"Hey! Are you guys alright?" Xiao Tan's shout came from above the floor just two seconds after the entrance closed.

"We're fine so far," Feng Bujue quickly responded.

Actually, for the two in the wine cellar, the closing of the entrance didn't bring much fear... because the headmaster's office above, like this place, was lit only by flashlights. So, even with the barrier closed, visually, they wouldn't feel much of a change in darkness. It was just that "bang" that was a little startling. Of course... it wasn't going to scare Feng Bujue.

"Brother Jue! That barrier closed by itself!" Xiao Tan shouted again in the next second.

"Yeah... figured," Feng Bujue replied listlessly.

That much was obvious; after all, Xiao Tan and the others couldn't have closed the barrier.

"The remote control seems to be useless," Xiao Ling's voice rang out a few seconds later.

She had clearly tried to open the entrance again with the remote, and failed.

"Hmm..." At this moment, Gui Xiao, who had squatted down to examine the entrance, added, "Touching this barrier gives the prompt [Sealed by a dark force]."

Everyone understood what this prompt meant—the way to open the entrance had changed.

"Heh... it looks like we'll have to split up from here," Feng Bujue chuckled and said to his teammates through the floor, "Anyway... go check around again and see if there are any flags we can trigger."

Speaking of this, the first thing Xiao Tan and the others thought of was that "mysterious man on the playground."

So, the four quickly walked to the window and looked outside again.

And the result...

"Brother Jue!" In less than ten seconds, Xiao Tan ran back above the entrance and shouted to the bottom, "That person is gone!"

Almost as he shouted these words, suddenly, from the darkness outside the headmaster's office... came a "whoosh—" sound.

"Eh? That just now..." Jue-ge naturally heard the sound and said, "...Could it be the sound of a sliding door?"

"Uh..." Xiao Tan paused for a second and replied, "Seems like it."

There was no doubt that the source of the sound wasn't on the second floor, because the second floor only had two rooms (the headmaster's office and the storage room across from it), and both had hinged doors. Therefore... that sound must have come from downstairs.

"What should we do? Should we go down and take a look?" After a brief silence, An Yueqin asked.

"Of course, this is obviously the main storyline," Feng Bujue replied from under the floor. "Anyway, the four of you have already completed puzzles that 'only specific characters can solve', so it doesn't matter if you get a lunchbox next, so... go ahead and go without worry."

"What about you?" Xiao Tan asked again. "Do you want... someone to stay here to support you?"

"Absolutely not," Feng Bujue replied decisively. "Leaving someone here to wait is the same as leaving a flashlight here to waste power... how could that be possible?" He paused and added, "You guys go explore yours, we're fine; when you've dealt with the storyline outside, maybe we can get out."

He was right. At this moment, each team happened to have two flashlights; in the wine cellar, Feng Bujue was holding Xiao Tan's flashlight, and Ruo Yu was holding her own; and outside, Xiao Ling and An Yueqin were each holding their own flashlights. The power of these four flashlights wasn't the same, but all of them were already mostly drained... If nothing unexpected happened, these four flashlights would go out one by one in the next ten minutes...

"Okay... we understand," Xiao Tan and the others reached a consensus after a few seconds. "Then... Brother Jue, be careful, we'll go first."

"Hurry up and go, don't dawdle," Jue-ge replied with a tone that showed no sense of crisis, but rather a hint of impatience.

Therefore, the four outside didn't have any psychological burden; they immediately left the headmaster's office and headed back to the first floor.

And Feng Bujue and Li Ruo Yu were trapped in that narrow secret wine cellar...

"Is that really okay?" About ten seconds later, Ruo Yu, who had confirmed by hearing that everyone had gone far away, finally spoke, "You should have noticed too... from the moment the entrance was closed, this place..."

"I know," Feng Bujue interrupted. "But I don't think there's any need to let them know too..." He paused for half a second and added, "Even if I told them 'the air in the wine cellar is almost like gaseous alcohol', there's nothing they can do, so it's better not to say anything... so as not to give them unnecessary pressure."

Obviously, they both realized... the situation triggered after the entrance was sealed wasn't a "change in light", but a "change in air"; the former would at most create some sense of terror, but the latter... was a physiological effect.

"So... what should we do now?" Ruo Yu asked. "Are we really just going to wait... until the entrance opens by itself?"

"It's rare to have such conditions, how about we flirt a little while we're drunk?" At this time, Feng Bujue turned his head and used the flashlight to shine his face from bottom to top, revealing a... um... how to describe it... the word "lewd smile" seemed more appropriate.

"Sure~ You start~" Unexpectedly, Ruo Yu gave a positive response, but... the expression on her face was dead fish eyes plus a poker face, and the tone was a sarcastic and stilted reading.

"Hehe... no problem~" Feng Bujue laughed a few times again, and then used the tone of a hooligan teasing a good woman on the street in a TV series, "Beauty, are you alone?"

"Yes," Ruo Yu replied.

"Hehe..." Feng Bujue said again, "Do you want to find a place with me where no one is around to talk about life?"

"Are you talking about what we're doing right now?" Ruo Yu replied.

"Uh..." Jue-ge couldn't handle it a bit. Whenever he was in a crisis, he would instinctively use a coping measure—further lowering his bottom line, "Hehe... well, why don't we just do something wet and shy."

"Spit in your mouth?" Ruo Yu continued to use her cold tone and sharp on-the-spot reaction to attack Jue-ge's shameless words and actions.

"Ha—" Finally, Jue-ge sighed, "Okay, okay~ I'm not kidding anymore..." When he said this, he finally returned to a serious (relatively speaking) attitude, "Let's continue moving forward."

After saying that, without waiting for Ruo Yu to respond, he turned around and continued forward, walking to the wall on the other side in a few steps.

"There's still a road over there?" Ruo Yu asked as she followed.

"There's no road, but there's a pretty obvious puzzle..." Jue-ge said, slightly turning his body to reveal a row of wine racks in front of his side.

This wine rack had three layers, with five wooden slots on each layer. At this moment, there were five bottles of wine in these fifteen wooden slots, two bottles in the first row, both located on the far left; one bottle in the second row, located in the fourth slot; and two bottles in the third row, located in the first and fifth slots respectively.

"This..." Ruo Yu reacted quickly, "Is this echoing the 'Hanoi Tower graffiti' hint in the women's restroom?"

"It should be," Feng Bujue replied.

"But... you can solve this puzzle too," Ruo Yu continued. "Could it be that Togashi is a girl in the setting?"

"How could that be... then there should only be two hints in the men's restroom," Feng Bujue replied. "In my opinion... it's because it doesn't matter who solves the hint itself." He paused for a second and then said, "The tic-tac-toe hinted at by Tic_Tac_Toe and the hint 'watch your step'... weren't they both solved by me?"

"So?" Ruo Yu signaled him to continue.

"So... a hint is a hint, and it doesn't matter who discovers the connection," Feng Bujue said. "The key is... in the place indicated by the hint, there should still be some kind of problem that only specific characters can solve." He immediately gave an example, "For example... the place where the 'Tic_Tac_Toe graffiti' hint is used needs someone who can play the piano; the place where the 'be careful of the pool' hint is used needs someone who can dissect; and the place where the 'watch your step' hint is used needs someone who is 1.6 meters tall..."

"Hmm..." Ruo Yu heard this and thoughtfully replied, "That makes sense... the place where the 'pattern' hint was used just now needs someone with strong mathematical abilities."

"Right," Feng Bujue nodded and continued, "The things pointed to by the hints are not necessarily things that need specific skills to deal with, but... when such things appear, it means that a puzzle that needs specific skills to deal with is nearby."

"Understood," Ruo Yu said, looking at the wine rack again, "In that case, you should handle this 'Hanoi Tower' puzzle."

"That's what I thought too," Feng Bujue said, "Help me keep an eye on things, in case some monsters pop out of the surrounding walls, ceiling, floor, or even the wine bottles while I'm moving the bottles, you help me smack them."

"Okay," Ruo Yu calmly agreed to the request.

Afterwards, Feng Bujue prepared to start moving the wine bottles.

However...

"Eh?" As soon as he picked up the first bottle of wine, he froze with a suspicious look on his face.

"What's wrong?" Ruo Yu asked.

Feng Bujue didn't reply, he just silently turned the wine bottle halfway around, showing the label on the bottle to Ruo Yu.

"This is..." On the label that came into Ruo Yu's view, there wasn't a single word... no brand, name, description, year... nothing; what was printed on the label was actually a painting.

"Heh..." After thinking for a moment, Ruo Yu sneered, "So that's what's going on."

"Looks like that's what's going on," Feng Bujue shrugged, put the wine bottle back on the wine rack, and stepped aside from behind Ruo Yu, giving up his position in front of the wine rack.

Ruo Yu didn't waste any time, taking two steps sideways, she picked up the five bottles of wine one by one and began to identify the paintings printed on the bottles.

…………

Here, let's briefly talk about the rules of the so-called "Hanoi Tower game."

This game originated from an ancient Indian legend, and the content of the legend will not be described in detail here... Simply put, the rules are that three pillars are set up first, and a number of discs are placed on one of the pillars, and the size of the discs must be from small to large from top to bottom; and the goal of the game is to move all the discs on one pillar to another pillar, with the premise that only one disc can be moved at a time, and large discs cannot be placed on top of small discs.

This is not a very complicated game, and most people can quickly find the rules of movement and complete the movement in the shortest number of steps.

In the example in front of you, the three layers of the wine cellar are equal to the three pillars, and the five bottles of wine are equivalent to the five discs from small to large; but the problem is... how should this "size" be distinguished?

The reason why Jue-ge thought he could handle this puzzle just now was... he thought he could easily distinguish the "size" represented by the five bottles of wine.

But, as mentioned above, when he saw the bottles, he realized that the information recorded on the bottles was something he couldn't decipher.

If the information given here was words, numbers, codes, or something like that, or if there were subtle differences in the volume and shape of the bottles themselves, Jue-ge would definitely be able to solve it; unfortunately... five paintings were printed on the five bottles of wine.

Needless to say, only Ruo Yu, whose family runs an art gallery, could sort the five bottles of wine in front of such a hint.

…………

"Okay, I've confirmed it," In less than two minutes, Ruo Yu spoke again, and stretched out her slender fingers to gently tap the wine bottles in front of her, "There are a few small traps in here... At first I thought it was arranged according to the year of creation, but I quickly discovered that the creation year of this 'Beauty of the Harem' by Dousse is unknown, and it can only be determined that it was painted in the second half of the nineteenth century; this has a certain conflict with 'Alyonushka', which was released in 1881, and it is impossible to determine which one came first and which one came later..."

While explaining to Jue-ge, she was already moving the five bottles of wine.

"After that, I considered the size, genre, style, and even the creator's situation at the time, etc... but some of the information exceeded my knowledge reserve. So I changed my thinking and finally discovered the problem..."

At this point, she had placed all five bottles of wine in the five slots on the top layer of the wine rack.

Just as her hand left the mouth of the bottle, there was a "click" sound, and a sound of some kind of mechanism starting up came from inside the wine rack.

Immediately afterwards, the system prompt also came: [Transfer five bottles of wine to the bottom layer of the wine rack in the correct way and order].

"It seems I was right..." Ruo Yu said after hearing the sound, "The original position and distance of the five bottles of wine hinted at the fact that these five painters were in three different eras and the order in which they died; therefore... the basis for arranging these five bottles of wine is the 'lifespan' of the five painters."

After saying that, without waiting for the bewildered Jue-ge to make any expression, she began to move the wine bottles according to the rules of Hanoi Tower.

In fact, Ruo Yu was also a little anxious in her heart, because... after staying in this "alcoholic" place for a while, she was indeed a little drunk. Not to mention the blush on her cheeks, even her head was a little dizzy... this was not a good sign.
