"The Thread of Fate: A Tale of Duty And Destiny "

Without a word, Wei Wuxian reached up and touched the corner of his mouth. A small trickle of blood had formed there, and he swiped it with his fingers. Then, in a movement that sent shivers down Lan Zhan's spine, he reached out and wiped the blood on Lan Zhan's cheek.
Lan Zhan's eyes widened in shock as he felt the warm, sticky liquid on his skin. He knew that this was a mark of ownership, a claim of possession. He was now bound to Wei Wuxian, tied to him by a thread of blood and fate.
Wei Wuxian's eyes gleamed with satisfaction as he stepped back, his chest heaving with exertion. "The war is over," he declared, his voice low and husky.
Lan Zhan's expression remained impassive, but his eyes flashed with a hint of warning. He knew that he was now bound to the patriarch, and that their fates were inextricably linked.

Lan Qiren spoke up, his voice cautious. "Patriarch, perhaps you could enlighten us as to what you desire?"
Wei Wuxian's expression remained cold, his voice unyielding. "I desire the loyalty of one of your clans' most powerful member. I desire the services of a cultivator who will swear fealty to me and serve me for all eternity. And I desire..... Second young master of Gusu Lan,Lan Wangji".
