My senior sister is too protective

Chapter 275
Chapter 295
After resting for a while, Chen Hu was sent to the hospital for examination.

On Lin Feng's side, he first went back to the basement and observed carefully.

Sure enough, it was almost the same as he thought.

Some strands of hair tied in a straight line were found near the door, along with a toothpick and an empty capsule.

These things are hung at the main entrance. As long as someone comes in, the hair will be broken by the door, and then the powder in the capsule will be poured out. This is a hallucination.

The lamp above the head was also tampered with. The bulb was coated with a layer of medicine that would evaporate quickly after heating. As for why it went out, it was because one of the tungsten wires was broken.

Another discovery was that the ventilation ducts in the basement seemed to have been tampered with. Because this place is a large shopping mall, the ventilation ducts were specially made very large in consideration of heat dissipation.

So let an adult get in and sneak out of here.

Seeing this, Lin Feng couldn't help sighing secretly, this person's thoughts are really meticulous.

After checking the basement to confirm that there were no other goods received, they arrived at the monitoring room.

In the surveillance screen, the man guarding the door, who was standing still, suddenly yelled loudly as if he saw something, and then gradually talked and laughed.

Immediately afterwards, he made a series of indescribable movements, and then walked out of the surveillance screen with his arms around the waist of an invisible person.

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 not long after.

Seeing this, Gu Lan pressed the pause button.

"I looked at it several times but didn't see it. What's going on, why don't we ask the relevant departments?"

Lin Feng chuckled lightly.

"Come on, be careful that someone will sentence you to illegal detention."

After hearing this, Gu Lan couldn't help but pouted and folded his arms around his chest.

"Then tell me what's going on!"

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

As he said that, he adjusted the monitoring screen back to the beginning.

Almost everyone didn't notice that there was a gust of wind blowing over at that time.

Because Lin Feng noticed that the hair of the man standing at the door shook slightly a few times.

Combined with what he just found in the basement, Lin Feng felt that that guy probably took advantage of the gust of wind to spill out the hallucinogenic drugs, thus causing the man to hallucinate.

After hallucinating, he left the monitoring screen for half an hour, and half an hour later, he came back by himself.

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

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

Lin Feng guessed that this was definitely because the man had been hiding behind the man from the very beginning, using this method to escape the surveillance probe and enter the basement.

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

Gulan was thoughtful when he heard this.

"Then you said that you seem to have seen that person in the basement, so what happened?"

Lin Feng frowned slightly.

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

After carefully recalling the scene at that time, he said again.

"At that time, there was still some distance between where we were standing and the air 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 long distance between the air outlet and the ground. Unless it is a professional athlete, it is absolutely impossible to climb to that position by bouncing, and even if it can be done, it will definitely make a sound.

Second, everyone rushed in from the outside at that time, and everyone had flashlights in their hands, and the entire basement was illuminated brightly. If there were any strange people, they would be seen immediately.

To sum up, Lin Feng had a bold idea.

"If I'm not 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 led the people to the corridor.

Lin Feng counted carefully, including Gu Lan, there were eight people in total.

Then fast forward to when everyone came out from the inside, and eleven people appeared on the surveillance screen.

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

"There is one more person."

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

Because everyone was wearing the same clothes at that time, and their heights and shapes were not much different, it was difficult to identify them.

After going back and forth several times for comparison, Lin Feng only circled one person.

That person looked ordinary, with a popular face, which made it difficult to remember his appearance.

But Gulan was taken aback when he saw it.

"I seem to have a little impression of this person."

"He came to sign up before, and I also saw that he came here often, but I haven't talked to him much. Wait, I'll look for his information."

After finishing speaking, he didn't listen to what Lin Feng said later, and ran out in a hurry.

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

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

As Gulan spoke, he flipped quickly.

"As long as we find this guy's information, maybe we can find some clues along the way. We found it, here."

He took out one and handed it to Lin Feng.

Lin Feng took it and opened it, just glanced at it, then unfolded it and showed it to Gu Lan.

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

"This... how can this be? Why is there nothing?"

Except for one photo, everything on the information is blank.

Lin Feng shrugged.

"I told you to stop busy just now. If you didn't listen, how could a person with such a thoughtful mind leave any clues?"

Gulan suddenly realized.

"I see! He must have used a pen that disappears automatically, so these materials will disappear, but as long as you put it in the refrigerator for a while, or put it on the fire for a while, the original handwriting will disappear. resurfaced."

After speaking, pick up the materials and leave.

Lin Feng quickly grabbed her.

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