Sam didn't resist.
He just gave up the black smoke. He compressed it all into a small container and gave it to Trike that evening. Trike looked at the small transparent and crystalline container and chuckled.
"You have a solution for everything, don't you?"
Sam just shrugged. The container is attached with an energy resource that constantly provides death energy to it. It is a bit crude compared to Sam's other inventions, because he just filled up a space jade with the liquefied death energy and attached it to a mechanism that extracts the liquid and covert it into absorbable energy.
The only thing that Trike would get to see is that the energy is in liquid form.
He wouldn't know how to achieve it and certainly wouldn't be able to reverse engineer it. Sam's secrets are safe. He even felt a bit embarrassed getting praised for this. It is that crude in his opinion.
"Tomorrow is my last negotiation and I will be leaving."
