No matter how advanced the airplane, there is a limit to the height it can reach in the sky. This limit isn't about whether the aircraft can continue flying upwards, but about the engine's resistance to cold temperatures!
Some finely crafted airplanes have extremely stringent requirements for low temperatures to ensure they can fly normally under the cold conditions at high altitudes.
Ordinary planes fall short in this aspect. At a certain height, the extremely low temperatures at high altitudes can cause the engine to seize and freeze, leading to the plane plummeting from the sky!
Aware of this, Lu Yu is now pushing the Cold Crow upwards, without any weapons equipped.
This approach is currently Lu Yu's best method to evade the Controller!
Without weapons, his airplane cannot fend off the pursuit from the plane behind him, which also carries superpower users of the Controller's level.
