Seeing the black-haired young man use his hand as a knife, piercing through Lin Chongyun's chest, everyone's expressions changed.
"Envoy Lin!" Wu Jianghao exclaimed in shock, about to rush forward to help.
However, the situation quickly changed again.
A large number of silver patterns suddenly lit up on Lin Chongyun's body. The pierced body turned into a mass of thunder sludge wrapping around the black-haired young man.
The black-haired young man was bound by the thunder sludge, unable to move for a moment, his eyes rapidly scanning his surroundings.
And in the next moment, the ground burst with thunder light, roaring silver thunder tore through the ground and shot upwards from beneath the black-haired young man's feet!
The crowd looked up to see Lin Chongyun holding a thunder sword!
Not far away, Su Yuan nodded silently.
