At the beginning, I traveled through the wilderness, and I controlled the beasts to survive.

Uh-huh!

Suddenly, a black shadow thicker than an ordinary person's waist suddenly popped out from the shadow of the woods. At lightning speed, it wrapped around the body of a classmate and tried to drag him inside.

Han Ning saw this and yelled: "Yinyi! Stop it!"

"Bo!"

Yin Yi also discovered this black shadow. The leaves under her body shook slightly, and all her strength exploded, and she was instantly ejected with her body.

A silver thorn flashing brightly appeared as it rushed, and simultaneously shot into the rapidly retracting black shadow.

boom!

In mid-air, the moment when the silver thorn and the black shadow intersected, there was a dull explosion. The black shadow, which was still menacing just now, was instantly blown into two sections by the silver thorn.

Yin Yi swayed, picked up the caught student, jumped a few times, and returned to the anemone wood protective formation.

It wasn't until the black shadow fell to the ground that everyone could see clearly through the light of the flashlight. It was a thick black vine, which was slightly different from the vine whip transformed from the anemone tree.

"Vine?" Han Ning looked at the huge vine on the ground and his expression changed.

Could it be said that there are plant-based soul beasts in the woods?

"Huh...Han Ning, Yinyi...thank you for your life-saving grace."

The rescued classmate patted his chest in fear and quickly thanked Han Ning and Yin Yi.

Han Ning smiled and said: "Not to mention this, we should seize the time and clean up the remaining snakes as soon as possible."

As the vine sneak attack failed, the remaining sporadic iron-toothed snakes stopped attacking and retreated back into the forest.

"A vine? There is a soul beast more powerful than an iron-toothed snake hidden in the woods. Do we want to go in?" Several students looked at the vines on the ground and asked Teacher Lu Xiuning.

"Han Ning, what do you think of the power of this vine? Can we stop it?" Lu Xiuning turned to look at Han Ning.

Han Ning frowned and replied carefully: "The power of this vine is not too strong. It was just a surprise. If faced with 2-3 such vines, Yinyi can defeat them. If there are more... the situation will be It’s hard to say.”

Lu Xiuning nodded: "In this case, the only choice is to use the drone to explore the situation inside before making a decision!"

"Everyone retreat 20 meters. Don't worry about the snake corpses on the ground for now. It won't be too late to come back and collect them after the incident is over."

After speaking, he raised his hand to signal everyone to retreat.

After receiving the order, everyone took the anemone tree and retreated to a relatively safe place to stand.

Lu Xiuning took off the backpack behind him, took out the drone, and placed it on the ground.

He took out a special lens and mounted it underneath the drone.

"Teacher Xiuning, what kind of shot is this?" Han Ning asked curiously.

"Industrial infrared thermal imaging + night vision camera, suitable for night exploration."

As Lu Xiuning explained, he tied a small and lightweight flashlight to the drone.

This drone itself has a highly penetrating light source, and coupled with the light of the flashlight, it can well mark the general direction even in the dark night sky shrouded in white mist.

Mr. Lu, who has a background in mechanical engineering, installed various equipment quickly and steadily. In less than three minutes, a specially modified drone appeared in front of everyone.

Lu Xiuning held the control device in his hand and controlled the drone to slowly float into the air.

The flashlight and drone's built-in search function illuminate the space below with a radius of 5 meters.

The indicator light of the infrared camera flashes one after another.

Buzz~

Following a low beep, the drone penetrated the white fog, flew 5 meters above the grove, and gradually explored the area outside the east gate.

Lu Xiuning looked solemnly at the direction of the drone's light, and carefully controlled the control device to prevent the drone from hitting a tree branch and causing a collision.

Gradually, the drone flew farther and farther, until it flew into an area about 50 meters away from everyone, and a dull roar came from the forest again.

The moment he heard the sound, Lu Xiuning shook his hands and quickly controlled the drone to increase its height.

The next second, a black shadow invisible to everyone passed under the drone.

The breeze brought by the black shadow shook the flying drone slightly, and even everyone watching from a distance could vaguely see the blurry light source swaying slightly.

"Teacher Xiuning, fly a little further and roughly fly around the area outside the school." Han Ning suggested.

"But... I can almost no longer see the source of light." Lu Xiuning began to prepare to control the drone to return.

"I can see it, let me point you in the direction." Han Ning squinted his eyes and looked at the still clear light source and said.

"Go forward, don't change direction, fly straight."

"Okay, continue flying and climb to an altitude of 5-10 meters."

"Lower the altitude and try to make the drone make a circle to search the area 30 meters below." Lu Xiuning followed Han Ning's instructions and said in a solemn tone after one operation, "I have completely lost everything now. Human-machine vision.”

"It's in our 13 o'clock direction, about 30 meters above the ground."

Han Ning's pupils contracted and expanded rapidly to a degree that no one else could see, and there was always a faint white light looming in his sight.

"Okay, now adjust the direction and let the drone return."

Lu Xiuning was like a blind man, obeying Han Ning's command and controlling the drone.

Not long after, that faint white light reappeared in everyone's sight.

The moment they saw the drone, everyone let out a long sigh of relief.

Then, Lu Xiuning controlled the drone, returned quickly, and landed smoothly.

After the drone landed, he took out the memory card from the infrared camera, inserted the memory card into the portable card reader, and then inserted the card reader into the tablet.

The video on the memory card was imported into the computer, and then Lv Xiuning opened it with professional software.

The video screen switched to infrared mode.

A patch of red and green blocks occupied the center of the screen.

Among these mixed blocks, there were red blocks similar to snakes, and large patches of green blocks with lower temperatures.

For each block area, there was software calculation to simulate the approximate temperature.

The video screen moved very quickly and was very unstable.

Yin Yi and other silver lotus trees were guarding the periphery, and everyone gathered behind Teacher Xiuning, staring at the screen, unwilling to miss any details.

"A large number of shaking red blocks should be iron-toothed snakes, and there are not many..."

"These long dark blue blocks are the wire mesh on the wall, right?"

Lv Xiuning adjusted the video playback speed to the slowest and analyzed the content of the picture frame by frame.

"Wait, Teacher Xiuning, drag the video screen forward 5 seconds."

The video screen became slower in Han Ning's eyes. He carefully observed the screen and suddenly found a blue shadow passing by in the corner of the screen.

Lv Xiuning followed Han Ning's instructions and dragged it back 5 seconds.

"Pause! It's here!"

Han Ning stretched out his hand and pointed to a small color block on the lower left of the screen, saying, "Did you find that this color block looks a bit like a human thigh?"

"It seems to be true..."

"It's long and thick on the top, thin on the bottom, and there is a round part at the bottom... Could it be?"

"Did you find that there are radial color dots nearby?"

The people around him looked serious.

"Teacher Xiuning, can you switch to night mode?"

No need for others to say, Lv Xiuning has already operated the screen, adjusting the left side to infrared mode and the right side to night mode.

In the blurred picture of black and green, a black, long and blurred shadow lay quietly on the grass.

After comparing the left and right, everyone came to a conclusion that they didn't want to admit.

This... is a human thigh.
