If his spirit power was depleted, Fox would instantly lose all control of underlings, and they would rely on their instinct to act after a short pause.
They might turn their heads to attack the dark elf or might resist the skeletons and the ghosts.
All of these were unknown. The only certain thing was that the battlefield would lose control and all the previous efforts would be in vain.
"Master, I'm sorry to tell you the bad news. My spirit power is about to dry up. I may not be able to continue to control 25 servants."
Fox never tried to control the slaves to fight for a long time.
This made him extremely uncomfortable and on the verge of collapse. If he hadn't been accepting the power from Francis all the time, Fox suspected that he would have dried up spirit power long ago.
"Isn't the spirit power enough?"
Francis kept in touch with Fox. After knowing his situation, he thought for a long time.
