As Li Ye expected, the envoy who went to the Bohai Kingdom ten days later brought back the news that Da Weiying, the king of Bohai, was willing to pay tribute to the Tang Dynasty again and obey the edict of the Tang Dynasty. Also returning were the envoys of the Bohai Kingdom.

Li Ye did not summon the envoy of the Bohai State in Liaodong City, but arranged for the other party to go directly to Chang'an to pay tribute. As for the letter of state presented by the envoy, the suggestion that King Bohai Da Weiying took the initiative to send army monks to fight with the Tang army, but Li Ye politely refused.

He didn't look down on the strength of the Bohai Kingdom, and let them participate in the war, most of them would only be held back.

The next action was logical, and the Tang army crossed the Yalu River in batches and went straight to the Datong River basin.

At this time, the situation on the peninsula was that the northern part was the Later Goryeo Dynasty established by the Gong descendants, also known as the Later Goguryeo, and the territory area was still the largest, the southwest was the Later Baekje Dynasty established by Zhen Xuan, and the southeast was still the Silla Dynasty.

Therefore, the opponents that the Tang army had to fight first were not much different from those more than two hundred years ago, they were all Goguryeo. It's just that compared with Goguryeo back then, the current territory of Goguryeo is too small, and a large area of land in the north has fallen into the hands of the Balhae Kingdom.

Because the upper reaches of the Taedong River were in the hands of the Balhae State, and the lower reaches to the sea were in the hands of Later Goguryeo, the first important target of the army was Pyongyang City.

"Ten years ago, when Silla was in civil strife, thieves were rampant, and the first to raise the banner was the current Later Baekje King Zhen Xuan. This so-called descendant of the post-Goguryeo king, originally a descendant of the Goguryeo royal family, did not raise his army in the territory of the former Baekje, but in the north.

Later, he gradually occupied a large area of the original Goguryeo, and after Zhen Xuan proclaimed himself the queen of Later Baekje, he also called himself the king of Later Goguryeo, which can be regarded as a great position of achievements in a hundred bloody battles. ”

On the way to rest on the march, Niu Dan chatted with Ergouzi about the opponent to be cut off in this battle.

Nowadays, Niu Dan is no longer the head of the capital, but the deputy commander of the capital, and the second dog is already the commander, and because he has been in the Chang'an Training Institute for two years, his name has also been changed, and he is called Xu Zhong, that is, the surname plus the ranking.

Both of them are soldiers of the forbidden army at the moment, and they are stationed in Youzhou on weekdays, and this time the army is going eastward, and the troops mobilized are all forbidden army teams near the northern border, and they are also among the battles.

"Compared with the Khitans, aren't these Koreans much worse? It seems that this time the war will be smoother, and the military merits will be easy to obtain. The second dog laughed twice and rubbed his hands.

Niu Dan gave him a slap on the head, and scolded angrily: "You are already a commander, why are you still so uncalm, when you get to the battlefield, you can underestimate the enemy? All opponents, before they become dead, are worth your best!"

Ergouzi nodded hurriedly, but the laughter did not stop, and he obviously didn't listen to Niu Dan's words too much, and his face was full of beautiful yearning for military achievements.

Niu Dan understands the mood of the second dog very well, after all, the other party has not been married for a long time, and he has just had a child, and now he is full of thoughts about making contributions and fighting for the future of his wife and son. Men are like this, after starting a family, they want to hurry up and develop their careers, so that their wives can enjoy prosperity and wealth.

As a person who has come over, Niu Dan has to carry out ideological education for Ergouzi every day, the core is to let him take it easy, don't remember to fight hard when he arrives on the battlefield, and being able to go back alive is the biggest responsibility for his wife.

At this time, Later Goguryeo went to the Gong descendants and also learned the news of the upcoming attack of the Tang army.

As a descendant of the royal family, the Bow Descendant is quite far-sighted and has a great heart, and ten years of battlefield battles have also cultivated him in all aspects

The quality of the heroes - although he has been fighting for ten years, he has not played a territory of thousands of miles.

When the whole world attacked the Tang Dynasty before, the monks who were sent to respond to the call of the Khitan were the Gong descendants.

The Silla Dynasty was already decaying, and the country could not be pacified even if it was in turmoil, so naturally there was no time to be distracted. Moreover, now that the Silla territory is far away from Datang, and Baekje is in a safe corner, there are not so many ideas.

Emotionally speaking, he didn't want to see the Tang Dynasty become strong again, and intellectually speaking, if the Tang Dynasty regained its heyday, it was possible to send troops to Goguryeo again.

So he sent some monks to participate in the grand event with the Khitan.

It's a pity that the final result is not good. The world's attack on the Tang Dynasty was as mighty as the offensive, Mo said that it failed to destroy the Tang Dynasty, and even failed to prevent the Tang Dynasty from flourishing, which made the Gong descendants very unhappy in the past two years.

Most of the reasons for unhappiness are due to worry.

Upon learning of the Tang army's attack this time, the Gong descendants were almost shocked, and after repeatedly confirming that the news was correct, they hurriedly gathered their important ministers to discuss the strategy of dealing with the Tang army's attack.

In the past, those military generals who were in Goguryeo, who were also considered to be vertical and horizontal, heard that the Tang Dynasty came to attack, and most of them were frightened, and they were so frightened that they couldn't come up with an effective strategy for a long time.

A small number of them are immersed in the glorious achievements of the past conquests, and they can't understand the strength of the Tang Dynasty at all.

Faced with the noisy courtiers, the bow descendants were very sad.

His family knows his own affairs, not to mention anything else, the prosperity of the Khitan soldiers and the strength of the monks, he still knows that even the dilemma set off by the Khitan and the Quartet has been torn apart by the Tang Army in less than a year, how can he dare to be arrogant?

Just when the Bow Spawn couldn't sleep at night, a turning point appeared.

The monk who went to spy on the military situation reported that the Tang army had only dispatched 100,000 infantry to attack this time.

"Only 100,000 paces?" When the Bow Descendant heard this number, he was like a person standing on a cliff, and suddenly found that the so-called cliff was actually only one zhang high, and it would not bring danger to himself at all, and he couldn't help but look up to the sky and laugh in surprise.

"It's too underestimated to launch only 100,000 cavalry to attack us!"

"The Tang Dynasty is too proud and complacent, they just bring humiliation on themselves!"

"Just 100,000 soldiers and horses, this is simply here to die!"

When the civilian-military generals were informed of the news by the Bow Descendants, they cheered up almost at the same time. In their eyes, the Tang Dynasty was carried away and did not take them seriously, and this arrogant strategy of using troops undoubtedly gave them a once-in-a-lifetime opportunity.

"Great King! The Tang Dynasty deceived people too much, and the last general categorically could not tolerate it, please ask the king Xu to go on the expedition, and the last general will definitely let the Tang Dynasty know what it means to be an elite soldier in a hundred battles!"

"King, please be the vanguard!"

The generals were not only happy, but immediately asked for battle. Even the most pessimistic people before, after learning that the Tang army was only 100,000, had the will to fight.

The Bow Spawn was pleased with the reaction. The current Goguryeo is indeed not strong, and it is not comparable to Goguryeo more than two hundred years ago, and if the Tang Dynasty attacked with heavy troops, he would really be uneasy.

But now it seems that Li Ye, the emperor of the Tang Dynasty, is not as good as others, and after winning a big war like the world's attack on the Tang Dynasty, he is still there

It's the same as everyone else, inevitably inflated. Now he only wants to use 100,000 soldiers and horses to destroy Goguryeo, this is making a mistake and giving himself a chance!

The bow descendants smiled, twisted their beards and thought for a while, they still thought that they should not be careless, the Tang army's combat power was still very strong, and they must go all out to defeat the Tang army cleanly and decisively, and beat the Tang Dynasty badly, so that they knew that they were powerful, and they would no longer covet this land all day long.

Thinking of this, the Gong descendant began to order: "Pei Xuanqing, this king has ordered you to be the defense envoy of the northern camp, and rush to Pyongyang City on the same day to preside over the Pyongyang war. Shen Chongqian, this king ordered you to announce the consolation envoy for the northern camp and cooperate with General Pei in the battle. The two of you must not let the Tang army cross the Datong River on this trip!"

Pei Xuanqing is the most brave and warlike general under the command of the Gong Descendant, and Shen Chongqian is the most resourceful strategist under his command.

Pei Xuanqing and Shen Chongqian got up one after another to receive the order, both of them were high-spirited and full of confidence, "Don't worry, the king, we will let the Tang army come and go!"

In late July, the Don army completed its buildup outside the city of Pyongyang.

After Zhao Poyu inspected the city defense of Pyongyang, he turned back to Li Ye and reported: "Your Majesty, the city defense of Pyongyang City is very tight, the moat has been urgently accelerated and dug deeper, the city wall has also been strengthened and heightened a lot, and all kinds of defensive equipment are very complete. ”

After the Tang army entered the territory of Goguryeo, it did not encounter any large-scale resistance along the way, and the Goguryeo army and monk Mo said that they did not appear in the wild, and even several large and small cities in the border areas were directly abandoned by the other party.

Obviously, Goguryeo concentrated its forces on the front line of Pyongyang City, in order not to give the Tang army a chance to break through, and clenched its five fingers into a fist, so that the Tang army could not capture the fortified city with an absolutely superior force, and could only return in vain in the end.

Li Ye was not surprised by Goguryeo's strategy, it was a very wise choice, "How many defenders are there in Pyongyang?"

Zhao Poyu replied: "According to the observation of the last general, and then the intelligence of all aspects, there are no less than 200,000 defenders in Pyongyang City, and there are no less than 50,000 elite soldiers in each of the two acropolises on the left and right!"

Pyongyang City and the two acropolises on the left and right, with the help of the terrain, form a zigzag defense system, which is quite difficult to solve from a strategic point of view.

Li Ye showed an inexplicable smile, "In the face of 100,000 cavalry, 300,000 soldiers and horses actually stood in the city to defend it, I have fought a lot of battles in my life, but this kind of strange war has not been fought yet." ”

Zhao Poyu naturally understood what Li Ye meant, and said with a smile: "If it were in our country, the war would naturally not be this way of fighting, and the Tang people didn't care about the habit of being a turtle with a shrunken head." In the opinion of the ministers, these Koreans are probably frightened......"

The strength of the besieging side must be several times that of the defending side, which is the normal state of war, and without several times the enemy's strength, the attack and defense will not dare to attack the city. In the same way, if the defender has several times the number of troops, it will not defend the city wall, but will take the initiative to fight the enemy in the field.

After all, although defending the city is advantageous, it is a great harm to the city itself, and the houses and buildings in the city, the wealth and the people will suffer great losses in the war. Therefore, defending the city is often the last tactic to be adopted.

Li Ye waved his hand, signaling Zhao Poyu not to say much, and said directly: "Gao Li thought that when he was a turtle with a shrunken head, he could save his life, but he didn't know that this also had to be hard enough for the turtle shell." Command the three armies to attack the city tomorrow, and I want to let the Goryeo people know that the 70,000 foot soldiers of the Tang Dynasty are enough to conquer any fortified city in the world!"

"Command!"
