After Yu Fei discovered the footprints, he immediately stopped, took out his cell phone, and took a few photos of the footprints.

Then Yu Fei stared at the invisible footprints in the dust, relied on his strong vision, and finally found the footprints and walked to the corner of the art room, where debris was piled.

Yu Fei avoided the footprints and walked over, coming to the pile of debris.

Yu Fei looked through the pile of debris and found that there was everything in it, but there was no nail he wanted.

But it was very humid here. Yu Fei looked up along the wall and found signs of water leakage at the top.

Yu Fei knelt down and smelled it, and his eyes widened immediately, because the musty smell here was almost the same as what he smelled in the utility room and on the nails, which meant that the nails might also come from here!

The location where they are located is not a special teaching building, but an office building for teachers. Yu Fei and the others really ignored the office building before. Yu Fei was even misled by himself, thinking that the smell of the utility room was very similar.

I thought the nails would only come from that place!

This is really a huge discovery. Generally, such a teacher's key must be in the hands of a few people, and it must be the teachers who teach art and photography in schools.

Yu Fei left the art room through the window. When he returned to the conference room, the police couldn't find any clues and planned to leave.

"I have made a new discovery! The real source of the nails I found is not in the utility room at all!"

Yu Fei's words made the policeman who was about to leave suddenly become energetic again.

Then Yu Fei told them what he found in the art room. The policemen immediately became energetic and went over to take a look in person. Then they all became excited.

At this time, Ding Taotao provided an important clue!

There is only one teacher who teaches art in the school. Because it is a supplementary subject, it is not taken seriously anywhere. It is good for a school to have only one professional art teacher. In some schools, they just find a random teacher to replace them.

However, after Yu Fei asked about photography, Ding Taotao said that it was a photography corner created by another teacher out of interest, and there were no specialized courses. It was just that she had a good relationship with the art teacher, so she taught privately to students who wanted to learn.

These two people are also among those who have not been excluded!

From the footprints in the classroom, Yu Fei could tell that it was definitely a woman's shoe, and it basically didn't run away now. It seemed that the real culprit behind the scenes was one of these two people!

With so much progress made at once, everyone decided to work together to catch the real culprit behind the scenes!

They quickly went straight to the dormitories of the two teachers. These two people still lived in the same dormitory, which also saved everyone trouble.

It was broad daylight and school had not started yet, so it was easy for them to enter the dormitory building and they went directly to the door of the dormitory.

After knocking on the door, I saw a cute female teacher. She was not very beautiful, but she had a baby face and two small dimples when she smiled. She looked a little shy.

"Teacher Zhao Tiantian, we have something that we need you to cooperate with in the investigation!"

The police walked into the dormitory and immediately stated their intention.

"Ah! Yes!"

The very sweet and cute female teacher named Zhao Tiantian agreed with fear, walked back and sat on the edge of her bed.

Her frightened look made it impossible to tell whether she was naturally timid and shy, or whether she was a murderer and was frightened when the police came to her door.

There is another teacher living in this dormitory, named Zhao Lijuan, who has the same surname as Zhao Tiantian.

Yu Fei only knew her name just now, but when he walked to the other party's table and saw the selfie on the table, he immediately knew who she was.

This Zhao Lijuan was the woman who had just revealed Ding Taotao's background identity two days ago. At that time, she deliberately acted very coldly, but kept peeking at her, trying to get her ideas!

have to say

Most of the women who engage in arts such as fine art photography are not too bad-looking, and they have a certain temperament. Cuteness is a category, and so is aloofness. As for whether it is true or not, it doesn't matter. Adults are all pretending.

"Teacher Zhao Tiantian, have you been to the art room above the office building these days?"

After the police entered the door, they looked at the shoes lying around and asked Zhao Tiantian.

"No, those are the places where students are taught after school starts. I usually draw by myself in the dormitory!"

Zhao Tiantian said fearfully, holding her hands in front of her chest as she spoke, as if these people had some ulterior motive against her.

"Then do you know that Teacher Zhao Lijuan has been there?"

The policeman continued to ask.

"I don't know, she never mentioned it!"

Zhao Tiantian shook her head and said she didn't know.

"Have you ever seen shoes that can leave such footprints?"

The police showed the photographed footprints to Zhao Tiantian.

"These are the footprints of my shoes! But I have never been there!"

Zhao Tiantian was shocked after reading this, her voice was no longer sweet, and she hurriedly defended herself.

"Take out your shoes and look at them!"

The police did not arbitrarily determine that it was the other party, but the suspicion of the other party immediately emerged.

Zhao Tiantian hurriedly rummaged under the bed. Before, everyone could not see clearly because it was covered by the sheets. After lifting up the sheets, everyone found that it was very messy under the bed. There were all kinds of shoes, and they were piled up in confusion. Boots, boots, etc.

Sandals, white shoes, sneakers, high heels, etc. are available in various colors and styles.

But according to Zhao Tiantian's style, high heels and high-waisted boots don't seem to suit her. Could it be that she changes her style according to the pair of shoes?

"These are not just my shoes, but also those of Teacher Zhao Lijuan. Our shoes are placed together, and there are other sundries of ours placed under her bed."

Zhao Tiantian immediately explained embarrassedly.

No one cares about how sloppy a person is under their sweet and cute appearance. This is not a problem that everyone cares about.

Zhao Tiantian quickly found a pair of white shoes from under the bed with a cute pink bow pattern on them.

Comparing the soles with the photos, I found that the pattern on the soles was exactly the same as the footprints taken.

"Are you sure you haven't worn these shoes to the art room? Don't lie. The consequences of lying will be serious!"

A policeman held the shoes and said to Zhao Tiantian very seriously. Seeing her timid appearance, it seemed that she could tell the truth if she was frightened.

But if she is really the mastermind behind the scenes, it's possible, that means she has two sides, and this cute and timid look is just an act!

"No, absolutely not! I bought these shoes last year and only wore them once. They pinched my feet, so I never wore them again!"

Zhao Tiantian hurriedly explained to herself.

"Can Zhao Lijuan wear your shoes?"

Yu Fei suddenly asked.

"Her feet are half a size smaller than mine, so she can wear them."

Zhao Tiantian said quickly.

"Where did Teacher Zhao Lijuan go?"

Yu Fei asked curiously.

"She accompanied the injured teacher to the hospital."

The police did know Zhao Lijuan's whereabouts.

The injured person is a male teacher, and it is appropriate for a male teacher to take care of him. However, a female teacher is so enthusiastic. This is very abnormal.

Moreover, Zhao Lijuan's character is very cold. There is only one possibility for her to follow her to the hospital so eagerly, and that is to disguise herself.

Yu Fei turned around and looked around in the dormitory. Zhao Tiantian didn't say anything because he knew the relationship between Yu Fei and Ding Taotao. Ding Taotao was the victim. As a boyfriend, it was understandable that Yu Fei was anxious, so as long as Yu Fei didn't turn over

She won't say anything about personal items.

The police also looked around. They also knew what Yu Fei was looking for, which was something to drive nails into the ground. Judging from the condition of the ends of the nails, they must be metal objects, stones, bricks, etc. It would definitely not be possible.

Leave a residue on the ground.

Yu Fei was not polite. He would open any cabinet or box he could and take a look.

After searching for a long time, he still found nothing. He also knew that if he searched randomly like this, the chance of finding it was low, or there was a possibility that the other party would not get the item back after using it.

"What are you looking for? Can I help?"

Zhao Tiantian took the initiative and asked.

"A metal object capable of driving nails into cracks in masonry."

Yu Fei didn't hide anything, he stared into Zhao Tiantian's eyes and said.

"I know what is suitable. Zhao Lijuan has a metal figure of a Superman. It has been placed on the bedside. It disappeared today!"

Zhao Tiantian immediately pointed to Zhao Lijuan's bedside and said.

The clue that Zhao Tiantian gave made everyone immediately interested. If Zhao Tiantian was right, then it would be basically certain that Zhao Lijuan was responsible for finding this superman.

Everyone immediately went out in full force, looking for the Superman figure everywhere in the school, looking in weeds, trash cans and other nooks and crannies, but they couldn't find it.

"I understand. The reason why Zhao Lijuan wants to accompany the injured person to the county town is not just to pretend, but also to leave the school and throw the Superman figure further away and somewhere where it is harder to find!"

Yu Fei searched for it and suddenly understood the reason why Zhao Lijuan left with the injured teacher.

If this is really the case, it will be difficult for them to find the Superman figure. It seems difficult to convict just by relying on the shoes, let alone that the shoes belong to Zhao Tiantian.

When they reached a deadlock again, Zhao Lijuan came back. Because the injured teacher's family was here, the teachers who had helped take care of him could naturally leave and come back.

When Zhao Lijuan came in from the gate, Yu Fei saw it at a glance, because this woman had a very special disguised temperament and was wearing black stockings and high heels. Any man would take a second look at her.
