Soul-Piercing Saint, I Was Tricked by the Black-Hearted System to the Point of Vomiting Blood

[Anti-routine + time travel + multiple female protagonists + fast pace + intensive excitement + pendant system + one soul and two bodies + constant reversals + a huge world view! ] The story begins: "Graduate student? No more taking the exam! Go play time travel!" "Hmm O. O? It's broken! I really traveled through time!" Xu Qingfeng traveled into the body of a woman named Yao tide and awakened a deceptive clone system! Clone (Xu Qingfeng): "Okay, okay, I am so cheating on you, aren't you? Look at my hard work in cultivation, I will accept you sooner or later!" Real person (Yao tide): "The little clone is so ridiculous, it's really no big or small!" Later... The original deity (with an angry face): "You are a clone, how about you have a sense of responsibility and boundaries as a clone?" Doppelgänger (full of excitement): "I am better than you, whoever is stronger is the real one! Moreover, the system told me that if you can be happy with me, you will be invincible in the world!" Myself: "Ah? That will happen in the future! At least not now! Huh? What are you doing?" And later... Myself: "Xu Qingfeng! I don't care how many hookups you have, but the biggest one can only be me!" Doppelgänger: "Okay, okay, yes, yes, I know, I know!"
