"You're constipated!"

Zhang Yuanqing flicked her forehead, and before Sun Miaomiao could angrily retaliate, he pressed his earphone:

"I think I know what's going on."

The underground palace team's hearts lifted, but they didn't show it on their faces, either pretending to drink coffee or pretending to admire the scenery, attentively waiting for Yuanshi Tianzun's explanation.

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

Zhang Yuanqing explained his guess, concealing his headache and only saying that he had a prop to activate memories. So that's it! The underground palace team suddenly understood. Tianxia Guihuo felt a slight relief. He was most afraid that the Armored Man had monitoring methods that were imperceptible and incomprehensible. If that were the case, their side would be very passive. "Based on Xia Chaoxue's death, we can deduce that the Armored Man infiltrated Mermaid Lake to check for traces in the late night. During the day, he needs to attend classes, and there are many people around. The same is true at night. Only the late night when everyone is asleep is suitable for sneaking into the lake. If I were him, I would also choose the late night when I wouldn't be discovered." Tianxia Guihuo lowered his head and drank coffee. Yuanshi entered the underground palace twice, once in the morning and once at night, perfectly avoiding detection. Sun Miaomiao pretended to stare at the ceiling, "In this way, the Armored Man is unlikely to be a Star Official. Starry Sky Explorer and Yuan Ting are not the Armored Man." Star Officials have Spirit Servants and Yin Corpses, so they don't need to sneak into the lake themselves and can monitor the situation of the stone door at any time. Yuanshi Tianzun is an example. Xiahou Aotian said, "Are there any ideas for the remaining three questions? If we solve these three questions, we will understand the context of the matter. I still feel something is wrong..." He thought for a moment and spoke with his thoughts: "Imagine, if I were the Armored Man, I would choose to secretly search, lock the target, and then take action. Instead of killing someone and making it known to everyone, that's a lose-lose situation." As Zhang Yuanqing was about to speak, Hongjige slammed the table angrily, "Enough! Your depression is unbearable for me!"

Library, conference room. The gray-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, "There are 11 people in the entire academy who can corroborate each other's whereabouts in the late night. Among them, 9 were eating grilled skewers and drinking porridge in the cafeteria, organized by Hongjige. They ate and drank until 1:30 AM. The other two are Yuanshi Tianzun and Zhao Chenghuang. "The others were all in their dormitory rooms and rested early." Huo Mo Luo Lesheng said in a muffled voice. "Can these people be ruled out as suspects?" The old dean shook his head: "No, these people are the ones we can investigate. Those who were alone in their rooms are the ones who are impossible to investigate. Because no one can verify whether they are telling the truth." After a pause, he raised his teacup and took a sip, and said: "Next, we need to verify two things. The first thing is, according to the records of the students in the cafeteria, Zhu Mingxu left halfway and returned after more than ten minutes. "The second thing is, Yuanshi Tianzun and Zhao Chenghuang stayed together all night? According to my usual observation, Hongjige's treat has never been missed by Yuanshi Tianzun. Starry Sky, take the lie detection prop and ask them." Starry Sky Explorer nodded and left the conference room. The old dean looked at the remaining teachers and said, "Next, let's think about the Armored Man's motive for killing."

Everyone was startled by Hongjige and stared blankly at him, not knowing what this vulgar Fire Demon was going crazy about. Hongjige cursed, "I can't stand it anymore! You haven't said a word since you entered the coffee shop. "Isn't it just one student who died? What's there to be depressed about? We've only known each other for a few days. Of course, I'm also very unhappy that someone died, but life must go on, right? I suggest we go to the cafeteria for lunch and drink a bowl of fresh and delicious congee. You'll feel better after drinking it." He thought we were sad? Everyone stared blankly at Hongjige. "Why are you looking at me like that? Am I wrong?" Hongjige glared. "Ah, yes, yes, you're right." Everyone nodded in unison. "I admire Hongjige's simplicity..." Zhang Yuanqing laughed, "We're just wondering who the murderer is. After all, we have to stay here for three days. The sooner we find the murderer, the more at ease everyone will be." "That's also true." Hongjige nodded: "Then have you figured out who the murderer is?" "Anyway, it's not you." Sun Miaomiao snorted twice. "Little girl, I think you want to fight. I'm a firm supporter of gender equality. I never hesitate to hit women, even if you're in an ambiguous relationship with Yuanshi Tianzun." Hongjige understood her mockery, just like the dean's mockery back then. "Who is in an ambiguous relationship with Yuanshi Tianzun?" Sun Miaomiao reacted strongly.

At this moment, Yuanshi Tianzun's voice came through the earphones. Xiahou Aotian's doubts are related to why Xia Chaoxue died. There may be another reason why the murderer killed Xia Chaoxue. "But in any case, the fact that the stone door has been opened is now known. We must find the murderer and kill him (or her) so that he (or she) cannot leak this matter." Tianxia Guihuo narrowed his eyes, concealing murderous intent: "We must find him and kill him before the academy teachers find him." 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 Armored Man won't easily reveal this matter, because he's also after the treasure. Besides..." Zhang Yuanqing's words were interrupted again, but this time it wasn't Hongjige, but Starry Sky Explorer. This Star Official, with ordinary features but a ethereal and noble temperament, entered the coffee shop. "Everyone looked over. I asked around and heard the students say you were in the coffee shop." Starry Sky Explorer walked to the table, sat down gracefully, and looked at Yuanshi Tianzun and Zhao Chenghuang, "The dean asked me to ask you what you were doing last night?" Fortunately, Starry Sky Explorer wasn't a scout, otherwise he would have been able to see the underground palace team's moment of gravity. "Damn, will this ever end? Keeping this lie detection prop is simply a disaster..." Zhang Yuanqing's heart tightened. He looked at Zhao Chenghuang, whose expression became even colder. Tianxia Guihuo, Xiahou... Aotian, and Sun Miaomiao looked over silently. Beneath their calm exterior, their brains were working frantically. They avoided the lie detection prop in the morning thanks to Zhao Chenghuang's wit, which was just a coincidence. This time, they were directly confronted face-to-face with a one-on-one question. If the same operation happened again, even a fool would be able to see the problem... Use ambiguous rhetoric to solve it? For example, Zhao Chenghuang and I were doing something secret together? No, this kind of rhetoric can't fool anyone. You can't treat people like fools. If they ask what it is specifically, I won't be able to answer. Zhang Yuanqing's thoughts were boiling, but his surface was extremely calm. He glanced at the brown horn placed on the table and said in a deep voice, "Starry Sky Teacher, before I answer you, you need to answer me a question first." Starry Sky Explorer stared deeply, "Speak. Why does the dean care so much about what the students did last night?" "Since the lie detection prop can't detect the result, we can only try to understand the information as much as possible, and maybe we can get a clue." Starry Sky Explorer said. "Then I think your question shouldn't be what you did last night, but some more precise questions, such as: What is our relationship with Xia Chaoxue? Did we have any feelings for her? Did we have any private contact with her?" Zhang Yuanqing smiled, "Aren't these more targeted?" He was stalling for time while entering Yin Yaojunzhu's body and activating White Face. Because of the sudden incident in the morning, he believed that there would definitely be similar encounters in the future. Therefore, he obtained Yin Yaojunzhu's consent that he could enter and leave her body at will for the next three days. "Good idea." Starry Sky Explorer nodded, "Then you answer these questions." Zhang Yuanqing smiled, but there was no trace of a smile in his eyes. "Your attitude makes me very unhappy. I'm not a suspect. Pay attention to your tone. If this wasn't the academy, I would have pinned you to the ground and beaten you, even if you're Level 5." Starry Sky Explorer said coldly, "Please hold the prop and answer my questions." Yuanshi Tianzun is planning to use an emotional outburst as a reason to get away with it and refuse this lie detection? This won't work. These teachers were front-line workers before. They can see through this kind of inferior trick at a glance... Tianxia Guihuo frowned. The other members of the underground palace team also felt a sinking in their hearts.

At this moment, they saw Yuanshi Tianzun pick up the brown horn and said lightly, "I gave Zhao Chenghuang a Spirit Talisman Secret Book." Immediately, he coldly threw the brown horn on the table, "Starry Sky Teacher, now it's your turn to answer my question." Starry Sky Explorer looked at the unresponsive horn, first frowned, and then suddenly understood. Zhao Chenghuang and Yuanshi Tianzun were trading last night, and the content of the transaction was obviously the Lingkong Drawing Talisman technique that Yuanshi Tianzun showed on Chicken Heart Island that day. For Star Officials, that was indeed an irresistible temptation, and he had been thinking about it for a long time. Starry Sky Explorer recalled what happened that day and believed that Zhao Chenghuang seeking a transaction was a reasonable and logical thing. "So that's it, I understand. I will report this to the dean." "Well done!" Beneath Zhao Chenghuang's cold expression was a surge of surprise. Yuanshi Tianzun's operation was simply a stroke of genius. He first showed extreme displeasure and anger, and then combined it with the three people's exchange on Chicken Heart Island that day to perfectly resolve the situation. Starry Sky Explorer wouldn't suspect anything because Yuanshi Tianzun did give him a Spirit Talisman Secret Book, and as a person who was present that day, he could understand it as long as he thought about it a little. Tianxia Guihuo and the others were confused and didn't understand what magic Yuanshi Tianzun had used to gain Starry Sky Explorer's trust so easily? "Teacher!" Zhang Yuanqing called out to Starry Sky Explorer who was about to leave, and asked, "What do you think of the murderer?" Starry Sky Explorer was silent for a few seconds and said in a low voice: "I suspect that the murderer and the mysterious person who infiltrated Mermaid Lake on the first night of school are the same person." Zhang Yuanqing raised his eyebrows: "Why do you say that?" "Because the lie detection prop and Insight Technique were ineffective, and this kind of ability is very rare. It is impossible for everyone to have it." Starry Sky Explorer said his reason. "Very rare, that is to say, it exists, right?" Zhang Yuanqing thought for a moment and said: "Do you know what ability can hide from lie detection and Insight Technique?" Starry Sky Explorer hesitated. Seeing this, Zhang Yuanqing turned his head and called the waiter: "Pour the teacher a cup of cappuccino." Seeing Yuanshi Tianzun's posture, Starry Sky Explorer reluctantly sat down, glanced at Zhao Chenghuang, then glanced at Yuanshi Tianzun, and lowered his voice: "Didn't I say that on the island that day, Taiyin symbolizes concealment." Zhang Yuanqing frowned: "But there are only so many Star Officials in the island, and Zhao Chenghuang is the only one who mainly cultivates Taiyin." Zhao Chenghuang glanced at him and said lightly: "My Taiyin power is not yet perfect and cannot shield the lie detection prop. Sun Miaomiao mainly cultivates Star Power, and Yuan Ting's merits are not enough and hasn't obtained the cultivation secret method." "Then it's not Taiyin." Zhang Yuanqing shook his head. "You don't understand what I mean..." Starry Sky Explorer hesitated again, "The perfected Taiyin power can not only conceal oneself but also grant it to others. When I was still a front-line worker, I was responsible for capturing a rogue Fangshi. The Fangshi could divine, so the elder of the sect granted me the power of concealment, so that actions related to me could not be divined."

The underground palace team fell into contemplation. The perfected Taiyin power can grant others the power of concealment... The Armored Man killed Xia Chaoxue without hesitation for the things behind the stone door. This ruthless method doesn't seem like a normal official saint, because this will inevitably break with the official... But if they aren't an official, it is impossible to enter Qinfeng Academy. Hongjige is a unique case as someone with connections... Damn it, Dark Night Rose?! A storm of ideas arose in Zhang Yuanqing's mind. At this moment, he suddenly solved a long-standing question—why can members of Dark Night Rose always escape the official's annual general physical examination. The leader of Dark Night Rose is a Night Wanderer, and a high-ranking one at that. He (or she) granted the important figures in the organization the power of concealment, and the general physical examination definitely wouldn't be able to find out. Everything makes sense. Damn it, a member of Dark Night Rose has sneaked into this batch of students! No wonder he kills people without hesitation. The double agents of Dark Night Rose are this kind of style. Dark Night Rose members are lurking in the official and Spirit Realm families, and there are many who hold high positions. It is understandable that they know the academy's hidden mission. Damn it, why is it so coincidental that they chose this year? I'm so unlucky... No, maybe it's not unlucky. Star Officials can use Star Observation to view the trends of the world. If that leader is eyeing the hidden mission, then it is very likely that they observed the heavens at night and sensed that the time was ripe. So, they ordered the double agent lurking in the official to participate in this training. The Armored Man scouting, applying invisible materials, and monitoring the stone door every night can all be explained. It's Dark Night Rose again. This damn organization has a karmic debt with me... Zhang Yuanqing took a deep breath, looked at Starry Sky Explorer, and said: "Teacher, we need to talk. I think I have guessed the hidden identity of the murderer." His first reaction was to tell the dean about this matter and cooperate with the school to arrest the Dark Night Rose lurking in the academy.
