The Trillionaire System

"I will volunteer myself as a guarantor for the $30 million loan." said by the poor son-in-law. Could you believe David Anderson, the poor son-in-law, volunteered himself as a guarantor for a $30 million loan, despite being despised and treated badly by his wife's family? Ignorantly, he made himself the guarantor for such a crippling loan just because he wanted to prove himself useful to the family. David was locked up at the loan company custody due to their crazy and wild policies. He starved for months, and he was also sent to work at the loan company's construction site with an empty stomach to limit the loan's monthly interest. He was going through hell while still on Earth until an amazing system found him and made him the owner of the whole city. What do you expect as David's comeback?
