Back in 1974, I awakened to the Shenhao System

Description

Du Chuan traveled through time.
Good news: It comes with the Shenhao system, and the system will give away one million yuan every month.
Bad news: Back in 1974, there was a shortage of supplies, a planned economy, everything needed a ticket, and there was no way to get one million yuan to appear in his hands reasonably and legally.
…………
"The Monopoly system is starting..."
"The launch is successful. One million yuan will be distributed to the host every month. It is reasonable and legal...reasonable?...legal?"
"It is detected that the host wants to let the system host the funds released every month."
"The system is restarting..."
"Funds in custody..."
……………
Five years later, reform and opening up are about to begin, and Du Chuan is preparing to welcome his wonderful life as a multimillionaire.
But when he saw a series of asset catalogs given by the system, he was stunned.
It seems that I am not only a multi-millionaire, but also a billionaire!
After five years of fund custody, the system seems to have done great things!
