After Losing My Memory, I Bound Myself to My Immortal World's Archenemy

To make sure the mission target he had worked so hard to get stayed bound to him, the thing Zong Yu did most was badmouth the Immortal Venerable Nanqi! "Immortal Venerable Nanqi is vicious. The mud around his immortal palace has been stained red with blood." "Immortal Venerable Nanqi is petty, too. He holds onto the tiniest little thing for hundreds of years." "They say Immortal Venerable Nanqi attacks at the slightest provocation. Junior Brother, think carefully!" Zong Yu: There's no way that after all this brainwashing, his junior brother will still get stolen away by the other side! Yan Qin Chao, top of the Immortal Realm's rankings, said, "...Senior Brother, what deep grudge do you have against Immortal Venerable Nanqi?" Zong Yu declared righteously, "He's trying to steal my person (the one I'm bound to). It's a fight to the death!" Yan Qin Chao paused for a moment, then looked deeply at Zong Yu. "Don't worry, Senior Brother. I won't let anyone steal me away." Years later, they returned to the Immortal Realm. Zong Yu's memories came back. He turned around and saw his junior brother, whose swordlight was powerful enough to tear open the sky. That swordlight belonged to Immortal Venerable Nanqi himself. Zong Yu: Holy crap!!! He'd been spreading dirt about the actual person himself? His legs shook. He turned and bolted. Behind him, Immortal Venerable Nanqi, Yan Qin Chao, pursued him with swordlight. Each word landed like a blow: "Senior Brother, why are you running?" * Everyone in the Immortal Realm knew that the first thing Immortal Venerable Nanqi did after returning from his travels was slash apart the immortal residence of his old rival, Immortal Lord Shiyan. But they didn't know that, when no one was around, Immortal Venerable Nanqi leaned down and brushed his thumb across Immortal Lord Shiyan's lips. "Are you trying to take me for a ride and abandon me again? Hmm?" Zong Yu: Who could have guessed that Immortal Lord Shiyan was actually me?!!! P.S. The shou is Immortal Lord Shiyan; he just lost his memories and forgot. P.S. 2. The story begins with both of them suffering from amnesia. Two big shots use alternate identities to fall in love. P.S. 3. The cold sword-wielding venerable gong falls for the second time × a coquettish, sweet-talking, narcissistic immortal lord shou. Theme: Keep striving!
