Supreme Sign In, I Am Invincible

[No heroine, unlimited sign-in, invincible] An accident caused Su Yang, who was originally a social animal, to travel to a world full of dangers, but he awakened to the sign-in system, which allows unlimited sign-ins.

"Ding, congratulations to the host for signing into the Eye of Prediction!" As long as he keeps signing in, he will be invincible...
