This is an age of Soul-Weapon Masters. By contracting soul weapons, people can wield extraordinary powers. Li Yuan is lucky: at eighteen, he successfully summons a powerful epic-grade soul weapon. Once the contract is complete, he’ll become a Soul-Weapon Master with a limitless future. But Li Yuan is also unlucky. He has grown up in a suffocating household, and the moment he summons the epic-grade soul weapon, his adoptive parents force him to sever his connection to it and hand it over to his younger brother. Their murderous intent is plain: surrender the weapon, or die at their hands! Just as Li Yuan hesitates, the Enemy-Funding Rebate System activates! [Li Kun, malice score: 100! Enemy funding returned ten thousandfold!] Li Yuan immediately gives up the epic-grade soul weapon and receives the mythic-grade Xuanyuan Sword! His brat of a younger brother and his awful adoptive parents are now nothing but tools for generating rewards! He gives away a damaged combat technique and gets a perfect one in return... Li Yuan’s power grows without him even noticing, and his resources are inexhaustible. Meanwhile, his adoptive family is getting utterly wrecked by him.
A spiritual novel, the main character of parents' preference has been wonderful step by step from beginning to end. Like to recommend.
