Otaku Engineer in Great Tang Dynasty

Arbor Day~? Oh~! Guanyin maid, do you think this kid has nothing to do all day long? Want to plant trees? "

In the evening two days later, in the Ganlu Hall, when Li Er was reviewing the memorials, he saw a wonderful memorial and couldn't help but smile at the grandson empress who accompanied him to review the memorials.

At this time, Li Zexuan spent a whole day compiling a memorial suggesting that Li Er should promote the tree-planting festival and advocate the people of all states and counties in the Yellow River basin to build shelter forests. During the period, he went to the library of Yanhuang Academy to check whether Few ancient books.

Oh, it’s worth mentioning that since the library of Yanhuang Academy, Li Gang has been committed to expanding its books since the day it was built. Many princes and nobles can’t get it. Old gentlemen can get them and hand them over. After rubbing at the printing department of the workshop, send it to the red building of the college to expand the library! Today, the library of Yanhuang Academy can be regarded as the second largest collection of books near Chang'an City!

As for the number one, it must be royal! However, according to this momentum, the library of Yanhuang Academy has more books than the royal family. Sooner or later!

But even though Li Zexuan spent a lot of effort on this memorial, Li Er’s first reaction when he saw the memorial was still a sneer. It’s no wonder that Lao Li, but through dynasties, emperors have always only cared about people’s livelihood and only their own country. , Who would care about environmental protection and planting trees?

No one in ancient China had this concept!

"Plant a tree~? Your Majesty, whose memorial is this? Could it be presented by Hou Yongan~?"

Empress Changsun asked with a smile upon hearing this.

Huizhi Lanxin, she can guess who is the owner of this wonderful memorial almost without Li Er reminding her? At present, the ministers in the court who think so freely, except Li Zexuan, I am afraid there will be no one else!

"Yeah! The maidservant Guanyin is really smart, but it was written by Li Zexuan! Huh~? This kid, it seems a bit interesting to write!"

Li Er looked and laughed, but suddenly he couldn't laugh anymore, his face was surprised.

Empress Changsun was surprised. She turned her side calmly and cast her gaze on the memorial before Li Er. Gradually, there was no more disdainful laughter in the hall. Instead, a solemn atmosphere gradually filled the hall. After a quarter of an hour, Li Er stood up, walked two steps with his hand held down, and then ordered Zhao Song in the hall:

"After tomorrow morning, Fang Xuanling, Du Ruhui, Changsun Wuji, Xiao Yu, and Yan Lide will be left for discussion, and Li Zexuan will be sent to the palace tomorrow to wait for driving~!"

Zhao Song's eyebrows trembled, and he hurriedly stepped forward and solemnly said, "The old slave follows the order~!"

……………………………

"Msang-gong, do you say that your majesty can hear what you say~?"

After dinner in Yunshan Courtyard, Han Yuxi took a cup of hot water and came to the study. Seeing Li Zexuan was reading, she couldn't help but ask.

Obviously, she has also read the contents of the envelope!

Li Zexuan raised his head and smiled and said with emotion: "Haha! Lady! There is a saying called doing everything and knowing the destiny! This is the best level that I can play with you, and I also invited Li Gang and Ma Zhou. My husband helps check. If the sage can listen to these words, it will naturally benefit future generations. If you can’t listen, I will try my best to do my part. After all, I don’t want our future children and grandchildren to have a clean mouth. I don’t have to drink any of the water~!"

This is not alarmist. According to the current development trend of Datang, it will enter a full-scale prosperous age within 20 years. At that time, the population of Chang'an is bound to continue to increase rapidly, which will bring to the ecological environment of the Loess Plateau. Under great pressure, the water of the Yellow River will become more muddy, and the eight waters will circle Chang'an. But at that time, can the current eight water veins really support the super Chang'an city at that time?

In fact, the Yellow River was not called the "Yellow" River at the beginning of ancient times, but "River". The "River" was called the "Yellow River". Because the color of the river changed, the Yellow River was named "Yellow".

The name "Yellow River" began in the Eastern Han Dynasty, but as early as the Spring and Autumn Period, there have been written records that the river was unclear. However, in the Han Dynasty, the yellow color of the river water became more noticeable, so that people called it "Yellow River".

In the middle of the Han Dynasty, the great Sima Shi Zhang Rong (zi Zhong Gong) said: "The river is heavy turbid, and the name is one stone of water but six buckets of mud." This is a phenomenon that no one has said in the early Han.

In the mid-Western Han Dynasty, Jingshui was famous for its muddy currents. In the time of Emperor Wu of the Han dynasty, "Jingshui is a stone, and its mud counts as buckets." At that time, Jingshui was used to irrigate farmland and also improved soil. The Jingshui and Weishui watersheds were the earliest areas for agricultural development in the Loess Plateau. With this development, the original vegetation was destroyed and soil erosion increased, causing the Yellow River to become more and more turbid, which became more conspicuous during the Eastern Han Dynasty. With the name of "Yellow River".

As Datang enters a state of full prosperity, this loess plateau will feed more people, and a large amount of farmland will inevitably be mined at that time. Soil erosion in the Yellow River Basin will also become more serious. Li Zexuan said that his children and grandchildren will be several years later. It is entirely possible that you cannot drink clean water!

"children and grandchildren..."

Han Yuxi's complexion suddenly became a little complicated, and she whispered: "Msang-gong, when will we have our own...children? My concubine will be sixteen years old this year!"

After that, her face was blushing.

Li Zexuan almost vomited blood, this...what he said, the focus is not here at all, right?

"Yeah~! What are you going to do, Xiang Gong? Put your concubine down!"

"Hey! Lady, don't you want children? Let's make children!"

.............

*I don’t have to mention it again~www.ltnovel.com~ Early the next morning, the young couple was having breakfast in the other courtyard, and Zhao Song came to pass the order and let Li Zexuan enter the palace and wait for driving.

Although Li Zexuan's face was calm, he still couldn't help feeling happy. After all, he was not an orthodox civil servant. He was not as experienced as Wei Zheng and Fang Xuanling when he wrote the book. Although the drafting process of this memorial was influenced by Li Gang , Ma Zhou and others’ help, but he still has no idea. Now that Li Er is willing to announce him to the palace to discuss matters, the matter has basically become a fraction!

Several people rode fast horses all the way to the imperial city, and handed Dabai to Pang Feiji to take care of them. Li Zexuan followed Zhao Song into the palace gate and headed all the way to Taiji Palace.

In the Tai Chi Hall, Li Er and Baiguan are going to the morning court. Naturally, Li Zexuan can't go in and kick in at this moment. This thing does not need to be late for class and make a "report". The early court is very formal.

Besides, Lao Li's imperial decree was to let Li Zexuan wait in the Ganlu Hall, but did not let him go to the early court.
