A person who makes a living by "putting a price on life" ultimately refuses to put a price on life.
Lu Chen's profession is an insurance adjuster - after the accident, he calculates the losses and determines the compensation. He had seen too many calculations about "how much a life is worth" and therefore quit his job as a doctor after a wrong triage.
Then he falls into a world where everything literally comes with a price tag.
In the corridor, you have to mortgage yourself every time you become stronger; what the system recycles is not gold coins, but your memories, emotions and perceptions. The entire world is built on one cold logic: everything has a price.
So what he wants to do in the end is not to become strong enough to defeat Corridor - but to prove that there is one thing that is priceless, thus causing this logic to collapse from within.
