I have already established my power and prestige, so how did Li Shimin come back to life?

In the political chess game, only those who are at the pinnacle of power or those who have accumulated rich life experience can vaguely perceive the potential threat posed by Goguryeo.

Li Shimin was able to clearly sense the danger of Goguryeo, which came from his foresight as an outstanding leader and his ability to control the world situation in detail.

As an emperor, it was his duty to maintain the long-term stability of the empire. Any hidden danger that could shake the foundation of the Tang Dynasty forced him to remain vigilant at all times, and Goguryeo was undoubtedly that hidden danger.

Li Chengqian's awareness of the danger to Goguryeo was not just because he inherited the throne and ascended to the throne.

As early as when he was the crown prince and was studying the rise and fall of ancient and modern times in Xianyang, he discovered that many characteristics of the country of Goguryeo were strikingly similar to the Japan after the Meiji Restoration that he was familiar with.

This similarity is not a coincidence, but a deep-seated commonality that makes Li Chengqian feel uneasy from the bottom of his heart.

Goguryeo, this vast land gave birth to a brave and warlike nation.

Its people have an almost instinctive admiration for the use of force. They have grown up under the influence of martial spirit and regard fighting as an honor. No matter where they are, their figures are always accompanied by the sound of swords and spears.

In the political field, Goguryeo demonstrated a high degree of organization. Its administrative system was strict and efficient, with officials at all levels performing their duties and working closely together, enabling government orders to be conveyed and implemented quickly and accurately.

Ensure that they can respond quickly to various complex situations, allocate resources in an orderly manner and meet challenges.

Its level of civilization has continued to accumulate over the years, with a unique language and writing, rich etiquette and customs, and a unique artistic style. These cultural elements blend together to form the unique civilization symbol of Goguryeo.

Like the Tang Dynasty, this country implemented a centralized system. The king was high above everyone else and held the highest power in the country. He was able to centrally allocate the country's human, material, and financial resources to various aspects such as national construction, war preparation, and external expansion.

Its vast territory, spanning mountains, rivers, plains and hills, has a relatively broad strategic depth, which means that when facing external military pressure, they have enough space to carry out strategic transfers and roundabout operations.

It will not collapse under the first round of enemy attack, can withstand the consumption of a long-term war, and has the strength to compete with major powers.

The Goguryeo people also attached great importance to cultural education, and the cultural level of the entire country was generally high.

This development model that emphasizes both civil and military affairs has further fueled its ambition to expand outward.

Such a country with huge potential and great ambition is a major concern for any emperor in the Central Plains.

As the only country that dared to openly challenge the tributary system of the Sui and Tang empires, Goguryeo's actions were undoubtedly a serious provocation to the Sui Dynasty at that time and the Tang Dynasty today.

It directly impacted the hegemonic order established by the Tang Dynasty in East Asia.

In this era when international relations were maintained by the tributary system, the submission of various countries to the Tang Dynasty was an important manifestation of the Tang Dynasty's majesty. Goguryeo's rebellious behavior was undoubtedly a direct challenge to the Tang Dynasty's majesty, attempting to break this established international pattern and establish its own hegemonic position.

Li Shimin might also care to a certain extent about the hegemony of the Tang Dynasty and whether the East Asian countries would submit to him. After all, this was related to the reputation of the Tang Dynasty.

Li Chengqian, however, has a purer belief.

As the population of the Tang Dynasty grew steadily and the national strength gradually grew, in Li Chengqian's mind, the entire East Asia would sooner or later become the territory of the Tang Dynasty. It was only a matter of time.
