Please Help me with this query

I have a net worth of around ₹22–23 lakh currently, which I earned through three years of my experience in the IT industry. I’m imagining a hypothetical situation where I later earn a large sum (₹4–5 crore) through illegal activities such as drug sales, etc and then get caught. If the police seize my accounts, how can I prove that the ₹22 lakh currently in my bank is legitimately earned through my job and not from illegal activity?

Will they seize my 22-23 lakhs money also?
