The Ancestor Growth System Forced Me to Practice to the Peak

Li Yun was an ordinary migrant worker in his last life and lived an ordinary life. Until one day, a strange voice sounded in his mind: Congratulations on binding the Ancestor Growth System, please go to the Xuanling World and grow to the top of the world within the specified time, otherwise the master will be punished by the system! While Li Yun was still in confusion, he had come to a whole new world. And Li Yun will also be forced to become the pinnacle existence in this world!
