"You're constipated!"

Zhang Yuanqing flicked her forehead. Before Sun Miaomiao could retaliate angrily, he pressed his earpiece and said, "I think I know what's going on."

The dungeon team's hearts lifted, but they didn't show it on their faces, either pretending to drink coffee or pretending to admire the scenery, focusing intently on waiting for the answer from Yuanshi Tianzun.

"I suspect the Armor Man tampered with the stone door."

Zhang Yuanqing explained his speculation, concealing his headache and only saying that he had a prop to activate memories. So that's how it is! The dungeon team understood. Tianxia Guihuo subtly relaxed, as he was most afraid of the Armor Man having undetectable and incomprehensible monitoring methods. If that were the case, they would be very passive. "Based on Xia Chaoxue's death, it can be inferred that the Armor Man sneaked into Jiaoren Lake to check for traces in the late night. During the day, they have classes, and there are many people around, making it difficult to act. The same is true at night. Only in the late night, when everyone is asleep, is it suitable to sneak into the lake. If it were me, I would also choose the late night when I wouldn't be discovered." Tianxia Guihuo lowered his head and drank his coffee. Yuanshi entered the dungeon twice, once in the morning and once at night, perfectly avoiding detection. Sun Miaomiao pretended to stare blankly at the ceiling, "In this way, it's less likely that the Armor Man is a Star Official. Star Explorer and Yuan Ting are not the Armor Man." Star Officials have spirit servants and Yin corpses, so they don't need to sneak into the lake themselves. They can monitor the stone door situation at any time. Yuanshi Tianzun is an example. Xiahou Aotian said, "There are three questions left. Do you have any ideas? If we solve these three questions, we'll understand the whole story. I still feel something is wrong..." He thought for a moment and spoke telepathically: "Imagine, if I were the Armor Man, I would choose to search secretly, lock onto the target, and then take action, instead of killing someone and making it known to everyone. That's a lose-lose strategy." Zhang Yuanqing was about to speak when Hongjige slammed the table and shouted angrily, "Enough! Your negativity is unbearable!"

Library, conference room. The white-haired old dean sat at the end of the conference table, with a stack of thin papers in front of him. He looked around at the teachers at the table and said in a deep voice, "In the entire academy, there are 11 people who can corroborate each other's alibis for the late night. Nine of them were eating grilled skewers and drinking congee at the cafeteria, organized by Hongjige. They ate and drank until 1:30 a.m. The other two are Yuanshi Tianzun and Zhao Chenghuang. Everyone else was in their dorm rooms, resting early."

"Those people can be ruled out as suspects?" Huo Mo Luolesheng rumbled.

The old dean shook his head: "No, those people are the ones we can investigate. It's the people in the solitary rooms that are impossible to investigate, because no one can verify whether they're telling the truth." After a pause, he picked up his teacup and took a sip, saying, "Next, we need to verify two things. First, according to the cafeteria students' statements, Zhu Mingxu left midway and returned after ten minutes. Second, Yuanshi Tianzun and Zhao Chenghuang stayed together all night? According to my usual observations, Hongjige's treat never misses Yuanshi Tianzun. Star Explorer, take the lie detection device and go ask them."

Star Explorer nodded and left the conference room.

The old dean looked at the remaining teachers and said, "Next, everyone think about the Armor Man's motive for killing."

Everyone was startled by Hongjige, staring blankly at him, not knowing what this crude Fire Demon was acting out.

Hongjige cursed, "I can't stand it anymore! You haven't said a word since we entered the cafe. So what if a student died? We've only known each other for a few days! Of course, I'm also very unhappy about the death, but life has to go on, doesn't it? I suggest we go to the cafeteria for lunch and have a bowl of fresh and delicious congee. We'll feel better after drinking it."

He thought we were sad? Everyone stared blankly at Hongjige.

"What are you looking at me for? Am I wrong?" Hongjige glared.

"Ah, yes, yes, you're right, you're right." Everyone nodded in unison.

"I admire Hongjige's simplicity..." Zhang Yuanqing smiled and said, "We're just wondering who the killer is. After all, we still have to stay here for three days. Finding the killer as soon as possible will put everyone at ease."

"That's true." Hongjige nodded. "So, have you figured out who the killer is?"

"Definitely not you," Sun Miaomiao huffed.

"Little girl, I think you want to fight. I'm a staunch supporter of gender equality. I never go easy on women, even if you have an ambiguous relationship with Yuanshi Tianzun." Hongjige understood her sarcasm, just like the dean's sarcasm earlier.

"Who has an ambiguous relationship with Yuanshi Tianzun?" Sun Miaomiao reacted strongly.

At this moment, Yuanshi Tianzun's voice came through the earpiece. "Xiahou Aotian's doubts are related to why Xia Chaoxue was killed. Perhaps there's another reason for the killer to kill Xia Chaoxue. But no matter what, now that the stone door has been opened, the matter has been discovered. We must find the killer and kill him (her), to prevent him from leaking this information."

Tianxia Guihuo narrowed his eyes, with a hidden murderous intent: "We must find him and kill him before the academy teachers do."

Zhao Chenghuang and Xiahou Aotian also had resolute killing intent in their eyes. They would do anything to protect this treasure.

"That's right, but don't be too nervous. The Armor Man won't easily reveal this matter, because he's also after the treasure. Also..." Zhang Yuanqing's words were interrupted again, but this time not by Hongjige, but by Star Explorer. This Star Official, with ordinary features but an ethereal and noble aura, entered the cafe.

"Everyone looked over. I asked around and heard from the students that you were in the cafe."

Star Explorer walked to the table, gracefully sat down, looked at Yuanshi Tianzun and Zhao Chenghuang, and said, "The dean asked me to ask you, what were you doing last night?"

It's a good thing Star Explorer isn't a scout, otherwise he would have been able to see the dungeon team's momentary solemn expressions.

"Damn it, will this ever end? Keeping this lie detection device is a disaster..." Zhang Yuanqing thought with a start. He looked towards Zhao Chenghuang, whose expression became even colder. Tianxia Guihuo, Xiahou Aotian, and Sun Miaomiao silently looked over, their calm exteriors hiding furiously operating brains. Avoiding the lie detection device in the morning relied on Zhao Chenghuang's cleverness, which was a fluke. This time, they were being directly confronted with it, a one-on-one question. Another similar operation would be obvious to even a fool... Use ambiguous rhetoric to resolve it? For example, Zhao Chenghuang and I did something secret together? No, this kind of rhetoric wouldn't fool anyone. We can't treat people like idiots. If they ask what it was specifically, I won't be able to answer at all. Zhang Yuanqing's mind was racing, but he remained outwardly calm. He glanced at the small brown horn placed on the table and said in a deep voice, "Star Explorer, before I answer you, you need to answer a question first."

Star Explorer gazed deeply: "Go ahead."

"Why is the dean so concerned about what the students did last night?"

"Since the lie detection device can't get results, we can only try to gather as much information as possible, perhaps finding a clue," Star Explorer said.

"Then I think your question shouldn't be what we did last night, but some more precise questions, such as: What is our relationship with Xia Chaoxue? Did we develop feelings for her? Did we have any private contact with her?" Zhang Yuanqing smiled. "Aren't these more targeted?"

He stalled for time while entering Princess Yinyao's body, activating the white face ability. Because of the incident in the morning, he believed there would definitely be similar encounters in the future. Therefore, with Princess Yinyao's consent, he could freely enter and exit her body for the next three days.

"Good idea." Star Explorer nodded. "Then answer all of these questions."

Zhang Yuanqing smiled, but there was no hint of a smile in his eyes. "Your attitude is making me very uncomfortable. I'm not a suspect. Watch your tone. If this weren't the academy, I would have pinned you to the ground and beaten you, even if you're Level 5."

Star Explorer said coldly, "Please hold the device and answer my questions."

Yuanshi Tianzun is planning to use an emotional outburst as a reason to get away with it, refusing this lie detection? That won't work. These teachers were front-line workers before. They can see through this kind of low trick at a glance... Tianxia Guihuo frowned. The other members of the dungeon team also felt a sinking feeling in their hearts.

At this moment, they saw Yuanshi Tianzun pick up the small brown horn and say calmly, "I gave Zhao Chenghuang a spiritual rune manual." Immediately, he coldly threw the brown horn on the table. "Star Explorer, now it's your turn to answer my question."

Star Explorer looked at the unresponsive small horn, first frowned, then suddenly understood. Zhao Chenghuang and Yuanshi Tianzun were trading last night. The content of the transaction was obviously the method of drawing runes in mid-air that Yuanshi Tianzun showed on Chicken Heart Island. For Star Officials, that was an irresistible temptation. He had also been thinking about it for a long time. Star Explorer recalled the events of that day and believed that Zhao Chenghuang seeking a trade was reasonable and logical.

"So that's how it is. I understand. I'll report this to the dean."

"Well done!" Beneath Zhao Chenghuang's cold expression was a surge of surprise. Yuanshi Tianzun's operation was simply divine. He first showed extreme displeasure and anger, and then combined it with the three people's exchange on Chicken Heart Island that day, perfectly resolving the situation. Star Explorer wouldn't be suspicious, because Yuanshi Tianzun did give him a spiritual rune manual, and as someone who was present that day, he would be able to figure it out with a little association.

Tianxia Guihuo and the others looked blank, not understanding what magic Yuanshi Tianzun had used to so easily gain Star Explorer's trust.

"Teacher!" Zhang Yuanqing called out to Star Explorer, who was getting up to leave, and asked, "What are your thoughts on the killer?"

Star Explorer was silent for a few seconds and said in a low voice, "I suspect the killer and the mysterious person who sneaked into Jiaoren Lake on the first night of school are the same person."

Zhang Yuanqing raised an eyebrow: "Why do you say that?"

"Because neither the lie detection device nor the Insight Technique worked, and this ability is very rare. Not everyone can have it," Star Explorer said, stating his reason.

"Very rare, which means it exists, right?" Zhang Yuanqing thought for a moment and said, "Do you know what abilities can bypass lie detection and Insight Technique?"

Star Explorer showed hesitation.

Seeing this, Zhang Yuanqing turned to call the waiter: "Pour a cappuccino for the teacher."

Seeing Yuanshi Tianzun's posture, Star Explorer reluctantly sat down, looked at Zhao Chenghuang, then looked at Yuanshi Tianzun, and lowered his voice: "Didn't I say it on the island that day? Taiyin symbolizes secrecy."

Zhang Yuanqing frowned: "But there are only so many Star Officials on the island, and only Zhao Chenghuang cultivates Taiyin."

Zhao Chenghuang glanced at him and said calmly: "My Taiyin power is not yet complete and cannot block lie detection devices. Sun Miaomiao cultivates the stars, and Yuan Ting doesn't have enough merit to get the cultivation secret methods."

"Then it's not Taiyin," Zhang Yuanqing shook his head.

"You don't understand what I mean..." Star Explorer hesitated again, "The great completion of Taiyin power can not only hide oneself but also bestow it on others. When I was still a frontline worker, I was responsible for arresting a rogue magician. The magician could perform divination, so the elders of the sect bestowed the power of secrecy upon me so that actions related to me could not be divined."

The dungeon team fell into contemplation.

The great completion of Taiyin power can bestow the power of secrecy on others... The Armor Man killed Xia Chaoxue without hesitation for the treasure behind the stone door. This ruthless approach doesn't seem like a normal official Saint, because it will inevitably lead to a split with the official... But someone who isn't an official can't enter Qinfeng Academy. Connections like Hongjige are unique. Someone in the official, but clearly not a true official member... Damn it, Night Rose?! Zhang Yuanqing's mind went into overdrive.

In that instant, he suddenly solved a long-standing doubt - why Night Rose members can always evade the official annual physical examinations. The leader of Night Rose is a Night Wanderer profession, and one of very high status. He (she) bestowed the power of secrecy on important figures in the organization, so the physical examination would definitely not detect it.

Everything makes sense. A Night Rose member has infiltrated these students! No wonder he killed without hesitation. The double agents of Night Rose are like this. Night Rose members are lurking in the official and spirit realm families, and some are in high positions, so it's understandable that they know about the academy's hidden missions. Damn it, why is it so coincidental? Why did they choose this year? I'm so unlucky... No, maybe it's not bad luck. Star Officials can use star gazing to observe the direction of things in the world. If that leader coveted the hidden mission, then it's very likely that he observed the celestial phenomena at night and sensed that the time was ripe. So he ordered a double agent lurking in the official to participate in this training. The Armor Man scouting, applying invisible materials, and monitoring the stone door every night can all be explained. It's Night Rose again. This damn organization has a karmic debt with me... Zhang Yuanqing took a deep breath, looked at Star Explorer, and said, "Teacher, we need to talk. I think I know the hidden identity of the killer."

His first reaction was to tell the dean and cooperate with the school to arrest the Night Rose member hidden in the academy.
