To be able to create one's own skill and pass down a portion of their strength to their subordinates, the enemy had to be incredibly powerful.
Even Simon had a vague idea when it came to the level required to achieve something like that. He was mostly unaware of the realm beyond level 800+.
Be that may, what he had to do didn't change. Since such a powerful enemy was lying in ambush in the shadows for him, he just had to rise up to the challenge and get stronger faster than before.
That's what he had been doing up until now and had to continue to do so. Especially now when the fates of all the people dear to him, depended on him.
"If there is one thing that can quickly allow me to increase my strength, then it is the Celestial Oculairs" Simon touched his left eye.
