A Monster from Undertale: Sans 来自传说之下的怪物:sans
After arriving in the Undertale timeline and becoming Sans, he gains the power of Causality Code and puts a stop to the player’s genocide run. He goes to the surface with Frisk and the others, only to discover that human scientists have also begun researching “soulology.” The source of it all is the anomaly caused by that player. But Sans has no intention of taking on a whole skeleton-load of trouble. Still, one thing after another comes his way, and Sans catches sight of versions of himself fro
