[Sys--... ini--tializing...][Err0r: M3m0ry c0rru--ion d3tect3d. Pr0c33ding 4nyw4y.][Miss10n: Unkn0wn. Purp0s3: Und3f1n3d. Proc33d.]Laverne never believed in the supernatural. To him, life was already complicated enough without worrying about things like ghosts or reincarnation. But when a reckless act of bravery ends in fire and chaos, he wakes up to something far worse than death—an unfamiliar world governed by an unfathomable system.Marked as an Anomaly, an existence that shouldn't be, he finds himself entangled in forces beyond mortal comprehension. The world he is reborn into runs on the concept of Ka, the essence of life and fate itself. Yet, unlike others, his Ka does not conform—it rebels. The system that governs this world struggles to define him, its very framework warping around his presence.With each step forward, he realizes that his mere existence is enough to tip the scales of destiny. Some will seek to control him. Others will try to erase him. But one truth remains:'In a world where fate reigns supreme, what happens when something stands outside of its design?'

In the first year of the fire calendar, a large-scale spiritual recovery has occurred around the world.

One year after the fire calendar, the Jingwei Division was established and began to contain supernatural beings on a large scale.

After three years of the fire calendar, Xun Xi traveled to this world full of despair. However, in front of him, there is only a diary written by himself before his death, who claims to be the future.

The diary revealed his future death.

In other words, every line and every sentence in the diary is his masterpiece.

And it will be updated!

“Others are the favored sons of the heavens who have traveled through the world. Wherever they go, they will be followed by chance. Why is it only me, where I will die wherever I go, I am just a rebel, a version orphan.”

“unfair!”

…………

Carrying a future diary in his arms, Xun Xi is struggling to survive in this desperate world. He firmly believes: My future style, I am the master!

- Description from novelbuddy

In a modern world where cultivators need a place to cultivate or vent their boredom, there are private businesses that set up instance dungeons with the aid of technology and cultivation magic to enable cultivators to train and commoners to experience the life of cultivation. They are called dungeon suppliers.
Xie Jin's one and only dream was to be a dungeon supplier and when his only relative passed away, the relative's inheritance gave him a plot of land and surprisingly, a 'System' Module which the relative had previously used.
With the help of the system, Xie Jin decided to pursue his dream of becoming the number one dungeon supplier.

The King Of Assassins was a monster that reigned over the world of hitmen for long years. He was the absolute peak that no other being could reach. His name reached the ears of every powerhouse in the world and sent shivers through every human.

Yet, his legend came to an end suddenly when he died in unknown circumstances.

However, instead of disappearing forever, he was given another chance in another world by the goddess of reincarnation. It was the world of an old book that he read back in the time. A world where everything was possible, where humans could reach new heights that were impossible in his old life.

But, this place didn't seem to be normal as it carried a huge surprise that will make his journey seem all the more interesting.

The Goddess of reincarnation wasn't as holy as anyone would think. She was nothing but a twisted being who found a toy to play with. The goddess manipulated the world that he was going to and changed all the heroines into these twisted beings that fit her character. They were all now harboring this unhealthy obsession toward him and trying with all their powers to take him away for themselves.
