Yang Zhengning stood on Xiong Yingjun's side and had always placed high hopes on this "hero's child".

Moreover, Yang Zhengning knew that as long as this easy case was solved, Li Nan would have the most basic capital. At the very least, his position in the Fate Division would be secured, and he wouldn't have to suffer in the sun and wind at the Day Patrol Division anymore.

Because of this achievement, perhaps Li Nan can turn over a new leaf and regain the same vitality as his father!

Yang Zhengning made the right bet!

In the interrogation room, Li Nan wasn't particularly interested in the interrogation.

It was well past his get off work hours, and he had originally planned to have dinner with Qin Wen today.

Of course, Qin Wen never agreed.

However, the interrogation had barely begun when the confession of the person turning himself in struck a chord with Li Nan, changing his mind.

“My name is Liu Damao, I am 48 years old, and I am from Yinghuadu, Tanhua City. In 1992, I killed a man named Qin Jianguo!”

There are many people with the surname Qin, more than 100,000 in Tanhua City alone. However, there is probably only one person with the surname Qin, named Jianguo, who died in 4192!

This is the man Li Nan considers to be his future father-in-law!

Qin Jianguo died in an accidental fall at a sugar can factory in 4192!

During the ten years that Li Nan knew Qin Wen, he had overheard about this incident during their interactions. Taking advantage of his position, he had also seen the case of the fall that was classified as an accidental death in the archives department!

How could this be an accident?

It was only because of the characteristics of that era that it had to be classified in this way in the end!

Qin Wen once said, "I will not date, let alone get married and have children, until I find out the truth about my father's death!"

Now, the truth is right before their eyes, within easy reach. Looking at Liu Damao, who has confessed and is about to receive leniency, Li Nan smiled.

After listening to Liu Damao's confession, Yang Zhengning and Li Nan both understood that it wasn't that the patrol guards back then were incompetent, nor that they lacked ability.

The act of exchanging murders sounds familiar now and is not a sophisticated crime method. However, in 1992, it was indeed ingenious and a very creative crime method!

Liu Damao is a veteran who joined the army at the age of 18 and retired at the age of 20.

His family couldn't support him to go further, and Liu Damao himself didn't like the monotonous life in the army.

After returning from military service, Liu Damao idled away his days and quickly spent all of his meager demobilization allowance.

If it were just him indulging in food and drink, the resettlement allowance of over ten thousand yuan back then wouldn't have been spent so quickly.

The problem is that he has an unreliable father who, like him, spends his days drinking and doing nothing productive.

By chance, Liu Damao met Cao Zhixiong, the guy who was competing with his father-in-law Qin Jianguo for the team leader position.

The two met under unusual circumstances and quickly became inseparable brothers.

During a heart-to-heart talk after drinking, the two shared their troubles and unexpectedly sparked a unique connection.

Cao Zhixiong thought to himself, "If Qin Jianguo dies unexpectedly, then the captain's position will definitely be mine! Although the sugar factory is poorly managed, it has a lot of illicit income. The captain's position is a lucrative job!"

Liu Damao thought to himself, "Now that Huaren has just started offering accidental death insurance, if I pay a large premium for my father first, and then he dies in an accident, then I will not only get rid of him, but also make a fortune!"

Both harboring their own ulterior motives, they quickly reached an agreement to swap murders in order to create alibis.

Not long after, Liu Damao's father accidentally drowned after drinking. At the time, Liu Damao was at a fruit market in Yinghua City and bravely intervened!

Later, one winter night, Qin Jianguo, the foreman of the sugar factory, accidentally fell into a sugar jar after drinking and tragically died. At the time, Cao Zhixiong was eating and drinking with his fellow villagers at a restaurant, and even vomited all over the place.

What did you do back then?

“Cao Zhixiong gave me a spare key to the factory. I ambushed him inside beforehand. When Qin Jianguo came in, I hit him a few times from behind. Qin Jianguo was still conscious at the time. I took out a bottle of liquor from my bag, poured a few mouthfuls of liquor into him, and then threw it into the sugar jar!”

Liu Damao is over 1.9 meters tall and is now in his forties. He still looks quite strong. More than 20 years ago, when Liu Damao had just returned from military service, it was just a piece of cake for him to do these things!

"Then why did you cause a traffic accident before turning yourself in? Isn't that just adding to your criminal liability for no reason?" Yang Zhengning asked.

Liu Damao laughed, "Didn't you all notice that the person crammed flat in the car was Cao Zhixiong?"

It turns out that what Liu Damao had just told was only the first half of the story.

There's a second half to the story!
