Toaru Majutsu no Index SS - Volume 2, Chapter 14: The Dance between Gatekeeper and Intruder. The Third Friday of September.

“Before the towers fell, before everything was consumed by darkness...”Leo Astralis whispered to himself while traversing through the rubble of the ancient structure.His body bore the scars of survival, bite marks that throbbed against the coarse, blood-stiffened fabric of his clothing.“..I wonder what the world was like.”After humanity failed to complete the Tower almost 700 years ago in time, it exploded, spreading monsters all over the word.Even the system, which blessed humans with power, had abandoned them. Or did it?[Run]A singular message urged Leo to escape, yet it was short lived as was he was caught like an animal in a trap.And just like an animal he lashed out until the very end, taking one of the captors to the grave with him.But as darkness closed in, the system spoke again.[One time Regression activated][Congratulations. You've activated the Heart of the System]

Mediocrity is the normal state of most people, and some of them can’t even reach the normal state~ A young man from a small town, ugly and inferior, disliked by relatives and friends, mediocre grades…

All these changes started with a beam of light going to the university train, and the boy was bound to the high-quality male god system.

The days are getting more and more hopeful, and the system is really fragrant:

As long as you learn, you can modify your own bugs;

As long as you do good deeds, you can get corresponding banknote rewards;

As long as you are praised, you can get relevant talent blessings;

…

This, it’s hard not to love, okay!

Upon awakening, Lu Xuan found himself as an ordinary spirit plant cultivator, tending to an acre of land merely scraping by in the realm of cultivation.

Fortunately, he stumbled upon an unexpected revelation: with each maturing spiritual plant, he received additional rewards.

Harvesting a The Firefly Grass yielded a Golden Sword Technique.

From the Blood-Devouring Vine, he obtained a Purification Talisman.

And the Phantom Spring Flower gifted him a prescription for the elusive Luminous Flame Pill.

Henceforth, he contentedly tended to his own spiritual fields, observing the tumultuous tides and shifts in the world of cultivation.

“Duels and clashes, expeditions into secret realms, immortal fortunes, obtaining mystical treasures… None of it concerns me!”

“I simply wish for peace and quiet to tend to my fields.”
