Sign-In System: I Am Invincible in the World of Immortality

Teng Xiu was originally a modern grassroots. After a car accident, his soul traveled to the world of immortality and became a teenager. As a casual cultivator, he relies on the sign-in system to obtain resources. In this world of cultivating immortals, Teng Xiu started his counterattack from being useless. He encountered competition for resources, obstacles in his cultivation, and was maliciously targeted by his opponents, but he was positive. Accompanied by his best friend Ji Yuan, he practiced hard and crushed his opponents in sect battles. After obtaining a treasure, his strength greatly increased, and finally he participated in a cross-border battle to resist the invasion.
