Officer Wang's guess that he is the boss of the end is of course a joke,

"Crayon drawings, windows, little girls..."

Leon stared at the painting, squinting his eyes and thinking for a while, "The window on the painting is a cross window, with brown wooden window frames and transparent glass

And the windows in this room are two casement windows, silver metal window frames, gray frosted glass,

There is only one place where the color is the same..."

Insert slightly.

Leon returned to the window, and each of the two casement windows had a stub, the left window was slightly intact, and the right one was a little rusty, and the missing upper part was too insidiously hidden. The base is glued together.

"The shape of the left and right inserts is different, and the left inserts are ordinary L-shaped metal cylinders.

The top of the right side is slightly rounded, the outside is round, the inside is hollow, and it is a recessed hexagon.

Like a hex screwdriver. ”

With a little force, Leon pulled out an L-shaped hexagonal screwdriver disguised as a plug-in from the base that lacked the upper part.

Li Ang flipped the hexagonal screwdriver with some weight and cursed secretly: "It's too insidious to hide."

The only light source in the room is a long strip of light embedded in a plastic lampshade in the ceiling.

The light here in the window is very dim,

Unless you touch it carefully, you can't find the difference at all. ”

Well, got a hex screwdriver, and then what?

Leon tried to turn the screws at the sink with a screwdriver,

But the tip of that screw was already half broken,

Moreover, the hexagonal screwdriver is a hexagonal concave shape, and the size and shape are not matched, and it cannot be unscrewed at all.

"The screws on the outside of the box-spring bed are too big, and there are no screws on the outside of the metal cabinet, and the only place in the room where you can use a screwdriver is..."

He groaned as he walked to the metal door, pointing his screwdriver at the hexagonal rivet on the door.

Click.

The screwdriver is perfectly embedded,

I turned it vigorously for a while, but I didn't move.

"As long as it matches, there are so many rivets on the door, it is impossible for each of them to hide something."

Leon stretched his fingers and tried the rivets one by one,

Finally, when I tried the seventeenth rivet from left to right under the gate, I felt a difference.

"I can unscrew it!"

Li Ang clenched the hexagonal screwdriver in his heart, turned it slowly, and unscrewed the rivets out little by little.

After the rivet is screwed out, there is an extra narrow hole in the door,

This position is dimly lit, and even if you lie on the ground, you can't see what's inside.

And the gloves are too clumsy to fit in at all.

"Think about it, the tip of a hex screwdriver is magnetic..."

Leon took the rivet from the hexagonal screwdriver, squatted on the ground, and put the screwdriver into the hole left by the rivet, and spun it around for a while.

Jingling.

A crisp sound sounded from the door,

Leon's heart was pounding, and he slowly took out the screwdriver, and sure enough, at the top of the screwdriver, he saw a small key glued to it.

“good。”

Li Ang breathed a sigh of relief and stood up, "Judging from the shape, it corresponds to the keyhole of the main entrance. ”

He walked to the door and inserted the key into the keyhole,

Before I could spin, I heard a "click",

The heavy metal gate automatically slides along the rails on the ground, to the left,

Glide to a certain position and stop moving.

Leon didn't rush out of the door, he propped up the door with his hands, poked his head out and looked around for a while.

The space outside the door is a very spacious stone corridor.

The floor, walls, and ceiling are all made of cyan stone bricks, and the ceiling is embedded with a long strip of light that glows white and is the same as the room. The road has an arc,

Li Ang looked left and right, and found that on the right side of the corridor was a stone wall that had been sealed.

On the left side of the corridor, another metal gate of the same style can be faintly seen, and the stone brick above the door is painted with a capital letter B.

Above the gate where he was located, the letter A was painted.

In the mission log, the words "Phase 2 Mission Objective: Leave Room A" slowly disappeared and was replaced by it

[Three-stage mission objective: Explore rooms B, C, D, E, and F in the corridor]

“... And five rooms?! ”

Li Ang complained with empty eyes: "This time, you don't even write the task reward and task time limit?" Does that mean you're looking at it? ”

Spit and complain, the task still has to be carried out honestly.

Leon glanced at the energy battery on his left arm, and the liquid in the battery was a little less than before.

"Gotta hurry..."

He sighed, reached for the key to the door, but couldn't,

"Once you use it, you can't take it off... Understandably, if a key could open all the doors, there would be no need to do tasks. ”

Leon nodded, returned to the room, and wrapped the strips of rags torn from the sheets around his waist,

Holding crayon drawings and letters in his left hand, and holding a screwdriver in his right hand (this thing is also made of metal, and can barely be used as a weapon),

In order to avoid the door suddenly closing, he also stuck a wooden chair on the guide rail of the door - the wooden chair looked like it was made of wood, but it was so strong that it could not be smashed at all, and it was probably a special item made of alchemy.

After confirming that nothing was missing, Li Ang cautiously walked out of the door, walked along the corridor, and slowly walked forward.

This is a ring-shaped corridor, about four meters wide and three meters high.

On the right side is a stone wall,

At intervals on the left, there is a metal gate, and the stone bricks above the door are painted with the letters A, B, C, D, E, and F in turn.

On the left side of room F, there is another stone wall.

The metal doors of each room are different,

On the door of room B, there is a combination lock composed of numbers and letters.

On the door of room C are a number of bottomless triangles and squares, and below the pattern, there is a pattern of an eye.

The door to room D is partially hollowed out, and inside is a platform that looks like a shrine with the words "4L needed" written on it.

The left side is vacant, and on the right side is a gold-encrusted cup with the word "3L" engraved on the bottom.

On the door of room E, the words 2F2S21M2M3S13T2 are written, and below is a row of twenty-four-letter combination locks.

The door to room F is ordinary, with only one keyhole.

The stone wall on the left side of room F has been partially hollowed out in the middle, and it is in the shape of a cylinder, which looks like it is just enough to hold an energy battery.

“...”

Leon stood at the door of room F and let out a long breath of turbidity,

"Don't be afraid of any puzzle we face, face it with a smile, the best way to eliminate fear is to face it... What a fart!

With so many puzzle systems, are you like letting me die?

Tell you if it weren't for the alchemy here,

I was on the spot,

I forcibly retreated! ”

Li Ang's shout echoed in the corridor, but unfortunately no one responded—Miss Chai was not around, and no one complained about him, "What are you yelling at so loudly!" ”
