"It must be those light bullets Kerr Cowell was shooting into the air!"
Just then—
"BOOM!!!"
A massive explosion echoed above the Mechanical Race City!!
Though they can't see it, the booming sound it made when it collided with the Energy Dome told them that the intensity of the cannon shell was certainly not weak!
"Huh!"
The old man, having experienced many things, quickly calmed down and loudly ordered, "From now on, everyone in charge of refilling Energy Blocks for the Energy Dome must stay still."
"Since you can't see the percentage of remaining energy in the Energy Dome, from now on, you must refill it with energy all the time!"
Originally, they could see the percentage of remaining energy in the Energy Dome. When the percentage reached zero, the Energy Dome would shatter for sure. But the remaining energy percentage was shown on the screen, and they couldn't see the screen at all as it was completely dark.
