"I wrote all the situations in the Baosheng Chemical Factory explosion and the Gong family fire that year in the police report. My current memory cannot be more detailed than the police report at that time." Ren Xiangrong gave Ren Yi a vaccination, "I don't know how much I can help you."

"I understand that I have read the police report. I will ask some of the reports that are not included in the report. For example, is it possible that this explosion was man-made?" Ren Yi asked.

Ren Xiangrong shook his head: "The cause of the accident was the explosion of ethylene acetate. The explosion burning substances ignited other chemicals and caused a chain explosion. The reason for the explosion of ethylene acetate was investigated. When the workers transferred the chemicals to the reactor, static electricity was generated due to friction with the plastic pipe wall. The electric sparks generated by the static electricity ignited the volatile gas of the chemicals. But this was judged based on various physical evidence left afterwards. In fact, the entire workshop was blown up at that time, and twelve workers and technicians died on the spot. What happened before the explosion..." He pointed to the top of his head, "Only God knows."

"This judgment is relatively reasonable." Ren Yi said, "The security measures and awareness in that era were still relatively backward, and there was also a lack of modern various prevention and monitoring technologies."

Ren Xiangrong sighed: "These safety regulations, behind each word is a lesson summarized by blood and tears." He thought for a while, "Is there any problem with the investigation results of the explosion?"

"No, there is currently no evidence to suspect that it was made intentionally."

Ren Xiangrong breathed a sigh of relief: "I don't think it's possible, but even if it was not intentional, someone must be responsible for a production accident."

There was a bit of heaviness on the page.

In a production accident, from before the birth of the chemical to after the accident, every material that everyone touched and everything that happened during the period might be the wings of the butterfly, which eventually caused a terrifying storm.

Take the case of Baosheng Chemical Factory as an example. Every detail is crucial to the production environment and purity of chemical raw materials, whether the storage and transportation conditions are qualified, whether the packaging and use methods are compliant, whether the operator's training and management are in place, whether the accident plan and organizational rescue capabilities are in place, and every detail is crucial to production safety. Therefore, in such cases where even the cause of the accident is difficult to obtain evidence and investigate, the management and the producer will naturally bear the greatest responsibility.

In this accident, the investigation team believed that the plastic pipe material of the chemicals directed to the reactor did not meet the standards, and the aging of the grounding wire of the storage barrel, which together caused excessive resistance and accumulation of static electricity, which was the main cause of the explosion. Secondly, the stacking distance, quantity, temperature control, ventilation of other chemicals in the warehouse were unqualified. After one explosion, the chemical plant failed to control the fire in time. The two together caused a secondary explosion, which expanded the accident damage, and eventually caused 137 deaths and 269 injuries. The economic losses of 720 million yuan caused a large-scale production accident across the country. In addition, the losses caused by the secondary disasters caused by chemical leakage are even more immeasurable.

At that time, the procurement, engineer, workshop director, security captain, factory director and others of Baosheng Chemical Factory were all detained, and the management of Baosheng Group was also forced to investigate.

In the end, all major responsibilities such as purchasing unqualified materials, using aging equipment, and dereliction of duty in management fell on Gong Mingyu, the chairman of the group who "death of suicide in fear of crime".

After experiencing asset restructuring, Baosheng Group has changed its name and surname. After several years of restoration, it has regained a place in the chemical industry.

Recalling the past, Ren Xiangrong was still very sad. When talking about the dangers during the rescue and the lost comrades, he couldn't help but have red eyes.

Ren Yi felt guilty and felt that he was really unfilial to ask his father to recall such a cruel past. He said, "Dad, I roughly understand the case of the chemical factory. I will go find information by myself later. Tell me about the fire in the Gong family."

Ren Xiangrong wiped his eyes: "That, it's so miserable, so miserable."

Ren Yi thought of everything Gong Yingxian encountered, and it was difficult to suppress his heartache. No language or picture could describe the hell that Gong Yingxian experienced. No one, even if he had more empathy or empathy, could not understand Gong Yingxian's pain. This made him feel powerless anger.

Ren Xiangrong said slowly: "It's been so many years, and I can't remember many details. What impressed me the most was that after entering the fire, the family of four hugged in a group and hugged under the windowsill in the bathroom."

Let the hands tremble slightly.

"Parents... used their bodies to block the fire for their children, and the girl blocked her youngest brother behind her. The family of three was burned unrecognizable. Only the little boy was almost unharmed." Ren Xiangrong's voice was choked, "The girl was not dead at that time. I heard that she had suffered for a few days in the hospital..."

Ren Yi lowered his head and his breathing became extremely difficult.

"When I carried the child out, he was frightened silly, he couldn't scream or cry..." Ren Xiangrong turned his face over.

Ren Yi took a deep breath and said in a gentle tone: "Dad, with your experience and intuition of firefighting all your life, do you think it was the fire set by the male owner?"

Ren Xiangrong was silent for a moment: "Until the investigation results came out, I never thought it would be suicide. They showed a strong desire to survive. All the roads leading to the exit were blocked by fire. The family hid in the bathroom, but there was an anti-theft net on the bathroom window, so they could not open it."

"It doesn't seem like suicide at all." Ren Yi repeated.

"It's not like." Ren Xiangrong said, "However, I regretted it after committing suicide. Besides, the fire investigation was completely the work of the police in that era. Our work ended after putting out the fire and submitting the police report. I learned the results of the investigation later. Although I found it incredible, I didn't think much about it. After all, Gong Mingyu had just experienced such a big change and had a motive for suicide."

"Can you remember more details?"

"At that time, I thought it was important, and it must have been written in the police report." Ren Xiangrong Si asked, "I read the draft of my police report yesterday to help me recall it. The cause of the fire must be arson, which has a combustion aid, and deliberately blocked the escape route, but the doors and windows are intact, and there is no trace of forced entry by external forces."

"So what about the people wearing masks that Gong Yingxian said? Are there any traces of others in the house at that time?"

Ren Xiangrong frowned: "At least we didn't go in when we went in. It was burned into such a house and the living person could not stay, so that person must have left long ago."

"No sign at all?" Ren Yi said, "Dad, please recall carefully if there are any special details."

Ren Xiangrong thought for a long time: "Generally, people who want to commit suicide, especially those who take their whole family to commit suicide, will choose gentle and painless methods, such as burning charcoal and taking medicine. Gong Mingyu has been a rich young master since he was a child and has never suffered in his life. No matter how he thinks, he doesn't seem to choose such a tragic way of death, let alone bringing his wife and children. When something happened, the whole family was wearing pajamas, which seemed to wake up from their sleep. This is not in line with the characteristics of suicides, especially those who have lived abroad and paid great attention to dressing in those days. They were decent when they were alive, and how could they not be decent when they died?"

"You are right. Even ordinary people want to leave decently when committing suicide."

"We were on the police together at that time, and no one thought it was suicide. The scene was obviously arson. However, after the investigation results came out, it was said that Gong Mingyu was hit too much and had an abnormal mental state after the chemical plant accident, so everything seemed to be explained." Ren Xiangrong suddenly thought of something, "Wait... the fire point."

"What?"

"When I entered the fire, the living room was very hot, but I felt that the living room was not the fire point, it seemed that it was not the fire point, or there were other details at that time, so I could judge based on my experience that it was not the fire point, and the fire spread there along with the combustion aid. But this was just my first intuition judgment. As a firefighter, I judged that this was to first ensure the safety of myself and the soldiers. But later the investigation report showed that the fire point was the living room, and I didn't doubt it at the time, because the fire investigation was not my job, just like the police could not question how I put out the fire."

Ren Yi was shocked: "If there is a problem in judging the fire point, then the victim's survival route will be problematic." According to the structure of the house, evidence is retained on site, the victim's physical fitness and the location of the final discovery can restore the victim's survival route, and the fire point plays a key role in determining the survival route. Not only that, the fire point is crucial for the investigation of the entire cause of the accident. Therefore, the first thing to look for in any fire investigation is the fire point.

If the fire point is judged wrong first, then the route of survival reflected may be wrong. Assuming that the fire point is on Gong Mingyu's way back to the bedroom, then he will not be able to pass after setting the fire. How could he appear in the bathroom with his whole family? Such a logical loophole can fully prove that Gong Mingyu is not the firemaker. Although this is just a hypothesis, Ren Xiangrong, as the first rescuer, is often very reference-based based on experience and intuition.

Ren Yi said: "Dad, this is very valuable. Gong Yingxian is using modern technology to repair the on-site photos of that year. I decided to re-invest the fire."

Ren Xiangrong sighed lightly: "Son, if this case was really a murder, then there would be more people involved. Do you know what you are going to face? It's been eighteen years, and it will cost too much to overturn the case."

Ren Yi nodded confidently, "Dad, don't stop me."

"I won't stop you." Ren Xiangrong said calmly, "You have the same temper as me, and I know it's useless to stop you."

Ren Yi smiled freely and lightly: "Dad, the mission of the firefighter is to save people. Not letting go of an arsonist is equivalent to not giving up a victim."

"I've finished repairing the photos, let me show them, maybe I can remember more."

"Okay, I..." Ren Yi's phone suddenly rang, it was Gong Yingxian who called it, "Hey?"

"Ren Yi, are you in the squadron?" Gong Yingxian's voice was a little low.

"Here, what's wrong?"

"I'm in the squadron." Gong Yingxian paused and said softly, "I want to see you."
