Li Kang hurriedly pulled his son to kneel, shouting long live! Li Kang didn't expect that this toilet case would attract the emperor, let alone that the noble person he met that day was the current emperor!

Emperor Lizong said with a smile: "The two Qing families are even!" I didn't expect to come to Dali Temple today, but I watched a good show! But the flush toilet you made is a good thing! It's the first time I've done anything like this, and it looks like I'm not wrong! ”

Li Kang hurriedly said: "The emperor has praised it!" This thing is the idea that the dog came up with when he went to the toilet, and the design drawings were also made by him, this thing can make people go to the toilet more comfortably, so I also asked the emperor to approve it, and it was made in large quantities in the official kiln of the Xiu Nai Division for the renovation of the toilet in the palace! ”

Emperor Lizong laughed and said, "Of course, this thing not only has to be made, but also in large quantities!" Not only can it be used in the palace, but it can also be used by the people! By the way, Li Xiang Aiqing, how did you come up with the idea of designing such a thing? I'm curious! ”

Only then did Li Xiang realize that the emperor's cloudy eyes suddenly flashed with a glimmer of light, and he was staring at him without blinking. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Sure enough, it is the Son of Heaven, different from ordinary people, the spirit of the king on his body is fully revealed, no wonder ordinary people are so frightened that their legs and feet do not obey the call when facing the emperor, it turns out that the legend is not fake. Because the emperor can decide the life and death of an ordinary person with one sentence, that is, the so-called world is big, it is not the king's land, the shore of the land, it is not the king's minister, the world is the emperor's, so the emperor can naturally decide a person's life and death.

Li Xiang calmed down his excitement for a while, and then said slowly: "Your Majesty, the grass people also thought of such a thing because of the inspiration of going to the toilet, because they felt that the toilet was too smelly at that time, so they thought if they could make a toilet that could not only sit comfortably on the toilet, but also block the feces, so this flush toilet can just do this." Of course, the grass people think that this can be regarded as a revolution in the toilet, not only this flush toilet, but also to design the toilet system, when the toilet is not only hygienic and convenient, but also can use feces to collect and produce a new fuel, called biogas, which can be used to cook rice and vegetables, can also be used to burn ceramics, instead of firewood, become both convenient and clean! ”

"What? Can this manure be used as fuel? Is this true? It's incredible! Emperor Lizong's eyes widened, he looked at Li Xiang and muttered, "Tell me quickly, what the hell is going on!" ”

Li Kang also wondered, his son had never told him this, so he became curious.

Li Xiang sorted out his thoughts for a while, and then said: "Your Majesty, you must have heard of the Tao too!" Doesn't the Taoists say that the Tao is in everything, even in the dunghill? This is one of the functions of the manure pit. The grass people found a very special phenomenon, especially in the summer and autumn when the temperature is high, you can often see that from the stagnant ponds, sewage ditches, and manure tanks, many small gas pools emerge to the surface, and then the grass people collect these small bubbles and light them with fire, which can produce blue flames, and this gas that can be burned is biogas. ”

Emperor Lizong said excitedly: "But if there is such a thing, why have I never heard of it!" ”

Li Xiangzheng said: "Your Majesty, how can anyone tell you about this kind of thing?" Moreover, although they generally saw it, they did not study the cause of this phenomenon, and no one experimented with collecting these filthy gases. Biogas is essentially a convenient, clean, high-quality, high-grade gaseous fuel produced by fermentation of human and animal manure, domestic sewage and plant stems and leaves under certain moisture, temperature and lack of air conditions, which can be directly cooked, heated, dried and stored grain. Of course, the grass people also thought of using it to burn porcelain, so that there would not be so much labor to chop wood, and more importantly, using this biogas to fire porcelain, the grass people thought that the yield would be greatly improved! ”

At this time, in Li Xiang's body, the super 3D printer appeared again, and a huge three-dimensional picture of the biogas digester appeared in his mind, of course, others could not see it, and this super 3D printer prompted whether it was necessary to print an industrialized biogas digester!

Li Xiang hurriedly said with consciousness that he didn't need it, and at this time, the super 3D printer showed the history of the development of the biogas digester! Fortunately, no one in this day and age knows what biogas is!

According to the data, until 1776, Italian physicists measured methane in the gas produced by the decay of plants at the bottom of the lake, but no one knew how it was produced at that time. In 1896, a biogas digester was built in a small city in Britain to treat the sludge produced by domestic sewage, which can be used to light a street. In 1967, Bryant isolated and purified hydrogen-producing, acetic acid-producing bacteria and methanogens in biogas fermentation microorganisms, and people began to have a correct understanding of the microbiological principle of biogas fermentation.

Emperor Lizong stood up excitedly and said loudly: "Two Aiqing, what you said is true? If that's the case, then this biogas is a treasure! There is also this toilet revolution, I also want to vigorously support it, no, I want the people of the Great Song Dynasty to use this kind of flush toilet, and also use biogas for cooking! This, this is really good! ”

Li Xiang hurriedly said: "Congratulations to the emperor!" With this flush toilet, clean toilet and biogas, I believe that it will not only benefit the country and the people, but also show the advanced culture of our Great Song Dynasty, so that everyone in the world will yearn for the prosperity of our Great Song Dynasty! ”

Emperor Lizong stroked his beard and smiled: "Okay! This toilet revolution is really wonderful, if it is really as you said, even the face of the palace has also changed. Now the palace is composed of the inner servants of the pure army and the like, every day to push the clean car, clean the pit toilet, the palace clean car is built once every 5 years, up to hundreds, the annual expenditure for the toilet is thousands of taels of silver. With the toilet you designed, not only can you turn this waste into treasure, but you can also save money on firewood! ”

Li Kang hurriedly said: "The emperor is sage! ”

Emperor Lizong nodded and said: "In this case, I will order your father and son to be fully responsible for this toilet revolution, but Li Xiang Aiqing is still in the Guozijian and has not achieved fame, so he will not be awarded an official for the time being. ”

When Li Kang heard the emperor personally say that he was promoted to an official, he knew that he really borrowed his son's light this time, this young eunuch is at least a sixth-rank official, but it is a few levels higher than his current eighth-rank official, so it is not easy to find a few promotions in a row! However, the toilet revolution is indeed a huge project, and if it is not done well, it may also make the emperor dissatisfied, so this is both a happy event and a feeling of pressure!
