Officer Wang's guess is a joke, of course,

"Crayon drawing, window, little girl..."

Li Ang stared at the painting, squinted his eyes and thought for a while, "The window on the painting is a cross window, brown wooden window frame, transparent glass

The windows in this room are two casement windows, silver metal window frames, gray frosted glass.

Only one place has the same color..."

Insert a little.

Li Ang returned to the window again, and each of the two casement windows had a little insertion. The left window was slightly intact, and the right one was a little rusty, and the missing upper part was too sinister. The base was stuck together.

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

The top of the right side is round on the outside and hollow inside, and a concave regular hexagon.

Like a hexagonal screwdriver.”

Li Ang used a little force and pulled out the l-shaped hexagonal screwdriver disguised as a plug from the base of the plug-in that lacked the upper half.

Li Ang was confused with the hexagonal screwdriver, which was somewhat powerful, and cursed: "It's too sinister to hide.

The only light source in the room is the long strips embedded in the ceiling plastic lampshade.

The light here in the window is very dark.

Unless you have touched it carefully, you can't find the difference."

OK, got the hexagonal screwdriver, and then what?

Li Ang tried to turn the screws in the sink with a screwdriver.

However, the top of the screw was already half broken.

Moreover, the hexagonal screwdriver is a hexagon that is sunken, and it cannot match the size and shape and cannot be rotated at all.

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

He pondered and walked towards the metal door, facing the screwdriver towards the hexagonal rivets on the door.

Click.

The screwdriver is perfectly embedded,

He turned it hard for a while, but it didn't move at all.

"As long as you can match it, there are so many rivets on the door, it is impossible for each to hide something."

Li Ang stretched his fingers and tried to rivet one by one.

Finally, when I tried the seventeenth rivet from left to right below the gate, I felt different.

"Can open it!"

Li Ang was delighted to hold the hexagonal screwdriver tightly, and slowly turned it, screwing out the rivets bit by bit.

After the rivets were screwed out, there was a narrow hole in the door.

The light at this location is dim, and even if you lie on the ground, you can't see what's inside.

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

"I think, the top of the hexagonal screwdriver is magnetic..."

Li Ang took off the rivet from the hexagonal screwdriver, squatted on the ground, inserted the screwdriver into the hole left by the rivet, and turned it for a while.

Dingdang.

The crisp sound sounded from the door,

Li Ang's heart was pounding. He slowly took out the screwdriver. Sure enough, at the top of the screwdriver, he saw a small key stuck to it.

“good.”

Li Ang breathed a sigh of relief and stood up, "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 he could rotate, he heard a "click" sound.

The heavy metal door automatically slides along the ground guide rails to the left.

Slide to a certain position and stop moving.

Li Ang did not rush to walk out the door. He supported the door with his hands and poked his head out for a while.

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

The floor, walls and ceiling are all blue stone bricks, and the ceiling is embedded with long strips of lights that are the same as the room and are emitting white lights. The corridor has a curve,

Li Ang looked around and found a stone wall sealed on the right side of the corridor.

On the left side of the corridor, you can vaguely see another metal door of the same style. The stone brick above the door is painted with a capital letter b.

The letter a is painted above the gate where he is.

In the task log, the word "Stage 2 Task Target: Leave Room A" slowly disappeared, and replaced by

[Three-stage mission objectives: explore rooms b, c, d, e, f in the corridor]

“...there are five more rooms?!”

Li Ang whispered with his eyes: "Don't you even write the task rewards and task time limits this time? It means you can do it?"

No matter how much you complain, the task must be executed honestly.

Li Ang glanced at the energy battery on his left arm, and the liquid in the battery was less than before.

"It's time to hurry..."

He sighed and reached out to pull out the key from the door, but couldn't pull it off.

"If you use it, you can't remove it... It's understandable that if a key can open all the doors, you won't have to do the task."

Li Ang nodded, returned to the room, wrapped the strip of cloth torn out of the sheets around his waist.

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

In order to prevent the door from suddenly closing, he also used a wooden chair to jammed the guide rails of the door - the wooden chair looked made of wood, but it was very strong and could not be smashed at all. It was probably a special item made by alchemy.

After confirming that there was no omission, Li Ang walked out of the door carefully and walked slowly along the corridor.

This is a circular corridor, about four meters wide and three meters high.

On the right is a stone wall.

Every distance on the left, there is a metal door. The stone bricks above the door are painted with six letters a, b, c, d, e, f in turn.

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

The metal doors in each room are different.

On the door of room b, there is a password lock composed of numeric letters.

On the door of room c, there are some triangles and square patterns without bottoms, and below the pattern is the pattern of an eye.

The door of the room was hollowed out, and inside was a platform that looked like a shrine, with the words "needed 4l" written on it.

There is a vacant place on the left, and a gold-inlaid cup is placed on the right, with the words "3l" engraved at the bottom of the cup.

On the door of room e, the words 2f2s21m2m3s13t2 are written, and below are a row of twenty-four letter password locks.

The door of the room f is ordinary, with only one keyhole.

F The middle of the stone wall on the left side of the room was hollowed out, in the shape of a cylindrical body, and it looked like it could be equipped with energy batteries.

“…”

Li Ang stood at the door of room F and exhaled a long breath of turbid air.

"Don't be afraid of any puzzle we face. Face it with a smile. The best way to eliminate fear is to face it... No, that's it!

Do you think you're letting me die with so many puzzle systems?

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

I'm on the spot,

Then he forced himself to retreat!"
Chapter completed!
