At this time, resentment is Zheng Chenggong's primary emotion towards Wu Zheng.

If it weren't for Wu Zheng's rejection of his joint strategy Fujian, how could he have suffered such a big defeat?

Thinking of this, Zheng Chenggong said: "There is no need to send an envoy to Hangzhou Mansion, he can control the waters around Chen Qianshan, and this king can also control the coastal waters of Fujian and Guangdong." He may restrict my caravan from going north, and the king may restrict the passage of merchants from all his provinces...... According to the king's decree, from now on, all merchant ships flying the flag of the Northern Expeditionary Army shall not pass through the waters controlled by our army! ”

Chen Yonghua was shocked, he was really anxious, and hurriedly persuaded: "Lord Wang, such a-for-tat confrontation is afraid that it will lead to a war ......." ”

"Is this king still afraid that he won't succeed?" Zheng Chenggong glared and said, "He will be the first year of junior high school, and I will be the fifteenth, right and wrong, there are two sides of the court to negotiate...... You don't have to say any more, herald! ”

Chen Yonghua could only retreat.

However, before Chen Yonghua walked out of the door, a soldier came to report that Shi Lang had surrendered.

Shi Lang has fallen?

Hearing the news, Chen Yonghua turned around.

Shi Lang's troops are not large, which is not enough to affect the overall situation, but as soon as Shi Lang falls, then Haiyang City will become an isolated city, and there will be no reinforcements.

It happened to be a rare opportunity for the Zheng army to attack Haiyang City.

Chen Yonghua quickly turned around, bowed to Zheng Chenggong and said, "Heaven helps the prince conquer Haiyang and recover Chaozhou Mansion." ”

However, Zheng Chenggong still hesitated, he looked at Chen Yonghua and said: "Shi Lang is only more than 3,000 people, and Hao Shangjiu of Haiyang City has 6,000 defenders, sticking to the fortified city, and there are muskets, artillery and sharp weapons ....... ”

Chen Yonghua hurriedly said: "But at present, although our army has 20,000 people, it is stuck to a corner of Chaoyang, if we do not capture Haiyang and recover Chaozhou, once the Fujian Qing army goes south, our army can only retreat to the sea ......." ”

"Say no more!" Zheng Chenggong said in a low voice, "Since Shi Lang is willing to surrender, Hao Shangjiu is naturally willing to surrender, and now Haiyang City has become a lonely city, as long as the conditions are good, Hao Shangjiu will definitely surrender...... Send an envoy! ”

Chen Yonghua's face was gloomy and he retreated silently.

Watching Chen Yonghua leave, Zheng Chenggong's face became weird.

He picked up a page of letterhead pressed by several folded books from the side of his desk and read it again.

This is a letter from his uncle Zheng Zhiguan from Xiamen.

The letter also mentioned that the northern sea route was controlled by Wu Zheng, and almost all the merchant ships of the Zheng family going to Dagukou were blocked back.

The army's food and salaries were gone, and there was a possibility that the 8,000 garrisons and naval divisions in Xiamen might mutiny.

In desperation, Zheng Zhiguan could only return to the Zheng family's old business - robbery.

Not to mention, the results are remarkable.

Of course, Zheng Zhiguan's purpose in writing this letter was definitely not to report on the results of the looting of passing merchant ships.

Zheng Zhiguan's letter advised Zheng Chenggong to use the Zheng family's huge sailors to conduct a surprise attack on Wu Zheng's Zhoushan water division.

First, it was a warning to Wu Zheng and forced Wu Zheng to open up the sea route, at least so that the Zheng family's merchant fleet could continue to go north. Second, in order to repay Wang Deren's department was suddenly wiped out by Wu Zheng, which made the Zheng family lose a large monthly income.

Zheng Zhiguan's suggestion did make Zheng Chenggong hesitate.

Zheng Chenggong weighed in his heart, Zheng Zhiguan is not impossible, nor is Zheng Zhiguan arrogant.

The Zheng family has a huge sailor, although Zheng Zhilong surrendered to the Qing Dynasty, but Zheng Zhilong also had a small calculation, when he surrendered, only tens of thousands of infantry around him surrendered, and the rest of the army guarded the prefectures, and did not surrender at the same time.

Of course, after Zheng Zhilong surrendered, under the pressure of Duoduo, he gave the order to surrender, and after that, the Zheng army of the various provinces did surrender one after another.

But this does not include the sailors.

Duoduo didn't want to persecute too much, thinking that as long as the land was occupied, the Zheng family's sailors would be just rootless trees, which made sense, since ancient times, there had never been a sailor division that could insist on resisting after the fall of the country like the army.

This is because the naval division must have a base, no matter how powerful the naval division is, it also needs to be supplied from time to time, and if there are casualties, it also needs soldiers, and the coast is basically a place where there is no danger to defend, so the naval division, even if it is the navy of later generations, does not have the basis for independent resistance.

Duoduo's abacus was not wrong, and escorting Zheng Zhilong to Shuntian Mansion was tantamount to cutting off the room for resistance of the Zheng family's sailors, and it was only a matter of time before he surrendered.

But what Duoduo didn't expect was that the Zheng family had a Zheng Sen.

Several of Zheng Zhilong's brothers surrendered, but Zheng Zhilong's son refused to surrender.

Duoduo made a strategic mistake that after Zheng Zhilong surrendered, he should not have taken Zheng Zhilong to Shuntianfu.

If Zheng Zhilong is here, it will be a great suppression for Zheng Chenggong.

Even if Zheng Chenggong really wants to turn against Zheng Zhilong, with Zheng Zhilong's prestige in the army, how many Zheng Chengcheng will recruit?

But once Zheng Zhilong is escorted to Shuntian Mansion, well, the Zheng family in the entire land of Fujian and Guangdong is equal to a group of dragons without a leader, some descend to the Qing, some are independent, and some have voted for Yongli.

At this time, Zheng Chenggong suddenly ascended to the top and shouted, and naturally responded to the crowd.

Therefore, Zheng Chenggong's rise was very fast, far faster than Wu Zheng's in Shaoxing Mansion, because he recruited all the old Zheng family at the beginning, that is, they were all veterans, and they didn't even need training.

And the sailor is even more so, who wants to cross the ocean to the north and leave their homeland?

Since Zheng Chenggong is determined to resist the Qing Dynasty, he will naturally take effect.

And Duoduo made another strategic mistake at this time, if at this time, he poured all his efforts to launch a decisive battle against Zheng Chenggong against the Qing army of Fujian and Guangdong, it is very likely that Zheng Chenggong could only escape from the land and go to sea with the sailors.

But Duoduo didn't, he thought that Zheng Chenggong was nothing more than a problem of scabies, and it was no wonder that the Tartars who were about to win the world knew that in the next hundreds of years, it would be the world of the navy.

Duoduo not only did not encircle and suppress Zheng Chenggong, but instead sent troops north to attack Ningbo and Shaoxing.

This led to the great battle in Shaoxing Mansion, where the two sides invested a total of more than 100,000 people.

In that battle, Duoduo was captured and later executed, and Wu Zheng also lost Qian Sudian, a general.

And the biggest impact of this battle was that Zheng Chenggong's forces grew savagely and grew rapidly without any suppression.

At its peak, an army of 300,000 men had gathered.

This led to Zheng Chenggong sending people to Wu Zheng to seek a joint operation against Fujian, but after being rejected by Wu Zheng, he still insisted on attacking the battle of Fujian.

There was a great defeat outside the city of Fuzhou, and most of the troops were lost, so they had to lead the remnants to retreat to the south of Quanzhou and stick to the four coastal provinces of Fujian and Guangdong to recuperate.

But in this defeat, all the losses were infantry, and the Zheng Jiashui Division was still intact.

The Zheng family's sailors are very large, and there are too many large and small ships to count.

There were sixty-eight capital ships alone, loaded with forty-eight guns, two bow guns and two stern guns.

Medium-sized warships numbered more than three hundred, loaded with twenty-four or thirty-six guns.

The kind of small warships with eight or sixteen guns, arsonists, pike boats, etc., are even more difficult to count.
