The next morning, there was a long line up in front of the Sixth Street Bank.
Under the supervision of NAC soldiers, people handed in their crystals and changed them into papers with a special identification code. Some even walked out empty handed.
Is the NAC government robbing people?
Clearly not. Due to a culture that praised power, all the survivors possessed guns. And from people rushing in with an expression afraid that the bank wouldn't accept their crystals, they clearly wanted to be inside. And the NAC soldiers that looked threatening were ensuring order in the line.
As to the reason, it had to do with a newly implemented policy.
To change the current chaotic pricing environment on the Sixth Street market, the NAC government used the Sixth Street bank to introduce a new currency known as "credit point", credit in short. It was not guaranteed by any precious metal. Instead, it was guaranteed by NAC's credit.
