The wind blows the umbrella and draws lots.

You should have had such an experience. You can't control the power of being scared by the wind or the wind hitting the umbrella.

Another thing is that when invisible power is displayed, you will be afraid of what you can feel.

I guess you've had such a shadow, and you were scared by the wind.

In fact, the wind is fine, and you can feel it. Although it is fast, it will not pose a threat to your safety at once.
