Kaifeng was the capital of the Northern Song Dynasty, and it was also the place where the King of Zhou was vassalized in the current court. Kaifeng was tall and deep. Moreover, the King of Zhou was also quite talented. He was not stingy with his family property. In addition to helping the victims, he also took out silver to reward the soldiers guarding the city. With such a prince, the people in the city naturally participated in the war enthusiastically and were willing to die for the King of Zhou.

In view of the shortcomings of Kaifeng City's urban defense, someone invented a city-defense weapon called Xuanlou.

Since ancient times, wars have been frequent in the Central Plains. When the ancients built city walls, a rectangular enemy platform protruded outward from the city wall at every distance, called the horse face. This design is to attack the enemy attacking the city from the side, thereby eliminating the blind spots of defense. In fact, it is equivalent to a Western prism.

However, there was no horse face in Kaifeng City. A scholar named Zhang Jian advised him to make a hanging building with thick wooden boards, protruding outside the city wall, one was distributed every few warheads, and several soldiers could enter the hanging building with fire pots, bows, arrows and gunstones to hit the thief soldiers who were chiseling the wall. Huang Shu, the advisor to guard the city, agreed with this plan, and ordered the craftsmen to successfully build fifty hanging buildings overnight and lay them on the city wall.

Li Guodong replied: "Kaifeng City is as solid as a golden soup. His Highness of the King of Zhou is kind and kind to save the victims. If the thieves come to attack, the soldiers and people in the city will inevitably share the same hatred of the enemy, and the thieves will definitely not be able to break Kaifeng. Therefore, what we will consider is that once the thieves cannot capture for a long time, they will inevitably dig open the Yellow River embankment and flood Kaifeng!"

As soon as this was said, everyone in the hall was shocked. The Yellow River in Kaifeng was more than three meters above the ground, and the height of the river bottom was two meters above Kaifeng. If Li Zicheng succeeded in this plan, then the ancient city of Kaifeng would be flooded by floods and all the soldiers and civilians in the city would become fish and turtles.

King Zhu Gongyi of Zhou was puzzled and confused: "Wuweibo, the thief is not to win people's hearts, saying that he only kills gentry but not harms the people? But if he spreads open the Yellow River embankment, he will suffer more than just the soldiers and civilians in Kaifeng City. King Zhou has caused trouble for hundreds of miles and harms millions of people. If he does this, will the people of the world no longer believe in him?"

Li Guodong said: "Your Highness, the way the thieves bribed the people is all the idea of ​​Li Yan, a military advisor of the thieves army. The thieves are not that kind. Even if they harm the people of Kaifeng, if there is a major disaster today, the thieves army will not worry about not being able to recruit refugees! If Henan suffers another flood, it will only create more victims, and those victims will become cannon fodders in the army again! But please rest assured that with me here, the thieves will not succeed!"

Huang Shu asked worriedly: "Wuweibo, you only have six or seven thousand troops. Can you stop the millions of thieves?"

Although Li Guodong didn't like Huang Shu, a traitor who later surrendered to the Qing Dynasty, he is still a minister of the Ming Dynasty and it is not easy to have any attacks. So he replied: "Don't worry, with Ben Bo's troops there, the thieves rest and step onto the river embankment!"

Chen Yongfu suddenly thought of something: "Wuweibo, the Yellow River is a river on the ground from Zhengzhou, and is more than 130 miles to Kaifeng, with only six or seven thousand people, can they guard the river embankment of a hundred miles?"

"Please rest assured, besides the seven thousand iron cavalry, I also have the help of the Huai Army Navy! If the bandit army attempts to open the river embankment, the navy can block the bandits. In addition, the seven thousand iron cavalry of this vassal can not only defend the river embankment, but also make the bandits afraid! You can imagine that if the bandit army attacks the city, there is a cavalry on the periphery that is eyeing the army, and the army will be unstable. When the bandits attack the city, they must be wary of our troops at all times. Therefore, as long as you block the bandits' army, the bandits will withdraw soon." Li Guodong replied.

King Zhu Gongye of Zhou was overjoyed: "The lives of the soldiers and civilians in Kaifeng City will be handed over to Wuweibo!"

The royal palace held a large banquet to invite Li Guodong and officials of all sizes in Kaifeng City. Li Guodong was concerned about the upcoming battle of Kaifeng and did not drink too much wine. For the Fu King of Luoyang, Li Guodong could not save him. After all, according to his knowledge that Li Zicheng captured Luoyang, he killed all the gentry officials and did not harm the people. However, Kaifeng was different. The kindness of King Zhou's heart made the military and civilians willing to defend the city for him. If Kaifeng City was broken, Li Zicheng would inevitably vent his anger at the people in the city, so Kaifeng had to save it.

Li Guodong returned to his camp where he had been on the river embankment, and saw his soldiers busy on the river embankment. A trench was dug in front of the river embankment, and a small hole was opened from the river embankment, which attracted some Yellow River water, filled the trench, forming a small river, and the slope of the river embankment was widening. His engineering troops also arrived, and they arrived by boat, with a total of 20,000 people.

Although these engineers did not undergo much tactical training, if they fought head-on with the bandit army, they would probably not be able to defeat the bandits. However, they were well-known in engineering construction. The engineers were good at building fortifications and using fortifications for defense. The engineers with more than 20,000 engineers could completely transform the Yellow River embankment into an unbreakable line of defense within three days. As long as there were Jinyang cavalry and engineer soldiers guarding the river embankment, no matter how many rebels were, they would not be able to attack.

In just three days, with the efforts of 20,000 engineers, behind the "moat" under the river embankment, fortresses built with sandbags and wooden piles appeared. This fortress was dug a hole underground and then drilled wooden piles. The outer periphery was covered with sandbags. It was a fortress group in front. Tiger squat cannons, turtledove-footed guns and other firearms that can fire shotguns were arranged in the sandbag fortress. Behind the fortress group, earth walls were built with rammed earth piles. The earth wall was not high, but there was also earth wall behind the earth wall. Relying on the upgrade of the river embankment, this kind of fortification formed three-dimensional multi-layer defensive fortifications.

The fortifications in front and back are complicated and intersecting each other, and the fortresses and fortresses echo each other. In the face of such a fortification group, it can be said that even if the number of the rebels is twice as large, they will not be able to take down Li Guodong's defense line.

The 30,000 cavalry of the King of Rebellion came out of Luoyang, and it took only three days and three nights to walk more than 400 miles from Luoyang to Kaifeng and came outside Kaifeng City.

"King of Chuang, Kaifeng's city is solid. If it is a strong attack, our army will suffer heavy losses. It depends on whether the people in the city are willing to help our army." Li Yan suggested.

Niu Jinxing sneered: "The city is full of unruly people. I have long been bribed by the government's pitiful benefits. Want them to help our army? Humph, it's impossible."

Li Zicheng looked at Kaifeng City in front of him and suddenly laughed: "Although Kaifeng's city is solid, it has no protruding horse face, and the city wall seems to have not been built for many years, so it can be dug. As long as our army attacks the city and digs the city bricks, a gap will be dug."

At this moment, the scouts and cavalry of the rebel army came to report: "Qi Bi Chuang King, there is a group of officers and soldiers stationed on the Yellow River embankment north of Kaifeng City! The number of people is unclear, and they are all hiding in the camp."

"Who is the soldier?" Li Zicheng asked.

"It seems that the Jinyang army from Shanxi is the men of Li Guodong, the man of Wuwei Bo."

"Li Guodong?" Li Zicheng remembered this name. Because this person is neither an enemy nor a friend, he is said to be an enemy, but when the peasant uprising army was besieged by Hequ, Li Guodong once helped the peasant army in the most difficult time; he was said to be a friend, he was also an officer and soldier of the court.

Niu Jinxing didn't know the relationship between Li Guodong and the peasant army, but he had heard of Li Guodong's power, so he stepped forward and said, "King of Chuang, this man's army is extremely fierce. Jiannu, who is said to be invincible, was defeated by him! This man fought against Jiannu and fought hundreds of battles in all major and large battles, but he had no results!"

"It's really amazing!" Li Zicheng nodded, "But I think it's better to send someone to this camp to see if he can persuade him to surrender to our army!"

"Please advise him to surrender to our army?" Niu Jinxing widened his eyes in surprise.

Liu Zongmin laughed: "King Jian Gaoming! If you send someone who is capable of speaking and knowledgeable, this person might submit to our army! Otherwise, this person will always be a big problem for our army to be stationed in the north of the city!"
