Today's test was another major failure.

Following the faint sensation of that flesh and blood, You Yonghuai groped his way in little by little and soon arrived at the police station lobby.

A pretty young woman stood in front of the counter, angrily slamming her hand on a black-covered notebook, saying, "I'm going to complain about the store that sold this notebook!"

"Miss, this kind of thing isn't under our jurisdiction... How about I transfer it to the Market Supervision Bureau for you?" The police officer behind the counter glanced at the notebook and suggested.

His gaze fell on the notebook, and it seemed that the source of the flesh and blood that You Yonghuai sensed was that notebook.

"Excuse me, may I take a look at this notebook?" You Yonghuai stepped forward and interrupted their conversation.

"Who are you?" The woman looked You Yonghuai up and down, handing him the notebook as she asked the question.

The laptop feels very smooth to the touch and has a faint, pleasant fragrance that seems to have seeped into the cover, giving it a very good texture.

"Is there anything wrong with it?" Just looking at the cover, Yu Yonghuai couldn't see anything wrong with it.

"Open it and take a look," the woman said, also wanting to express her dissatisfaction with the notebook.

When I opened the notebook, the paper felt brittle, and the stitching in many places was loose, which was completely different from the exquisitely made cover.

"This notebook is of very poor quality; it's impossible to write on it. I originally wanted to go back to the store to complain, but they haven't been open lately, so I came to you instead."

"We'll handle this; we won't let the merchant infringe on your rights," You Yonghuai replied. "May I borrow this notebook temporarily?"

"Are you a policeman too?" The woman saw that You Yonghuai wasn't wearing a police uniform and looked young, so she assumed he was at the police station on business. "Take it if you want it. This piece of junk is useless anyway. I even spent forty yuan on it because it looked nice on the outside."

"Could you please tell me the store's location? I'll go there as soon as possible to handle it. Also, it would be best if you could leave your contact information as well."

After seeing the woman off, You Yonghuai took the notebook back to the storeroom and chanted the incantation in a low voice once more.

The notebook's cover then began to vibrate slightly, as if it would change once You Yonghuai finished reciting the incantation.

"...This thing is made of human skin?" You Yonghuai pinched the black cover of the notebook, somewhat incredulous.

He then found Ye Qingchen and Ling Xiuqi and explained the situation.

The former had a lot of people to interrogate and couldn't spare the time to help, while the latter cut off a small piece of skin and sent it for testing.

"It is indeed human skin, belonging to someone who went missing a few months ago... Looks like you've done a good job." Ling Xiuqi said after looking at the report. "We're not sure about the shop yet, you can go and check it out yourself first."

Ling Xiuqi still has many small wounds on his body. Although they don't have much of an impact, they attract too much attention on the street and are likely to draw unwanted stares.

Anyway, he's in good health, and it won't take him more than a few days to recover. He doesn't plan to go to crowded places in the next few days.

"I'll help you find out about that unlucky node. You should deal with the laptop issue first and then come back."

"Please contact us anytime if there are any special circumstances."

After hearing Su Rou's words, Ling Xiuqi thought of something a student at Wenjiang Middle School had said back then—

Wenjiang Middle School was built on a cemetery.

Ling Xiuqi later checked and found that this statement was true.

It wasn't a large-scale cemetery, but rather a few small graves that hadn't been visited for a long time.

Furthermore, the fact that both the laboratory and the Wujian School seemed to be tinkering with something at this school made Ling Xiuqi even more suspicious.

However, since it was just speculation, Ling Xiuqi didn't tell You Yonghuai for the time being.

Even if you guess right, nothing bad will happen, but if you guess wrong, it will be very embarrassing.

After giving You Yonghuai a few more instructions, Ling Xiuqi told You Yonghuai to handle the matter himself.

After all, everyone needs exercise.

After changing into a police uniform, You Yonghuai left the police station and headed to the address the woman had given him, carrying the notebook with him.

The shop wasn't far away, only about half an hour's walk. For You Yonghuai, who always gets stuck in traffic, walking was definitely faster than taking a car.

In fact, You Yonghuai didn't really want to hold this leather notebook in his hands, but it was not only evidence, but could also be used as material for some small flesh magic when necessary, which is why You Yonghuai carried it with him.

The shop the woman mentioned was called Mr. Leather Goods, located in a fairly large storefront on the street. The decor was quite elegant and had a certain charm.

By the time You Yonghuai arrived, it was already dark. The lights in the shop were off, which somewhat affected visibility, but the door was unlocked and could be pushed open to enter.

The doorbell rang automatically, but no one came to greet him. You Yonghuai looked around and called out, "Is anyone home? I'm here to check the business license."

The fairly spacious shop is filled with a wide variety of goods, from small notebooks to large leather jackets; this shop has almost everything that requires the use of leather.

You Yonghuai glanced at them casually, then tried touching them. He felt that the leathers had a very nice texture and a pleasant fragrance, and he could tell that the maker had put a lot of effort into them.

If only the raw material wasn't human skin...

After trying to whisper a few syllables, You Yonghuai realized that all the products in this shop were made from human skin.

Furthermore, they can all be used as materials for his flesh and blood magic.

"Coming, coming!" A clear voice came from behind the counter. A man lifted the curtain covering the passage and came out with a gentle smile on his face. "Sorry, I was making something and I'm a little late."

"Someone reported that your products are substandard and you're deceiving consumers," You Yonghuai said, glancing around the room and speaking in a serious tone. "Where's your business license? Why isn't it on display?"

"Sorry, I forgot about this." The man smiled apologetically, bent down and took a board from the cabinet, saying, "Look, this is my business license. I'll hang it up in a bit."

You Yonghuai took it and looked at it, his fingertips tracing the surface of the board, and his brows furrowed.

The business license is fake.

If it were a genuine forgery, You Yonghuai certainly wouldn't be able to tell the difference, but this board was made using illusion magic.

It just so happens that You Yonghuai possesses this ability and is quite sensitive to it.

A faint aura of spirituality emanated from him as he traced his fingernail across the magic circle on the board. After destroying the illusionary magic circle, You Yonghuai patted the board and said, "You think carving a few lines on wood counts as a business license?"

"Huh?" The man took the board in disbelief and quickly noticed the scratches on it.

A flicker of malice crossed his eyes, but he quickly concealed it, a smile playing on his lips, revealing no trace of guilt. "Perhaps I took the wrong one. The business license should be inside. Why don't you come in and take a look?"
