You either can retire today and you keep your current wage or you keep working and get paid $500k per year.
So you have two choices, you retire straight away, you don’t have to work a single day anymore for the rest of your life, you get to keep your wage as it is now, it will get adjusted yearly based on inflation.
You are absolutely not allowed to do any work on the side for extra money, you get your wage and that’s it. You are allowed to invest it in the stock market or crypto and try to make extra money that way.
Your other option is to keep working, you will get paid $500k per year but you have to work until retirement age, if you don’t you have to pay back all the money you made. It’s just a normal 40 hour work week with 20 days off per year. You can take extra days off but for every extra day you want to take off you pay $10k back from the $500k. You can at most buy 20 extra vacation days per year.
Personally i would go for option one, $500k per year surely sounds nice but i have an ok salary and would take not working anymore for the rest of my life in a heartbeat.
