Gao Junshan asked Erbao again, Erbao is studying military command, and he will lead troops to fight in the future, studying at Chongwen Military Academy, and is currently learning to arrange troops, Gao Junshan listened to Erbao's report for a while, and then instructed Erbao to learn from the professor seriously, to integrate theory with practice, and not to learn Zhao Kuo only on paper. ”

Then the Three Treasures and the Four Treasures also reported to Gao Junshan about their learning, the Five Treasures and the Six Treasures were still young, and Gao Junshan did not ask for more, but just listened to the poems read by the two of them.

The next day, Li Guo was in a hurry to return to Xi'an, Gao Junshan gave him a generous gift, and also sent someone to send him out of Xiangyang.

Gao Junshan was also busy in Xiangyang, because he knew that there would be big changes in the Ming court in less than half a year, and he had to seize the day and prepare for a big battle with the Qing army. He had already received a report from Liu Lishun that Huang Taiji had died a year earlier, and he had not named an heir before his death. Huang Taiji's ninth son, Fu Lin, due to his half-brother Hauge and his uncle Dolgon competing for the throne, under the balance of interests of many parties, finally Dolgon helped this ninth son Fu Lin to succeed to the throne. Fu Lin was only six years old when he succeeded to the throne, and was assisted by Dolgon and Zilharang, and the Qing court was already under Dolgon's control.

In other words, the Tartars that Gao Junshan has to deal with now are the Qing army in power in Dorgon.

The Qing army had the advantage of cavalry in field warfare, and if they wanted to defeat them, they must use hot weapons, and it was imperative to produce hot weapons in large quantities.

Early the next morning, Gao Junshan walked out of the dormitory and shouted: "Sun Kewang prepares the car!" ”

Han Yuyan heard Gao Junshan's voice, chased him out from behind and asked, "Master, why don't you eat some breakfast?" ”

Gao Junshan said: "I'm not hungry now, I have urgent things to do." ”

Han Yuyan complained: "It's always in a hurry and can't go home!" ”

……

Gao Junshan's carriage stopped at the gate of the ironworks on the bank of the Han River, and Sun Yuanhua, who got the news, was already waiting at the door, and as soon as they met, Gao Junshan said eagerly: "Huo Lao, quickly report to me on the production of the Mini gun!" ”

Sun Yuanhua saluted Gao Junshan before saying: "The production situation is good, and the workers are stepping up production. ”

Gao Junshan couldn't wait to ask: "What is the daily output?" ”

Sun Yuanhua replied excitedly: "Thirty sticks per day." ”

"Thirty sticks per day? No, no, no! There is dissatisfaction on the high mountain face, "Too little." Time is not waiting for me! To increase the number of manpower, at least 50 sticks per day. ”

Sun Yuanhua originally thought that Gao Junshan would praise him, but he didn't expect that he was still less than enough to produce thirty mini guns a day, Sun Yuanhua's face was a little unbearable, and he didn't squeak with a blue face.

Seeing that he didn't react, Gao Junshan didn't care about what his old man thought, waved his hand and ordered: "Take me to see the production of the barrel!" ”

There were also two Chongwen disciples beside Sun Yuanhua, one of them led the way and the other helped Sun Yuanhua to walk towards the ironworks, because the water-operated boring machine for making gun barrels was placed in the ironworks.

Gao Junshan saw that Sun Yuanhua had to be supported when he walked, so he thought that Sun Yuanhua was not young, and he still insisted on being on the front line of production, and thought of what he said just now because he was anxious, so he hurriedly apologized to Sun Yuanhua and expressed his condolences.

Sun Yuanhua's face improved at this time, and he asked in a deep voice, "Is it going to be a big battle?" ”

Gao Junshan said firmly: "Yes. In half a year we will be engaged in war with the Tartars, who are good at riding and shooting, and we can only use this firearm to strike them with great force. ”

Sun Yuanhua said: "In order to fight the Tartars, the old man gave up his life to increase the output, but the old man has a request, and I hope that the king of Qin can agree." ”

Gao Junshan said: "If Huo Lao has any requests, I will definitely do it if I say it." ”

Sun Yuanhua gritted his teeth and said: "When you meet traitors and rebels like Kong Youde and Geng Zhongming, don't be polite to me, and clean them up ruthlessly." Because these scum took a unit that I spent a lot of money to build with Western firearms as the main combat weapon, and was taken out by these traitors and rebels to cast Tartar. ”

Gao Junshan comforted: "Huo Lao rest assured, not only traitors such as Kong Youde and Geng Zhongming, but also traitors such as Hong Chengchou, Li Yongfang, Sun Degong, and Fan Wencheng who helped the Tartars to help the abuse, I will execute them one by one!" ”

"Well, with your words, it's worth it for me to die in the craftsman's workshop."

Gao Junshan hurriedly said: "I am very touched by Huo Lao's determination, but I don't need you to fight so hard, I will send you more people, you just give me a good quality." ”

Sun Yuanhua was happy, and he smiled: "It's still King Qin who cares about the old decay!" ”

"You're our baby!" Gao Junshan said half-jokingly and stepped forward, "Take me to see how you make the barrel of a gun." ”

They went up to the second floor, which was fifty paces square, and under the wall against the river there was a hydraulic boring machine, and three masters were working. Gao Junshan once came here once, and the purpose of his return was to see if this hydraulic boring machine had improved.

This boring machine is about 20 zhang long and 5 zhang wide, and there is a large wooden wheel rotating at one end, driving the machine to run.

Gao Junshan asked Sun Yuanhua: "How many hydraulic boring machines have been built?" ”

"Return to King Qin, Liutai."

Gao Junshan pointed to the big wooden wheel and asked, "Do you still use this wooden wheel as a transmission?" ”

Sun Yuanhua said: "There is no problem with this!" It's always working fine, but it's just going to be replaced every three months. ”

"Why don't you go up on a different iron wheel?" Gao Junshan asked dissatisfiedly.

Sun Yuanhua wrote a big question mark on his face: "Is this okay?" ”

Does this still need to be asked, the factories of later generations are all iron lumps, how can there be wood to make transmission wheels? Of course, Sun Yuanhua can't be blamed for this, after all, he has not seen the machines of later generations, Gao Junshan is still sensible, and he answered Sun Yuanhua's question with certainty: "Of course." You don't have to change the iron wheel every three months, you just need to add some oil often. ”

Sun Yuanhua nodded as if he had been empowered: "Oh, the iron wheel is harder than the wooden wheel, why didn't I think of it before?" ”

Gao Junshan pointed to the transmission wood gear under the wooden wheel: "The gear below is also replaced with iron." ”

"Are there any technical issues with these?" Gao Junshan didn't hear Sun Yuanhua's reply, and asked again.

"Nope. But I'm thinking, iron is not hard. Sun Yuanhua replied.

Gao Junshan asked, "Do you think of other aspects of design?" ”

"Yes, I'm thinking about how to increase the range of artillery."

Gao Junshan saluted Sun Yuanhua and said, "Huo Lao is always thinking about problems, which is admirable!" ”

Sun Yuanhua said modestly: "People are old and useless, you see, I can't imagine that this wooden wheel can be replaced with an iron wheel." ”

Gao Junshan took Sun Yuanhua's hand and said kindly: "It's not me asking you for time now!" It's the current situation, if we can't form a Mini gun battalion to deal with the Tartars, once we fight the Tartars, we will have to pay a great price with our lives. ”

"The old minister understands!"

Gao Junshan confessed so sincerely, can Sun Yuanhua not be moved?
