As soon as Rathnaar formed the soul-pact with Kahn, he immediately tried to take control over the latter's body and revealed the truth about that being his main intention since the very beginning.
[System… do it!] ordered Kahn.
Soon, Kahn's body arched down and he took a deep breath.
"You really need to stop looking down on others if you want to be in charge." spoke the real Kahn this time.
[What the hell is this?!] shouted Rathnaar in his mind.
At this moment… Rathnaar's soul form was put in a different space as if some sort of jail was created just for him.
"Can I destroy his soul?" asked Kahn.
[No. The subject's soul form is currently too strong for the host to destroy.
The host will need to at least become a 9th stage saint to completely overpower and absorb or eradicate it.] replied the system.
"I see. So I'm stuck with this old geezer for some time." spoke Kahn.
