Li Shimin faked his death? Then I will be powerful enough to conquer the world!

Huaiyuan City was an important military town of Goguryeo. Its terrain was dangerous and its city walls were strong. It had always been one of the important lines of defense for Goguryeo against foreign enemies.

It is known as the gateway to Liaodong.

The city lord Chi Duhe gradually relaxed his vigilance during these seemingly peaceful days.

He was sleeping soundly on the comfortable couch in the inner room of the mansion, dreaming sweet dreams, with a satisfied smile on his lips.

Suddenly, there was a loud "boom", as if the sky was falling and the earth was splitting apart. This huge sound instantly shattered Chiduhe's dream.

He suddenly woke up from his sleep, with a hint of haziness still in his eyes.

Chi Duhe hurriedly got up from the couch, not even having time to put on his coat, and shouted loudly: "What's going on! Where does such a loud noise come from!"

His voice was panicked, echoing in the empty room, filled with anxiety.

Chi Duhe's loud shout immediately threw the servants and soldiers outside into chaos. They rushed in in a panic, with a look of panic on everyone's face.

"Rusa, bad, bad! The Tang army is coming!"

A soldier shouted in a trembling voice. His body was shaking constantly and he could hardly stand. He was frightened out of his wits by this sudden change.

Hearing the report from his subordinates, Chi Duhe was stunned. He stood there, eyes wide open, his mind instantly blank.

After a moment, he seemed to come to his senses suddenly. He rushed forward angrily, grabbed the man's collar with both hands, shook him vigorously, and shouted: "What did you say? The Tang army broke in? How is this possible?"

His eyes widened and he stared at the soldier.

"The walls of our Huaiyuan City are so strong. They are built with huge stones and have withstood years of wind and rain without wavering. There is also the Great Wall outside as a barrier. How did the Tang army get in?"

Chiduhe couldn't understand it no matter how hard he tried, and was extremely angry.

Back then, before he left, Yeon Gaesomun had repeatedly warned him to defend Huaiyuan City well and not to slack off in the slightest, as this was a crucial place concerning the life and death of Goguryeo.

Chiduhe kept his mission in mind and devoted himself to the city defense affairs since arriving in Huaiyuan City. He not only strengthened the training of soldiers, but also organized manpower to reinforce the city walls to make them more solid and durable.

After a long wait, more than half a year passed, but there was still no sign of the Tang army.

Gradually, Chiduhe's tense heart began to relax. He felt that the Tang army might not come, so he began to enjoy life.

He drank and had fun in his mansion every day, and had fun with his wives and concubines.

Although he enjoyed it, as a member of Yeon Gaesomun's family, he did what he should do.

The fact that he was allowed to guard the gateway to Liaodong also shows Yeon Gaesomun's trust in him.

But who could have imagined that they had just started to enjoy themselves for a short while, and when they opened their eyes, they found that the Tang army had already invaded.

Chiduhe was really confused at this time. He had made an unforgivable mistake.

After losing Huaiyuan City, even if he could return to Goguryeo alive, Yeon Gaesomun would never let him off easily with his harsh methods, and might even skin him alive.

"Rusa, I don't know how the Tang army managed to cross the Great Wall."

The soldier answered tremblingly, his voice as soft as a mosquito's hum.

After hearing his subordinates' words, Chi Duhe was silent for a moment. His brows were tightly furrowed, and he was thinking quickly about countermeasures in his mind.

"What about the walls of Huaiyuan City? Why didn't you report the Tang army's attack on the city?"

Chiduhe asked loudly.

Hearing Chiduhe's words, the subordinate was so anxious that he almost cried. His eyes were red and tears were welling up in them. He said in a sobbing voice: "Rusa, stop talking, run for your life, if you don't run now, it will be too late!"

He said it almost in a pleading tone.

"The Tang army didn't attack the city at all. The walls of Huaiyuan City were just collapsed by thunder!"

Hearing that the city wall had just been collapsed by thunder, Chiduhe became a little anxious.

Although he was confused, he knew at this moment that the situation was critical and that staying here would only lead to death.

So, without saying a word, he released his hand that was grabbing the soldier's collar, turned around and ran out with his men.

He was very scared, but he knew better that going back and being punished by Yeon Gaesomun was one thing, but if he didn't run away now, he would be hacked to death by the Tang army, which was an imminent danger. Saving his life was the top priority.

Outside Huaiyuan City, Li Chengqian was wearing armor and riding on his beloved horse.

He quietly watched the Tang army pouring into Huaiyuan City, his eyes revealing a calmness. Everything was under his control.

Li Shimin brought a group of veteran ministers to watch the battle. These veterans were all famous for their military achievements and rich in experience, and they all had varying degrees of surprise on their faces.

They had fought for many years, but had never seen such a simple siege.

Just one round of artillery fire not only opened the gates of Huaiyuan City, but also frightened the Goguryeo soldiers into disarray, forcing them to flee in all directions without any ability to resist.

Looking at Huaiyuan City being violently blown open, Li Shimin finally breathed a sigh of relief.

He has always had a knot in his heart about Goguryeo, a serious threat, and has been brooding over it for many years.

Not only him, but even Li Chengqian had tolerated Goguryeo for a long time.

This is also why after Li Chengqian came to power, he couldn't wait to build a road to Goguryeo, so that he could completely solve this hidden danger one day.

The threat that Goguryeo posed to the Tang Dynasty was too great. This threat was not limited to territorial disputes, but because they had already formed their own unique civilization. If they were left alone and allowed to grow and develop, they would inevitably become a major threat to the entire Han civilization in the future.

Their culture, customs and political system are very different from Han civilization. If they are not curbed, they may have a serious impact on the inheritance and development of Han civilization.

Therefore, whether for the territorial integrity of the Tang Dynasty or for the inheritance and development of Han civilization, they must take action against Goguryeo and completely eliminate this potential threat.
