The herald spread Yuwenshu's order throughout the barracks, and everyone knew that the siege should begin, after all, there was no order to make food these days, and now there was a noon to make food, and if it was not assembled, who didn't know what it was going to do.

"No, second son, why are we going to start attacking the city as soon as we come to Yuwenshu?" Hou Junji asked.

"It's not that we came to him Yuwenshu to start attacking the city, but he originally planned to attack the city today, because the soldiers and horses from all the counties have arrived, and it's time to launch an offensive, whether we arrive or not, he will attack the city." The eldest grandson Wuji said that in Yuwenshu's eyes, they were not so important.

"The auxiliary machine is right, but today will not be a siege, or just a small-scale tentative siege, he did not attack the city a few days ago is not exactly waiting for the soldiers and horses of the counties to arrive, but to spend a few days to fill the moat of Hongnong Palace. Hongnong Palace is connected to the Yellow River in the north, and the water of the moat is drawn from the Yellow River, which is not as deep as the water and is still flowing, and it is impossible to fill it up without spending some time, and today it should only be a battle to fill the river. Li Shimin added that at least he was proficient in military affairs, although people in history can only be praised for his governance, but his military talent is also one of the best, otherwise he would not be able to defeat most of the Tang Dynasty.

"Yes, my subordinates have been taught." Although Hou Junji has a short temper and temperament, he still listens to what Li Shimin says, especially in military affairs, and he spares no effort to learn.

In time, a well-fed army began to assemble.

"Father, the army has been assembled, don't we really wait for General Lai'er to arrive?" After assembling the army, Yuwen Shi came to report that he was originally enjoying his leisurely life as a colt in Daxing City, but with such a great credit, how could Yu Wenshu not think about his son? Not only Yuwen Shi was called by him to gild, but even Yuwen Zhi and his son who only did illegal things were pulled by him to this Hongnong battlefield, so no matter what, his Yuwen family will always be the biggest beneficiary of this encirclement and suppression of Yang Xuangan.

"There's no need to wait, it's just a battle to fill the river, not a siege battle, and you don't need an army to protect your children. When the war is hot, coming to Hu'er to lead a large army to support, it will inevitably increase morale and also hit Yang Xuangan's morale. "Yuwenshu taught his son earnestly, although Yuwenshi and become a concubine are infinitely beautiful, and they will be clothed and eaten for a lifetime, but these are all in the case of the eternal prosperity of the Yuwen family, once the Yuwen family declines, then the horse without the background is not called a horse, then it is really a horse. Don't look at the fact that the Yuwen family is unusually favored now, but as long as the emperor says a word, such a favor will be withdrawn at any time, which is far less than his own power, so Yuwen Shu tried every means to make his sons become officials.

"Yes, the boy understands." Yu Wenshi said that it is impossible for him to grasp military power as a colt, but it is understandable to follow his Lao Tzu to mix military merits, so that he can only be regarded as an errand runner rather than a spoon, so that he can exploit some loopholes in the court.

"Go, go out with your father, and learn more." Yuwenshu put on his armor, took Yang Guangci's sword, and let Yuwenshi and follow him out. The plan in his heart is not only to let Yuwen Shi and others make military achievements, but also to cultivate them with important things, and when the Yuwen family is really reversed, at least a few people can take it out to fill the façade, otherwise even if he has a large army, it will be useless if he doesn't know how to use soldiers.

Seeing the assembled army, Yuwenshu didn't talk nonsense, and he didn't even need to mobilize the work, because in the hearts of all the soldiers, it was only a matter of time before he captured Hongnong Palace, so he directly ordered the army to fill the river.

The first wave of the army to fill the river is the people of Hongnong's own county, originally Yuwenshu did not arrange for the soldiers and horses of the army to go first, but Yang Zhiji volunteered to lead his men and horses to serve as the first wave of the river reclamation army, originally he didn't want to, but after all, Yang Xuangan took the Hongnong Palace, he was too guarded to escape his responsibility, and his troops were all locals, so it was suitable to serve as the vanguard of river reclamation.

With Yuwenshu's order, tens of thousands of soldiers carried a cart of dirt and followed behind the 10,000 shield soldiers discharged by Yuwenshu and slowly advanced, and they used their lives to fill the moat.

"King, the army of Yuwenshu is coming, and tens of thousands of troops are coming to the east gate." Zhao Huaiyi said to Yang Xuangan, who was inspecting the city wall, that since he took Hongnong Palace, in order to prevent Yuwenshu from suddenly attacking the city, Yang Xuangan came to inspect every day.

"Let's go, go with the king. You go and ask the county prince and Li Shangshu to come over. Yang Xuangan ordered the guards to rush to the east gate.

When Yang Xuangan rushed to the east city wall, he saw a group of people and horses on the opposite side slowly advancing.

"Oh no, the enemy wants to fill the moat! The archers are ready to wait until the enemy has reached range and then shoot me hard. "In addition to using archers to shoot and block, Yang Xuangan really has no good way to organize the reclamation of Yuwenshu's army, it's not that there is no good way, it's just that there is no suitable weapon in the city compared to bows and arrows.

The moat is generally wide, in order to prevent the enemy from directly building pontoon bridges to attack the city, and it can also condescendingly attack the enemy troops on the opposite bank from the city wall, and the enemy's counterattack often does not pose an effective threat to the defenders of the city. Of course, this threat refers to the threat of local bow and arrow harvesting, but does not include the threat of other weapons, such as trebuchets.

"Shoot! Shoot hard! As soon as Yang Zhiji's river-filling army arrived at the moat, Yang Xuangan ordered the archers to shoot, and tens of thousands of arrows fell from the sky, which seemed spectacular, but the lethality was limited, because of the role of Yuwenshu's 10,000 shield soldiers, blocking most of the bows and arrows, and only a few bows and arrows fell into the troops, of course, just these few arrows took the lives of hundreds of soldiers.

"Quick, fill the river." When the first wave of arrow rain had just passed, and the other party had no time to launch the second wave of arrow rain, Yang Zhiji immediately ordered the troops to quickly fill the river, and after filling it up, quickly hide behind the shield. Although the soldiers moved Xun Shu, they still couldn't match the speed of the second wave of arrow rain, and when the river reclamation army finished pouring the soil in their hands and was ready to return, the second wave of arrow rain poured down, bringing blood flowers. This time there were thousands of soldiers who were taken away, although so, but the sacrifice of more than 10,000 people in exchange for the effect is very small, because after all, Hongnong Palace is built according to the emperor's palace, the moat is deep and wide enough, and the water is alive, plus the arrival of the spring flood, the water is more urgent, although the water surface is calm, but the sediment is quickly washed away after being channeled in.

"Keep filling the river and throw the burden into it." Yang Zhiji saw that just pouring the sediment into it had no effect, so he simply asked the soldiers to throw the burden into it, and in this way, the effect was obviously much better.

"Withdraw, withdraw!" After all the soldiers threw the sediment in their hands into the moat, Yang Zhiji decisively waved his troops and retreated, so that the first wave of river filling was over. This wave of reclamation is only a few meters forward, and for a moat that is several meters deep and more than ten meters long, it will take several times to fill in a road. However, in this short period of time, Yang Zhiji threw down the corpses of more than 3,000 soldiers. It seems that it is not so easy to fill the river, and this is only under the condition that Yang Xuangan only has a bow and arrow.

"Damn, if only there were crossbows to defend the city, they would never be allowed to fill the river so easily, and there is not much stock of bows and arrows." Yang Xuan said with hatred.
