173 Swim over

The helicopter flew farther and further, gradually entering the white sea. At this time, from the helicopter's porthole, there was nothing outside, and the sea and sky were all the same.

The helicopter flew forward for a while, and the instructor's voice suddenly sounded in the cabin: "All students, get up, get up, get up, prepare to take a storm!"

Recruiting?

Li Yu was startled.

Now the helicopter is hovering over the sea and the ropes are descending... Then it will fall into the water?

These guys...don't they ask the students to swim to the Marine Academy by themselves, right?

Li Yu looked up at the instructor in shock.

But the instructor did not explain. He just walked from one end to one end and woke everyone up with a loud voice. If someone was still closing his eyes, he would kick it out, as savage as a slave trader.

Li Yu lowered his head and looked at the opposite side.

Hikina also looked confused, then shrugged at him.

"All students, get up and prepare to take a storm!" The instructor shouted with a loudspeaker: "After the storm, everyone swam forward in the southeast direction. Just swim twenty kilometers to the Marine Academy. Repeat it and swim southeast direction all the way to the Marine Academy. However, if you haven't returned to the Marine Academy before 6 pm, then the training qualification will be cancelled this time! Repeat again, you must return to the academy before 6 o'clock, otherwise the training qualification will be cancelled!"

After listening carefully to the instructor’s request, Li Yu couldn’t help but curse in his heart!

It’s a vast white area here. Who knows where it is the southeast? How to travel?

Besides, I didn't say anything about swimming over before, they were not prepared at all.

But scolding is useless. After a while, a group of people were driven out of the helicopter by the instructor.

Li Yu naturally had to slide down the rope to the sea from the open hatch door on the helicopter's belly.

The sea water is a little cool, but it can be tolerated.

If you want to return to Nava Marine Academy on time, the most important thing is to find the right direction, but the question is that there is a vast white area here. Where can I find the direction and what should I use as a benchmark?

Not only was Li Yu confused, but the other students were also confused, especially many students who had not received Marine Corps combat training, and were even more at a loss.

Although this training was a Marine Corps combat training, not all the students were from professional Marine Corps. Some countries did not have professional Marine Corps due to restrictions on conditions. However, they wanted to understand the operations of the Marine Corps, so they selected other special forces members to participate in the training. Nava did not identify the students. As long as they sent them, they would accept them. Of course, after receiving everything, they had to follow their arrangements!

Li Yu was looking around in a daze, and Xijinna suddenly swam towards him.

"Hi, Lee, where to swim?" asked Hikina.

"I don't know either." Li Yu shrugged.

He actually knew it, but he was not in a hurry to show it. He wanted to see Hikina's background.

But it is obvious that Hikina has the same idea as him. Now everyone is testing it.

At this time, someone shouted: "One side, we should swim to this side, hey, come to this side quickly. I remember which direction we were flying from, so I know where we should go!"

When many team members heard this, they hurriedly swam towards the person.

"Did you go?" Xijinna looked at Li Yu.

But Li Yu was unmoved.

He actually didn't know whether the direction the student was talking about was right, but he felt that the student was very likely to be wrong, because he vaguely felt that the helicopter did not fly straight when it came, but turned a corner, and even went around in circles. The reason for this feeling was that he felt that the instructor could not be so mentally retarded. Since he decided to punish them, he would definitely punish them hard!

Another one, if he remembers correctly, he remembers that although he had been closing his eyes before, he felt that the helicopter had slightly rolled slightly. Once the fuselage rolled, his body would definitely feel it. After all, he was a Wolverine.

So he was not moved by that student.

Besides, he felt that no matter what, it was better to rely on himself.

He has not conducted professional training and learning on military terrain, but he has taught him some basic things and some very useful skills. He has also read some books before. In addition, before coming here, that is, during the two days of rest in the Kingdom of Palestinian Kingdom, he also read some foreign books on the Marine Corps, so he still knows some theoretical things.

The first priority at present is to judge the direction.

The easiest way is of course to use a compass, but unfortunately they have nothing, so they can only take the most primitive measures.

The best solution is to watch the sun during the day and the stars at night.

Of course, there is a prerequisite for this, the weather must be good.

The weather is pretty good today.

There are many ways to judge the direction through the sun. There are three commonly used ones, one is the shadow method, the other is the watch method, and the other is the land object method - this method can be used in rainy days under certain conditions.

The shadow method is to use a straight branch and insert it vertically on the ground. The top position of the branch shadow is A. After 10 minutes, the top position of the shadow is B. The direction of A→B is the direction of west→east. In the northern hemisphere, the line connecting AB is perpendicular, and the end facing the sun is the south.

In the watch method, the watch is placed horizontally, and the position indicated by the hour hand (24-hour system) is halved toward the sun. The direction indicated by the 12 o'clock scale on the dial is to summarize the north.

If the time is 16 o'clock, the scale of the watch at 8 o'clock points to the sun, and the scale of the 12 o'clock refers to the north. In summary, it is: the number of hours is half to the sun, and the number of 12 o'clock refers to the north.

According to the method of land, the branches and leaves on the south side of independent trees are lush and the bark is smooth. The annual ring lines on the stumps are usually sparse in the south and dense in the north. The snow in buildings, mounds, ridges, and highlands usually melts quickly in the south and slowly in the north. Large rocks, mounds, and large trees are dense in the south, while moss is prone to growing in the north.

At this time, Li Yu and the others were located in the sea, and the more suitable ones were the shadow method and the watch method.

The shadow method is the easiest way to find a floating branch on the sea surface, hold it vertically in the water, record the position of the shadow at this time, wait for about ten minutes, and then observe the position of the shadow and find the direction of the shadow moving.

Through judgment, Li Yu found the direction at this time.

In fact, the watch method is simpler, but their watches are all put away and there is nothing on them.

After judging the direction, Li Yu pointed to the southeast and asked Xijina: "I want to swim here, where are you?"

"I'll follow you." Hikina said with a smile.

Of course she knew where to go, but she didn't say it.

The sea water soaked her clothes, making her sexy figure even more seductive. This is her biggest advantage at present!
