Investment Rebate: the Enemy at the Beginning Is My Teacher's Wife

(Fantasy, cool writing, system, conspiracy, sect, decisive killing, pretending to be a pig and eating the tiger, shady, behind the scenes, dark flow) Just after time travel, his master was sucked dry by the female devil. Li Changan was forced to take over a rotten sect at his master's funeral. A first-grade useless golden elixir, the elders are rebellious, and the disciples are alienated. How can I be the master of this sect? Fortunately, I am bound to the DaDao investment rebate system, so I can only get rebates on investment? No, no, no luck simulation, swallowing other systems to get upgrades, everything... No resources? The Cangyun Sect is all my resources. I packaged up the unjudgemental sect disciples and the judgmental elders and "invested" them in the Hehuan Sect! The Daughter of Luck breaks off the engagement at the beginning? A betrothal gift that returns investment! Will the disciple become a stepping stone for the girl of destiny? Investment changes your life! Collaborating with the devil? Until Li Changan beheaded the leader of the Hehuan Sect with a sword, the Cangyun Sect began to gradually rise in the Shenyun Continent.
