- Description from Novelupdates

Humanity has been gradually transported to the Abyss by a bored god to compete against other races and monsters.The problem is… humanity failed. In a last desperate push the strongest survivors chose a comrade to travel as far as possible back in time.

Skilled, disciplined and merciless.

Liu Ye was a perfect killing machine for the underworld when he finally decided to step down and live a normal life. All of that for his lovely little sister who was his only family left.

Unfortunately, fate wasn’t on his side.

A forgotten debt forces Liu Ye to return to his past life but this time, in a new role. His Ex-lover, the heiress of the local triad, recruits him for something unusual— a VR Game called Avatar Online.

Elements? Abilities? Avatar?

Follow Liu Ye’s adventure as the world he knew changes upside down!

The second moon marked the beginning of a revolutionary change.

With the emergence of monsters and dungeons in modern society, and the ability users who fight against them, the world faces a shift in its paradigm.

It heralds the advent of a new energy source and the decline of traditional occupations.

Common sense thus becomes warped and imagination becomes reality.
