When Wei Ying destroys the Stygian Tiger Seal he expected his corpses to turn on him as the boundless resentful energy from the seal ran rampant in his body. However it didn't, instead he watched as the resentful energy swirled around his body until he couldn't see nor move. Was he dying? 'Are you willing?' A voice echoed within Wei Ying's head. 'Willing to what?' Wei Ying thought confused. 'To pay the price to go back and change everything.' The voice echoed and Wei Ying felt a chill go down his spine. 'Whatever the price, I am willing to pay.' Wei Ying thought with unwavering conviction. Several different giggles echoed around him, 'then, we shall lend you a hand in your endeavours.' _________ This is a mix of au's, time travel, Wen! Wei Ying and vampire Wei Ying.
