Even Ji Rongxinyue couldn't say this time - I'll do it!
Because the reason Ji Xinghe couldn't join the battle was because of her. This also meant that the 'culprit' that might lead the Independent Group to a devastating defeat after a pyrrhic victory was also her.
To allow Ji Rongxinyue to smoothly showcase 'Controlling Mecha With Qi' + 'Mecha Avatar Technique' and complete the most crucial part of a transaction regarding a complete Imperial Transition Base. That is, to make the King of the East believe that Ji Xinghe had mastered the inherited abilities, even making the Martial Emperor believe it.
The only mecha Ji Xinghe possesses, the Star Moon Mecha, would be handed over to Star Moon for the upcoming battle.
Of course, to Qin Tong, Harris, Liu Mian, and others who didn't know about Star Moon's existence, it looked like Ji Xinghe was handing the Star Moon Mecha over to Ji Rongxinyue.
So this blame, Ji Rongxinyue had to take it.
