You're the one who's constipated! Zhang Yuanqing gave her a solid thump on the shoulder, pressed the headset to her ear before Sun Miaomiao could retaliate: "I think I've got a good sense of what's going on." The underground team was instantly energized, though they didn't show it—some pretended to sip coffee, others to gaze at the scenery—steadily focusing on Yuan Shi Tian Zun's explanation. "I suspect the armored personnel made adjustments at the stone gate..." Zhang Yuanqing outlined his hypothesis, omitting his own headache and merely mentioning he had a device to activate memories. That makes sense! The team members suddenly understood. With a subtle relief in his heart, Tian Xia Gui, who had been most concerned about the armored team's potential use of undetectable, unintelligible monitoring methods, now felt more confident—his own position would no longer be so passive. "Based on Xue's death in the Xia dynasty, we can infer that the armored person entered the Jiāorén Lake to check for traces during the late night hours—during the day, they have classes and are busy with many people around, and even in the evening, the same situation applies. Only during the quiet late night, when everyone is asleep, is it possible to go unnoticed. If it were me, I would also choose that late night hour." Tianxia Guihuo lowered her head and sipped her coffee. "Yuan Shishen entered the underground palace twice—one in the morning, one in the evening—perfectly avoiding the crowds." Sun Miao Miao pretended to gaze blankly at the ceiling. "Therefore, the likelihood that the armored person is a Star Official is quite low. The Star Observers and Yuan Ting are not the armored ones." Star Officials have attendants and undead servants who monitor the stone gate at all times, so they don’t need to enter the lake personally. Yuan Shishen himself is a prime example. Xia Hou Ao Tian said, "We still have three questions left—do either of you have any ideas? By solving these three, we’ll be able to clarify the entire sequence of events "I still feel something's off," he mused, speaking directly through thought. "Imagine if I were a warrior in armor—how would I act? I'd conduct a secret investigation, pinpoint the target, and then strike. Instead, you've killed someone and made it public knowledge—this is a move that results in mutual losses." Zhang Yuanqing was about to speak when the Red Chicken Brother slammed his palm on the table, exclaiming, "Enough! Your lack of energy is beginning to drive me crazy." "The old dean shook his head: 'No, quite the opposite—these people actually have things to verify. The ones who stayed alone in their rooms are the ones who cannot be verified, because no one can confirm whether what they say is true or a lie.' He paused, lifted his teacup, and took a sip before continuing: 'Next, we need to verify two points. First, according to the records of the students in the canteen, Zhu Mingxu left midway and returned only after about fifteen minutes. Second, did the Yuanshixian and Zhao Chenghuang stay overnight? Based on my regular observations, whenever Red Chicken hosts an event, Yuanshixian has never missed a single one.' 'Starlight, take the lie-detection equipment and go speak to them.' Starlight, the observer, nodded and rose to leave the conference room. The old dean then turned to the remaining teachers: 'Now, think carefully about the motives behind the armored person's killings...' Everyone was stunned by Red Chicken, staring at him in silence, completely at a loss as to why this rough-fire demon was acting so strangely." Hong Ji brother complained, "I can't take it anymore! From the moment we entered the café until now, no one has spoken a word. 'Is it really that big a deal that one of the students has passed away? We've only just met, haven't we? Of course, I'm not thrilled about the loss—people do tend to feel down when someone dies—but life has to go on, right? So, I propose we head to the canteen for lunch, have a bowl of fresh, delicious hot rice soup, and after that, our spirits will surely lift.'" He thought we were all grieving. Everyone stared at him in silence. "Why are you all looking at me like that? Did I say something unreasonable?" Hong Ji brother frowned. "Ah, yes, yes—absolutely reasonable!" Everyone nodded in unison. I really admire Hong Ji brother's straightforwardness. Zhang Yuanqing smiled and said, "We're just still trying to figure out who the murderer is. We'll be here for another three days, so it's best to identify the culprit as soon as possible so that everyone can feel at ease." "That's true," Hong Ji brother agreed, nodding. "Then, do you have any suspects?" "Miss, I think you're really trying to fight. I'm a staunch advocate of gender equality—never soft on women, especially not when it comes to someone with a close relationship to Yuan Shi Tian Zun." Red Chicken Brother picked up on her sarcasm, just as the dean had. "Who's even having a close relationship with Yuan Shi Tian Zun?" Sun Miao Miao reacted fiercely. "Yes, but don't worry too much—The Armored One won't easily reveal this, since he's also after the treasure. By the way..." Zhang Yuanqing's words were once again interrupted, this time not by Red Chicken Brother, but by the Stargazer. Avoiding the lie-detector gadgets in the morning relied entirely on Zhao Chenghuang's cleverness—this time, however, they were directly confronting each other, asking one-on-one questions, and repeating a similar approach; even a fool could see the issue. Could we resolve it with vague language? For instance, "I've been doing secret things together with Zhao Chenghuang"? No, such language wouldn't hold up—people wouldn't be treated as fools. If they asked for specifics, I simply wouldn't know what to say. Zhang Yuanqing's thoughts surged, yet his expression remained perfectly composed. He glanced at the small brown horn resting on the table and said firmly, "Starlight Teacher, before I answer your question, you need to answer me one." Starlight Observer looked deeply into his eyes and said, "Go on." "Why is the Director so concerned about what the students did last night?" "Since the lie-detector isn't yielding results, we can only gather information and possibly uncover clues," said the Starlight Observer. "In my opinion, your questions shouldn't have focused on what happened last night, but rather more precise ones—like: How closely connected are we with Xia Xiaojie? Have we developed any feelings for her? Do we have any private interactions with her?" Zhang Yuanqing smiled. "Don't these questions have better targeting?" While delaying time, he was gradually entering the body of Yin Yao, assuming the pale countenance. Due to the unexpected incident this morning, he believed there would likely be more such occurrences in the coming days, so he secured the Lady Yin's agreement to freely enter and exit her body for the next three days. "Good idea," the Star Observer nodded. "Then just answer all these questions." Zhang Yuanqing smiled, though there was not a single trace of warmth in his eyes. "Your attitude is quite frustrating. I'm not even a suspect. Pay attention to your tone—should this be any other place besides the academy, I'd have already pinned you to the ground and pounded you senseless, even if you're a Level Five." "The stargazer said coldly, 'Please hold your prop and answer my questions.' Yuan Shǐ Tian Zun clearly intends to use emotional outbursts as an excuse to evade the truth-testing—this won't do. These teachers have all been frontline practitioners themselves; such a mediocre tactic would be immediately obvious to them... Tian Xiang's brows furrowed in concern. The other members of the Earth Palace team also felt a weight settle upon their minds. At that moment, they observed Yuan Shǐ Tian Zun lift the brown horn and speak calmly, 'I gave Zhao the Spirit Scroll manuscript.' Then, with a cold smile, he tossed the brown horn onto the table. 'Stargazer, now it's your turn to answer my questions.' The stargazer watched the still-unresponsive horn, first frowning, then suddenly realizing. Last night, Zhao and Yuan Shǐ Tian Zun had conducted a transaction—its content was unmistakable: precisely the floating incantation technique Yuan Shǐ Tian Zun had demonstrated on Jī Xīn Island. For the star official, that was indeed an irresistible appeal—one he had long cherished. The celestial observer recalled the events of that day and concluded that Lord Zhao's pursuit of a trade was both reasonable and logical. "Now I understand. I will convey this to the abbot." Excellent work! Beneath Lord Zhao's composed demeanor lay a surge of genuine surprise. Yuan Shǐ Tian Zun's maneuver was truly masterful—he first displayed profound displeasure and anger, then skillfully resolved the matter by weaving together the exchanges among the three of them on Jīxīn Island. The celestial observer would not harbor suspicion, as Yuan Shǐ Tian Zun had indeed presented him with a sacred scroll manuscript, and as someone present at the scene, he only needed a slight mental connection to grasp the full significance. The others, including Tianxia Guihuo, were utterly bewildered, unable to comprehend how Yuan Shǐ Tian Zun had so effortlessly won the celestial observer's trust. "Master!" Zhang Yuanqing spoke up, calling the celestial observer back before he began to depart, and asked, "What are your thoughts on the murderer?" The stargazer remained silent for several seconds, then murmured, "I suspect the murderer is the same person who made the mysterious visit to the Jianren Lake on the first night of the new semester." Zhang Yuanqing raised an eyebrow, "How do you know that?" "Because both the lie-detection devices and the insight technique failed—such abilities are quite rare, and not everyone possesses them," the stargazer explained. "Rare, so they do exist, correct?" Zhang Yuanqing thought for a moment before replying. "Do you know of any ability that can evade both lie-detection and insight techniques?" The stargazer hesitated. Seeing this, Zhang Yuan清 turned to summon the waiter, "Please serve the teacher a cappuccino." Observing Yuan Shǐ Tian Zūn's demeanor, the stargazer sighed and sat down, glancing at Zhao Chenguang, then at Yuan Shǐ Tian Zūn, and whispered, "I mentioned this on the island, didn't I? The Tai Yin symbolizes secrecy." "Zhang Yuanqing furrowed his brows: "But there are only so many celestial officials on the island, and among them, only Zhao Chenghuang specializes in the Yin." Zhao Chenghuang glanced at him and said calmly: "My Yin energy hasn't yet reached its full maturity; it still can't shield against lie-detection devices. Sun Miaomiao specializes in the stars, while Yuan Ting has yet to earn sufficient merit to receive the secret cultivation techniques." "Then it's not Yin at all," Zhang Yuanqing shook his head. "You haven't grasped my point..." the sky-observer hesitated again. "A fully perfected Yin energy doesn't only allow one to remain undetected—it can also be bestowed upon others. When I was still a frontline practitioner, I once pursued a fraudulent physician who could perform divination. The temple elders granted me their hidden Yin power as a reward. As a result, any actions directly linked to me became undetectable through divination." The underground team fell into thoughtful silence. The power of the Great Perfection of the Moon can bestow hidden strength upon others... To kill Xia Chao Xue without hesitation for the sake of what lies behind the stone gate—such decisiveness is unlike that of a typical official saint, as it inevitably fractures relations with the official establishment. Yet, only someone outside the official sphere could gain entry into Qin Feng Academy, and figures like Hong Ji Ge are truly unique. Yet, being within the official ranks, yet clearly not embodying the true spirit of official practitioners—what on earth is going on? Dark Night Rose?! A mental storm erupted in Zhang Yuanqing’s mind. At that very moment, he suddenly resolved a long-standing mystery—why, every year during the official health screenings, members of Dark Night Rose consistently escape detection. The leader of Dark Night Rose is a Night-Wanderer specialist, of exceptionally high standing. She (he) bestows hidden strength upon key figures within the organization—powers that would surely go undetected during the annual health assessments. Everything now makes perfect sense. For heaven’s sake, Dark Night Rose members have infiltrated the cohort! It's no surprise he acts so resolute when it comes to killing—this is precisely the style of the Night Rose's double agents. The Night Rose members operate within official institutions and among the noble families of the Spirit Realm, and it's only natural that they'd be aware of the hidden missions. Hey, why's this so coincidental? Why now, of all times? I'm just damn unlucky... Well, maybe I'm not that unlucky at all. The Star Official can observe the course of all things through celestial observation. If the leader has been eyeing the hidden missions, he likely studied the stars and sensed the right moment had arrived. Thus, he instructed his double agents embedded within the official circles to attend this training session. The armored agent's reconnaissance, the application of invisible materials, and nightly monitoring of the stone gate—all perfectly explainable. Another Night Rose. What a persistent fate this organization has with me! Zhang Yuanqing took a deep breath and looked toward the celestial observer, saying, "Teacher, we need to talk. I've already deduced the hidden identity of the killer." His first reaction was to inform the dean and work with the administration to apprehend the members of the Night Rose hidden within the academy.
