Luo Shixin attacked Liu Heimin's camp at night and had just returned to Lishui City. Chang He, the left general of the Xia army, and Gao Yaxian, the right general of the Xia army, commanded the army and stormed the city of Zhushui, without giving Luo Shixin's 500 soldiers a chance to breathe.

The sky was light, and the first wave of the Xia army's offensive began. 30,000 foot soldiers, under the cover of 20,000 crossbowmen, rushed to the bottom of the city with all their strength and filled the moat. The moat is the first barrier of the water city, which is more than three meters deep and more than five meters wide, because with the moat, the Xia army's ladders, battering rams and other large siege equipment cannot be used. In the thunderous sound of war drums, the strong bow and hard crossbow of the Xia soldiers exerted a powerful power, and the dense feather arrows blocked every battlement on the city wall, and the Tang army could not raise its head at all, so it could only occasionally push down a few rolling logs and rumble down, and the rolling logs rolled into the moat, but filled the moat for the Xia army. The 30,000 infantry of the Xia army were divided into three echelons, each team of 10,000 people, each in a group of two, carrying a basket of dirt, swooping down on the side of the moat, quickly pouring the soil into the moat, and then quickly returning. It rotated once for half an hour, and after two hours, the moat outside the city was filled in flat.

At noon, Chang He and Gao Yaxian ordered the whole army to rest, set up camps, do a good job of defense, and feast on war meals.

In the afternoon, the Xia army launched a second wave of onslaught.

Gao Yaxian, the right general of the Xia army, held a long sword and a helmet through armor, standing on a dirt slope a stone's throw away from the city and personally commanding the siege battle, while Chang He, the left general of the Xia army, held a sword in one hand and a shield in the other, and personally led the soldiers to charge in the front line.

In the vast field outside the city, people shouted and neighed, and the sound of drums and shouts shook the heavens and the earth. There are also continuous lights on the head of the city, the Tang army's helmet is bright, and everyone is brave. Luo Shixin had a large amount of pig and beef fat transported to the city, divided into clay pots, and placed them all next to the city wall. When the Xia army attacked, the Tang army, under the command of Luo Shixin, smashed the grease clay pot into the ladder of the Xia army. The grease clay pot exploded, and the pig and cow fat splashed on the body of the ladder and the Xia soldiers, and the butter torches that could burn for a long time were also thrown down from the city. Then a dense layer of rolling wood and stones rolled down from the city, smashing the ladder and smashing the Xia soldiers to death under the city wall. Although the Xia army had strong bows and crossbows, this kind of long-range weapon could not be used in the siege, otherwise it would accidentally injure its own soldiers. Moreover, no matter how many arrows there are, they are limited, and if they are shot out and cannot be recovered, how can they be shot indefinitely?

After attacking for two more hours, the Xia army was helpless against the water city. Gao Yaxian reluctantly ordered to stop the attack.

Chang He, the left general of the Xia Dynasty, who had been on the front line, leading the soldiers and desperately rushing to kill, limped to Gao Yaxian's side.

Gao Yaxian and Chang He are old brothers on the battlefield, seeing that Chang He was injured, Gao Yaxian hurriedly walked over and asked with concern: "Lao Chang, are you injured?" ”

Chang He replied with a big grin: "It's okay, when I climbed the ladder, I fell from it and fell." Go back and rest for two days and you'll be fine. ”

Gao Yaxian said: "It's okay, it's okay." Chang, you go back and rest first, here I am. ”

Chang He didn't leave, but asked Gao Yaxian: "Today's battle, Luo Shixin, it's not a waste of fame, he still has some skills." Lao Gao, look, what to do next? ”

Gao Yaxian said: "Then what else can I do? Luo Shixin has some skills, but there are few of them, only 500 people. There are a lot of us, and they can't bear to consume. Tonight, I will organize my men and horses to attack again. I don't believe that I can't take a small city in the water? ”

Chang He dissuaded: "Lao Gao, no." Don't you see anything in today's battle? ”

Gao Yaxian asked, "What do you see?" ”

Chang He said: "Luo Shixin only led 500 soldiers and horses to garrison the lonely city of Lishui, and there were no reinforcements. This is the Tang Dynasty, someone wants to put Luo Shixin to death. Luo Shixin is the favorite general of Li Shimin, the king of Qin, but he is the thorn in the eye of the prince Jiancheng and the king of Qi Yuanji. ”

Gao Yaxian immediately understood, and said: "Lao Chang, you mean to say that the generals of the Tang army are not in harmony, and we can take advantage of it." ”

Chang He nodded.

Gao Yaxian asked: "Lao Chang, you have a lot of ideas, you can say it quickly, how can you take advantage of the discord between the crown prince Jiancheng and the henchmen of Li Shimin, the king of Luoyang Qin, to fight this battle?" ”

Chang He said slowly: "For the water city, only storm it, not break the city." Encircled the point to send reinforcements, attracting other henchmen of Li Shimin, the king of Qin in Luoyang City, to come to the rescue, and then annihilate them one by one. The crown prince was built, and the king of Qi, Yuanji, would definitely be very happy to let those people come and send them to death. Annihilating them, we can not only expand the results of the war, but also make a name for ourselves. Luo Shixin and other cronies of Li Shimin, the king of Qin in Luoyang City, are all world-famous warriors. If they both died at the hands of our two brothers, wouldn't our two brothers be more famous than them? ”

Gao Yaxian's eyes lit up and said, "Lao Chang, this is a good idea." Let's do it. ”

On the second day, the sun had slowly risen into the sky, and Gao Yaxian slowly organized the soldiers to attack the city in a decent manner, and all the generals of the Xia Dynasty who participated in the attack were given a strict order by Gao Yaxian: only attack the city, not break the city. Whoever dares to break the city, come and see you. All the generals were stunned by this inexplicable military order, but they had to do it according to the military order. Liu Heimin, the king of Handong, was very strict with the military discipline on the battlefield, and no one was willing to take his head and violate the military order.

The handsome account of Liu Heimin, the king of Handong, Dong Kangmai, the secretary of the Xia Dynasty's military department, pointed to the army commanded by Chang He and Gao Yaxian, who were attacking on the front line, and complained: "Chang He and Gao Yaxian are also famous generals of my Xia army, how did they fight this battle?" The small city guarded by only 500 people did not come down for two consecutive days. Yesterday the day was very good, there was no night battle at night, today's battle does not have the momentum of yesterday, not to mention, now it is like a child playing at home, for fear of hurting Tang Jun, what are they doing? If they can't do it, Weichen hopes that the king of Handong can replace them, and some of the troops of my Xia Dynasty are strong generals. ”

Liu Heimin, the king of Handong, who was proficient in military affairs, smiled slightly and said: "Only attack the city, not break the city." Chang He and Gao Yaxian are putting long lines and catching big fish. Who do they want to fish? Who will take the bait? Tang Prince Li Jiancheng? Li Yuanji, King of Qi? Or is it the king of Henan and the eastern capital who stayed behind Li Daoxuan? ”

Hearing what Liu Heimin said, Dong Kangmai fell into deep thought.
