The reason why Guo Zhiyuan was able to achieve the brilliant results that Qi Jiguang had not been able to achieve this time was not that he was better than Qi Jiguang, but because the Japanese invaders underestimated the enemy, they felt that Guo Zhiyuan had fewer troops at hand than themselves, and they could directly crush them, so they would go out and give Guo Zhiyuan the opportunity to make dumplings, otherwise as long as the Japanese invaders used guerrilla tactics when fighting with the Daming Water Division, Guo Zhiyuan would have a headache.

Although the battle with the Japanese pirate coalition was won, it was actually very hard, and almost every soldier of the New Army was wounded, which also exposed the shortcomings of the insufficient forces of Dongfan, if the Japanese were not fooled and did not enter the ambush encirclement set up by Guo Zhiyuan in Jilong Bay, but divided the troops to fight Beigang and the big soldiers, then Guo Zhiyuan was really blind.

So this time, Guo Zhiyuan is preparing to expand the army and expand the new army to 30,000, so that he can put 10,000 new troops in Beigang, Keelung, and Dayuan, plus Liu Ruosi's garrison and Shen Yourong's sailors, which are enough to protect the safety of Dongfan.

The source of the expansion of the army is also easy to solve, now the new immigrants in Dongfan have approached 200,000, and the sense of identity with Dongfan is very high, as long as Guo Zhiyuan posts a recruitment announcement, there must be a large number of applicants, most of these new immigrants are young and strong, and the nutrition has also kept up after arriving in Dongfan, plus Guo Zhi** when the new immigrants are used for work and labor are militarized, the quality of the soldiers is not bad, as long as a little training, let the veterans of a hundred battles in the new army bring the old with the new, and soon be able to form combat effectiveness.

In addition, for the two "wonder soldiers" who have made great contributions at the critical moment of this war, the Atayal warrior army led by Abu and the Black Rakshasa army led by Dax Guo Zhiyuan are also ready to further expand, and now Abu and Guo Zhiyuan have abandoned their previous suspicions, and fighting can make the clansmen live a happy life without worrying about food and clothing, where to find such a good thing, so Abu was very concerned when he heard that Guo Zhiyuan was going to expand the army, and went into the mountains early in the morning to find Atayal people from other clans and recruited troops for Guo Zhiyuan.

The Black Rakshasa Army Guo Zhiyuan is ready to expand to 500 people, Dax has already followed the sea trade fleet to the sea, to find his old department in Luzon, Guo Zhiyuan gave him enough silver, even if he can't find the old department in the past, there are many blacks who work as coolies in the Luzon docks, and it is easy to make up 500 Black Rakshasa Army.

However, there is a problem here, this time Emperor Wanli rejected Guo Zhiyuan's request to expand the number of troops, indicating that Emperor Wanli has become wary of Guo Zhiyuan, if Guo Zhiyuan expands the army with great fanfare, it will be equivalent to a direct rebellion, for the time being, Guo Zhiyuan does not want to tear his face with the imperial court, so Guo Zhiyuan can only use a roundabout strategy, he let half of the existing soldiers of the New Army "retire" due to injury, and then recruit new recruits to fill up, and then let the other half of the New Army "retire" after the recruits form combat effectiveness, and then recruit new recruits to fill in, But in fact, those "retired" veterans are retired without stopping, and can be called up at any time, which is equivalent to doubling the strength of the new army.

The most headache for Guo Zhiyuan is weapons and equipment, the weapons and equipment needed by the 30,000 army is not a small amount, and now the imperial court has become wary of Dongfan, and the inventory of merchant ships coming and going to Dongfan is very strict, and military materials are strictly controlled, so it is difficult to buy military standard weapons and equipment from the inland, but fortunately, there are a lot of weapons and equipment captured by the pirates this time, although the damage is serious, but the craftsmen of the workshop can barely be used to repair it.

However, this is not a long-term solution after all, Dongfan must have its own weapons and equipment research and development and production capacity, so as not to be stuck by the imperial court, so this is the second major thing that Guo Zhiyuan is going to do, to set up a military factory in Dongfan!

In fact, as early as Gutian, Guo Zhiyuan secretly built a weapons workshop, which is equivalent to having the prototype of a military factory, and after arriving in Dongfan, he specially allocated funds to Zhao Shizhen to let him build a secret military research institute in Yangmingshan.

But research and development is one thing, to mass production and assembly of troops is another, this era can not have modern industrial assembly line operation machinery and equipment, production efficiency is frighteningly low, such as flintlock pistol, Zhao Shizhen has long invented it, but only one barrel requires a skilled craftsman to do a month to complete, the weapon workshop is in full swing, and a month can produce at most a dozen flintlock pistols. Therefore, although Guo Zhiyuan had long planned to set up a military factory, he has never been able to realize it.

However, this problem has now been solved, not long ago, Zhao Shizhen has taken his R&D team to invent a hydraulic machine tool! In fact, Guo Zhiyuan has long said to Zhao Shizhen about the principle of hydraulic machine tools, but because of the high precision requirements of machine tools, he has not been able to make qualified finished products.

This time, the hydraulic machine tool was successfully invented, but it was a person who was almost forgotten by Guo Zhiyuan who made a great contribution, and this person is Wang Zheng! Wang Zheng was originally a member of the imperial court sent to Dongfan to mix sand, and later this group of officials mixed with sand was driven away by Guo Zhiyuan's envoy, only Wang Zheng stayed, Wang Zheng and Xu Guangqi together in the original historical time and space and called "the king of the south and the north", for Western machinery is quite researched, especially good at mathematics, so Guo Zhiyuan is also very polite to him, and he is trying to win over.

But Wang Zheng has always been unpretentious to Guo Zhiyuan, and over time, Guo Zhiyuan has also become a little disheartened, and there are too many people and facts that Dongfan wants him to worry about, so he gradually forgot that there is such a great god by his side. Wang Zheng stayed in Dongfan for so long, felt the new atmosphere here and the twilight of the imperial court is completely different, and his mood slowly changed, although he is not very cold to Guo Zhiyuan, but he is also obsessed with academics Zhao Shizhen is very chatty, Zhao Shizhen also has no sense of confidentiality, when the research and development of hydraulic machine tools encounter problems, he likes to pull Wang Zheng to discuss together, Wang Zheng is especially good at mathematics, just learn from Zhao Shizhen's strengths, the two scientific maniacs have been tinkering for months, I really invented a hydraulic machine tool!

With hydraulic machine tools, Guo Zhiyuan's idea of building a military factory for large-scale production of weapons and equipment can be realized, in the past, it was only possible to make a flintlock barrel by a person by hand for a month, but now a flintlock barrel can be bored in half a day by a hydraulic machine tool, even if you count the manual grinding process in the later stage, it takes less than three days to produce a flintlock barrel, which is equivalent to increasing the production efficiency by ten times!

And with hydraulic machine tools, many new inventions of the Military Industry Research Institute can also be mass-produced, such as a plate armor newly invented by Zhao Shizhen. The armor rate of the Ming Dynasty army is actually not high, the average soldier can only wear cloth armor or leather armor, only senior generals can wear iron armor, which is also an important reason for the Ming Dynasty army's combat effectiveness is not strong, in the face of the Manchu army that is good at cavalry and shooting, the protection of cloth armor or leather armor is equal to zero, and it has completely become a straw harvested by the Manchu army!
