Legend has it that Star Source Continent is a primitive world where humans and elves coexisted, created by a seven-star creation god. The development of science and technology here has not yet matured, and the elves have absolute suppression of humans. Eighty percent of the entire continent is controlled by various beast kings of the elves. The only remaining part of human territory is where elves and humans coexist peacefully. Establishing a contractual relationship with the elves can further enhance the relationship between them. Each human here can have up to six elves. And once a contract is signed, it cannot be abandoned easily. The elves are divided into seven stars, and the legendary creation god-like existence has long disappeared from human sight. The protagonist of the story is named Ye Bufan.
