"The Devil is looking for a matchmaker!" Hearing his words, Ma Chunyi couldn't help but gasp. Although it was the first time he had seen the real thing, the name of this thing had already been heard by thunder.

In fact, the compass is not like what is shown on TV, it is all two needles. In fact, it has many classifications, which are divided into double needles, four needles, eight needles, ten needles, twelve needles, twenty-eight needles, thirty-six needles, and seventy-two needles. The corresponding comparisons are the two instruments, the four elephants, the eight trigrams, the heavenly stems, the earthly branches, the stars, the heavenly gangs, and the earthly evils.

But it's not that the more pointers there are, the more powerful they are, it's the difference in efficacy. Some of them are exploring the wind and water, some are chasing yin and catching yang, and there are also auxiliary tools for astrology and divination......

Among them, the most common two-needle compass is the red and black double needle. The red needle is yang and the black needle replaces the yin, and the red needle is generally quenched with cinnabar and boy's eyebrows as a medium to lead to the yang. The black needle is generally smeared with carbon and animal ashes, both of which are yin and thus lead to yin......

Although this kind of two-instrument compass is simple to make, it has many functions, almost all of the above compass functions, no matter which aspect, it can be plugged in......

But there is a saying that there is a lot but not a fine, although he can do anything, but the effect is not particularly good. Just like today's mobile phones, you can take photos and listen to music and other functions. But no matter how high its pixels are, it's impossible to reach the level of a professional camera. No matter how good its sound is, it can't be as good as a professional player!

Than: 1: Ben: Read: Novel 3w.ybdu is like chasing yin and supplementing yang, if only one goal appears, then it's fine...... Because he can quickly discern it, and thus assist the cultivator. However, if two or more targets appear at the same time, the ordinary compass will be chaotic, like a computer in a state of waiting for a virus. Put the cultivator holding the compass in a situation of "blindness......

Even if it is the best of the Liangyi compass, Ma Chunyi, the "second generation of Dao", uses the Tianxing Liangyi Plate. It can only be used to sway and rotate to indicate the strength of the opponent's yin or yang energy, and then judge the distance of the target by the degree of downward direction of the needle, and finally point to the place where the yin and yang qi are most strong, as for the target in other directions, it is powerless! It can be said that it is a universal version of the compass......

The compass is an extremely important tool that acts as the eyes and ears of the cultivator, because not every cultivator can open the path to the underworld. (This path to the underworld is a collective term for the Heavenly Eye, the Wisdom Eye, the Dharma Eye, and the Yin and Yang Eye, which means a way to see things in the underworld.) Even if they are opened, few will last long. is like the current Ma Chunyi, and the consequences of forcibly opening or prolonging the time limit of Tianyan many times will hurt the internal organs, and the heavy one will die!

Even if his master Liu Taizhen reached the cultivation level that could maintain the Heavenly Eye for a long time, he still needed to use a compass to assist. Because the places that can be reached by the naked eye are limited after all, coupled with the influence of special terrain and obstacles, and even some injustices will be cunningly hidden in some objects, so it is even more difficult to have a 100% view......

And this compass is like the radar on a fighter jet. No matter where you hide, as long as you are within the search range of the compass, you can make it hide, just like the controllable range of the two celestial and star disks reaches 500 meters away.

Unless something unexpected happens, just like Gu Qian accidentally entered the TV, because it already belongs to another dimensional space, or the other party's cultivation is extremely high, enough to have the strength to cover up his yin or yang energy......

Therefore, no matter whether a cultivator's cultivation is high or low, the compass is one of the important magic weapons that cannot be replaced!

Since it was so important, and the Liangyi compass could not meet the locking of multiple targets, the later Daomen sages invented two other kinds of compasses, namely the thirty-six-needle compass and the seventy-two-needle compass.

The former is the pursuit of yang energy by the number of Tiangang, and the main use is sacrifice. The latter is in response to the number of earth evils and is only used to probe the yin.

The reason why Ma Chunyi was so surprised was that the production process of this compass was very complicated.

Each of its seventy-two needles is engraved with different talismans to make them their counterparts. Just imagine how difficult it would be to carve an extremely cumbersome talisman on a tiny pointer. Even the top miniature carving masters must have to work hard.

What's more, a certain amount of yang energy must be input when carving the seal, and it cannot be interrupted halfway...... Otherwise, the talisman will not be effective at all!

According to his estimates, the carving of a pointer will take at least half a day, and if there is a slight difference, a pointer will be wasted, which can be said to be a waste of all efforts!

There are a total of seventy-two probe needles in this compass, how long does it take!

Not only that, but after the talisman is engraved. It is also necessary to distinguish the quenching medium by the size of the target yin qi and the amount of quenching medium one by one. Again, this is a vast project......

Because the yin energy emitted by the target can never be the same, even if the cultivation is close. But there will be a difference to a greater or lesser extent. And it is this little difference that creates the compass of these seventy-two needles. And this compass is also named the Earth Demon Finder because of the number of pointers!

It's just that this Yang Lao Er made the Earth Demon Matchmaker into the appearance of a watch, presumably for ease of carrying......

Thinking of this, Ma Chunyi couldn't help but admire Yang Lao Er, how much perseverance it takes to make such a magic weapon! But then again, this product is really idle, since he has so much time for him to squander so much!

At this moment, the pointer on the earth-shattering medium, except for one of them, pointed to Xu Jiang on the side, and the remaining seventy-one were all fan-shaped, pointing to the side and the front. Judging by how it works, that is. There must be at least seventy-one Yin targets approaching them right now!

"How can there be so many!" Ma Chunyi was a little speechless, because he didn't expect that there would be so many injustices here, weren't there only a dozen when he listened to Xu Jiang's narration? How could so many suddenly pop up!

And he couldn't tell the distance between the target and himself, because the detection radius and sensitivity of each compass were different, and only those who used it would know the contents, so he lowered his voice and asked: "Brother Yang, what is the detection radius of your plate?" And how far are we from the goal? ”

Yang Lao Er thought about it for a while before he said with certainty: "I have really tested it before, and the farthest can reach about 300 meters!" Judging by the degree of the pointer downward, it should be about 200 meters! ”
