The next morning, the laboratory of the Fire Investigation Department came out of the results. The molten glass that Gong Yingxian picked up at the scene was like his speculation, from the alcohol lamp.

Ren Yi asked Qiu Wen to send a report to Hongwu Branch, and then sent a message to notify Gong Yingxian of the results of the inspection.

With such conclusive evidence, the case can basically be closed. It has only been four days since the inception. With such efficiency, you should be able to explain it to the leaders and the public.

Ren Yi thought the matter was over, but at dusk, he received another call from Gong Yingxian.

“Have you received the inspection report?”

"I received it, I want to confirm something with you." Gong Yingxian said.

"What?"

"From the time when you receive the report of Harmony Police, to the scene, to the opening of the emergency passage, to the fire extinguishing, these are the exact time points."

"I haven't finished writing the report yet, so I can send it to you first. There are detailed records in it. What's wrong?"

“The case may change.”

Ren Yi sat upright and said, "What changes? Can't the case be closed?"

"Cai Wan admitted to absorbing harmony poison, and admitted that it was the alcohol lamp that ignited the sofa, but she said that there were other people in the box, strange men, who were confused and could not remember the other person's appearance. She said that the person deliberately broke the alcohol lamp. She didn't dare to say it because she was afraid of being discovered to absorb harmony poison."

Ren Yi was silent for a moment: "Do you believe what a person who absorbs harmony and poison says? Her words have changed several times."

"Everyone who absorbs harmony and poison has a fraudulent personality. I won't believe her completely, but there is a bit suspicious. The bottle mouth of the alcohol lamp has a sealed design. If it is just poured, the cotton core will leak, but it is difficult to cause large-scale leakage at once. Moreover, the bottle body is generally thicker. How high is the coffee table or sofa from the ground? About 40 cm, I bought seven different alcohol lamps and tried it. The height fell to the ground. Only one of the worst quality broke. The one I picked up was thicker."

"Creating such a fast, unsufferable combustion requires more combustion aids. You mean, someone might have broken the bottle with force."

"Cai Wan said so too. Of course, this does not rule out the possibility that she broke, but I just need more evidence to prove it." Gong Yingxian paused, "or deny it."

"How do you want to prove it?"

"I want to return to the scene during the crime time to see if there are new clues."

"Go tonight? The light is not good."

“Restore the scene as much as possible, which helps to think from the perspective of the criminal.”

Ren Yi grabbed his hair: "Okay."

----

At around 1:00 in the evening, the two of them came to the fourth perspective again.

Such a big accident happened here a few days ago, and the business was naturally affected. At this time, the whole street was quite cold and no longer as lively as before.

When he arrived at the scene, Gong Yingxian did not rush in, but walked the street twice, leading the east and west sides to the fourth perspective.

Ren Yi followed him to the road, smelling the fragrance coming out of the restaurant, and his mouth and tongue produced fluid, and his stomach was thrust hard.

It was not until after midnight, about the time before the fire broke out, the two of them crossed the seal and came to the ruins.

Gong Yingxian took a deep breath, put on a mask, and turned on the flashlight.

"Wait a minute." Ren Yi looked at him, "You won't vomit anymore, are you?"

Gong Yingxian said: "No guarantee."

"It's just a little dirty here, and you'll vomit. Have you ever seen a psychologist?" Ren Yi shrugged, "Since that's the case, why bother yourself."

Gong Yingxian said coldly: "If you talk less nonsense, we can end it sooner, maybe I won't vomit on you." After that, he took a big step in.

Ren Yi glanced at him and followed him in.

This place is no different from the previous two days, but the sight is very poor at night, so they must always pay attention to their feet, otherwise they will easily trip over all kinds of things.

The two of them fumbled upstairs. Gong Yingxian checked other private rooms and murmured: "The door of the private room is closed, and there is no situation inside from the outside. If what Cai Wan said is true, there are so many private rooms here, why did that person enter them and why did he set fire?"

"I still think she is lying. The person she is talking about may not exist at all, or she is sheltering someone she knows." Ren Yi said "tsk", "It's true that she is alive and there is no evidence to die."

Gong Yingxian did not comment and walked towards the second floor while looking.

Ren Yi suddenly thought of something: "Hey, do you think the bar owner knows that someone is sucking harmonious poison in his bar?"

"This is a good question." Gong Yingxian said, "My colleagues are investigating."

"A young girl is just a poisonous harmony product." Ren Yi sighed.

"Too many. Cai Wan said she hadn't used it a few times. This synthetic poison-like harmony product has a great nerve damage. Her confusion may not be entirely because of lying."

"By the way, are you really a PhD in chemistry?"

"Um."

"Then you can synthesize it yourself like on TV...you know."

"Just a simple chemical operation."

Suddenly, a slight creaking sound came from behind the two of them. They all turned around and saw a black shadow flashing behind them.

In the middle of the night, when he saw such a fake shadow in a building with nearly thirty people dead and burned beyond recognition, Ren Yi suddenly felt goosebumps and stood up.

"Who!" Gong Yingxian roared and chased after him like an arrow.

Ren Yi also quickly followed.

The figure ran through the long corridor and rushed towards the stairs.

After Ren Yi confirmed that he was a living person, he breathed a sigh of relief, but he did not slacken for a moment. One of the common characteristics of arsonists is that he likes to return to the scene and recall his "masterpiece" over and over again. This person is likely...

Suddenly, Gong Yingxian, who was running in front, tripped by something and fell forward. Ren Yi couldn't stop and hit him. The two of them rolled into a ball in the messy ruins.

Ren Yi felt something hitting his ribs and twisted his feet, which made him scream in pain, and Gong Yingxian's breathing sound came from his ears.

The smell of Gong Yingxian's body plunged into Ren Yan's breath. It turned out that the faint, dry and textured herbal smell was not only on Gong Yingxian's car, but also on his body...

Gong Yingxian pushed Ren Yi aside, jumped up from the ground, and said sternly: "Stop!"

Ren Yi looked up and saw that the person they were chasing had already gone down the stairs.

Gong Yingxian threw away the flashlight. The moment the flashlight landed, the light shone upwards. He had already had an extra gun in his hand, and flashed through Ren Yi's sight.

Gong Yingxian paused for a moment, and in less than a second, he ran towards the direction completely opposite to the stairs.

After Ren Yi realized what he was going to do, he shouted: "No!"

Gong Yingxian jumped out of the second floor window.

Ren Yi got up from the ground, endured the pain in his ankle, and ran downstairs.

Gong Yingxian ran out more than a hundred meters after a small man, and then pressed the man to the ground. The man shouted, "Let me go."

Ren Yi ran over and shouted, "Do you know how dangerous it is to jump into the window? Do you think you are making a movie?"

Gong Yingxian was unheard of it, so he took out the car key from his pocket and threw it to Ren Yi: "There are handcuffs in the passenger drawer."

Ren Yi glared at Gong Yingxian angrily.

Gong Yingxian grabbed the man's wrists with one hand and pressed his back with his knees: "Go."

Ren Yi turned around and went to Gong Yingxian's car, took handcuffs and threw them to him, and he neatly copied the man to the railing.

"Why do you catch me? Let me go!" the man shouted in horror.

Ren Yi squatted down and observed it. He was a young man in his twenties. He was thin and short, pale and looked malnourished.

Gong Yingxian said in a cold voice: "Who are you? Why are you here in the middle of the night?"

"I, I'm curious, can't I come and see it? Why do you catch me? What's the law I've violated!"

Ren Yi glanced at the backpack behind him and pulled it over.

"What are you doing? Don't touch my things! I, I have the right to privacy!"

Ren Yi took out the laptop, gimbal camera, a helmet with night vision light, and some miscellaneous things from it. He turned on the camera and there were many photos and videos from the fourth angle. His chest swelled, and he grabbed the back of the man's neck and said viciously: "Did you set the fire? Ah? Do you know how many people died? Beast!"

"No, I didn't! I didn't set fire!"

Gong Yingxian called and called the police officer to come over.

Ren Yi glanced at Gong Yingxian and saw that his suit was completely ruined. He was not much better. He was like taking a bath in a pile of coal ash, which was so dirty. He was a normal person, and he couldn't stand such dirty appearance. Gong Yingxian...

Gong Yingxian's limbs are stiff, his face is gloomy, and he looks like he doesn't know how to deal with it. For a patient with a cleansing obsessive body, it will definitely be very uncomfortable to do this.

Suddenly, Ren Yi found blood on the ground. He was shocked and circled around Gong Yingxian.

"What are you doing..."

Ren Yi grabbed Gong Yingxian's arm, looked at the long blood mark on his forearm, and took a breath.

Gong Yingxian pulled her hand back: "Don't touch me casually."

Ren Yi was too lazy to argue with him at this time: "Go to the hospital."

"No, I will handle it myself."

"Your injury at least needs to be stitched."

"I said, I will handle it myself."

"What the hell do you do? Hum?" Ren Yi started to anger, "Are you crazy? Jumping down from the second floor? A few days ago, when the fire was put out, a soldier jumped down at the same window and broke his leg. He had no choice but to force him."

"It's only more than three meters."
