Aida Kang ultimately fell for Ji Xinghe's trick.
When the real appears fake, the fake seems real; when the fake appears real, the real seems fake. It truly could not determine whether Ji Xinghe had actually come to the Base No.5 warzone or not.
This question was critical for its decision on whether to join the battle.
The defensive and performance advantages of the Prince Mech allowed it to disregard all of the Federation's precision-strike type firepower weapons.
Even Dragon Continent's East Wind-520, with its speed of fifty Mach, would find it impossible to accurately hit it when it was capable of high-speed maneuvers on the ground.
The only threat to it would be large-scale lethal weapons, the kind that does not distinguish between friend and foe, such as nuclear weapons.
With Ji Xinghe present, the Federation would not use such weapons. Without Ji Xinghe, the Federation could completely accept the losses.
