The cannon wall was in the shape of a horseshoe, and a vine basket filled with soil and logs formed a chest wall of more than six feet thick. A special ammunition depot was dug. A fence and horse-resisting resistors were erected in front of the chest wall, as well as a line of defense for the mecha gunners and spearmen. A large group of people could be placed between the cannon walls. If the battle was fought in the wilderness, the cannon wall could also cover the two wings of the brigade.

The cannon base not only contains siege cannons, but also four-pound cannons that protect the cannon base. It is a multi-purpose fortification. After checking, Li Mingxun was very satisfied with this.

Soon, Li Mingxun ordered artillery to enter the cannon base. There were six siege cannons in Li Mingxun's hand. Except for the two captured red cannons, the rest were eight-pound cannons. The eight-pound cannons came from Manila sailboats. The societies were not very interested in artillery of this caliber, because the societies ordered a batch of nine-pound cannons from the UK and set the caliber of the medium cannons at nine-pounds. Such artillery of different caliber is used as shore defense cannons and fortress cannons. Among the artillery owned in the North, the heaviest cannons that can be transported here is only eight-pound cannons.

Transporting artillery into the artillery position was a difficult task. Li Mingxun handed it to Taktu, and the large-scale drag of the horse attracted the counterattack of the Donglu. Dudu and Bolu personally led the cavalry out of Ningguta and attacked the artillery team. The number of cavalry reached 600. When they broke through the shotgun barrage shot from the artillery base, avoided the harassment of the cavalry, and dispersed the slaves pulling the artillery, they found that there was no muzzle to stuff gunpowder in it, and even destroying the artillery stand was useless, because these were just a few fakes with wood coated asphalt. Apart from killing more than a dozen slaves, the Donglu got nothing. Instead, dozens of elite cavalry died under the firepower of the club. Especially when they left the city and entered the city, the four-pound cannons that had entered the artillery base could aim and fire. It was difficult to find a good target such as a cavalry team gathered at the city gate on the battlefield.

The real artillery entered the cannon base that night. Taktu asked the coolie to clear two roads, pour boiling water on the ground, create two ice paths, and then put the heavy artillery on the ice boat. Except for the troubles when we got ashore, it was easy all the way. Dudu stood at the top of the city and watched the enemy work in the middle of the night. Even if he knew that it was not a fraud, he was unwilling to take risks again.

The next morning, Du Du walked up to the city wall with his heavy thighs. At this moment, he felt even heavier. He had just received the news that the island barracks had abnormal movements.

Dudu climbed the city tower and observed the situation opposite again. Just one night passed, there was another fence in front of the enemy's artillery tower, and dozens of large and small resisting horses. Coolie and slaves were waving pickaxes and shovels, extending the trenches. Between the two artillery towers, the traffic trenches, the cannon chariots, and the teams were moving in it. The piles of vine baskets were gathered from all directions, turning into fortifications that required the children of the Eight Banners to use their lives and blood to break.

Among them, the most obvious change is the position behind the two cannons. The slaves are piled up together with a cart on earth, stone and wood. Now a platform of twenty feet in radius has been formed, constantly increasing.

"What is that? What the hell are the thief doing?" Du Du couldn't help asking.

"Maybe it's the altar. The barbarians here have the habit of beheading and shocking before the war begins, and sacrifice to the gods at the same time." Boro said with a frown.

The Qunta gave a completely different answer: "Prince, Mr. Beizi, I think it's a fort."

"Battery? Didn't they already have two artillery bases? Our artillery has been tested. If you shoot down, you can only break a layer of soil bag outside the artillery base, and then it will be reinforced soon." Boro was a little puzzled.

The Quintama said worriedly: "This is the turret, which is different from the cannon. Beizi Ye and the Islander did not know the situation in our city. They don't have many artillery. They may collapse the city wall or may not be able to collapse. If it is the former, it will be a decisive battle between the enemy and us. If it is the latter, the enemy's turret will be useful." The Quintama said.

Du Du punched the female wall. He had already understood the meaning of the quasi-tower or explained the enemy's plan. This fort would definitely be built very high, at least higher than the city wall. The cannons on it could be bombarded from a high place. Considering that Ninggu Tower is just a small city with a circumference of more than one mile, except for the area protected by the northern city wall, the cannons on the fortress can attack the entire city. If burning bullets are used, the entire city will never have peace. When food, cotton clothes, and houses are burned, the Eight Banners can only go out of the city and use their heads to touch the enemy's fortifications and combs.

Whether this tactic is used depends on whether the city wall is collapsed and whether the enemy is interested in the city's wealth.

Of course, Li Mingxun was interested in the wealth in the city. The army of the community set out from Yongning City and Vladivostok and went a thousand miles to expedition. Three thousand men arrived at Ningguta, and the people ate and chewed horses, which cost a huge amount of money. If they seized an empty city or a scrap city, it would be a huge blow to the morale of the army. Everyone would hesitate whether to continue to attack the Donglu’s confidant land and continue this kind of loss-making business.

From the captured Donglu, Li Mingxun got a lot of information about Ningguta, which stored a large amount of food, cloth, and iron tools. Of course, the more valuable one was the taxes and fur paid by tribes in the Songhua River and Mudanjiang River. You should know that this is already the territory of the Haixi Jurchens, which is much richer than the East China Jurchens.

Of course, in addition to these, there are also a large number of horses, especially war horses. Although the war horses equipped by the white armored soldiers of the East are incomparable to the Andalusian horses seized last time, they are already rare good horses in the north. The club urgently needs to establish their own cavalry and also need more stallions.

Du Du's face turned pale. He had completely lost his initiative in this city defense battle. He originally thought that defending Ningguta would lead to reinforcements next year, but now it seems that the enemy will not give him a chance. Since he can't help it, he has to make the worst plan.

Suddenly, a few loud noises sounded from the enemy's cannon. Du Du instinctively lay on the ground. He heard a thunderous sound. The city wall under his feet trembled, and soil and stones kept splashing on his body. Du Du spitted, his mouth and nose were full of sulfur and dust. He got up and found smoke and dust everywhere, flesh and blood everywhere, and the soldiers screamed constantly.

Du Du poked his head out and found a shell hit outside the city wall. A spider-web-like crack appeared on the frozen wall. The broken soil kept peeling off and falling down. Du Du shook his head and heard the sound of people around him. It was Boro. His face was covered with blood and a wound was whispering.

"Prince Anping, the enemy is bombarding the female wall. I can't stand here anymore. Come with me to go down the city!" Boro shouted and pulled Dudu down.

As Boro said, the artillery of the community was bombarding the auxiliary parts of the city wall, female walls, towers, and city towers, destroying these buildings. When the city siege, the soldiers on it would be exposed to the muzzle. This move was especially common in the cold winter. Frozen blocks of earth and wood chips knocked away by shells were as lethal as stones. When the shells hit the female wall, people around them would often be injured by more than ten meters.

"Leave a few people on the city walls and let the group of Korean bird gunmen and archers go down quickly, and don't eat shells here." Du Du shouted loudly as he ran.

Dudu and Boluo stood close to the base of the wall, while the doctor on one side was treating the wound on Boluo's face. Dudu breathed a long sigh, and was still scared. That was the power of artillery. No matter what kind of warrior, he was the first Batulu of the Eight Banners, it was useless to wear triple armor.

The city wall behind him was under the rhythmic shelling of the enemy. Whenever he hit the female wall, a large number of stones would fly and dust would fill the sky. When the wall hit the city wall, the entire wall would tremble a few times. Experienced Du Du knew that this city wall, which was less than seven feet thick, could not withstand the bombardment of heavy artillery. If it weren't for the cold winter month and the wall was frozen and hard, it would have collapsed long ago.

"Call Bohetuo, I have something to say," Dudu shouted.

Boluo raised his head and glanced at his cousin. The anxiety revealed from his eyes he knew that Dudu had no hope for defending Ningguta.

Soon, Bohetuo ran over against the wall, and several people squatted in the corner and planned.

There was a rumbling sound of cannons in his ears, and dust kept splashing on his head. Several armored soldiers set up a simple tent with cowhide. Dudu, Junta, Bo and Tou brothers sat together. Dudu said: "You have seen the situation. The walls of Ningguta are unreliable. This war will be very difficult. I will make arrangements for some things early."

Bo and Tobo and Boluo were both serious, especially Bo and Tobo. He felt that Du Du seemed to be explaining his funeral. Du Du said: "I am the Prince of Anping of the Qing Dynasty. I was entrusted by the emperor to conquer the East China Sea. Now I can't even defend Ningguta. It is my duty to die here in battle. But Bo and Toboluo, you are the sons of Uncle Qi, my younger brothers, I can't watch you and me bury them together. Although the island barbarians are strong, they cannot kill the three grandsons of Lao Khan in one battle. Therefore, while the enemy has not yet siege the city, I need one of you to accept a task."

"I gave that man thirty cavalry and fifty horses. After leaving the city, I headed south to Huining, North Korea. We still had a group of people in the Mirror City Protectorate in North Korea. After we arrived, we sent a message to the court and urged the Koreans and the Eight Banners soldiers to go north to rescue. This was the only hope." Du Du said with difficulty.

Bo Hetuo showed joy on his face. Although it was a very risky thing to travel through Changbai Mountain to North Korea in this cold winter, the cold wind in winter was not as dangerous as the cruel East China Sea barbarians outside the city. Obviously, this is a way of life and a hope, which is better than staying in Ningguta and waiting to die.

"I'll go, I'll go." Bo and Tou blurted out.

Dudu glared at him and said, "Boheto, Boluo is your younger brother!"

Bohetuo knew that his actions did not conform to the tradition of brave dedication of the Aisin Gioro family, but he had already said it and could not retreat at this time. He hurriedly said: "Prince, isn't it the tradition of our Aisin Gioro family to stay as a young man?"

Dudu grabbed the whip and was about to beat it, but Boluo blocked it. Boluo said, "Let me go, a few of his servants follow the emperor. Ama conquers the East China Sea and is more familiar with it. He is more suitable than me."

"Okay, Bohetuo, you go and prepare. You must set out quickly and bring reinforcements. Your brother and I are here to wait for you to rescue!" Du Du said seriously.

Bohetuo stood up, patted the dust on his butt, and hurried to get his own things.

"The hopeless idiot has lost all the face of the Aisin Gioro family!" Du Du spat and cursed.

Boluo didn't say anything. Seeing his brother put on the thickest clothes, rode the strongest horse, led a horse full of dry food and tents, and left the city from the south gate with dozens of cavalry without even saying hello. When he was sad, Du Du suddenly patted his shoulder and said, "Boluo, you can clean up too and prepare to leave the city."

Boluo immediately stood up and bowed and bowed: "Are you going to counterattack the thief army?"

Du Du shook his head: "No, you clean up, I have prepared horses, dry food and guards for you. You set off immediately, leave Ninggu Tower, go straight west, follow our inn, and return to Shengjing."

"Prince Anping, are you?" Boluo was completely shocked. He had just arranged for his brother to ask for help from North Korea, so why did he arrange for him to ask for help from Shengjing? You must know that Ningguta is too far from Shengjing and thousands of miles away from Hetuara, so he will definitely not support reinforcements to arrive.

Du Du smiled and said, "You are better than your brother, and like my uncle seven, your father, you are the Optimus Prime of our Qing Dynasty. Bo Hetuo thought he had seized the opportunity to survive, but in fact, the mission to North Korea was just bait and temptation."

Du Du packed up his armor and said casually: "Boluo, Ningguta will definitely not be able to defend it. As the prince of the Qing Dynasty and the descendant of Aisin Gioro, all I can do is to let him play his final surplus value, send Bohe to North Korea, and save your life, bring this bag and hand it over to the emperor, and tell him the strength of our enemies."

The Quasi-Tao stuffed a bag into Boro's armor and pulled a good horse for him to ride. More than a dozen armored soldiers of the Red Flag came out of the city. Boro was jogging on the horse's back, recalling every arrangement and every sentence of Dudu, and finally understood the intention of his cousin.

As Du Du said, Ningguta could not be defended anymore. If Du Du was about to die here, he also needed an important person to report the situation about the enemy. The junta people were not suitable for it. Boluo, as a bei, had this ability. Du Du hoped that the Qing Dynasty would attach importance to enemies from the East, and Bohe To, who was sent to North Korea, was a test of Shen Qiyuan from Hamkyung's North Korea, in addition to covering Boluo's out of the city.

Du Du came to Ningguta and ordered Shen Qiyuan to fight together and send several waves of envoys. However, Shen Qiyuan was evasive due to his lack of troops and food, and sent Bo He Tuo to go there, and he could figure out Shen Qiyuan's power. If reinforcements were brought, Shen Qiyuan would be a loyal minister of the Qing Dynasty. If he could not bring them, even Bo He Tuo died in North Korea, then Shen Qiyuan would have a second intention.
