"Trapezoid...!!"

The girl was not stupid, she heard this explanation, and then observed the layout of the room, and suddenly realized.

The vision is deceived!

The room is a single cement color, and in this tone, the long and short lines are the most easily misjudged by the naked eye.

And most importantly, it's room 2013!

Under normal circumstances, 2012 next door is the cabin where the [Fallen Witch] is staying, and several rooms near it are mentally tainted.

No one is going to wander around here.

Even if someone passes by, the mental power will be disturbed, and those details will be overlooked.

Visual deception + mental interference, which also leads to the small difference in the distance of the iron gate will be ignored.

The distance between the doors is poor... This is a new discovery from the intelligence merchant whose most detailed information has never been recorded.

What a clever design!

The mechanical arm girl figured everything out, and then looked at the man who was so weak that she thought she could kill with a single blow, her face was full of incredulity: such interference, this guy actually noticed an abnormality?

This is no longer a matter of careful explanation.

“...”

After Ji Xun finished speaking, his expression was not different, and he didn't think it was a big deal.

In fact, he had discovered this problem a long time ago, but he didn't want to do much trouble.

And at that time, I didn't trust this temporary teammate enough, and I wanted to go out until the third day, so I didn't talk much.

But now it's different.

.......

In fact, in addition to what he said, there are many details that Ji Xun did not explain.

The structure of this bunker is very simple, with a hundred rooms on each floor, and only one rusted elevator on the upper and lower floors.

This design is problematic in itself.

First of all, the purpose of this bunker is in the name, [407 Anomalous Biological Containment] is clearly a bunker for research or something.

But where the lab is only about monsters?

The normal structure of the research could easily have been analysed to the location of the other rooms, which is why such a misleading parallel structure was created.

Follow this line of thought and check the room structure one by one, and you can also find problems.

Of course, the premise is that it can not be disturbed by the abnormal spiritual field on the second floor.

Ji Xun himself has a keen observation of the environment that is different from ordinary people, and he found the problem first after taking a few steps.

Then the whole space design problem is reversed.

Now that it is determined that this is a copy of "customs clearance and reward", the most interesting part of discovering the secret door for Ji Xun is not decryption.

But... Backward Engineered Level: What was the motivation for designing this level?

......

The mechanical arm girl has completely let go of her contempt for her temporary teammate.

didn't wait for anyone, she walked directly to the wall drawn by Ji Xun.

The door frame is also marked with a "✘" symbol in great detail.

The girl didn't delay, she raised the mechanical arm that had been stored and aimed at the marker, and didn't forget to remind: "You stand back." ”

Ji Xun naturally hid behind the girl.

Then there was a "bang", and the air wave almost overturned the person.

The two of them also heard the sound of bricks breaking in the wall.

"It's really broken!"

The girl with the mechanical arm looked at the big hole that shot out in front of her, her eyes full of disbelief.

Although she had been informed of the reasoning process just now, she still felt like a dream when she actually found a new direction to clear the level.

This also means that the way to clear this [407 Anomalous Biological Shelter] may really be as the man said, they have found a new way to clear the customs!

Ji Xun looked at the hole without any joy, because he had already made up his mind.

He looked at the swarthy entrance of the cave with a thoughtful expression.

It's easy to break the wall, which doesn't mean that the hidden story triggered is not difficult.

On the contrary, he felt that the designer was very confident in his follow-up design, so he did not make more articles on the wall.

Before they had time to think about it, the smoke and dust from the broken walls had not yet cleared, and the two of them saw a new revelation at the same time: "Trigger the hidden plot, increase the exploration by +5%, and get an additional reward for settlement"

The mechanical arm girl cautiously looked at the hole in front of her, like some kind of laboratory area, the green glimmer was eerie and terrifying, constantly giving people a psychological hint of a monster ambush.

Ji Xun seemed to be completely indifferent, and beckoned: "Let's go, let's go in and have a look." ”

“...”

The girl with the mechanical arm glanced at him, but still stood in front of Ji Xun, and took the lead in walking in.

She is well aware of her place in the collaboration.

I used to be in charge, but now it's this guy.

.......

It was a very messy lab, littered with signs of battle, with dried blood on the floor, several shriveled bones in white coats, and scratches from unidentified creatures on metal instruments.

A messy pharmacy table full of scattered beaker reagent bottles, a dissecting operating table, monster specimens soaked in yellow-green liquid, strange tools...

All kinds of instruments have a strong steampunk black technology style, and a strong sense of magic and mystery comes to the face.

It's like an alchemy lab, and it's like a biology lab.

The mechanical arm girl cautiously walked ahead, glanced around, and said, "This should be the research room of Bunker 407." ”

Sure enough, the institute can't just be a place to bet monsters.

Ji Xun looked around and nodded: "Hmm." Let's go for some useful clues. ”

“...”

The mechanical arm girl glanced at him, and she didn't know why this guy's tone was very determined, as if she would definitely find something.

There are also gas lamps in the lab, and the atmosphere is eerie, but the visibility is not bad.

The laboratory was huge, and there was a sound of rustling in the darkness from time to time, and I didn't know what kind of monster it was.

Ji Xun glanced at the layout of the laboratory and walked straight towards the row of rooms on his left.

The girl with the mechanical arm didn't speak, and followed beside her.

Ji Xun walked all the way over, and the single rooms were also all kinds of functional laboratories, some of which he went in to take a look, and some of which he just looked at at the door and passed by directly.

"What are you looking for?"

"I don't know yet."

“...”

The mechanical arm girl suddenly felt a little inexplicable, this guy didn't go to find the exit, here to find a clue that she didn't know what it was?

But soon, Ji Xun stopped in front of a room and said in a deep voice: "It should be here." ”

The girl with the mechanical arm saw that this room was larger than the previous ones, and it seemed to be the management's office.

Before she could figure out why she stopped here, Ji Xun had already walked in, and then rummaged through the cabinets for a while, and soon found a safe in the corner.

Safe?

At first glance, it is a very important plot item.

Before the mechanical arm girl could marvel at why this guy was sure that there was something here, she watched Ji Xun take out some crooked pieces of iron, put her ears on the safe, and began to tinker with the lock.

This is the "master key".

During the day, Ji Xun made it without incident.

It was originally designed to cope with the iron door locks in the cabin.

Although there are extraordinary powers and magic cards in this world, locks are still mechanical locks, and no matter how complex they are, there is a way to open them.

Fortunately, this safe is not too complicated in Ji Xun's opinion.

“...”

The girl with the mechanical arm watched quietly from the side and did not disturb.

This guy's calmness gives people a very reliable feeling.

She wasn't in a hurry to find an exit.

The laboratory was quiet, with only "crunch", "crunch"... The grinding sound of the gears turning.

Suddenly, there was a metallic crunch sound.

Ji Xun smiled slightly and said softly, "It's open." ”

So fast?

The girl with the mechanical arm was also a little surprised.

Looking at his professional safe unlocking skills, and thinking of his previous demeanor in analyzing the wall problem, she couldn't help but ask curiously, "What kind of profession are you?" ”

"Occupation?"

Ji Xun pondered for a moment and responded: "I'm an actor." ”

Mechanical Arm Girl: "I'm asking about the career sequence. A thief? ”

I thought it was a spiritual transcendent, but it didn't seem to be.

“...”

Ji Xun couldn't answer.

He was an actor before he crossed over.

A clown actor who was adopted by a circus since childhood.

That inexplicably high mental power is related to this profession.

The clown has played too many roles, and one day he is acting, only to find out that he doesn't know which one is his true self.

Or maybe each one is a part of itself.

Ji Xun clearly felt that there were many selves in his head, playing different roles.

It's like he's been calm all along, and he's not without "fear". Rather, it is "sanity", "curiosity", "excitement", "curiosity", "twisted madness"... And so on other characters suppressed.

This kind of overload of mental activity allows him to learn things quickly, and at the same time have a careful and active mind.

It also allowed him to learn to master almost all the difficult juggling in the circus.

What tightrope walking, throwing knives, underwater extreme escapes, firearms, flying cards...

"Lockpicking" is a mandatory skill for underwater escape.

But that mental power also troubled him.

He can't feel the mood swings of a normal person, such as happiness.

This made him more and more fond of thrill-seeking for a while before the crossing.

Use that sensory stimulation to find some ways to vent your mental distress.

......

The thoughts in my head flew for a moment, and then turned back.

Ji Xun opened the safe and took out a stack of materials.

The contents were messy, as if someone had rummaged through them, and a part of it was missing.

The girl with the mechanical arm also leaned over, and at this look, both of them were attracted to it.

Enlightenment transformed a cuneiform-like ancient script into a readable form.

"On May 3, 1141 in the Imperial Calendar, the 'S-Class Cataclysmic Source' was unsealed and research began."

"Experiment Chamber-1001, #1144, Subject Awakening's supernatural abilities have been changed, showing a high tolerance to the dark element... Injected with a tenfold dose of 'Heim Type VII. Ash Reagent', the body's tolerance continued to increase, and five days later, an unknown direction distortion occurred... Conclusion: This source card has S+-rank Dark Elemental Affinity Growth."

"Experiment Chamber-1099, #815 Subject attempted to implant a contaminated limb [Giant Magic Muscle], the potion induced a surge in strength, and his physical attributes miraculously broke through the upper limit without changing jobs, but the subject lost his mind... On the 14th, the distortion was uncontrollable, and he died on the same day. Conclusion: The source of the catastrophe has the power system with ultra-high growth potential..."

"Test Chamber 2012, Subject #549 attempts to fuse, suffers from mental aberrations, and it is recommended that observation continue... Seven days later, the aberrant evolved into a B-class calamity [Fallen Witch], with the ultimate charm ability... Conclusion: The source of the catastrophe has a super spiritual growth, continue the research in this direction... The subject's distortion state tended to be stable, and the sixteenth injection of T3 reagent successfully induced the second aberration, and the subject evolved into an A-class calamity [Dread Witch], and the conclusion was that the source of the catastrophe has growth..."

"Experimental Chamber-3045... The test subject is deformed for the second time and becomes an A-class mysterious calamity [Spell Gambler], and the curse is death..."

"Laboratory 4011... The test subject's second aberration is an A-class assassin calamity [Shadow Thorn], hidden in the shadows..."

"1145.8.16, Summary Report: After fusing cataclysmic samples, each test subject has a different talent to awaken. So far, experiments have confirmed thirty-one directions for the growth of special talents... It has been determined that this cataclysmic source is an epic source card that has never been seen in history. Preliminary conclusion: Fusion of this card requires super high base mental power, dark affinity, and manic mental power... and other conditions that are not fully understood."

"The institute suggests: At present, the probability of fusion distortion of the subject is 100%, and there is a risk of spillover and spread of pollution, and it is recommended that the ban level be changed from 'S-class' to 'T-class' and permanently banned."

「...」

This is what Ji Xun is looking for,

Key clues!
