has been cultivated for a day. Your cultivation progress has increased. You will break through to the next level after 10 days of AFK Farming.

Qi Ming was tired of cultivating. It was too dangerous out there, so he could only cultivate through the AFK Farming Software every day in the sect.

Eventually, Qi Ming reached Foundation Establishment, followed by Golden Core, and subsequently Nascent Soul. He... became invincible?
