South city.

At the end of Changhong Road, there is the No. 13 bus stop.

The master and his apprentice, one holding a stick and the other holding a hook, were waiting for the arrival of the last bus.

Bus No. 13 is the only bus in South City that operates until midnight.

Of course, twelve o'clock is the last bus.

Because of the factory relocation and renovation of several industrial parks, Shisan Road had to work overtime until the early morning.

Li Shaohui looked towards the approaching bus and asked anxiously, "Master, haven't we missed the last bus?"

"It shouldn't be. The train leaves at 12 o'clock. This is our third stop. It should be here soon." Liu Jun shook his head.

"Yes." Li Shaohui nodded with great trust, and suddenly asked, "Master, if there is really a problem with the last bus on Route 13, then who is calling us, is it a human or a ghost?"

"Nonsense, it must be a human!" Liu Jun rolled his eyes at his apprentice and said without thinking, "Can a ghost make a phone call?"

"Yeah." Li Shaohui nodded and murmured, "But it's hard to say."

"call……"

As soon as he finished speaking, a cold wind suddenly blew, making the two of them shiver and subconsciously tighten their weapons in their hands.

The originally quiet and deserted station seemed a little eerie due to Li Shaohui's whispering and the cold wind.

"Gulp~"

Liu Jun couldn't help swallowing his saliva and glared at him, "Don't talk nonsense."

"good."

Feeling the abnormal atmosphere, Li Shaohui quickly shut his mouth.

“…”

The two were silent for a moment, listening to the whistling breeze around them, feeling that the situation was becoming increasingly eerie.

The master and the disciple looked at each other subconsciously.

Liu Jun said, "Xiaohui...why don't you say something?"

"Master...I thought so too."

Li Shaohui nodded and said, "The last bus on Route 13 goes to the old chemical plant. I heard there's a mass grave near the chemical plant?"

"Master, you are an old policeman with a lot of experience. Have you heard of this?"

“Tsk…”

Liu Jun frowned slightly, and suddenly a memory came to his mind.

After thinking for a moment, Liu Jun slowly said:

"This story all started with a family massacre ten years ago, the '412 Chemical Plant Massacre'."

"I wasn't even a team leader at the time. The first major case I was involved in was the '412 Family Massacre'."

“The chemical plant was relocated for this very reason.”

"The case is too complicated. I'll take you to look at the files tomorrow. I'll tell you the approximate results first."

"On that night of that year, a small explosion occurred at the chemical plant. A man named Da Zhuang was on duty when he was accidentally hit by the explosion and died on the spot."

"According to the regulations at the time, if a murder occurred, the chemical plant would be subject to severe punishment and would also have to make irregular rectifications. It just so happened that the authorities were conducting a strict inspection of factory safety issues at that time."

"So, the boss of the chemical plant wanted to suppress this matter."

"He first paid a worker who was on duty with Da Zhuang at the time, and later contacted Da Zhuang's family, also wanting to use money to settle the matter. In short, he wanted to buy his life with money."

"In theory, there was an accident at the factory and people have died. For Dazhuang's family, it should be good to get a large amount of compensation. After all, Dazhuang's family depends on him for support. If they insist on suing, they may not get half of the compensation in the end."

"In fact, at the beginning, Dazhuang's family also accepted this plan."

"But the problem is that the factory owner is unwilling to hand over Da Zhuang's body to them, because through Da Zhuang's body, they can find traces of the factory explosion."

"Da Zhuang's mother believed that fallen leaves must return to their roots, and she insisted on bringing the body back to her hometown."

“That’s where the conflict broke out.”

"Finally, during the scuffle, the factory owner accidentally pushed Da Zhuang's mother down the stairs, and she fell on her head and died despite rescue efforts..."

“…”

"The next day... I didn't expect..."

"That's how it was... In the end, things got out of hand."

"In the end, none of Dazhuang's family members survived, and their bodies were hidden in an open space nearby."

"I don't know where the news got out, so some people started calling that piece of land a mass grave, but in fact it was just Da Zhuang's family."

"We also got the clues from nearby villagers by accident two years after the factory moved..."

After recalling everything in one breath, both Master Liu Jun and his apprentice looked extremely solemn.

"Master... this factory owner is so abominable. He killed an entire family. Sigh..."

Li Shaohui sighed and said with emotion: "Da Zhuang's family is really miserable. Was the factory owner sentenced to death in the end?"

"No, the court hasn't even opened yet." Liu Jun shook his head.

"No?" Li Shaohui looked surprised and asked puzzledly:

"Why? He did such a heartless thing, and the case has been investigated, why?"

Liu Jun was silent for a moment, then said in a serious tone, "Because this case was not investigated while the factory owner was alive."

"What do you mean?" Li Shaohui was even more confused.

"The owner of the chemical plant jumped off the building on the seventh day after the incident. Otherwise, if he was alive, the news would not have leaked so quickly," Liu Jun explained.

“I see…”

Li Shaohui nodded.

Just as the master and his apprentice were thinking about the case, Li Shaohui suddenly said:

"The seventh day... isn't that the first seven days? Could it be that Da Zhuang has transformed into a fierce ghost and has come back to kill us?"

"Go, what are you talking about!" Liu Jun glared at him fiercely and said, "But according to the current situation, it is not impossible."

"The factory owner committed suicide, which means that this matter... may have some hidden story behind it." Li Shaohui continued.

"Maybe the people are asking for help, and it's Da Zhuang and the others who are causing trouble. The injustice has not been resolved, and the ghosts are still lingering."

"This... is hard to say..."

"Buzz~"

Just as the master and the disciple were talking, a bus slowly drove into the station and stopped in front of them.

The master and disciple subconsciously looked up.

It’s route 13.

The last bus of Route 13 is here.

“Crunch~”

The car door slowly opened, and the master and disciple took a peek inside. There were quite a few people there.

"Master... everyone says there's something wrong with this train, why are there still so many people riding it..."
