You said you would tell fortunes, so you can catch ghosts and exterminate zombies easily?

Su Chen glanced at the two of them.

Yu Shengjie and Xia Liwei subconsciously shrank their necks.

After all, he is a young man. Although Xia Liwei has good Taoist power, he has not been tempered, so he is still concerned about the big picture and tends to be stubborn.

Captain He must be having a headache dealing with these two.

His gaze fell on Gong Zi again, and he explained, "The body is of a male, 170cm tall, about 30 years old, with fractures in his hands and legs. He died of starvation, and his identity has not yet been determined."

Du Jingnian suddenly realized: "Brother Gong, that should be someone who came to Shanghai to work, right?"

Gong Zi nodded: "Nine out of ten, but what is his identity and whether it is related to this matter, we need to investigate carefully."

Yu Shengjie muttered, "A laborer could be starved to death. How pathetic! Even if he died and became a fierce ghost out of resentment, he probably wouldn't dare to hurt anyone, right?"

Gong Zi didn't say anything.

Xia Liwei quietly observed Su Chen, who was well-behaved and well-behaved.

Su Chen followed Gong Zi to the flower garden where the body was found.

"The body was hidden inside at that time."

"It must have been done by the homeless people in the building."

Xia Liwei was curious: "Why not just call the police? Someone's already dead."

Du Jingnian explained: "They are afraid of trouble."

"People living in abandoned buildings like this usually choose to do odd jobs or manual labor. If they are called to the police station to cooperate with the investigation, a whole day will be wasted."

"Besides, I'm still worried about being suspected of being the murderer and being unable to get out once I go in."

Xia Liwei frowned: "You're not wrongly accusing anyone, are you?"

Du Jingnian just smiled.

Seeing this, Gong Zi hurriedly led the way: "Oh, let's go inside the building and take a look."

"The leader of the textile machinery factory said that after the employees moved out, they arranged for people to clean the building, so every room was almost empty. But now, it's full of things the homeless brought back: bedding, washbasins, clothes, socks, and so on."

There was even feces in some rooms, which smelled terrible.

Yu Shengjie, Xia Liwei and others had been here together before, so they were familiar with the place.

However, after checking again, Xia Liwei took out the compass.

Yu Shengjie took out a yellow silk thread about one meter long from his pocket.

As soon as he got it in his hand, the thread automatically coiled around Yu Shengjie's fingers, one circle after another, like a ring.

Su Chen took a glance and thought it should be some kind of nematode that was very sensitive to Yin energy.

Gong Zi pushed open the doors one by one and let Su Chen and the others go in to check.

The homeless man's belongings were numerous and messy. After walking around, Su Chen nodded and said, "It's really quite strange. There is yin energy, but no wandering ghosts."

Then he reminded: "Check each room carefully."

Yu Shengjie and the others nodded repeatedly: "Okay."

With Su Chen around, even though they were looking through the homeless man's things one by one, they were still quite fast.

An hour passed.

Su Chen squinted his eyes as he looked at the toothbrush with only a little bristle left in his hand.

Yu Shengjie and the others looked at each other and didn't dare to speak.

This is the last room.

After careful investigation, it seems that I still found nothing.

Du Jingnian hesitated for a long time and asked in a low voice: "How about I go and ask that old man in detail?"

He was naturally talking about the ghost from the Republic of China.

Gong Zi was somewhat tempted.

His eyes fell on Su Chen, but he didn't dare to nod easily.

Su Chen walked to the window and looked down.

Scenes passed by my eyes, but I still had no clue what was going on.

Under the eyes of heaven, nothing can escape detection, so...

Su Chen asked Du Jingnian: "Were you here last night? Is there anything unusual in this building?"

Du Jingnian shook his head.

There is still a clue, what will it be?

Su Chen narrowed his eyes again, and the details of each room flashed before his eyes.

Suddenly he stopped and strode towards one of the rooms.

Although Du Jingnian and the others were puzzled, they still followed closely.

Su Chen tried all the suspicious places one by one.

Then it stopped in front of a door.

His eyes were fixed on a simple arithmetic problem carved on the wooden door.

“2+2=”

The wooden door was covered with dust, but after the arithmetic problem, although there was no word engraved on it, a "4" was revealed because it was too clean.

Gong Zi asked cautiously: "Master Su, is there any problem with this door?"

"Give it a try."

Gong Zi was just about to ask how to try it when Su Chen had already raised his hand and started gesturing with the number 4.

His fingers were clearly on the wooden door, but when he was halfway through, Su Chen felt a faint yin energy flowing through his fingertips.

The compass needle in Xia Liwei's hand began to spin rapidly.

The nematode on Yu Shengjie's finger slowly stretched out half of its body.

Gong Zi stepped forward cautiously and subconsciously protected Du Jingnian.

The wooden door in front of me suddenly looked like a mirror, or like the surface of shimmering water.

Amidst the ripples, they all heard a light yet serious voice.

“Mathematics is the foundation of all science…”

A classroom seemed to appear in front of me, full of people, young and old.

But soon, the classroom disappeared.

Along with the people inside.

Yu Shengjie wiped his eyes, and all that was left in front of him was the ordinary wooden door and the arithmetic problem on it.

"Master Su, there really is something wrong with this technique."

"I'll try too."

As Yu Shengjie was about to imitate Su Chen to describe the number 4, he was stopped by Su Chen.

"Come in the evening."

He intuitively felt that it was because it was daytime, so the classroom couldn't last long.

"Oh, okay." Yu Shengjie nodded quickly and retracted his hand.

Su Chen tried all the remaining suspicious places and confirmed that only the wooden door had a problem, then he looked at Gong Zi.

"This inscription was carved a long time ago. Let's check who carved it."

"it is good."

Du Jingnian hesitated: "Then Master, should we meet here tonight? Or should we go to the old street to find you?"

"Here it is."

Su Chen turned around and wanted to leave, but after hesitating for a while, he turned back and reminded: "You guys follow along and check together, pay attention to the details."

"Yes." Xia Liwei's tone was firm, which scared Yu Shengjie.

After Su Chen left the ghost path, Yu Shengjie grabbed Xia Liwei's neck and said, "Tell me, are you shouting so loudly to make yourself more prominent in front of Master Su?"

Xia Liwei waved his hands repeatedly, and then heard the former angrily:

"Why didn't you call me? Are we still good brothers?"

Xia Liwei: “…”

Back to the old street.

Little Liu'er sat on a small stool, holding her chin with her hand and frowning.

"What's wrong? Didn't you sell the bamboo rice?"

Xiao Liu'er shook her head. She looked at Su Chen several times before she took out a small wooden sword as thick as a finger.

"My aunt just gave it to me."

Su Chen glanced at it and said, "It's a consecrated magic weapon, given to you for personal use. What's wrong?"

"Master Su, if I start praying to the gods now, will my aunt be blessed?"

"Why do you ask so suddenly?"

Xiao Liu'er lowered her head: "I just had a premonition..."

Su Chen touched her head.

"Don't overthink it, kid. What you should be worrying about now is how to sell the remaining bamboo rice, and how to wash all these bamboo tubes."

Xiao Liuer forced a smile: "Okay~"

She looked at Su Chen twice more and said, "Master Su, will you come here to set up a stall tomorrow?"
