The container core was secretly developed by White King Worm. When he ran away with the White House, due to various reasons, the core ended up in another human country.
After the protagonist died of starvation, his soul traveled to this other world, and happened to travel to the body of an experimental subject. He was forced to have his core pressed in this way.
After the core was implanted, he was instantly eroded, and his memory became damaged. He only remembered his experimental codename, Xiyue, and was later used as a weapon by the experimenter.
