Tiger
Even with such a small amount of Focus Qi left, Ryu was a true monster.
How could the rabble know that what Leonel was best at was maximizing his Focus Qi?
His Internal Matrix was like a program in his own mind, streamlining his thought processes and making his execution of his thoughts far more efficient.
These ants weren't worthy of making him use more than the Focus Qi he had. In fact, as he battled, he became more valiant because his Focus Qi was actually slowly replenishing.
As his mind became sharper, so too did his body as his Embryonic Qi continued to work.
Also, it wasn't as though the Fey Sovereign was useless.
Because of treaties, he couldn't take personal action. It was clear that the Fiends had been willing to break these rules because of Ryu's existence.
However, that was the privilege of the strong, while the weak could only bow their heads.
