Classmate, You Dropped Your Superpower

Xu Ye's family runs a scrap recycling station, and since childhood, he has been good at picking up things others throw away. On the first day of university registration, he picked up a shard of glass that only he could see. Within three seconds, a falling beam stopped mid-air. After the beam landed, its owner, Shen Zhiwei, blocked his way: "Classmate, did you pick up something of mine?" Xu Ye then realized that some people, under strong emotions, would "drop" their not-yet-awakened superpowers. The shard could be used temporarily in his hands, but it had to be returned within seven days. If the deadline passed, the owner would permanently lose an emotion or instinct; and to complete the return, the owner had to personally make the choice they were most afraid of making. Each time he returned a shard, Xu Ye could keep a weakened "echo." For the first shard, someone was willing to pay fifty thousand yuan. In the transaction photo the other party sent, Xu Ye was pictured without the shard he hadn't sold. — Description from novelcodex.org
