Chapter 257: Sneak Attack on the Mechanical Device!

Black and gray smoke quickly covered the sky. The Black Dragon hovering in the air patiently waited for the smoke to disperse.

Not far from where the mechanical device was hit, the White Dragon also saw the thick smoke.

If the mechanical device was really destroyed by the Black Dragon's Dragon Breath, the White Dragon would find an opportunity to test the destructive power of the mechanical device.

This made the White Dragon feel very impatient. It wanted to complete the mission as soon as possible, then return to the castle to enjoy the wonderful food. The food was specially prepared by Mike for the dragons.

Just as the White Dragon was thinking about all the wonderful food back in the castle...

Boom!

A deafening explosion could be heard.

"What's going on? Why is there another explosion?!"

"Could it be that the mechanical device had a series of explosions after being attacked?!"
