The black pupils of the corpse demon zeroed upon Leng Yan and the others, and the two black dragons on his shoulders spat out scorching black flames. A tyrannical presence exploded from his body, and he bellowed, revealing his sharp fangs. The corpse gas then concentrated around him.
Leng Yan looked at the corpse demon, slightly frowned, and his body exploded with peak tribulation passing stage strength. In his hand, he held a black seal paper with indecipherable runes scrabbled on it.
He flung the paper in front of him, and it exploded in the air, triggering a powerful pressure. It turned into a chicken egg-sized thunder ball and shot forward, toward the corpse demon's body.
When the thunder ball dispersed, it turned into electricity flowing into the corpse demon's physical body.
