Zombie World: I've signed in for 20 years, I'm invincible!

His physical body passed through the zombie world and was tempered by the power of time and space, turning back to the appearance of six or seven years old.

He followed Shi Jian, Lin Fengjiao, and the others to Mao Mountain and awakened his golden finger. God-level check-in system!

After signing in for 20 years, only after leaving the mountain did he realize that he was already an existence like a ceiling.
