A veteran player of “Starry Abyss” and a Meteor Fall Master known as Ace Bro, Li Zi came to the game world with his system template, arriving at the era of the game's beta version.This was the worst of times.Cosmic forces and financial magnates colluded, causing The Gate to the cosmos to be shut, planets' resources exhausted, even sunlight monopolized.It was also the best of times.All the Extraordinary Systems had just started, and in this era, only he possessed the final version patch as a Meteor Fall Master.While people reveled in the smoke of plasma cannons, Li Zi had already torn apart warships with Gravity.As Special Ability users proudly indulged in their awakened abilities, Moonlight had already become a servant to Li Zi.When the Interstellar Fleet crossed the Galaxy, Li Zi had just ignited the forty-second Stellar, illuminating the entire cosmos.“People have been trapped on the ground for too long and have forgotten that this Starry Sky should belong to us all,” he said gently, holding a black hole in his hand while facing an indescribable native Evil God.

There are a total of seven sins, and a revelation is made to a young man named Alex that he is destined to become a demon lord, more especially a demon lord of sin called LUST.

It's not like he can change that and because he always knew something about himself was different—not in a physical sense, well, maybe a little—and not in a mental sense—but rather because he is thrown into a demonic war that compels him to accept his new reality.

He was only aware of a difference in himself. Relating to him and the ladies who are drawn to him... Well, it was more or less like he was a magnet in front of all the girls, and all the girls were drawn to him like a metal.

The formless ancient world was infested with despicable demons. They hunted and feasted on mankind, keeping the human civilization constantly in a weak and suppressed state.

During the first known year, a magical mountain descended into the world from the realm of the Gods. Carved on this enormous mountain was a message: ‘Heaven Prevails’…

After the Grand Descent, a name that was given to the descending of the mountain, the Three Great Sages made their ways to Mystic Mountain where they learned to harvest what we now call magic, establishing the Mystic Cults and eighty-one sacred shrines to help aid mankind with the cult’s mystic powers against the eternal fight to the death with demons.
