I Picked up a Starry Sky Bead

Late one night in the second semester of his senior year of high school, Chen Yuan came home from school to study. When passing by a demolition site, he saw an old scavenger digging something in the rubble. When the old man saw him, he ran away in panic and dropped a small dusty bead. Chen Yuan picked it up and wanted to catch up and return it, but the old man had already disappeared into the darkness. The beads are very light, cool to the touch, and have subtle lines on the surface, like some sort of pattern. He felt it was a little special, so he put it in his pocket and took it home. That night, the beads blended into his eyebrows as he fell asleep. An old, intermittent voice sounded in his mind: "Little guy... Inheriter... Weapon sect... Starry sky..." Chen Yuan woke up and found that his consciousness could enter the inside of the bead - a desolate space with a radius of 100 meters. The sky was gray, the ground was cracked soil, and there was nothing. But there are six light groups at the edge of the space, which read "Qi Refining", "Nianshi", "Physical Cultivation", "Martial Arts", "Elixir" and "Forging" respectively.
