I am the king of the wild live

Chapter 721 can be used as a survival signal source
In desperation, Wang Yu had no choice but to find a better landing point. Worried that the family would get lost, Wang Yu brought them back to the cave.

Based on his memory, Wang Yu walked along a dense forest in the west direction. After passing through the dense forest, there was a small open space. It seemed that there were not many sundries. Wang Yu began to build a simple beacon tower nearby.

Due to limited conditions, Wang Yu could only rely on burning semi-dry and semi-wet wood to create a certain smoke effect. Fortunately, when he turned over a hollow log, he found a termite nest at the bottom of it. .

“Good luck!”

Wang Yu laughed loudly.

"After the termite nest is burned, the formic acid will release a large amount of white smoke, which can be used as a signal source for help in the wild or even communication. Speaking of this, some viewers may think that the spectacular scene of eight hundred miles of beacon fire, In an era when the efficiency of information transmission was low, the ancients would still use wolf smoke as an ancient means of communication."

"In some ancient film and television dramas, there is often a scene that misleads the audience, saying that the beacon fire uses wolf dung as fuel, but in fact, this statement is wrong. The fuel used by the wolf smoke is not the so-called wolf dung. , but firewood, such as Populus euphratica, tamarisk, camel grass, licorice and other plants can produce a lot of white smoke after burning.

Moreover, the white smoke rises straight up and is not easy to disperse. As long as the field of view is wide enough, it can be seen clearly from dozens of kilometers away. When these plants are surviving in the wild, if they encounter them, they can be used as a This kind of survival signal source can save your life at critical moments. "

During the conversation, Wang Yu had already destroyed the nest with an engineering shovel, and found that there was serious water accumulation inside, and the small passage was full of insect eggs and dead termite adults. Although the water accumulation was serious, it was still usable. A large piece, set aside for use.

"The reason why wolf dung is not the fuel of wolf smoke is that it is very difficult to collect a large amount of wolf dung for use by beacon towers. Secondly, the digestive system of wolves is very powerful. The prey eaten by it will be digested thoroughly. Even the fluff All are spared, only some coarse wool fibers can be avoided, so there are fewer combustibles."

"Finally, the smoke produced by burning wolf dung is very light in color and easy to dissipate. It is worse than ordinary dry woodpile. If you don't believe me, there is a chance to encounter wolf dung in the wild. I can test it for you personally. look."

After all, Wang Yu found a pine log in a nearby puddle. A large section of pine log was soaked in water, and the wood had already softened a lot.

Logically speaking, it doesn't take much effort to chop. Wang Yu saw that the tip of the shovel was already curled up in his hand, but he was still not willing to use the sapper shovel. Instead, he took the stone ax at his waist, and chopped the pine wood one by one. .

"dong dong"

A muffled sound echoed in the forest. The cut was getting deeper and deeper, and sawdust continued to fly. The stone ax had a limited sharpness, and it had been worn before. It was almost a blunt instrument, even for Wang Yu. Having strength attributes that exceed the limits of human genes only speeds up this process.

"If a worker wants to do a good job, he must first benefit it. The ancients did not deceive me!"

After Wang Yu sighed, the pine wood let out a final whine, and then broke into two pieces in response.

To chop the pine into sections about one meter in length, Wang Yu first erected sections of pine trunks, and then chopped them into countless small pieces.

Wang Yu arranged the pine blocks regularly into an upright cuboid to make a simple small beacon tower, and then filled the bottom with some dry firewood and hay with low humidity before putting the termite nest in it, and finally put the termite nest on the top. Top with a thin layer of palm fronds.

Even if the pine wood is soaked, it can burn, because it contains a lot of rosin, so Wang Yu doesn't have to worry about this problem at all.

Just when Wang Yu finished everything, he planned to sit down and rest for a while, when he heard the roar of the propeller not far away, the sound gradually became louder and louder.

"We agreed to arrive in 10 minutes, and it's just past 10 minutes..."

Wang Yu hurriedly got up and prepared to burn the small "beacon tower". He took out the pine wood chips used to start the fire from his backpack. Wang Yu used the method of drilling wood to start the fire. In less than 30 seconds, a small fire was ignited.

When the fire is fed from the bottom, the flame first ignites the withered grass inside, and then the pine wood rich in turpentine. Gradually, the fire becomes bigger and bigger, and the termite nest inside also begins to be ignited.

After the formic acid burned, a large amount of white smoke came out. The pungent smell of the formic acid made Wang Yu cough, subconsciously cover his mouth and nose, and stay away from the beacon tower beside him.

A straight and thick white smoke slowly rose into the sky. The transport helicopter that was circling in the air seemed to find the target, flew along the white smoke, and then began to land vertically.

There was a loud sound from the high-speed rotation of the front and rear propellers of the medium-sized transport helicopter, and gradually the speed of the propellers slowed down, and it began to slowly land vertically.

The grass near the landing point was undulated in waves by the strong wind, and the straight white smoke was also blown away. For a while, there was a faint white smoke nearby, making people squint their eyes and detonate their lacrimal glands.

The tiny branches and leaves were constantly flying under the strong wind. Seeing this situation, Wang Yu hurriedly hugged the emperor in his arms, shielded his eyes with one hand, and watched the helicopter not far away slowly descending through his fingers, until The propeller stopped.

The hatch at the tail part of the plane slowly opened, and a bald-headed Caucasian man in a black suit about 50 years old got off the plane first, striding towards Wang Yu like a shooting star.

"Max!"

The middle-aged bald man stretched out his right hand and held Wang Yu's right hand tightly.

"king!"

Wang Yu nodded and said.

"Hello, Mr. Wang, first of all, on behalf of the Southeast Asian branch of animal protection organizations, I would like to thank you for your help and strong support!"

The white man said in a sincere tone.

"You're welcome, this is what I should do!"

Wang Yu waved his hand.

"Introduce, this is my assistant, Cole."

Max introduced to Wang Jian, and then the young black man named Cole extended his right hand to shake Wang Yu's hand in a friendly way.

Wang Yu also responded kindly.

The group of people behind them is the accompanying medical team for this operation.

There is a complete medical team of six people behind Max, including men and women, with the exception of no doubt they are all of the same age. Everyone has an excited look on their faces. Wang Yu nodded with a smile , and then they also responded with a smile.
