(It's canon.
Zhang Qilling escaped the attackers of his clan,leaving.Before he escaped,his father told him to find his soulmate and protect him from danger.He said that Zhang Qilling will get a feeling,so he will naturally know his soulmate intuitively.
One night,he saw a teen somewhere between 17-19.The boy had green eyes and a flute.Zhang Qilling observed him for a while before eventually leaving,not caring about him.
The second time Zhang Qilling met him,some guy named Wu Sanxing decided to take him with them on the escapade, that's why Zhang Qilling is with them now.)
(note: Zhang Qilling is no normal human.He is immortal.He has excellent hearing and running speed.He posseses the power of the black Qilling(the ancient dragon.),which he inherited from the Zhang clan.He is emotionless and doesn't talk.No,he isn't mute,the bitch just doesn't feel like talking to unnecessary people.So,he just rarely nods or shakes his head.He also has monthly amnesia,which is why he doesn't care about anything,because he will forget anyway.Whenever he is in a tomb,he finds familiarity in some things and realizes he's once been there,but it's only the feeling.He mostly ignores people and just goes wherever he wants to.
Wu Xie is not a normal human too.He posseses the power of the green Jade.He has a flute with him at all times.When he plays the flute,his eyes turn green and he channels his energy with the flute sounds,leading others to the right path.
He and his father live alone.Wu Xie gets permission from his father to interact with others,with the condition to not show his power to them,but to keep it a secret.Noone knows about his power,he pretends to be normal.)
Zhang Qilling,Wu Xie,Wu Sanxing and others were in front of the eery abandoned and unsafe structure.They contemplated on how to enter the building carefully and be safe at the same time.
After Wu Sanxing found a way in,they all went in,but Wu Xie remained outside.
(You are Wu Xie.)
