"Let's go, follow them and see how the head teacher punishes them. Anyway, they will definitely not get any good results this time."
Class monitor Xu Tao and a few bold classmates followed him out, ready to watch the fun.
In less than 5 minutes, Li Yan had brought Lin Tian and others to the school's monitoring room.
At this moment, the person responsible for managing the surveillance video is a major in his 40s, Lao Wan.
When Lao Wan saw Li Yan suddenly rushing towards him with an angry face, he immediately stood up and saluted.
"Teacher Li, what's the matter?"
Under normal circumstances, school teachers will not come to the monitoring room. Of course, there are some abnormal situations that require monitoring.
Lao Wan looked at Teacher Li with a surprised expression.
Li Yan returned the greeting and said: "Lao Wan, please adjust the surveillance in the back mountain for me."
Lao Wan was stunned when he heard this, the surveillance in the back mountain?
Very few people go to Back Mountain. Although there is surveillance there, they hardly pay attention to it. Suddenly the surveillance there is called out. Could something have happened?
Lao Wan's mind was full of questions, but he didn't feel like asking too many questions. He immediately said, "Yes, you sit down and wait a moment. I'll take care of it right away."
After saying that, Lao Wan sat in front of the computer under the general surveillance, picked up the mouse, and prepared to operate.
Whoosh!
Lao Wan clicked a few times with the mouse, and the large screen in the monitoring room immediately switched to the current monitoring screen in the back mountain.
Sure enough, it was the mountain behind, and the green screen displayed on the screen was exactly like a jungle scene.
After Lao Wan called up the video, he looked back at Li Yan and asked: "Teacher Li, what time period do you need? What specific angle is required?"
Li Yan's face darkened, he turned to look at Lin Tian, and asked deliberately: "Tell me, the specific time and location of your own training?"
As he spoke, Li Yan's eyes showed a trace of pride.
That's right, this time he deliberately asked Lin Tian and the others to know the time and place of their training to see if they trained, how they trained, and whether they lied!
A group of freshmen dare to speak arrogantly, and I don't mind leaving them speechless.
Whether it is a donkey or a horse, you will know after pulling it out!
Facing Li Yan's questioning eyes, Lin Tian looked calm and said: "You can start watching at 5 o'clock this morning. If it's not enough, then adjust the ones from the previous two days, which also started at 5 o'clock and ended at 8 o'clock.
You can check carefully at any time period, and the location is clear enough from this angle."
hiss!
Li Yan listened to Lin Tian's eloquent talk with a look of disdain on his face and felt so choked up that his lungs were about to explode.
What the hell, are you still pretending at this time?
Why are you so thick-skinned, and you actually speak so seriously? Do you really take yourself seriously?
We are confronting you, is it really good to be so confident?
Since you don't know how to find a way out, don't blame me for being ruthless.
Next moment, when the answer to the mystery is revealed, I want to see how you still pretend?
The corner of Li Yan's mouth moved, revealing a sneer, and snorted: "You really know how to pick a time. It's dark at this time, but don't think that if you pick this time, you won't be able to see you in the video. It's easy to make excuses, right?"
Do you think our camera can’t capture the picture clearly?”
"Let me tell you, this is a far-infrared camera. Even in the dark, you can still take clear pictures."
Listening to Teacher Li's constant denial of his words, Lin Tian smiled bitterly.
To be honest, he didn't even know what to say.
This Teacher Li is obviously blinded by emotions and even unconscious. No matter what he says, he will feel like he is pretending.
Forget it, let him see for himself. If he says more, he will feel like he is showing off.
But to be honest, the undead people are really qualified to show off, because their training model cannot be learned by other students even if they want to.
In the eyes of these people, it's not weird if it's not pretentious.
Anyway, it’s too outrageous and beyond everyone’s ability to accept...
Lin Tian knew very well in his heart and said lightly without saying much: "Teacher Li, please watch the video."
Li Yan glared at Lin Tian, turned to Wang Wan and said, "Start from this location. From 5 o'clock in the morning the day before yesterday, start checking it for me. Be sure to look carefully and don't miss every corner."
"yes."
Lao Wan responded and immediately started operating.
Snap!
As the sound of the keyboard sounded, the picture on the large screen in the monitoring room began to change. In an instant, the green picture turned into a pitch-black one.
The upper left corner of the video shows the time at five o'clock in the morning the day before yesterday. At this time, the sun has not fully risen. In addition, the jungle is full of dense forests and there is no light at all.
The surrounding jungle is almost static.
However, even if the outside light is very poor, the far-infrared camera, as Li Yan said, can indeed take very clear pictures, even the leaves on the trees.
The working principle of this infrared camera is that the infrared lamp emits infrared rays to illuminate the object, and the infrared rays are diffusely reflected and received by the surveillance camera to form a video image.
Just like using a flashlight to illuminate in the dark night, the flashlight is equivalent to an infrared light, and the camera is equivalent to the human eyeball. The principle is the same. The place where the infrared light shines will light up, so even if there is no light, the picture will be clear.
Moreover, the infrared camera used by the National University of Science and Technology is the kind of camera that can monitor 24 hours a day and night, or a dot matrix infrared camera.
The shooting effect of this dot matrix infrared camera is far better than ordinary ones. The key is that it can also shoot at long distances.
Under such a camera, the overall situation of the back mountain is clearly displayed in front of everyone, without any blind spots.
As soon as the screen started switching, Li Yan stared at the content on the screen intently.
The fun is about to begin, let's see how these guys train.
Going to the back mountain to train is just nonsense. I'm sorry, you guys here have found the wrong opponent.
Tick tock tick…
Two minutes have passed, and the video is still dark and static, almost as if nothing has ever changed. Neither any living creatures nor any human figures can be seen.
Not to mention that 21 people were training there intensively, and not even a single hair was lost.
Swish!
The quieter the scene, the more exciting the expression on Li Yan's face, and in the blink of an eye he revealed a big sneer.
What the hell, training, this is your training scene?
Are you air?
Want to play with me? You guys are a bit green.
Do you think you can hide the truth just by talking nonsense? What a dream!
Li Yan couldn't see any movement in the screen. He turned to look at Lin Tian with a proud look on his face, only to find that this boy had a calm face.
"Isn't there something wrong with his expression? Why doesn't he feel guilty at all? Instead, he seems very calm. Is that right?"
Is this guy's acting skills so good?
Li Yan originally wanted to curse, but when he saw the other person's abnormal expression, he swallowed his words and felt a slight doubt in his heart.
