Myriad Worlds: Starting with The Return of the Condor Heroes, I Become Immortal!

After transmigrating into The Return of the Condor Heroes, Li Qingyu obtained the “Myriad Heavens Fortune System.” Good news: I transmigrated, and I have a System. Even better news: The cultivation techniques this System rewards me with are really strange... “Ding! Congratulations, Host, for successfully changing the plot where Xiaolongnü is defiled. You have been awarded the god-tier movement technique, Star God Shattered Shadow!” “Ding! Congratulations, Host. Your favorability with Xiaolongnü has reached 30. You have been awarded the god-tier cultivation manual, Ice Phoenix God-Sealing Canon!” Li Qingyu: “...”! Wait, why are the cultivation manuals in this martial arts world I transmigrated into all from fantasy worlds? (This is something the author wrote for himself while completely indulging in his own fantasies. There will definitely be a harem. Put your brain down before reading!)
