Online Tycoon: Tips Turn into Cash Rebates

I would like to give myself a five-star review first, haha, to give myself recognition for my hard work in coding. I hope friends who have read it will leave a book review and leave your valuable opinions. When I first wrote the price of the villa to 15.8 Billion, I saw a lot of people criticizing me. After thinking about it, I did not think carefully enough at the time and it was a bit unrealistic. I immediately changed it to 1.58 Billion. I accept criticism and opinions. If you have any good plot developments, you can talk to me.
