After having a recap of the past because of Rathnaar's sudden query, Kahn realized that he was actually the Apostle of War Deity.
Because blessings and gifts from a Deity are only given to those who gain their approval and are considered as the official representative in the world.
As he just found out that Kravel was considered to be the strongest deity of them all. This made Kahn question his own potential.
Because Kravel was a human just like him and neither was he a chosen hero, had divine abilities or even a blessing from a deity.
And yet, he achieved the feat of reaching the peak saint rank, created the Abyss Empire, kill an Elder Dragon as well as an Archangel who were supposed to be as strong as a Demi-God and finally, he nearly achieve world domination until the Gods themselves had to interfere.
Just like Rathnaar said… all the chosen heroes were a joke compared to someone like Kravel, the War Deity.
