"What's going on again?" Officer Zou hurriedly asked.
The subordinate took a deep breath and said, "Officer, those two people took less than five minutes from entering this courtyard to leaving. In other words, they killed fifteen mercenaries in that five-minute period. Besides the initial few shots fired, the remaining mercenaries didn't put up a fight, or didn't even have time to resist and were directly killed by them. Furthermore, these mercenaries were extremely scattered across three floors, ten rooms, and adding the five mercenaries downstairs, all of them were killed within five minutes. In five minutes, these two not only had to kill but also move across ten rooms upstairs and downstairs. Officer, this is beyond human capability!"
