But Dr. Jiang is cold and rusty

Jiang Yi was wearing a loose dark gray t-shirt and black slacks, with his slightly curly mid-length hair loosely tied behind his head, dressed very casually.

She has no makeup on her face, and the only accessory on her body is the black leather watch with a price of more than 100 yuan.

The thin figure only appeared for a moment under the scorching sun, and then flashed into the dilapidated residential building...

The signal in the corridor was extremely poor, and the signal icon was grayed out after Jiang Yi walked a few flights of stairs.

She hadn't thought of being nosy at first, but the man following her stimulated Jiang Yi's nerves. She had always firmly believed that when she realized she was in danger, the best way was to take the initiative.

There was too much dust accumulated in the narrow corridor, which was blown up by a breeze brought by the passers-by, making the air a little choking.

Jiang Yi frowned, taking great care to avoid touching any structures around him. The traditional architectural style of the building reminded Jiang Yi of the place he lived in when he was a child.
She looked up at the wall at the corner of the stairs. The wall was half solid and half hollowed out. It looked very old-fashioned. The sunlight came in directly from the perforation, covered with thick dust particles, illuminating the originally dark corridor. .

The memories of the past made Jiang Yi relax.

However, in an instant, she felt an electric current running through her back, and a strong uneasiness surged into her heart.

She heard footsteps in the lower corridor...

The very slight sound of footsteps made Jiang Yi's hair stand on end. 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 calm...

Jiang Yi didn't dare to turn her head. She kept walking, pretending not to notice, and then took out a "cross" key in her pocket, holding the key handle tightly in her palm, revealing the sharp point on the other side.

The surge of adrenaline aggravated Jiang Yi's nervousness and excitement. She felt her heart beating wildly beside her ears. As the sense of crisis became stronger, under the chaos of her brain, her vision gradually blurred up.

The light from the wall sprinkled on Jiang Yi, projecting her silhouette on the ground, and she saw a shadow that did not belong to her approaching gradually on the cement surface of the steps, which was about to overlap with her own.

Jiang Yi's heart froze, and he turned around violently holding the only iron utensil in his hand.

Looking at the face that jumped into his eyes, Jiang Yi was stunned for a moment, stepped on the ground in a trance, and then rushed forward unstoppably...

The man's eyelids twitched, and he quickly reached out his hand to support the petite figure on the stairs who was stepping on the air, so Jiang Yi looked down on him and hung on the other person's body tightly like a "seamless fit".

Shao Jun raised his eyebrows, only to feel the woman's loose long hair covering his face, making him take a mouthful of the fragrance of jasmine,

"Is Dr. Jiang throwing himself at me?"

Jiang Yi bounced off him like an electric shock, his face flushed with embarrassment in an instant:

"You... why are you here?"

Shao Jun didn't answer, but asked instead:
"What is Dr. Jiang doing here?"

In fact, both of them are well aware that they are suspicious of each other. Not long ago, the incident of the truck driver jumping off the top floor of this apartment building and falling bloody and bloody seems to have passed, but the doubt has been lingering in his heart for a long time. Not scattered, it is difficult to turn a blind eye.

However, this matter is entirely Shao Jun's private matter, and he should investigate it himself. He doesn't know why Jiang Yi showed such 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, so why did she make him misunderstand and think too much?
Jiang Yi walked upstairs, not noticing that the people behind her were standing there with mixed emotions, the stairs under her feet were narrow and short, and she reached the top floor in a short while, standing in front of a red rusty iron door.

　The door on the rooftop has signs of being cut off. The lock that has been abandoned for many years is rusty, and the break looks relatively new in comparison, probably it was split not long ago.

The iron gate was opened when Wang Xin jumped off the building, but the police did not mention this kind of tool that can saw through the iron lock when they were investigating the scene at that time, so this matter was not done by Wang Xin, unless he was hacking. After locking it, he secretly hid the tools in his hand elsewhere, but he was so depressed that he committed suicide, it seemed unnecessary to do so.

Perhaps the matter of the iron gate had nothing to do with Wang Xin. Somebody had no key and had to go to the roof to break the door lock with a tool. However, this old residential building was never visited by anyone. Who could it be?
However, there is another possibility that when Wang Xin jumped off the building, there was another person who opened the door and took the tools in his hand when he left.

Jiang Yi felt that his idea was a bit mysterious, but it seemed that it was not impossible. After all, the most troublesome part of finding out this matter was that this residential building had no residents and no surveillance.

If the other party had acted cautiously enough, there might not have been fresh fingerprints on the door other than Wang Xin, and it was impossible for her to make the police re-examine this suicide case that had already fallen to the ground just by guessing.

"What are you looking at?"

Shao Jun suddenly uttered a word close to his ear, as if blowing into his ear, Jiang Yi frowned, and subconsciously dodged aside, almost hitting a row of brooms and dustpans piled up in the corner,
"What are you doing!"

Seeing a look of panic flashing across Jiang Yi's usually calm face, Shao Jun smiled lightly:
"Doctor Jiang, don't be nervous, I'm just curious." After speaking, he added with a particularly awkward expression:
"Also, I think Dr. Jiang is very cute when you are distracted."

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

Jiang Yi stepped up the steps and walked up to the roof of the open-air building. The scene of the roof was very dilapidated. Some exposed reinforced concrete, she suddenly felt a little scared

...This old building in its dying years won't collapse suddenly, right?

Purple and pale pink morning glories entwine on the dilapidated wooden flower stands, which seem to be the only life in the dead and desolate scene, and there is no sign of any human habitation here.

Jiang Yi suddenly walked to the fence, looked down from the top of the building,

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