"Like this Echo Alley. Pen Fun Pavilion wWw. ｂiquge。 info" Li Yuanzheng pointed to the place where everyone was standing, which was an alley between the two houses.

"There are a lot of clay jars buried under this alley, which can not only hear the echo but also prevent fire; there is a thorough alley between the entrance, which deliberately separates the whole house from the bottom, and cannot write to the bottom, this move is to avoid suspicion, because the pen to the bottom is said to be an attempt to claim the emperor. ”

"There is also an eight-foot alley, and each house crosses the eight-foot alley, which is specially used for the owner to pick up and drop off at the door of the house when the sedan chair and carriage go out. Li Yuanzheng led them into an alley that was sideways, explained.

"Also, we will be able to get there later, there is a separate alley between the main house and the kitchen in the tukuli, and the doors are not facing each other, so as to prevent fires from spreading to each other. With Li Yuanzheng's explanation, Liu Ruyan observed every detail of the earthen library more carefully, and was pleasantly surprised to carefully observe every plaque, every house, and the trend of each patio and sewer.

Li Yuanzheng saw Liu Ruyan looking at the ground and the patio from time to time, so he asked strangely: "Rourou, is there money on the ground to pick up?"

Liu Ruyan glanced up at him, as if asking him, and as if talking to herself: "How is the underground water system of the earthen reservoir built?"

Li Yuanzheng listened, smiled and said: "You are really observant, not simple, in fact, the underground waterway of the Wangshan earthen reservoir is also one of the magic of the earthen reservoir, the large houses that are several miles longitudinal and horizontal, there is no obvious ditch, for more than 100 years, the earthen reservoir has never been blocked by the ditch and water accumulation, nor because of the rain ditch and water accumulation, and, from the original dilapidated ground excavation of the official hall, this has not found the direction of the distribution of the ditch, so the drainage system of the Wangshan earthen reservoir is also one of the magic of the Wangshan earthen reservoir. ”

"Magic? There must be a certain way, magic is just your propaganda, I believe that this sewer structure is complex and cleverly conceived, and it will never be a mystery as you say. Liu Ruyan smiled and said, maybe she was tired of carrying her bag, or maybe she did it intentionally, she reached out and stuffed her bag to Lin Gang.

Li Yuanzheng saw it in his eyes, glanced at Shang Yuemei, and nodded secretly, Shang Yuemei also smiled and nodded lightly.

"The master is the master, we are just a grade off, people watch the doorway, we can only watch the excitement, Lin Gang, you have to study hard, you have to ask our great designers for advice, otherwise, your bag is in vain." Shang Yuemei deliberately smiled in a weird way, the purpose was to do everything possible to pierce the layer of window paper between them, as long as there was a trace of progress, she would add fuel to the fire.

Lin Gang was only a junior high school student, and he couldn't understand the mystery of the structure of the Wangshan earthen library and the reason why Liu Ruyan was fascinated by the Wangshan earthen library.

"I can't hide anything from you, okay, I'll explain it to you. Li Yuanzheng saw that his efforts had achieved some results, and he was happy to hear it. "Rourou you find no, the height of the ground in each courtyard increases by about 5 centimeters, which can prevent the sewer from accumulating, and at the same time, the floor of the patio is lower than the other ground, sloping to the south, in the lowest depression there is a square shape, the top is carved with animal figures, or rabbits, or turtles, very beautiful ashlar blocks, the bottom of the ashlar is hollowed, the four sides are left with seams, the entrance to the drainage system is covered, and all the water finally converges into the crescent pond at the front of the house. ”

"If the mud clogs the sewer, how do you clean it up?" asked Liu Ruyan as she broke the casserole.

"The sewer is designed according to the precise calculation, the design of a reasonable width, mainly relying on the impact of the water to clean up the silt, you should understand, the waterway is wide, the silt is gathered together, the impact of the water is small, the silt is not easy to wash away, it will be deposited there for many years, the sewer is naturally easy to block, if the impact is large, the silt can not be retained, and the purpose of cleaning is achieved. Li Yuanzheng explained very incisively, and Liu Ruyan suddenly understood.

Director Pan, who is responsible for the restoration of the Wangshan earthen library, is Li Yuanzheng's teacher, and he also came to them after finishing his own miscellaneous work, and explained in more detail the vast history and culture of the Wangshan earthen library, which is not only the miracle of the Wangshan earthen library itself, but also the various cultures, customs, and customs associated with it, which can be said to be a comprehensive cultural history of the Qing Dynasty.

Here, Liu Ruyan learned a lot of things that were not in books, enriched her knowledge of history and culture, and returned to Nanjiang with satisfaction and happiness.

Back at home, Lin Gang took a shower, habitually turned on the computer, hung up QQ, and saw who was online and could chat for a while.

An avatar was flashing, and when Lin Gang saw that it was Liu Ruyan, he clicked on the link and typed a few words in the dialog box.

"Are you still online so late? I played all day today, and I rested early. ”

Seeing Lin Gang's concerned words, Liu Ruyan's heart was very warm.

"It's been a big day today. Thinking of the skin-to-skin kiss of Shangtianling, the careful care of the winery, and the personal care of Wangshan Tuku, Liu Ruyan sent her feelings with satisfaction.

“？？？？？？”

Seeing the other party's series of question marks, Liu Ruyan didn't explain, but still thought that she should give a hint.

"If you don't understand, forget it, thank you for carrying me down the mountain today. At this time, Liu Ruyan was already immersed in the double ocean of knowledge and love, wandering happily, although I don't know how deep the ocean of love is.

"Don't thank you, thank me again, I'll be ashamed. ”

Seeing this line of words, Liu Ruyan frowned, she didn't understand the meaning.

"I can't understand anything. Liu Ruyan couldn't help but ask.

"That's the most important thing any man should do. ”

Liu Ruyan saw Lin Gang's words, and a faint flush hung on her face again, but she still felt a little vicissitudes in her heart, she didn't know what Lin Gang thought, her expression was already clear, you can't ask a girl to say "I love you" directly.

If Lin Gang is like this, does he want to indulge in his old ways, or does he feel inferior, is he emotionally an elm head, why doesn't he show it at all? Does he really want a girl to send a message that a boy will take the initiative to confess?

Lin Gang here was also nervous in his heart. Today's Liu Ruyan's actions, she is not an elm head, it is impossible not to be indifferent, at that time, she was also in the spring heart, intoxicated with beauty, but this intoxication only existed for a moment, Lin Gang still had to return to reality. Liu Ruyan is a highly-educated, high-quality, high-income elite, and she is beautiful and moving, how can I be worthy of others? If I brazenly pursue her, don't you think it is particularly absurd? Thinking of this, Lin Gang sighed heavily.
