Summary Version 1:

The mysterious boy Ling Chen is saved by a little girl as he lay on the street dying. Years later, he strikes a deal to save this savior-turned sister and enters the virtual world. In a future Earth where advanced warfare has forced nations to settle issues virtually or else suffer the consequences, Ling Chen bursts into the scene and goes from unknown to legend. Yet all is not as it seems, for Ling Chen has a dark past, and there is a greater mystery at hand behind this virtual world.

Summary Version 2:

To save his terminally ill little sister, Ling Chen enters the newly released virtual game world and joins a small gaming studio comprising entirely of women. From now on walking upon his path towards the pinnacle. An ancient, evil item almost forgotten by history, the “Lunar Scourge” helps forge his unsurpassable legend, and causes him to unknowingly step upon a path that is destined to be punished by the heavens, the way of the shura.

Yan Wushi had walked a path full of blood and corpses.

He did not believe in the good nature of humanity. Even more so, he did not believe that there could be someone with great kindness and sense of justice, who would be so considerate of others without asking anything in return.

One day, Shen Qiao, who was the sect leader of Mount Xuandu, the number one Daoist sect under the heavens, was challenged to a duel but somehow fell off the cliff.

Yan Wushi happened to pass by down there.

Seeing Shen Qiao who was seriously injured to the point of dying, he suddenly came up with a perfect idea…

After thousands of autumns, who could stay eternal?
