I can rewind time to prevent death

According to Xia Ruolan's description of her dreams, in the first dream, she was directly "frightened awake" and then proceeded to the next dream. In the second dream, however, she was continuously stung by the sharp thorns of a plant, which jolted her awake with a shock of pain, leading her into the third dream. In the third dream, she was tripped by dumbbells, which eventually brought Xia Ruolan to full consciousness. Therefore, Yan Junze deduced that the arrangement of certain items in the dream was directly projected from reality. The plants in Xia Ruolan's home were originally placed under the window sill, just like in the dream, and that's why she was pricked. The same logic applied to the dumbbell. That's why he had preemptively placed Burst Nails in certain spots around the house to find these sharp objects at critical moments in the dream, to prick himself and wake up quickly. Now, the main concern was which layer of the dream the woman in the black dress appeared in and whether the other people appearing in the dream were figments of the imagination or not. Yan Junze believed that as long as the Black Dress Woman existed in that layer of the dream, Mission Perception would definitely detect some mission information and wouldn't be empty. The Spacetime Atlas in his mind existed beyond the boundaries of space and time, and the current dreamscape could likewise be considered a unique product of a special space and time, belonging to some unknown dimension. This could be seen from the fact that if someone died in their dream, they would also die in reality. Moreover, in his previous life in a laboratory in Hua Country, Yan Junze, although only an assistant, had participated in the verification assistance for spacetime research. However, as an assistant, his understanding of the deeper principles was not thorough, but the probability that the Spacetime Atlas could still be used in the dreamscape was quite high. Just now, in the third layer of the dream, Yan Junze became aware that he was dreaming and initiated Mission Perception, which was quick but didn't provide any mission information. If the Black Dress Woman were there, even without initiating Mission Perception, the task information regarding strangeness would most likely pop up on its own. He chose to initiate perception just in case, to avoid the situation that had occurred with the Tricky Silk branch mission last time. In front of Huang Chen, the initiated Mission Perception yielded no feedback, indicating that this "Huang Chen" was not the Black Dress Woman. There was another purpose for initiating Mission Perception in this room. Because for a mission to pop up on its own, the target strangeness had to be within a certain distance. If too far from the target, the mission information wouldn't jump out automatically. Initiating Mission Perception resolved this issue perfectly; even if one of those people sleeping in the hall were the projected incarnation of the Black Dress Woman, Mission Perception would still be able to detect and display the mission information at this distance. Unfortunately, there was still no information. This meant that the Black Dress Woman was also absent from this layer of the dreamscape. Without the Black Dress Woman, the most critical character was missing, making it impossible to fully solve the problem. At that moment, Huang Chen was approaching step by step, with a dark expression and a hint of a strange smile on his lips, reaching out towards Yan Junze's neck. Yan Junze once again pressed his finger against the sharp thorns of a Burst Nail. A burst of pain struck him, and his head immediately felt dizzy, but he did not "wake up" immediately like before. He pressed another Burst Nail with the thumb of his other hand, this time with more force. The pain of the thorn piercing the skin and sinking into the flesh spread throughout his body and due to the severe pain, his heart seemed to clench. His head felt even heavier, as if he couldn't see the surroundings clearly, everything before his eyes blurred. Huang Chen closed in quickly, his outstretched hand almost touching Yan Junze's neck. All the scenery vanished, leaving only a vast whiteness before his eyes. The next second, Yan Junze opened his eyes and found himself still lying on the pieced-together chairs, undisturbed under the blanket. He slightly raised his head to see Xiang Er standing beside him, facing him, not looking out the window at the night view. Seeing him awake, Xiang Er said in surprise, "You're awake? It's only... huh, not even three in the morning yet." With the sensation of being pricked still lingering, Yan Junze looked at the skin of the finger that had been pierced. Finding it intact, the pain seemed like an illusion, a very real illusion. He sat up, turned to look towards the window, which was closed just as it had been when he had fallen asleep. "I've been asleep the whole time?" Yan Junze asked. "Yes," Xiang Er nodded. "Did I not get up? Or talk in my sleep?" "No, I've been watching you. You were sleeping soundly." Yan Junze raised his right hand to his forehead, his head still feeling heavy, as if he wanted to sleep but was unable to due to a shock. Now it seemed his dreams were not quite like Xia Ruolan's; they only manifested two layers and did not result in a dream within a dream within a dream. After a moment, he spoke, "While I was asleep, did anyone come up from downstairs?" "No, the people downstairs were moving around all the time," Xiang Er was always attentive to the surrounding sounds, "I could sometimes hear them talking, but no one came up." "I can't seem to sleep right now. I'll go down and have a look. I'll be right back." Yan Junze nodded, touched the Burst Nail in his pocket, and suddenly paused. "Looking for this?" Xiang Er opened her hand, showing two Burst Nails lying quietly in the palm of her hand, "They fell out of your pocket after you fell asleep."
