It was close to noon, and Li Ke, who had experienced many things today, felt tired even if his body was strengthened. Pen ~ fun ~ pavilion www.biquge.info

Fortunately, the mountain road in Ersanli is not far away, and after a while, the sound of flowing water came from afar, and Li Ke heard the gurgling sound of the flowing water and cheered up, after all, the sound of the water has been heard, will the flowing water be far away?

After a while, I saw a wisp of clear spring pouring out of the stone gap in the distant mountain stream, and a pool of water was just around the corner. There are ruts printed on the edge of the pond, and it is thought that it was also left by the palace people who took water.

Li Ke saw that there were no weeds on the edge of this waterhole, and there were no snakes, rats, insects and ants to make trouble, so he also nodded. It's just that in the middle of winter, the surrounding vegetation is almost withered and withered, and I can't see what the summer is like here.

Seeing someone coming here, a young palace man who was on duty came out of a thatched hut in the distance, and when he saw the person who came, he was dressed in fresh clothes and angry horses, and the soldiers guarded the road, and he was busy coming out to greet him.

"The slave maid Zhang Rang didn't know that His Royal Highness King Wu had arrived, and he was disappointed, so he really deserved to die." Someone came forward and saluted like Li Ke.

"Get up, is this your duty lately?" Li Ke saw that there was a built thatched house here, and there were people who took care of it for a long time when he wanted to come to this place to get water.

"The slave maid is a palace person who was sent here by the palace yesterday, and there is also a companion who came with him, and it is about noon, but he went to get food, I don't know what His Highness is here for?" The palace man said solemnly.

"Lone came here to verify the quality of the water at this water intake, can this waterhole have a name? What kind of trees are the trees around the waterhole? Li Ke saw that the trees around him had lost their leaves, leaving only bare trunks, and he couldn't distinguish the species, so he asked casually.

"This place is called Peach Blossom Pond, surrounded by peach trees, when the spring is shining, the peach blossoms bloom along the stream, like a paradise." The little eunuch Zhang faced Li Ke and told Li Ke the origin of this waterhole, and it could be seen that this little eunuch was also a person who had read a few books, and he also knew Tao Yuanming's peach blossom source.

After talking about the allusion, Li Ke wanted to chant a sentence: "The Peach Blossom Lake is a thousand feet deep, and it is not as deep as Wang Lun to send me love." "That's it. Wait, Peachtree? Peach blossom! Li Ke's eyes instantly turned cold.

"Who found this place as a place to draw water?" Li Ke frowned and said coldly.

Gonggong Zhang was so frightened that his legs trembled, and he didn't understand why Li Ke suddenly turned his face, so he threw himself on the ground and kowtowed: "Your Highness, the slave maid doesn't know, this is the place where the Furong Imperial Garden has always taken water, and the slave and maid are only dispatched here to perform their duties here." ”

"So you don't know if this is the place chosen by the Shangshi Bureau to get water?" Li Ke scolded.

"This slave and maid really don't know, the slave and maid only know that since the founding of the Tang Dynasty, the Furong Imperial Garden has been taking water here, Your Highness, look over there, this peach forest and the wasteland next to the thatched house are also left by the former Sui." Father-in-law Zhang threw himself on the ground with a panicked face.

Li Ke couldn't ask the little eunuch again, so he had to continue to look around, only to see that the peach trees everywhere were not like recently planted, it seems that this place may indeed be left by the former Sui, if the peach blossoms are in full bloom in spring, the fragrant grass is delicious, the petals are falling, and the falling flowers are colorful but it is also an excellent artistic conception.

It's just that Li Ke suddenly remembered that the peach tree is very prone to insects during the flowering period, because the branches and leaves drawn out of the peach tree in spring have nectar glands, which are easy to provoke mosquitoes, and the peach tree is also a tree that is very prone to insects. In later generations, people often said that they committed peach blossoms, which actually means that some people are very easy to provoke some bad marriages.

If you take water when the peach blossoms are in full bloom, the water quality is definitely not much better because of mosquitoes, and the peach blossoms bloom at the water's edge and the petals are scattered in the water. But Li Kecai from the day of Yuan Zheng, the little son was sick because of pollen allergies, and now he is extremely sensitive when he sees words with flowers, so he can't help but reprimand the palace people who are on duty.

Li Ke couldn't help but be glad that he came here for a trip, if he didn't come in person, if he really waited until the peach blossoms were in full bloom, Li Ke estimated that he would have to say goodbye to Chang'an, it seems that even if he crosses over, he can't take it lightly.

"Your Highness, have you noticed something wrong?" Yuan Kui saw that Li Ke was angry, and stepped forward to persuade, after all, in his opinion, this is just a very normal place to get water, but why is His Royal Highness angry for no reason?

"Yuan Kui, tomorrow you send someone to take this piece, forget it." Li Ke originally wanted to cut down all the peach forests and plant trees that do not bloom, such as green pines and cypresses, so as to prevent pollen from entering the water. But when I think about it, I feel that my thoughts are too much of a headache and a pain in the feet, which is simply a symptom but not a root cause.

Speaking of treating the symptoms but not the root cause, Li Ke couldn't help but think of a friend who was also a researcher in his previous life, and recently said that Lao Mei's thinking is called treating the symptoms but not the root cause, such as what to do when the weather is hot? So I used an air conditioner to cool down. What to do if there is too much rain in the city and floods? So more drainage ditches were built. What should I do if I can't tolerate the rain in the gutter? Drain into the river. What to do if a river is polluted? Construction of sewage treatment plants. What if the river can't tolerate flooding? Build dams. In the end, there are a lot of completely unnecessary constructions, but they still do not solve the problem, but make the problem worse.

Unfortunately, the urban planners of the Celestial Dynasty in later generations also learned the old American method of treating the symptoms to build China, and adopted the Western construction concept and design techniques, which led to the previous Li Ke before he left, and some residents could still see the posts of "looking at the sea in the city". Li Ke didn't want to cut down all the peach trees to treat the symptoms now, and then cause a new incident, and finally pressed the gourd and scooped it again, so he had to think hard to find a way.

After a while, Li Ke saw that there was a bamboo forest in the distance, and he couldn't help but think of a way in his heart.

"Akui, early tomorrow morning, you will take the craftsman from the spring to draw a stream of spring water from the bamboo, and tell the palace people who take the water not to take any more water from the pool. I'll give you the pattern when I go back. Li Ke said lightly. I plan to go back and draw a diagram of a screw water dispenser, and take water directly from the spring of this mountain stream through the thread principle, which can avoid the water being polluted by the peach forest, and can also use the height difference to make it easy to take water.

The problem of taking water is solved, and the rest is the problem of clean water, after all, there is no tap water treatment plant in this era, and there is no clean activated carbon, whether it is the common people or the princes and ministers are drinking unpurified natural water, but there are nobles drinking spring water, and civilians drinking well water.

Li Ke's main purpose in coming to this waterhole is actually to try to see if the water purification method in his memory has any effect.

"Who's that。。。。。 Belch... Li Ke called out to the palace man surnamed Zhang, who was on the ground, "You go and get a bucket of clean water." ”

"Yes." Zhang asked his father-in-law to get up immediately, and went to the edge of the pool to fetch a bucket of water.

Li Ke saw that the water was clear and sweet, not as turbid as the river water he had seen by the city wall just now, but he was still a little uneasy about this water, so he prepared to make a more primitive water purifier - cactus water purifier to purify this bucket of water.

Li Ke took out a piece of cactus picked in the palace in his sleeve, gently scraped the skin of the cactus with a knife, and then used a piece of bamboo to split it into bamboo pieces, clamped the cactus with the scratched skin and put it in the water to stir.

Everyone stared at what Li Ke had done, only to see that the water in the bucket was stirred at a constant speed by Li Ke, and the originally clear water seemed to be surging like a trick, constantly precipitating something, and finally a layer of gray things was deposited at the bottom of the bucket.
