This is why people who are traveling through time do not have golden fingers. Systems are divided into tangible and intangible systems. The ones that are tangible and have carriers are called golden fingers, and the ones that are intangible and have no carriers are called systems. Nowadays, because there are endless cheats stolen in various worlds, the system administration specially selects some people to assist the artificial system.
