After Fifty Years of Sign-Ins, the Elf Queen Discovered My Identity

After transmigrating to a world of swords and magic, Yu Ziyu found himself among the Dark Elves.

He thought an unremarkable life awaited him.

But to his surprise, he accidentally activated a god-tier sign-in System. He could sign in anywhere, with a chance of receiving precious rewards.

Signing in at his home in the Underdark earned him the template of a legendary master swordsman.

Signing in at the Well of Eternity earned him an Elemental Spirit.

Signing in in the Dragon Princess's bedroom earned him the dark magic forbidden spell, Great Darkness.

Guided by the principle that staying hidden was the best way to survive, Yu Ziyu quietly signed in throughout the Underdark for fifty years.

Then, fifty years later, an army led by the surface elves invaded the entire Underdark...

Facing the legendary Elf Queen and the Dragon King, Yu Ziyu knew he had no choice but to step out of hiding.
