You can go up to the hall and down to the kitchen.


    Beat cockroaches and fight monks.


    Not to mention the standards brought by Princess Changle to the new generation of women, among the waves of the legend of the White Snake, the ink magazine has benefited the most.


    "Overprint!"


    "Overprint!"


    With the continuous spread of the biography of the White Snake, ink periodicals, which had a huge circulation, once again fell into a situation of short supply.


    In this era of extreme lack of entertainment activities, the sensation caused by the more mysterious and bizarre biography of the white snake is better than Liang Zhu.


    For a while, ink magazines worked overtime to print. As soon as they were printed, they were transported to all parts of the Tang Dynasty by carriages. Confucianism magazines, which originally had a small market share, were squeezed out of shape, so that the sales volume of the new issue of Confucianism magazines was even bleak, and even the number of ink magazines printed at one time could not match.


    Beside Qujiang River, Li Yun read the new issue of Ink magazine with interest. These wonderful stories can''t be seen in Xiangfu''s seclusion.


    "The Mohists are so lucky that they let Princess Changle use them deeply." Li Yun couldn''t help sighing.


    The old servant nodded approvingly and said, "it''s a pity! If Mozi really understands everything and enters the Buddhist school, my Mozi school will be peaceful."


    Li Yun could not help but be silent. If he had agreed with this idea before, after all, Xiangfu thought that the Mohist family had abandoned the idea of Mohist saint and abandoned the book to the end, which was the most unorthodox Mohist art. But on the contrary, even the Buddhists would compete for the supreme position of Merton, which would be the embodiment of the value of the Mohist family. If Merton really joined the Buddhism, Is it really good for Mohism?


    In addition, although Mohist Zi abandoned the political concept of Mohist saint and devoted himself to the development of Mohist technology, it is much better than Deng Ling''s line, which has been reduced to street art, let alone the Mohist village''s Mohist technology once again made Mohist famous and embarked on the road of revival.


    "Maybe Mohism is the right way?" this idea has been lingering in Li Yun''s mind. Compared with the reclusive Xiangfu family, the vibrant and changing Mohist village is probably the weather of Mohism in his mind.


    But he soon put the idea out of his mind. Now the most important thing he has to do is to build and close the bridge in front of him.


    With the long steel cable of Qianjin arm lifting a huge stone and firmly clasping it in the last gap of the arch bridge, the arch bridge built by Li Yundu was finally completed.


    "Good!" the old servant looked at the closed bridge and said excitedly, "young master, if you build this bridge, you will become famous in one fell swoop."


    In his opinion, the arch bridge built by Li Yun is not only extremely short in time, but also with the help of Mohist Qianjin arm, the stones used in the arch bridge are more huge, and the bearing capacity and firmness are better than ordinary arch bridges, which is also the most proud place of old servants.


    Li Yun''s face could not help showing a trace of pride. When he first designed the arch bridge, he knew that the Qujiang bridge built by Mohist Zi was originally an arch bridge. It was because of the sudden popularity of Mohist four-wheel carriages, especially the surge in the weight of four-wheel freight vehicles, that the Qujiang Bridge collapsed rapidly.


    When he designed this arch bridge, he had been keenly aware of the problem of cargo capacity, and had focused on increasing the bearing capacity of the arch bridge. It can be said that this bridge is better than all arch bridges in the world in terms of bearing capacity.


    However, his eyes followed the river and looked at the unique beam bridge vaguely visible in the distance. A trace of worry flashed in his heart. Although he had confidence in his own arch bridge, he faced an unknown beam bridge. There are always lingering clouds in his heart.


    Qujiang bridge.


    Wu Meiniang, the eldest martial sister of the Mohist family, put away her usual domineering spirit, shrunk her head like a little quail and followed Merton behind her.


    "Congratulations, master. Now the Qujiang bridge has finally been completed. People on both sides of Qujiang will surely remember the great kindness of master in the future." Wu Meiniang flattered while looking at the Qujiang bridge that was about to be completed.


    Since she obeyed Shiniang''s arrangement, she severely punished Shiniang. Although Shiniang protected her from punishment, all Shifu didn''t know where to get some difficult questions. She didn''t let her suffer by taking the opportunity of teaching disciples.


    Merton snorted coldly, "the Mohists act to show what they have learned, not for the kindness of the people."


    "The Mohist school is high in righteousness, the master is wise! I admire you." Wu Meiniang quickly flattered her.


    Merton''s face relaxed, pointed to the Mohist children who laid cement on the bridge deck and said, "as a teacher, test you again. Do you know why these workers want to separate these cement into blocks."


    Wu Meiniang couldn''t help but look bitter and didn''t dare to slack off. She quickly focused on the gradually solidified concrete bridge deck in front of her, and couldn''t help falling into meditation.


    The biggest advantage of cement is that it can set infinitely as long as the raw materials are enough. However, the cement in front of us is different. Instead, we use cardboard to separate the originally flat cement road on the bridge into blocks the size of a square meter.


    Moreover, according to the children of the Mohists, this was specially ordered by the master. Many people also complained that it took too much work and was not beautiful. How much was the original flat road. Not only that, Merton also ordered the extremely smooth road that was originally painted to be deliberately rough.


    "This is to enhance friction and prevent slipping!" Wu Meiniang felt a move in her heart. She had just come into contact with Mohist theory. What she was most interested in was all kinds of machinery. What she learned most was Mohist mechanics. Naturally, she knew the reasons. However, she was puzzled about the measures to separate the cement road.


    "I''m stupid. Please give me some advice." after a long time, Wu Meiniang had no choice but to bow her head and ask for advice.


    Merton couldn''t help showing a trace of pride, and then hid his positive color and said, "if you want to really understand the truth, you need to learn the new knowledge of Mohism, the way of distance, and being a teacher will teach you a new lesson."


    "The way of distance!" Wu Meiniang suddenly looked solemn. Although Merton didn''t have many opportunities to teach her in person, he benefited a lot from every lesson.


    "Since ancient times, people all over the world have racked their brains to shorten the distance and avoid detours, and the bridge is one of the most dazzling masterpieces. The land of a river is no more than tens of feet wide, and the two sides can shout across the air. However, if you want to cross the river, you have to go around dozens of miles before you can have a ferry. Even in summer, when there are floods, the ferry is also extremely dangerous, and the traffic is cut off. It is often after a month, so the bridge Came into being. "


    Wu Meiniang nodded. Recently, in order to study all kinds of bridges, stone arch bridges, beam bridges, single wooden bridges, iron cable bridges,... All kinds of bridges have been dabbled in. Naturally, she knows the importance of bridges.


    "In addition to bridges, there is another way to make the distance not far away, that is speed."


    "Speed!" Wu Meiniang looked at Merton puzzled.


    "In the past, it took more than five days for the carriage to reach Chang''an City from Luoyang, but now the carriage of Mohist school goes from Chang''an city to Luoyang day and night. It takes only six hours. However, the distance will never change, but the time is greatly reduced, which makes the people no longer feel distant. Its mystery lies in speed.


    Psychologically, the distance between Chang''an and Luoyang is not as far away as before. The frequency of people''s exchanges between the two cities has doubled, which is proof. "


    Wu Meiniang nodded solemnly.


    "To study distance, time, distance and, of course, the speed of cars and horses are indispensable. This will be another branch of Mohism besides mechanics." Merton said solemnly.


    "I understand. I''m sure I won''t let the master down." Wu Meiniang solemnly promised, with a trace of disappointment in her tone.


    Merton looked at Wu Meiniang helplessly and said, "do you think the lessons taught today have nothing to do with being a teacher?"


    Wu Meiniang took a careful look at Merton and whispered, "I don''t dare. I''m just stupid. I''m sorry to solve my doubts in the future."


    Morton snorted coldly. He didn''t know Wu Meiniang''s ghost mind. If he didn''t show some real skills, he couldn''t frighten the little girl. Then he snorted coldly: "What I said just now is just a macro distance. However, there are still micro and undetectable distance changes in the micro fields invisible to the naked eye. If it is used properly, it will be of great use. If it is not used properly, even the bridge built by Wanguan will be destroyed unknowingly."


    "Macro, micro!" Wu Meiniang was interested and listened attentively.


    Merton Lang said in a voice: "records of the historian · river canal book:" Shu guards the ice, chisels away from the pestle, prevents the harm of foam water, and passes through the two rivers in Chengdu. " In the pre Qin period, the Mohist ancestors helped Li Bing, the governor of Shu, build Dujiangyan. However, in addition to the torrential river water, there was another problem in Dujiangyan, that is, cutting away from the pestle, which was extremely hard. All skilled craftsmen in the world were helpless. In the face of such a problem, the Mohist ancestors stood up and helped Li Bing dig away from the pestle with a very simple method, that is fire The method of boiling water.


    "The method of fire and water stimulation." Wu Meiniang was shocked. She was most interested in all kinds of secret skills of Mohism.


    "Do you know why a very hard boulder can be easily chiseled out when it is burned by fire and poured with water?" Merton asked.


    Wu Meiniang thought and said, "is it true that the secret is in fire and water?"


    "Yes, later, after many studies, the sages of Mohism found that if an object is very hot, it will increase a little. If it is cold, it will shrink a little. The fire makes the boulder extremely hot, while the water makes the high temperature drop sharply. Between this cold and heat, the shape of the Boulder has changed slightly. My teacher called it thermal expansion and cold Shrink. "


    Wu Meiniang suddenly realized that under the action of heat expansion and cold contraction, the boulder had already been damaged inside, and it could be easily chiseled.


    "Could it be that master separated the concrete bridge deck into pieces to prevent thermal expansion and cold contraction!" Wu Meiniang looked at the cement roads under her feet and looked at Merton with admiration.


    Merton nodded: "yes, the cement is extremely heat absorbing. After being directly exposed to the sun in summer, it will produce high temperature. Although there is no violent method of fire and water stimulation, over time, it will destroy the bridge deck one day and reserve gaps in advance to ensure that the bridge is carefree."


    "Wise master!" Wu Meiniang looked back at Merton''s process of building the bridge. Then she suddenly realized that the principle of heat expansion and cold contraction had been unknowingly applied to the extreme.
