"Resting In The Middle Of The War"

Gold coins that Jake collected are actually used as a global currency between human and non-human races. 

The non-human race also does business with other non-human races using copper coins, silver and gold coins! 

But Jake...had a different use of these gold coins. 

The young man didn't say anything and just played with his tie before nodding at Ainsley. 

"Okay, that's it for the meeting. Remember, our goal is to survive until the reinforcement arrives. But don't rely on reinforcements. The enemies might have reinforcements too." 

The big bosses' ears perked up at Jake's words. 

"The enemy might have reinforcements too? Isn't that bad? If their reinforcements are better than us, won't we fight a losing war in the end?" 

If they knew that they would lose in the end, they would have searched for someone who could relocate the Inheritance Stone Mine and abandon the island altogether.
