In Zhangzhou Nanao, a huge naval battle is underway.

The two sides of the battle were the Ming navy led by Wang Yindu of the southeast and the Zheng Sen army holding high the banner of Jingnan.

Since raising the banner of rebellion, Zheng Senjun has developed very smoothly at the beginning. In a short period of time, it occupied Xiamen and Kinmen and other Fujian islands, and sent troops to attack the road, Quanzhou, Zhangzhou and other prefectures and counties successively occupied it.

At that time, Wang Yin went to Zhejiang with the main naval division to cooperate with Chen Yue to deal with the rebels, and Shi Lang and others, who remained in Fujian, were unable to face Zheng Sen's attack, and could only flee to Fuzhou after successive defeats.

During this period of time, there have been constant wars in Fujian, and the rebels have wantonly confiscated the property of the gentry and done a lot of evil things. However, a few months of tens of thousands of rebels was not enough to wipe out the entire gentry in Fujian, which is mountainous, watery, and forested, and there are still a large number of gentry living in the countryside.

After the rumor that the rebels were behind the King of Qi spread, many Fujian gentry hated Chen Yue, the king of Qi. Therefore, after Zheng Sen announced the martyrdom, there were many gentry who defected to Zheng Senjun and cooperated with him, but some gentry were too timid to cooperate with Zheng Senjun, and secretly provided money, food, and materials.

Therefore, with the help of the Fujian gentry, Zheng Sen's power expanded rapidly, and in just one or two months, his troops and territory expanded a lot.

But that was where his good fortune ended. After Chen Yue reorganized the rebel army, he immediately set out to deal with him.

Wang Yin led tens of thousands of sailors to float south and arrived in Fuzhou to join Lü Tai, and the army belonging to the imperial court in Fuzhou reached more than 80,000 people.

At this time, Jin Shenghuan, the general soldier of Jiangxi, was named the general of Pingnan by Chen Yue, and entered Fujian with 50,000 elite Jiangxi soldiers, approaching from Tingzhou to Zhangzhou, Quanzhou.

Jiangxi since Chen Yue commanded the army to defeat and kill Zhang Xianzhong, it has always been the base camp of the King of Qi, after recruiting the defeated soldiers of the Western Army, the entire Jiangxi reorganized army of two or three hundred thousand, and half of the 100,000 troops led by Chen Yue to the Northern Expedition were Jiangxi soldiers.

Even if Chen Yue transferred troops from Jiangxi several times, Jiangxi still maintained more than 100,000 troops all year round, which was the proof of Chen Yue's suppression of Nanjing. Although most of the elites were successively transferred by Chen Yue, after two years of training, the armor and weapons were complete, and there was no shortage of food and salary, and the combat power of the Jiangxi soldiers was still above most of the Ming army.

Jin Shenghuan, who led the troops this time, is also a fierce general, and he is extremely skilled in leading the troops. Under his command, 50,000 Jiangxi soldiers entered Fujian from Tingzhou, and then approached Zhangzhou, Quanzhou, step by step.

Along the way, all the gentry who colluded with Zheng Sen's rebels were eliminated, and the local defenders of the prefecture and county cities they passed through were all taken to the beginning, and then hundreds to 1,000 defenders were left to defend the city.

In this way, although the speed of marching down the road was very slow, all the places that passed through were under the strict control of the Ming army, and there was no room for Zheng Jiajun's activities.

At the same time, Chen Yue ordered Liu Neng to take Jinyiwei to fully cooperate with the counterinsurgency. And the secret agents of Jinyiwei are not comparable to the hastily established spy organizations such as the Tiandihui, under Liu Neng's all-out suppression, the five halls of the Tiandihui under Chen Yonghua suffered heavy losses, and the Tangkou organizations in various parts of Fujian were terminated one after another.

Jin Shenghuan led his troops to attack by land, and Wang Yin also led the naval army to start the action, and the warships of the naval division of the department were dispatched one after another and began to cruise along the coast of Fujian.

At sea, the ships of the two armies were in daily contact and fighting, and the battles at sea were extremely frequent. However, after every battle, the ships of the Zheng army were more defeated than victorious.

The reason is that the quality of Zheng Jun's ships is far inferior to that of Wang Yin's sailors.

After the defeat of Zheng Zhilong, most of the warships in Fujian fell into the hands of Wang Yin, together with the huge ships that originally belonged to the Dongfan Army, the fleet in Wang Yin's hands at this moment is second to none not to mention the coast of Daming, even in the whole of Asia.

There were as many as twenty-three imitation Western-style plywood Galen ships in the fleet, each loaded with at least dozens of cannons. Some of these Galen ships were captured from the Dutch, and most of them were built by shipyards all over Zhejiang according to the drawings of Galen ships drawn by Chen Yue, and the total number of Galen ships caused in the past three years is so much.

However, this Galen ship alone was an extremely large maritime force, and the total number of ships of the Spaniards in Luzon and the Dutch in the South Seas combined was probably not so much. Not to mention that there are nearly 100 three-masted ships and more than a dozen four-masted ships.

On the other hand, in Zheng Sen's hands, most of what he has are small fortune boats. Although the number of ships is far larger than that of Wang Yin, the actual combat power is far from the same. In fact, Zheng Sen can't be blamed for this, originally the main battleships of the Zheng family's naval division fell into the hands of Wang Yin, and Zheng Sen was only able to gather some two-masted dhows, most of them were wave-breaking ships, but there were only about a dozen real three-masted battleships.

Therefore, the difference in power also caused a one-sided crushing at sea. In the face of the attacking Ming giant ships, in the face of the crazy artillery fire of the Ming army, the small boats in Zheng Sen's hands were not enough to see at all.

In several battles on the sea surface of Quanzhou, Zheng Sen's fleet was defeated, and even ships that were more than twice the size of the Ming army's naval division were not the opponents of the Ming army.

The water war was not good, Zheng Sen knew that Kinmen and Xiamen could not be held at all, and Jin Shenghuan and his troops had approached Quanzhou, so Zheng Sen had no choice but to order to withdraw from Quanzhou and retreat in the direction of Zhangzhou and Chaozhou. And Chaozhou already belongs to Guangdong.

Regarding the retreat of the Zheng army, Wang Yin did not forcibly pursue, but carried out step by step in accordance with the formulated strategy of suppressing bandits.

He first ordered Jin Shenghuan to lead the infantry army from Quanzhou to Zhangzhou, and then waited for an opportunity to enter Chaozhou, Guangdong. At the same time, Wang Yin gave orders to the local troops in Guangdong, ordering them to attack the Zheng Sen rebels who had entered the country. As for Wang Yin himself, he led the sailors to conquer Kinmen and Xiamen, and then continued south to force Nanao Island, the base camp of the Zheng army.

On Nanao Island, Zheng Sen gathered all the forces in his hands, with more than 50,000 troops and nearly 1,000 ships of all kinds. He was determined to fight to the death with the Ming army in South Australia. Because if Nanao Island is lost again, Zheng Jiajun will really become a pirate.

In the face of the powerful imperial navy, Zheng Sen decided to follow the example of his father Zheng Zhilong's victory in Liaoluo Bay, and relied on the fireship attack to achieve victory. To this end, Zheng Sen relied on a generous reward to organize more than 5,000 death squads, who would carry out suicide attacks on the Ming army's sailors in fireboats.

However, Zheng Sen's experience at this time was far from being comparable to that of his father Zheng Zhilong, and he did not understand at all that during the Battle of Liuluo Bay, Zheng Zhilong attacked the Dutch fleet with dozens of times the superiority of troops. And now, not to mention dozens of times, there is no superiority in troops.

The strength of the Zheng family army was more than 50,000 and nearly 1,000 ships, while the naval division in Wang Yin's hands had more than 30,000 troops and more than 200 warships of all kinds. The forces of the two sides are almost the same, but the combat power of the warships is very different.

As soon as Zheng's fireships were dispatched, they were smashed by the Ming warships, and there were very few fireships that could get close to the Ming army's fleet, and they could not pose any threat at all.
