Shane didn't know if there was a profound meaning behind the word 'King' inside the Primordial dimensions.
As such, he could only use his comprehension to figure out the Three headed blazing lion's combat prowess.
However, from the first encounter of his darkness spears, Shane was already able to tell that the lion's blazing flames were searing hot and strong enough to burn through the darkness spear, decreasing its lethality drastically.
The heat around Shane was unbearable and he was smoking profusely.
At the same time, he knew that he would be smoked like tinder if the blazing flames were to envelop him.
That was. if he didn't use any mana in order to protect himself.
With his [Light steps] movement technique and the [Slaughterer's Path] technique fully utilized, Shane had to use his full concentration, in order to circulate mana through his body while releasing some of it to envelop his body.
