Wu Fan came to the negative angle of the mountain five or six thousand meters away, looked up at the mountain with a strong yin qi, and took a long breath.

The mountain peaks plunged straight into the black clouds, and the whole mountain peak was gloomy like a ghost, the wind was blowing, and there was occasionally an animal cry, which was sharper than the white ape, and more miserable than the cuckoo.

Wu Fan began to climb upward, with nanoropes several thousand meters long wrapped around his body and hundreds of rock wedges in his back pocket.

(PS: Rock wedge, a necessary tool for rock climbing, can be embedded in the stone crevices, penetrate the rope, and play a safety role.) )

The cliffs are cut with knives and axes, and there are few large rock crevices, and there are some slippery moss on the rock walls, which makes it more difficult to climb.

Wu Fan's finger power is amazing, as long as there is a slight bulge or crack, he can pick it and lift the weight of his whole body.

Even so, Wu Fan was very careful, every time he climbed more than ten meters, he put a rock wedge in the rock crevice, and passed through the nanorope to ensure that once he fell off the cliff, he could be pulled by the rock wedge in the rock crevice.

After a while, climbing to a height of about two hundred meters, Wu Fan paused, took a sip of iced tea, and slowed down for a while.

The trees under the mountain swayed in the strong wind, like ghosts.

Wu Fan continued to climb up.

About 500 meters away, suddenly the mountain wind was much quieter, and the sound of various insects disappeared.

Wu Fan cautiously continued to climb.

Suddenly, a gust of wind struck, and hundreds of palm-sized black unidentified flying objects swept over his head.

As the black unidentified object flew out, the black unidentified object made a sharp sound, which shook the eardrums.

The sudden situation made Wu Fan fall down one by one, but fortunately, Wu Fan had fixed the rock wedge under his feet, and Wu Fan, who had fallen about three meters, was firmly pulled by the nanorope that penetrated the rock wedge.

Wu Fan swayed in the air, let out a long breath, and saw the black unknown objects coming from the sky.

After more than ten seconds, thousands of black unidentified objects swept past.

"This must be a bat in a rock crevice, right? System adult. ”

Wu Fan asked.

"Ding,

Ice peak blood bats, which belong to the family of mammals.

The Ice Peak Blood Bat lives in the vast land of Yin Qi all year round and likes to live in groups.

Staple food insects and smaller animals mainly use ultrasonic echolocation signals to search for food, detect distance, determine targets, avoid obstacles and avoid predators, etc., and are especially good at night attacks.

The blood of the Ice Peak Blood Bat is extremely cold, and it can be used as medicine, which has a miraculous effect on cleaning up heat poison. ”

Wu Fan secretly thought, it is indeed a treasure, and it is not in vain to get some blood bat blood to go back.

In addition, the blood bat is good at night attack, which is even more powerful than Zatoichi, and it can accurately judge the position of the opponent even if it is completely fixed and there is no breathing or heartbeat.

If you can have this characteristic, how cool it is, no matter day or night, you can exert your peak combat power, it's beautiful to think about.

Wu Fan is a person who is good at thinking and creating.

Wu Fan was thinking about this question as he climbed upward.

The ultrasound of a blood bat may be simulated with Yi Yin, but the human ear cannot receive the ultrasound.

"Lord System, how can I have the ability of a blood bat to attack at night?"

Wu Fan couldn't help asking.

"Ding, no."

The system replied coldly.

"Can Yi Yinju simulate the ultrasound emitted by a blood bat?"

"Ding, yes!"

"Is there a way to get your ears to receive ultrasound?"

"Ding, you can use an acoustic inverter to reduce the ultrasound to the range that your ears can receive."

"Thank you, Lord System, I'm going to study this topic carefully when I go back, and theoretically I can indeed have the ability of a blood bat."

Wu Fan's brows furrowed, and he had a preliminary plan in his heart.

In the process of continuing to climb, I was not hindered by the second major obstacle, but on a few occasions with a little effort, I finally climbed to the top.

The air at the top of the peak suddenly cooled down, more than ten degrees lower than the foot of the mountain, and Wu Fan's body was a little cold.

To Wu Fan's surprise, the place at the top of the peak was actually very open, which was different from what he imagined, but thinking about the peak from this angle, the higher it should be, the larger the area, and Wu Fan was relieved.

Wu Fan bought a cotton suit in the system and put it on his body, and continued to explore with a flashlight.

The vegetation at the summit is very different from the grass at the foot of the mountain, most of them are small leaves or needles, not similar to the bottom of the mountain, and the broad leaves are dominant, which is obviously caused by low temperatures.

The mountain wind swayed the grass and trees, creating a cloud of strange shadows, more like a place of ghosts.

"Woohoo!"

In the distance, the sound of animals chirping, like wolves.

Wu Fan immediately turned off the flashlight and hid in the grass.

This can't be, I should have heard it wrong, how can there be wolves on the mountain peaks? Wu Fan secretly thought.

It should be the sound of the wind, according to common sense, on the top of the mountain, there can be no beasts to survive, some can only be birds, and they belong to the level of birds of prey.

"Woohoo, woohoo..."

The sound continued, and it grew clearer.

Are there really wolves? As True Pixel Yi said, there are really wolves on Giant Wolf Mountain.

"Woohoo, woohoo..."

The sound came from far and near, and several faint interlaced green lights were faintly visible in the air. It should be the glow of a wolf's eyes.

How can it be? With such a steep peak, I'm afraid even apes can't climb it, so how can there be wolves on it?

"Woohoo, woohoo..."

The shadows of the great are approaching, and the green light is brighter.

Nima, sure enough, is a giant wolf, there are two of them, the size of a cheetah, two searchlight-like eyes looking this way, can't see its coat color and face clearly, you don't need to think about it, you know, it must be hideous and terrifying.

The wolf's sense of smell is very sensitive, and he is bound to be discovered.

Wu Fan took out an MP5 type anesthesia gun from the system, which was also put into the system locker in the Giant Wolf Mountain base last time.

Wu Fan put two tranquilizer bullets into the gun.

This kind of anesthetic bullet has a long anesthetic time, about 40 minutes of anesthesia, and the measurement of each bullet is sufficient, enough to numb an elephant.

Wu Fan was very curious about these two giant wolves, and he didn't plan to shoot them directly, so he used a tranquilizer gun.

Wu Fan pulled the trigger.

"Biu Biu" twice, the two wolves went to the wolf, and after two whining sounds, the eyes were like extinguished lights, gradually losing their brilliance, and the huge body collapsed to the ground.

Wu Fan turned on the flashlight and stepped forward, silver-gray hair, two ears standing up, and vigorous limbs.

Wu Fan opened the wolf's mouth, his bright red tongue hung out, and the two rows of sharp teeth were very terrifying.

"Ding,

Howling Moon Silver Wolf,

It is a mammal, a unique wolf species in the Giant Wolf Mountains of Aoki Province, with a large body and a reputation for its ferocity and vigor.

Average strength: 3600

Attack: 3800

Blood and bones can be used as medicine, and meat is an excellent tonic. ”

The system prompt sounds.

"Why did you run to the top of the mountain?"

Wu Fan asked suspiciously.

"With the endless desire of human beings, the habitat of wolves is no longer safe, since the development of the wolf mountain range in the last century, the giant wolves on the giant wolf mountain have almost become extinct, one of them escaped to the top of this peak, and has survived and multiplied so far, only seventy or eighty."

Wu Fan took out a medicine needle in the system, took out a small tube of wolf blood from the vein of the wolf's leg, and put it in the system locker.

Wu Fan carefully plucked a few hairs on the wolf's body and put them in a box for storage as a specimen.

If you have time to go to the laboratory of Qingbei Chemical Research Institute to let Song Xin and the beautiful woman research and research, maybe you can research something.
