If you put a pig-killing knife in front of a dog who has suffered a lot, the dog will be afraid.
How big is a knife if you put it under your feet? If it's a palm-sized knife,
It produces a small amount of brake gas, which is not enough to affect people who sleep.
If it is more than a knife, the Sha Qi will affect people.
When people are awake, the suffocation of this knife won't make people feel anything, but if people
When you are asleep, this Sha Qi will work on people. To put it bluntly, it is in the human soul.
Also, if people know that there is a knife under their feet, they will be more afraid, not because the Sha Qi of the knife has increased.
It is people's conscious fear, that is, fear in the depths of the soul, and fear of hurting people's bodies.
Which is its host.
People are no different from the dead when they sleep. People's consciousness or soul can come and go freely.
The body, because it is Yin Qi, can feel the ShaQi of the knife.
