Zhao Bing watched the battle on a high slope three miles away from the city. During the entire shelling process, he seemed to bully people. The enemy did not organize a decent counterattack and was always in a passive situation of being beaten. However, due to the shielding of gunpowder, he could not see the current situation.

Speaking of which, this is also a problem that cannot be solved. At least he cannot solve it at present, because the combustion of black gunpowder will produce a large amount of smoke. The hundreds of cannons are fired in a volley, just like a sudden thick fog, and it is difficult to see the people within dozens of steps. The two sides of the "queuing and shooting" tactics have come closer and fire before firing, which is also inseparable from this.

As the city defense facilities were destroyed, in order to prevent accidental injury to the frontier infantry, the shelling of the Song army gradually weakened, and the situation on the battlefield was slowly reappeared in the lens of Zhao Bing's telescope. More than a dozen trench vehicles quickly approached the moat under the guidance of the soldiers and were pushed into the moat. As the tightened ropes were cut off, the folded bridge board was lowered and placed on the other side, a simple crossing bridge was successfully built.

As the Song army's artillery weakened, the enemy went back to the city, repaired the damaged city defenses, and carried supplies. The enemy troops under the city, who survived the artillery fire, used the broken sheep and horse walls as cover to shoot arrows at the Song army that built the bridge, trying to stop them from crossing the trenches. The Song army suppressed the rapid-fire cannons, fired against them across the trenches with muskets, and covered the bridge.

The open space in front of the city, which was dozens of steps wide, became a Shura Field for a time. To send siege equipment to the city, it was necessary to eliminate the enemy behind the Sheep and Horse Wall. The gap in weapons made it difficult for the enemy guarding the Sheep and Horse Wall to resist, but they still fought to the death and launched several counterattacks to destroy the Song army's trench chariots, but they would never wait for them to rush forward, and they would be killed or injured.

However, the Yuan army seemed to be invincible and could not kill them, and the counterattacking forces did not decrease, and there were still more and more forces. They continued to increase their troops through the secret doors dug by the city walls, and continued to attack the Song army that was passing through the trench. The Song army counterattacked with grenades and muskets, and even launched hand-to-hand combat in some areas.

The follow-up troops of the Song army continued to cross the trench, and the enemy's casualties were increasing, making it difficult to stop the Song army from passing by. The positions under the city finally changed hands. As the trench bridge was built, the siege began to begin. When the battle was the most critical time, the most urgent task was to break through the city gate or break the tall and thick city walls. As long as the city wall collapsed or a gap appeared, the attacking army could rush in. There was no danger to defend the defending side, and it was a matter of time before the defeat.

In the past, heavy weapons were also required to break through the city wall, which could be roughly divided into close-range direct damage type and long-range throwing type. Siege weapons are mainly made of wood and are accompanied by the basic leverage principle to throw out heavy objects such as stones. With the development of Song armies, siege weapons have also evolved to be mainly artillery.

The close-range direct destruction equipment is represented by the siege cone. The siege cone is a blunt weapon used to hit the city gate and city wall to destroy the enemy city and thus achieve victory in siege. It is usually fixed on a four-wheeler by a huge pile, and it uses huge inertia to hit the city wall or city gate through the pile head. After breaking through the first level of the city gate, soldiers will rush up to attack and destroy the fragile second level of the city gate.

In this era, stone throwers are the most effective long-range siege weapon, but the efficiency is low, you need to first install trenchers around the city, and shoot burning objects day and night to bombard the city walls. At the same time, the sledgehammers on the siege car constantly hit the city gate until they are knocked open or destroyed.

If the attacking party wants to climb to the city head, it needs to establish a solid forward position on the city wall. In many literary descriptions and film and television dramas, the attacking city adopts the method of placing ladders on the city wall and climbing up. In fact, it is okay to attack some small cities, but it is obviously not possible to attack some slightly larger cities.

Because the bearing capacity of the ladder is limited and the length is limited, the defenders only need to push the ladder with two poles against the ladder and push it over. Therefore, it is unreliable to use ladders to climb the city tower. The ladder commonly used in ancient siege was actually a cloud ladder with wheels at the bottom, which can be moved, and the ladder body can be moved up and down, and it is carried and lifted by humans to lean against the city wall.

During the Tang Dynasty, the main body of the ladder body was fixed, which shortened the time for ladder building. When siege, the ladder body was parked under the city wall and added a movable "upside the city ladder" to attack the city. It was called "Flying Cloud Ladder". The bottom was "a large wood as the bed and six wheels were placed under it", thus reducing the danger of ladder building and avoiding damage from enemy forces.

The structure of the ladder during the Song Dynasty had greater changes. The ladder adopted a folding ladder body, and the bottom of the ladder added protective facilities, which reduced the danger of the ladder body when siegeing the city and increased the stability of the ladder. However, the ladder was gradually abandoned due to its bulkiness, and there were rushing vehicles, with a height of more than ten meters, which could be level with or above the city wall. It was equipped with skin at the bottom to withstand the shooting of crossbows. It was equipped with overpasses and could be directly placed on the opponent's city wall, so that the attacking soldiers could easily rush into the opponent's team.

The enemy in front of the city was defeated and fled to both sides. The Song army also established a defense line, and several rushers were pushed out from the formation and crossed the trench bridge and headed towards the city gate along the opened road. At this time, a change occurred again. Suddenly, countless flying stones in the city crossed the city wall and smashed towards the siege team in front of the city.

"Stone-throwing machine!" Zhao Bing frowned when he saw this, which was a bit unexpected.

The defender usually arranges stone throwers on the city walls to kill and kill enemies who attack the city from a long range. In addition to throwing stones, they can also throw logs, metal and other heavy objects, or use ropes, cotton threads, etc. to dip them in oil and wrap them on the stones, ignite them and throw them to the enemy camp to burn and kill the enemy. They are considered the most powerful long-range weapon before the artillery appears.

"Your Majesty, it seems that there are people in the city who are good at using troops. They actually thought of hiding the stone throwing machine in the city and deceived the spy's eyes!" Xu Wulai, who was beside him, "Before the war, the spy saw many earthen platforms built by the ring road near the city wall. He felt strange. He once asked the people in the city that it was used for New Year's worship of gods and rituals."

"They believed it and didn't investigate it carefully?" Zhao Bing said with some amusement.

"The spy also came close to see it. The curtains were set up on the earthen platform, and the high platform was decorated with lights. I didn't find a stone thrower hidden. The stone thrower was not small and difficult to drag on it. So I just treated it as an interesting thing, but I didn't expect that there was a murderous intent in it." Xu Wunan sighed.

"Didn't the lookout notice?" Zhao Bing watched Feishi fall into the attacking team, and many soldiers were smashed. Two rushing cars were damaged and stopped. He saw that he became a living target and was ignited by the rockets shot from the city, losing his ability to attack.

"From the current situation, the enemy in the city took advantage of the darkness of the night to dismantle the stone thrower and transport it up, assembled the shrill ones, and then covered it up, and escaped the surveillance of the watchtower." Xu Wunan analyzed, "But as long as they activated it, they would expose their targets and would not escape the attack of our army's artillery fire."

‘Boom, boom, boom…’ Sure enough, as soon as the words were finished, the Song army launched artillery again, and rockets roared over the city wall to cover and shoot, suppressing the enemy’s stone throwing machine. The Weiyuan artillery quickly moved forward, raised the guns to shoot into the city, and carried out targets with the correction of the watchtower to attack the target at a fixed point. The mortars belonging to the assault forces in the front shell bombarded the enemy on the top of the city, killing and injuring the defending enemy, and covering the infantry to continue advancing.

"Master Lu!"

"Why is Lu Xiangsheng not in the camp? He is also coming to the front!" Zhao Bing turned around and saw that Lu Xiufu, with the help of two personal guards, also climbed up the high slope and hurriedly greeted him.

"Your Majesty is here in person, and the soldiers are rushing to death in blood. How dare I sit alone in the camp!" Lu Xiufu said while bowing.

"It's a big wind here, please come here!" Zhao Bing saw that his face was not good, and knew that he was still dissatisfied with leaving Handan without authorization and "coercing" the generals to breach the contract and went to the front line. He hurriedly smiled and helped him sit in the tent next to him.

"Your Majesty is a man of a thousand gold medal. In the past, we were scarce and we were the generals. It would be fine if our Majesty led the army to fight in person. Now our dynasty has millions of elite soldiers and generals. Forget it, we will still face the attack in person. If there is any mistake, I will let you die!" Lu Xiufu sat on Hu's bed and said with a fierce and white face.

"Prime Minister Lu is the pillar of the country. I will never be able to live a long life!" Lu Xiufu has always been respectful and acted steadily. Now he is shaking his face in person. Zhao Bing knew that he was really annoyed and quickly smiled.

"Your Majesty, ah..." Lu Xiufu was speechless when he saw His Majesty's smile, and sighed, "Your Majesty is not a foolish king. There is no need to say much about the truth in it. It is so good before leaving that he has repeatedly told him not to let His Majesty stay away from the battlefield, but now he doesn't have to make things difficult for me!"

"Okay, I won't say it, and Lu Prime Minister will not know it!" Zhao Bing agreed repeatedly, but laughed softly.

"His Majesty……"

"I will listen carefully to the next time, but now the war is at an important time, let's watch the battle first!" Zhao Bing didn't understand whether Lu was old or what, and he said more than before, and he kept nagging endlessly, so he quickly stuffed the telescope in his hand to him.

Sure enough, Lu Xiufu was quickly attracted by the fierce battle in front of him. He was also a soldier. Seeing that the enemy in the city refused to take the shelling and fought to the death. Arrows were like locusts, rolling wood and stones were smashed like rain to prevent the Song army from approaching the city wall. Whenever the Song army was repelled, the follow-up troops came forward to continue the attack. Both sides suffered heavy casualties. He looked for a moment and frowned:

"General Sun is also a general of many battles. Why is this battle incorrect? Knowing that our troops are inferior to those of the defending enemy, how can we concentrate our troops in one place to attack, and fight with the enemy repeatedly without hesitation, but we do not divide the troops to attack other places to disperse the enemy's forces!"
