The demise of the Sui Dynasty was an irreconcilable contradiction between the ruling class scholars and emperors, and eventually fell apart.

In fact, the Ming Dynasty was similar, and it was also an irreconcilable conflict between the literati and the emperor, which eventually came down to "silver". Chen Ying twisted the pages of the manuscript and was distracted under the lamp.

The 800-mile fertile soil in Guanzhong seemed to have a lot of arable land. However, with the increase of the population, especially the crazy annexation of land by aristocratic families and powerful people, the Tang Dynasty eventually lost the credibility of the country and led to the Anshi Rebellion. In the fifth year of Daye of the Sui Dynasty, the population in Guanzhong reached 3.07 million (according to the 16th issue of "Tang History and Theory", edited by Du Wenyu, a doctoral supervisor of the Sui and Tang Dynasties of Shaanxi Normal University, the data is the same below). However, by the 13th year of Zhenguan, the population in Guanzhong was only 1.43 million. However, this 1.43 million population needed to transport 200,000 stones of grain from Guanzhong every year. By the first year of Tianbao, the population in Guanzhong increased to 3.21 million. However, the food gap in Guanzhong reached 4 million stones in the third year of Tianbao. New Tang Books and Foods Records.

Chen Ying naturally discovered a very funny problem. The arable land in Guanzhong exceeded 400,000 in the Tang Dynasty. In the Tang Dynasty, one acre was 581 square meters and one acre was 100 acres, which can be said to be 40 million acres. Assuming the number of people was 4 million, each of them had ten acres of arable land. With the yield of acres at this time, it was not a problem to maintain normal consumption. However, in the Tang Dynasty, it turned out to be a great famine in Guanzhong and Shandong helped.

The most intuitive reason is actually not difficult to guess. A large amount of land has been brought to the hands of aristocratic families and nobles, and they do not have to pay taxes. The court's taxes have decreased and they have to transfer grain to the capital. What's even more tragic is that Guanzhong is the foundation of the Tang Dynasty. Because the court did not have enough land to accommodate the government soldiers, the government system established by the Western Wei Dynasty completely collapsed during the Tianbao period.

In later generations, it was only 1.51 million in Guanzhong, which was only about 260,000 in total, about two-thirds of that in the Tang Dynasty. However, the grain output in later generations was 9.32 million tons, feeding more than 20 million people in Guanzhong, but there was no pressure. Chen Ying thought secretly that even if the grain production capacity was only half of the later generations, feeding the population of Guanzhong would not be a problem.

If Chen Ying was asked to increase the grain yield to a thousand kilograms per mu, Chen Ying was not sure. After all, the efficacy of fertilizers is well known. If Chen Ying could produce more than five stones per mu of fertile land, it would be okay to feed tens of millions of people with the scale of land in Guanzhong in the Tang Dynasty.

Li Xiuning looked at Chen Ying and couldn't help but ask, "Chen Lang, what are you thinking about, Chen Lang?"

Chen Ying shook his head and said, "Nothing!"

Li Xiuning showed that she didn't believe it at all, and turned her head away.

Chen Ying had to smile bitterly and said, "I was thinking that the difference in production models determines the fundamental gap in the base of population and the ability of military organizations that can be raised on the same land."

Postmodern words made Li Xiuning confused, like clouds and mountains and mists. Li Xiuning asked in confusion: "What is the direct relationship between this and your book review?"

Chen Ying secretly sighed that he was really a mediocre person.

You have to eat rice one bite at a time, and you have to take the road step by step, and you can't take too much steps. If it's too big, it's easy to get involved. For example, Wang Mang and Yang Guang, these two big brothers have played themselves in because of their big steps in reform.

Chen Ying smiled bitterly and didn't have time to speak.

Li Xiuning threw the book on the table, stood up and said to Cui'er, "It seems that some people are not happy that we are here... Let's not be upset here, pack up and go home." As he said that, Cui'er was confused again, blinked.

Cui'er finally failed to waste Li Xiuning's kindness for a long time and understood Li Xiuning's meaning: "Your Highness, I will pack up now."

As he said that, Li Xiuning and Cui'er walked out the door together.

Although Chen Ying is not Chu Ge, he really lacks experience in dealing with women. If he is a love expert in later generations, Li Xiuning can play with Chen Ying at a glance.

However, Chen Ying didn't see it. He thought Li Xiuning was really angry, so he hurriedly stepped forward to stop Li Xiuning and said anxiously: "Sanniang, I didn't refuse to welcome you. If you can come to me... I... am very happy."

Chen Yingyi became nervous and couldn't speak smoothly.

Li Xiuning looked at Chen Ying who was so arrogant on the battlefield. At this time, he was speechless and uneasy, and felt very comfortable: "What do you mean? I've come, and you don't accompany me everywhere? Could it be that you are hiding a charm in the golden house?"

"Where is it?" Chen Yingwang looked at the dark night sky outside and asked hesitantly: "Just now?"

"Now, is there anything wrong?" Li Xiuning turned around and looked at Chen Ying and said, "We can learn from the ancients!"

"Learn from the ancients?" Chen Ying thought to himself, why are you learning from the ancients? You are the ancients.

Seeing that Chen Ying had not understood what Chen Ying meant, Li Xiuning covered her mouth and chuckled, "Learn from the ancients... to travel at night with candles."

"Okay, let's go now!" As he said that, Chen Ying shouted outside the door: "Lan'er, bring a few lanterns!"

After a while, Lan'er was carrying a lantern, and the Luzhu and Hongxiu sisters were also carrying a lantern. Chen Ying pointed to the three large rooms in the left side of the study and said, "This is my bedroom. Do you want to go in and take a look?"

Li Xiuning didn't say anything and walked straight towards Chen Ying's bedroom.

Lan'er and Hongxiu walked quickly in front, lit the door of Chen Ying's bedroom, and lit the candlesticks in the house one by one.

Although Chen Ying's bedroom has three houses, in fact there is only one real bedroom, one is an indoor bathroom, and the other is the ear room where Lan'er's maid lives. There are lion-head copper lamps on both sides of the bedroom, which are shaped like hydrangeas from the heads of lion dancers in later generations. Each embroidery bead has a lamp plate, which contains five lamp posts, four twenty lamp posts, and three large candles are lit at the same time, making the three bedrooms bright as day.

Chen Ying’s big bed is also completely different from this era.

It is a large Simmons bed with a backrest, but it is just a larger scale. The entire bed is 1 meter wide (about 2 meter three 5) and 9 feet and 6 inches long.

Li Xiuning looked at Chen Ying's bed, suddenly turned around and said with a smile: "This bed may have slept with many people!"

Lan'er spoke quickly and said without hesitation: "There is no rush to sleep at all for four people."

Chen Ying's face turned green when he heard this.

Li Xiuning's face slowly changed.

Four people.

Aren’t Lan'er, Hongxiu, Luzhu and Chen Yingke just four people?

Li Xiuning looked at Chen Ying fiercely: "Chen Langjun, you really know how to enjoy it. Why don't you build a bed that is ten feet wide?"

Li Xiuning said to Cui'er with a stern face: "Let's go!"

Chen Ying knew that Li Xiuning had misunderstood when he heard this. He said to Lan'er with a treacherous face: "When did four people sleep in this bed?"

When Lan'er saw Chen Ying's fierceness, tears came out: "It was last month, when Gao Wenjin came, the four of us slept on it, which was very comfortable."

Li Xiuning blushed and knew that she had misunderstood.

Chen Ying pointed at Li Xiuning to visit his bathroom.

Fortunately, Li Xiuning was attracted by Chen Ying's strange bathroom.

...

After coming out of Chen Ying's bedroom, Chen Ying took Li Xiuning to the corner building in the front yard.

The Corner Tower is where Chen Ying first built a simple looking tower. At this time, a seven-story octagonal building rose from the ground. Chen Ying and Li Xiuning walked to the seventh floor of the Corner Tower. Chen Ying pointed to the outline of the Chen family fort in the distance and said, "This will be our future home. Although the place is not big... it can protect you from the wind and rain."

Li Xiuning said in a little surprised: "Chen's fortress is over 200 feet long, right?"

Chen Ying nodded and said, "It's more than 272 meters tall, two feet tall, and the city wall is one or two feet thick."

It is long, that is, the circumference means 272 zhang, about 6,392 meters, which is already a considerable city.

Chen Ying continued to explain to Li Xiuning: "The city wall is made of blue bricks and earth-shaping. On the outside of the solid and tall brick and stone wall, another low earth wall is built on the east and west sides of the east and north sides. A narrow space is left between the earth wall and the wall. It is also a patrol road for the updater to pass."
