After I Accidentally Tied a Marriage Thread to My Unfeeling Dao Senior Brother

[Steadfast, honest heroine x deceptively sweet, dark, scheming hero] After being reborn, Xue Zheng, an honest cultivator from humble beginnings, was given a chance to change her fate: She could copy the wealth and luck of heaven's favored prodigies. It wouldn't harm anyone else, but she would have to pay an unknown price in the future. Xue Zheng agreed on the spot. She had nothing, so there was nothing to lose. Everything went smoothly. The sect was full of talented people, the Sixth Dragon Prince was fabulously wealthy, and Senior Brother Mo from the Enforcement Hall was blessed with incredible luck... But none of them could compare to Yao Qingchen, who had ascended in broad daylight in her previous life while cultivating the ruthless path. Xue Zheng carefully and happily copied them all. She copied Yao Qingchen the most, since his powers worked best. When Xue Zheng's mixed spiritual roots were purified into a single spiritual root, when she went from tripping on flat ground to picking up spirit stones wherever she went, and when she could afford to change her sword tassel whenever she wanted... Things started to go wrong. The arrogant Sixth Dragon Prince blushed as he demanded to know why his heart fluttered whenever he saw her. Solemn and serious Senior Brother Mo brought her malt candy and invited her to watch the stars. When Xue Zheng happened to meet Yao Qingchen, the person whose luck she had copied the most, the white-robed young man had a red mark between his brows and looked like an immortal banished from heaven. He smiled gently and called her Junior Sister, just as he always had. That is, if you ignored the illusion beside him, which looked and sounded exactly like him. Yao Qingchen calmly reassured Xue Zheng. "Don't be afraid, Junior Sister. That is merely my inner demon, born entirely from my desire for you." Xue Zheng saw countless red threads of fate winding between herself and Yao Qingchen, covering everything in sight. At that moment, she understood the price. It turned out that every time she copied someone's luck, another red thread of fate tied her to them. But why were there so many threads between her and Yao Qingchen?! Xue Zheng didn't know that... When no one else was around, the Yao Qingchen who seemed serene and dignified to everyone else would repeatedly savor the moments he had spent with her. He had raised those red threads with his own hands. Xue Zheng was an honest woman from a village. She didn't know how to deal with this. Yao Qingchen did. Yao Qingchen said, "There are too many red threads, and I can barely suppress my inner demon. I need your help." Xue Zheng: "Mm-hmm." He also said, "Some things are more urgent than others. You and I are bound most closely. Don't look at anyone else. Look only at me." Xue Zheng: "Mm-hmm." Then he said, "Ah Zheng and I are destined to be together. Would you be my cultivation partner? My primordial yang should help your cultivation more than anyone else's." Xue Zheng: "Mm... huh?!" Later, as Xue Zheng's cultivation advanced by leaps and bounds, she, a body cultivator, began to feel physically exhausted... Yao Qingchen had always known that the red threads of fate couldn't bind him, but Xue Zheng could. P.S. The romance is very intense. Theme: Love.
