Due to the current productivity, the firearms that Ganchao can make, namely flintlock muskets, various bronze cannons and mortars.

With the current technology and craftsmanship level of Ganchao, we cannot create rifles and cannot upgrade the firearms, completely leaving Western countries behind.

This requires basic science and breakthroughs in chemistry, smelting, mathematics, lathes, special steel, etc., in order to improve the technology of firearm manufacturing.

At this time, Ganchao's technological level was probably only comparable to that of the West, and even slightly weaker.

Therefore, the weapons that Gao Huan can make now can basically be manufactured by Westerners as long as they are studied.

Now that the Netherlands colludes with the Qing court, if Gao Huan does not interfere, the Qing army will definitely improve its equipment and pose a threat to the Gan Dynasty.

After Gao Huan discussed with Li Yan, the cabinet, according to Gao Huan's intention, was preparing to attack the Tang Dynasty and contacted Luzon.

Time flies February, and Zhou Yanru leads the fleet back to Nanjing from Japan.

After Gao Huan learned the news, he was quite satisfied with the results of the navy's expedition to the Japanese pirates. However, Gao Jian, who ran to Japan and became a retainer of the Tokugawa family, which surprised Gao Huan.

At this time, after hearing the Guoan Department’s return, Gao Huan couldn’t help but frown, “Is he sure he changed his name to Matsuhira Kama and became the adopted son of Matsuhira family?”

"Reporting to Your Majesty, it's absolutely true. This time Zhou Yizheng negotiated with the Tokugawa shogunate, the representative of the Tokugawa family is Matsuhira Kama!" Pei Lun said.

Gao Huan nodded slightly and pondered for a while. The Matsuhei family was the Osanthus family of the Tokugawa Shogunate. Tokugawa Ieyasu used to be called Matsuhei Motoyasu.

This kid Gao Jian, who was a big prince, was inappropriate, and went to Japan to be the adopted son of the Songpin family, which really lost all the face of the Gao family.

"Your Majesty, do you want to take people to Japan with a low position?" Pei Lun asked in a low voice.

Gao Huan stroked his beard and shook his head, "Forget it, don't worry about him for the time being. Let's deal with this matter after I unified the world."

"I understand!" Pei Lun saluted and prepared to leave.

Gao Huan suddenly said, "By the way, find a doctor for Zhou Ge Lao and see him for his illness. Keep it more confidential and don't make everyone know."

Gao Huan knew everything about Zhou Yanru in Japan, and knew that Zhou Yanru was unfortunately infected with syphilis when he experienced the Japanese style.

After Gao Huan gave the order, he thoughtfully gave Zhou Yanru a three-month leave, asking him to receive treatment secretly, and instructed Zhou Yanru not to work in the Councillor if he was not sick.

At this time, Pei Lun retreated, and Xia Wanchun came to ask for a meeting again, "Your Majesty! The prince of Luzon has arrived in Beijing!"

Gao Huan raised his eyebrows and said happily: "Is Zheng Sen here? Arrange him to see me!"

Now that the Luzon State has recovered Luzon, Gao Huan hopes that the Zheng family can be transferred to Luzon Island and gradually hand over Zhoushan, Xiamen, Kinmen, Nan'ao, Taiwan and other places to Ganchao.

This time, Zheng Sen was summoned to discuss the matter.

When Zheng Sen arrived at the Nanjing Wharf, the head of the Lifan Courtyard was still there to greet him in person. With high-standard etiquette, he was welcomed to the newly built Yuhuatai Hotel.

Zheng Sen took a shower first, changed into regular clothes, then ate some food, and a stack of newspapers were placed on the table, praising his defeat of the West-Dutch coalition forces, and also about the restoration of Luzon.

In the afternoon, Zheng Sen was led into the palace to pay homage to Gao Huan, and Gao Huan was standing in front of a map with his hands behind his back.

"Your Majesty!" Zheng Sen came behind him to salute.

Gao Huan turned around and said in surprise: "Oh! Damu is here!"

Zheng Sen said: "I just arrived, what did your majesty think about?"

"Come on!" Gao Huan pulled Zheng Sen to the front of the map, pointed to the map and said, "Damu! You know what happened to the Dutch collusion with the Qing Dynasty!"

Zheng Sen nodded, "I have heard of it a little."

Gao Huan nodded slightly, looking worried, "Damu, you have fought with the Dutch in Nanyang. To be honest, how strong are they?"

Zheng Sen said in a deep voice: "Report to Your Majesty, the Dutch are indeed very powerful. If they were not too far from their country and the number of troops and warships was less than us, we might not have been able to defeat them!"

"Oh!" Gao Huan said in a deep voice: "I am just worried about this. The strength of the Dutch is actually not weaker than that of us. They cannot defeat us, mainly because they have too few troops. Now they have joined forces with the Qing Dynasty. If one side produces firearms and the other side produces people, they will complement each other. In this way, the Qing Dynasty may become a threat to our Central Plains again!"

Zheng Sen was slightly stunned, thinking that the Dutch helped the Qing Dynasty build guns and cannons and sell firearms, while the Qing court sent troops. When they combined, the Qing court's strength would inevitably increase greatly.

"What does Your Majesty need me to do?" Zheng Sen clasped his fists seriously.

Gao Huan patted Zheng Sen on the shoulder, "Da Mu, I didn't see you wrong."

Gao Huan paused, "I called you here, there is something to let you do. Now my energy is restrained by Li Jiyu and Zhang Xianzhong and cannot focus on the sea. Therefore, Zheng hopes that Luzon can shoulder the important task of curbing the alliance between the Netherlands and the Qing army!"

Gao Huan pointed to the map and said, "Now the British have sent troops from India and are attacking Malacca, controlled by the Dutch, to the east. I hope that the Zheng family can move south to Luzon as soon as possible, expand to Java, and attack the Dutch from east to west with the British, restrain the Dutch in the South China Sea and reduce their exchanges with the Qing Dynasty."

Zheng Sen understood Gao Huan's meaning, but the Zheng family had just recovered Luzon, and the island was in ruins and moved to the public rashly, and the people had no livelihoods. How could they live on the island?

Gao Huan knew Zheng Sen's difficulties, so he said, "I know that Luzon Island has not been developed yet, and the Zheng family rashly went to the island, and the army and their families were unable to survive and support themselves. Therefore, as long as the Zheng family moved to Luzon, I will provide you with 400,000 stones of food, so that the foreign countries will give you the most favorable national treatment to the Luzon caravan, so that the tariffs on purchasing goods from Daqian are far lower than those of Britain and Portugal."

When Zheng Sen heard this, he was immediately moved. The Zheng family started out as a maritime merchant. If they could get the most favorable state treatment, the Zheng family could rely on being a second-dea dealer to maintain the expenses of the Luzon State and even make a lot of money.

"I will follow your Majesty's arrangements!" Zheng Sen saluted.

Gao Huan nodded with satisfaction and smiled: "Okay! Tell your father more. If he really can't bear to leave the Central Plains, he can come to Nanjing to live and pass the throne of Luzon to you!"

...

While Gao Huan and Zheng Sen were discussing, Western troops gathered near the city capital.

At this time, Zhang Xianzhong stood on the platform, glanced at the elite Western army under the stage, handed a seal to Li Dingguo, and then said in a deep voice: "Dingguo! Last year, Li Jiyu was defeated in Hedong, and Tang's vitality was severely damaged. This year, Gao Huan must have taken advantage of the strength of Tang's country to attack and destroy Tang. Today, I will grant you the King of Jin, the General of the Northern Expedition, and lead a hundred thousand troops as the vanguard, and take Guanzhong in one fell swoop for me before Gao Huan."

"My son accepts the order!" Li Dingguo bowed and bowed, and took the seal with both hands.
