More than 100,000 soldiers have a great demand for logistics materials when they leave Tongguan, and taking the waterway can greatly increase the transportation volume, so as to ensure the needs of the front-line army.

Starting from Chang'an, through Guò Weishui, and then into the Yellow River, and finally after a short section of Luoshui, you can directly reach Luoyang City, by waterway transportation, a large number of materials in Chang'an, can be transported to Luoyang in a steady stream, the army by water, can also arrive in Luoyang faster, and the speed of the march will be fast on land.

To this end, Hua'an issued an order to let the soldiers of the baggage battalion build all kinds of warships and transport ships on the edge of Weishui on the outskirts of Chang'an, and required that these ships were neither big nor small, and could pass along the Weishui and the Yellow River.

For long-term considerations, Hua'an asked the baggage battalion to build as many ships as possible, after all, the Yellow River has always led to the North Sea, not only to capture Luoyang, even if it attacks Hebei in the future, it can also reach Liyang City by waterway as a big ship and waterway.

Liyang is only about 200 miles away from Yecheng, and the army can land from the waterway and approach the city of Yecheng within a few days, and the military rations and other materials in the rear can also be transported to Liyang through the Yellow River, so as to provide sufficient logistical support for the army attacking Yecheng.

If you take Liyang and continue downstream, you can enter Beihai all the way, and you can directly enter Liaodong along Beihai, so as to capture Liaodong by surprise.

In other words, as long as there are enough soldiers, horses and ships, Hua'an can control a large area along both sides of the Yellow River, and can even sneak attack remote areas such as Liaodong.

The baggage battalion was building various types of ships in an orderly manner, and the expansion of Chang'an City had already begun. In order to accommodate enough workshops, warehouses, streets, and other facilities, Chang'an City had to undergo a large-scale expansion.

Chang'an City is on the edge of Weishui, so the expansion can only be carried out in the other direction, along the west and north walls of Chang'an.

The enlarged Chang'an City was four times the size of the original city, and the scale was extremely large, but the progress of the project was extremely slow due to the large amount of work required to build the city wall and the need to use stones and clay to make it stronger. And the walls were not completed. The construction of the city's facilities was difficult, so Hua'an decided to reduce the thickness and height of the city walls, and only attach a layer of stones to the outer surface of the walls. The central part is completely replaced with dirt.

But that's it. The defense of Chang'an City will be greatly reduced. However, in Hua Anxin, his strength is strong enough. Attacking as defense is the best defense, if you rely on the thick walls to resist the enemy, then you are not far from destruction, and the reason why the city walls are built is only to facilitate the daily management of the city and resist the invasion of thieves.

#####

Just when the construction in the direction of Guanzhong was in full swing, in the direction of Liaodong, Murong Jun could no longer bear it and planned to send troops south.

In the mansion of King Yan in Longcheng, Murong Jun, King of Yan, and the main generals under his command, such as Murong Ke, Murong Ba, and Mu Yugen, began to discuss the matter of capturing Youzhou.

Murong Jun looked at the generals and said: "Generals, Ran Min is just a servant, he brazenly proclaimed himself emperor, and tried in vain to slaughter Liuyi, such evil thieves must be eradicated as much as possible, so as not to cause endless troubles." ”

"Second brother, give the order! I would like to be a pioneer. Murong Ba hurriedly clenched his fists and begged for his life.

"Your Majesty, with my 200,000 elite army, whether it is Shi Yuan or Ran Min, I am powerless to resist, and the north of the Yellow River can be broken." Mu Yugen even said a big thing.

Murong Ke waved his hand and said: "Second brother, I don't know the time to go south in an all-round way at this time, but our army can't always stay in Longcheng, it's better to take Youzhou first, occupy Jicheng, and then decide when to go south according to the shape of Yecheng. ”

When Murong Jun heard this, he nodded, and said: "Jicheng has been the capital of Yan since ancient times, and I have been a big Yan country for many years, and now, it is time to capture Youzhou and move the capital to Jicheng." ”

"Second brother, let me be the vanguard, I will definitely break through Jicheng in one fell swoop to show the strength of my Great Yan Kingdom." Murong Ba asked for help again.

Murong Jun nodded, and ordered loudly: "Fifth brother, you lead 20,000 elite soldiers as the vanguard, take the east road through the Tuhe River to approach Jicheng, Mu Yugen, you lead 50,000 troops to attack in the direction of Valley County on the west road, and this prince will lead the main army to take the middle road to meet you." ”

"I'll do as I was told." Murong Ba and Mu Yugen hurriedly clasped their fists to receive the order, and immediately turned around to prepare.

After the generals left, Murong Jun looked at Murong Ke and said softly: "Fourth brother, do you also think that our army can't capture the whole of Hebei?" ”

Murong Ke nodded, and Zhengse replied: "That's right, Shi Yuan and Ran Min both have hundreds of thousands of horses under their commands, and their strength cannot be underestimated, although our army has 200,000 elite soldiers, it is not dominant. ”

Seeing that what Murong Ke said was very reasonable, Murong Jun smiled and praised: "When my father was alive, he once said that among our brothers, the fourth brother is the smartest, and now it seems that it is really not bad at all, the talent of the fourth brother is indeed above the brother!" ”

Being praised by Murong Jun, Murong Ke not only did not feel excited, but had an inexplicable nervousness, after all, Murong Jun was already in the position of King Yan, if he was suspicious of himself, the consequences would be strict.

"The second brother is too modest, but my father did say so, he once told me to my face, saying that I have such wisdom and talent, and I must assist the second brother well and help the second brother establish a hegemony, so that my Murong family can win the Central Plains." Murong Ke said wittily.

Listening to Murong Ke's words, Murong Jun felt very comfortable, paused, and said: "My Murong family has a talent like the fourth brother, and he will definitely be able to win the Central Plains, hahaha!" He laughed.

Seeing that Murong Jun did not suspect his intentions, Murong Ke breathed a sigh of relief, and then made plans to help Murong Jun analyze the general trend of the world.

On the second day when Murong Jun decided to go south, Murong Ba's 20,000 vanguard elites left Longcheng and took the east road to Jicheng, the capital of Youzhou, to kill, and then, Mu Yugen's 50,000 troops also left, and took the west road to kill in the direction of Valley County.

Another day later, Murong Jun, the king of Yan, personally led the main army, and gathered with Murong Ke, Murong Ping and others, and marched along the road to Youzhou.

Before leaving, Murong Jun ordered the officials of Longcheng to immediately prepare for the relocation of the capital, as long as the direction of Jicheng was almost ready, they should immediately start moving the capital.

Murong Ba is the first warrior of the Yan Kingdom, his martial arts are extremely strong, and the 20,000 elite soldiers under his command are also the elite divisions of the battle, in the battle of the Eastern Expedition to Goguryeo, Murong Ba once relied on this army to kill the King of Goguryeo and fled in defeat.

At this moment, Murong Ba led 20,000 elite soldiers, serving as the vanguard task, in the face of Zhao's scattered troops, he was even more courageous, and after only one day of expedition, he successively captured several cities of Zhao State, and went deep into the territory of Zhao State for dozens of miles, completely controlled Liaoxi County, and stationed troops in Yangle City, ready to rest for a day, and continue to march.

In the west of the Mu Yu roots, also achieved brilliant results, Mu Yu Gen led 50,000 troops, the mighty march in the direction of Shanggu County, along the way Zhao soldiers, seeing that Mu Yu root is strong, did not dare to resist and fled and surrendered, Mu Yu Gen did not need to blow away to control most of the Beiping County.

The following day, Murong Ba's army and Mu Yugen's army entered Yanguo County at the same time, Mu Yugen captured Anle City in the north of Yanguo County, and Murong Ba attacked Lucheng in the middle of Yanguo County, and sent pioneers to erect pontoon bridges, preparing to cross the pontoon bridges and kill Jicheng.

The pontoon bridge was built in a few hours, and Murong Ba led his army to cross the pontoon bridge and kill Jicheng.

At this moment, defending Jicheng is Wang Wu, the assassin of Youzhou of Zhao State, with only more than 10,000 men and horses under his command, but Jicheng is the capital of Youzhou, which is a fortified city that is easy to defend and difficult to attack, so in the face of Murong Ba's 20,000 elite soldiers, Wang Wu is not afraid at all, and actively arranges to defend the city.

After Murong Ba led his 20,000 troops to Jicheng, he immediately launched a full-scale feint to test the defensive situation of Jicheng, and after a fierce siege, the Yan army lost hundreds of elite soldiers, but failed to attack the city wall.

Seeing that Jicheng was easy to defend and difficult to attack, and could not be captured immediately, Murong Ba gave up the siege and retreated more than ten miles, and then, while building various siege equipment, he reported to Murong Jun in the rear.

A few days later, the main army led by Murong Jun, the king of Yan, arrived at Wuzhong, and Wang Wu, the assassin of Youzhou in Zhao State, began to be afraid, after all, the main army led by Murong Jun was more than 100,000, and the more than 10,000 soldiers and horses under his command could not hold Jicheng no matter what.

Moreover, Xiangguo's reinforcements can't be counted on, after all, the war between Shi Yuan and Ran Min has entered a white-hot stage, and both sides will use the main forces to deal with each other, so they naturally have no energy and strength to deal with remote areas.

In order not to fall into the infamy of abandoning the city, Wang Wu asked his general Wang Tuo to lead 2,000 soldiers to defend Jicheng, while he himself led the main force to evacuate Jicheng and retreat to the south in the name of defending Lukou.

A few days later, the main army under the command of Murong Jun, the king of Yan, arrived under the city of Jicheng, and joined with Murong Ba's 20,000 vanguards, facing only 2,000 men and horses in Jicheng, Murong Jun felt that it was easy to take, in order to reduce unnecessary casualties, Murong Jun sent envoys into Jicheng under the construction of the strategists to persuade Wang Tuo to surrender.

The envoy of the Yan State entered Jicheng with Murong Jun's good intentions, but Wang Tuo, who was loyal to Shi Yuan, refused to surrender and beheaded the envoy of the Yan State.

Faced with Wang Tuo's rudeness, Murong Jun was furious and immediately ordered Murong Ba and Murong Ke to lead the main army to attack Jicheng.

Jicheng, which was only defended by 2,000 men and horses, how could it block Murong Jun's main army, and after only half an hour of attacking the city, Jicheng was broken by the Yan army. (To be continued......)
