Above the clouds, a uniquely designed airplane took off from the airport at the edge of Ideal City, heading toward River Valley Province.
It had a total of four engines distributed symmetrically on the four corners of its body, with two at the front and two at the back, emitting light blue plasma streams behind them.
This transport aircraft was a civilian-modified version of the "Tiger Whale" transport plane, with an elongated body and increased cargo capacity, plus an additional pair of plasma engines.
Since it was civilian, the aggressive name "Tiger Whale" had been changed to the relatively gentler "Blue Whale."
From the outside, the plane looked like an advanced version of a four-prop tilt-rotor aircraft, where traditional propellers were replaced with lighter, more stable, and less airflow-affected plasma engines.
