S4 Why is mercury blown by the spiritual wind?

If there is mercury in Teamfight Tactics, it will not be blown by the spiritual wind. Of course, if the opponent is a bright spiritual wind, it will ignore your mercury and blow you up directly.

The specific gravity of mercury is not much greater than that of metals. No wind can blow. Spiritual wind does not exist. What spiritual wind is there in the world? The so-called spiritual wind is just a kind of nonsense made by superstitious people.
