Facts have proved that for the emperor, as long as there are things on his territory, everything is not a problem. In one day, the saltpeter around Chang''an City has been searched out.
The ice produced the next day was enough to supply the whole palace, and the third day was enough to supply the chaotang.
In the legislative Palace
The four ice basins are constantly emitting cold air and a trace of white smoke. The summer heat in the whole hall is completely eliminated and refreshing. Once the ice in the ice basin is melted, there will be palace maids to change into a new ice basin and continue to maintain the temperature in the store.
On the soft couch, Princess Changle, dressed in colorful palace clothes, solemnly took a stethoscope on her face and was giving treatment to empress changsun who was lying on the soft couch. Although a doctor had already treated her, empress changsun still cooperated with Princess Changle very much.
"The mother''s health is all right."
Princess Changle breathed a heavy sigh of relief, took the stethoscope away from empress changsun, loosened the sphygmomanometer and said happily.
Not only did the students of the Imperial College take a field holiday, but even the women''s medical school was no exception. She also took a month''s field holiday. That''s why Princess Changle was able to return to the palace and reunite with the empress changsun.
"Changle''s medical skills are excellent, and her mother feels much better." empress changsun said with a pleased face. As a princess, she didn''t have to suffer from learning medicine, but Princess Changle was happy for her illness. How can this filial piety not move the empress changsun.
"The empress came to laugh at me again. The child has only learned medicine for a few days. It can''t compare with the imperial doctors. However, the empress''s recovery is thanks to these ice pots to relieve the summer heat." Princess Changle said angrily.
Empress Chang sun''s gas illness is most afraid of the hot weather, which often causes the symptoms of chest tightness. Although there was ice in the Imperial Palace in the past, it can only be taken out to relieve the summer heat when it was the hottest. Where would she use ice so extravagantly as now? Without the hot frying, empress Chang sun''s gas illness naturally improved a lot.
"I was going to Jiucheng palace for summer vacation. I was worried that I would be separated from the emperor. With this ice making method, we could reunite our mother and daughter." empress Chang sun sighed. If you want to go to the Jiucheng palace, I''m afraid you won''t be able to come back in a month or two. Princess Changle has to go to the women''s medical school, which naturally can''t follow.
Although it''s cool to go to Jiucheng palace, it''s not easy to travel. Now it''s better to stay in the Lizheng palace and enjoy such a comfortable environment.
"It''s said that the saltpeter ice making was invented by Lord mohou." Changle looked curiously at the ice pots around. Merton''s ice making means in summer surprised her.
Empress Chang sun smiled and said, "who else can make these strange things except him."
"Empress mother, this ice making method is not a strange thing, and it can make her condition better. That''s the best knowledge." Princess Changle said with her mouth.
"Still happy and filial."
The mother and daughter were talking about themselves, and they were happy.
"Touch!"
The door of the Lizheng hall was pushed open by Li Zhi, who was covered with mud stains. Suddenly, a hot air rushed into the hall.
"It''s still cool here after the mother!" Li Zhi rushed to the ice basin in front of the empress changsun and felt the cool air.
"Where are you playing crazy again? How come you''re covered with mud?" empress Chang sun spoiled and wiped the mud off Lizhi''s face with a handkerchief.
"After telling his mother, Merton was digging a pond there, and the child accidentally stuck a little mud?" any child is naturally close to his mother, even if his mother is the queen. If Li Shimin were here, Li Zhi would have hid far away.
"Lord Mo? Why did he dig a pond and raise fish?" Princess Changle was surprised.
Empress Chang sun also showed surprised eyes,
"It''s for swimming and summer vacation! To build a big swimming pool, the water is blue and beautiful!" Li Zhilian said with a gesture.
"Nine younger brothers, what nonsense are you talking about? What''s the matter with the water? Blue?" Changle spoiled and touched Li Zhi''s dirty face. I haven''t heard of the swimming pool. It''s just a place to take a bath, but how can the water used for bathing be blue?
"Is it true? If you don''t believe it, sister Huang, look!" Li Zhi saw that Changle didn''t believe it. He immediately looked anxiously, stretched out his hand, took out a piece of drawing paper from his cuff and handed it to Changle.
"Is this?" Princess Changle took a look, puzzled, and was immediately attracted by the scenery in the painting.
In the spacious pond, a pool of blue water rippled with microwaves. The three sides were covered with white marble slabs, and the last side was covered with sand. Coupled with Merton''s spring and autumn strokes, a beautiful swimming pool painting jumped onto the paper.
Merton''s summer plan was exposed when he accidentally ran into Li Shimin. Merton simply didn''t do it and offered up the swimming pool, so as not to be blamed by Li Shimin in the future.
At the same time, Li Shimin also presented the effect picture of the swimming pool. At the first sight, Li Shimin decided to build a swimming pool in the Imperial Palace, while Merton was undoubtedly arrested and responsible for building a swimming pool for the imperial palace. After all, only he had built this new thing.
"How beautiful?" Princess Changle was immediately attracted by the beautiful scenery in the painting.
"Beach, sea, it''s just like visiting the sea?" whispered the eldest Sun Queen,
"The sea?" Princess Changle suddenly brightened her eyes and fell into reverie.
The most important reason why the style of swimming pool is so high in future generations is to give people a feeling of being in the sea.
The longer you stay in the deep palace, the more you yearn for freedom. The sea is the most vast and free representative. Princess Changle can''t help but become more and more interested in the swimming pool in the painting.
In the hot summer, on the weeping willows held by one beside the Taiye pool, several cicadas who escaped the pursuit of eunuchs kept singing, adding a bit of irritability to the hot weather.
In front of a side hall next to the Taiye pool,
Merton is sweating and directing the hard work of a group of craftsmen. Although the efficiency has been improved ten times with the help of Mohist machinery, the amount of swimming pool built by Merton for the imperial palace is much larger than that in the backyard of the Mohist house.
"The adult area should be more than one foot deep, and the children''s area must not be more than three feet deep. At the diving platform, the water depth is two feet, and the track should be more than 50 steps." Merton explained his requirements to the craftsman who will be sent by the supervisor.
Of course, it is not the children of Mohism who are responsible for the construction, but the craftsmen who will be sent by the supervisor. The first is a middle-aged craftsman who is extremely skilled and can only compare with Lao Zhang tou and others in Mohist village.
"Lord Hou, don''t worry, it won''t delay the construction period." the middle-aged will be a big craftsman, and promised with sweat. In his opinion, the construction of this swimming pool is the simplest thing. Although the quantities are larger, the completion of the construction is only a matter of time, and there is no technical content in itself.
Merton inspected again and found that everything was working normally. Then he returned to the next pavilion under the weeping willow. He found that his drawings on the stone table of the pavilion had already disappeared. Then he remembered Li Zhi''s sneaky action just now. He must have taken it away.
"My brother is naughty. Please forgive me for taking away master Mo''s drawing!" a voice as light as an Oriole sounded behind Merton.
