My Costar's shizun is not far
Finding his memories among billions of others feels to Yao Shen like an insurmountable task.
He wracks his brain for a way to find his memories faster, but nothing comes to him. He guesses the only way out is up.
He starts climbing, stopping every each step to check the vials.
Pretty quickly, he comes to the realization that the vials on the lower shelves are all older, so there's no point in him bothering with them. Although he can't be sure when his first life started he's fairly sure it didn't take him that long from dying, becoming a ghost king, to reincarnating for the first time.
He climbs higher, until he can finally read the characters on each vial. They all have names, sometimes dates (which helps), sometimes not.
Yao Shen can't help picking a few vials and inspecting them more carefully. "Newborn girl, died without a first name or family name on the same day she was born."
It sends a chill down Yao Shen's spine.
