"What is this room for?" Meng Guyun entered a larger stone house under the leadership of Lin Xin, as soon as he entered the door, Meng Guyun was attracted by dozens of large and small, different shapes of sand tables in the room, these sand tables were made extremely meticulously, obviously the maker spent a huge amount of time and effort, which not only built mountains, hills, plains, basins and other natural buildings, but also cities, villages and towns, passes, fortresses and other artificial buildings, and simulated rivers, lakes and seas with mercury, and used mechanical devices to make mercury flow and circulate, making people look at it at a glance and lifelike.

"What are these things called, and what are they for?" Meng Guyun asked Lin Xin with great interest while looking at the model of the landscape city in front of him that he had never seen before.

"Hmm..." Lin Xin also carefully looked at the environment in the house, and when she heard Meng Guyun's inquiry, she fell into deep thought, and Meng Guyun had all her concentration on the sand table in the room, and she didn't notice Lin Xin's expression at all.

"This is the Yanfeng Pavilion, which is used by the mountain chief for military teaching on weekdays, and these things should be the sand table model that the white soldier and the mountain chief once said, which were built by the master himself according to the famous mountains and rivers and the city and the city during his travels." Lin said thoughtfully.

"Should? Don't you know. Meng Guyun said strangely, but the movement did not stop, reaching out to touch the mercury of the simulated river in the sand table.

"Be careful!!" Lin on the side was frightened and hurriedly stopped Meng Guyun.

"Huh? What's wrong? Lin Xin's screaming really frightened Meng Guyun, stopped his movements, turned his head and stared at Lin Xin, his eyes full of doubt.

"Whew..."Seeing that Meng Guyun withdrew his hand, Lin Xin breathed a sigh of relief and explained, "I once heard the white soldier Shaoshan Commander say that the silver water-like object in the sand table is called mercury, which is highly poisonous, and a little bit can kill people. Moreover, the people in the fort have said many times that the mountain chief is not allowed to touch his personal belongings without permission, so you should not disturb them. Lin Xin instructed.

"I heard, I heard, don't you know it yourself, why did you hear about it?" Meng Guyun was not convinced, and Lin Xin said that mercury was highly toxic, but he said that he heard from others, he wanted to say that maybe Gu Yuzi didn't want others to mess with the things in the room at will, so he deliberately made up an explanation to scare you cowards, but Meng Guyun thought about it, Gu Yuzi is so powerful, if it is true, it is really extraordinary, he hesitated for a while, and did not dare to move casually.

"I really don't know, Yanfeng Pavilion doesn't have the permission of the mountain chief, except for the young mountain chief, no one else can come in without permission, and I actually have the first time today..."

Meng Guyun didn't pay attention to these details, and said strangely, "Didn't you say that military lectures are held here, why don't you let them in?" And who is the young mountain chief you said, is it the son of the mountain chief? Meng Guyun saw that Lin had mentioned Shaoshan Chang many times in his heart, and couldn't help but ask.

"The white soldier Shaoshan Chang is not the son of the mountain chief, just like us, he was also brought up the mountain by the mountain chief, but later the mountain chief accepted him as an apprentice, so we all call him the young mountain chief. As for what nationality the young mountain chief is, why he went up the mountain, and who else is in the family, I don't know. Lin Xin explained that she was afraid of asking him about the life of the white soldier Shaoshan Commander again, so she hurriedly added another sentence.

Meng Guyun was curious, and was about to inquire about the situation of this young mountain chief called Baibing, but when he heard the second half of Lin Xin's words, he couldn't help but be disappointed in his heart, so he had to give up.

"Aren't you the apprentice of the mountain chief? Why can't you just come in and out of here? Meng Guyun saw that Lin Xin was so mature when she spoke at a young age, and she was so familiar with Gu Yu's Castle, and Gu Yuzi asked her to accompany her to visit the castle, only to say that she must also be Gu Yuzi's disciple.

"How can I have that blessing... The mountain chief is extremely strict with the requirements for accepting apprentices, and I don't think I have the qualifications to be an alternative. Lin Xin said gloomily, "And I heard that the mountain chief once made a rule that he would only accept three apprentices in his life, and I knew that my qualifications were mediocre, and I never dared to have such extravagant hopes." Lin Xin lowered her head and said softly.

"How many apprentices has the mountain chief accepted?" Meng Guyun's heart suddenly became hot and asked.

"I've already received two, one I heard that the mountain chief is an apprentice who has not yet lived in seclusion in front of Yannan Mountain, as for who it is, where is it now, why no one knows why he has never been to Yannan Mountain, and the mountain chief never mentions it, and the other one is the white soldier Shaoshan Chief, he worshiped the mountain chief as a teacher three years ago."

"Then why are the people in the castle..."Meng Guyun thought to himself that if the people in Gu Yubao were not Gu Yuzi's disciples, why did they feel that they could all write and behave properly, and they also had martial arts, Gu Ming, who often took care of him, was equipped with a long sword, and felt that his kung fu was not weak, it stands to reason that everyone in the castle was just a refugee orphan adopted by Gu Yuzi, and they didn't even eat three meals in this troubled world, how could they have the opportunity to read and write and practice martial arts?

"That's because the mountain chief will screen us every half a month to see which aspects of us are more prominent, and then classify, he will give public lectures every three or five days when he is on the mountain, so that the people he chooses will go over to listen to the class, I have been fortunate to listen to the mountain chief's nine cultural classes, the mountain chief's class is wonderful every time, but my qualifications are limited, and I don't absorb much, so the mountain chief has not asked me to listen to the class again in the past three months." Lin Xin saw Meng Guyun's doubts, and explained softly, when he mentioned that he had taken Gu Yuzi's nine classes, his face showed a hint of joy, but when he said it, his face darkened again.

"In addition, the chief of the mountain also encouraged us to consult and visit each other, so the people in the fort, in addition to the daily work, will learn from each other according to their own interests and strengths."

Meng Guyun thought to himself that this was the case, no wonder the people in it gave people a different feeling, it turned out that there was such a good learning atmosphere, which was completely different from what he felt when he was in Tianmeng Mansion; When he was in Tianmeng Mansion, except for his father, mother, eldest brother and Steward Zhang, almost everyone was respectful to him, he actually didn't have many people to talk to, and in Gu Yubao, although everyone was indifferent on the surface, they were very well-behaved, and Gu Yuzi's ability was unfathomable, although he didn't say it, he was already very admired in his heart, so he was more interested in Gu Yubao.

"Master Meng, the mountain chief commanded, your body has not yet recovered, and proper walking will help your body recover, but the time should not be too long, otherwise it will be harmful to the body." Meng Guyun still had a lot of questions to ask Lin Xin, but he was interrupted by Gu Ming, and when he heard that it was Gu Yuzi's order, he had no choice but to give up.

"Lin Xin, you go back first, I will take Dream Gongzi back to the house." Gu Ming turned to Lin Xin and said.

"Yes." Lin Xin gently agreed, and Shi Li was ready to leave.

"Lin Xin, come and play with me again when you have time, I still have a lot of things to ask you." Meng Guyun finally remembered Lin Xin's name and greeted warmly,

Lin Xin's face turned red, but she didn't answer, and went away.

Meng Guyun had lunch, because his body had not yet recovered, he chatted with Lin Xin for nearly two hours in the morning, and his body did feel tired, and the wound was also a little painful, so he lay on the bed to rest according to Gu Yuzi's instructions. Meng Guyun's personality doesn't like to be guarded, and he is no longer in serious trouble, so there will be no emergencies, so Meng Guyun is the only one in the room, and a white-clothed attendant is arranged to guard outside the house, so that he can shout if he has anything.

Although Meng Guyun felt very tired physically, he was full of thoughts, constantly thinking about his feelings and experiences on Yannan Mountain these days, and would also compare the life in Tianmeng's Mansion with the lives of everyone in Gu Yu Fort, which made him even more interested in the life in the castle, only feeling that Gu Yu Castle was an endless mystery, and Gu Yuzi was an unfathomable character, and suddenly he felt that he was not as disgusted with learning and practicing martial arts as before; After a while, his father's strictness, his mother's favor, his eldest brother's teachings, and his heart's deep attachment to the happiness of his family together, several thoughts were constantly intertwined, and he also felt more and more tired, and fell asleep unconsciously.

In the next four days, after breakfast and lunch, Lin Xin will come to him according to Gu Yuzi's instructions, Gu Yuzi will change to check Meng Guyun after dinner every day, and the time of stay will be determined according to Meng Guyun's physical condition, but basically he will chat with him for an hour, and the topics are becoming more and more extensive, in addition to the travel stories that he talked about before, the strategies of various countries, and classic war examples, combined with Meng Guyun's visit to Gu Yu Fort, he will also talk about thoughts, martial arts, the art of war, astrology, medicine, architecture and other topics, especially thoughts, It is a topic that Sikong Miao and Meng Guyun explain the most and in detail, so that he has his own new definition of this troubled world, and he can better understand the efforts and dedication made by his father and eldest brother in hoping that this troubled world can end as soon as possible.

After many days of getting along with Lin Xin, the relationship between Meng Guyun and Lin Xin has become much closer, although Lin Xin's tone to Meng Guyun is still cold, but her attitude has changed significantly, she is already clear about Meng Guyun's character, many times without waiting for Meng Guyun to ask, she will take the initiative to make a detailed explanation, and occasionally listen to Meng Guyun talk about some naughty and interesting things he has done, on the surface I don't think so, but every time I listen carefully, sometimes I can't help laughing, but I will immediately return to a cold expression, Meng Guyun looks at it in his eyes, and thinks it's funny, is even more enjoyable, and often teases her with interesting things.

"It's almost lunchtime, so let's stop here today." Lin Xin took Meng Guyun to visit the place where they studied and practiced martial arts on weekdays, and said to Meng Guyun.

"Okay, I'll come here in the morning, and I'll come back to you after lunch." Meng Guyun is generally familiar with the castle, and his injuries have basically healed, plus Gu Yuzi takes care of him, so it is very convenient to act in the castle.

"Forget it in the afternoon," Lynn said again.

"Why, there are so many places in the fort that I haven't visited." Meng Guyun said strangely, "Don't worry, I'm fine." Meng Guyun thought that Lin Xin was worried about his injury, and hurriedly added.

"The mountain chief said that your injuries are no longer serious, and you can go down the mountain tomorrow, so, so I think it's better to rest in the afternoon." Lin thought about it again and again, couldn't stand Meng Guyun's blazing inquiring gaze, and said in a hurry.

"Ahh Meng Guyun and Lin Xin visited Gu Yu Fort during the day these days, and he was full of curiosity about all things in Gu Yu Fort, and although Lin Xin was cold on the surface, Meng Guyun had a fiery personality, and the two of them were cold and hot, and they were quite compatible, although Meng Guyun was loved by thousands of people when he was in Tianmeng Mansion, there were almost no playmates of similar age, but fortunately, he was quick thinking and good at having fun by himself, so he was not boring, but compared with the time in the past few days in Yannan Mountain, the days in Fuzhong were boring and much more boring. These days in the fort life is interesting and fulfilling, the Gu Yu Fort has also changed from strange to familiar, child nature, he has long lost the original eagerness to go home, unconsciously, after he woke up, he has lived in the mountain for seven days, at this time I was reminded by Linxin that I will leave tomorrow, and I can't help but cry out.

"If you want to stay, you can apply to the mountain chief..."Lin Xin saw that Meng Guyun didn't speak, how could she know his complicated feelings, she really didn't want Meng Guyun to leave in her heart, and she felt embarrassed to stay directly.

There are already regulations in Gu Yu Castle, unless the other party takes the initiative to tell him, it is not allowed to inquire about other people's life history privately, Meng Guyun except for wanting to tease Lin Xin on the first day He revealed that he is a native of Daheng Heng'an, and has an elder brother, because of the regulations in the castle, he has never mentioned his own life experience, so Lin Xin does not know the identity of Meng Guyun's general son, only that Meng Guyun is the same as himself, he is also an orphan, or his family is in the middle of the road, and he happened to be rescued by the mountain chief, until he received a notice in the morning that he did not need to accompany Meng Guyun tomorrow, Today was the last day, and after questioning, I learned that Meng Guyun still had a family, and he was going down the mountain tomorrow, and he was very disappointed in his heart.

"If you don't worry about your brother, you can also apply to the mountain chief, and if the mountain chief agrees, you can pick up Yannan Mountain together." Lin Xin saw that Meng Guyun still didn't speak, and suddenly remembered that he had said that he had an older brother, thinking that he was worried about his brother, and whispered a suggestion.

"Okay, I'll talk to the mountain chief in the afternoon, if you can let me stay on the mountain for a few more days." Meng Guyun couldn't figure it out for a while, but with Linxin's character, it was not easy to keep him twice, and he definitely didn't want to go down the mountain so quickly.

Lin Xin saw that he just said that he was discussing with the mountain chief to go down the mountain later, and did not agree to stay, she didn't know the inside story, and she was a little unhappy in her heart, but Meng Guyun was willing to stay on the mountain for a few more days, and she was still very happy. The two agreed with each other that a word was a deal, and they promised that Lin Xin was relieved to go.

"Brother Gu, please tell the mountain chief, I have something to discuss with him, can you invite him to come over in the afternoon, or I will go over to find him?" Meng Guyun hurriedly used lunch, and before he had time to put away the dishes and chopsticks, he immediately asked Gu Ming. He knew that Gu Yuzi usually came at night, so he was naturally unwilling to wait for an afternoon, and he didn't say anything to Mr. Gu Yu for a moment, and he couldn't rest assured for a moment, so he wanted to discuss it as soon as possible.

"Yes, but it's meal time, I'll go over and ask the mountain chief later." Gu Ming should admit it.

"Thank you Brother Gu so much." Meng Guyun hurriedly saluted and thanked him.

"Little brother is polite, it's just a gesture." Gu Ming returned the salute gently, said lightly, then packed up the dishes and chopsticks, turned around and went out.

After Gu Ming went out, Meng Guyun only felt that the time was difficult, and after about half an hour, Gu Yuzi did not let anyone accompany him, and came alone.

"Little brother, what are you looking for me, but I'm not feeling well." Gu Yuzi said with concern.

"Thank you Mr. for your concern, the kid is in good health. I asked him to come over today because I would like to discuss other things with him. "Dream Guyun gets straight to the point.

"Oh, little brother has something to say." Gu Yuzi didn't seem surprised and smiled.

"That's right, since I was attacked, fortunately Mr. rescued, not only left me in the fort to recuperate, let people take me to visit Gu Yu Fort during the day, Mr. also personally taught me the world's major events, the way of being a person, so that I can open up my thinking, benefit a lot, Meng Guyun here sincerely thank Mr." After speaking, I sincerely bowed to Gu Yuzi.

Gu Yuzi helped Meng Guyun up, knowing that he still had something to say, so he didn't answer, just listened quietly.

"So," Meng Guyun was a little embarrassed, "Gu Yu Fort is like a small world, completely different from the world I am familiar with, everyone performs their own duties, helps each other, studys, and works, all of which are very attractive to me, so I want to live in the fort for a few more days, and I hope that Mr. Gu Yu will be successful." "Meng Guyun has grown so big, in addition to being coquettish with his mother and eldest brother, this is the first time to beg for someone seriously, he is really not used to talking in such a literary manner, but now he doesn't have time to think so much, I just hope that Gu Yuzi can agree to his request.

"No." Gu Yuzi did not hesitate at all, and categorically rejected Meng Guyun's request, this answer was greatly unexpected by Meng Guyun, since he went up the mountain, Gu Yuzi cared about him, took care of him, and chatted with him, but he didn't expect to be so unsympathetic at this moment.

"The little brother has been in the valley for seven days, and I believe he already knows the rules in the valley." Gu Yuzi saw great disappointment and disbelief in Meng Guyun's eyes, and gently explained, "Everyone in Gu Yu Fort is an orphan and a displaced refugee from various countries, and they are all homeless, so they will take them up the mountain in the next place, and leave them to live in the valley, so that they can stay away from the pain of displacement, this is the original intention of creating Gu Yu Fort in Xia, and it is also the unwritten rule of Gu Yu Fort for ten years, but the little brother is the son of the general, and his background is illustrious. And the high fever continues, there is a worry about life at any time, in the downstream experience, the medical materials are limited, I am afraid of missing the life of the little brother, so I took the risk to take the little brother up the mountain, and let the little brother recuperate in the fort, now the little brother has healed, according to the regulations of the fort, it is difficult to continue to keep the little brother in the fort. Besides, the little brother has been away from home for ten days, aren't you afraid that your mother will worry about you? ”

Meng Guyun's heart continued to sink, and when Gu Yuzi said this, it seemed that it would be difficult for him to continue to stay on the mountain.
