Survival: Falling Off a Cliff Activates the Sign-In System

Both of his parents died and he drank too much and went to the rooftop. After drinking, he fell off a cliff and hung on a pine tree in the middle of the mountain. With his skin and flesh torn all over his body, he crawled into a cave to hide from the rain, and touched a warm stone tablet in the darkness. The moment my fingertips touched the inscription, the system popped up: "The sign-in system is activated - the first day of sign-in will reward you with 'Beast Intuition', and the next day will unlock 'Basic Recovery'." I leaned against the mountain wall to catch my breath, and there was the sound of rocks rolling down above my head - the hole seemed to be collapsing.
