@Isaiah Cockerham His earned EXP gets distributed between all his summons. Thats why he need so much exp. That's the only logical explanation.

@KDY13 no it doesn't. He earns 1% xp per monster killed. He explains it in the beginning of the manhua. The more he levels up the more summons he's able to call upon and the stronger they are.
