() Yun Yi looked at Xia Shishi's compromised appearance, smiled slightly, and didn't have any extra movements, put down the book and read it together.

"The book is white." Xia Shishi flipped through it casually: "What about the title of the book?" ”

"I don't have a title, but the flowers on the cover are beautiful, so I'm more strange and help take it down to see it." Xia Shishi said.

"This school is really, this book is put so high, are you afraid that a short man like us will find out?" Xia Shishi muttered.

Yun Yi looked at her and then compared her head to her chin: "Where are you short?" ”

"Then apart from me, Sister Tang is always there, right?" Xia Shishi said.

"Huh! I'm telling you, you're being attacked physically! Wan Tang said angrily.

"Where is there a human attack?" Xia Shishi spread her hands: "The cutest eldest sister in the team, is there anything wrong?" ”

Wan Tang snorted coldly: "If you don't mention being short, I will still think cute is a compliment." ”

Returning to the book, Xia Shishi spoke first: "Could it be that there is an imprint, and then it is drawn out with a pencil, and there will be words?" ”

"If that's the case, there should be pencils here, and after looking for such a big circle, there are no utensils." Yun Yi thought for a while and said.

"That's right." Xia Shishi nodded.

"Could it be like in the TV series, pointing to the words as soon as you sprinkle water?" Dyson walked over slowly.

"There's no water here, how is that possible?" Xie Kai patted Dyson and said.

"Possibly." Yun Yi thought for a while and said, "Although we are not clean tap water, don't we also have other liquids?" ”

"You mean that?" Xia Shishi picked up a test tube and said.

"Hmm." Yunyi nodded.

"But we can't sprinkle it all at once, can we?" Xia Shishi was entangled: "I didn't see any watering cans either." ”

"Silly, isn't there a dropper?" Yun Yi said, taking out a dropper from the bottle next to him: "Let's try first, if we can't succeed, we'll think of other ways." ”

"Okay." Xia Shishi nodded.

"In order not to affect the next page, we ripped it off to drip it." Yun Yi said and moved.

A blank sheet of paper was easily ripped off. Spread the white paper flat, Yunyi brought out the liquid, and then with a slight drop, the water stain blurred.

Because I was afraid that the water stains would not be in place, I picked a position that was most likely to have notes, in the middle and upper sections.

The water stains blurred, and there was no change, except that they were slightly dyed orange.

"Well, it doesn't seem like there's any clue." Jiang Qi said.

"Don't jump to conclusions." Yun Yi said, and clicked around a few more times, and the water stain expanded more and more, until a faint handwriting appeared.

"This!" Xie Kai said excitedly: "Is this it?" ”

A line slowly appears on the paper.

"It seems that the book should be drawn with a certain figure, otherwise there wouldn't be just one line." Xia Shishi said: "To be on the safe side, we have to fill the paper. ”

"Hmm." Yun Yi agreed, reached out and sucked up some more water, and then dripped on it. It took some time for the imprint to appear, so Xia Shishi tore off the remaining pieces of paper and spread them out in order to drip together.

"I'll tear off four of the four patterns." Xia Shishi said.

"Hmm." Others agree.

With the first experience, the rest of the movements were very fast, and the patterns were slowly revealed.

"In that order, let's try." Xie Kai understood, and then came to the button and pressed, the code door popped open, and this level was passed.

"This trick is really excessive." Wan Tang said angrily.

"But no, there were so many gold nuggets in the last door, and so many stones this time, if I didn't think I couldn't call it, I would really do it." Xie Kai said.

"True." Wantang should be reconciled.

When I opened the door, I was greeted by darkness.

"Huh?" Dyson paused: "Why is it so dark, don't you turn on the lights?" ”

"You're going down the stairs today?" Xia Shishi wondered, they were originally on the first floor, why did they need to come down the stairs?

"It's underground down here." Yunyi said.

"I feel a little wrong...... Xie Kai said.

"I've figured out the routine, as long as I turn off the lights, there will be surprises." Dyson says it's a summary of what happened twice.

"Incisive." Xia Shishi said.

"What then? To go or not to go? Jiang Qi asked with his head out from behind.

Yun Yi lay on the corner of the stairs and looked down to see a faint light: "There is a light source below, we have to go down." ”

If it's not the destination below, how can you turn on the lights for them?

Everyone hesitated for a moment and decided to go down.

"Who's the first?" Everyone hesitated, Xia Shishi seemed to be beating a drum in her heart, and she wanted to step forward, but she was a little scared to go.

She is indeed not a bold person.

"I'll do it." Yunyi said: "Everyone grabs the clothes of the person behind them so as not to separate. ”

"Okay." Everyone responded, and then arranged in order.

Jiang Qi is the most timid one, but everyone has already lined up, and she is the last.

Looking back, the huge laboratory was empty, looking at the darkness in front of me.

"It's just a small staircase...... she comforted herself, reaching out and grabbing Wantang's clothes tremblingly.

Wan Tang only felt that his blouse was gently held, and because of the proximity, he could almost feel the trembling on the girl's body.

Wan Tang thought for a few seconds, and shouted when everyone was just moving: "Stand up." ”

Everyone didn't move: "What's wrong?" ”

Wan Tang let go of Dyson's clothes in front of him, and then reached behind his back to hold Jiang Qi's hand: "You stand in front!" ”

Jiang Qi was flattered: "But you ......"

Wan Tang was generous, and the entire corridor echoed with her heartiness: "I'm fine, I'm not afraid, you go ahead!" ”

Jiang Qi couldn't see Wan Tang's face in the dark, and thanked her in a low voice: "Excuse me, thank you." ”

"Little thing, have you pulled it up?" Wan Tang said.

"Alright." Jiang Qi said softly.

Standing behind her, he gently tugged at her clothes and said to everyone, "Let's go." ”

Yun Yi was at the forefront, leaning against the wall and slowly walking down, little by little, probing the steps under his feet.

There is no light in the center of the stairway, only one at the lowest destination.

After walking below, everyone's vision gradually brightened.

Yun Yi and Xia Shishi arrived first, and they were stunned when they saw the door.

"Such a big door." Xia Shishi said.

"I think it's probably an auditorium or something." Yunyi answered.

"Why does this lock look familiar to me?" The lock on the door is the one I saw upstairs before.

"We haven't found the key to this lock yet." Dyson stepped forward, grabbed the lock, flipped it over, and studied it carefully: "This lock is rusty." ”

"Anyway, there may not be any possibility of hiding a key in this place, right?" Jiang Qi looked around, there was nothing, empty, only the surrounding wall.

Dyson fumbled around the wall to see if there was a mechanism around the wall, so he kicked lightly with his foot below.

Although Xie Kai felt that this approach was very middle-class, he also moved: "I can't let go of the places where I think it's possible." ”

"I think so too." Dyson smiled.

The remaining four stood on the other side and watched the two of them "punch and kick" the wall.

"To be honest, I think it's more like he's somewhere upstairs than a hole in the wall." Wan Tang said.

"Why, the previous keys were all near the door, why are they definitely not near here?" Dyson said.

"Isn't that too easy? There were six of us, two of us, and a wall was found casually. Wan Tang said.

"We were skeptical, but we tried it more comfortably." Dyson said.

Dyson said, kicking his feet, and there was a strange sound under his feet, like the "chirping" sound of something rubbing.

Dyson didn't dare to move for a moment, he stiffened and asked, "What did I kick?" There won't be rats down there! ”

"Probably not!" Yunyi said.

"But what is this?" The side of the foot is not soft, but something like a spring,

Dyson felt that he might have found something terrible, and with a little effort, he kicked it.

The "drop" corridor lit up.

The wall lamps at the feet are not too dazzling, giving everyone a good view of the downstairs.

"I'll just say it, there must be some mechanism." Dyson looked at everyone triumphantly.

"Yes, yes, wood is really smart!" Xia Shishi nodded, she was also thinking about things, and she didn't respond to Dyson for the time being.

"How can this switch be installed underneath?" Xia Shishi asked.

"Let's go up first, go up and have a look." Yunyi said.

A few people had the light shining on them, and they walked quickly, running two steps up a large staircase, and walking upstairs.

"It should be a relatively large key, everyone looks for it carefully." Xia Shishi said.

There are really only experiment-related things in the laboratory, except for books and all kinds of experimental equipment.

"There's no key." Song Lan said.

Jiang Qi finished searching for the place where he was, then looked up and came to the table, where everyone had just looked for the password.

It's okay now, Jiang Qi picked up the dropper and tried to drip twice on the white paper.

Jiang Qi had a playful mentality, and after clicking it twice, the water stains slowly faded away. Because if you want to look better, it's not a color.

Watching everyone skillfully rummaging, Jiang Qi looked down at his "blank paper" again.

Then he was stunned: "This is ......"

The white paper just now can no longer be called a blank paper, and there is an extra paragraph on it.

After Jiang Qi saw it, he immediately sucked out a little more and slept it gently, and gradually a complete paragraph emerged.

"This is the laboratory of the Wenerdi School, because of the gold making matter, this place has become particularly important, I don't think it's a good thing, I am always worried that this place is being targeted by demons, we must take precautions."
