Ji Xinghe didn't want to be a General, he only wanted the weapons of a Count Level Mecha.
"They should be made of tungsten steel, two of them if they're Count Level. If I let Shen Mu modify them, then Xiazi and all of them could each have a short blade made of tungsten steel. If they're not comfortable with short blades, then we won't modify them, we'll just give them two to start with, and the rest can be delivered later."
During his journey, he remembered his promise to Xiazi and Quezi, a weapon made of tungsten steel for everyone. This would bring a significant boost to the Xinghe Squad's capabilities.
In the Federation, even a Special Level like Jackson only used a Mech Heavy Sword with high frequency oscillation characteristics. The material was better, capable of clashing with weapons made of tungsten steel, but still inferior.
