Jiang Yi was wearing a loose dark gray shirt and black slacks, and her medium-long hair with slightly curly ends was loosely pulled behind her head, and she was dressed very casually.

She didn't wear makeup on her face, and the only accessory on her body was the black leather strap watch in her hand that cost more than 100 yuan.

The lean figure appeared only for a moment in the hot sun, and then flashed into the dilapidated residential buildings......

The signal in the corridor was extremely poor, Jiang Yi didn't take a few stairs, and the signal icon was gray.

She hadn't thought of meddling in her own affairs, but the man who followed her stimulated Jiang Yi's nerves, and she had always believed that when she realized that she was in danger, the best thing to do was to take the initiative.

There was so much dust in the narrow corridor that the air was choking when it was stirred up by a breeze that came with it as it passed.

Jiang Yi's eyebrows were furrowed, and he was very careful to avoid touching any buildings around him, the traditional architectural style of the building reminded Jiang Yi of the place where he lived when he was a child.

She looked up at the wall at the corner of the staircase, half solid and half hollowed-out, looking very old, and the sunlight shining through the perforations, wrapped in heavy dust particles, illuminating the otherwise gloomy corridor.

The memories of the past made Jiang Yi relax.

However, in an instant, she felt as if a glimmer of electricity rushed through her spine, and a strong uneasiness surged over her heart.

She heard footsteps in the hallway below......

A very slight sound of footsteps made Jiang Yihan stand up, and this fleeting sound indicated that someone had walked into this residential building, but was deliberately hiding his whereabouts.

She felt a strange aura approaching step by step, but she remained silent......

Jiang Yi didn't dare to look back, she didn't stop, pretending not to notice, and then took out a "cross" key in her pocket, and held the handle tightly in her palm, revealing the sharp tip on the other side.

The adrenaline rush aggravated Jiang Yi's nervous and excited emotions, and she felt that her heart was beating violently in her ears, and as the sense of crisis became stronger and stronger, under the chaos of her brain, her vision gradually blurred.

The light through the wall sprinkled on Jiang Yi's body, projecting her silhouette on the ground, and she saw that on the cement surface of the steps, a shadow that did not belong to her was gradually approaching, and it was about to overlap with herself.

Jiang Yi's heart was horizontal, and he turned around violently with the only iron utensil in his hand.

Looking at the face that jumped in front of him, Jiang Yi was stunned for a moment, stepped on the air in a trance, and then rushed forward unstoppably......

The man's eyelids jumped, and he reached out to support the petite figure on the stairs with one foot in the air, so Jiang Yi was condescending and hung tightly on the other party like a "seamless fit".

Shao Jun raised his eyebrows, only to feel that the woman's long hair was scattered and covered his face, and he took a mouthful of jasmine fragrance.

"Is Dr. Jiang throwing a hug on me?"

Jiang Yi bounced off him like an electric shock, and suddenly his face was red with embarrassment:

"You...... Why are you here? ”

Shao Jun didn't answer, but asked rhetorically:

"What is Dr. Jiang doing here?"

In fact, both of them know what they are suspicious of each other, not long ago the truck driver jumped from the top floor of this unit building and fell bloody and bloody seems to have passed, but the suspicion lingers in their hearts for a long time, making it difficult to turn a blind eye.

However, this matter is completely Shao Jun's private matter, and if he wants to investigate, he should investigate it himself, he doesn't know why Jiang Yi showed strong interest and ran to this residential building in a grand manner.

She hates herself so much, why would she want to find out the truth of this matter for herself?

What was she thinking in her heart, Shao Jun didn't understand, she obviously didn't care, why did she let him misunderstand and think about it?

Jiang Yijing walked upstairs, not noticing that the person behind her was standing in place with a complicated mind, the stairs under her feet were narrow and short, and in a few moments she reached the top floor, standing in front of an iron door full of red rust.

The door on the rooftop has traces of being cut off, and the locks that have been discarded over the years are rusty, and the fracture is relatively new in comparison, probably split not long ago.

The iron door was opened when Wang Xin jumped off the building, but this kind of tool that can cut the iron lock was not mentioned by the police when they surveyed the scene at that time, so this matter was not done by Wang Xin, unless he secretly hid the tool in his hand somewhere else after splitting the lock, but he is a person who is so depressed that he commits suicide, and it seems that there is no need to do this.

Maybe the matter of the iron door has nothing to do with Wang Xin, who has no key and has to go to the roof of the building to break the door lock with a tool, but this old residential building is not visited at all on weekdays, who will this person be?

However, there is another possibility, that is, there was another person when Wang Xin jumped off the building, he split the door, and took the tools in his hand with him when he left.

Jiang Yi felt that his thoughts were a bit mysterious, but it seemed that it was not impossible, after all, the most troublesome place to find out about this matter was this residential building, there were no residents, and there was no monitoring.

If the other party acted cautiously enough, there would not necessarily be fresh fingerprints on the door except for Wang Xin, and she would not be able to make the police re-examine this dusty suicide case just by guessing out of thin air.

"What are you looking at?"

Shao Jun suddenly put a sentence in his ear and spit out a sentence, as if he was blowing on his ear, Jiang Yi twisted his eyebrows, subconsciously dodged to the side, and almost hit a row of broom dustpans piled up in the corner,

"What are you doing!"

Seeing a look of panic flashing on Jiang Yi's always calm face, Shao Jun smiled lightly:

"Doctor Jiang, don't be nervous, I'm just curious." After speaking, he added with a particularly under-pumping expression:

"Also, I think Dr. Jiang, your distracted look is very cute."

The inexplicable man in front of her seemed to be very keen on teasing herself, Jiang Yi couldn't help clenching her fists, she now wanted to seal Shao Jun's rotten mouth with a piece of adhesive strip.

Jiang Yi stepped up the steps and walked on the top of the open-air building, the scene on the rooftop was very desolate, the cracked ground was almost burning a cluster of fire under the scorching sun, and some bare reinforced concrete was washed out by the wind and rain for many years, and she was suddenly a little scared

…… This old building won't collapse suddenly, right?

Purple and pale pink morning glories twinked around the ruined wooden trellises seemed to be the only shred of life in the bleak sight of the moment, and there was no sign of any human being here.

Jiang Yi suddenly walked to the fence and looked down from the roof,

Standing on the rooftop on the sixth floor, she wondered, what kind of person would have the urge to jump?
