Last time Han Fei tried to pull the girl out from the Monster's body, but the Monster's body collapsed halfway through.
He had been unable to understand why, but now he had figured out the reason.
The girl's body and the bodies of seven victims were intertwined with each other. To pull the girl out of the Monster's body without making the Monster disappear, he had to find "flesh" to replace the girl and fill the Monster's body!
Ordinary "flesh" wouldn't work, only the original remains of the victims could completely merge with it.
Holding the girl in one arm, Han Fei continuously placed the Human-body Puzzle fragments he found into the gaping wound in the Monster's chest as he dragged the girl out.
The Puzzle fragments found by Han Fei were imbued with some of the victims' emotions and humanity. The originally desperate and pained Monster, after merging with the Human-body Puzzle, gradually became less frenzied.
"Hold on to me! Don't let go at any cost!"
