Just splash water on the mirror after opening the game.

The first step, after we open the game, we can ask the crew to shout three times in front of this mirror.

In the second step, we can find that when the lights are dimmed, there will be more blood and the crew will be killed.

The third step, we continue to shout three times, and then we can see the appearance.

The two basic factors of summoning are the mirror in the darkroom and the exact number of times to repeat her name. One said that bloody Mary would only come on certain days, and the other said that she would splash water on the mirror, rub her eyes or hold a knife.

Another version says that as long as you go to the mirror in the dark, bloody Mary will find you whether she screams or not. When it's time to call her, no one will appear, but the water in the bathtub will turn into blood, or see the wounds that don't exist on yourself, or foresee the future. Some ceremonies also include lighting candles, circling in place or holding them in your hands. Because lighted candles are always associated with magic. Spinning around in place is like casting an ancient spell, and it also makes you lose your way.
