In a short time, all of us had already entered this entrance, which was surrounded by crystal stone walls, and the space of this cave entrance, we could only crawl forward, not even raise our heads slightly, and tilt our bodies, after all, it was too short to be good, and Abu was even complaining in the back. Pen & Fun & Pavilion www.biquge.info

Abu said: "Do you say that these tomb repairers are sick, and if you repair the tomb, you should repair the tomb well, and how can you design these narrow passages that are not there, I am about to get tired of crawling." ”

As soon as I heard it, I almost didn't kick Abu over, Abu was behind me, but this time I was smart, not behind Abu at all, the last time Abu's fart thing has become a shadow in my heart, so this time I'm in front of Abu, and I'm even holding back a fart at this time, so that Abu can also try this taste of eating other people's farts.

While Abu was still talking, suddenly a shadow floated out of the narrow hole as if something was covering us, and we were completely stuck in the hole, and it became difficult to turn around, so that it was impossible to turn around, so we could only continue to climb forward.

And the shadow flew from behind us, and all of us became nervous, and Zhang Yuntian exclaimed in the back: "What is that!" ”

"Don't worry, keep climbing!" The master said lightly, after all, there is the master behind, if that thing is a yin spirit or something, it should have no effect on the master, after all, the master and the unicorn blood, everything with a little yin energy, can't provoke the master's masculine and rigid unicorn blood.

When we heard the master say this, we didn't care about anything, Li Yahong didn't care either, just crawling in front, the second uncle and my father followed in front, but I couldn't care so much in the middle, anyway, if I really encountered something strange, it wasn't me who would suffer first.

But just as I was still thinking so, Li Yahong suddenly shouted: "Lower your head!" ”

We don't know what happened yet, we saw that Li Yahong had lowered his head, and then we also lowered our heads, but Wang Dashan still didn't react, behind Wang Dashan was the old lady and Qianyu, and the master was at the back, and even the master didn't hear what Li Yahong was saying.

At this time, I suddenly felt a chill on my back, it turned out that there was not only one shadow that had just flown past, but many, I only felt the sound of wings flapping behind us, the sound could not be dispersed for a long time, and when the sound slowly disappeared, we slowly raised our heads.

And one of them seemed to hit Wang Dashan, and it actually fell, Wang Dashan took the thing in his hand and shouted: "Fuck this is a flying mouse!" ”

When I heard that it was a flying mouse, I didn't fully react, but I tilted my head slightly, and glanced at the things in Wang Dashan's hand with my spare eyes, only to see that it was actually a bat, but it was not very big, much smaller than ordinary bats.

"Put it away!" When the master saw the bat in the back, he hurriedly shouted.

Wang Dashan was so shocked by the call of the young master that he threw the bat in his hand and threw it on the crow's head, and the crow was so frightened that he hurriedly scratched his head, but his mouth kept making frightened sounds, and he didn't know what he was talking about.

Wang Dashan suddenly covered the crow's mouth and said, "Don't make noise, these bats have good hearing, maybe they will come back." ”

But as soon as the words fell, I only heard the sound of wings flapping from outside the cave entrance, and then I only heard a pop sound, I knew that it was the sound of the master pumping the halberd, and the master just shouted: "You go first!" ”

At this time, Qianyu also said: "You go first, Liu Qingxuan and I can do it!" ”

We originally wanted to stay, but this hole was too narrow, and we couldn't show our skills at all, and staying would only drag them down, so Li Yahong shouted: "Keep up!" ”

Although I was entangled in my heart, but there were no extra thoughts, after seeing that the second uncle and my father also followed, I had to follow behind, Abu soon followed, looking at this situation, only the master and Qianyu were left behind, maybe Zhang Yuntian is also in the pity, after all, looking at Zhang Yuntian's attitude towards Qianyu, the feelings are very unusual, and Qianyu's feelings for the master are not clear in one or two words, sometimes, what is a person's attitude towards another person, can be seen from a look.

And those bats, it seems to live in this hole all year round, but I don't know why they suddenly flew out so much, bats are pterocods, pterocods are the second largest group of animals after rodents, is the only class of mammals that have evolved to really have the ability to fly, except for some islands in the polar regions and oceans, distributed all over the world, in the tropics and subtropics bats are the most, most of the bats are resting during the day and foraging at night.

The bat's wings evolved from their forelimbs during the evolution of the bat's skin, which are connected by their slender claws. That is, the wing membrane is composed; The snout of bats resembles that of a rodent or a fox. The outer ear protrudes forward, is large, and is very flexible in movement. Bats have short necks, broad thorax and shoulders, well-developed breasts, and slender hips and legs.

With the exception of the wing membranes, bats are covered with hairs all over their bodies and have different shades of gray, brownish-yellow, brown, or black on their backs, while their ventral sides are lighter in color. Most bats also have a keen auditory orientation, or echolocation system, which can send out ultrasound waves from their throats and then use the ultrasound responses to identify directions and detect targets.

There are some species of the face that have evolved special structures that increase sonar reception, such as nasal lobes, multiple folds on the face, and complex large ears. Bats symbolize "good fortune" in traditional Chinese culture. Humans invented radar through this characteristic of bats, and with the exception of flying foxes and fruit bats, most bats feed on insects, play an important role in the balance of insect reproduction, and may even help control pests.

Some bats also eat fruits, pollen, and nectar; Vampire bats in tropical America feed on the blood of mammals, large birds, and even humans. These bats sometimes transmit rabies, and bats have a worldwide distribution. In the tropics, bats are extremely abundant and will form large swarms in people's homes and public buildings.

Today, we finally see real bats, which feed on insects and have echolocation systems to varying degrees, so they are known as "living radar". With this system, they can fly and catch food in complete darkness, use echolocation in the face of heavy disturbances, and emit wave signals without affecting normal breathing.

They have structures called nasal lobes on their heads and noses, and are surrounded by complex skin folds, which are strange biowave devices that emit waves and emit high-frequency bio-waves continuously. If they hit an obstacle or a flying insect, these waves are reflected back and then picked up by their extraordinarily large pinna, allowing the feedback to be analyzed in their tiny brains.

This kind of biological wave detection sensitivity and resolution is extremely high, so that they can not only judge the direction according to the echo, locate their flight path, but also distinguish different insects or obstacles, and effectively avoid or pursue, bats rely on accurate echolocation and incomparably soft skin, hovering freely in the air, and even can use dexterous curves to fly, constantly changing the direction of the waves, in order to prevent insects from interfering with its information system, taking the opportunity to escape.

But we don't know if these bats eat human flesh or not, but seeing their ferocious offensive, coupled with the sound of bats organized by Xiao Ye and Qianyu in the back, maybe these bats eat human flesh.

But by this time, several bats had already flown in front of us, flapping their strange wings in front of us.
