Originally worried that the female juvenile Metallic Dragon Yilan would create chaos for the rescue team, Chen Fei simply left it under the 'Life Tree' in the 'Boundary Pearl' Life Space to roam freely. This place is full of novelty, at least much more interesting than being with the rescue team that needs patience to gather intelligence and find opportunities for action.
When the 'Lord of the Sky' invaded the Life Space, following Chen Fei's instructions, Yilan hid in the tree canopy of the 'Life Tree', waiting for an opportunity.
Opportunities always favor those who are prepared (dragons).
The 'Lord of the Sky' and the Sagalis never expected a Metallic Dragon to be hiding in the Life Space, and under the unguarded circumstances, Yilan easily accomplished a coup, secretly replacing several mechanical constructs, creating an opportunity for Chen Fei to break away from the control of the 'Lord of the Sky'.
