The news of the defeat of the forbidden army spread to Chengwu City with the wind, and Cao Ren couldn't help but regret why he didn't send troops to the west to go farther, if he traveled ten miles more, he could let Li Dian and Gao Shun meet on a narrow road, and Li Dian and Yu Ban attacked together, not necessarily unable to defeat Gao Shun.

At this time, it was too late to think about what to regret, and Cao Ren could only devote all his energy to preparing for Yanbei's attack. It is said that most of the mission of defending March has been accomplished, but in fact, Yanbei has never made an offensive performance against Chengwu during this time, and now the camp outside the city has been uprooted, which means that Yanbei's eyes will eventually be on this city.

Only at this time did people know how much pressure Yu Ban had borne for Chengwu City before.

This reason lies in the fact that it was difficult for them to detect when they were in the forbidden camp, but when the forbidden camp disappeared, the generals were shocked to realize that Chengwu City was leaking everywhere and facing enemies on all sides.

Zhang Liaobu in the south did not know where he was, lurking in the shadows like poisonous snakes, and he would come out and give them a fatal blow at some point; Yanbei in the north is even more terrifying, the tiger lying on the low hill is already terrifying enough, but now this tiger has stood up and waved its claws to smash the forbidden camp, shaking its head and striding towards Chengwu City; To the northeast of them was Changyi, Shanyang County, and the defender Beiyan was not a famous general, but the thousands of soldiers and horses under his command were enough to block the road; As for the west side...... Previously, their only way to survive was to camp in the forbidden way.

At present, the forbidden army has been defeated, and the western transportation arteries have naturally fallen to the enemy.

"General, the enemy is coming!"

Soon after the scout reported the news, Cao Ren led the generals to the head of Chengwu City and looked north. Looking along the plain outside the city in the distance, the black slowly spread southward at the end of the eye, and in the shadows, the flag was obscured.

Dozens of thousand-strong army formations slowly advanced through the fields, and the cavalry wandering outside were lined up with the infantry formation with slow steps...... The momentum did not appear to be relaxed because of their slow march, but brought more pressure to Cao Ren and the others.

In military law, it is said that soldiers are noble and fast, but Yanbei's arrangement made Cao Ren feel how arrogant this only king with a different surname in the world was.

The confrontation lasted for two months, and the troops were sent out on one day, and the military fortress outside was removed, and the news was released that the city was attacked the next day, but the army appeared here one day later.

If it is replaced by other armies, it is probably due to the lack of control over the army and the loss of time. But for Yanbei, he is the expectation, he can attack the city whenever he wants.

"General, Yan Zhongqing has a stone cannon."

There is no need for others to talk too much, Cao Ren's eyes are not white on his face, dozens of thousands of people, and the huge black shadows at the forefront of the military array can be seen to be siege equipment. Cao Ren also knows very well what kind of 'gift' Yanbei will bring.

In the Yanbei front army, a whole hundred stone cannons slowly advanced under the control of tens of thousands of foot soldiers, the pace was slow but firm, and it was pushed straight to the foot of Chengwu City.

However, Cao Ren, who was at the head of the city, realized something even more terrifying, and he heard the scouts of his subordinates reporting it, "General, the enemy has been found in the south of the city, under the banner of Zhang Liao...... Zhang Liao is here! ”

Yanbei is terrible, everyone knows that he is terrible, so this emotion will only be in people's hearts and will not be spoken, and there will be no secondary transmission of fear. But Zhang Liao's name is different, some people are afraid that he is afraid to death, and some people are eager to fight him, so Zhang Zi Daqi can be rooted in the south of the city, and the defenders in the city are in chaos.

The long confrontation ended, and with the sound of horns outside the city, the Yanbei army began to attack the city!

Yanbei's subordinates did not set up camp, and directly and simply set up a stone cannon a hundred steps away from the city, and tens of thousands of soldiers operated stone cannons to transport boulders, accompanied by the sound of golden drums, hundreds of huge stone bullets flew into the north of Chengwu!

Many Cao army soldiers in the city who had never fought with the Yan clan's soldiers and horses still had the leisure to raise their hands and point to the distance where the Yan army had pierced the stone cannon, "Then the Yan army generals are stupid, so far away, even a strong bow may not be able to shoot into the city, let alone flying stones...... Flying Stones are coming! ”

Halfway through the joke, I saw those stone bullets shoot straight at them over an incredible distance of hundreds of paces!

Cao Ren originally wanted to command the defense at the head of the city, but he didn't want Yanbei to even say a word, and his subordinates didn't even tie up the camp and threw stone cannons at him, which scared him so much that he ran away, shouting loudly and letting the soldiers hide aside...... Hell, is there such a siege!

It was rumored in Cao's army that most of the cities that Zhang Liao had broken would not be occupied, so he would move so quickly for thousands of miles, and Cao Ren never understood what this was for. But when he saw the Yanbei Army attacking, he finally understood...... The walls are all smashed, and they occupy a fart!

Hundreds of huge boulders were blasted out by the stone cannons, and some flew down on the roofs of the houses in the city, and the beams could not support the huge force and were smashed down in a blink of an eye; Some rolled down the streets, smashing the rammed earth into a large pit and splashing stones for dozens of steps, destroying all the cattle, horses and men in their way, but nothing that was alive could stop them; More boulders smashed on the walls, causing the city to shake violently, and the defenders of the city were shaken to pieces, but it was lucky.

The real misfortune was the boulders that fell on the battlements...... Despite the fact that there were only a dozen stone bullets, they were accurate hits. The bluestone-rammed battlements were not enough to withstand such a strong attack, and they were smashed by the boulders almost defenselessly, and then the unabated boulders ran through the walls one flesh after another.

The Chengwu City garrisoned by Cao Ren is not strong, but he has a lot of soldiers, even if he does not have the 5,000 soldiers and horses of the forbidden department, there are still more than 20,000 defenders in the city, after all, Li Dian Lejin fled here with his troops. This was originally an advantage, but Cao Ren regretted it at this time.

What's the use of him asking for so many soldiers and preparing so many garrisons?

In just one round of stone artillery attack, more than a dozen stone bullets crushed the city, causing Cao Renbu to lose hundreds of soldiers, some of whom were directly hit by stone bullets and disappeared without a trace, and some were crushed and their hands and feet were crushed to the sky and the ground.

"All scattered, all scattered!"

The city gate tower has collapsed, and the soldiers are scattered and run down the city Cao Ren did not stop it, but just shouted loudly with his cronies to let them scatter and run, the city head is absolutely unable to stay, but there is no need to worry about Yanbei attacking the city head. As long as the brigade starts to climb the city, the stone cannon bombardment will definitely stop, and that is Cao Ren's chance. If the Yan army wants to directly collapse the city wall, there is no way...... Everything is left to fate, see if Yanbei will break the city in one day.

"Let the soldiers dig tunnels under the city, if the city walls can withstand today, this battle will still be fought. If you can't stand ......" Cao Ren let out a long breath, shook his head and said: "Street fighting, it's just a death." ”
