The place of Waikou Mountain is really strange, because the geographical location of this place is surrounded by special mountains, one mountain after another, one vein after another, the mountains are intricate, and the magnetic field of this place is very unstable, so Zhan Nanwei took out the compass before to determine the direction of the Western Regions There is actually a big error, but Zhan Nanwei did not notice it, not only Zhan Nanwei did not notice it, Ke Ting, Zhan Beichen They did not find it.

In fact, this didn't just happen to them, many merchants and horse gangs came and went, and when they arrived at Waikou Mountain, there was a good chance that they would lose their way and not notice anything abnormal. Only locals know the correct way to cross Waikou Mountain, but the local villagers of Waikou Mountain rarely come to this place, so the chance of meeting a local Rao here is relatively close.

Zhan Nanwei and his party were no exception this time, they were lost. They drove for about two hours, and they could always find some of the same trees regularly, and at the same time, Ke Ting and Zhan Beichen also found the same problem, and a few of them stopped the car and Zhan Nanwei said: "Fourth brother, I don't know if you have found it, we don't seem to have made much progress in these two hours, we always go around in circles in one place, about half an hour and one reincarnation, and then we go back to the same place, what's going on?" "Don't hide it from your second brother, I also feel that we are spinning in place, as if it is a labyrinth, the mountains of this Waikou Mountain are like a lotus flower, and we are back near the lotus center as we walk, it is really strange, it would be nice if Mr. Ghost Operator was here." Zhan Beichen Road.

"I heard from a friend of mine who stayed abroad before, most of the places with many mountains and dangerous places have unstable magnetic fields, and some of the methods left by my ancestors to identify the direction are not effective here, and I have never understood what the magnetic field means. Now I probably understand that there is a high probability that the compass will fail in this place. Even barely worked. Ke Ting added.

Zhan Nanwei took out the compass again, the direction of the pointer is always fluctuating back and forth in an interval every few minutes, and it is a dynamic pointing in this range, and when I took it out for the first time, I probably took it out and ignored this problem, and this time I found this problem seriously. The needle of the compass is wrong by one millimeter on the instrument, and there may be a difference of several kilometers in reality, which is a millimeter of error, a difference of thousands of miles. "What can I do? Will we be able to get out of this pass tonight? Shen Chuhua said anxiously.

Zhan Beichen replied: "It depends on our luck today, see if we can meet a local villager today, if we do, let him take us out, if not, we can only wait for the sun to rise in the morning, we will determine the direction according to the sun." ”

At this time, Ruan Shitian said: "When I used to go to a private school, I listened to Mr. Teach's visit by chance, not only to determine the direction of solar energy, but also at night. But how to determine the direction, he didn't at that time, because I didn't care about these issues. I didn't ask in detail."

"How can you be sure at night? If you can't see anything in the dark, will you be stargazing at night? Zhan Nanwei asked puzzled.

Ye Ru said: "Let's give it a try tonight, maybe we can really find something from the stars." ”

Zhan Nanwei said: "My baby, how many grains of sand there are on the ground, and how many stars there are, can you count them?" ”
