In that sea of ​​overlapping memories, Yin Xiu saw the Black Emperor's Son that he was looking for through Sima He's was truly a beautiful iceberg beauty. Sima He stared at her closely, wishing he could eat her alive. However, other masters of the palace were also keeping an eye on her, telling him not to act rashly, so he couldn't bear it and ran here to relive the past. "The Forbidden City is so filthy." Yin Xiu shook his head. "if not?" Ren Qi glanced at him and said, "All the masters in the palace are like this, not to mention those old monsters who have been in the palace for a long time." He had no intention of continuing the conversation with Yin Xiu, so he just asked, "How is it, have you found the whereabouts of the Black Emperor?" "Have." Yin Xiu let out a long sigh, "She is at the Imperial Astronomical Observatory." "Qin Tian Jian?" Ren Qi also frowned, "That's a troublesome place. When I was a master in the palace, I never went there. It was because my position was not high enough and because masters of the palace were not allowed to go there."

"What kind of person is the Grand Master Dongfang Weilai?" Yin Xiu asked him. "You should ask Ma Xiaoyu about this." Ren Qi smiled. "After all, she was the one who had a conversation with Dongfang Weilai. I just looked at him from a distance and felt that he didn't look like a national teacher. Instead, he looked like a young man from a village deep in the mountains." "Really? Then let's go back first." Yin Xiu had heard her mention Oriental Future last time, but at that time they had too many things to do and had no time to ask more questions. This time, he had to ask clearly, after all, the Imperial Observatory was a place that even Ren Qi could not get involved in. Yin Xiu glanced at the corpse on the ground and said, "I heard that there is a medicine in the palace that can turn corpses into blood?" "No need to bother." Ren Qi carried Sima He's body, walked into the house, and stuffed him under the bed, where Sima He had been lying before. But now, he was lying there forever. "It's going to stink in this weather, right?" Yin Xiu frowned. "It's ok." Ren Qi patted his sleeves and said, "The smell of this opium will last for a few days. When he finds the gift under the bed, it will be a pleasant surprise." Yin Xiu felt a chill, "Where did you learn this evil taste?" Ren Qi looked at him, "What do you think?" "Forget it, just pretend I didn't ask." …… When Yin Xiu and Ren Qi returned to the Ren family mansion, there were a few unfamiliar faces there. Liu Banxian introduced them one by one, "These people are all masters of Feng Shui. They are good at finding dragon points and arranging Feng Shui formations."

After Yin Xiu nodded to several people after his introduction, he asked in a low voice: "Where is Xiaoyu?" "Miss Ma? She should be in the room." "Okay, I'll leave this to you." After saying this, Yin Xiu walked towards the yard. Liu Banxian shook his head and said, "Young people are always hot-tempered. Didn't he just get up not long ago?" Yin Xiu didn't hear this and just pushed the door open. Ma Xiaoyu was sorting out the magic weapons at this time. She exposed her thighs and tied several magic weapons to the belt. "You didn't even knock on the door." She said coquettishly. However, Yin Xiu just walked straight over, picked her up, and went behind the curtain. After a long while, when Ma Xiaoyu's breathing became long and her expression became lazy, Yin Xiucai patted her and asked her to move her head closer. "Why are you in such a hurry? Let me rest for a while." She spoke weakly. Yin Xiu smiled, ruffled her hair, and asked softly, "Dongfang Future, how is it?" "You're better than him." "Well!?" Yin Xiu was surprised, and when he looked over he found that Ma Xiaoyu had a smirk on her face. Yin Xiu pinched her face and asked, "Who taught you to say that?" "So you're allowed to say those weird things?" Ma Xiaoyu leaned in, almost wanting to melt her body into him. "And I do think that even though he is the national teacher, known as the best Taoist in the world, you, an unordained Taoist, are better and stronger than anyone else in my heart." "Stronger than the Heavenly Master?" Ma Xiaoyu glanced at him and said, "Aren't you already above the Heavenly Master?" "But sometimes the Master is on top of me, isn't he?" Ma Xiaoyu finally couldn't convince him and could only lower her head with a red face. Yin Xiu touched her forehead lightly and finally got to the point: "The Black Emperor is in the Imperial Observatory. We have to go there." Ma Xiaoyu nodded. "We found out her location so quickly. This is good news." "It is indeed good news, but the bad news is that we currently know nothing about the Imperial Observatory." Although Yin Xiu had glimpsed some of the topographical structures of the Imperial Observatory from Sima He's memory, this was not enough. Because Sima He only operated within his limited scope, he had no chance to explore other parts of the Imperial Observatory.

Ma Xiaoyu also understood what Yin Xiu meant. "The Imperial Observatory is the place that governs the mystical sects of the world. Its defense is probably no less relaxed than that of the Forbidden Palace." "Yes, so we'd better get the blueprints of that place and know its layout better." “This is difficult to do…” Ma Xiaoyu pursed her lips and said, "It would be very risky for you to go into the palace again and find someone who is familiar with the layout of the Imperial Observatory. After all, the masters of the palace may have already made many arrangements there." Ma Xiaoyu frowned and suddenly thought of something, "How about we go to the ghost market?" "Ghost market?" Yin Xiu put his hand down and thought: "How can there be such a thing in the ghost market?" "It's hard to say, um..." Ma Xiaoyu's voice trembled a little. "I think there should be, well, everything there." "Even a topographical map of the palace?" Yin Xiu ignored Ma Xiaoyu's protests and changed the shape of his hands, "These people are selling everything?" "I heard from my aunt, um, my aunt said that after the craftsmen in the palace finished their work, they would always leave something for themselves, either by carving words on a brick or drawing a sketch." "It sounds like it happened a long time ago." Yin Xiu gently pushed away Ma Xiaoyu's hand that was just a formality. "Even if the overall layout hasn't changed, the details may be completely different. After all, it may be a blueprint from the previous Ming Dynasty." "Details, um, I heard that the Forbidden Palace was renovated ten years ago, so there will probably be craftsmen..." Ma Xiaoyu couldn't say anything more and looked at Yin Xiu with her watery eyes. Yin Xiu also looked at her, "The ghost market is only open at night, right?" Ma Xiaoyu just nodded, her eyes flickering. "Then we still have a lot of time." …… The ghost market is located in the deserted West City. Because the water here is bitter and salty, those who can afford it have moved to other urban areas. Only a few scattered households are left, and it is unclear whether they are human or ghost. This place has become a den of ghosts. Even though Yujing had been turned upside down and in chaos during the day, it seemed that all this had nothing to do with this den of evil. At night, when the ghost market in Yujing opens, all the evil spirits that are not tolerated during the day gather here. Among these people, some are notorious bandits on the wanted list, some are evil cultivators who are not tolerated by upright cultivators, and some are truly ghosts wandering around in the world. The purpose of their coming here is either to sell stolen goods or to trade for something that is enough to keep themselves alive. Sometimes it is a weapon, sometimes it is just a message. Ma Xiaoyu and Yin Xiu wrapped themselves in cloaks to hide their figures and faces, and they were dressed exactly the same as the people here. Speaking of which, the Ghost Market is a place that Ma Xiaoyu often visits.

She searches for rare spells, instruments and tools here. The first rule when entering the ghost market is not to open your mouth. It is said that this is because people are afraid that someone will open their mouth and spit out human breath, which would alarm and attract those wandering ghosts. Therefore, Yin Xiu and Ma Xiaoyu both held a copper coin in their mouths, pressing the root of their tongues. The two of them first took a casual stroll in the ghost market. There is really everything for sale here, including talismans, magic tools, corpses, and even freshly unearthed coffins that smell like earth. Some of the coffins were covered with talismans, and some were tied with iron chains as thick as fingers, which gave people an ominous feeling at first glance. Yin Xiu and Ma Xiaoyu stopped in front of a stall. The owner of the stall was a pale man whose age could not be determined. Under the light of a candle that glowed green, all Yin Xiu could sense from him was weakness and illness. The stall owner was selling all kinds of picture albums, with all kinds of graphics drawn on the yellowed paper. Without saying hello to him, Yin Xiu squatted there and started searching. However, the drawings on it were all topographic maps of a certain mountain or a Taoist temple, with occasional drawings of a mansion or a palace, but those were not what Yin Xiu was looking for. Yin Xiu knew the general appearance of the Imperial Observatory, so what he was looking for was a detailed topographic map that would mark every road and every entrance. After he searched everywhere without success, Yin Xiu and Ma Xiaoyu immediately planned to leave. Just then, the stall owner spoke. "My man, what you are looking for is hard to find." His words undoubtedly broke the unspoken rules of the Ghost Market, but in fact no one wrote this rule down or signed it. Therefore, at most he offended others and could not be called a destroyer. Yin Xiu simply spat out the copper coin from his mouth. The stall owner blinked when he saw it. "Oh, the Five Emperors' Coins, so they are the two Taoist masters." He said this but didn't actually do anything. It sounded more like a tease than a greeting. Yin Xiu got straight to the point, "Can you find all the blueprints?" The stall owner didn't reply, but just held out his hand. Yin Xiu was puzzled and glanced at Ma Xiaoyu. Ma Xiaoyu didn't explain, but took out a gold bean from his pocket and put it in the stall owner's hand. The stall owner then closed his hands and started talking. "It all depends on what drawings you want. Foreign mechanical design drawings, Qimen Dunjia spells, Feng Shui points of a certain place, as long as you want it, I can find it." Seeing that he was so straightforward, Yin Xiu didn't waste any more words.

"I want the blueprints of the Imperial Astronomical Observatory." The stall owner was stunned for a moment. This time he did not open his palm, but shook his head. In this way, Yin Xiu had no choice but to stand up with Ma Xiaoyu. "Wait, man." The stall owner called him back, "I know where you can get it, but you have to have the ability." "where?" The stall owner didn't answer, but just raised five fingers. So Ma Xiaoyu took out five golden beans. …… When they followed the stall owner's instructions and came to the dilapidated city wall of the east gate, just as he said, the sound of knocking on the door floated again and again in the empty street. The East Gate is an abandoned area. It is said that the Ming Dynasty did build a city area here, but it was completely destroyed in the war. Therefore, only this section of the city wall and the half-missing city gate are left. Listening to the banging of doors and the sobbing and crying, Yin Xiu and Ma Xiaoyu wiped their eyes with pomelo leaves. I saw a "person" wearing iron armor and an old helmet next to the dilapidated city gate. He kept banging on the city gate with his hands and crying, as if his way was blocked by the city gate. Yin Xiu and Ma Xiaoyu looked at each other and took out a piece of talisman paper from their pockets. As he threw the talisman paper over, the wall that seemed like air and was originally near the city gate disappeared. Men in armor walked into the city, and every step was accompanied by the sound of rotten armor rubbing against each other, which was harsh and creepy. He couldn't see Yin Xiu and the others, he just kept walking forward, his body passing through big trees, walls, and collapsed walls. Yin Xiu and the others followed behind him, restraining their breath. They walked for a while until they came to another house. This is a house that looks warm and exquisite compared to other places. At the door stands a tree that looks very old. Half of the trunk is crooked, and branches and leaves hang down from the top to the bricks and tiles. Yin Xiu and the others followed the armored man in and saw that there was actually a "person" sitting in the yard. She was an old lady wearing simple clothes and a pair of embroidered shoes. She was originally mending something with needle and thread. When she saw the iron man coming in, she seemed to tremble and couldn't believe it. The armored man also stood there in a daze. After a while, the two "people" finally approached each other and hugged each other tightly. The plaintive wailing was again in the air, but this time it didn't sound creepy. Yin Xiu walked over quietly, picked up the drawing that the old woman had dropped on the ground, opened it and saw that it was the scroll of the Imperial Observatory. Although it seemed to be quite old, they couldn't find any newer ones.

Ma Xiaoyu took out a piece of talisman paper, recited a spell silently in his mind, and then threw the talisman paper out. The two figures were enveloped by the rosy glow and disappeared together in the light. As soon as they disappeared, the houses collapsed, the old trees died, and everything returned to its original state. "Taiyi Rescue Heavenly Lord..." Ma Xiaoyu said softly, her eyes a little red. "Tell me, if one day we both...will you be like him, thinking about the way home every night for so many years, and come back to find me?" Yin Xiu hugged her gently and said, "I promise you, even if I have to die, I will not die outside. I will come back with a breath left." "Don't talk nonsense." Ma Xiaoyu stopped him, buried her head in his chest, and said seriously: "But I will wait for you to come back, no matter how long it takes." (End of this chapter)
