Flying stones rained down on the head of Caiyang City.

Su Fei couldn't understand how the Duliao army, which had been robbed of its banner overnight, had turned five stone cannons into countless numbers. At least fifty stone cannons bombarded the north of Caiyang City, and in an instant, the city gate tower, which had been smashed by a flying stone and was in danger of collapsing, completely collapsed, and the soldiers inside were crushed into pulp before they could shout. In fact, Su Fei didn't have time to understand how Jiang Jin got so many stone cannons, he was busy fleeing from the city, all the defenders, and fleeing from the city.

The flying stones swept away everything in the city, whether it was the gate tower or the battlements, all of which were smashed. After witnessing the wrestlers carrying the large shield being smashed out of the corner of the flying stone and twisting their arms into a terrible shape, no one dared to stay at the head of the city, and the defenders of the urn city fled in the direction of the south, the real northern wall.

If it was just a flying stone, it would not be enough to cause such a terrible effect, but it would be different with a sandalwood archer with extraordinary earthwork archery. The unique sandalwood bows of Sanhan, Goguryeo, and Lelang counties of the Han Dynasty were requisitioned by the Yan Zhao State for military funds for many years, and if the people there could offer a well-constructed sandalwood bow a year, they could even be exempted from all taxes, and if they could do more, they could get a few hundred rewards from the state capital...... Of course, usually no one wants to offer a third sandalwood bow.

In the Central Plains, the use of this long-range weapon is a privilege reserved for the best foot archers, with at least one stone of bow power to ensure that arrows can be projected up to 400 paces away, and with heavy arrows, the range will be reduced but the armor-covered enemy can still be killed and injured at the longest distance. Of course, the damage of archers to the armored enemy army is never pitiful, but how many enemies can really have armor in war? Jiang Jin's enemy is not a Yan Zhao warrior who is armed to the teeth!

A battalion of Tan archers based on the two zhang earthwork more than 100 steps away from the city, you can imagine how much pressure it will cause to the defenders.

At this time, the power of the fifty-six catapults used to increase the momentum is especially important, they are not the last straw that breaks the camel's back, but a whole bundle!

The ground shook and the mountains shook, and the flying stones smashed down on the defenders, but they did not stop, but continued to wreak havoc on the city at a slightly slower pace. Even if the offensive slows down, there are still more than 50 stone cannons bombarding the small urn city, which defender dares to step forward?

When Zhang Xiu was in Liangzhou, he was a county official, supervising prisoners to do chengdan, that is, supervising them to build city walls, and coincidentally, Caiyang City was also under his rule in the past, although he did not station troops here, but also repaired the city walls. He told Jiang Jin that the city was made of plywood rammed and rammed with side plugs, and it was difficult to collapse it by simply bombarding it with stone cannons, and it was impossible to follow Zhang Liao's practice of directly smashing down a city wall when he attacked Pei.

Zhang Liao is rich and rich, and it is not difficult for one hundred and fifty catapults to smash the small Peiguo County, even if it is used to attack Xiangyang. What's more, even if the urn city is smashed, there is still a city wall inside that they can't smash with stone cannons, which is not advisable. Zhang Xiu's suggestion was to intimidate the defenders so that they could not inflict casualties on the besieging army, and then use a ladder to send the foot soldiers up to the urn city, and fight the enemy in close quarters until street fighting.

Jiang Jin's hope is to attack directly, open the gap in the city wall and put the soldiers and horses in, while Zhang Xiu's suggestion is to draw attention from all directions, and the archers on the urn city will directly confront the enemy to attract attention, and the entire northern city wall will be led by the military marquis of various departments to build dozens of pontoon bridges to quickly send the soldiers and horses to the other side of the moat, that is, under the city, and attack the city with ladder ants.

This was the most deadly siege method in the siege, and most of the time it was only used by rebels who lacked siege methods. However, at this time, if there are infantry soldiers who take the lead in attacking the urn city, under the advantage of troops, the north city wall can become the first area to be captured.

Jiang Jin agreed to this tactic, and at the same time ordered Zhang Xiu to ride on the remaining three city gates, especially the south of the city, ready to fight the enemy army fleeing Caiyang. In his opinion, as long as he seized control of the north of the city, the defenders' fighting spirit would be largely shattered, and then a simple street battle would follow.

He has five times the strength of the enemy army, although the composition of the soldiers under his command is not as elite as that of the good family, but fight a good fight? He wasn't afraid of anyone!

The defenders of the city were empty, and the city was filled with the helpless wails of the wounded, who knew that their death was near, but they had no means to defend themselves, so they could only wait for the enemy to come to the city. The strong sergeants under the city carried the huge logs to the broken bridge, and some people waded under the bridge to erect wooden pillars that had been prepared for a long time, and the logs were set up in the position that originally belonged to the suspension bridge, and a simple passage was just built, and the impatient foot soldiers rushed to the bottom of the urn city with the ladder and put the ladder on the head of the city.

"The first person to climb the city will be the first to take credit, and the reward will be 100 gold! Fifty gold will be rewarded for the guard, fifty gold for the captain, and fifty gold for the one who beheads Ganning! ”

Jiang Jin's order was handed down, and every marquis, general, and team leader in the city shouted the order to their subordinates in a loud voice, and each climbed up, preparing for the most brutal battle to seize the city...... Either return to your hometown with honor, or die a guest in a foreign land!

When the first shouting soldier jumped up to the city, he was greeted by no surprise that Su Fei had already set up a defensive north city wall to shoot arrows, and in an instant, more than ten arrows shot towards the gap in the cloud ladder, and in the blink of an eye, he was tied into a hedgehog, and half of his body was suspended outside the city on his back, and then a big hand below pulled his body out of the city with a collar and threw it under the city, and more Liao troops rushed to the city.

Many boulders on the walls of the urn created shelter for the besieging army to hide from arrows, and gradually the besieging army used the boulders to return fire with arrows at the defenders of the northern wall. Arrows came and went, Jiang Jin waved his arm under the city, and the flag was waved behind him, and a team of soldiers who were familiar with water pushed the logs down the moat and then flew into the river, spelling out a rickety pontoon bridge, and more soldiers waded through the river, carrying the ladder to kill the city.

The defenders were so strong that they were even relieved that the flying stones had stopped, and then they heard the frightened shouts of the robes leaning against the city. Ladders were erected on the city, and some soldiers had time to push the boulders down and smash the ladders, but more defenders were not so lucky, and before they could destroy the ladders, they saw one by one the enemy troops like ghosts and spirits jumping up to the city, rushing to kill with swords and swords, and in a blink of an eye, the city head was plunged into a melee.

More and more defenders' attention was attracted by the Duliao army at the head of the city beside them, and it was inevitable that the pressure of the besieging army on the city of Wengcheng would be sharply reduced, and the city of Wengcheng would be completely captured, and the Duliao army even had the spare strength to organize crossbowmen on the city to counterattack and support the robe.

Seeing that the sun was waning, Su Fei had no other way, so he put down his knife with hatred and ordered: "Retreat from the city and go to the south of the city to fight the enemy in the streets!" ”
