"Huh? It won't budge?"
Chu Xin pushed hard, but the lid of the coffin didn't move an inch.
A trace of surprise appeared in the narrow eyes of the Two-headed Fire Dragon, finding it unbelievable that the little demon's strength was so terrifying that she couldn't move the coffin lid.
"Sister, let me help you."
Chu Chen stepped forward and joined Chu Xin in pushing hard.
Despite their faces turning red with the effort, the siblings still couldn't make the lid of the coffin budge at all.
"This is way too heavy."
Chu Xin blinked her big eyes and muttered softly. It was the first time they had encountered something that couldn't be moved by their Divine Power, which made her even more convinced that the Demon Coffin was an extraordinary treasure.
