Sometimes rain has its advantages; for example, the soil I'm digging now is relatively easier to excavate.

Digging a ditch that leads straight to the outside is not difficult, but I didn't expect that this ditch would be about 1.5 meters long. It seems that this boulder is really big.

If Top and I had run even a little slower back then, we'd probably be potato chips by now.

A ditch was dug, and the wind below flowed into the stone casket, creating convection with the holes in the cave ceiling. With air flowing inside the casket, breathing became easier again.

Anyway, the air is now circulating inside the stone casket, so I'll be the one digging now, and Top will be in charge of transporting the excavated soil to the side and piling it up for now.

I began digging a circular tunnel downwards. The curved structure can distribute the pressure from the boulders above to the greatest extent, making the tunnel safer.

Excavation is a very physically demanding job, but luckily we were on good terms today and didn't encounter any obstacles like rocks as we dug along.

The excavation is progressing faster than I expected.

Because the soil was quite moist, after about half an hour of work, Top and I dug out a circular tunnel about one meter in diameter and one and a half meters long.

I told Top to go out first, then handed the basket to Top outside, and escaped from the stone coffin that had trapped us all night.

After coming out, I took two deep breaths of the fresh air of nature and felt a sense of rebirth, as if I had been brought back to life.

People are always like this; they don't know how to cherish life when they are healthy.

Only after experiencing life and death will you realize that the preciousness of life does not lie in how much money you make or how much you achieve in life.

The scenery along the way in life is the greatest reward for oneself. Although there will be many hardships and sorrows along the way, just like I am now.

Only by overcoming these difficulties and hardships can we usher in a new life, looking forward to the sun rising again tomorrow.

I looked around at the terrain and saw a scene of devastation caused by mudslides.

At this moment, some trees as thick as a person's embrace are still standing in place, but their leaves have become very sparse and many of their thick branches have broken off.

The bedrock of those mountains was also exposed in large sections due to the landslide, making it look like a giant whose head had lost its face, which was somewhat frightening.

After all this commotion, the stream I used for navigation has completely lost its connection with me. I can't even tell which way is north, south, east, or west around me anymore. The most important thing now is to determine my current location.

The worst thing you can do in the wild is to lose your way and run around blindly based on your instincts. You're very likely to run further and further away and not only fail to get back to camp, but you might also get lost in the wilderness.

Every year, many inexperienced beginners lose their way and fail to correct their mistakes in time, leading them further astray.

Finally, they were basically the kind of wilderness novices who brought their own food and camped, needing a gas stove and canned gas to maintain their basic needs even when they needed fire.

So if they encounter any unexpected event, or if they don't, one more unexpected event will follow, and they will eventually fall asleep and return to the embrace of nature.

I had a magnet in my basket when I came out, just in case such a situation occurred.

I naturally carried some sewing needles with me, and now I can make a simple compass from these two items.

Making a simple compass is not difficult; all I need is a small leaf.

Because it rained yesterday, there are still many small puddles on the ground.

I placed a leaf on one of the small puddles. Then I rubbed an iron needle with a magnet for a while, and placed the magnetized iron needle on the leaf. A simple compass was thus made.

Now you can see the leaf slowly rotating under the influence of the magnetized iron needle, eventually stopping in one direction.

At this point, you'll find that no matter how you move the leaf, it will eventually stay in the same spot as before.

However, simply making a wilderness version of a compass is not enough. Currently, there are no north, south, east, or west markings on the pointer, so there is not much difference between looking at it and not looking at it at all.

The task now is to mark the important directions on the compass.

Here's a simple method that comes in handy, since the sun is out now, which is a rare treat. I'll use the sun's position to determine the location of my things.

I first stuck a small twig next to the puddle where I put the leaves, and then the sunlight would shine through the twig and cast a shadow on the ground.

I also stuck a twig at the end of the shadow, and the two twigs now formed a straight line.

Next, you just need to wait in place for about ten minutes. As the sun's position changes, the shadows on the ground will also move around the first tree branch as the center.

Because it is morning, the moving shadows will only get shorter and shorter before noon.

Then I inserted another branch at the end of the newly moved shadow, and connected the end of the first shadow to the second shadow to form a straight line.

Draw a horizontal line at the middle of a straight line, and the four cardinal directions (east, south, west, and north) will appear accurately in front of me.

This three-point positioning method utilizes the principle of the sun rising in the east and setting in the west to determine direction.

When a pole is erected, it will inevitably cast a shadow on the ground under the sun.

At this point, a single shadow is not enough to determine the location of things. Waiting for ten minutes is to allow the sun to change so that the direction of the shadow's movement can be determined.

Because the sun rises in the east and sets in the west, the shadow cast on the pole is the opposite, moving from west to east.

The direction in which the shadow moves toward the first branch that forms the center is due east, and the end of the shadow is due west.

Now that we know the east-west direction, determining north and south is very simple.

At this point, the person stands in a position where the east-west orientation has been determined, with their left hand facing west and their right hand facing east.

According to the principle of north at the top, south at the bottom, west on the left, and east on the right, right now we are facing due north in front of us and due south behind us.

Mark the four corresponding points on the ground with east, south, west, and north. Because of the Earth's magnetic field, the direction the compass needle points will always be north and south.

This direction is consistent with the north-south direction I drew with my shadow, which proves that there was no misjudgment or error in the process. Otherwise, we would have to start over.

This situation usually occurs because people confuse morning and afternoon, which is also important. Because the sun is in the west in the afternoon, the measured results will be the opposite.

With accurate location information, you can determine your location based on the direction indicated by the compass needle.
