I opened the door, "If you really want to be a hooligan, just come in, what are you shouting?" ”

She smiled mischievously, "Isn't this a relief for you, how about it, things went well last night, right?" ”

"Okay, how did you sleep?"

"I started to worry about you, I didn't dare to sleep", she said, "Later, I saw you and Miss Shen coming back from the window, entering her house and driving out other people's bodyguards, and then I was down-to-earth and slept soundly." ”

"You're relieved to see that I'm back?" I smiled, "That's sensible." ”

"I'm relieved to see you're back," she looked at me wickedly, "and then I saw you go into her room and get into her bed, and I'm sure." ”

I looked at her, "I went to her bed, but I wasn't like her, she was injured in the mountains last night, and I went to heal her." ”

"She's hurt internally?" Zhou Yan stopped laughing, "Is it so serious?" What's going on? ”

I told her a brief account of what happened last night.

"In the Nine Palace Dome are evil spirits and Yin Face Demons, and in the Fourth Dimensional Stronghold, there are four demon spirits", she pondered for a moment, "Brother, this is a bit of a coincidence, right?" ”

"I think it's a bit of a coincidence," I said, "and it seems to be a specially designed number, not like it's natural." Even if Jiuqu Ruyi summons evil spirits, if there is no special arrangement, it will not be so tight, especially the Mind Devil and the Soul Eater Demon, the order of coming out is very particular, which is even more strange. ”

"According to Shen Qing, when Shen Yulong sealed this basement more than a hundred years ago, he should have been in a hurry," Zhou Yan said, "Can you have enough time to make this special arrangement?" ”

I thought for a while, "It's not impossible, because more than a hundred years ago, it was arranged from top to bottom, and it was theoretically fine." I just think it's too coincidental, a little bit random, so I wonder if there's something deliberate in it. ”

"Does that affect the business?" She asked.

"There won't be a big impact, but it involves the route of the basement labyrinth," I said, "The evil spirits of the Nine Palace Dome rushed out in one breath except for the Yin Face Demon, which means that the location of the Yin Face Demon is near the secret passage leading to the backbone of the Four Dimensions from the Nine Palace Dome." And the four demon spirits came out in turn, indicating that the four rooms in the backbone of the four dimensions each have their own formations and contain each other, and if you want to find the secret passage to the treasure room, you must make a fuss about it. ”

"Secret Passage...... It's all secret passages", Zhou Yan patted his forehead, "I'm almost confused, brother, let's draw it and study it, okay?" ”

"Okay, then you go find a pen and paper."

After the drawing was finished, Zhou Yan took a closer look, "Brother, isn't this just an ordinary nine-palace diagram?" ”

"That's right, but think about it, if we imprison a large number of evil spirits and a shadow demon inside, once the general seal on the outside is opened, we can let them fish out in such a layout?"

She thought for a moment, "There must be spirit runes on the walls of these rooms, and it's impossible to get through them...... Unless it is to settle in the middle palace, and then divide the remaining eight palaces into three formations, which are interlocking with each other and restricting each other. In this way, after the general seal outside is opened, one of the formations is broken, and then the other general seal is triggered like a domino, and the three seals are unlocked in turn in a short period of time, so that those evil spirits can gather together and rush out in one go. ”

"Yes," I nodded, "I don't know exactly what the layout is right now, but it should be like this." ”

"In that case, the Yin Face Demon should be in the last formation," she continued, "The rest of the evil spirits in the first two formations, as long as they find out the order of the three formations, then they can find the secret passage to the backbone of the four dimensions!" ”

I smiled slightly, "Clever! So this task is handed over to you. ”

She was stunned, "Me? Brother, you're not kidding, are you? I'm only half a hanger, how can you make me embarrassed by such a difficult task? ”

"Although you are a half-asser, you have been in the Tan family's formation since elementary school", I said, "When I studied mathematics, the starting point was Yili, not the layout. So, it's a lot easier for you to study than I do. Besides, I have to enter the Nine Palace Dome in person at noon, are you embarrassed not to share some worries for me first? ”

"Okay, I'm embarrassed", she looked at the picture and nodded, "Then I'll try, if you can't study it in an hour, then you can only do it yourself." ”

"Okay, you study first, I'll ask Feng Yong to get something to eat", I turned and walked out of the room.

Zhou Yan has one thing I like, that is, she is serious, whether she studies things or refining objects, she basically devotes herself to it, and forgets to sleep and eat.

Breakfast came, but she didn't eat a bite, she kept looking at the nine-palace diagram and pondering, drawing with a pen from time to time, and found that it didn't work, so she drew another nine-palace diagram next to it. By the time I finished breakfast, she had already drawn two blank sheets of paper, and she had taken the third.

I looked at my watch, and more than forty minutes passed.

"Otherwise, I'll go get something to eat," I whispered.

"No, I don't believe in this evil!" She pushed me aside, "You go outside and play with Feng Yong." ”

"Didn't you mean an hour? It's almost there", I remind.

"Two hours!" She said, "Just a little eyebrows, don't bother me, you play first, I'll call you if you understand." ”

I sat down next to her, "Then you think, I'm here watching." ”

She ignored me, and her mind had already been drilled into the Nine Palaces Diagram.

After a while, I picked up one of the drawings and was about to study it with her, when she suddenly slapped the table, "Got it, I got it!" ”

"Got it? Let's talk about it! ”

She leaned over to me and pointed to the diagram in her hand, "Brother, you see, the eight palaces are divided according to four-three-one, for example, this place is the entrance to the nine-palace dome, so from here, according to the principle of the Tai Chi division system, the four palaces on the right hand side are where the first formation is located......" She explained to me in detail.

I thought about it for a moment, "Well, I think that's pretty much it. Okay, Shen Qing and I will go up the mountain at noon, and we will follow your picture to find the secret passage. ”

"Huh?" Zhou Yan was stunned, "Brother, you trust me so much?" What if there is danger? ”

I smiled, "You're my assistant, who can I trust if I can't trust you?" And what you just said makes a lot of sense, and I don't think there's anything wrong with that. ”

She was silent, looking at the picture and then at me, her eyes were complicated.

"What's wrong with you?" I looked at her, "Are you alright?" ”

"Brother......" she lowered her head, "Except for my dad, you are the only one who trusts me so much......"

Listening to this, it makes people feel a little sad.

"I trust you because you're worth it," I smiled faintly, "silly girl." ”

She wiped the tears from the corners of her eyes and smiled reluctantly, "Brother, thank you." At noon, I will go up the mountain with you, and in case this picture is not right, I will go into the Nine Palace Dome to find you!" ”

I shook my head, "This secret passage is the secret of the Shen family, although you know it, but if you follow, Shen Qing should not be at ease." Now that she is doing something, she will not do anything to us, but what about after she is done? If such a secret is known too much to outsiders, no one will be sure. ”

"That'...... Then will she be relieved if I don't go? She frowned, "Brother, if she is such a person, we have to plan early!" ”

"As long as you and Feng Yong don't go up the mountain, she won't embarrass us," I said, "As for me, she won't worry, she trusts me, but she doesn't trust you." ”

"Oh, then I see", she nodded, "Brother, you must be careful, since there is a mechanism in there, it must be dangerous." ”

I took the picture in her hand, "With this, you don't have to worry about the mechanism or anything." A treasure vault like this will only trigger the danger if the route is wrong, and as long as the road is right, there will be no problem. ”

She breathed a sigh of relief, "I hope I'm not mistaken." Brother, you go in at noon, when will you come out? ”

"The air in the basement is not good, and it must come out within half an hour, otherwise it may be poisoned," I said, "She has a gas mask, but when she wears it, she is less sensitive to the surrounding atmosphere, and it is more dangerous." ”

She smiled, "You wait, I'll go get you something." ”

"What's that?" I asked.

"You'll find out in a moment!"

After a while, she came back, holding a delicate small jade tablet in her hand, "This is ice chalcedony, it has been refined for more than eight hundred years, it has been refined by a special method, it can detoxify and ward off evil spirits", she said, "You hold it under your tongue, you are not afraid of any poisonous smoke and miasma." ”

I took it and looked at it carefully, it was a crystal clear piece of jade, very beautiful, like a piece of ice. I've seen a lot of chalcedony, but it's really rare like this, especially since it's an object that has been passed down for more than 800 years, so it's a rare treasure.

"Who gave you such a valuable object?" I asked.

"Of course it's my dad," she said, "It's an old thing from the Tan family, and my grandmother wore it since she was a child, so she lived to be in her nineties and still look like someone in her fifties." According to the legend of the Tan family, eight hundred years ago, an ancestor of the Tan family refined more than 100 pieces of chalcedony, and only two pieces became them, one in the shape of a blood heart and the other in the color of ice. He passed on the blood chalcedony to his youngest son, and the ice chalcedony to the eldest daughter-in-law of the long house. My grandmother is the descendant of the eldest daughter-in-law of the long house, she lost her mother when she was a child, so her father loved her very much, and when she got married, he made an exception to take ice chalcedony as a dowry, so that she was taken out of the Tan family. ”

I took her hand and placed the ice chalcedony in the palm of her hand, "This object is too valuable for me to use." ”

"No matter how valuable it is, it's just an object, you can take it", she stuffed it back into my hand again, "Nothing is as important as safety, for someone like Shen Qing, it's not worth throwing our lives in it." ”

"This ice chalcedony can rejuvenate the face, aren't you afraid that I will break it?" I looked at her.

"Don't tease you, if this thing is really so fragile, can it be passed on for more than 800 years?" She smiled, "Besides, as long as you're safe and sound, even if you smash it, I'm willing!" ”
