When ordinary people swim, they look like they are 'lying on their stomachs' on the water, because this can speed up the swimming speed and improve the efficiency of holding water between their legs. But on the battlefield, this trick is not practical. The swimmer tries to keep his body upright, which can save Lin Song a lot of physical strength.

After about half an hour, Lin Song finally landed on the opposite bank. Standing on the other side, Lin Song suddenly realized a serious problem.

That is, I have lost my bearings. When he started to swim just now, the speed of the water was very fast, and Lin Song was rushed downstream as soon as he got out of the water, and in such a hydrological environment, Lin Song stayed for half an hour, that is to say, Lin Song was nearly half an hour away from the point directly opposite.

Taking a deep breath, Lin Song took out a piece of paper from his pocket, and after forming a ball, he threw it directly into the river in front of him.

Lin Song's eyes were staring at the paper ball, and he was measuring the speed of the water flow in his heart. After having a value, Lin Song began to calculate the approximate time he had traveled in half an hour.

After figuring this out, Lin Song squatted on the ground, used the dragon's tooth saber as chalk and the ground as a blackboard, and began to draw a sketch, roughly estimating the location of the place where they landed just now.

"Good fellow, this Leon is really cunning, we are here to make trouble, he can find a new place to live in less than half an hour." Lin Song was thinking about it, and he was praying in his heart, praying that Leon would never leave.

Soon, Lin Song entered the forest and began to walk over thinking about the direction he had just calculated. But this time, Lin Song walked for less than an hour before he completely lost his direction.

This is not to say that Lin Song's ability is problematic, after all, Lin Song's previous direction was also roughly estimated by the visual inspection of Qian Donglu, and Lin Song chased in the jungle for so long, it was inevitable that there would be deviations. Swimming in the water and being swept downstream by the current further increases this error.

Walking here, Lin Song realized that this error was now beyond the limit of what he could tolerate. If this continues, Lin Song will probably need to walk for an extra day or two before he can basically find the location of the opponent's new stronghold.

To put it mildly, a day or two later, God knows if Leon is still there.

Lin Song took out the weak whistle and blew it twice, but he didn't hear a response at all. This feeling of silence made Lin Song a little depressed.

"What are you doing!" Lin Song slapped himself in the face in annoyance: "Don't rush to the plane with your life as snow wolf, you should go to reinforce the snow wolf now, instead of being depressed like a girl in this place!" ”

Lin Song said, gritting his teeth and standing up again, he looked around back and forth, but he was still at a loss, he had now completely lost his direction. There is no map, no starlight, unless you wait until dawn and roughly determine the position of the other party by the direction of the rising sun.

"No, you can't waste time!" Lin Song gritted his teeth and rummaged directly in the backpack, and soon, Lin Song found a steel needle, and then found a lighter, Lin Song used two wet branches to hold the steel needle, and burned it underneath with a lighter.

Soon, the steel needle was burned red, and Lin Song inserted the steel needle into the soil, and he heard a sizzling sound and a puff of white smoke coming out of the ground.

After doing this, Lin Song tore off a thread from his clothes and tied it to the middle of the steel needle to the rear position, and saw the steel needle spinning in the air, and after about a turn or two, it pointed in a relatively stable direction.

"That's you!" Lin Song said.

The steel needle is easy to magnetize during the burning process, and the operation similar to 'quenching' inserted into the soil can not only cool down, but also allow the steel needle to quickly absorb the metal elements in the soil and enhance the magnetism. This simple compass finally allowed Lin Song to retain the last glimmer of hope, and Lin Song did not hesitate to set off again.

This time, Lin Song walked in the direction he judged for nearly two hours. But he still didn't see the shadow of the other party's new stronghold, and after Lin Song sat under a tree and rested for a while, he wanted to continue searching.

At this moment, the east was already in the morning, and Lin Song knew that if he continued to look like this, the possibility of finding the other party would be very small, and the snow wolf would become more and more dangerous.

Lin Song pinched the weak whistle, although he knew very well that even if the snow wolf was alive now, it would be impossible for him to respond to him. But Lin Song still blew the weak whistle, as if this whistle was still there, and the bond between Lin Song and the snow wolf had always existed.

After a while, Lin Song forcibly let himself gather his thoughts and prepare to continue his departure. But this time, Lin Song only walked forward for about twenty minutes when he heard the sound of rustling from the depths of the woods. Hurriedly pulled out his pistol and waited.

In the Amazon jungle, there are many wild animals, and more than half of them are relatively aggressive. When walking here, you must have enough means to protect yourself.

The voice in the grass became more and more obvious, and it seemed that the other party was getting closer and closer to him. Lin Song tried his best to lower his body, and then found two trees as a barrier between himself and the other party.

Wild animals are like this, they have a lot of side attack ability, but they all have a weakness, that is, as long as there is an obstacle between them and their prey, these wild animals do not seem to know how to turn quickly.

The thing came up, Lin Song suddenly raised his gun, and his fingers had already pulled the trigger into a third, but at this moment, Lin Song saw that the wild animal that made the sound was actually a yellow-gray American timber wolf.

Because of the snow wolf, Lin Song had a special affection for the wolf animal, and when Lin Song saw this wolf, he hesitated and did not shoot.

At the same time, the wolf actually seemed to know Lin Song, and ran directly to Lin Song's side. Lin Song suddenly realized, I understand!

The snow wolf has a natural suppression of these canines, maybe the snow wolf has lost his freedom now, but the snow wolf can hear the sound of a weak whistle in the distance.

It was precisely because of the sound of the weak whistle that the snow wolf knew that Lin Song had never given up on it, and Lin Song had been looking for its traces in the rear. In the end, the snow wolf decided to help Lin Song, and it also made an infrasound type sound.
