I've Already Taken Down the Master, and Now I'm Coming to the Strategy System?

After being dragged to death by his evil girlfriend, Xu Xingzhi accidentally traveled through the world of immortality, but he never expected that his evil girlfriend also traveled through time! What's even more terrible is that she actually became a saint of the immortal sect. For a time, she was so famous and powerful that she could cross the water with her own life... In order to save his life, he had to start attacking the beautiful master who brought him back to the Immortal Sect, but unexpectedly, it turned out that the cold and lonely master was actually a yandere master who wanted to control himself! What makes Gu Yan tremble is that the love system actually came at this time, and the first target it issued was his innocent senior sister... In other words... I want to capture the senior sister under the eyes of the yandere master, right? ? … Xu Xingzhi looked at the missions issued by the system one after another, and became more and more frightened. The Buddhas, Bodhisattvas, demon witches, and dragon princesses were all more outrageous than the last! Things seem to be going in an uncontrollable direction! After completing each task, he looked at the fairies with dangerous smiles and showed an awkward yet polite smile: "Listen to my explanation!" "This is just a task under the system!"
