Song Guangkun's hydraulic power is to use water power to drive the waterwheel, so that the stone mill connected to the wooden gear is rotated, and is used to roll and polish the limestone.

The advantage of using water is that it frees up the corresponding human and animal power, and the work is much faster than that of livestock.

There are many such primitive machinery in Shandong, such as water-powered textile machines, water-powered mills, etc., but Shandong is located in the north, and in the dry period of winter, there will be a phenomenon of freezing.

If water power is to be developed on a large scale, it is necessary to dig large reservoirs to achieve the purpose of using them even in winter.

Of course, it is not necessary to excavate a reservoir for the purpose of grinding limestone and a hydraulic mill, but it is necessary to add the production of gunpowder and the use of a hydraulic boring machine to polish the barrel of the gunpowder.

Li Xingzhi clearly stated that in this era, Europe had begun to use hydraulic cannon barrel boring machines on a large scale, that is, hydraulic machinery mainly used to polish the barrel of arquebuses.

It is said that this equipment can polish the barrel of an arquebus in a day, and the craftsmen of the Ming Dynasty are still polishing the barrel by hand, and the symmetry of the inner wall depends on the feel and skill of the craftsman when drilling.

If the craftsman feels bad, it will cause the caliber and wall thickness of the barrel to be different, resulting in low shooting accuracy of the firearm, which is very easy to explode, and the efficiency of polishing is extremely low, and some even take 30 days to build a barrel, and the quality is not guaranteed.

This also has a lot to do with the income and status of the craftsmen in the Ming Dynasty, the status of the craftsmen in the Ming Dynasty is even lower than that of farmers and military households, there is no status, no income, and they can only be craftsmen forever, which makes them see no hope at all, such craftsmen, what enthusiasm can they have.

In fact, similar equipment such as hydraulic cannon barrel boring machine is recorded in Song Yingxing's "Heavenly Creation", and there are many merchants in the wealthy Jiangnan who use it to polish jade and gemstones.

It's just that the court officials are complacent, which leads to the staff bureau preferring to use craftsmen rather than use this kind of machinery, after all, the low salaries of craftsmen are nothing at all, and they can be in arrears, and to put it mildly, free labor.

If the Jingbei Army wants to develop and grow, it must increase the enthusiasm of the craftsmen and replace manpower with more efficient and sophisticated machinery, so as to create stable weapons.

There are three important issues before Li Xingzhi that urgently need to be resolved.

Article 1: Improve the treatment of artisan households, so that they can turn passive work into active work.

Article 2: Purchase hydraulic cannon barrel boring machine.

The third is to excavate large reservoirs to ensure that these hydraulic equipment can operate stably during the dry season in winter.

To this end, Li Xingzhi instructed Song Guangkun, the acting prefect of Dengzhou, to organize the people of Dengzhou to dig the reservoir, and at the same time formulate relevant regulations on rewards and punishments for craftsmen.

As for the purchase of a hydraulic cannon barrel boring machine, Li Xingzhi was ready to ask Xue Guoguan for help, because there are many Europeans in Beijing nowadays, among which the famous one is the Germanic John Tang, who not only understands the calendar but also knows how to cast artillery.

How to please, of course, it is to ask for it in Beijing, there are more than 4,000 Tartar heads and the owner of the Red Flag of the Qing Dynasty, Li Xingzhi does not think that Emperor Chongzhen will be reluctant to have a red-haired ghost.

Since the border towns are not allowed to enter Beijing without authorization, Li Xingzhi still ordered Ma Sande and Lang Shaozhen to take the Grand Canal to Beijing with this capture, after all, it is convenient and smooth to take the waterway, and they can reach Beijing in seven or eight days.

Capital.

Wuying Palace, East Warm Pavilion.

Emperor Chongzhen of the Ming Dynasty looked at the civil and military ministers kneeling on the ground with a gloomy face.

Xue Guoguan, the second assistant of the cabinet, said quietly: "Your Majesty, Liu Guangzuo, the general soldier of the Tianjin Guard, is brave and good at fighting, and in Wuqing, with only 3,000 military horses, he resisted tens of thousands of iron horsemen in the east, and beheaded 300 ranks, what is the crime?" Guan Ning's aid to suppress the general army Zu Kuan was repeatedly defeated, and he saw the eastern captives crossing the border, all of which were ineffective in the front of the superintendent. ”

"Motosuke, what do you say?"

Chongzhen's voice was hoarse, since the Dongyu broke through in August last year, except for Gaoyang, the official army has been defeated in every battle, and every battle will be defeated.

According to incomplete statistics, more than 70 county towns in Gyeonggi and Shandong have been breached by the Dongyu, killing and wounding millions of soldiers and civilians, which has made His Majesty the Emperor of the Ming Dynasty on the verge of almost madness.

"The old minister has nothing to say!"

Liu Yuliang looked depressed, the former Gaoyang was victorious, the Qing army suffered heavy losses, he thought that he would go out of Beijing to supervise the division, even if he could not defeat the Qing army, but who knew that after he left Beijing, he could not command the army of King Qin, and even Jinggi and Shandong were eroded for thousands of miles.

The teacher made a move, and the student naturally stepped forward, and the waiter Cai Yishen got up and said angrily: "Your Majesty, the minister impeached Liu Yuliang, the first assistant of the cabinet, framed loyalty, rebellion, guilt, playing with national law, disloyalty, and five major crimes, I hope Your Majesty will investigate it in detail." ”

"Yuanfu, Cai Yishen's words, what do you have to argue?"

Chongzhen opened his mouth quietly, to be honest, although Liu Yuliang is not capable, he can reconcile in the middle, and he also knows that Liu Yuliang cannot be blamed for the defeat in the front.

Liu Yuliang glanced at Chongzhen gratefully, and just as he was about to speak, Chen Xinjia, the left attendant of the clinker military department, stood up again.

"Your Majesty, the minister just received the Wuqing battle report today, and Liu Guangzuo, the chief soldier of Tianjin, defeated the Dongyu, beheaded two hundred and twenty-seven levels, and saved nearly 10,000 people."

"Alas...... Your Majesty's old ministers invite themselves! ”

Liu Yuliang sighed, turned his head and glanced at Chen Xinjia, he knew that this was instructed by Yang Sichang, and when Xue Guoguan impeached Liu Guangzuo, Wang Pu, Zu Kuan and others did not obey the order, he took out this good news, this is to kill himself.

Fan Fucui, a scholar, said angrily: "Can you disobey orders if you have military merits?" After the first time out of Beijing, Lu Xiangsheng was defeated in Julu, Chen Hongxu of Jinzhou actually refused to open the door to accept the army of King Qin, Liu Guangzuo, the general soldier of Tianjin, and Wang Pu, the general soldier of Datong, disobeyed the orders of the superintendent Yang Fengyin, Hu Dawei and Yang Guozhu retreated into Shanxi, Guanning army, hehe Guanning army superintendent of the division? ”

Fan Fucui's voice was loud, pointing directly at Yang Sichang and Chen Xinjia manipulating authority, making Liu Yuliang, the supervisor, nominal and insubstantial, and Lu Xiangsheng's defeat was also the main reason why Hu Dawei and Yang Guozhu avoided the war and protected themselves.

"Scholar Fan, this statement is very absurd, since the first person is holding the Heavenly Constitution, then it is natural to give clear orders and reward and punish them strictly, so that the generals can use their lives sincerely, on the contrary, the generals do not obey the orders, and the first person is not to blame?"

Although Xue Guoguan and Yang Sichang are vying for power and profit, since they have a common enemy, they naturally want to exonerate Yang Sichang, but he didn't want to put Liu Yuliang to death, the meaning of his words is very clear, Your Majesty, you see, Liu Yuliang is a scumbag, it is better for the old man to be the first minister.

"Hehe, you and other private ministers collude to frame Zhongliang, fight for power and profit, and the major affairs of the court will be destroyed in your hands."

Fan Fucui sneered again and again, he really couldn't answer Xue Guoguan's words, after all, this guy captured Abatai alive without a single soldier, so he had to attack Xue Guoguan and Yang Sichang for colluding.

"Alright, stop arguing! The state affairs have been so corrupted that you don't think about how to repay the effect, and all day long thinking about it is to eliminate dissent, and you can defend yourself against today's impeachment. ”

Chongzhen's voice was hoarse, the main force of the Eastern Captives was still on the front line of the Great Wall, and the ministers of the DPRK and China did not want to fight thieves for the country, but they attacked each other here, I really don't know what to say, at this moment he actually had the intention of protecting Liu Yuliang.
