Otaku Engineer in Great Tang Dynasty Chapter 1297: On the importance of planting trees! (Next)
In the Temple of Ganlu.
Just when Li Zexuan was so bored waiting to find a place to sit and rest for a while, there was a sound of footsteps outside the hall.
Li Zexuan's expression was solemn, and he quickly "stands" in the hall.
"Hehe! Your kid must be impatient, right?"
Sure enough, the person here was Li Er, and the old Li Long walked into the hall step by step, and when he walked beside Li Zexuan, he said with a smile.
Although Li Zexuan had this idea in his heart, he was not stupid enough to say it. Hearing that he quickly handed over: "Your Majesty summons the minister to the palace, there must be something important to tell, the minister is in good spirits this time. How can you be impatient when you are ready to listen to the Hadith~?"
"Hehe! You kid!"
Li Er pointed at Li Zexuan, smiled irritably, and then raised his foot to the seat above.
At this time, a servant came to report: "Your Majesty, Zhao Guogong, Fang Xiang, Du Xiang, Xiao Shangshu, Yan Shangshu are waiting to see you outside the hall!"
"Proclaim!"
Li Er sat on the couch and said solemnly.
After a while, several important imperial officials walked in. They were a little surprised that Li Zexuan was also in the hall, Changsun Wuji and others.
Following the courtesy, Li Erchong and Zhao Song nodded in greeting. The latter took out five pamphlets and distributed a copy to each of the five ministers. Li Er said at this time:
"Everyone, Aiqing, this is the fold that Li Zexuan submitted yesterday. I asked someone to transcribe five points. Please take a look first. After reading it, I will ask questions!"
"No~!"
The five important ministers promised one after another, and then they all looked at Li Zexuan imperceptibly, and they were probably secretly saying in their hearts: Sure enough, where there is Li Zexuan, there is right and wrong!
When everyone bowed their heads and saw the first few sentences of Li Zexuan's memorial, a sense of absurdity arose in their hearts. If it were not for the wrong occasion, it is estimated that they would be the same as Li Er at the beginning of last night. They laughed aloud, but soon their faces became serious.
Time passed bit by bit, and there was no sound in the hall. Li Zexuan held his hands and stood silently in the hall, secretly guessing in his heart that these veterans would ask him some difficult questions for a while.
"Huh? Have you finished reading it? Do you have any objections to what Yong'an Hou played on the Zhezi?"
About a quarter of an hour later, Li Er's voice sounded in the hall.
The five ministers first looked at each other, then Fang Xuanling stepped forward and said: "Your Majesty, the old minister has a few questions to ask Yonganhou, I wonder if you can?"
Li Er waved his hand and said: "You don't have to be restrained. If you have any questions you want to ask Yonganhou, just ask, if you can answer Yonganhou, please answer!"
"The ministers wait for the order!"
All the ministers under the hall clashed their hands.
Fang Xuanling looked at Li Zexuan at this time and asked: "Dare to ask Yonganhou, you said the water quality of the Yellow River was clear before the Qin and Han dynasties, do you have evidence~?"
Li Zexuan stepped forward and replied: "Of course there is evidence! The juniors and the gentlemen of the academy have looked through the history of previous dynasties and found that the previous record of "Heqing" began in the late Eastern Han Dynasty, indicating that it was before the Eastern Han Dynasty. Relatively speaking, the Heqing phenomenon may be more familiar and not a strange event, so it has not been recorded! Since the Eastern Han Dynasty, the sand content of the Yellow River has increased and the turbidity has become worse, so "Heqing" has become the auspiciousness of the country, and the writing is in history!"
Fang Xuanling contemplated for a moment, then slightly nodded: "Hou Yongan said in the memorial that if the Yellow River is allowed to increase in sediment, the eight waters of Chang'an will become muddy in less than 20 years?" /
Li Zexuan said: "About this point, I believe that the younger generation should not say it, the picture must be clearer than me? In the previous period, what was the water quality around Chang'an City? What is it like now? Careful!"
He has only been here for a year, so naturally he doesn't know the situation in the former Sui Dynasty, but Li Gang knows! According to Li Gang, the water quality around Chang'an City is indeed inferior to the previous ones!
Fang Xuanling, Changsun Wuji and others looked at each other, and finally sighed, apparently acquiescing to this fact.
Li Zexuan added: "The quality of water is related to the lives of millions of people inside and outside Chang'an City. The cholera outbreak in Chang'an City last year has nothing to do with the presence or absence of yellow sand in the river, but it is also because the water quality has been affected. Cholera is caused by pollution! The land we are now in is soft. When there is a strong wind, the yellow sand will be filled. When there is a heavy rain, the loess will flow into the river. In the long run, the sediment content in the Yellow River is bound to increase. , The water can't bear the consequences!"
Everyone's complexion changed. After all, the cholera in Chang'an city last year is still vividly visible!
Fang Xuanling paused for a while, and asked again after a long while: "Hou Yongan, you said that the increase in sediment content in the Yellow River will easily cause the river bed to be too high in the lower reaches. A heavy rain will cause the Yellow River to burst. This matter~?"
Li Zexuan smiled slightly and said: "This is natural! Yan Shangshu is good at engineering and manufacturing, he must know this better than me! If Fang Xiang doesn't believe in juniors, you can ask Yan Shangshu!"
Without waiting for Fang Xuanling’s question, Yan Lide nodded and said: “Yes! If the Yellow River sediment is allowed to accumulate, the sediment will be deposited in the shallower part of the downstream water flow. The river bed will definitely be too high. It’s not a problem to raise one foot high! If there are continuous heavy rains, the lower Yellow River will surely burst! By then, thousands of people will suffer!"
In fact, Yan Lide's prediction is still optimistic. In modern times, the water level of the Yellow River is more than 70 meters higher than that of Kaifeng, and it has become a veritable hanging river above the ground!
Xiao Yu asked in a deep voice: "Hou Yongan, what do you mean is that if the court does not adopt your tree planting measures, the floods in the lower Yellow River will become more and more serious in the future~?"
Li Zexuan nodded:
"In the past few days~IndoMTL.com~Mr. Li Gang and I read the local county chronicles of the lower reaches of the Yellow River in previous dynasties. It is well documented that from the Eastern Zhou Dynasty to the end of the Eastern Han Dynasty for more than 800 years, the lower reaches of the Yellow River There have been only twenty burst floods in total, with an average of one flood every 41 years;
In the four hundred years from the Three Kingdoms to the former Sui Dynasty, there have been 23 floods in the lower reaches of the Yellow River, an average of once every 17 years! If we do not take measures now, the Yellow River will burst more and more frequently in the future, and even burst every three years! At that time, the money spent by the court on flood control and relief of the people would far exceed the money spent on planting trees now! "
Speaking with data, speaking with facts, this is what Li Zexuan, an engineering expert, is best at and also likes most. After these words, the faces of everyone in the hall became serious.
And Li Zexuan's next sentence is even more shocking, "Before my master died, he not only predicted this year's locust plague, but also predicted that in nine years, the Yellow River will break its **** again, and Luoyang City will be completely destroyed. Flooded, the creatures are charcoal!!"
