Investment Returns: Starting with funding the enemy, that's my master's wife.

(Fantasy, action-packed, system, sect, ruthless, playing dumb to outsmart others, cunning, behind-the-scenes, dark fantasy) Upon transmigrating, his master's cultivation was drained by a female demon, forcing Li Chang'an to take over a rotten sect at his master's funeral. A useless first-grade Golden Core cultivator, rebellious elders, and disloyal disciples—how could he possibly be a sect leader? Luckily, he was bound to the Great Dao Investment Return System. Only investment returns? No, no, no luck simulation! Absorbing other systems to gain upgrades—it had everything… No resources? The Cangyun Sect was all his resources. He packaged the loyal disciples and the disloyal elders and "invested" them in the Hehuan Sect! A woman of destiny annuls her engagement? Investment returns the betrothal gifts! Disciples become stepping stones for the woman of destiny? Investment changes fate! Colluding with the demonic path? Until Li Chang'an beheaded the Hehuan Sect leader with a single sword strike, the Cangyun Sect began its gradual rise on the Godfall Continent.
