When you open a completely unknown door, you may encounter many situations. For example, there may be an ambush behind the door, or there may be a trap waiting for a rash intruder behind the door.

However, nothing unexpected happened this time. Kaya and Kou opened the door and took a quick glance to confirm that no obvious threats were found. They motioned to Perrenli and Eve behind them to follow, and the four of them filed in quietly.

influx.

The first thing that catches the eye is a larger and thicker double door. The door is tightly closed, but there is no keyhole on the door. It should not be a lock structure.

Looking to the left and right, there is a very wide corridor, with a blue-light "torch" hung on the wall to provide dim light.

There is a large row of wooden doors arranged along the right side of the corridor, and unlike ordinary doors, they are arranged very closely and have a long opening above and below the door panel.

It feels like the upper opening is for easy observation of the inside, and the lower opening is for easy feeding of food inside.

This design was obviously abnormal, and everyone immediately realized that the narrow spaces behind the doors were probably used to hold victims who were abducted here.

In addition, against the wall on the other side, you can see the long tables that fill the entire corridor. There are many glass or brass utensils on the tables, such as beakers, test tubes, narrow-mouth bottles, and even

I came across something similar to an alcohol lamp, which felt like it was used for experiments.

After quickly observing the surroundings and confirming that there was no danger, Eve, who was walking at the back, gently closed the door, while Kaya at the front turned around and gave everyone a look, signaling to disperse and continue the investigation.

Kaya and Korra looked to see if there were anyone else in those narrow rooms, while Perrenli and Eve looked at the experimental equipment on the other side.

There is no "chemistry" as a subject in this world. The people who use these experimental equipment are most likely alchemists, and most mages can also study a little bit of alchemy, so this part is left to them to explore.

However, although it is said to be an experimental instrument, there are actually some other unfamiliar things, such as an unknown instrument that is made of brass and looks a bit like a ball, with some traces of burnt underneath.

Pei Renli kept a distance and observed these utensils carefully. Most of them had been roughly broken into pieces, and the fractures of the fragments were very new and not covered with any dust. Some small pieces of colorful liquid remained.

There are no obvious signs of drying in the bottle, indicating that it was done recently.

Different from Pei Renli's careful observation, Eve was relatively... resistant to these alchemy supplies?

All in all, he doesn't seem to want to get close, but that's understandable. It's very necessary to be cautious.

The first lesson taught in the Adventurer School is that it is best not to touch things you don't know directly, especially things related to magic.

Not to mention Eve, when Peri Renli was observing the table, he also found that there was a stench in the air that was completely different from the smell of sewers. It felt like something was rotten, and there was something mixed with the stench.

The pungent smell is so irritating to the eyes.

Pinch your nose, lower your head and look down at your feet. Under the dim blue light, you can see an oily liquid sprinkled on the ground. When the liquid gathers in certain low-lying areas, it looks like a light red paste.

This is kerosene, an extremely flammable liquid that can burn for a long time. It is usually used in city defense operations. It is strictly prohibited for individuals to produce and carry it. Only the army has stocks.

Judging from the amount of kerosene and the trajectory of the spill, it looked like someone was holding a bucket of kerosene and spreading it as evenly as possible while walking around.

I always feel that all signs indicate that this is the rhythm of destroying evidence...

These thoughts were running through his mind. Because Pei Renli had just lowered his head and looked at his feet, his gaze was lowered. When he looked up, he saw something like a book stuck in the gap of the table.

He took out his dagger, fiddled with it a few times with the tip of the sword, and pulled the thing out of the gap.

This is not a book, to be precise, it should be a manual, and it only has a few pages in total.

Moreover, it seemed to have been used for a long time, and the paper was obviously yellowish, and there was a large pool of orange stains of unknown origin on the cover.

After testing it to see if it was safe, Pei Renli picked it up and opened it to check.

Most of the first page, like the cover, was stained and it was impossible to see what was written, but the second half of the first page was still barely legible.

‘…Alchemical solvents are suitable for almost all potions. The finished product is exquisite royal blue with a slightly viscous texture, and can analyze the effective ingredients of herbs’

Could it be an alchemy notebook?

Pei Renli was immediately interested, and he immediately turned to the next page. This time, the text was not contaminated, and he could clearly see that the title of the second page read "Healing Potion."

And below you can see a lot of materials and the names of the required equipment neatly listed. If you continue reading, you will find detailed procedures on how to operate.

This is the magic potion recipe.

If you want to make a potion, a recipe is necessary. Otherwise, if you start from scratch, an alchemist will not be able to research several effective potions in his lifetime.

Continuing to scroll down, the formula is still the same, but it is not a healing potion, but such as invisibility potion, shielding potion, resistance-increasing potion, etc.

These formulas are widely circulated. If you are willing to look for them, you can buy them at a magic shop for money. They are not that rare, but spending money is already a big problem for Pei Renli now...

Of course, just having the formula is not enough. If he wants to try it, he needs to prepare a large amount of materials and equipment, which is another huge expense.

Therefore, Pei Renli didn't look too carefully, and quickly browsed through the names of each recipe as if on a whim.

When he turned to page 78, Pei Renli saw that the title this time said "Orange Paradise". Strangely, the main ingredients listed below also said "Orange Paradise".

He had some impression of this name. Yesterday he borrowed a book called "Encyclopedia of Dangerous Plants" from the school library. Because Volume 1 was borrowed, he could only start reading from Volume 2.

I remember that the first one in the catalog at the beginning was Orange Paradise, but because he was so sleepy, Pei Renli just flipped through the catalog and went to bed, so he didn't know what Orange Paradise was.

At this time, someone touched Pei Renli's arm. He turned around and saw that it was Eve.

She held a small thumb-sized glass bottle filled with some kind of light orange powder, put it into Pei Renli's hand, and said in his ear in a very low voice:

"This is orange heaven, an extremely dangerous plant pollen that is banned in most countries."

Damn it, this is really not all a human trafficking case!

After calming down, Pei Renli stuffed the small bottle into his pocket and continued to flip through the notes in his hand.

After Orange Heaven it no longer looks like a recipe, it looks like someone's diary.

October 30th.

'Some sneaky guys appeared outside my workshop. They didn't seem like good people. I don't know where they learned that I would mix Orange Heaven. I obviously never told anyone, no matter what they said.

None of them can admit it'

November 10

'Today I came to the temporary research laboratory they built for me. The environment is relatively poor and the equipment is not complete, but I have to say that the offer they gave me is really hard to refuse.'

From these two records, we can feel that the capitalist's urging method made the alchemist who left the record really fragrant.

November 15

'These guys not only asked me to help prepare Orange Heaven, but also asked me to help make a further orange elixir. I still don't understand how they found out that I can make it, but for the sake of gold coins, I can only say

no problem'

December 13

'I'm a little confused about the identity of this gang. Isn't it just a gang that wants to make money by selling Orange Paradise? They actually arrested a lot of people, and it doesn't look like they intend to sell it. In fact,

is very strange'

January 5

'When I was at work today, I happened to pass by a person. The strong necromantic power on his body made me shudder. I didn't expect these guys to have contact with the necromancer. Sure enough, I didn't delve into the purpose of their arrest.

Correct, in order not to be silenced, I may need to make some preparations'

February 22

'People are constantly being arrested, and some sacks are being transported away. I try not to show unnecessary curiosity, but today they asked me to test the effect of the orange elixir on the arrested people. Maybe they don't have much confidence in me.

Well, after all, orange elixir is not that easy to make, but of course I have no problem.'

March 30

'Today they informed me that the work here has been completed, and told me to destroy all traces and evacuate quickly. As for the experimental products, just pile them up casually. I heard that they will have someone responsible for the aftermath. From today on, I have not seen them, and they have not seen them.

They have never met me. I can see that their credibility is good. I have received all the money, and I also have a little understanding of their identity. If you want to kill people and silence them, the worst is to die together.'

The record ends here, and there is only a blank space behind it.

This diary probably accidentally fell into a gap in the table when packing things away. The original owner probably didn't think it was an important item, so he didn't look for it carefully.

Due to time constraints, Pei Renli could not read every page carefully. He skipped through it, but he could still understand the general process.

He raised his eyes and looked at Korra and Kaya. They had just checked the small rooms originally used to hold the victims, but they all shook their heads and said that they had not found anyone.

According to the diary, everyone had evacuated. It was not surprising that no victims were found, but the diary mentioned that someone was responsible for the aftermath.

This is the aftermath.

Just look at the kerosene on the ground.

In addition, since there is still someone guarding the door, it means that the person responsible for the aftermath is probably still here, otherwise when Pei Renli and the others find this place, they will only see a burning flame.

——Bang!

"Stop telling me these useless things! If it doesn't work, it won't work!"

Just when they thought of this, a sound like something hitting the ground and a roar that sounded like a man came from behind the double doors they saw as soon as they entered. Because there was a door across the door, the sound seemed very dull.
Chapter completed!
