Moment of Truth

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.
