Sneaking in with the Wind!

Guo Chunfeng was caught in a hazy mist, unable to free himself for a long time.

Thankfully, the well-trained Secret Sword Agents were much more effective than he had anticipated. After only an hour and a half, they had already produced a satisfactory answer.

Guo Chunfeng was quite right. In the cyber era, few people bought tickets with cash. In the past two days, only 129 tickets from North Tranquility City to the capital city had been bought with cash in the ticket office.

All 129 passengers had been contacted immediately. Three of them were out of reach, but two of them replied in confusion that they were still in North Tranquility City and never purchased tickets to the capital city.

After investigation, the two citizens of North Tranquility City went to the same bank two days ago at about the same time.

What was odd that both of their ID cards had gone missing.
