Chen Ziyang first put his legs together, and then put his compass on the ground, just before his toes together. Then he took out the red rope he was carrying, tied it to the frame of the compass, and at the same time took out the compass of the feng shui master surnamed Du, and after calibrating the pointer on the compass in the same way, Chen Ziyang moved.

"Looking at the mountains and knowing the shape of the dragon, looking for the dragon to put the eye on, the earth master is showing the means, and the feng shui is naturally clear." Every time he said a word, Chen Ziyang took a step in a certain direction. There were twenty words in this mantra, and by the time he had finished shouting it, he had already taken twenty steps. Then Chen Ziyang put his legs together and took the twenty-first step.

Twenty-one is exactly three sevens, and the Maoshan Dao Law is respected by seven, which is the number of the Beidou Tiangang. The set of footwork used by Chen Ziyang was taught to him by the old Taoist, and it is called the three-seven stepwork. There are a total of twenty-one steps to take, and these twenty-one steps are taken in different directions. When the twenty-one steps are completed, the distance between the start and the end is exactly ten meters.

This set of 37 steps is created by Lao Dao for Chen Ziyang, combining Lao Dao's feng shui technique plus the reasoning of hexagrams, combined with Chen Ziyang's leg length and the size of his stride and specially tailored for Chen Ziyang, which was given to him as Chen Ziyang's teacher's gift.

In order to let Chen Ziyang concentrate on practicing this set of footwork, Lao Dao beat Chen Ziyang a lot, and let him keep practicing, until he made sure that every time he used this set of three or seven steps, the foothold was exactly more than ten meters away from the starting point.

At the beginning, Chen Ziyang didn't understand the use of this set of footwork studied by Lao Dao. What's the point of being able to pinpoint a distance of 10 meters? Nowadays, a variety of equipment can be said to be endless, covering a variety of functions, and any tool can be more accurate than this set of footwork.

Therefore, in Chen Ziyang's heart, this set of footwork is basically useless, and it is only left as a gift from his master. However, although he felt that footwork was useless, Chen Ziyang still practiced very hard. After all, this is specially created for himself by his own master.

However, in this dark space without any references, in this place where there is no tape measure or other measuring tools, this set of footwork allows Chen Ziyang to accurately measure the distance of ten meters. Chen Ziyang doesn't know how many times he has practiced this set of footwork, even if he hasn't walked this set of footwork for several years, he will come out at this time without any mistakes.

After placing the second compass in front of his toes, Chen Ziyang squeezed out some blood again, dripped it on the ball, and then waited quietly for a while, until the black water on the ground flowed in another direction, and then Chen Ziyang calibrated the compass in this direction.

Comparing the pointers on the compass, Chen Ziyang took the compass and slowly moved back and forth along the straight line in the direction of the flow of the black water, and at the same time tightened the red line on the first compass until it coincided with the ten paths of Tianxin on the second compass, Chen Ziyang could be sure of one thing.

Now the destination he was going to formed an isosceles triangle with the place where the two compasses were, and the bottom edge of this triangle was exactly ten meters long that he had measured with the three-seven-step method before. And the angle of the two bottom corners of this isosceles triangle can also be known by the parameters on the compass.

After making a simple calculation with a mathematical formula, Chen Ziyang roughly estimated the distance between the destination and here, but because the bottom length of ten meters is too short, and the place he wants to go is really a little far, compared to the distance between himself and the destination, the distance of ten meters is insignificant, so it is very likely that there is a relatively large error in his calculation.

After moving ten meters again in the same way, Chen Ziyang was already twenty meters away from the first compass, in fact, it was not that he didn't want to continue to extend this distance, but he really couldn't do it.

This space is very dark, and he can only see the distance of five or six meters by visual inspection, and Chen Ziyang can't see the first compass before, so he can only use the red rope in his hand to correct it. But the red rope in his hand is only more than 20 meters long, and the current distance of 20 meters is already the limit of what he can lengthen.

This time, the angle on the compass was much more accurate, and after Chen Ziyang calculated again, and combined with the results of the first calculation, he roughly estimated that the destination he was going to was almost a kilometer away from his current position.

If you know the direction and the distance you are going to walk, even if there is a slight deviation on the road, as long as you have covered the distance of this kilometer and carefully searched nearby, you will basically not miss the destination you are going to.

At the same time, Chen Ziyang thought that he had two compasses in his hands, and he could calibrate the two compasses with each other and mark the other compass to ensure that the direction he was walking was always correct and that there would not be too much deviation.

With these two compasses in his hands, Chen Ziyang's confidence increased greatly, and at the same time he sighed in the direction of the second dried corpse in his memory, maybe this dead feng shui master surnamed Du was the noble person of his life. If he hadn't entered here a few years ago and died here, there's a good chance his compass wouldn't have stayed.

At this time, in this dark space without any references, if you don't have these two compasses in your hand, it is very likely that you will lose your way as you move forward, and you may pass by the destination you want to go.

Chen Ziyang heard a story about a scientist who once experimented with a person in the desert without any reference and asked him to go in one direction, and the final result was that this person walked in a very, very large circle, but this person always thought that he was walking in a straight line. This phenomenon is said to be related to the rotation of the Earth.

This is the case with Chen Ziyang now, even if he knows the direction he is going in this dark space, if there is no reference, it is easy to have a large deviation. But because of the two compasses at this time, the possibility that he could go in the same direction all the way became a reality.

If the two of them swapped places, it was Chen Ziyang who came to this place first, and there was a very high probability that he would get lost here and die here. I just don't know if this Feng Shui surnamed Du will also find his body after entering here later, and whether he will also use the same method as himself to determine the destination.

However, Chen Ziyang only entered here later, but this feng shui master surnamed Du Du left Chen Ziyang a compass that he needed the most. This is what the Taoists call chance.

Holding two compasses in his hand, Chen Ziyang watched as the compasses calibrated each other and headed towards his destination.
