Dangxiang fled, Goryeo was destroyed, and Jurchens were also appeased. The north could no longer affect the power of the Song and Liao countries, which made both countries focus all their attention on each other. The Song Dynasty was the first to take action. With the formulation of the harassment strategy, the Song Dynasty took the initiative to send troops from the northwest and Hebei to harass the border of the Liao Kingdom, and even sent a small group of troops to enter the Liao Kingdom.

When Li Shimin attacked Goguryeo for the first time, he failed to destroy the country in one fell swoop, so he adopted the same strategy of exhausting the enemy. After all, the national strength of the Tang Dynasty was far stronger than that of Goguryeo, so the Tang Dynasty could consume it, but Goguryeo could not afford it. In the end, Goguryeo was tortured by the Tang army, which made Emperor Gaozong Li Zhi destroy Goguryeo in one fell swoop.

The Song Dynasty now also adopted the same tired strategy. This was a dignified open plot. Although the Liao Kingdom saw through the Song Dynasty's plans at a glance, there was no solution at all. After all, the initiative is in the hands of the Song Dynasty. The other party will fight if they want and return if they want. They can only passively deal with it.

The northwest direction is better, there is an endless grassland. Even if the Song Dynasty sent troops, there were grassland people in front of it, which would be difficult to hurt the Liao Kingdom's confidant. At most, it would make some grassland tribes disinterested with the Liao Kingdom. However, the Liao Kingdom did not pay much attention to those grassland people who were not loyal to it.

But the direction of Hebei is completely different. Since the Song Dynasty occupied Yanyun and repaired the Great Wall Defense Line, the Liao army was completely blocked from the Great Wall. The Song army could break out of the Great Wall from several directions. Opposite the Great Wall Defense Line was the heart of the Liao Kingdom and the richest area of ​​the Liao Kingdom.

The Liao Kingdom is located in the northeast and has a long winter, so the closer it is to the south, the more suitable the climate for grain cultivation. Before Yanyun was lost, Yanyun was the granary of the Liao Kingdom. Later, Yanyun was lost. The area north of Yanyun became the most important area of ​​the Liao Kingdom, but now it directly exposed the threat of the Song army.

Of course, the Song Dynasty also knew the weakness of the Liao Kingdom, so every spring and autumn, it would organize troops to fight out from Gubeikou and other places. When it encountered the population, it would be fleeing back to the Song Dynasty to settle, and when it encountered the fields, it would be destroyed by them. It also tried to avoid direct battle with the Liao army and always left at once, which also made the Liao army exhausted.

The continuous loss of population and the destruction of the fields caused the Liao Kingdom to even have food shortages. Some Liao people who were unable to eat enough to risk fleeing to the territory of the Song Dynasty, but the Liao Kingdom had no choice but to watch themselves weaken day by day.

In the past five years, the Song Dynasty has continuously sent troops to weaken the strength of the Liao Kingdom. The Liao Kingdom could only struggle to support it, but it could not stop its own strength from declining rapidly. Even the Goryeo continued to resist. Many times, the Song Dynasty supported it behind it, which also caused the Liao Kingdom to fall into the quagmire of Goryeo and could not escape.

In contrast, the Song Dynasty has developed rapidly in the past five years. The Yusilu tribe in the west was annexed by the Song Dynasty, and the Huang-headed Huihe also begged to support him. In this way, the Song Dynasty finally completely opened up the passage of the Western Regions and extended its hands to the Western Regions again.

However, Li Yuanhao took Kucha as the foundation and tried to annex most of the land of the East Karakhan to the west. He has now become the overlord of the Western Regions. The Song Dynasty is not able to transfer its troops to the Western Regions for the time being, which also makes Li Yuanhao not have to worry about the threat from the Song Dynasty. Moreover, it is said that Li Yuanhao also planned to develop westward and even invaded part of the territory of the Seljuk Empire.

Compared with the Western Regions, the Song Dynasty achieved greater achievements in the ocean. Before, it was just a few private activities of maritime merchants overseas. However, since the Song Dynasty's court intervened in this kind of development, the entire Nanyang has become the back garden of the Song Dynasty. Countless Song people took boats to search for wealth and opportunities in the islands of the South China Sea. Almost every day, news of people getting rich came out.

However, the natives in Nanyang were a problem, especially many natives were not civilized at all, and even preserved the bad habit of eating people. The only ones who could educate these natives were probably the only saints, so the Song Dynasty could only send them to see the saints, hoping that the saints could change to vegetarians by these meat-eating guys.

In addition to the natives, the biggest threat to Southeast Asia is its harsh climate and various epidemics. At this time, the medical school was used. After years of development, this medical teaching institution founded by Li Zhang trained countless doctors for the Song Dynasty and established branches in various places. At the same time, they were also responsible for the research on solving some difficult and complicated diseases. Many diseases that were previously considered terminal illnesses have now been solved. In addition, modern medicine in later generations has also begun to integrate traditional Chinese medicine, which has led to the development of medicine very fast, and even affected other disciplines, such as biology, chemistry, etc.

In fact, gold and spices in Nanyang are not the most important. The land in Nanyang is fertile and is particularly suitable for growing rice. There are also various tropical unique economic crops. In addition, large areas of land can also allow more Song people to immigrate, greatly alleviating the land pressure of the Song Dynasty, especially the problem of land annexation, and there is a good solution. After all, there are many lands now, and many landlords cannot find enough tenants at all. Without tenants, there will be no land output. As a result, the price of land has also dropped greatly.

With the expansion of territory, redundant officials have long been no longer a problem, and there are even insufficient officials. Of course, the conditions in Nanyang are a little worse, and many officials are unwilling to go. However, the Song Dynasty began to relax some conditions and promote some officials to become officials in Nanyang. As long as they serve for a certain period of time, they may be transferred back from Nanyang, which has greatly stimulated some people's motivation.

In addition, Li Zhang spared no effort to promote overseas customs and favors in newspapers over the years, which also inspired many people's enthusiasm for exploration in the outside world, especially some young people, who are unwilling to be bound by their families, so overseas has become an opportunity for them to get rid of their family control. Even some young scholars have devoted themselves to overseas. Even if they do not participate in the imperial examination, they have served as an official overseas for several years and as long as they perform well, they will easily enter the officialdom in the future.

The development of the South Ocean and the Western Regions has also opened up all the trade routes between the sea and land of the Song Dynasty. With the productivity of the Song Dynasty far surpassing other countries, various commodities are constantly transported to Central Asia, West Asia and even the Mediterranean. All routes are filled with merchant ships of the Song Dynasty. Even Li Zhang is already planning to organize a global voyage. As long as he is willing to pay, someone will definitely be willing to participate in this feat that is destined to be recorded in history.
