His vitality had been fiercely consumed, and even if it was replenished by a Life Potion, it had already become a hidden injury that required a special potion to be compounded before he could cure it.
In addition, the curses he had dispersed also left some hidden wounds. If he didn't heal himself as fast as possible, it would pose great trouble later on.
This was something that had been tested through the shedding of blood from countless mages. After being cursed, whether they sensed the hidden wound or not, they had to treat the injury thoroughly.
But this battle wasn't without benefit. The fierce battle, which caused his mana, vitality, mind, and soul to take damage, had slightly shaken the gate that wouldn't move even if the world ended.
This meant that it should be possible to advance to the Heaven Rank soon. He only needed to quickly find the opportunity to advance. And the best method was to seek a breakthrough in battle.
