At night, Yuwen Wen was talking to his son Yuwen Weicheng and Yuwen Weining. Today, he and Prince Yuwen Weicheng received envoys from various countries in the South China Sea and talked about many things during the meal. Now, it is time for Yuwen Wen to answer questions.

Yuwen Weicheng, who was full of doubts, wanted to know the most was how the dynasty dealt with Linyi Kingdom. He asked: "Father, are you really not considering the former place of Sunan for the time being?"

Yuwen Wen replied: "That's not something that my father has to consider. You have to eat food one bite at a time. If you eat it too quickly, you will choke."

"However, the dynasty navy is strong, and it is no longer difficult to destroy Linyi State on a floating expedition, let alone the Nanyang Trading Company itself has a "Hong Army". After recapturing the Sunnan region, it should be no problem to quell the rebellion with the "Hong Army" and quell the rebellion..."

Yuwen Wen certainly had to refute his son's opinion: "The main problem is not this, you can see..."

He pointed to the Jiaozhou area on the map: "If you want to settle the sun, you will first determine Jiaozhou. If you want to settle Jiaozhou, you will first determine Guangzhou. If you want to settle Guangzhou, you will have to control the Zhenshui waterway and Dayu Ling Road. Once the surface of the ridge changes, the official army can head south from Hongzhou and quickly quell the chaos."

"The problem is that it is thousands of miles away from Hongzhou to Guangzhou, and transportation must be convenient. The situation of prefectures and counties along the way is stable. Only when the official troops attack quickly and powerfully. However, there are many mountains along the line, and countless Li Liao and Man tribes gather. It is not easy to be peaceful."

"Guangzhou is unstable, Jiaozhou will be unstable, and Jiaozhou will be unstable. Even if there are troops stationed in the former site of the south of the Sun, the troops will be just fish in the dry rut, and it will be finished sooner or later."

"If Jiaozhou is unstable, expand its territory southward. These territory will be just dew. When the sun comes out, it will disappear without a trace. Therefore, operating Jiaozhou is the key, but it is not easy to manage Jiaozhou well."

Yuwen Wen said this and pointed to the Nanzhong area: "Look at what is the similarity between Nanzhong and Jiaozhou?"

"Uh..." Yuwen Weicheng pondered for a moment and replied, "Is it because of Jingzhou upstream to Yangzhou downstream?"

"Yes, and, what is the similarity between Guangzhou and Jiaozhou?"

When Yuwen Weining saw his father looking at him, he thought for a while and replied, "Is Huainan to Jiangnan?"

"Yes, this is the key point. There have been conflicts between Jing and Yang for hundreds of years in the Southern Dynasty. Huainan is a barrier to Jiangnan. If you want to defend Jiangnan, you must first defend Huainan, Jingzhou, and Jiaozhou."

"Similarly, if you want to pacify Jiangnan, you must first take Jingzhou and Huainan. In this way, taking Jiangnan will be like taking objects from a bag."

After Yuwen Wen finished speaking, he reached out his right hand to get the paperweight on the table. He only used his thumb and index finger to hold the paperweight (pinch).

"The paperweight is Jiaozhou, the thumb is Guangzhou, and the index finger is Nanzhong. Look, if there is only one finger, how can I hold the paperweight?"

"If something happens in Jiaozhou, the Guangzhou garrison is moving westward to reinforce. The Southern Dynasties have been like this for hundreds of years. However, once the Guangzhou reinforcements are in trouble, the situation in Jiaozhou will become uncontrollable. If there is another army going downstream in the upper reaches of the southern middle, then there is still room for recovery in the Jiaozhou situation."

"The future of operating Jiaozhou is long, and there are more than one benefit of stable Jiaozhou."

Yuwen Wen still held the paperweight in his right hand, raised his left hand, and pointed the gap between his thumb and index finger with his left hand: "The paperweight is Jiaozhou, the thumb is Guangzhou, and the index finger is Nanzhong, so where is the circle they are surrounded?"

The two brothers replied at the same time: "It's Guizhou."

"That's right, Guizhou, Guizhou is located in the upper reaches of Guangzhou. Once something happens, the downstream will not be peaceful. To operate Guizhou, you have to double-team it. Then Jiaozhou and Nanzhong are the key."

"After Guizhou is well managed, the Tanzhou General Administration of North Dongting Lake District will be stable, right?"

"When Guizhou and Guangzhou are divided into the west and east of Lingbing. The situation on the east of Lingbing will be stable."

When Yuwen Weicheng and Yuwen Weining heard this, they nodded in a sudden realization. Yuwen Wen continued: "Back to the point, as the saying goes, where will the skin be attached without hair? Only when Jiaozhou is stable can the former land of Sunnan be stable. Before that, if you are eager to recover Sunnan, it will not last long."

"Just as people need time to digest their meals, Lingbei Guangzhou, Guizhou, Jiaozhou, and Nanzhong have no continuous operation for a hundred years, and it is not enough to be a rock place to the Central Plains."

Yuwen Wen put down the paperweight and sighed: "Life is short, and my father can't see that time. Work harder and wait for peace in the world. Burn incense and pray in the Taimiao to let my father know."

At this time, the father must be kind and filial to the son. I lamented that life is short and there is not much time left. If a son is indifferent, it would be very unfilial. Yuwen Weicheng and Yuwen Weining reacted quickly and quickly expressed their opinions: "The father is in full swing in spring and autumn, and he will definitely live a hundred years!"

"Hey, people will die in the future. In the future, you brothers must work together." Yuwen Wen waved his hand with a smile. He was very open-minded. Even the science and technology of the future cannot guarantee that a person will live to a hundred years old. In this era, it is not easy.

The supreme imperial power is fascinating, and with power, there is a beauty who wakes up the world and lies in the knees of a beauty. Yuwen Wen is of course willing to enjoy it, but he will not eat the so-called immortal pill with severe heavy metals that exceed the standard.

Life is rare in seventy years. Yuwen Wen feels that it would be good if he could live beyond seventy years old, not to mention that if an emperor lives too long, it would become a huge hidden danger to the dynasty. The ready-made example is Emperor Wu of Liang Xiao Yan.

After putting away his feelings, he began to introduce the "international situation" to his son. No matter who succeeds to the throne in the future, as his heir, his horizons cannot be as narrow as those of the emperors in "historical".

The best example is to solve the problem of Turks and Turks divided into East and West, and the Western Turks have conflicts with Persia and Rome. If the Zhou State wants to solve the problems of Turks and grassland nomadic peoples more thoroughly, it is necessary to find helpers.

The ready-made helper is Persia. If the two countries can attack the Turks from both sides, they will be able to achieve twice the result with half the effort. This is also the reason why Yuwen Wen solemnly received Persian envoys.

When it comes to Persia, we must mention Persia's old enemy Rome. Although the struggle between the two countries has nothing to do with Yuwen Wen and he cannot control it, the fight between these two countries has made another force fisherman profit.

Just as the struggle between the Song and Liao countries in history made the Jin Kingdom cheaper, the perseverance of Persia and Rome led to the rise of the Arab Empire.

Of course, this has nothing to do with Yuwen Wen, but he hopes that his children and grandchildren can pay attention to the issue of "crowns and clams fighting each other, fishermen benefiting" and not follow the "old path" of the Tang Dynasty in the original history.

The Tang Dynasty destroyed Baekje and Goguryeo, but Silla was cheaper. The Liaodong region also created a Bohai Kingdom, and at the same time, the Khitan gradually grew bigger.

The Tang Dynasty suppressed the Cuan family in Nanzhong and supported Nanzhao, one of the six Zhaos. As a result, it was a disaster for raising tigers. In the end, it was lost to Nanzhong. Even Shu and Jiaozhou were attacked by Nanzhao.

The Tang Dynasty destroyed the Turks, but the latter Turks were also destroyed. The grassland still had overlords, Xue Yantuo, Uighurs and other forces took the stage.

The Tang Dynasty suppressed Tuyuhun, which resulted in a favorable price for Tubo. Later, Tubo rose up and occupied Longyou, not only attacked Shu, but even broke through Chang'an. Later, it invaded Guanzhong and attacked Caogu every year, causing the Tang army to "prevent autumn" every year.

This is the lesson of history. Yuwen Wen could not say it directly, so he could only make his sons aware of this problem and learn from the lesson through constant teaching.

If you want to achieve "balance" all day long and help one faction fight one faction, you will sooner or later get rid of this practice and raise a tiger.

Yuwen Wen wanted to let his sons know that whether it was Liaodong, Jiaozhou, Nanzhong or the grassland, to completely solve the problem, he could only rely on his own country to enrich the people and strengthen the army and have sufficient food.

"By farming, can the little food support the spread of the edges and last for decades? Of course not, so we have to rely on maritime trade to subsidize expenses."

Yuwen Wen said this and emphasized his tone: "My father worked hard to do maritime trade. He not only had to open source, but also had to expand a new world for the country and the people. It would take decades of operation before the profit would become greater and greater. In the future, you will be the leader. If anyone says maritime trade is exhausted and the people are hurting money, he would suggest that the court ban the sea..."

"This kind of person is either stupid or bad!"
