" So I have a proposal. This is a contract that bind two persons to complete their end of the deal and if anyone tries to not back out of the deal, it will cause the person's heart to explode and that person will die." Kevin had not just randomly made things up, there were similar type of contracts available in this world. 

So, he planned to use this to his advantage to fool them.

.

.

" So the deal is that I will give you guys the antidote without harming you in any way while you guys will give me all your money and allow me escape." 

Kevin had spoken very carefully so that they would agree to the contract. 

Obviously whatever kevin was telling them was a lie as even he couldn't change the contents of the Servant contract and since the scroll was written in an ancient language, no one could tell what was written in it.

.

Kevin knew that making Emily agree to this contract was not a big challenge. As someone who was always sheltered since birth, Emily hadn't seen any bloodshed in her life. Kevin just needed to kill the guards in front of her and make her believe that no one was coming to save her. The lonely and terrified Emily would do whatever he wanted her to do.

But the challenge was to convince Ron to agree to the contract. Kevin could now easily kill Ron but he knew making Ron his servant would be more beneficial right now.

That's why he allowed Ron to believe that help was on its way and provided such lousy deal to make Ron think that he was just an idiot.

.

And he succeeded. 

.

Right now Ron was laughing inside while thinking. 

' Hahaha, what an idiot.  So what if I can't kill you. This contract doesn't block other members of the Clayton family to kill you. I have already sent them a message and within half a day they will arrive here. You wouldn't even be able to leave the forest before they find you and then kill you.

Hahaha, truly the world is full of idiots.'

Kevin had spent the last 4 days to understand what type of person Ron was and found out that he was the type which was the most easy to fool.

Ron was the arrogant type who would think that no one was better that than him and this set Kevin's victory in stone.

.

.

" However if you don't agree, I would have to kill you all. So if you agree, move your eyes up and down." Hearing Kevin's threat Emily hurriedly moved her eyes up and down repeatedly while Ron also did the same while laughing inwardly. 

Seeing this kevin knew that Ron had taken the bait and he moved to crouch beside both of them.

" Since you can't move your bodies, I will make a little cut on your finger to drop a small amount of blood on the contract and you must think ' I agree' for the contract to be completed. After you have done that, I will also do the same. Do you understand?" Kevin said and looked at both Emily and Ron, only to see them moving their eyes up and down again.

 Kevin nodded and then opened both servant contract, taking a knife out his spatial ring he made a small cut on both of their fingers. Seeing the blood falling on the contract Emily immediately thought 'I agree' inside her mind.

As soon as she accepted, Kevin got the system message. 

*[ Emily Clayton has been bounded by the servant contract and would remain host's servant until her death or until the host free her.]*

After reading the message kevin turned to look at the terrified Emily and smiled sweetly as he said

" Thank you Emily, you really made it easy for both of us, unlike a certain someone." Saying that he immediately stabbed the knife in Ron's right thigh.

.

.

Ron wanted to mess with kevin a bit and wanted to waste his time but what he didn't expect was Kevin ruthlessly stabbing him with a knife. 

Muffled pained cries came out of Ron's closed mouth, he wanted to move his body but couldn't.

Looking at his trembling eyes, kevin twisted the knife and said while still smiling sweetly. 

" Why don't we try this again and next time it will not be your thigh but your heart. Understand? "

.

.

Ron wanted to curse at Kevin but seeing the creepy smile on Kevin's face, he decided not to try his luck and moved his eyes up and down to show his acceptance .

Kevin pulled the knife from Ron's thigh, making him groan in pain again. He then splattered the blood from the knife onto the servant contract. 

Seeing kevin splattered his blood,  Ron immediately thought ' I agree ' inside his head, afraid to get his heart pierced with a knife.

*[ Ron Clayton has been bounded by the servant contract and would remain host's servant until his death or until the host free him.]*

As soon as kevin saw the system message, he knew that he had succeeded and started laughing loudly.
