Can natural disasters be predicted in Romance of the Three Kingdoms 11?

1. Cities with generals who know Feng Shui will not suffer from disasters (although the description of Feng Shui is not easy, in practice, generals with Feng Shui are almost 100 immune to disasters)

2. Cities with low public security are prone to disasters and are easily infected by disasters. Cities with low security will lose public security every day. Cities with low public security and disasters will lose some corresponding buildings

Take the locust plague as an example. 100 public security If a city is hit by a locust plague, it will lose 5-10 security points every round (10 days). If you do not patrol and the security drops to a dangerous level, the farmland in the city will automatically explode and the duration of the locust plague will be very long
