The huge fleet led by Huang Yong deterred the Ayutthaya Kingdom and the Donghu Kingdom, and it took more than a month to complete the procurement and sign the trade agreement, and returned at the end of February.

The fleet entered the South China Sea and the East China Sea to unload all the way, and many ships reloaded and needed to transport goods to Tianjin, Wei, Shanhaiguan and other places to continue sailing.

In the past three years, the designated elimination of pirate gangs has achieved remarkable results, and after Liu Xiang, Zheng Zhilong, Li Guozhu and other pirates surrendered, the Daming Haijiang has been free of thieves for thousands of miles.

In the past, merchant ships had to pay a protection fee of 1,000 to 3,000 silver coins according to the size of their displacement, and they were able to obtain a green dragon flag issued by the dragon warrior sailor.

If the Qinglong Flag is hoisted in the area under the actual control of the "Red Banner Army" at sea, once it is robbed, the Longwu Navy Division will compensate 15 times the protection fee paid by the ship.

If the merchant ships coming and going to the sea do not fly the Qinglong flag, they have to ask for more blessings, and if they are unlucky and are discovered by the Longwu sailors, there is only one end, the ships and goods will be confiscated, and all the crew will be reformed through labor for three years.

At present, the merchant ships traveling between the Liaohai, the East China Sea, and the South China Sea are all flying the Yellow Dragon Flag and the Qinglong Flag, and the ships flying the Yellow Dragon Flag means that they are the own ships of the "Red Flag Army" system.

The ships flying the Qinglong Flag came from a variety of sources, not only from the Ming maritime merchants, but also some of them were even armed merchant ships of the Portuguese, Spanish, French, and Dutch.

Only by opening up can the economy be invigorated, the Ming Dynasty welcomes fair trade, and does not exclude the armed merchant ships of the Xiyi countries that come to trade, but they must obediently pay protection fees, otherwise ships, goods, and people must be detained.

Portugal and Spain went into decline and were more obedient, but the Dutch East India Company, relying on a lot of deck warships and many armed merchant ships, was not very willing, and secretly robbed the merchant ships of other countries flying the Qinglong flag several times.

Without saying a word, Long Wu Sailor compensated the shipowner according to fifteen times the sum insured, mobilized all forces to find the culprit, and finally locked down the warship from the East India Company.

Huang Yong, who had learned the news on his way home, had come to Shanhaiguan in mid-April to ask for instructions, and he was ready to teach the Dutch a painful lesson and plan to capture the city of Geranza.

After talking about the complete seizure of Taiwan Island and the annihilation or capture of the Dutch near the city of Geranza and the Spaniards entrenched in the port of Jilong, they naturally talked about Huang Yi and other American pioneers.

Huang Yong was also worried about the safety of the long-distance fleet, and he suggested that his brother go to Qingniwa Military Port to preside over the launching ceremony of the "Hanwang" sail battleship, and then go to Ryukyu to have a look.

It was too torturous to sit in Shanhaiguan, and Huang Han also wanted to go to sea to relax, and he was particularly interested in the three steam engine steamers with a displacement of about 200 tons that were launched with the "Hanwang".

In the plan, the steam engine steamer that has entered the experimental stage will go back and forth between Qingniwa and Tianjin Wei for sea trials, and the scientific research team will record the operation data with the ship to solve mechanical problems in time to facilitate updating and improvement.

Although he is familiar with the development path of ships and knows that steam engine ships are the only way, Huang Han, a traveler, is still inexplicably excited to learn such good news, if the Han people can enter the steam engine era nearly two hundred years in advance.

The sailors of the "Han Empire" drove the steam engine steamer against the sail warship of Xiyi, which was simply not a war, but a crush.

It is believed that ships with small displacement can be put to sea for sea trials, and it is believed that the construction of steam engine warships will begin in a year and a half, and in three or four years, a heat-driven all-weather fleet will be born.

Huang Han took seven disciples who were still studying by his side and Gu Jixiang, as well as about 1,000 teenagers who had just been selected for the guard camp at the end of last year, and rode the "Hanjiang Junwang", "Tiger's Nest City", and "Jiulitai" sail battleships to Qingniwakou, the main base of the Longwu Naval Division.

The trial date was set for the Dragon Boat Festival in May, and Wen Tiren, Xu Guangqi, Song Yingxing, Shen Cunli, Yang Yipeng, Kong Wenshi, Peng Jiawang, Zhao Shizhong, Gui Youguang and other officials, scientists, and master craftsmen were present to watch the ceremony.

The design and construction of the battleship "Hanwang" with a displacement of 3,000 tons and the three steam engine steamers for sea trials were all supported by the "Hanjiang University" and the "Hanhua University." Many college students who were about to graduate chose to intern at the Qingniwa Military Port.

Academician Xu Guangqi's body is still tough, he is as enthusiastic as a youth, and he often goes back and forth to "Seoul", "Tiger's Den City", and Qingni Valley.

Since Song Yingxing entered the "Red Flag Army" system, he has burst out with great enthusiasm for work, and has spent most of the year in the dockyard of the military port with the team to solve technical problems on the spot.

May 5, the twelfth year of Chongzhen, is destined to be recorded in the annals of history, with the huge roar of three steam engines, three smoking steamers sailed to Tianjin Wei, human civilization is about to enter the era of thermal power.

Having a strong navy was Huang Han's aspiration, and now that this goal was within reach, he boarded the new flagship of the Longwu Naval Division, the "Hanwang", with great interest.

More than a dozen sail battleships, such as the Hangang Gunwang, the Tiger's Nest Fortress, and the Guridae, surrounded the flagship and went to inspect the new territory of Jeju and the Ryukyu vassal states.

The reason why Huang Han followed the fleet to Ryukyu to inspect was because the returning fleet would come here for supplies, and he wanted to get good news as soon as possible.

Huang Yong, the commander of the Longwu Naval Division, also had an idea, he was going to see the situation, and if he couldn't see the return of the fleet sailing to the Americas for a few more days, he asked to postpone the attack on the island of Taiwan and lead more than a dozen first-class battleships across the Pacific Ocean to rush to the vicinity of the planned landing site in the Americas.

In fact, Huang Han and Huang Yong were too worried, and the voyage fleet was smooth sailing and fruitful.

At this time, the fleet returning from "Hanwei Castle" had sailed to the Ryukyus in the wind and waves, and in addition to the dozen or so merchant ships loaded with cargo, a full twenty Galen-type armed merchant ships with a displacement of between 500 and 800 tons had been added.

There were only seven battleships of the Longwu Naval Division escorted, and the nine-man regiment at the time of departure, including Wang Zheng, Xu Erjue, Huang Yi, Yu Fei, and so on, were all left, and only Shi Daxuan, who had the most experience in navigation, took the medical scientist Shen Langzhong to lead the team on the way home.

In late May, when the returning fleet arrived safely in the Ryukyus for supplies, they unexpectedly met the head of the family, Huang Han, and the 5,000 sailors, gunners, and scientific researchers were so excited that they couldn't cry.

After 13 months, 5,000 people returned from completing their mission, and more than 17,000 people remained in Central America to defend their territory.

Huang Han was also overjoyed, and he immediately met with Shi Daxuan, Shen Langzhong, and all the crew, and all the civilian, military and military generals and soldiers who sailed to the Americas were rewarded with official promotions.

Shi Daxuan was eager to go down in history and was not afraid of hard work, and said on the spot that he would continue to lead the team to "Hanwei City", asking for a large number of immigrants to be as many as possible, because there were too many resources on the vast fertile land of North and South America, and the hostile forces were too weak, so I was sorry for the favor of the heavens if I didn't take it.
