Xiao Chen quickly pushed the books away, and then saw a trace of lilac light emerging from the wooden board under the books.

This kind of light was exactly the same as the situation at the entrance of the ghost house in the storage room, and Xiao Chen gathered a palm thunder and smashed it down this way without thinking about it.

At the same time that the purple light was dispersed by the palm thunder, the wooden floor on this side also sank deeply, and then the entrance of a secret passage leaked out!

The Wanli Dragon City next to him immediately shouted: "Look! There's a way here! ”

"It must have been opened for us by Qianqian!" Moon Ling's tone was pleasantly surprised, and she was the first to jump towards the entrance of the secret passage.

"Safe below! Come down! Moon Spirit shouted.

I saw Chen Meng whispering to Wanli Dragon City: "That...... Mr. Long...... You ...... first"

However, before Chen Meng finished speaking, the Ten Thousand Miles Dragon City had already jumped down by itself.

Chen Meng was stunned for a moment, and then he also jumped down.

Damn it...... Don't you even understand that ladies first?

Although Yue Ling said that it was safe below just now, Xiao Chen was still not at ease, and the outside was now blocked by Qin Yao's people, so Xiao Chen quickly followed.

Below was a spiral staircase leading straight down, and Xiao Chen felt that this spiral staircase was clearly built within the walls of the library.

I can't imagine that there is still a "cave" in the library of this school.

At this time, Yue Ling and Chen Meng had already turned on the lighting function of their mobile phones, and then they saw Wanli Dragon City and said with a surprised expression: "It's strange, how can there be stairs here!" ”

"It's Qianqian who showed us the way! You can't go wrong! Yue Ling's tone was even more pleasantly surprised: "Let's go down the stairs, there must be an exit to leave!" ”

In fact, Yue Ling's words were actually correct, because the reason why Xiao Chen was able to discover this secret passage was indeed due to Qianqian.

"Qianqian?" Wanli Dragon City said nervously: "Does Qianqian really exist? ”

"Nonsense." Yue Ling said: "I told you everything, the person who provided you with the material said the truth!" Let's go! ”

After finishing speaking, Yue Ling once again took the lead and ran down, and Chen Meng and Wanli Dragon City also followed, and at the same time, Chen Meng said with a thoughtful expression: "Hmm...... I remember that the character Qianqian did appear in Mr. Long's book, and she ...... She seems to have died in an accidental fire, right? ”

"That means you haven't finished reading it at all." Yue Ling said: "Actually, that fire was not an accident at all, but man-made!" ”

"Artificial?" Chen Meng was obviously surprised, she looked at Wanli Dragon City, but Wanli Dragon City still seemed to be immersed in the shock of just learning that "ghosts really exist", and still ignored Chen Meng.

"So, you've seen a lot of Mr. Long's works, haven't you?" Chen Meng continued to ask.

"I've only seen that one." Yue Ling said disdainfully: "What's so good about a plagiarized dog's work, if it weren't for the investigation of Qianqian's affairs, I wouldn't have gone to see it." ”

"And who set the fire?" Chen Meng touched her chin, and the habitual thinking of a scholar seemed to have begun to work in her mind: "I remember that there don't seem to be many characters in that novel, but I really can't guess who they are." ”

"Hmph, of course you can't guess." Yue Ling said: "Because the person who set the fire is basically herself. ”

……

These words not only startled Chen Meng, but Xiao Chen also felt quite surprised.

"She burned herself to death?" Chen Meng exclaimed, "Why! ”

"You'll have to ask that Mr. Dragon." Yue Ling said in a sarcastic tone: "His broken book left a big hole at the end, and said that there would be a second season, but it hasn't been written yet, I guess...... I'm afraid that the person who provided him with the material has not yet told him about the subsequent development of events. ”

Wanli Dragon City was still silent, probably not knowing how to explain.

At this time, the spiral staircase was finally at the end, and in the process of descending before, Xiao Chen had been secretly calculating the approximate height, and now they should be in the height area of the first floor.

Of course, they're still inside the walls.

I saw a square floor tile appear in the corner at the bottom of the spiral staircase, but this was definitely not an ordinary floor tile, because there were nearly twenty knobs on the floor tiles that could be tossed back and forth, and each knob had a different pattern on it.

The style of the pattern is in the form of stick figures, which looks a little strange in this dark and closed environment.

"Oops! It's a dead end! "Wanli Dragon City finally spoke this time.

"Shut up, you!" Yue Ling scolded: "Qianqian won't lead us to a dead end!" There must be an exit here! ”

Then I saw Chen Meng squat down and look at the floor tiles, then raised his hand and said, "This ...... It seems like a puzzle...... We have to solve this puzzle to find the exit! ”

Seeing this, Yue Ling immediately squatted beside Chen Meng, she flicked the knob on the floor tile with her hand a few times, and then saw a slight lilac light coming out of the floor tile, but there was no exit.

"Hmm......" Chen Meng began to think quickly, Xiao Chen could almost see what the gears of thinking looked like when they were running rapidly in Chen Meng's mind.

After about two minutes, Chen Mengcai said: "This puzzle shouldn't be difficult, we just need to restore them to their original areas according to the category of icons." ”

Then Chen Meng pointed to the four corners of the floor tiles and said, "Do you see it?" There are representative patterns here! The upper left corner is the animal, the upper right corner is the tool, the lower left corner is the musical note, and the lower right corner...... Seems to be some kind of obscure ancient spell! ”

When Chen Meng was analyzing the puzzle, it was as if he had changed people, completely losing the cringe he had before.

Yue Ling's interest was obviously aroused, and she once again looked carefully at the floor tiles, and even Wanli Dragon City poked her head over.

Xiao Chen was naturally no exception, now that Chen Meng had interpreted the hints at the four corners, and then looked at the other movable knobs inside the floor tiles, Xiao Chen quickly distinguished four different types of icons from above.

In the case of animals, for example, stick figures of monkeys, birds, and dogs appear on these knobs, so just flip these knobs to the area in the upper left corner.

It's not a difficult puzzle, but it's easy to get confused.

"I can't see that you have such excellent academic performance, and you still know so many extracurricular things?" Yue Ling said approvingly.

Chen Meng seemed a little embarrassed, even in such a dark environment, Xiao Chen found that her face turned red instantly.

I only heard Chen Meng say: "Although this puzzle is not difficult...... But I wonder why such a device appeared here. ”

"Who knows." Yue Ling's tone was still excited: "Let's solve this puzzle first!" ”

Even Xiao Chen could easily identify it, so it was even more impossible that Chen Meng and Yue Ling, the two girls quickly turned the knob on the puzzle to the correct position.

However......

The floor tiles just emitted another burst of lilac light, and then there was no movement!

Wanli Dragon City's face suddenly became difficult to look at, and he felt that this guy looked like he was going to pee his pants.

Xiao Chen was also a little nervous, because the special system main quest just now had not been completed, and it seemed that they had to solve this puzzle completely.

Bite!

Servant Mission: Help the Moon Spirit unlock the entrance to the Ghost House.

Reward: 50 Ghost Points and 5 Opinion Points

The way to the house of ghosts?

Xiao Chen reacted at this time, it turned out that the entrance here was connected to the ghost house!

In addition, since this quest has appeared, it shows that if you don't help, this puzzle may not be solved.

Xiao Chen looked carefully at the floor tiles.

Soon he noticed that there seemed to be something strange about the lower right area of the floor tiles, that is, the "spell" area that Chen Meng had just described.

The color of this area is noticeably different from the other three areas, where the knob icons are fixed in solid black, while the spell area in the lower right area has a lilac tinge.

It's this breath again!

Xiao Chen quietly picked up a palm thunder and tried to hit the spell.

The lilac aura disappeared immediately, and soon the color of the spell in the lower right corner area also returned to its normal black.

However, the Servant mission was not completed.

"Look, the color has changed!" Yue Ling immediately reached out and touched the charm, and then pushed the floor tiles down and sideways, but the floor tiles didn't move at all.

Chen Meng asked Yue Ling not to touch it at first, and then saw herself kneeling lightly on the floor tiles, and then began to beat her fingers on the floor tiles.

"Hmm...... The underneath is empty. Chen Meng said: "The entrance is indeed under the floor tiles. ”

"Then why can't you push it away?" Moon Ling asked suspiciously.

I saw that Chen Meng also tried to press down on the floor tiles, and then said: "It seems that something is under the floor tiles." ”

"You mean...... Is it similar to anti-lock? Yue Ling asked with a frown.

Chen Meng nodded.

"Damn it!" Yue Ling looked up at the spiral staircase above and said, "If you delay any longer, maybe that Qin Yao will find our traces!" ”

Chen Meng was still trying to figure out a way, but no matter how smart she was, it would be impossible for her to remove the blocking things from the other side of the floor tiles.

Xiao Chen first tried the wall piercing technique, but the thickness of this floor tile was still too high, and Xiao Chen's intermediate wall piercing technique could not reach this level for the time being.

Then Xiao Chen thought of the psionic control that he had just learned.

Xiao Chen had already discovered when he used psionic energy control to block Qin Yao and the others just now, this skill was completely using his own psionic energy to control objects from a distance, and psionic energy should not be blocked by obstacles like floor tiles, so ...... Xiao Chen thought that he could use this method to move the obstruction below through the floor tiles?
