Cross the Border and Become an Immortal

"You thief!" "I didn't, I smoked openly." "You robber!" "I don't have it. The spiritual energy flows by itself." "Then you dismantle the Reiki station!" "I put so much effort into building it. If you want to dismantle it, you have to dismantle it yourself." "I'll dismantle it if I want... What are you doing? Take the cannon back for me!" "Everyone saw it. He struck first. I was acting in self-defense." ………… The world in which the Federation is located is lacking in spiritual energy. However, after exploration, it was discovered that there are special passages throughout the Federation that can lead to another traditional fairy world with rich spiritual energy. Relying on the development of psychic technology, the Federation established spiritual energy stations at these passages to extract spiritual energy from the other world and supply it to the Federation. This behavior will undoubtedly cause dissatisfaction in that world. The two parties will take this as the main conflict and start a story of traditional immortals and modern immortals confronting each other.
