Perhaps it was because this bank located on the African continent was influenced by the arrogance of European colonists that it clearly looked down on the IQ of the locals. As a result, the bank system's security was perfunctory and just barely better than nothing at all.
Gu Nianzhi and Zhao Liangze had planned to act together and concentrate their superior forces to attack one port together. By doing this, they could achieve their goals within a fixed time.
However, they did not even have a chance to work together. Gu Nianzhi quickly tried on her own and found that the port was only protected by a very simple password consisting of four random letters.
After some trial and error, she realized that the password composition here was relatively backward. It could only be composed of letters, but numbers and other arbitrary symbols could not be used.
The total possible combinations of four random letters would be 26*26*26*26, a total of 456,976 combinations.
