Luo Zhaoyun knew that Lai Hu'er had the experience of commanding a navy and was good at water warfare. When he attacked Goguryeo, Lai Hu'er trained navy in Bohai Bay, Shandong. He had a lot of experience in water flow, wind direction, and warships.

So, this arduous task was handed over to Lai Hu'er to build warships, leaving part of it for the vanguard army to use, and then carried him to cross the Wei River, and went around to Wuzhangyuan, then went north to continue crossing the Wei River, directly behind the four cities in Yanhe River, and cut off the Tang army's retreat.

Chen Ling led his troops to attack towns, towns and pavilions south of the Wei River in Fufeng County, covering hundreds of miles of areas, becoming Dahua's control area.

Although there are no big cities, there are still many counties and towns. The national affairs of Dahua are conveyed in a timely manner, local people join the army, purchase grain, etc., which will weaken the influence of the Tang army in Fufeng County, and can be said to kill two birds with one stone.

More than ten days passed quickly, and Li Jiancheng's team was gathering on the east bank of the Wei River, and strategists and generals arrived one after another.

Li Daoxuan, Liu Hongji, Murong Luohu, Duan Zhixuan and others joined the army and waited for the prince's order.

"Everyone, according to the scout information, the Dahua army is building ships in Xi'an, and it seems that it will forcefully cross the river and then attack cities such as Wenyuan and Wenyang. It is not known that they will choose to land. However, there are only a few suitable places for the army to climb the beach, and most of the rest are steep mountains. Our army will pay close attention. Once we find that Dahua crossing the river, we can draw off the troops and attack them halfway." Li Jiancheng analyzed.

Liu Hongji looked a little haggard and had a clean face. He was captured in those days and was abused. His body became weaker. At this time, he said: "Your Highness, Luo Cheng used military strategies and used strange strategies. Now he is in charge of the army. This kind of military use will definitely continue to be used. Be careful that he has other tricks to deal with us."

Staffman Li Wengan said, "Yes, we suffered a loss in the last time the earthquake was in the face of food and grass. Unexpectedly, we were ambushed by the Dahua army, and 80,000 troops were almost trapped in the Xiong Pass. This time, we need to be more cautious."

Li Jiancheng said: "Our army defends along the river, using four cities as lines, echoing north and south, but the river water is dangerous. It has not been determined since ancient times and is easy to be smuggled and attacked at night. Therefore, my Highness has sent a lot of people to patrol along the river every day, guard against enemy attacks and tricks."

Li Wengan continued: "This time, the food and grass in the four cities are enough for a hundred thousand troops. If you use it for more than two months, you should be able to withstand it for a while."

Yu Wenying looked worried and expressed her concerns: "I am worried that Nan Youcheng and Chen Cangcheng will be difficult to save."

Li Jiancheng said: "Just stick to it and hold back the Dahua Army, so that it can be distracted and cannot cross the river and fight with all its strength."

………

The sunset was like fire, the sunset was full of sunset, and felt tents were scattered in the endless wilderness. Some soldiers in the camp were wrestling with their upper bodies. Many people were cheering for them. Some people took off their saddles and were drinking and feeding them, combing out the manes of the war horses, and some squatted in front of the stove pit to cook, while wisps of smoke rose up.

Luo Zhaoyun, with civil servants and military generals, began to patrol the camp and expressed his concern for the soldiers.

Wherever we went, the three armies were greatly encouraged and warmly welcomed them, shouting: Long live long live!

"Your Majesty, the army is strong and you can launch a strong attack at any time!" Hou Junji said beside Luo Zhaoyun.

Luo Zhaoyun nodded and said, "First take Nanyoucheng and let the new recruits practice. Your pioneer elite surround Chen Cangcheng so that they cannot go out to rescue them. We will defeat these cities one by one!"

"I understand." Hou Junji bowed and obeyed.

A few days later, two young generals, Xue Wanbei and Mai Mengcai, commanded 30,000 new troops and siege the Nanyou small town.

"Dongdongdongdongdongdong!"

The war drums were beating, the gongs were loud and the horns were roaring. The Dahua New Army was put into the battlefield, not only attacking the city and fighting, but also conducting practical training.

Soon, after the arrows confronted, the two soldiers staged an ancient siege battle. The new soldiers of Dahua climbed up the city like a tide, and fell down like ripe grapes, and were inevitably killed and injured.

In siege, the advantage will definitely be on the side of the city guarding, condescending and occupying the advantage of the territory.

Because of the high-quality and advanced weapons, catapults, urn bombs, etc., the Dahua Army suffered a lot, and weakened the gap between the advantages and disadvantages in some geographical advantages.

Half a day later, the corpses piled up under the city, and blood stained the moat red. As the strength of the Dahua army gradually increased, the situation of the Tang army defending the city was quite unoptimistic.

The Tang general who was responsible for guarding the Nanyou City was named Wu Yihan. He commanded the Tang army in the city and fought desperately, not listening to the persuasion outside the city, and ignored the letter of persuasion shot into the city.

"Persist, the prince is staring at us on the other side of the river, defending this city, and dragging down Dahua's troops, is to win the opportunity for the prince to break the enemy." Wu Yihan shouted, but he was quite loyal to his duties.

However, some deputy generals were dissatisfied, because the prince had obviously given up on Nanyoucheng and let them live or die, and would not send troops to rescue them. He would not let them retreat. He just carried it to the end, so as to consume the enemy's troops and finally ruined all the Tang troops in the city.

"Boom boom boom!"

The rushing car kept hitting the city gate, and the stone bullets of the catapult were also smashing the city buildings. The city was in a mess, but it still seemed insufficient to break the city.

At dusk, Dahua's soldiers retreated, and the city was covered with corpses and soldiers on both sides had them.

In this battle, each suffered casualties, about 46. Even though the Tang army relied on the city's advantage, the casualties accounted for more than 40%, about 50,000 or 6,000 people.

The next day, Dahua's troops changed into a group of new troops and continued to attack the city, and were still honing these new troops that had never been in actual combat.

However, most of this group of teams were composed of Hu people, who were quite brave and fierce, making the Tang army's city in danger.

This is not a big city, so it is limited in height and is relatively easy to attack. As more and more Dahua soldiers climbing over the city, the Tang army has already shown a trend of defensive collapse.

"Boom!"

Suddenly, the city gate was broken, and the soldiers outside the city rushed forward and rushed towards the Tang army's defense line at the city gate. They handed over the troops in a short time. The soldiers in front fell down, while the ones behind them stepped on the bodies without hesitation. Among them, a Modao camp in the new army was responsible for opening the way, holding the Modao sharp and unstoppable. Wherever the blade passed, the Tang soldiers fell down in waves.
