Gao Yanshou's reinforcements watched Liaodong City being breached, and they couldn't do anything. Since they were attacked by them, the Tang army had set up a position against them, waiting for them to enter the encirclement to avenge the day's revenge.

Gao Yanshou naturally wouldn't be so stupid and throw himself into the net, he is also a famous general of Goguryeo, knowing that if he works hard face to face with the Tang army, his 100,000 people are estimated to be wiped out in two days, and now Goguryeo does not have many troops that can be maneuvered, judging from the news from the scouts, the Tang army has mastered a powerful weapon that can easily collapse the city wall, which is also the reason why Liaodong City fell so quickly.

The troops of the Tang Army were hanging from afar, and they followed the main force of the Tang Army like this, looking for an opportunity to bite them hard, but the main generals of the Tang Army were all experienced in the battlefield, how could there be flaws for them.

The Tang army marched for more than ten days and came to the city of Jian'an, now Li Shimin knows that his time is precious, and the gunpowder and grenades are also exposed in front of Goguryeo, he is not covering, when he arrives at the city, he directly uses gunpowder to blow up the gate of Jian'an, and then it is still the same as Liaodong City, with firearms battalion soldiers in front of the road, ordinary soldiers of the Tang army attack behind them to kill and injure the enemy, and it is also two days to break through Jian'an City, the same is to capture countless people, the most important thing is to get a large amount of grain and grass, This greatly alleviated the difficulties of the Tang Army's logistical supply.

"Haha, this is a trick to eat all over the world!" Li Shimin stood under Jian'an City and looked at the smoking city, and his heart was full of complacency: "My Datang is strong, and I don't need any conspiracies and tricks at all, just push it over so dignifiedly, no matter what he does, we will drop ten times with all our might." ”

"That is, Your Majesty has been on the battlefield for decades, and of course he is as wise as a torch. It's just that some people always rely on their own little credit, thinking that they are peerless famous generals, and they are still making axes in front of His Majesty, which is really ridiculous and generous! Cen Wenwen first slapped Li Shimin's ass, and then stepped on Li Dongsheng slightly, he was too popular during this time, so let him calm down.

"I'm still young, but I'm still loyal." Li Shimin replied casually, turned to Li Ji and said, "How is Gao Yanshou's army?" Or do you follow us like this? ”

"Back to Your Majesty, when our army attacked Jian'an City, they also wanted to come over and sneak attack, but under our strict formation, they still didn't dare to act rashly." Li Ji replied: "The next one is Anshi City, the city lord is Yang Wanchun, known as the first Goguryeo to defend the city, if he holds on for a long time, Gao Yanshou's army is really a trouble." ”

"There is a firearms battalion, what strong city in the world cannot be broken?" Li Shimin pointed to the city tower in front of him arrogantly: "Before Jian'an City, did we think that we could break it in two days?" The guards here are also few in the world, isn't it easy to blow up the city wall with gunpowder? Haha, Li Dongsheng, this kid is really a good thing! ”

Ten days later, Li Shimin led the army to the city of Anshi. Ignoring the fatigue of running around his body, he took Li Ji and other civil and military forces to the city of Anshi, and looked at the last important town before Pyongyang City with great interest. Li Dongsheng also arrived in the logistics team, he knew that this Anshi City had blocked the invincible Tang army for several months in the real history, and it was not until the winter that the logistics supply of the Tang army could not keep up with the troops that he had to retreat, which was also a rare battle in Li Shimin's life without victory.

Li Shimin felt that this city was no different from Liaodong City and Jian'an City, that is, the city walls were a little higher and thicker, but these were not things, it was nothing more than a little more explosives. Now the city is often attacked, and the soldiers of the firearms battalion are also very handy with gunpowder, and practice makes perfect.

At this time, a hot air balloon had risen in the middle of Tang Jun's barracks, and even though Tang Jun had repeatedly said that they should not panic, they still caused a lot of noise in the barracks.

The hot air balloon is no longer a secret weapon, after the city of Gaochang, spies from various countries have heard about this thing, and everyone is not stupid, even if you use it twice, there are not many people who are intimidated after using it a few more times, even Goguryeo is no exception, they are pointing at the hot air balloon on the head of the city.

Although it can't be used in battle, it is really useful to reconnoiter the situation in the city, as the saying goes, standing tall and looking far away, understanding the terrain of the city and the enemy's layout is the most important thing in the army. The soldiers on the balloon kept throwing the bamboo tube down, and someone below was combining the drawings, and then writing and drawing on the map according to the signs above, and soon a map of the defense of Anshi City and the drawings of the city's roads appeared in front of Li Shimin's eyes.

"There are a lot of barracks in Anshi City." Li Shimin looked at the drawings carefully and said, "How can there be so many people?" Do they have enough food to eat? ”

"Your Majesty, Anshi City is a key place for Goguryeo, if it is lost here, there will only be a Bogou Pass between our army and Pyongyang City, so Goguryeo will definitely not sit idly by and watch Anshi City be breached, so it is normal for there to be many defenders in the city." Cen Wenwen also did a lot of work on Anshi City.

"Your Majesty, the name of the lord of this Anshi City is Yang Wanchun, who is a famous general in Goguryeo, and he is very good at defending the city. It is said that his subordinates are brave and good at fighting, when Goguryeo Mo left the Zhiquan Gai Suwen to kill the monarch and usurp power, the princes in the country are afraid to be angry, only Yang Wanchun is not afraid, openly declare that he is not satisfied with the propaganda, Quan Gai Suwen hated it deeply, so he poured the country's troops to attack Anshi City, attacked for several months but did not capture Anshi City, and finally could only withdraw his troops abruptly, which shows his military talent. Li Ji squinted his eyes and said: "We still have to be cautious when such a person guards the city." ”

"Yes, Your Majesty. Since our army entered Goguryeo, it has been marching and fighting, and the soldiers are very tired, but this Yang Wanchun is waiting for work, even if there is gunpowder in hand, they must have made preparations. I estimate that this must be a protracted siege war, I am afraid that more than 200,000 soldiers and horses of our army will besiege Anshi City, Quangai Suwen just has a chance to breathe, he can just transfer troops and horses from all over the country, and when the time comes, together with Gao Yanshou's reinforcements, and the defenders of Anshi City will attack inside and outside, our army is very dangerous! "It was Zhang Jian who spoke, and he was also the commander-in-chief of the siege.

"There is no need to raise the morale of the enemy and destroy your own prestige." Li Shimin disagreed: "No matter how strong the city is, we will directly blow it up, and then we can just fight directly, my Tang Mansion army is facing the enemy head-on, and it is worth no one." But what you said also makes sense, I still think that it would be better to besiege the city and send reinforcements, and it would be better to destroy the reinforcements of Goguryeo. ”
