"Oh, wear this one too, just in case." Ji Yun took out two dust masks from his pocket and handed them to Shen Cangcang.

Shen Cangcang looked at the black mask and couldn't help but be a little strange: "Do you usually carry this thing with you?" ”

"I have bad lungs and always cough." Ji Yun explained.

After speaking, Ji Yun had already walked towards Deng Sheng's old mansion.

The old house had a small fenced yard covered with vines, as if it had been left untended for some time.

The yard is quite messy, what cartons, foam, boards, it can be seen that Deng Sheng often buys some strange things online.

The old house is actually very good, and it can even be turned into a coffee shop with a little literature and art, but it is made like a deserted house, and it will really refresh Ah Piao in the middle of the night.

"This Deng Sheng is usually glamorous, but he lives in the same place as a kennel." Ji Yun scolded as he walked.

But that's fine, if it's so messy, it means that most of his house doesn't have many people to live in, and maybe even Deng Sheng alone.

Ji Yun was not in a hurry to go inside, he looked around the perimeter of the fence wall, and posed as if he was looking for a cat.

When he was learning to pick locks from Master Li, Master Li also taught Ji Yun some tips for investigation by the way.

For example, if you look at clothes from the windowsill, especially underwear, you can tell how many people live in the room, whether they are men or women.

If you can see the shoe rack, then to judge when the owner of the house usually goes to work and when to leave work, many people will put the shoe rack outside the house......

And if you don't dislike hiding, you can also go to double the nearby trash cans, and even the owner's three meals, daily habits, and personal preferences can be clearly checked.

Ji Yun didn't know why Master Li wanted to teach him these strange skills, so Ji Yun just listened to it when he was studying, and now it came in handy.

"Alright, let's go." After Ji Yun finished the exploration of the periphery, he opened his mouth and said to Shen Cangcang.

"But you didn't even go in?" Shen Cangcang said in surprise.

"Just check outside, for safety reasons, I'll go in next time." Ji Yun said.

Shen Cangcang looked like he was still unsatisfied, he had obviously found the den, and he was uncomfortable if he didn't go in to see it.

However, Ji Yun had already retreated, and Shen Cangcang could only leave in a huff.

……

Ji Yun must be cautious.

He and Shen Cangcang are both just high school students, but they may be facing an illegal gang entrenched in Lancheng.

In the early stage of work, Ji Yun can prepare sufficiently, and then thunder when it is implemented, to ensure that it can hit the nail on the head and achieve immediate results.

At the very least, it must be able to deal a devastating blow to Deng Sheng.

Riding a small electric stove again, he drove Shen Cangcang to Deng Sheng's dilapidated old mansion.

Ji Yun has already determined that Deng Sheng is the only one living in this house, and he has lived alone for a long time.

"Cat cat lend me." Ji Yun said to Shen Cangcang.

"What?" Shen Cangcang wondered.

Ji Yun picked up the cat and put it in the fence yard.

The little wild cat was really human, and it immediately jumped into the messy courtyard, and even went straight to the other party's house.

"Good way, too." Shen Cangcang's eyes lit up immediately, he didn't expect this boy to be so smart.

"You're watching from the outside, and someone is coming, be sure to notify me." Ji Yun said to Shen Cangcang.

"No problem!" Shen Cangcang said with a little excitement.

Finding the dens of illegal gangs is much more fun than taking a class!

Ji Yun followed the kitten into the old mansion.

This is an old house on the second floor, walking into the hall, the room should be upstairs, the first floor is the kitchen and an old man's room.

The old man's room is very empty and clean.

There is nothing in the kitchen, which shows that Deng Sheng is also a takeaway maniac.

There was nothing to see on the first floor, and Ji Yunjing went to the second floor.

There were a total of three rooms on the second floor, and Ji Yun had roughly figured it out from the outside.

Ji Yun focused on the room with closed windows and strict blackout cloth, if you need to store some strange medicines, it is necessary to be cool.

Masks, hats, gloves, Ji Yun is quite well equipped, and Master Li even told Ji Yun that it is necessary to wear a pair of ill-fitting shoes when traveling.

But Ji Yun felt that this was too much, he was punishing evil and promoting good, keeping up with the Chaoyang masses, and not making it more difficult for his uncles to solve the case!

Of course, Ji Yun can also ensure that he will not leave a single hair in his hair.

It's also strange to say that when he was learning various knowledge in the library, Ji Yun didn't know how many times he used it, but when he went to Master Li, he didn't repeat it many times, but he quickly mastered this craft!

took out the lockpicking tool, Ji Yun is now considered professional-level, and he can open the door without breaking the lock cylinder.

"Click!"

The door was easily opened, and Ji Yun's whole process took less than 10 seconds.

Looking at the revolving door lock that left no traces, Ji Yun understood why when he went back to school, Master Li's eyes were always a little reluctant.

It turns out that I am really talented in this area!

Pushing the door in, Ji Yun found that it was just an old-fashioned study, and there was nothing in it.

Ji Yun unwillingly searched inside, but still found nothing.

In desperation, Ji Yun had no choice but to search in another room.

There are two rooms, one is a pile of clutter, and the other is Deng Sheng's bedroom.

His bedroom was scruffy and messy, with worn clothes, cigarette butts, smelly slippers, and some bizarre drink jars.

In fact, from the cleanliness of a person's room, you can basically judge a person's self-discipline, and the place where Deng Sheng sleeps is really not an ordinary mess.

If it's a kennel underneath, it's a pig's kennel above, and the whole room smells sour.

Looks like a dog to outsiders, but it is revealed in his own home!

Ji Yun rummaged through the ...... while disgusting

It's a pity that there is still no gain!

"The direction is wrong, could it be that this guy is a second-class dealer, hoarding drugs to sell elsewhere at a high price?" Ji Yun suddenly felt a little disappointed.

Deng Sheng has nothing at home.

And from the trash can near him, Ji Yun could tell that after Deng Sheng finished work, he spent most of his time nesting in this pig's nest.

He should not have a secret base.

Could it be that it was in that night club?

But it's obviously outside of your own borders, unless you can unlock time and expand your activity boundaries.

If you're there, you'll be helpless!

Ji Yun thought about it and checked at the same time, so as not to leave some traces that Deng Sheng would detect.

Dealt with the bedroom and inspected the old den again.

Suddenly, Ji Yun realized something.

If this is a study, why is the door locked?

Deng Sheng lives alone, the outside door is locked, and the hall door is locked, all of which can be understood, why lock a study, is it possible that someone still runs here to steal books?

Ji Yun stopped leaving, and once again carefully searched the study.

"The rest of the place is like a pig's nest, why does this study look spotless??" Ji Yun immediately sensed this problem again.

Sloppy and lazy, this is Deng Sheng's nature, and he should do whatever he wants in his own house, and he doesn't need to take care of it.

Why is he so "in awe" of this study, just like he is out of the house and behaves so well-dressed in the workplace? ?

What's so special about this study???

Ji Yun realized this, and he was sure that there was something wrong with this study.

Such a thick blackout cloth, and no medicine is stored, obviously it is just to put some books, why not let the sun in?

Ji Yun walked to the window and lifted the corner of the blackout cloth, letting the sunlight shine in from outside the house.

Because of the eclipse day, the light was particularly enchanting, and the golden glow with some crimson light broke through the window, illuminating the gloomy study......

As Ji Yun moved, the light and dust rose up, like a long curtain of gold sand, hanging obliquely on the bookshelf.

Ji Yun glanced at the foot of the bookshelf, and there was no trace of moving.

However, when he squatted down to check, Ji Yun found a relatively new book.

Most of the books in this room are very old, and some of them are left by Deng Sheng when he was a student, but under this bookshelf there is a brand new book, not even dust......

Sunlight is really a good thing, and it makes a lot of things visible!

Ji Yun looked at this book carefully, in other words, ordinary people would not have any feelings about such a book on chemical pharmacology, it was really that Ji Yun had been on the shelves in the library for too long, and the packaging and appearance of this book were clearly from that series!

It's the one the chemistry teacher with glasses was looking for!

About ephedrine!!

Got it.

This book is really in Deng Sheng!!

He hoarded a large number of ephedrine medicines in his position, and then read books on ephedrine and ice products.

The two are separated, the former can be explained by the fact that there are many students in the flu season, and the latter is alone, and it can also be explained by the fact that he is studying medicine and understands medication and anesthesia, but when the two are combined, it is a big hopeful problem!

This guy already has the elements of punishment!!

"It must be in this room, it must be somewhere I didn't find out!!" Ji Yun couldn't help but get excited in his heart.

On the one hand, the hatred of opium engraved in his bones, and on the other hand, he found the key to breaking the game, Ji Yun had a hunch that this Deng Sheng must have done something illegal!!

Wait for Deng Sheng, you are dead!

You foul-smelling school doctor, director of the foul-smelling equipment department!!

Let the students donate blood and take a lot of kickbacks themselves.

The persecution of Vice Principal Wang made the school a miasma.

Privately renting hospital equipment to private hospitals, so that real patients in the hospital can't breathe!

Although Ji Yun had never had any direct contact with Deng Sheng, he had already felt the stench and shamelessness of this guy, and he couldn't wait to give him a kick in the face of Sven scum!
