Quick Transmigration: NPCs Never Give Up!

[Male protagonist, no romance] [Amnesia and power-ups] [The protagonist is nonhuman at first] A stone from the start, and saving the world depends on teamwork?! Help! What do you do when you wake up and find yourself a stone beneath a treasured sword? Shi Yan says, “What can I do? I’ll just go with the flow.” But the brave hero is supposed to save the world, so why does he seem so dim? And why do all of you act like you know me so well? Who are you people?

Arc One: Western Fantasy, Sword and Sorcery (Hero × Stone, Ren Yichu × Shi Yan)

Arc Two: Ancient Times (Emperor × Imperial Preceptor, Shi Yan × Bu Wenxin)

Serious version: The one who has forgotten seeks the truth, while the one who knows everything conceals it. The cycle begins anew. When the amnesiac hero draws the holy sword, the stone beneath it feels familiar. When the task-taker who longs to return home touches the truth, he discovers that everything is merely a dream woven by higher dimensions. Instinct remains engraved in their bodies, while the memories of the past scatter like dust. When the call to rebel sounds again, this time they will write their own ending.

(A fake) sunny, cheerful, wisecracking protagonist
