The location of Dingzhou is very important. It is located in the central part of Hebei, and it is close to Taihang Mountain and Jingxing is not far away, which can connect to Bingzhou. The prince is in charge of Dingzhou and supervising the state, which not only facilitates the transportation of grain, grass and equipment in the eastern part of Guanlonghe, Hebei and Henan, but also makes it easier to pay attention to the situation in the southern part of Daibei desert.

After all, there is Xue Yantuo in Mobei.

"Then I'll go to Dingzhou."

But Lao Niu pulled Qin Lang and refused to let go, "The prince is still on the way to Dingzhou. Now the saint ordered Xiao Yu, Li Jing to take charge of Chang'an, Fang Xuanling, Wei Zheng to take charge of Luoyang. The prince went to Dingzhou to supervise the country, Ma Zhou and Li Daliang to assist. You happened to be in Dengzhou and brought so many people with you, so I'll do me a favor first."

"What are you doing?"

"I'm going to take advantage of the opportunity to take down Jian'an City, and you can take the formation for me."

Jian'an City is located to the west of Beisha City, between Beisha and Anshi City, and is also close to the sea, very close to Changdao. This city is not small, especially after the Goguryeo people lost Beisha before, they had to strengthen the defense of Jian'an City and increase their troops.

"Uncle Niu, if I were willing to fight, wouldn't I come back soon?"

"I don't care about you. Your Uncle Niu asked you for a favor, and you would be embarrassed to push yourself and stop it?"

"But the saint asked someone to assist the prince in charge of the country, and I also want to rush to marry the princess."

"Don't worry, it won't delay your business. It won't take long to fight Jian'an City. When the sea takes Jian'an City, I will ask Jianhu to send you to Tianjin to log in in person. How about it?"

Qin Lang saw that Lao Niu was so helpless, and there was no way.

"Okay, but I'm a little curious. Since you are the chief marching officer of the Pyongyang Road, shouldn't you lead the navy to Pyongyang? Why do you fight west instead?"

Lao Niu smiled, "Sanlang, aren't you laughing at me? Although I am the chief of the navy, the purpose of the water and land forces is to defeat Goguryeo. Now there are major operations on land, so of course I have to cooperate with them first. Lao Cheng is about to raid Tongding. At this time, I am also restraining the forces of the Goguryeo people."

"When I take down Jian'an, I will threaten Anshi again. As for Pyongyang, what's the rush?"

Lao Niu is worthy of being a veteran. He knows that the Navy is a partial teacher, and if he goes to fight Pyongyang alone, it will definitely not work. Fighting Pyongyang is only a restraint of the Goguryeo people. In the current situation, how can we directly surround Jian'an? The attack on An City is more direct and effective?

"Sanlang, can you lend me the thunder that you seized Beisha City?"

Qin Lang thought for a while, "I have given this thing to the saint long ago. The imperial court has a Shenji camp and a firearm prison. There must be a lot of things, but they are all with the saints. If you want to use it, you have to ask the saint to speak. It's useless to speak to me. I don't care about these things now, and I don't have them in my hands."

At that time, Qin Lang was so dangerous that the mountain city was so big, but Qin Lang could easily attack it with a light army. Niu Jinda remembered clearly that he had guarded Beisha for many years and knew even more that if he used ordinary tactics to capture such a ten-mile mountain city, how many people and elites would be dispatched to force it to seize it.

Jian'an City is not as dangerous as low sand, but Anshi City is not weaker than low sand.

Lao Niu not only wanted to capture Jian'an, but also wanted to capture Anshi City, but his troops were limited. Even if he had the 80,000 troops brought by Qin Lang, it was not the best way to attack and fight. He still wanted to use Qin Lang's method of seizing Beisha and miss the mysterious heavenly thunder.

However, Qin Lang had already dedicated this thing to the court. In fact, when he attacked Beisha City, the gunpowder he brought was carried by the Shenji Camp. The Shenji Camp was a secret firearm unit. It has been upgraded to the Shenji Army this morning. It is one of the ten armies of the Emperor's Northern Yamen. It is very mysterious. Anyway, the only ones in the Northern Yamen are open to the Eighth Army, and the Shenji Army belongs to the secret army.

This time Li Shimin personally conquered Liaodong, and the Shenji Army must have been in charge.

Qin Lang didn't know how far the Divine Machinery Army and Firearms have developed. He had secretly managed this mysterious unit for the emperor before, but he had stayed in Guangnan in recent years.

The old cow stroked his beard and was a little disappointed.

He also fantasized about getting such a secret and powerful thunder, and then he sent an elite force to attack Jian'an and An City, and a thunder fell.

Qin Lang didn't want to fight again, but Lao Niu didn't let go when he caught him.

Now the old Niu Xiaoniu two men are holding Qin Lang’s arm, just not letting him get off the boat.

Qin Lang has no choice but to meet such a scoundrel. They are all their own people. If other people dare to act like this, Qin Lang would have turned against him, but who would have made this a ox?

He didn't have gunpowder in his hands. Although he had a recipe, he had to have the amount of a strong city, which was not as simple as making a firecracker.

The old Niu kept leaving Qin Lang's side and followed Qin Lang a boat. On the same day, he asked his son Niu Jianhu to drive the 80,000 people away from Penglai Island and headed towards the opposite Liaonan Peninsula along the Miaodao Island Island.

The fleet sailed into Lushun Port.

When I came last time, I was still a territory of Goguryeo. It has been ten years in a blink of an eye and it has developed very prosperously. As a military port of the Beiyang Navy's Bohai Fleet, Lushun Port is indeed managed firmly. Not to mention the many ships in the port, even those watchtowers and castles, we can also know how much energy has been invested here over the years.

In contrast, although Dalian Port, which is a little more lively, is not so strict. It is a trading port. Although the Tang Dynasty only controlled the tip of the southern Liaoning Peninsula after Qin Lang took over Beisha, and it has never moved further north.

However, after all, the Haidong countries surrendered to the Tang Dynasty in recent years, and the maritime trade between the two sides was also very prosperous, and the trade volume increased year by year. Dalian, as the last port on the Tang Dynasty's Bohai route, was naturally very prosperous.

In recent years, the smuggling on the Bohai route has become more and more popular.

"As soon as this route stops, my place will be deserted. I have to kill Goguryeo as soon as possible, otherwise my Jinzhou will be declining." Lao Niu pointed to the harbor road filled with warships and transport ships.

The Tang Dynasty had been preparing for the expedition of Liao. In recent years, major shipyards on the southeast coast had received a large number of orders for warships, combat ships, transport ships, etc. Every year, the Tang Dynasty conquered Liaodong. Many ships were built in the Yangtze River inland shipyards, and some were even built in Bashu. In the future, they went down the river and went to sea to recruit the southern sailors of Jianghuai Ling to gather in the Donglai Peninsula, a naval base.

Those ships are relatively not considered combat ships, at most they are troop ships. They can sail along the coast and cross the East China Sea when the waves are calm, but they are definitely not as good as those of these new-style sea ships today.

Combat ships with various functions, including troop transport ships, grain transport ships, etc.

"Sanlang, I will give you this important command task." Lao Niu was very unkind.

Qin Lang refused, but Lao Niu was full of reasons, saying that you were reinstated, and you were the Chief Secretary and the Grand Marshal. You only have the highest official position and title here, so of course you have to be the leader, and you have brought the most soldiers.

Anyway, no matter what Qin Lang said, Lao Niu was like a scoundrel. At that time, he really wanted to kick Lao Niu into the sea.

Forced to board the pirate ship of Lao Niu and his son, the generals also asked Qin Lang to command, and he had no choice but to surrender.

A simple military discussion was held at the port to discuss combat plans.

Lao Niu's opinion was to cooperate with the offensive of Cheng Yaojin's main force, so he had to launch a surprise attack on Jian'an, restrain the forces of the Goguryeo people's south of the Liaodong defense line, and finally he could quickly capture Jian'an and then surround An City.

"The Goguryeo people along the Liaohe River have built a thousand-mile Great Wall in recent years and have managed it with the whole country. Not only has they added more than 100 large and large mountain cities on the basis of the original 100 large and small mountain cities, but they are also connected by city walls between the mountain cities, making this line of defense really strong."

"How many troops do they have?" Qin Lang asked.

"There are no less than 300,000 troops on the entire defense line, including 200,000 Great City Fortresses relying on Liaodong City and other Great Wall Defense Lines. In addition, there are about 100,000 troops on the second defense line in the rear. These 100,000 troops are considered mobile forces and can reinforce the front line at any time. It can also be used as the second interception if there is a gap in the front line."

"Just two lines of defense?"

"Of course not only. In Yalu River, the Goguryeo people also built a large fence along the river, which stretched for hundreds of miles. Yijiang built several fortresses and castles such as Pozhuo and Daxing. There were about 50,000 troops stationed. This is the last line of defense north of Pyongyang. If we can break through this line of defense, we can reach the city of Pyongyang."

Qin Lang said, "What if the navy rushed directly to the city of Pyongyang from the sea?"

"Of course this is OK, but Pyongyang is also very strong. They also built a small Chang'an city on the mountain, which is even more dangerous. Pyongyang City still has about 30,000 troops. In addition, Goguryeo and Baekje to the south have to consider. Japan has long reached an alliance. If we attack Pyongyang directly from the sea, we will not only have to attack the toughest, but also face the reinforcements from Yalushui and Baekje to the north and south. These reinforcements will be no less than 100,000."

Niu Jinda was not very interested in fighting Pyongyang directly. During the Sui Dynasty, Hu'er, Zhou Fashang and others led the navy to cross the sea to attack Pyongyang several times, and even entered Pyongyang City, but they were all defeated in the end, and they were still very badly, mainly because the navy was alone and had no help.

The closest success was that Yuwen Shu and others led nine armies to 300,000 troops to attack Pyongyang, which was less than 200 miles away from the navy at that time and would soon be in Pyongyang. However, in the end, the Nine Army was defeated, and the navy and land armies were defeated one by one, and they were defeated.

The biggest role of the navy's direct attack on Pyongyang is to restrain the enemy. It is too unrealistic to fantasize that the navy directly conquered Pyongyang to destroy Goguryeo, anyway, Lao Niu doesn't think so at all.

Lao Niu's plan was to cooperate with the main land force. Thanks to the Beisha City that Qin Lang raided, the Navy now has this base camp in southern Liaoning, and there is no need to struggle to attack. In recent years, it has reserved enough food, grass and weapons here and built many warships, not to mention that it can clearly grasp the deployment of the Goguryeo Army in southern Liaoning.
