After Yun Needle joined the team, only one day later, everyone arrived at Sanmenxia. abandoned the ship and landed ashore, and soon arrived at the famous Tongguan.

When passing through Tongguan, when I saw the cloud needle of Tongguan for the first time, I couldn't help but be shocked by the majesty and enormity of Tongguan, but Lu Zhe didn't care, when he learned that Lu Zhe was coming for the first time, even if it was Yuwenyin, he had to secretly praise.

This little demon is good at cultivating qi kung fu!

In fact, even Yu Wenyin, who grew up in the imperial capital and saw a lot of gorgeous buildings, when he saw this Xiongguan for the first time, he was also shocked by this tall and heavy Xiongguan, which made most of the soldiers and horses in the world helpless. However, this Shanshui Lang is only eleven or twelve years old, and it is the first time he has seen this Tongguan, but he has no expression of surprise and shock at all, and even has a faint bored look. This little demon is really not very human, obviously shocked like something, but on the surface he can't see it at all.

After a series of previous incidents, the above evaluation can be regarded as the most positive evaluation made by Yu Wenyin to the ruthless and treacherous Shanshui Lang of his mind.

In fact, Yu Wenyin was wrong, Lu Zhe was not good at qi cultivation, but he really felt a little bored. Although in his cognition, how can people who see Tongguan for the first time not be shocked by its tall and majestic, if not, they must be pretending.

For Lu Zhe, who has seen buildings of several hundred meters in later generations and lives in a forest of high-rise buildings, the Tongguan in front of him is too small and broken.

Lu Zhe looked at those crossings in his previous life, and every time those predecessors crossed back, passing by Tongguan or some famous building, he was always shocked and speechless, and sighed at the magic of the ancients.

As a result, when he really crossed back, he saw Tongguan and found that it was smaller and more dilapidated than what he saw when he traveled in later generations, and his heart didn't even fluctuate at all.

However, when he passed through Tongguan and walked towards Weinan, he was shocked.

"The peaks are like gathering, and the waves are like fury. Mountains and rivers surface Tongguan Road. Lu Zhe chanted faintly.

And everyone is no longer surprised that Lu Zhe has a few strange words from time to time. Although the sentence is strange, but after chewing it carefully, I feel quite fresh and cute, intriguing, and even very brainwashing.

For example, a few days ago, this Xiao Langjun sang the song "A Laugh in the Sea" in a strange tone, although the tone was strange and strange, but it was better than being plain, only half a day, even the boatman on the boat hummed the ups and downs with the waves. (PS: Everyone found that no, they are used to singing in Mandarin, and some songs let you sing in dialects, which is quite difficult).

"Hey......" Riding a little green donkey, looking at the scenery near Tongguan, Lu Zhe couldn't help but sigh. This hillside goat, the second half of the Que has never been pronounced.

"Lucid waters and lush mountains are invaluable assets." Lu Zhe looked at the farmers burning on the high slopes of the loess along the way, and suddenly felt that his nose was a little sour.

At this time, the Loess Plateau, there are already some signs of soil erosion, the Yellow River was very clear in ancient times, it was called the big river, and now it is the Yellow River, the desertification of the Loess Plateau has also begun to be highlighted, and the farmers of Tongguan have to work day and night.

Looking at the farmers on both sides of the road, who are burdened like beasts and work non-stop. Lu Zhe couldn't help but sigh a little.

In the feudal era, the peasants of our country have always undertaken the hardest work, the heaviest taxes, and the group of people who occupy the least social resources, and their needs are also very simple.

In this era of extremely low production efficiency, the Tang farmers, who had borne the heaviest taxes, in order not to starve to death, could only cultivate as many fields as possible and win by quantity, and a large number of burning mountains to open up wasteland, resulting in soil erosion, barren fields, and even more insufficient food grown on the ground.

Prosperity, the people suffer, death, the people suffer. The whole feudal era was nothing more than that.

But what can they do, you go and tell these peasants who barely starve to death in good years, and sell their sons and daughters in famine years, the importance of preserving water and soil? For farmers who have been working hard to feed all their lives, they can't understand it, and they can't understand it.

"Hey......" Lu Zhe turned his head to look at the carriage behind him, and in the wooden box inside, there was a model of the Quyuan plough he made. I secretly made up my mind in my heart, even if it was for the sake of these farmers who were like facing the loess with their backs to the sky, and a drop of sweat fell eight petals. It is also necessary to promote agricultural techniques such as curved ploughs and fertilization and deep ploughing in the world. One day, after I have some say in this world, I will definitely promote the benefits of soil and water conservation for the benefit of future generations.

Although I don't know much, even a little bit may bring a lot of changes to this era.

It can be regarded as his greatest kindness to this era and these simple and hard-working old farmers.

After passing the Tong Pass, the group soon arrived in Weinan.

And after arriving in Weinan, Chang'an is not far away.

So, on a sunset afternoon, in the willow catkins in the sky, Lu Zhe rode a little green donkey, slowly passed by the Baqiao, and finally saw the city wall of Chang'an.

The ancient city wall of Xi'an, which once amazed Lu Zhe in later generations, was built in the Ming Dynasty, and the Chang'an city wall at this time, although it looked not as tall as the Ming city wall, but the Tang city wall, which was close to three zhang, did not have the ancient desolation of later generations, the huge and brand-new bluestone, and the guards in shining armor at the city gate, but revealed a vitality.

It's the capital of a huge newborn empire. Looking at the flow of people coming in and out, Lu Zhe couldn't help but feel a little in a trance, as if he had returned to the imperial capital of later generations.

The people of the Great Sui Dynasty said that Luoyang City was the greatest city in ancient times; But the people of the Tang Dynasty also said that Chang'an was the greatest city in ancient times; The people of the Song Dynasty said that Bianliang was the greatest city in ancient times; So it's hard to figure out exactly where the greatest city of all time is.

But Chang'an, in ancient Chinese history, should be considered one of the greatest contenders for the greatest city.

Because, in later generations, the strong Han and Sheng Tang that the Chinese talked about, the capital was Chang'an.

As the imperial capital of several dynasties, Chang'an is known as the capital of 'the spine of the world and the first dragon of the Central Plains'. Surrounded by mountains and rivers, it is located in a thousand miles of fertile fields, there are Huashan Mountain in the south of Chang'an, Zhongnan Mountain, Taibai Mountain in the west and the Hengling Mountains behind it, it is in the Guanzhong Plain, it is easy to defend and difficult to attack, and it has always been a place where soldiers must fight. In addition, the eight rivers of Wei, Jing, Feng, Li, Wei, Zhu, Chan and Ba surround it, so that the Guanzhong Plain is known as a fertile field for thousands of miles, and the history is called 'eight rivers around Chang'an'.

The capital city is a large country, and the eight rivers flow around the four mountains. How many emperors prospered here, and the world said Chang'an in ancient times.
