Dragonification

It wasn't just Zheng Xue herself because even Bai Long who felt the same way clenched his chest as both of their hearts were being imprinted with the other one's mark. 

Once done, Bai Long who was covered in sweat collapsed on the floor as the relief of the pain disappearing filled him. 

Similarly, while Zheng Xue was doing the same thing Bai Long tested the Pet Contract to absorb her inside him. 

Unexpectedly, inside him didn't mean practically inside him. 

Rather, Zheng Xue was absorbed by the black coloured dragon tattoo which had formed on Bai Long's back when the pet contract was made. 

Along with this, the burning pain both Bai Long and Zheng Xue were feeling disappeared and rather a refreshing cold sensation appeared inside their bodies and allowed them to forget about the near traumatizing experience. 

"So weird. In this state it almost feels as if I'm not a physical existence at all."

"Really? I don't feel any different at all."
