One day, spatial tunnels opened in the very fabric of reality, connecting Earth to a planet that came to be known as Xavier, a planet that has a lot of deserted settlements belonging to the civilization that lived on this planet before we started exploring it.

Each settlement not only hides a secret of its own but also treasures, knowledge, and unthinkable technologies.

In this new world, magicians rule the world and make the rules.

They are those who can contain magic energy, an energy source present in Xavier, in their bodies.

This energy is used to mainly empower supernatural cells.

One can get them by consuming evolution materials.

These supernatural cells suck magic energy to manifest one's superpower in the real world.

Elliot, once the son of magicians in the channel opening stage, now lives the life of an orphaned and poor boy.

Elliot is the weakest magician to ever exist in the world, a world where the strong are respected and the weak are disdained.

With the death of his parents, the ones who used to look down on his has no reason to control their feeling.

With a dim fate ahead of him, he grits his teeth and silently moves on to the day the light of glory shines on him, setting him apart from others in a single day, letting him taste what it means to be God!

In order to avoid marrying an old man from the neighboring county, she must run away. The first time she escaped, the general entered the city, and she rolled and fell in front of him, no, she kneeled in front of him (really not on purpose). The second time she escaped, the general came to visit her house, and the general caught her (he must have done it on purpose). The third time, she was bruised and battered, almost desperate, and he came galloping and took her into his arms. (He was very well-intentioned.) The general said, ” Although I do not want to hold a favor to you, it is true that you owe me a favor.” So? 

 An Ruochen is unwilling to submit to fate and meets General Long three times when she runs away from home. She expects to get help from a powerful man, but she is involved in a secret conspiracy instead. Vicious family, a missing younger sister, a mysterious spy, and power struggles. An Ruochen becomes the key to solving the mysteries and becomes the core of General Long’s heart.
