By the time the infantry battalion attacked, the Shooting Battalion, the Left Guard Battalion, and the Pioneer Battalion had already reached the outer wall of Sindu.

Although the collapse was only a section of the eastern city wall, the outer city wall at this time was no longer guarded, and the entire city was already empty.

According to the agreement between Du and Yanghu, an hour after the infantry battalion launched the attack, the other three battalions including the Shooting Battalion would also open the city gates, and the troops would divide into three routes and launch an attack on the inner city of Xindu City.

Although an hour is extremely short, it seems to be a torment for the waiting Merge Army, who look up at the sun from time to time, calculate the time, and are full of longing for battle in their hearts.

Du Yu has a special hourglass to see the time, the army of the shooting battalion has already gathered outside the west gate, and even the bolt of the city gate has been sent to sneak into the city quietly and open, and the entire gate is hidden. When the sand in the hourglass was dripping, Du Yu finally drew his long sword and ordered loudly: "Attack!" ”

The gate to the west of the city was pushed open, and the state army entered along the gate hole and launched an attack on the inner city.

Due to the barrier of the outer city wall, the defenders of the inner city could not see how many men and horses the state army had gathered outside the city.

At the same time, the south and north gates were also opened, and the Left Guard Battalion and the Xianden Battalion swarmed in, also launching an attack on the inner city of Sindu.

The state army launched an attack on the letter from all sides, and the cities within a radius of more than ten miles were caught in the fierce battle, and the momentum of the state army was like a rainbow, the crowd was like a sea, and the sound of killing shook the sky.

After receiving the reports from the city gates, Lu Zhao couldn't help but look worried, and glanced back at Lu An, it was he who followed Lu An's advice and did not draw troops from everywhere, otherwise, he would really not be able to deal with the current situation.

The 30,000 descendants under Lu Zhao are the pillars that Lu Zhao relies on to defend the city, although he still has a new army of 40,000 people in his hands, but the combat effectiveness of these new troops Lu Zhao does not dare to compliment, if these new troops are really allowed to stand alone, Xindu City is really dangerous.

The reason why Le'an was lost in such a short period of time completely proves that these new troops are useless, because Le'an's defenders are all newly recruited troops, and they are really vulnerable in front of the Bingzhou army.

Therefore, in the city defense system of Xindu, Lü Zhao did not dare to rely on the new army at all, and more gave important defensive tasks to his old troops, 30,000 horses, and Lü Zhao distributed them evenly to the four city gates, each with 7,000 people. The remaining 2,000 people stayed in the city as a reserve, but also to ensure the safety of the city, after all, the war together, the situation became chaotic, it is possible that there are also lurking spies in the city of Xindu, in order to prevent them from fishing in troubled waters and sedition, Lu Zhao in the case of a shortage of troops, or a team of men and horses, responsible for the security of the city.

Just now, Bingzhou took the lead in launching an attack at the east gate, the battle was quite fierce, and the Jizhou army was very difficult to defend, Lu Zhao followed the advice of the Liang Dynasty, and had the intention to draw out a part of the old troops from other places to reinforce, but fortunately, thanks to Lu An's reminder, Lu Zhao did not make a mistake.

The offensive of the state army was so fierce that the city gates were tightened everywhere, and the existing troops could only barely maintain it, and if they really had to draw away part of the backbone force, the consequences would be unimaginable.

Now that the city gates are in an emergency, Lu Zhao is also lacking in skills, just to deal with the state army in the east, he is already overwhelmed, and he really can't spare the time to go to other city gates to supervise the battle.

At this time, Lu An volunteered and took the initiative to ask Lu Zhao: "Father, the child is willing to go to Ximen to supervise the battle on behalf of his father to strengthen the army." ”

Although each gate is guarded by a tooth keeper or captain, in the face of the fierce offensive of the Bingzhou army, these tooth generals or captains are naturally a little panicked because of their prestige and experience, or they are worried that they will not be able to hold it, and their subordinates may not have confidence in them, so it is urgent for Lu Zhao to go over to supervise the battle to stabilize the morale of the army.

But Lu An knew that the battle on the east gate side was the most intense, and it was all supported by Lu Zhao, and he couldn't spare the time to rush to help other places now, so Lu An took the initiative to ask for orders, hoping to go to the west gate to supervise the battle on behalf of Lu Zhao.

The West Gate has always been another focus of attack of the Bingzhou Army, and the battle situation at the East Gate is urgent, and it is estimated that the West Gate will not be any better, so Lu An took the lead in proposing to reinforce the West Gate.

Although Lu An is only a civilian position in the army, with this position, he can't suppress those wild soldiers, but he is also Lu Zhao's son, and with this heavy identity, he can obey.

Lu Zhao nodded, although in his opinion, this is not a good way, but is there a better way now? Since Lu An took the initiative to invite Ying to go, Lu Zhao agreed to him, and at the same time asked him to send 500 people from the old department in the city to the west gate.

Compared to such a large-scale war, 500 people may be a drop in the bucket, but it is better than nothing.

Lu An didn't say a word, gave his hand, got off the city, and went to the west gate.

Sending Lu An to the West Gate more or less relieved some of Lu Zhao's pressure, but on the south gate and the north gate, it was also necessary to send some big men to supervise the battle, so Lu An called Guo Hong, who was not engaged in Liang Dynasty and Wu Meng, and asked them to take 500 people to the south gate and the north gate to supervise the battle to ensure that the city was not lost.

The defensive battle of the city is like a bucket, no matter which plank fails, the bucket will leak, and the same is true of the city, no matter which one is lost, it will eventually lead to the fall of the city.

Therefore, in the defensive battle of the city, there is no such thing as favoring one over the other, the defense of any place is the key point, and there is no room for mistakes, and the weaker the link, the more attention must be paid to it, otherwise the consequences will be serious.

The all-out offensive of the Bingzhou army is obviously a signal, that is, the Bingzhou army can't wait, they are desperate, and they bet all their troops up, and they are completely in a hurry to jump over the wall. At this time, the more Lu Zhao is needed to deal with it calmly, he must not panic, let alone chaos, and must not give the state army any opportunity to take advantage of, as long as he gives the order and determination, and swears to fight to the death, he will definitely be able to hold the capital city.
