What is a dragon ruler? You got it? Can I talk to you?

What the hell is a dragon ruler? You take a wire, bend it at right angles, and then hold one end in your hand. This is a dragon patrol pool. It is said that it can help you find veins, water sources, underground pipelines and even anything buried underground. Well, there are usually two such things. When you use it, your hands are parallel to your chest, and then walk forward. When the front end of this dragon pool passes through your chest, it means that what you are looking for is below. Someone is using it now, and this foreigner is also using it, which shows a problem. This is not our local product, but from the outside. It is a popular divination witchcraft in medieval Europe. It is called divining staff abroad, and its function is similar to that of the ancient geomantic compass in China.

This kind of divination record is said to be very early in 8000 BC. At that time, divination was a Y-shaped branch, and then you held both ends in your hand and walked forward parallel to your chest. The front end is drooping, which means that what you are looking for is below, so finally. There is also a variety of this divinatory pole, which is the L-shaped dragon hunting pool we are seeing now. So before, Europeans used this to look for gold, ore veins, water and oil, and later it spread to us, and it was changed to a very rustic name, called Dragon Hunting Ruler. Then everyone thought that this thing might have been invented by our ancestors, but it didn't come from the outside. So now we say this thing is scientific.

Now the handle and the rotating shaft of the dragon finder are very flexible. If the hand is slightly tilted, it will swing on it. It is said that his principle of finding things relies on fascinating natural induction, that is, human magnetic field. So in short, you just can't make it clear, and there is no scientific reason. As for why people are still using this thing, it can only show that it may have been discovered, or that he found it because a blind cat met a dead mouse. So in short, science has also verified this thing. The accuracy of his search for something is the same as that of a blind guess, but it is also a correct probability. If you use this thing and find it once, you will be surprised.
