Shun Dynasty had weak national strength and barren land, and was almost at the verge of life and death. All the civil and military officials of the dynasty agreed to use troops against Li Xin. Li Zicheng decided to personally lead a 100,000 army to Kaizhou. Kaizhou was called Puyang in ancient times. It was located in the northeast of Henan and at the junction of Hebei, Shandong and Henan provinces. It has always been a place that military strategists must fight for.

Here, you can learn the news about Nanjing and Beijing as soon as possible and stop.

Ten days later, Hangzhou!

"Your Majesty, Li Zicheng has personally led a large army of 100,000 and headed towards Kaizhou!"

Liu Yuanbin, holding a whisk, stepped into the hall and bowed to salute.

"good!"

King Gui, who was sitting upright on the throne, said yes and looked at Zhu Youlang, who was sitting at the lower head.

King Gui appointed Zhu Youlang as the crown prince. Because of his poor health, Zhu Youlang was essentially in charge of the affairs of the court.

Zhu Youlang asked, "Dorgon has any movement?"

Liu Yuanbin said: "When I returned to the prince, there was no movement in the direction of Manchuria, but... Dorgon has never returned to Chenyang since he retreated to Jinzhou. He must have taken action against Ningyuan at any time."

"The Manchus are as cunning as foxes!"

Zhu Youlang cursed without angrily.

Hou Xun bowed and said, "Emperor, Li Xin is mobilizing troops and will go south at any time to attack Hangzhou. The emperor should make plans early."

Hangzhou is located north of Qiantang River. Li Xin attacked with an army. There was no need to cross the river. Zheng Zhilong's naval army could not be used.

Sun Chuanting couldn't help but look at Zheng Zhilong, and then said, "We should start the battle first. We will lead elite troops to attack Nanjing from both sides of the sea and land. We also ask the emperor to issue an edict to fight against rebellion!"

"good!"

King Gui nodded and looked at Zhu Youlang again.

Zhu Youlang instructed him to wait for the pen to be a writer, and there was no way. The princes of the Zhu family were usually raised as pigs, so they could not have good literary charm, and many of them were even illiterate. If they asked them to write edicts, it must be Gadigai, I, Dihaile and other lots of Fengyang dialects, which made them laugh.

Hou Xun is worthy of being a veteran civil servant. He accused Li Xin of rebelling and abused Zhu Ming's royal family. He said that King Gui summoned the righteous and brave, and would vow to the Northern Expedition, and called on heroes from all over the world to fight against Li Xin together!

Three days later, Sun Chuanting led 30,000 troops out of Hangzhou to march towards Nanjing. The main force was Zheng Zhilong's fleet, with 500 warships of all sizes and 1,000 ships of various types, and the Qiantang River was storming and advanced to Nanjing through the estuary of the Yangtze River.

Those who accompanied Zheng Zhilong were Zheng Sen, Ma Shiying, Lu Xiangxian and other important figures.

Three days later, on the Qiantang River, there were films of sails. After a drum sounded, each ship sailed towards the Qiantang River mouth in turn.

Ma Shiying stood on the tower and sighed: "I have only heard that when the eunuchs of the Three Treasures went to the West, there was no grand occasion for a while. Seeing this today, I really know that this is true. With this hero, I believe that the thief will be spared. Jinghai Hou, I will congratulate you first."

Everyone was stunned and did not expect that Ma Shiying was so shameless.

Zheng Zhilong laughed: "Mabutang is too famous, and Li Xin is also an extraordinary person. He has never fought. It is still difficult to determine the outcome of this battle!"

Although this statement is humble, it actually implies heroism. Zheng Zhilong has never considered the issue of failure. After all, he has been on the sea for decades, has the largest fleet in East Asia, equipped with thousands of red cannons. This is not all imitation of red cannons, but quite a few are the latest cannons purchased from the Dutch and Spanish.

More powerful and longer range.

His ship, Neptune, was 70 meters long and had three layers of deck. It was equipped with more than 50 cannons. Its firepower was extremely strong. Moreover, some ships in his fleet used Western technology, hung soft sails, and the artillery was mainly installed on the side, which was completely in line with the mainstream Western battle-style queuing style at that time.

Seeing his father stroking his beard and nodding with a smile, Zheng Sen couldn't help but persuade: "Father, I heard that Li Xin is good at using water mines and floating in the water, and he is elusive. My father must be careful! "

Zheng Zhilong waved his hand and said, "I already have a solution, so there is no need to be afraid of him!"

He left the Qiantang River estuary, detoured the Songjiang River, and then went up the Yangtze River to Nanjing. It was about 1,200 miles. Before Zheng Zhilong's fleet arrived in Songjiang, Li Xin received the news and ordered Zhang Quan to lead his army of 20,000 to Lishui County, southwest of Nanjing, to block Sun Chuanting from heading north.

Lishui has been the southeastern gateway to Nanjing since ancient times. From Lishui to Liyang and Yixing, there are many mountainous and hilly areas, making it easy to use the terrain to set up ambush.

He personally led the main force to station in Mufu Mountain.

Mufu Mountain is located on the south bank of the Yangtze River. It is about ten miles long and 800 meters wide. The main peak is nearly 200 meters high. The river surface at the foot of the mountain is between the modern Nanjing Yangtze River Second Bridge and Baguazhou. It has a width of two to two to five kilometers. Type 117 field artillery on the top of the mountain can block most of the river surface.

The soldiers pushed artillery up the rugged mountain road day and night, and many enthusiastic people volunteered to serve to help transport ammunition, food, water and various supplies.

For a moment, the foot of the Mufu Mountain was extremely busy.

Five days later, Huang Hai suddenly said, "Here you come!"

In the river downstream, there is Baguazhou lying across the middle of the river. The river water is divided into two streams and passes around the continent. In the two streams, there are thousands of sails, with shadows and amazing momentum.

Zheng Sen put down his telescope and turned his head and said, "Father, Li Xin has a large number of artillery on Mushan Mansion, and our army must pass as quickly as possible."

There are both advantages and disadvantages when placing the cannons on the deck. The advantage is that they can fully utilize the firepower on the side. After all, the fire speed of the cannons was slow and the accuracy was poor. Especially on bumpy boats, it would be great to have two or three hits of ten rounds. Therefore, loading the cannons into the sideways under the deck can make full use of the ship space and load the cannons to the greatest extent, increasing the power of concentrated fire.

However, the disadvantages are also obvious. The elevation angle is limited and cannot be shot to a high place. Therefore, the warship passes through the foot of the Shogun Mountain and will be in a situation where you cannot fight back when you are beaten. Even if some old-fashioned warships put artillery on the deck, they can only fire one shot at the Shogun Mountain at most. If you hit it or not, it will be left to fate.

"Yeah~~"

Zheng Zhilong nodded: "Li Xin has a tight defense and issuing orders to use a minesweeping ship to open the way!"

"Get orders!"

Someone waved the flag.

The so-called minesweeper is designed specifically for mines. A row of wooden fences are installed in front of an ordinary boat, about two to three zhang long and are spread in a fan shape. A minesweeper can cover a three zhang channel.

The Bandits had used mines in the Grand Canal, which was no secret, so Zheng Sen had this reminder. Zheng Zhilong also expected that Li Xin would inevitably lay mines in the river, so he prepared a minesweeper ship in advance to open the way.

Seeing the minesweeping ships sailing in front of the formation, there were hundreds of ships, Huang Hai couldn't help but say, "Commander-in-Chief, it seems that Zheng Zhilong is prepared. His ship may be able to control the mines. Should he release the mines?"

"The original plan remains unchanged!"

Li Xin said without hesitation.

"Get orders!"

People in the Yellow Sea waved the flag to the foot of the mountain.

One by one, one by one, strikingly rushing towards the fishing boats moored on the shore upstream. There were a total of 500 mine-burning boats, all of which were small fishing boats.

The ships quickly rowed into the river, and gradually floated downstream according to the staggered surface of the river. The mines today are no longer the most primitive wooden box square mines, but iron-shelled round mines, with better sealing properties, stronger wind and wave resistance, and greater explosion power.

In addition to floating lightning, the army has also developed a considerable number of anchor lightnings, which are fixed to a certain water depth through cables. The anchor lightning in the modern sense has the function of automatic depth setting and can control the depth of mine layout. The anchor lightning of the bandit army is not yet reached for the time being. Only the stupidest method can be used to understand the water situation in advance, draw a topographic map of the river bottom, and deploy anchor lightnings of different depths according to the terrain during wartime according to the coordinates.

Fortunately, the area where the mines were needed was only a section of the river at the foot of the Shogfu Mountains. After continuous exploration, we roughly understood the situation at the bottom of the river.

At present, the army is concentrating manpower and material resources to develop an electrolyte trigger device. Each antenna is composed of a zinc cup, a carbon rod and a glass tube containing an electrolyte. The antenna is equivalent to a dry battery, and the zinc cup is equivalent to the zinc skin on the outer layer of the battery. The carbon rod is similar to the carbon core with a copper head on the top of the battery. The electrolyte in the glass tube plays the role of a viscous body in the battery.

When the tentacles are bent, the glass tube breaks, and the electrolyte flows between the zinc cup and the carbon rod, a chemical reaction occurs, and the current is generated, and the current passes to the lightning officer, which detonates and detonates the water mine.

The reliability is not very strong for the time being, but once the research and development is successful, the sensitivity of the tentacles will be greatly improved, which can almost guarantee that it is about to break out.

Li Xin did not believe that Zheng Zhilong would not consider the mine factor, so he ordered great efforts to develop anchor mines. The floating lightning only plays a role in covering people's ears. The real killer weapon is anchor mines, but since it can only be placed at fixed locations, the mine-burning ship must slowly row downstream to leave room for mine-burning. Each ship is equipped with a topographic map at the bottom of the river to mark the depth of the water.
