Snowflakes floated over the vast snowfield, the cold wind howled, and the terrible howling sound was like the howling of the evil ghosts of the eighteenth layer of hell, sharp, piercing, with a certain palpitating demonic nature, and people who were not firm enough would be absolutely frightened and panicked when they heard this sound on the snowfield, until they collapsed.

In the snow cave, the cold wind poured in, and the sound was even more terrifying. The thermal insulation effect of the sleeping bag is very good, but the snow field is too cold, Yang Zheng feels like sleeping in ice water, listening to the terrible wind outside, very uncomfortable, remembering the method mentioned in the video, he quickly shrunk his body into a ball, clamped his arms, protected his stomach with his hands, constantly adjusted his breathing, shook his muscles to produce temperature, and gradually, there was finally some temperature in the sleeping bag.

After a while, the temperature of the sleeping bag was a little warmer, and Yang Zheng felt that his body was back, listening to the terrible wind howling outside, thinking that there was only one person in the entire snow field, what if the snow wolf foraged for food? There can't really be an unknown creature on this snowy field, right?

When people are in danger, all kinds of negative emotions will come up like a tide, and people with insufficient willpower can scare themselves to death, Yang Zheng knew that it would not work like this, so he quickly put aside his distracting thoughts and recalled the new eagle grappling boxing created by integrating military body boxing, grappling fighting boxing and traditional eagle claw boxing with Gao Shou.

The new Eagle Claw Boxing integrates defense and offense, but when the traditional Eagle Claw Boxing was taught to Zhao Lei this month, Yang Zheng found that there were still some deficiencies, but he didn't understand what it was, and he just couldn't sleep, Yang Zheng carefully deduced it, pretending that the enemy used all kinds of tricky and ruthless offensive methods, how to counterattack in the face of these methods, and how to take into account the two major elements of defense and offense, and how to be flawless.

I don't know how long it took, Yang Zheng gradually entered his own world, forgetting that he was in the snowfield, and he couldn't hear the terrible cold wind howling outside, and fell asleep in the boxing deduction, and when he woke up, it was already bright.

Yang Zheng got up and found that his body was in good condition, and he didn't have the backache when he slept on the snow ice platform mentioned in the video, so he couldn't help but wonder, could it be that the muscles of the body were kept active when he deduced the boxing technique, so that the blood circulation was normal, so there was no pain?

After thinking about it, I don't know the essentials, but it's a good thing after all, Yang Zheng didn't bother to think about it, quickly packed up, packed all the things into the backpack, folded the sapper shovel and hung it on the backpack hook, the first night on the snow field can survive, Yang Zheng has some confidence and confidence in the future.

Not long after, Yang Zheng packed up, threw the backpack up, climbed out of the snow cave, a cold wind blew, and countless cold demons drilled into the neck, Yang Zheng quickly took out the goggles and put them on, brought the scarf and hat, pulled the scarf high, covered the face, and then put the backpack on his back, picked up the dogleg knife and walked forward slowly.

Not to be outdone, the cold wind swooped over, quickly taking away Yang Zheng's body temperature, Yang Zheng felt that the muscles of his whole body were shivering from the cold, and the heat was dissipated quickly, so he quickly tensed his body and endured it, took out the map and opened it, and took out the compass to study it.

The next thing is to start the march, surrounded by vast snow-capped mountains, it looks like there is no difference, it is easy to go wrong, once you go in the wrong direction, the consequences are very serious, Yang Zheng did not dare to be careless, put the compass on the map, carefully study it, the dot symbol represents the boulder, tomb, cave and other small in size, but there is an important reference to the object; The line symbols represent rivers, channels, roads, etc.; The polygon symbols represent meadows, lakes, swamps, forests, etc., and those who don't understand them can't read the map at all.

As for the curves on the map, they represent the basic contour lines, which are drawn according to the basic contour distance, and the inter-contour curves that use the contour receipt contour line that is half of the basic contour distance in order to express the local geomorphological features, which are usually represented by long dashed lines.

There are also auxiliary contour lines, which are usually depicted at quarter contour distances, but contour lines can also be depicted at arbitrary heights to represent important terrain that cannot be represented by basic contour lines and inter-curves, and are usually depicted on a map with short dashed lines.

If you know how to read the map, you can directly obtain the outline, location, length, area, height, size and other data of the feature on the map in combination with the scale.

The mantra of reading the map is to first point and then line, from the line and the surface, first find out the obvious point terrain on the map, such as the peak of the highest peak of the mountain range, and then find the river, mountain, valley, etc. of the linear terrain, at this time the general topography of the whole map will be understood, and then look for lakes, grasslands, open spaces, etc., and the entire terrain will be known.

It is much more convenient to walk after understanding the map, from the starting point to the end point, there will be a lot of mountains, canyons, rivers and other obstacles in the middle, and you must detour, so it is difficult to return to the original route, resulting in getting lost, which requires mastering the azimuth skills, and you will not get lost if you walk according to the azimuth.

Military compass is usually measured counterclockwise, and the bearing angle is read according to the compass scale. First, lay the compass horizontally, wait for the pointer to stand still, mark the bearing, hold the compass, face the direction you are heading, read the bearing value on the dial, and remember the value.

Take out the compass at the next turn, mark the bearing, read the azimuth of your direction on the scale again, and remember it, if you are afraid of forgetting, it is best to mark it with a pen on the map, repeat the demarcation of the bearing for each turn, remember the direction of progress, if there is no way ahead or get lost, take out the compass, read the bearing, turn back to the opposite azimuth, go back to the previous turning point, take out the north arrow to read the previous azimuth, and then travel to the opposite azimuth.

To put it simply, it means that the north needle will always point to the north without considering the interference such as the magnetic field, that is, the reference direction is fixed, from point A to point B, the line and the north arrow form an angle of 30 degrees, 30 degrees is the azimuth, along the azimuth point forward straight line will not be wrong, and 90 degrees is the opposite azimuth, along the azimuth point back will not deviate from the bearing.

If point B needs to turn, a new azimuth will be formed at point C, and you will know where to go, how far it is from point A, how much bend it has turned, and you can return the same way according to the opposite azimuth, if point C needs to turn again, a new azimuth will be formed at point D, marked on the map, at a glance, and you will hardly get lost if you follow the azimuth, even if there is no map and road signs.

Of course, we have to guard against magnetic field interference that causes the angle to deviate, and the azimuth angle is not accurate, so we need other methods to identify the direction, and calculate the angle and distance in combination with the map, which is much more complicated, and inaccurate, and there is a risk of getting lost.
