Tiandao Investment Becomes a Saint

Lin Yi, the "trash" from the outer sect, unexpectedly awakened the "Tiandao Investment System". A potential score sheet allowed him to see another possibility in the world of immortality. Invest in Li Qingxuan and get water-based skills; invest in Wuji Sword and get the inheritance of swordsmanship; invest in Zixiao Thunder Girl and get the secret of thunder method. While everyone was still practicing hard, Lin Yi had secretly trained three master-level experts. Who is secretly helping? Who is behind the scenes? Who is the real king of the world of immortality?
