I am the king of the wild live

Chapter 729 Vigilance and Defense Has a Powerful Ability

Wang Yu rubbed the fluffy little head of the other party, smiled slightly and said, "Okay, let's go together!"

Facing countless caves, Wang Yu stood under the stone wall and was a little confused for a while. He didn't know which cave to go to. Just when Wang Yu was extremely confused, he only felt a light on his shoulders.

Then he saw the vigorous emperor running along the water pool, and then climbed up into a cave as wide as a person. Wang Yu was very familiar with that cave. It was the cave where the mysterious creature originally haunted.

"Geeky!"

"Come on!"

Wang Yu chuckled, and then he stepped up the cave with the speed of sprinting, followed by the aerial drone behind him.

The figures of a man and a monkey gradually disappeared in the extremely dark cave.

The cave is a bit small for Wang Yu, who is 1.8 meters tall. It also has uneven rock walls to prevent his head from hitting him. He had to bend his waist and walk slowly while walking.

Fortunately, the cave became wider from being narrow at the beginning. After walking a certain distance, Wang Yu didn't even need to bow his body to move forward.

The situation in this cave is different from what Wang Yu imagined. I thought it was a slow downhill road, but I didn’t expect that it was actually an uphill road, and there was no fork in the middle. Wang Yu walked carefully along the cave like this .

There is no movement in the quiet cave, only the sound of dripping water from time to time, echoing in the extremely quiet cave, the sound is sometimes far and sometimes near, Wang Yu rolled his Adam's apple and felt a little thirsty, so he took out the bamboo slips from his backpack to drink , Don’t forget to pour some in the palm of your hand and feed it to the emperor standing on his shoulders.

To be honest, with the emperor by his side, Wang Yu felt a lot more at ease. As an emperor marmoset that has been specially trained by the local aborigines, he has a strong ability in vigilance and defense. In some aspects, his perception ability even surpasses that of unlocking the gene lock. Later Wang Yu.

The cave that could only accommodate one person gradually and suddenly became wider, at least able to accommodate a small car, like an underground passage.

Feeling that the air flow in front was getting stronger and stronger, Wang Yu operated the light to illuminate forward, and looked along the light, as if he found that the cave not far ahead had passed the end, and the wide cave replaced the long and narrow cave passage.

"It's very interesting. This cave is like a corridor, leading to another new cave, and the cave in front of me is like a room. I bet that there must be many large and small caves outside that correspond to many rooms. cave."

While talking, Wang Yu walked out of the cave passage. To his surprise, not only did he suddenly see the light, but the newly discovered cave was extremely narrow and long, like a straight corridor, hundreds of meters away.

It's just that there are still rocks piled up on the road in the cave, and what is even more surprising is that there is still a little moonlight shining in the "corridor".

Following the light source, Wang Yu looked up, and it turned out that there was a long and narrow crack almost as long as the cave corridor directly above. The vines growing on the mountain extended along the gap to the cave corridor, and fell in midair, about as wide as a person. The closed mountain rock seems to have been cut with a long and narrow opening by a giant axe.

"It's incredible..."

Wang Yu muttered to himself.

Suddenly, a vegetation bathed in silver moonlight on the rock in front of him caught his attention.

There was only a pitifully thin layer of dust on the bare rock, which provided little nutrition. However, this plant could grow to a height of about ten centimeters, which surprised Wang Yu.

I was about to take a closer look at what kind of plant it was, but with a light touch, the plant fell off the rock wall, as if it had been glued together with ordinary glue.

Facing the unreasonable Wang Yu, he looked curiously and carefully. Seeing that there were still seed coats and a little brown substance on the roots of the plants, Wang Yu was thoughtful.

"I get it! The reason this plant is able to grow and develop like this in the absence of soil nutrients and sunlight is because of fruit bats!"

Wang Yu suddenly realized.

"Fruit bats, as the name suggests, like to feed on wild fruits. The smaller fruit bats play a very important role in the dispersal of seeds in local areas. After eating fruits, the indigestible fruit cores will be excreted with the feces.

That is to say, the reason why the plant in my hand can still grow in such a harsh environment is because the fruit bat feces provide the nutrients for seeds to germinate and grow. "

Wang Yu put the plant in his hand in front of the camera. It looked like an enlarged version of bean sprouts, but there were several leaves growing, but these leaves looked a little malnourished and yellow.

"Using the means of excretion as a medium for spreading fruit seeds, because it is not directly rooted in the soil, so it fell off as soon as I touched it. The nutrition provided by fruit bat feces is limited, and it can grow to this extent. Worked hard!"

The appearance of fruit bats brought good news to Wang Yu, which meant that he could supplement a certain amount of protein, and even some other surprises.

"It's a pity that I'm not in the densely-vegetated rainforest, otherwise I would have learned the way of the locals, making a giant mosquito swatter, and then smashing them one by one like playing tennis."

Wang Yu said with some regret that without these materials, it would not be easy to catch bats flying in the sky in this narrow, long and wide cave.

Anyone with a little bit of biological knowledge knows that when bats fly at night, they do not rely on their eyes to process complex information, but rely on their ears and vocal organs that have evolved over a long period of time to ascertain the situation.

"During night flight, bats emit a screech, which is an ultrasonic sound, because the audio frequency is too high for the normal human ear to pick up.

Ultrasonic waves are like radar. They will be reflected back after scanning nearby obstacles. In the process of sending and receiving information, bats complete complex calculations and can avoid obstacles accurately. "

"Scientists call this behavior echolocation, and it's one of the skills they rely on for survival, you know..."

Wang Yu, who was popularizing science with the camera, seemed to hear some movement in his ears, which sounded like the sound of wings flapping. He looked up with the light on, and a group of bats hanging upside down in the corner of the crevice of the rock peak above his head were staring at him.

"Look, these guys are partying."

In order not to disturb them, Wang Yu whispered something.

"Fruit bats are also called flying foxes. Everyone knows the reason why they are called flying foxes."

While talking in a low voice, Wang Yu slowly zoomed in on the camera, and took a close-up of one of the flying foxes hanging upside down.
