An Yizhi and Tu Hongyu left the recreation room, and he planned to use the key he found from Eugene to check the safe in Eugene's room. Pen "Fun" Pavilion www.biquge.info

The old housekeeper originally planned to follow, but An Yi pointed out that it was too dangerous to use outside, and the possibility of an external criminal committing the crime could not be ruled out, so he persuaded him to go back.

To be honest, although the housekeeper has been very cooperative, An Yizhi has a feeling that he is being watched, not to mention, what they are going to do next is not very legal.

"This helmet seems to be equipment, hold"

"Oh, elite, yes, you can sell it for two bucks"

The two began to loot......

After finding two items in the study, An Yizhi had some realization, since the precious ancient book might be a magic book, then there may be other equipment hidden in this mansion.

As expected, when they inspected the armor in the hallway, they discovered that the helmet on it was actually a piece of equipment.

After some scourging, they found a good-grade longsword and an elite-grade helmet.

As for the attributes, there is no need to care, anyway, if you throw it to Tu Hongyu, the latter is also to sell or exchange it for what you need, so I won't say much.

Then the two went to the study to search it thoroughly, and this time they found a folded parchment paper in the mezzanine of the book's 'Classical Knight Swordsmanship Tactics' on the bookshelf, and the system identification result was an E-level melee skill, which was still given to Tu Hongyu.

An Yizhi had already taken the benefits, so what he found later was given to Tu Hongyu.

Now that the benefits have been taken, it's time to get down to business.

The two go to Eugene's bedroom and use the key to open the door to the safe.

Fortunately, this is a very old-fashioned safe, and there is no password or anything, otherwise An Yizhi can catch blind, and he will not have the skill of using a stethoscope to identify the password of the safe.

"Or ...... Key? ”

The safe contains only one key, except for some ornament-quality gems and pounds.

The key was large, resembling a small baton, with a hexagonal tip and many esoteric patterns and a devouring snake perched on it.

"This is a sign of alchemy, and it seems that Eugene's identity is not as simple as the boss of a pharmaceutical company"

"Something to do with the alchemy of ancient Europe? Anyway, wasn't that thing once regarded as an evil law and was wiped out by the church? ”

"There are always those who try to master alchemy and expect to get rich overnight, and most of them have been deceived by people using brass as gold"

It is a very simple chemical experiment, I believe that many people have been taught how to make fool's gold when they were in school, and that thing only looks like gold, which is the only way for many alchemists in ancient times to fool the authorities into hiring themselves.

But then again, the so-called alchemists are more likely to be a group of early chemists in reality, and whether these people are liars or not is not to be said, at least they have contributed a lot to the development of early human chemistry.

But combined with the 'zombies' that appear in this copy, the alchemy represented by this keylock is really not necessarily the 'chemistry' in reality, but may be a real guy.

"Let's not talk about whether it's real alchemy, how should this thing be used? You can't go back to the old house, can you? ”

It can be determined that there are some monsters like zombies roaming around the old mansion now, and they are not afraid of the infinite power of firearms, and they will be torn into strips of meat if they rush back.

"There's a place I haven't seen yet, come with me"

"Where?"

"Music Appreciation Room"

–‐‐——–‐‐——

The system doesn't schedule tasks that can't be done, and certainly doesn't schedule tasks that don't meet the difficulty.

The zombie monsters in the old mansion are certainly not something that only two players with pistols can deal with, and it is unlikely that this key will be used there.

So the goal was clear, they had explored almost all the rooms, except for the music appreciation room.

The two first went back to the recreation room to find the old butler and get the key.

After this period of time and the alcohol calmed down, Mrs. Green and the frightened manservant were in a much more stable mood, and Hamill and Charles were playing billiards on their own, and the other was throwing darts every now and then, and it seemed that there was nothing unusual in the time that Ann was away.

Get the key to open the door to the music room, which is much thicker than the other rooms.

An Yiyi touched the wall, and the place where he started was a little soft, which was a specially built sound-absorbing material.

"Why do I feel like this room is a little wrong?"

Tu Hongyu is a welder, but he also does chores related to interior decoration, and he also has a plumber's certificate, so as soon as he enters the door, he finds that this room is not quite right.

"What's wrong?"

"It's hard to say, but it feels like it's a little smaller, and this room should be bigger from the outside."

"Could it be that the sound-absorbing materials are arranged?"

"It doesn't take at least a meter to set up that thing."

"Yes, too"

Sound-absorbing materials are materials that are mainly used to absorb vibrations, and although those things are more space-consuming than ordinary wallpaper and other decorations, there is no need to think about the space of more than one meter as Tu Hongyu said.

In short, there is a dark passage in this house.

Due to the limitations of the era and architectural design concept, the impossible construction of dark passages in this era is too seamless, and it is normal to be found by Tu Hongyu, who is better at this aspect.

The two of them immediately began to search the room, and the shelves with a large number of records were the focus of their search, but those records were almost like books in the study, there were so many that they could not be searched for a while.

There are about three hours left in the countdown of the system, which is definitely not enough time to search all of them, and there must be clues that they haven't noticed.

If I were Eugene, how would I open the entrance to the secret passage?

It's possible under the floor, on the edge of the wall, or even behind the record stand.

Wait, the housekeeper said there was a fire here......

Like this kind of hidden door hidden in the room on the second floor instead of the first floor, obviously it will not be dug up by itself after the house is built, it must have been arranged at the time of design, so assuming that the secret passage already existed before the fire, then this secret passage and the method of opening the secret passage must not be afraid of fire, otherwise the secret passage will collapse or damage Eugene There is no need to cherish this key.

So, is there anything that isn't afraid of fire?

Ann glanced around, finally fixing his gaze on an ornament on the wall of the room.

It was a metal statue that looked like a screw or something attached to the wall.

Ann took a closer look at it and found that the bottom of the statue was unevenly painted, indicating that the statue had been repainted, but because it remained on the wall and could not be removed, the paint brush did not reach the bottom corners.

Got it!

Ann reached out with one finger, only to hear the sound of huge gears and mechanisms running from behind the wall, and the wall behind the record stand cracked a window.

It was a metal door with a six-pointed star painted on it and a snake devouring its own tail, with a hexagonal notch at the center of the circle, exactly the size of a key.

"Are you ready?"

Tu Hongyu nodded, holding a pistol in one hand, turning on the flashlight with the other, An inserted the key with one finger and unscrewed it.

The key sank into the door, and a strong force was heard that the key was swallowed by the metal door, and then the door slowly opened.

Tu Hongyu took the lead in the front, the attribute values of the two were the initial values, Tu Hongyu's physique was higher than An Yizhi's, plus he was more accustomed to hand-to-hand combat, so he walked in the front.

This is a staircase leading to the bottom, and when An Yizhi and Tu Hongyu step into it, a string of light bulbs light up on both sides of the passage leading to the bottom.

Tu Hongyu whistled and said:

"I don't need a flashlight now."

"Don't turn it off either, turn it on first"

This is so that they don't have to scramble in case the lights go out suddenly.

The two of them walked down the stairs, about twenty meters, and by this time they should have gone deep into the ground, and they saw a metal door blocking the way.

The door was not locked, and there were no traps after being tempted, but a passage engraved on the door attracted the attention of Ann Yizhi.

'One is all, all is one'

I believe that people who read this passage and have some knowledge of anime will think of the famous 'Fullmetal Alchemist' of the island country, but Yasuchiji didn't think so, he thought of another existence that was even more terrifying and incomprehensible.

- Yog. Sotos.

Damn, this can't be another copy of that kind of background, right?

Thinking in his heart, Tu Hongyu opened the door at this time, and what appeared in front of the player was a simple room, a bit like a laboratory for chemists to do experiments, with various beakers, test tubes, stills and other experimental equipment everywhere, and many solutions of different colors were placed on the shelves not far from the experimental table.

On the other side of the table, there was a huge cell that sealed off half of the room, but on the other side of the cell could be seen a gap that had been opened, and I didn't know where it led.

"This should be an experiment log, come and see, I'm on alert"

Tu Hongyu picked up a booklet on the experimental table and handed it to An Yizhi, who opened it without hesitation.

The booklet seems to be very old, not like it was written by a generation, with the first dozen pages of ancient parchment and the later modern industrial paper.

The system translation appeared in real time, and An Yizhi turned the first page, which read:

"Immortality"
