Three years ago, Lin Xuan's direct disciple Nangong Yaoyue recruited for Chi Yao Heavenly Palace. Nangong Yaoyue resolutely rebelled against the sect. When Lin Xuan learned about this during the breakthrough process, he almost went crazy. His meridians were backlashed, he was seriously injured, and his cultivation level regressed. In the past three years, Xingyun has been in a decadent state of recuperation. As a result, Xingyun has plummeted, from a mountain with a hundred thousand people to only three or five people left in the end. Three years later, at the Qingyang Sword Sect's apprenticeship ceremony, not only did no one come to submit, but Lin Xuan's favored disciple Yang Hao betrayed him again. Lin Xuan awakened to the most powerful investment system, as long as he invests in his disciples, he can get rebates.
