Aocang County, the closest city to Zezhou in the area controlled by the Boling Wang clan in the western part of Laizhou.

Since the Boling Wang clan marched into Zezhou but failed miserably, the Wang clan sent a large number of men and horses to garrison the county seat of Aocang, the closest to Zezhou, to prevent the Yun clan from attacking on a large scale.

In the next two years, Wang's rebuilt the county seat of Aocang, heightened and strengthened the city wall, and sent additional troops to build the county seat into a military fortress, and the garrison in the county seat of Aocang County was as high as 30,000 people, accounting for almost half of the troops in Wang's hands.

In the winter of the fourth year of Tiancheng last year, the Wang clan noticed that the Yun clan army in Zezhou on the opposite side was frequently mobilized, and the Yun clan transported a large number of materials to Helin County, obviously the Yun clan was ready to make a move, and the atmosphere in Aocang County was also tense, and the battle more than two years ago cast a shadow on the hearts of many people, and they could not be relieved for a long time.

On the twenty-third day of the first lunar month, the Yun army was divided into four routes, with Shi Mincai, Lin Zhe, Yun Zhuo, and Yun Jing as the commanders of the four-way army, pointing at the two states of Laihe.

On the afternoon of the twenty-fifth day of the first lunar month, Shi Mincai led the First Infantry Division of the Yunjia Army and the First Brigade of the Temporary Urban Defense Army to ten miles south of Aocang County, where they temporarily camped for one night and fought again on the second day.

That night, the Wang army in the city of Aocang County sent several small groups of cavalry to attack the Yun army, but they were easily repelled by the Yun family army who were keeping vigil, and the losses were negligible.

In the early morning of the twenty-sixth day of the first lunar month, the Yun army, which had recovered its strength after resting all night, continued to march towards Aocang County after breakfast.

In the distance, the county seat of Aocang was heavily guarded, and the defenders of the county seat of Aocang knew that the Yun army was coming, and they were ready to defend the county seat of Aocang and block the Yun army.

Although there were 30,000 Wang troops stationed in Aocang County, and only 18,000 Yun troops came from afar, Wang Teng, who was born in Wang's family, knew in his heart that the Yun army was equipped with an incredible weapon that could shoot the enemy at a range far beyond the range of bows and arrows.

Therefore, Wang Teng could only choose to stick to Aocang County, and could not rely on the advantage of troops to go out of the city to fight.

"It would be great if our Wang clan also had those weapons, no North King and Nanyun would be our opponents." Wang Teng, who was standing on the city wall and looking at the south, sighed in his heart, but this idea was difficult to succeed, and the Wang family had also recruited the disciples of the Mo family to imitate the early equipment of the Yun family army from somewhere.

At the end of the day, 18,000 Yun clan's army surrounded the county seat of Aocang County, Shi Mincai sent a messenger to persuade the defenders of Aocang County to surrender, Wang Teng refused without hesitation, and wanted to resist to the end.

"Drums! Attack! Shi Min ordered calmly.

Boom! Boom! Boom!

After more than a dozen breaths, the war drums representing the attack sounded, and all the artillery guns in the Yun family army with enough range fired in unison at this moment, but none of the firearms fired bullets.

Rumble! Rumble! Rumble!

The flowering bullets fell on the city wall and exploded directly, the fragments of the shells scattered and flew in all directions, and more than a dozen solid bullets flew towards the two city gates in the north and south of Aocang County, directly smashing the city gates out of holes the size of more than a dozen human heads until the city gates were broken.

One round of shells, two rounds of shells, three rounds of shells.

Three rounds of shells poured down into the county seat of Aocang, but they did not cause much damage to the defenders of Aocang County, and even after the two city gates in the north and south of Aocang County were broken, they saw that behind the city gates was thick soil.

Wang Teng clearly understands the power of the Yun family's army equipped with firearms, and there are many introductions to the way the Yun family army fights in the information collected by the major families before, Wang Teng summed up the methods to fight against the Yun army: first, no body parts can be exposed on the city wall; Second, when the Yun army did not launch a charge and only shot from a distance, the soldiers on the city wall had to be in the corner to prevent being attacked; Third, use a large amount of soil to block the north and south gates (there are only two gates in the county); Four......

In the end, there was a situation where the Yunjia army bombarded but did not get too many results.

Shi Mincai didn't care about this situation, before the war began, many officers and generals of the Yun Family Army took this situation into account and figured out several ways to crack it.

Explosives packs of explosive weapons appear.

It is worth mentioning that with the industrial development of Yun's, the gunpowder used by Yunjiajun has transitioned from black powder to yellow powder, yellow powder is picric acid (trinitrophenol), which is a yellow crystal, so it is called yellow powder, the power of yellow powder is greater than that of black powder, after the large-scale production of yellow powder, the black powder will be completely replaced, and the firearms equipped by Yunjiajun are greatly increased because of the use of yellow powder.

The fourth round of artillery shells of the Yunjia army was fired towards the county seat of Aocang, and at the same time, several warriors from each column of the Yunjia army on all sides of the county seat rushed out of the array with explosive bags and ran towards the county seat of Aocang.

The fourth round of shells ended, the fifth round of shells hit again, there were soldiers on the city wall of Aocang County and found that there were several enemies on the opposite side, and they reported this matter to Wang Teng, but Wang Teng didn't think that even if a few innate grandmasters came on the opposite side, there were four innate grandmasters in Aocang County.

Just more than ten minutes after the fifth round of shells smashed into Aocang County, the more than ten warriors in the Yun family army who rushed to Aocang County with explosive bags had already come to the city wall of Aocang County.

The next moment, the warriors stopped, "ignited" the explosives bag in their hands and threw it to the base of the city wall, after throwing the explosive bag, the warriors quickly turned around and ran, as fast as they could, they were not worried that the enemy on the city wall would shoot arrows at them, but that they were worried about being injured by the explosives bag.

Rumble! Rumble! Rumble! Rumble! Rumble!

After a few breaths, a series of more than a dozen earth-shattering loud noises came out.

At the moment when the explosive pack exploded, the defenders who were huddled in the corners of the city wall and hid dared to fly into the sky by themselves.

In fact, these defenders did fly into the sky, and the huge power generated by the explosion of the yellow powder explosive package directly blew up several city walls in Aocang County, revealing the buildings behind the city wall.

"The city is broken! The city is broken! ”

Wang Teng had just woken up from the impact of the explosive bag explosion when he heard the sound of "the city is broken", "the city is broken" means that the city has been broken by the enemy, but it can also refer to the broken city wall, no matter which one it is, it is a cruel thing to the current Aocang County.

"It's God who is angry, everyone kneel down and beg God to calm his anger."

Even because of the violent explosion of the explosive pack, some people mistakenly thought that God was angry, and directly knelt on the ground and begged God to calm his anger.
