"The fire started on the 23rd floor, according to the head of the household, recently there were rashes one after another in the house to avoid infecting the children, so the whole house was disinfected with alcohol every day, it may be too dry, and the fire broke out as soon as the air conditioner was turned on last night."

"Turning on the air conditioner and causing a fire?" Su Jin paused. "Even if the alcohol content in the air is high, it will not be ......"

"Because yesterday afternoon, the people from the air conditioning company came to clean the air conditioner, and the heating mode was turned on, and the central air conditioner caught fire, and the entire pipe was burned, and it was too late to extinguish it." These are the exact words of the head of the fire brigade.

Su Jin shook his head: "The odds are too low......"

But it's not impossible.

She continued to walk up, "The explosion was also on the twenty-third floor, what reason?" ”

"Natural gas leaked, causing an explosion."

"It took so long to leak? And in the absence of a source of fire? "Su Jin always thinks it's too much of a coincidence, why did it all happen on the twenty-third floor?

"Do you think it's suspicious?"

"You don't have any doubts?" She asked rhetorically.

Shan Chenxun rubbed her hair and said with a smile, "There are many doubts." ”

They quickened their pace, and ten minutes later they reached the twenty-third floor.

This floor burned the hardest, the walls of the stairwell were all black, the security doors were blown up, and the ground was littered with rubble.

"Be careful." Shan Chenxun reminded the two women.

Yuan Ke held a flashlight and entered the corridor, Su Jin shone the safety door with a flashlight, she walked forward slowly, and kept looking around.

The air in the hallway was muddy, the walls were charred black, there was only one house on this floor, and the double door had been blown up.

The three of them entered the house one after another, and the living room was in a mess, and the sofa and dining table could no longer be seen in their original appearance.

Especially the air conditioning outlets, the pipes were melted by the fire, and the whole house was devastated.

"Let's go to the kitchen." Su Geun said.

Shan Chenxun followed her to the kitchen, where she crouched down, stared at the natural gas pipe under the cupboard, and carefully photographed it with a flashlight.

"Look......," she gestured to Shan Chenxun.

The man approached and looked at the valve of the pipe, Su Jin touched it gently, and there was only a little black ash on the glove.

"It's cleaner than anywhere else." Shan Chenxun stared at the light ash on her fingers, and it was obvious that some of the ash on the valve switch had been wiped off.

"Someone should have moved the valve after the fire or after the explosion."

"Well, if it's not the firefighters who moved, then this person is very problematic." Shan Chenxun got up and looked at the entire kitchen.

Since it has been burned beyond recognition, there is nothing unusual to see.

Yuan Ke took a picture of the valve, and the three of them walked around each room before continuing upstairs.

The top floor is brightly lit, and a cordon is pulled from the elevator.

The scene remained as it was, with Su Jin and Shan Chenxun standing on the staircase, looking at the dried blood stains on the glass.

"The area of the first layer is relatively large, I judge that it should be the blood of the deceased, she is bleeding from the large arteries in the neck, and the amount of blood is naturally more......" Su Jin pointed to the glass, "The second layer is a splash of blood, there are not many blood stains, only dozens of drops." ”

"Well, it should be the blood of the second person, and as for the third person......" He frowned, and there were no three traces of blood visible to the naked eye.

Su Jin walked up and looked at the blood stains on the glass in the hallway, which were about the same as those on the stairs.

Entering the master bedroom, the smell was very fishy, probably the reason for the closed window, and there was a strange smell in the air, and I couldn't tell what it was.

"Do you smell anything?" She looked at Shan Chenxun.
