Myriad Realms Gatekeeper - Chapter 7 - 6 This is a Set-up!

Perhaps it is the choice of fate. As a senior otaku, Qian Lingfeng got the “steel shell system”. However, when he swept the world with the system, became a local rich man, made all kinds of beautiful women, opened a harem, and realized the ultimate fantasy of thousands of otaku, he found that things seemed far from simple!
When the end comes, biochemical zombies suddenly come down, fierce beasts are in power, bloodthirsty zerg roam to kill the world, and human lives are comparable to dirt. Where will weak human beings go in this world? Is humanity going to be extinct? Or … can an otaku save the fate of the human race?

Damian's life is bland, miserable and getting worse. After hitting rock bottom, he travel to another world. In an alternate Albion, he faces dangers and delights beyond anything he could have dreamed. The new and powerful sorcerer soon realises it will be a struggle to survive.

Everything functions in a cycle, be it an ant, bird, lion, human, or even a celestial body.This cycle initiates with one's birth and governs one's end, yet there exists the potential to surpass it.Among the billions of planets floating in the cosmos, destined to merely occupy a void, some have the capacity to ascend, reaching new dimensions, standing shoulder to shoulder with realms like Heaven and Hell.---Vlad, a young man, found himself ill-fitted in a world that scarcely offered him any luck, weighed down by a mysterious secret that initially seemed more of a burden than a boon.Yet, the powers he had dismissed as trivial eventually became his most formidable strength when the apocalypse broke, unleashing literal pandemonium as angels and demons walk among the human race.

I don’t know why I die, I don’t know why I live.

Divided hunters die of loyalty,

The witch who plays with emotions dies of love,

Cautious fortune-tellers die of trust.

The thief who steals everything has nothing,

The visionary who created everything never existed.

The traveler fell on his way home,

The twilight giants rest before dawn.

Lawyers sacrifice for order,

Judges forget the law.

The sleepless sleeps in the dark,

The corpse collector lay in the coffin.

We are guardians, and a bunch of poor creatures who are constantly fighting against danger and madness.

This journey is life and death.

While drowning was inevitable, they had struggled.

This is the worst of times, this is the best of times.
