World of Immortals - Chapter 123 – Taboo Ocean

​The world, Earth, was devastated by the Great Incursion, an apocalyptic invasion by dimension-hopping monsters. Humanity's only hope now lies in Galaxy Fall, a newly accessible parallel world where they can gain strength through a System of quests and missions.​Five hours after the Invasion, the betrayed survivor Mirabella is mysteriously reborn and gains a unique power: the [Master Account System].Her initial skill is the deceptively simple but devastating 'Multiplier x100', which applies a 100 times buff to all her offensive capabilities, including physical attacks, spirit energy skills, and damage-over-time effects.​Mirabella must now transform from a silent survivor into the world's most feared warrior, who was only scared of one thing, which is?“I Hope I don't run out of opponents in Both worlds.”

Humanity has been gradually transported to the Abyss by a bored god to compete against other races and monsters.The problem is… humanity failed. In a last desperate push the strongest survivors chose a comrade to travel as far as possible back in time.

He was the cold-blooded prince of the Jin country. Decisive and smart, he had looked down on the world with apathy and disdain.

She was his Wang fei, a person who had saved him in the past, but even he wouldn’t look at her.

When the fire raged and death claimed her, it was only then that she realized her existence was nothing but a joke from the beginning.

She opened her eyes once more after spending two years as a roaming, vengeful ghost. In this lifetime, Ye Zhen promises that she will be a different person. With a slight smile, she will ruthlessly trample on those who had schemed against her and lied until her demise!

Most importantly, she would let him experience the pain of an unrequited love; the bitterness of seeking something you cannot obtain!
