MTL - Rebirth of the Urban Immortal - Chapter 3857 do the opposite

The world was once at war with 10 alternate worlds. This was known as the Concept War and our world won 60 years ago. All of this was concealed so no normal people are aware of this fact in the current time.

After the death of his grandfather, the high-school student Sayama Mikoto is suddenly summoned by the giant corporation IAI. He learns this world is headed for destruction due to the acceleration of the Minus Concepts. To prevent this, negotiations must be undertaken with the survivors of the other parallel worlds so their 10 concepts can be released.

And so Sayama is caught up in the final battle to clean up after the Concept War which left behind so much enmity.

Ye Xiao was a superior cultivator in his previous life. The three factions of the realm kill millions of people every time they attempt to seize cultivation resources. Wealthy towns turn to wastelands in just a single night. They cover up their crime with an assertion that the towns were suffering from pestilence and disasters.

They forcibly hold all the resources for cultivation, monopolize all valuable practice materials, and keep outsiders from cultivating so that only their three factions could cultivate in the realm. Ye Xiao declared war against the three factions in retaliation for their actions. He fought alone and ended up dying in vain. However, he is reborn into the mortal body of a 16-year-old boy. He will use the powers he cultivated in his last life and slaughter his way back into the Realm. The story begins!

What happens when, in the midst of struggling to keep up with life, you suddenly discover that you were a princess in a past life? Now, you're just a waitress with a drunken mother and a pile of bills to pay. But deep down, you know one thing: you’ll find the stupid jerk responsible for ending your royal life, no matter what it takes.Alexia POV:Then there are the spoiled, narcissistic rich jerks who think their daddy's car gives them a free pass to treat women like objects. Not today, Satan. These guys are like walking perfume ads with egos bigger than their bank accounts. I swear, they should just marry themselves—they're clearly their own type.When one of those jerks lands at my table, I can smell the entitlement from a mile away. I don't even wait for the inevitable sleazy pickup line or the “accidental” brush of their hand against mine. Nope. I pawn them off on one of the other waiters faster than you can say “unpaid rent.”

Ye Qiu transmigrated to a world of barren wastelands. He obtained the 10,000 Fold Return System.
