The sentry in charge of security on the city wall spotted a black dot descending from the sky in the distance.
"Is that some kind of mutated bird?"
The seasoned veteran squinted in confusion, "Ordinary birds don't grow that big, do they?"
This made the rookie stiffen with fear. "Could it be… a new bug variant?!"
"Doesn't look like it..." The veteran shook his head after using a telescope to observe the metallic glint on the surface of the object. "Not sure what it is. Never seen anything like it before. Better prepare for anti-aircraft security."
Once the anti-aircraft cannons near the city wall were fully prepared, the visitor in the sky slowed its approach upon reaching a certain distance from the city. It stopped flying and landed on the ground, advancing toward the city in a deliberate and non-threatening manner.
A massive blue-and-white mecha strode slowly across the ground, causing the earth to tremble faintly.
The sentries on the wall became instantly excited.
