My Sister is Too Protective

After resting for a while, Chen Hu was still sent to the hospital for examination.

Lin Feng first went back to the basement and observed it carefully.

Sure enough, it was almost what he thought.

Some hair strands tied in a straight line were found at the door, as well as a toothpick and an empty capsule.

These things are hanging at the front door. As long as someone comes in, the hair will be pulled off by the door, and then the powder in the capsule will be poured out, which is an illusion.

The overhead lamp has also been tampered with. The bulb is coated with a layer of medicine that will quickly volatilize after heating. As for why it will go off, one of the tungsten wires is broken.

There is another discovery that the ventilation ducts in the basement seem to have been moved by people, because this place is a large shopping mall. Considering the problem of heat dissipation, the ventilation ducts are deliberately made very large.

So let an adult get in and then quietly so let an adult get in, and then quietly escaped here.

Seeing this, Lin Feng couldn't help but sigh secretly, this person's mind is really meticulous.

After checking the basement and confirming that there were no other goods received, I arrived at the monitoring room.

In the surveillance picture, the man guarding the door, who was standing well, suddenly yelled as if he had seen something, and then gradually talked and laughed.

Immediately after that, he made a series of indescribable actions, and then reached out his arm around the waist of an invisible person and walked out of the monitoring screen.

Half an hour later, the man came back again, and after a while, it was Gu Lan and others who arrived, and Lin Feng arrived soon after.

Seeing this, Gulan pressed the pause button.

"I watched it several times and I didn't see it. What is going on, or should we ask someone from the relevant department?"

Lin Feng chuckled lightly.

"Come on, be careful that you are sentenced to illegal detention."

After Gu Lan listened to it, he couldn't help but pouted, and put his hands around his chest.

"Then you tell me what the **** is going on!"

"Well, don't be angry, let me explain to you."

With that said, I adjusted the monitoring screen back to the beginning.

Almost everyone didn't notice. At that time, a gust of wind blew over.

Because Lin Feng discovered that the hair of the person standing at the door shook slightly.

Combining with the ones just found in the basement, Lin Feng felt that the guy probably used this gust of wind to spill the hallucinogenic drugs, causing the man to hallucinate.

After the hallucinations, he left the monitoring screen for half an hour, and half an hour later, he returned by himself.

Judging from the monitoring screen, it was indeed a person who came back, but as long as you observe carefully, you will find that this person's feet are big for a while and small for a while, and the shadow behind him is also a little strange.

After the person stood back to their original position, some shadows appeared next to them, and then disappeared quickly.

Lin Feng guessed that this was definitely because the person hid behind the man from the beginning, evaded the surveillance probe in this way, and entered the basement.

After entering the basement, he used the key of the person standing outside to unlock the lock on A Lang's body and let him run out.

Gu Lan was thoughtful when he heard this.

"Then what you said, seems to have seen that person in the basement, what's the situation?"

Lin Feng frowned slightly.

"I'm sure that the person I kicked last is real, not my illusion."

After thinking about the scene carefully, he said again.

"The position where we were standing was still some distance from the outlet of the ventilation duct. It was absolutely impossible for that guy to escape from there in such a short time."

First, there is a high distance between the air outlet and the ground. Unless it is a professional athlete, it is absolutely impossible to jump to that position by jumping, and even if it can be done, it will definitely make a sound.

Second, everyone rushed in from the outside at the time, and everyone was holding flashlights in their hands, and the entire basement was illuminated clearly. If a strange person is found, they will be seen the first time.

In summary, Lin Feng had a bold idea.

"If I didn't guess wrong, that person actually didn't escape from the beginning."

"What do you mean?"

Lin Feng took a deep breath.

"Let's watch the monitoring."

Return the monitoring screen to when Gu Lan took the people to the corridor.

Lin Feng counted them carefully, and with Gu Lan, there were a total of eight people.

Then fast forward until everyone came out of it, and eleven people appeared on the monitoring screen.

After pressing the pause button, Lin Feng turned to look at Gu Lan.

"One more person."

Gu Lan frowned, and after comparing back and forth, he found that there was indeed one more person, but after thinking about it carefully, he couldn't remember who was more.

Because everyone was wearing the same clothes at the time, and the height and body were not much different, it was difficult to recognize.

After doing several comparisons back and forth, Lin Feng circled one person.

The man looked unremarkable, with a popular face, which made it difficult to remember his looks.

But after seeing it, Gu Lan was taken aback.

"I seem to have an impression of this person."

"He came to sign up before, and I think he often comes here, but he hasn't talked to him much. Wait, I'll look for his information."

After speaking, he ran out without listening to Lin Feng's words.

Soon, Gu Lan walked in with a large pile of materials.

"This is the information of all the students who signed up during this time, and this guy's information must be in it."

As Gu Lan spoke, he flipped quickly.

"As long as we find this guy's information, we might be able to find some clues along the way. We found it, here."

Take one out of it and hand it to Lin Feng.

Lin Feng took it smoothly, just took a look after opening it, and then unfolded it and showed it to Gu Lan.

When he first saw the content on it, Gu Lan felt a little bit in his heart.

"This... how could this happen? Why is there nothing?"

Except for one photo, all the information is blank.

Lin Feng shrugged.

"Just now I asked you to stop working and you didn't listen. How could a person with such a careful mind leave any clues?"

Gulan suddenly realized.

"I see! He must have used a pen that will disappear automatically, so these materials will not be seen, but as long as it is frozen in the refrigerator for a while, or it is slightly baked on the fire, the original writing will be lost. Resurfaced."

After speaking, pick up the information and leave.

Lin Feng quickly grabbed her.

"Okay, Miss Gu, don't be busy."
