"Daniya, let's make this clear first. If we encounter any danger, I need you to completely trust me and listen to my commands. There must be no doubt or hesitation ... Can you trust me?"
Lin Yi really treated Daniya as his partner now-he'd open up the Jade space to her if things got too dangerous!
Because of Daniya's identity as a Dark Beast, she could be kept in the Jade space directly. This way, Daniya naturally didn't have to face the dangers of the outside world, and if Lin Yi ran away alone, he had more tricks up his sleeve and a higher chance!
For example, he could store his physical body back into the Jade space and find a temporary body for his primordial spirit. It would be best if it was a soldier of the darkness demon beast Army. This way, he could secretly leave the hundred tempered demon territory.
