Su Yu laughed, then with a wave of his hand, tossed the "Energy Coin" back.
Once the Energy Coin touched the hundred-meter diameter Energy Crystal, it immediately fused back into it.
Then, he spoke again, commanding the Mechanical City: "Try it now."
Upon hearing these words, the Mechanical City excitedly responded, "Yes, Master!"
Immediately, the entire Mechanical City started to shake.
Underneath the base of the Mechanical City, huge fissures quickly opened up.
Previously, when the Mechanical City "fed," it would open these fissures to grind and devour various materials with a multitude of engineering tools inside.
But this time, after opening the fissures, what appeared was not drill bits or grinding knives.
Instead, there were thick tubular objects.
Once these tubular objects extended from the fissures and slight adjustments were made to their direction, they quickly began to eject scorching supersonic jets.
