Seeing the growing displeasure on Tian Hu and Yuan Shi Tian Zun's faces, the latter even losing his temper, Sun Miao Miao maintained a serious expression and approached with a composed air: "Let me take a look..." After reviewing the item details, her round face immediately fell. "The door can only be opened once every half hour. To access David's room, we'll have to wait until nightfall." Once H Zhao Cheng Huang and Zhai Cai studied the door lock information, they both became statues—faces rigid, motionless. In the first half-hour, they opened the door to Dong's room. Then, as night fell, the giant red chicken, Red Chicken Brother, perished and was eliminated. In the second half-hour, they opened the door to the single-legacy knight's room. To reach David's room, they would have to wait until the third half-hour—but before then, there would be another nightfall. And whenever night fell, someone would die, with the clues from that room permanently sealed. After a moment of silence, Zhao Cheng Huang said, with evident frustration, "I suddenly realize Red Chicken Brother was absolutely right!" Would it have been better to choose the battle quest back then?" The next night, no matter who died, the team would lose a crucial piece of evidence, making the investigation increasingly difficult. Zhai Cai sighed, then smiled. "No, choosing the battle quest is better—there will surely be casualties. Believe me, with an eight-level difficulty, I and Juming can guarantee we make it through, but we cannot guarantee the team will come out unscathed. Choosing the mystery case may result in total loss, but it's the only chance of reaching the end without any casualties. "Our country has a saying: 'Give it a try, and even a bicycle becomes a motorbike.'" Sun Miao Miao corrected: "That's not an old saying—it's a modern internet phrase." "Oh, fine, fine!" Zhai Cai blushed slightly, waved her hand, and then gave a serious analysis: "In fact, the killer is already narrowed down to Dong the Magician, Daniel, and the Werewolf. As for the Werewolf, he is either David the Family Teacher or Lorne the Gardener. No matter who dies tonight, we will be able to identify the Werewolf's identity." "At that time, as long as we could identify one killer from among the three roommates, we'd be able to solve the castle mystery and leave the scroll behind." Zhang Yuanqing felt a spark of inspiration. Zhai Cai's tone and expression conveyed ease and confidence, as if the case was already settled—almost with a quiet sense of anticipation, as though he were poised to take home the MVP title. What gave him this courage and confidence? It couldn't have been merely intelligence; it was likely his unique character skill! He didn't know what specific skill he had acquired, and he was sorry he couldn't ask—this thought drifted through Zhang Yuanqing's mind. He glanced at Shan Chuan, the knight, and remarked, "Don't get too excited yet—perhaps it'll be you who dies tonight!" If the witch claims him, no matter how powerful his skills, they'll be useless. Zhai Cai's face fell, and he fell into thoughtful reflection. About one hour before nightfall, the group discussed intently, their nerves tense. Tian Xia Gui Huo, leaning against the wall, said: "Dong's motive for the murder is clear, and there's solid physical evidence. In comparison, Daniel the exorcist and the werewolf have lighter suspicions. Daniel has no clear motive for the killing, and as for the werewolf, we learned about his involvement at the scene." At the scene, it was reported that when the werewolf consumed the castle's owner, there was no resistance or struggle—the owner was completely unable to fight back. It remains unclear whether the owner was already dead or merely unconscious at that moment. The three fatal wounds must have occurred in a specific sequence—some before others. Zhao Chenghuang and Sun Miao Miao actively participated in the discussion, while Zhang Yuanqing took the opportunity to say, "I need a quiet place to think about some matters. I'll go back to my room now." The three saints were somewhat puzzled but didn't press further, allowing him to go. Only Zhai Cai seemed to be reflecting. Entering Dong Fashi's room, Zhang Yuanqing opened his inventory, retrieved a black wooden box, then took out an ice pen from within the box. Following the system's prompts, he paid all the required points and activated his扶乩skill. He could no longer hide this skill anymore—he was afraid that the witch might kill him in the night. After paying for the skill, the intricately carved ice pen automatically detached from his hand and hovered above the desk, beginning to melt and leaving small droplets on the surface. Zhang Yuanqing regrasped the pen and softly murmured: "The killer of Yá·Lánshēng, the killer of Yá·Lánshēng..." As he repeated these words, a powerful force flowed into the pen, and then, without conscious effort, his hand slowly moved beneath the influence of the pen, writing the letter 'd' on the desk. Immediately afterward, the force attached to the pen vanished, and the pen fully melted, submerging the letter 'd'. “d……” Zhang Yuanqing furrowed his brows, trying to interpret the results of the spirit writing. After a few seconds, he understood the meaning of the letter “d.” Among the six characters, those with the name beginning with the letter “d” were Dong the法师, Daniel, and David—corresponding to himself, Dan Xuan the Knight, and Tianxia Guihuo. “So Tianxia Guihuo is the werewolf? Yes, my earlier deduction was correct—the murderer is indeed among these three.” Zhang Yuanqing wiped the water stains on the table and left the room. Although the spirit writing did not provide a precise answer, it confirmed their reasoning: the murderer was among these three, and they could now be confident there would be no further complications. The three saints who had returned from the afterlife continued discussing the case. Zhai Cai stood with his hands on his chest, leaning against the wall, listening attentively without speaking. Upon seeing Zhang Yuanqing return, he smiled and spoke proactively, “Have you found any new clues?” Zhang Yuanqing nodded. “The murderer must be among Dong the法师, Daniel, and David.” "The whole world is still skeptical about my claim," said Tian Xiang Gui. "How do you know I'm actually a werewolf?" "Intuition!" Zhang Yuanqing replied. "I believe in your intuition!" Zhai Cai nodded firmly. Wait—didn't I die? Zhang Yuanqing was astonished and immediately turned to his companions. One after another, the faces of the single-charge knight, Tianxia Guihuo, and Zhao Chenguang appeared in his sight, yet there was no trace of Sun Miaomiao. But there was no body of Sun Miaomiao on the corridor—only a charred, oil-smeared human silhouette. Sun Miaomiao had vanished! "Where is Miaomiao?" Zhao Chenguang stared at the human silhouette on the ground, his voice slightly uncertain. Zhai Cai gasped, approaching the silhouette and said, "There she is—yet why such a manner of death? The witch always kills each night in a different way." Even though there was no light in the night, Miaomiao had been burned down to ash, leaving not even a trace of bone. "It might be a matter of identity. Sun Miaomiao is from the Lans family, and the witch has a long-standing grudge against them. Perhaps that's why her death is so unusual!" Zhang Yuanqing spoke with a tone of relief. She hadn't died—thank goodness! "As long as David is alive, that's all that matters." "Zhai Cai smiled and said, 'Open the door and take a look at what clues are inside the room.' There's no need to dwell on Sun Miao Miao's cause of death, since neither Zhai Cai's nor Yuan Shi's theories can currently be verified—at least not yet. Tian Xia Gui Hu turned his gaze and walked to the door, spending ten points to open it. 'Creak~' He pushed open the wooden door, inviting his teammates inside. The layout and furnishings were just as before, with a simple, medieval charm, though this room featured a much greater number of precious vellum scrolls—far surpassing the previous two rooms. Vellum was difficult and costly to produce, traditionally reserved for noble families. In this room, there were no fewer than a dozen scrolls. Zhai Cai approached the desk and began reading the scrolls. Zhang Yuanqing went to the wardrobe, while Tian Xia Gui Hu and Zhao Chenguang searched the bed and beneath it. Soon, Zhang Yuanqing found a small ceramic jar from the wardrobe first. Inside, the liquid was dark and when he sniffed it, he detected a very faint blood scent. "I've made a discovery!" he said, holding the jar up. Zhai Cai, Tian Xia Gui Huo, and Zhao Chenghuang gathered around immediately, passing the jar among them, each unsure of what the dark liquid was. Zhao Chenghuang thought for a moment, then said, "Jumu, try it!" Zhang Yuanqing paused thoughtfully, considering it a sound strategy—when the nature of the liquid was uncertain, tasting was the most reliable way to assess it. With the Night-Wanderer's strong vitality, self-healing abilities, and healing items and life-source liquid stored in his inventory, he could confidently sample the liquid during the day when the castle wasn't sealed. Thus, under the three of their curious gazes, Zhang Yuanqing lifted the jar and took a small sip. "What does it taste like?" they all asked promptly. Zhang Yuanqing chewed his lips. "It's blood, but there's an indescribable sweetness to it—poisonous, certainly. It will kill ordinary people, but it poses no threat to me." "So it's just a poison, then," said Zhai Cai, nodding. The three of them went through it together, and what they found was the history of the Lans family—clearly stating that the Lans family had been a lineage of witches, who suddenly declined a century ago, with all the family's witches perishing and their black magic lost to history. The parchment was dotted with holes from insect damage, suggesting it was quite old. "He had just finished speaking when Zhang Yuanqing immediately countered: 'The murderer must be one of David, Dong the Master of Divination, or Daniel—absolutely not Luin, the role of Zhao the City God. How could David not be the wolf? Something must have gone wrong.' Tianxia Guihuo and Zhao the City God didn't understand why he was so certain about David being the killer. The Fire Master furrowed his brows, 'What's your reasoning?' 'I have my own method,' Zhang Yuanqing implied subtly. 'You just need to understand it,' he added. The Fire Master's brow furrowed even more tightly, 'What are you talking about? I don't understand!' At this, the knight standing beside them also paused, 'You don't understand?' Tianxia Guihuo looked puzzled and amused, 'What are you two talking about!' Zhang Yuanqing and Zhai Cai exchanged a glance, each seeing a question mark in the other's eyes.
