During this time, Cao Yue was very busy, but he also lived a very fulfilling life.

Everything in Nanjing basically developed as he thought, including the progress of recruiting and training troops, as well as the trends in Nanjing's officialdom.

Jinyiwei is really a big killer, his brother Cao Chao and a few buddies are there, mastering the main power of Jinyiwei, after those officials with bad deeds in Nanjing officialdom are mastered, no one dares to fight with him. Although Cao Yue knew that it was a bit immoral to coerce people like this, he was not ashamed to use such means to deal with people who were more immoral than him.

In addition, the training of the special guard battalion and the privacy of the officials are also one of their important subjects, and these elusive people almost make the officials in Nanjing panic, and they can't figure out why they do a lot of private things that Cao Yue knows. They were full of fear and anger at Cao Yue, but there was nothing they could do. Seeing that the officials in Nanjing were very jealous of themselves, and they looked like they dared to be angry but did not dare to speak, Cao Yue felt a sense of accomplishment. Thinking about his lofty goals, he also lost his psychological burden.

There is a saying, those who achieve great things, why bother to be small?

He is not afraid of the retaliation and impeachment of the officials, and he has mastered the army, so who else should he be afraid of?

What's more, he still has Emperor Chongzhen's Shangfang sword in his hand, which can be cut first and then played, which is also a big killer, and no official is not afraid.

More than 75,000 non-commissioned officers from 15 battalions have been incorporated into the Nanjing Town Army, and they are being trained in an orderly manner, and the follow-up conscription work is continuing.

Tens of thousands of soldiers from Jiangsu and Zhejiang have also been recruited and are on their way to Nanjing. According to Cao Yue's statistics, Emperor Chongzhen gave 100,000 people, but now he plans to recruit more people, he can send one or two battalions to reinforce when the war in Shaanxi and Henan is in full swing, and then he can take the opportunity to ask the imperial court for more troops, I believe that Emperor Chongzhen will not refuse.

There was a serious shortage of generals under his command, and Cao Yue also tried to dig up from other armies.

Yan Yingyuan, Zhang Huangyan, Huang Daozhou, Qian Sule, Wang Yi and other talented people who Cao Yue knew or didn't know about their reputations were all dug into the Nanjing town army. Yan Yingyuan is still a small official, but Cao Yue, who knows his historical name, specially sent someone to poach him from Jiangyin, where he worked. Zhang Huangyan is Zhang Cangshui, and Cao Yue also knows his name, so he specially sent someone to invite him to serve in the Nanjing Army. And Huang Daozhou, Qian Sule, and Wang Yiju were the people recommended by Zhang Cangshui, and after knowing the talents of these people, Cao Yue gave them important positions in the army.

Preparations for the construction of the Nanjing Firearms Factory are also progressing smoothly, and the site of this new arsenal was chosen in the area of Shogunate Mountain, close to the Yanziji Camp. The original weapons workshops in Nanking were also retained and continued to produce gunpowder and other firearms. The newly built arsenal will use the newly acquired machines to mass-produce muskets, grenades, and artillery, and will begin to produce flintlock muskets using Western craftsmen.

Wang Yuyou, Song Yingxing, Wang Zheng, Sun Yunqiu, Fang Yizhi, Gu Yanwu and other Cao Yue knew his fame or learned from other channels that he was a scientific and technological talent, and he also found a way to dig it up.

Song Yingxing, the author of "Heavenly Creations", is definitely a super awesome man in this era, but his talents have not been valued in the Ming Dynasty, which does not attach importance to science and technology. In the fifteenth year of Chongzhen, Song Yingxing angrily resigned and returned to China for some well-known reasons, and Cao Yue sent someone to invite him to Nanjing and entrusted him with the important post of being in charge of the newly built Nanjing Arsenal. Song Yingxing, who had long admired Cao Yue's reputation and wanted to make a difference, agreed to Cao Yue's invitation to preside over the affairs of the arsenal for Cao Yue.

Wang Zheng was another very famous scientist in the late Ming Dynasty, he loved ancient artifacts and machinery in his early years, and before he came out, he developed hydro, wind and load-bearing machinery, and wrote "The Illustration of the New Instruments". Later, together with the Swiss missionary Deng Yuhan, he compiled the "Diagram of Strange Instruments in the Far West", which mainly described the knowledge of statics in ancient and Renaissance times in the West, including geocentrism, the center of gravity and its solution, the volume of water, the volume of floating bodies, the specific gravity, simple machinery and their combined use. The Illustration of Strange Instruments of the Far West is the first compilation of Western mechanics in China.

Cao Yue had seen Wang Zheng's information in the history books, so after digging him up to Nanjing, he also asked him to be in charge of the arsenal, and together with Song Yingxing, he presided over the development of new equipment and firearms.

Sun Yunqiu was a famous optical master in the Ming Dynasty, Fang Yizhi was also a famous physicist, and Cao Yue admired their reputation in history and dug them up through a lot of efforts.

These men, along with some Western craftsmen hired by Cao Yue, formed the technical team of the newly formed Nanjing Arsenal.

Cao Yue hopes that through his strong support and the intelligence of these people, he can design and manufacture more weapons and other instruments full of advanced technology, and elevate Daming's science and technology to a new level.

These people can be said to have great admiration for Cao Yue's military exploits, and Cao Yue sent people to ask them to promise them a lot of favorable conditions, and when they arrived in Nanjing, they could make the best use of their talents and develop what they had learned, and the status that Cao Yue gave them was not much higher than what they had before, which made them very satisfied. From Western craftsmen, they can also come into contact with more advanced knowledge and technology.

It can be said that these people that Cao Yue spent a lot of energy and financial resources to dig up, and after arriving in Nanjing, they all felt like a fish in water.

No one dares to be lazy, and no one will be lazy, they are all committed to their work with a hundred times the enthusiasm, and want to develop more and more advanced things through their own efforts, giving Cao Yue more surprises. In particular, Song Yingxing, who was appointed by Cao Yue as the director of the Nanjing Arsenal, was invited by Cao Yue to take up an important post after resigning and returning to China, and he was deeply moved by the kindness of his acquaintance, and he devoted almost all his energy to the suggestions of the Nanjing Arsenal and the subsequent development of various instruments and weapons, and really reached the point of forgetting to sleep and eat.

Although it is said that the situation in the Ming Dynasty is strong now, from the efforts of these people and the rapid growth of the Nanjing Zhen Army, Cao Yue still sees hope. He believed that as long as he was given four or five years, he would be able to build the Nanjing Zhen Army into an invincible army in the world, and no enemy would be an elite division of the opponent. It's just that Cao Yue knew that the development of the situation could not give him four to five years of development opportunities, and Emperor Chongzhen would not let him stay in Nanjing for so many years and lead so many troops. He must seize the opportunity and strive to build the Nanjing Town Army into an elite army in the shortest possible time, develop and build the Nanjing Arsenal well, and design and produce more and better firearms.

For this reason, Cao Yue also devoted all his energy to training troops and supervising the construction of arsenals, and he often did not have time to return home.
