Toaru Majutsu no Index: New Testament - Volume 8, Chapter 4: Disaster in the Depths of Fertility. Goddess_of_Fertility.

Being a bottom feeder in society is an unpleasant experience.That's how Kiro felt after being left for dead in a back alley. Abandoned and disappointed by the 'work hard' ethic his parents left for him.'At least the heavens are weeping for me.' As the light from his eyes faded, he declared as the last act of defiance.He awoke in a room he hadn't seen in ten years. Whether it was due to sheer luck or divine intervention, he was grateful.'Through the VR game, Asgard, I'll become filthy rich in this life time.'Kiro was blissfully unaware that his return was a cry for something greater, for the underlying threats that hovered over his world.

Life used to be so simple,

Full of false hope and endless beliefs in one’s ability in wooing that beautiful girl.

But in a single instant,

Everything as you knew it, plummeted faster than a spoken rejection.

What is real and false can’t be determined,

As the world slowly falls into the maws of the apocalypse.

How will our simple friend respond to the call; the summons?

No matter what he chooses,

Chaos SHALL Reign!

Xiang Yu was perfectly content with his mediocre life on Earth—average job, average apartment, average everything. That is, until he woke up in the legendary World of Cultivation, where martial artists fly through the skies and immortals battle over ancient treasures.There's just one problem: Xiang Yu wants absolutely NONE of that action.Armed with only his wits and a peculiar system that doubles his exp every 24 hours, Xiang Yu has one goal: become powerful enough to live in peace without getting involved in those ridiculous “protagonist” situations. No ancient tombs. No tournament arcs. And for heaven's sake, stay FAR away from anyone named Chen Mo, Lin Feng, or Li Yao—those names practically scream “main character who will drag me into deadly situations!”Starting with strength stats so pathetic he can barely lift a cultivation manual, Xiang Yu must somehow survive long enough for his exponential growth to matter. After all, doubling zero cultivation talent still equals zero... at first.Follow Xiang Yu on his hilarious journey from zero to hero as he desperately tries to stay invisible while his power skyrockets beyond control! Watch as he dodges cultivation tournaments, avoids suspicious elders bearing gifts, and runs the other way whenever someone mentions “ancient inheritance” or “chosen one.”Join the adventure of the most reluctant cultivator in history whose only wish is peace and quiet, but whose exponential growth makes him the most terrifying force this cultivation world has ever seen!
