The Grind King

The Grind King: I Cultivate My Way to Becoming an Emperor for the Ages

Jing Yan is reborn as the most good-for-nothing prince on a fantasy continent. His brothers bully him, the palace servants look down on him, and his cultivation aptitude is ridiculously poor.

Then he binds himself to a god-tier grind-king System: one minute of cultivation for him equals a full day for anyone else, and he can even exchange experience points for anything.

While the other princes struggle desperately to break through bottlenecks, Jing Yan quietly cultivates in seclusion for ten years. When he emerges, he is already at the fifth tier, with every star maxed out.

When enemy armies lay siege to the city, he stands atop its walls with a sword in hand, backed by an army of a million grind kings who have all cultivated in deathly seclusion.

After uniting the continent, Jing Yan gives a faint smile to the enemy rulers kneeling and begging for mercy:

“It’s not that I’m too strong. It’s that I made up for all the time you wasted slacking off during cultivation.”
