Good-For-Nothing? I Became the Supreme King in Mainland China by Earning Rebates from My Apprenticeships

As a child of a declining family in the world of immortality, Lin Zixuan finally broke through the foundation and became the ancestor of the family, but found that his qualifications were exhausted and his path was cut off. Unexpectedly, the enemy in the past climbed up the high branches of the Immortal Sect and came to the door with the power of the Ten Thousand Swords Sect, forcing him to abandon his cultivation and kneel down to apologize. The Lin family's foundation was destroyed in one fell swoop. In a desperate situation, the portable jade pendant that had been dormant for a hundred years suddenly awakened - [Disciple Rebate System], activated successfully! "Give the apprentice a body tempering pill, and the system will return a bottle of foundation-building spiritual fluid." "Teach the apprentice an introductory skill and return it to the high-level inheritance." From then on, there was no mediocrity in his eyes. The five spiritual roots are useless? That is uncut jade! Kendo fanatic? It is clearly a pure Taoist heart! When the Demon Lord and his coalition forces came to the border, he vowed to erase the last traces of the Lin family. The door of that run-down family, which had been underestimated by the entire world of cultivation for hundreds of years, slowly opened. The sweeper put down his broom and raised his sword to the sky. He was once a contemporary swordsman famous overseas. The cook wiped her hands, and the fragrance of alchemy filled the world. She was actually a talented alchemy girl from a hidden wealthy family. A handyman carrying water, a mute girl collecting medicine, a child studying... Figures that were once regarded as "waste materials" walked out calmly, and for a while, the sky was covered with immortal power like a prison. The coalition forces were horrified, and the Demon Lord was even more trembling: "Who... Are you?!" Everyone looked back at the figure in green shirt who was always calm behind them. Thousands of immortals bowed their waists in unison, and their voices shook the sky: "Master, please give me the order!" Lin Zixuan rolled his sleeves and chuckled: "I don't have much ability, I just know how to raise a few apprentices."
