After Ten Years of Haki Training, I Finally Learned Demons Exist

Blind for ten years, he only then discovered that demons existed in the world. Jiang Ye transmigrates into a world of demons and becomes a naturally blind child living at his aunt's house. From the start, he binds a System and unlocks Fujitora's template from the vast world of seafaring. Hoping to improve his quality of life, he trains his Observation Haki day and night for ten years, unknowingly mastering it completely. One day, a demon enters the town where he lives, and he casually cuts it down. Only then does Jiang Ye realize: this world... really does have demons! And all he has to do is kill them to earn all kinds of rewards.

“Slay the Snake Beauty, reward: Haki +10.”

“Slay the Tiger Demon, reward: Golden Light Spell.”

“Slay the Black Mountain Demon King, reward: Pure Yang Flame.”

And so, the world gains a blind youth wielding a cane sword. Wherever he goes, demons are wiped out.
