"Hey, don't move!" said the girl, walking over to the third bookshelf and taking down the book that the red dot was shining on.

The boy also walked over, opened the book and looked at it, "It's not this one." ”

"Huh?" the girl was a little disappointed and put the book back down.

However, Mu Xueran found that there were many grid lines on the floor between each bookshelf, and each small grid was only the size of a chess piece.

Mu Xueran picked up the copper piece the size of a chess piece, looked up at Emperor Jiuxiao, and said, "Emperor Jiuxiao, do you think this small copper piece is placed on a small grid on the ground, and the light is reflected from the copper mirror on it to the copper sheet, and then reflected on the bookshelf through the copper sheet." ”

"Hmm. ”

The little couple also heard what Mu Xueran said.

The girl looked at the ground and asked curiously, "But there are so many small lattices here, how can you determine which one it is?"

"Let's look again. ”

After speaking, Mu Xue got up and walked around the bookshelf, but found nothing.

Looking at Emperor Jiuxiao, who was still standing stupidly at the desk, Mu Xueran walked over and said a little speechlessly: "Mr. Emperor, can you have a sense of participation?"

“......”

Emperor Jiuxiao nodded, turned around and walked to the corner, held the candlestick, and spun around, without any reaction.

When the boy saw his movements, he also turned the candlestick closest to him, but he didn't react.

The boy did not give up, and strode to the opposite side, turning the candlestick counterclockwise.

The menorah moved.

And in the next second, the bronze mirror on the wall also moved, moving to the left, revealing the portrait of the princess behind it.

The portrait is complete.

Mu Xueran looked at it carefully, and then took out the magnetic sheet with the pattern.

It fits exactly the small piece on the portrait.

Put the magnetic sheet in the correct position, and in the next second, there was a "bang" sound from the four corners of the wall at the same time, and the candle went out.

"Ah!!h

At the same time, a green glow glows on the floor.

Taking advantage of the light, the girl hurriedly ran to the boy's side, grabbed the corner of his clothes, and hid behind him.

"It's okay, don't be afraid. The boy comforted.

Mu Xueran looked at the lattice on the ground, and between the second and third bookshelves on the left, there was a small black gap in the green grid.

The boy also noticed it, pointed to the gap and said, "It should be that." ”

Mu Xueran nodded, put the small copper piece on it, and then sat down on the chair again.

So the question is, should the bronze mirror on the wall be moved to its original position?

Mu Xueran thought about it and tried it first.

So, turn on the laser pointer, shine it on the copper mirror on the wall, adjust the angle, so that the red light reflects from the copper mirror on the roof to the copper sheet on the floor, and the light passes through the copper sheet, which is projected on the second bookshelf, and counts a book on the second floor.

The girl ran over, took out the book on tiptoe, opened it, and the title page read "Princess Snow and Kiss".

"This is it. The girl was surprised, and then wondered, "Then how are we going to get out?"

The boy walked up to her and looked at the shelf, where there was a dented button underneath the missing book.

At the push of a button, a door opened on the east wall.

The second scene is the princess's bedchamber.

According to the clues found, you need to accurately determine which cup of tea on the table has been drugged, turn the cup, and the door will open.

If you turn the wrong cup, wait another hour.

"There's a box here. The girl pointed to the head of the bed.

It was a characteristic lacquered wooden box, somewhat worn-out, with a combination lock on it, and the code was a six-digit number.

Mu Xueran looked at the little couple and gestured, "Find it." ”

...

In order to make Emperor Jiuxiao feel involved, Mu Xueran decided to pull him together to find clues.

Looking at the little hand that only pulled one of his index fingers, Emperor Jiuxiao hooked his lips silently.

Mu Xueran walked to the wardrobe, let go of the Emperor Jiuxiao, opened the wardrobe door with both hands, rummaged through, and only found a key in a small purse.

At present, there is no box that needs to be opened with a key, so Mu Xueran put it in his pocket first.

"There aren't any numbers here. The girl complained.

Digit... Digit......

A flash of spiritual light flashed, and Mu Xueran asked, "Who is the book just now?"

"Here I am. The boy said, handing her the book.

Mu Xueran flipped through the pages one by one, and when she saw March 22, 116 AD, she turned the book for a moment.

"116322, give it a try. Mu Xueran said.

The girl ran over and said, "I'll come." ”

Turning the gears to align the code with the arrows on both sides, the girl pulled down the lock cylinder and lock body, "It's on!"

Inside the wooden box were several small white pieces of paper, like pH test strips used in the laboratory.

There's also a card underneath that reads-

"Tip: This test strip can detect toxicity by color change. ”

"Let's try it first?" the girl asked.

Mu Xueran nodded.

There were three teacups on the table, and the girl dipped the test strips in the tea in each of the three cups.

The test strips do not change color, turn red, and turn blue from left to right.

The girl pointed to the two cups behind her and said, "That's one of these two?

Mu Xueran lifted her eyelids and said lightly: "Then look for clues." ”

“...... Oh. ”

The girl walked to the dresser, opened a small drawer on the right, inside was a delicate small porcelain bottle, opened the lid, and a black "spider" popped out.

"Ahhh......h

The girl screamed, subconsciously letting go, and the small porcelain bottle fell to the ground, and a small key fell out of it.

The boy ran over, picked up the porcelain vase and key on the ground, looked at the toy spider that popped out of the small porcelain vase, and smiled: "This is fake." ”

"Ahh With that, the girl took a step back.

"Good, good. The boy closed the lid and put the small porcelain vase back in the drawer.

The girl patted her chest, eased up, and glanced at Emperor Jiuxiao with some embarrassment, and the latter didn't even give her a look.

The girl pouted, bent down and opened the cabinet under the dresser, which contained a wooden box.

On top of the box is a 4×4 Huarong Road.

The girl tried to move the small wooden block, but she couldn't even put 1 and 2 out.

I had to ask the other three, "Which of you knows this?"

Mu Xueran walked over, 4×4 Huarong said, she played badly when she was young.

After turning her eyes, Mu Xueran turned her head and said to the Emperor Jiuxiao behind her, "Will you?"

The tone was a little provocative.

Emperor Jiuxiao raised his eyebrows and did not speak.

Walking to the box, Emperor Jiuxiao looked at it for two seconds, and saw that he only had one finger, seemingly moving the small wooden block unhurriedly, and finally completed it in the order of 1-15, and it took less than half a minute.

"Click. The box rang.

Emperor Jiuxiao retreated behind Mu Xueran again.

Mu Xueran smiled and stretched out her thumb to him, and Emperor Jiuxiao looked at her dotingly and rubbed the top of her hair.

The girl opened the wooden box and said in surprise, "Hey? ”

The box is also locked.

"Need a small key. The girl turned her head and said.

At this time, the boy stretched out his hand and spread out his palm, which was a small key in his palm.

The girl happily picked up the key and opened the box, which was a white porcelain bottle with a piece of red paper on which the words "poison" were written.

“......”

This name is so direct, Mu Xue complained in her heart, and then said lightly: "Try it with a test strip, what color will it change when you encounter this." ”

The girl took another piece of clean test strip, put it into the mouth of the bottle, and took it out again, and the white test strip had turned blue.

The girl looked at the cup on the table and said, "It's the third one." ”
