MTL - My Turret Has a Caliber of Three Thousand Meters - Chapter 15 : "Old rule, pay in advance."

This novel is also known as I Possessed a Demon Sovereign

Chen Luoyang felt that something was wrong with his transmigration. After transmigrating, he possessed the body of the highest expert in the world, the Master of the Demon Cult, addressed respectfully as the Demon Sovereign.

Generally, aren’t supreme experts the ones that leave behind a wisp of their soul behind and occupy a new body of some miserable low-level youngster then they go on a journey of revenge and make a comeback?!

Or perhaps it would be transmigrating into a miserable youngster’s body and obtaining a cheat slowly walking the road to becoming a God?

But why did his transmigration seem wrong?

Now my environment is full of big shots and I feel like I’m going to be exposed!

It was the year 2169. The apocalypse finally arrived.

Global warming, zombies, nuclear war, all at once. Just one tipping point and the world itself would crumble.

Then, Nova Corp, a hegemon of the corporate world, seemingly convinced the global super powers into doing the impossible: Taking everyone online.

And they did. Everyone, poor or rich, was taken into the VRMMORPG: World Online.

A fantasy world where anything was possible. A utopia, unlike everything that the real world was.

But what was supposed to become a method of existence, became a battleground for supremacy. Companies, world powers, and the rich battled to become the greatest.

The disparity between the poor and the rich grew. There was no justice in this world. It took Darwin's words further than any other.

Jake, as poor as one could get, was caught in the rift, torn apart by the unfair system.

He was a dog of the Shadow King Guild, and even though he was absolutely loyal, in the end, the guild cut him off.

He was without an anchor and left in the cruel world. He knew no Utopia like the others.

But one day, when he opened his eyes, nothing was the same anymore.

Opening his eyes, he found himself ten years in the past. He was done being the henchman now. He was not going to let himself be used anymore.

Now, it was time for him to fight back. So what if the strongest were going to stand in his way? He was going to be unstoppable.
