Strictly speaking, Puban City is the first fortified city that needs to be attacked by Li Po since he raised his army.

Before, like Jinyang, Zhuojun and county towns were all strong cities in the world, but Li Po led his troops to attack them, all of them were soldiers under the city, and the city was already in their hands, and like Mayi, Yanmen, Linfen, Jiangjun, etc., they were all among the people who fell after hearing the wind.

Only the previous battle of Jiexiu was regarded as an attack on the city, but speaking of which, it was not a real assault, tens of thousands of Tang troops gathered in a square inch, and there were still many contradictions inside, coupled with the misjudgment of the Tang army generals on the situation, all of which made the battle of Jiexiu unable to be classified as a strong siege of the city.

And Pusaka is completely different, the Tang army and the Pusaka defenders are waiting for the city, and most of the generals are also dedicated to defending the city.

Outside, on the other side of the Yellow River, there is still a large army of the Tang Army stationed, not isolated.

Therefore, Li Po was very patient at the beginning of the siege.

First of all, I thought about carefully leveling the moat of Pusaka, if it was the first two years, this would definitely be a job to add human lives, and it would be very difficult, because the moat of Pusaka was repaired during the reign of Emperor Wen Yang Jian, and it was connected to the waterway that extended from the Yellow River, in fact, it was part of the channel from Kansai to Jindi.

Therefore, the moat of Kasaka is very wide and alive, and it will take a lot of effort to fill it up if you want to.

Fortunately, there is no shortage of engineering talents under Li Po's command now.

He Chou's two disciples observed the celestial phenomena, and then watched the water situation, and finally started work with people, six days, first sealed the Yellow River waterway, and then dug three ditches around Puban City, dug some big pits, and finally after a few loud noises, Puban's moat water moored out, forming several ditches and ponds around Puban.

Then the soldiers, who had been waiting for a long time, swarmed up, carrying large wooden shelters and carrying dirt bags, and soon filled in the dry moat.

In a few days, Li Po watched the whole process on a small hill, which can be regarded as a deeper interpretation of Li Jingbing's quote from Sun Tzu's Art of War in the book of attacking, "going to the army to attack the army, then attacking the enemy, then attacking the army, and attacking the city again".

Siege warfare is the most helpless strategic and tactical choice for the people who lead the troops, how much manpower and material resources will be consumed, he has seen it once under the city of Liaodong, and this time it has been shown again for him under the city of Pusaka.

Therefore, the fall of the Central Plains city is a specific manifestation of internal and external troubles, and there must be people who surrender for the sake of the people.

In other words, no matter how strong the city wall is, it can't be relied on, the most important thing is the people's hearts, the people's hearts are cohesive, and the people's hearts can be united outside the wilderness.

Under the fluttering sun, moon and stars, Li Po turned his head to look west, feeling that the Tang army on the other side was too quiet, and the troops were a little small, was this trying to tempt him to cross the river without capturing Puban City?

Li Po shook his head and smiled, if that was the case, Li Er would underestimate him Li Po.

Of course, he didn't forget to slander Li Yuan, feeling that Li Yuan was too lucky to rush into Chang'an City so easily.

You look at the beginning of the people, how hard the siege is, you look at the people Li Mi, I don't know how many circles around Luoyang City, you went to fight Chang'an, and it didn't take much trouble to get in, how wasteful do you say the people in Chang'an City have to be?

On the other day, we hit the city of Chang'an, will we also come to enter with a drum?

Emperor, it has always seemed to be very far away from him, but the Yellow River is surging in front of him, and it will not take a day to go to the city of Chang'an after crossing the Yellow River, at such a moment, the word emperor finally became clear in Li Po's heart, and exuded infinite temptation like a demon's smile.

Looking at the dense tents of the large military camp under the hillock, and looking at the battle flags of the various departments fluttering over the camp like a forest...... The surging sound of his heartbeat seemed to remind him that the position of the lord of the world was not out of reach, in fact, it had already been gently placed there, and maybe as long as he worked harder, he would be able to sit on it.

His gaze fell again on the head of Pusaka City in the distance, and the Tang Army banner fluttering on it finally pulled him back from his imagination to reality.

Shi Shiran's reins of the horse, laughing at the people around him: "After this battle, the foundation is just beginning, everyone still needs to work hard, the road ahead of us is still long, don't you say?" ”

The sound of tapping on the cuirass suddenly became one, and the generals around him understood that the siege battle was about to begin, and the importance of this battle had been infinitely raised in the hearts of the generals as the last battle of the foundation that the governor had repeatedly mentioned.

Immediately, Li Po ordered: "Order the generals of the Weifu to discuss matters with the Chinese army tonight." ”

Indeed, the moat of Kasaka has been filled, the siege equipment has long been ready, and there is no need to worry about morale, so the last step is left to siege the city.

Li Po is bound to Pubancheng, he will not leave such a landing bridgehead for the Tang army, because there are still some people behind him waiting for him to clean up, and there are still many things to do, and Li Tang has been fighting and entangled for many years, which is not a situation he wants to see, although Chang'an has been exuding a good smell and a very delicious appearance.

But he has calmed down on the side of the Yellow River, and feels that this is not the best time to attack Guanzhong, even if he is really lucky to win Chang'an City like Li Yuan, what kind of complicated situation will he fall into?

There are enemies everywhere outside, and they will definitely attack him while his foothold is not stable, scattered in Guanxi, and the Tang army in all parts of Shuzhong will definitely form large and small separatist forces, and the intricate gate lords and nobles in Chang'an City are enough for him to drink a pot.

Just like now, he and Li Tang are constantly fighting, how many people are watching the excitement next to him? And how many people have benefited from this?

For example, Wang Shichong, for example, Xiao Miao, for example, Liang Shidu, Li Rail, just like Dugu Huaien, fighting so fiercely is like the rhythm of marrying others.

So Li Po felt that it was time to stop and think of some other ways to change the situation.

Of course, it's still the same sentence, first lay down Pusaka, block the road for the Tang army to cross the river, and at the same time give Li Er a few sticks, otherwise this guy is jumping around, maybe when he will be able to sneak over to him again.

……………………

The next day, the army came out with all the troops, and then it was divided into two parts, one led by Chen Yuan and Zhang Lun to attack the northern city of Puban, and the other was led by Li Po himself to attack the eastern city.

Wei Chi and his subordinates were stationed at the beachhead of the Yellow River to prevent the Tang army from crossing the river to aid Puban.

On this day, the weather was very good, the sky was clear, the sun rose in the east, and the sun shone directly on the earth, so that all living beings felt the breath of spring.

On the banks of the Yellow River, at this time, there are fireworks and fireworks, and the smell of war smoke is getting stronger and stronger.

There were many pillars of smoke rising in the city of Pusaka, that was the defenders in the city preparing to defend the city, above the city, the noise of the defenders came from afar, the figures ran back and forth on the city wall, and the soldiers poured up the city wall, and gradually lined up on the city wall.

The besieging army outside the city lined up in a row, marching slowly forward with neat steps, and the sound of orders came one after another, and soon the army stopped beyond the range of the defenders at the head of the city.

The officers shouted loudly in the queue, making the final pre-battle mobilization and boosting the morale of the soldiers.

The battle flag of the general of Weifu kept moving, and finally stopped in front of his own headquarters, and the orderly siege army put a lot of pressure on the defenders.

Li Ding'an's troops were at the front, and the rumors of invincibility in the attack continued to affect the morale of the defenders for a few days, and in a few days, seeing the wide moat was filled in by the enemy in an orderly manner, it gave the defenders great pressure, so when it was time to really meet each other, the defenders also had a sense of timidity.

But then on the top of the east city, there was a burst of cheers, the battle flag of the Dugu clan moved to the head of the city, and was planted high on the arrow tower at the head of the city, the young Dugu Yanyun personally guarded the east city, and at the beginning showed the heart of dying with the city, and went up to the head of the city to defend the city with everyone.

Dugu Yanyun and Jiang Yuyi are different, he has a reputation for courage among the Dugu clan, and he also has the determination and courage to fight and kill the enemy.

Brave and combative, and desperate to prove his worth with the blood of his enemies.

When he came to the enemy in person and raised the sword in his hand, the morale and combat enthusiasm of the Tang soldiers were immediately aroused, and they raised their weapons one after another, beating their chests constantly, and unsurprisingly showed their determination to hold the city.

The city is still being arranged in an orderly manner, and the changes in the city head seem to be unheard.

It is an indisputable fact that most of the essence of Jindi has been collected by Li Po, they are used to seeing blood and fighting, and have a strong desire to win.

The tenacious will of the Jin people was perfectly reflected in these foot soldiers, and when they arrived in Youzhou, they gradually integrated into this group, and their strength quickly increased.

The Youzhou infantry has always been called the elite, they brought rich combat experience and skills to the Jin land infantry soldiers, and what is even more rare is that the Youzhou infantry soldiers have not only fought against the Hebei bandits, but many of them have also attacked the fortified city of Liaodong with the army.

It can be said that today, when it comes to attacking the city, there is no more powerful army than the Youzhou foot soldiers, even the brave and fierce Qin people who live on the Qin River for eight hundred miles must bow down in this regard.

The long sound of the horn finally remembered that it was the first note of the beginning of the war.

Looking down from the sky, a group of soldiers like ants, holding a round shield in one hand and a ladder on their shoulders, advanced from the front row of the siege army to the bottom of the city.

The siege began......
