Physical evil: there are buildings under construction nearby. If there is a construction machine (such as a crane) similar to Libra on the top floor of the construction site, it is called Libra when it is seen in front of doors and windows. This kind of evil often appears at the same time as the sound evil.
Impact: far away, the lethality is small, near, it is easy to get hurt or there is something wrong with the eyes.
Solution: put the dragon god or the five emperors' ancient money that has been opened in the evil to solve it.
