"Mmm, I see it," Xiao Tan nodded repeatedly, then added, "What does it mean?"

"Don't know," Xiao Ling replied immediately.

"Uh... okay..." Xiao Tan responded, "I thought you had already solved the riddle..."

"If I had, I wouldn't have said 'come take a look'," Xiao Ling said, narrowing her eyes as she looked at Xiao Tan beside her, "I would have directly revealed the answer to the clue, then in your surprised gazes, I would have娓娓道来 (wěiwěidàolái, explained in detail), the process of solving the riddle, and secretly gloated in my heart."

"Hey hey... that sounds like you're talking about me..." Feng Bujue naturally heard the irony in those words and chimed in.

"Ah... as expected of Teacher Jue, you're still quite self-aware," Xiao Ling retorted, glancing sideways at Brother Jue.

Her veiled criticism was undoubtedly a counterattack against Buu and Oubu's earlier assessment of her.

"Alright... the whole world knows he's a narcissist, there's nothing to complain about," Ruoyu interjected at this time, "Let's focus our attention on solving the riddle."

"Aww--" Xiao Ling stuck out her tongue at Ruoyu, making a face, "Big sis, you're taking his side."

"Where did you see her taking his side..." Feng Bujue's mouth twitched as he replied, "She's just following your meaning, using a more blatant way to mock me once, and concluding this topic with a final verdict..."

"Oh! I get it!" Just as the few of them were chatting idly, Buu, who had been studying the wall, seemed to have seen something again. He said loudly, "This is a constellation chart, right?" Judging from his tone, he wasn't completely sure, so he continued, "Look closely... the sizes of these spots are different, some are as big as sesame seeds, some are as big as mung beans, and some are so small that they're barely visible to the naked eye... maybe, if we isolate a set of spots of the same size and observe them separately, we can see a star chart or something..."

"Wrong..." Feng Bujue interrupted with a serious face, "Although my knowledge of astronomy is average, I'm quite familiar with things like constellation composition..."

"Because you were obsessed with *Saint Seiya* for a while when you were a kid," Xiao Tan interjected at the right time.

"Stop talking nonsense! No one thinks you're mute if you don't speak!" Brother Jue just wanted to show off his knowledge and look cool, but he was instantly exposed by Xiao Tan, so he could only shout to relieve his embarrassment.

"Eh~" Xiao Tan just shrugged after hearing this, making an indifferent expression. And Xiao Ling beside him smiled and patted him on the shoulder, her eyes seeming to say... "Well done."

"Ahem!" Brother Jue cleared his throat, "In short, according to my observation, even if we divide these spots into multiple groups and observe them separately, they can't correspond to any constellation."

"Wait a minute." At this moment, Ruoyu stepped forward, staring at the wall thoughtfully, "I seem to have... seen this kind of composition somewhere..." As she spoke, she had already taken two steps back, "Everyone move aside, let me look at the whole thing from a distance..."

Everyone didn't say much and immediately did as she said.

Then, Ruoyu stood about three meters away from the wall, frowning and thinking...

A full three minutes later, something suddenly flashed in her eyes, and her expression suddenly relaxed: "I understand!"

"I'll be damned... really?" Hearing Ruoyu's words, Feng Bujue was stunned. He couldn't help but think, "I used a brain speed far exceeding ordinary people to analyze those spots in various ways, and even considered factors such as dot matrix diagrams and geometric coordinates on the data level... but still had no clue. And you just stood there and looked at it for three minutes, and you say you 'understand'?"

"Xiao Ling, give me a few bullets filled with gunpowder," Ruoyu said, and immediately began to act.

She took the bullets that Xiao Ling handed over and walked to the wall.

*Crack, crack* - a few light sounds came, this was Ruoyu using her fingers to pry open the bullets...

Then, she dipped some of the gunpowder from the casings with the middle and ring fingers of her right hand and began to smear it on the wall.

"These spots of different sizes do have their own different functions," Ruoyu explained while smearing, "For example, this one marks the outline of a larger pattern; and this one indicates filling with color; and this one... indicates a single line segment."

As she explained, the pattern on the wall became more and more abundant and clear. Before long, all the spots had been covered with black gunpowder, and a complete "painting" was displayed on the wall.

However... the other five people still didn't understand what it was.

"This is... some kind of puzzle?" Looking at the six black patterns of various shapes on the wall (two of them were close to geometric figures, and the other four seemed to be silhouettes of objects, but the shapes were irregular), Brother Jue tentatively asked.

"Can't you all see it?" Ruoyu replied, "This is *Bottle, Glass and Violin*."

"Huh?" The reactions of her teammates were surprisingly consistent.

"Sigh..." Li Ruoyu sighed deeply and explained, "*Bottle, Glass and Violin* is a charcoal and pastel painting painted by Picasso in 1912." She pointed to the wall, "If I were to copy it myself, I wouldn't be able to achieve such a high degree of accuracy, but relying on those spots, we have this in front of us..."

"Don't worry, I estimate that you're the only one in this room who has seen the original work... even if there's a big difference, we wouldn't be able to tell," Feng Bujue interjected.

"So... the clues we have now are... 'bottle', 'glass', and 'violin'?" Xiao Ling followed up.

"Hmm... should there also be 'Picasso' and '1912'?" Buu added.

"Expanding our thinking, we can also derive the clues 'wine' and 'music', right..." Feng Bujue pondered, stroking his chin.

"You're all thinking too superficially..." As she spoke, Ruoyu had already come to Feng Bujue's side and grabbed the latter's clothes, starting to wipe her hands... While wiping, she recited, "From the perspective of 'synthetic cubism', this painting does not take realistic objects as its starting point, decomposing the objects towards basic elements, but takes basic elements as its starting point, transforming basic shapes and blocks into the graphics of objective objects. By abandoning painting and brushstrokes, this pattern obtains a more objective truth. These blocks... on the one hand, show the world outside the painting, and on the other hand, show the unity and independence of the painting's own world through their organic combination."

"Dare to say something we can understand?" Among the five confused listeners, only Brother Jue dared to say this after listening to this passage.

"Okay~" Ruoyu gave Brother Jue a disgusted look, raised her arm and pointed at the wall, "Now, pick up your slingshot and try to 'suck' the pattern on the wall out."
