As Yu Guozhen expected, Cao Huachun asked for Emperor Chongzhen.

At this time, Emperor Chongzhen was already unprecedentedly disappointed in the princes above the court, and he was ready to let Wen Tiren regain his appearance after this incident. But the premise is that he can deal with this trouble, and he can't let Wen Tiren go out to supervise the division as a general, and there is no one available in his hands, so after thinking about it, he thought of Yu Guozhen.

Perhaps, Yu Guozhen, who caught Gao Yingxiang for him, can still bring him some kind of surprise?

Yu Guozhen closed his eyes slightly.

If it weren't for the current situation, he really didn't want to come out and lead the limelight at this time. His original plan was to let Chongzhen and Donglin toss the Ming Dynasty together, farm in the south, immigrate to Southeast Asia and Oceania, control the Strait of Malacca, subdue the Japanese and North Korea, and then take advantage of the time when the Liukou wiped out the Ming Dynasty and the "purple fart from the east" of the Eastern Captives, waved his army to the north, and appeared in the Central Plains with the majestic posture of a liberator.

Doing so is not inferior to Zhu Chongba's expulsion of the Mongol Tartars to restore China, and Yu Guozhen can also rely on the solid foundation he has laid overseas and his supreme personal authority to push China to start a new round of expansion: not simply territorial expansion, but the expansion of science and technology, the expansion of transportation, the expansion of population, and the expansion of production.

However, in order to do so, he must first be hard-hearted and let the rogues plague the Central Plains and Nanzhili, so as to obtain the population he needed to lay the foundation overseas, weaken the strength of the Ming Dynasty, and at the same time avoid fighting with the Tartars in advance as much as possible, so as not to expose his strength too early, and at the same time avoid weakening the Eastern Prisoners too much.

But it's just that although he knows the general trend of the end of the Ming Dynasty, he doesn't know its details, so he is repeatedly involved in conflicts.

This was the case with the Liukou battles last year and the beginning of this year, as well as the invasion of the Eastern Captives in Jingshi now.

He still has a chance to avoid it now, but, in the face of those brutal invaders, dodge ...... Is it really the best choice?

In Nanzhili, he fought with Liukou twice, and he gained a large number of people, adding up to 120,000 before and after, and won the favor of some talented people, not to mention Fang Yizhi, like Xu Xiake, Song Yingxing, Wan Shihua and even Zhang Chi. There are also those who were originally unknown in history, who came to Xiang'an one after another, and in only two or three months, nearly 1,000 people took refuge in Xiang'an.

People's hearts are righteousness, luck, and destiny.

Even if the battle in Jingshi could not bring him many benefits like in Nanzhili, he had to do it, just to ......

He thought of Fang Ziyi's silent prayer that day.

"Cao Gong, this invasion of the Eastern Prisoners, although there are minor troubles, but it will definitely not be able to break through the Beijing Division, as long as the Beijing Division strictly guards the city and works carefully, the Eastern Prisoners will never take advantage of it." He thought for a moment, then said.

Cao Huachun was slightly relieved, Yu Guozhen knew the soldiers, at least he knew the battlefield situation better than him, since Yu Guozhen said that the Dongyu could not enter the city, there was no big problem.

"If I am a captive chieftain, this expedition should have the purpose of destroying the towns and villages near the Jingshi, plundering the population, and destroying farmland. Now my Ming national strength is still far superior to that of Dongyu, Dongyu's move is like a knife in my Ming chest, although it can't kill me with one blow, but it can make me continue to bleed and weaken our national strength. The Eastern Captives have always entered the prison and entered the Kou, and their purpose is the same. ”

Cao Huachun thought about it, it was true, before the capture of the East into the Kou, it was nothing more than a plunder and left.

"Donglu is not good at attacking cities, and my Daming firearms have the advantage, but after Kong Cheng and others went to vote, he also brought Denglai's skilled craftsmen and cannons into Donglu, so that now Donglu also has cannon firearms, at least in terms of equipment, it is already equivalent to my Daming." Yu Guozhen said again.

Cao Huachun didn't like to hear these words, and he couldn't understand them, he was a little impatient: "Jimin, what do you want to say?" ”

"It is to explain to Cao Gong the advantages and disadvantages of the enemy and me." Yu Guozhen said with a smile: "Cao Gong is the companion of the Son of Heaven, if the Son of Heaven asks about this, Cao Gong also has something to talk about." ”

When Cao Huachun heard this, he smiled and motioned for Yu Guozhen to continue. Yu Guozhen raised a finger: "But Kong Youde Geng Zhongming is still happy that the three thieves have been in the Houjin for only four years, although the Houjin has artillery, the use of the performance is not yet proficient, so the Dongyu has not yet been equipped with firearms on a large scale, I am in Qin'zhou, trade with the Fanren, and the Fanren firearms are sharp, so I have to buy them." If the Ming Dynasty wants to conquer the East, it must rely on firearms, and the firearms of the Fanren are better than me, so why not buy them for the use of our army? ”

"That's far water, you can't quench your thirst!" Cao Huachun said impatiently, but when he saw Yu Guozhen's smiling appearance, he immediately understood: "Okay, you little monkey, you actually calculated that our family is here...... We don't dare to say anything else, the master who buys 10,000 firecrackers for the imperial court a year can always do it! ”

He is worthy of being a eunuch waiting for people, and he is the best at figuring out people's hearts, and when he saw Yu Guozhen's appearance, he immediately understood that Yu Guozhen was actually selling him the firearms of the fans. This kind of sales, the imperial court is impossible to directly trade with Fanren, so the middleman is Yu Guozhen, he is in the middle of the sale, and the profit should be not small.

But there are also things he can't think of, as soon as he opens his mouth, it is 10,000 firearms, and in his mind, even if someone comes to make it, it should be extremely time-consuming. You must know that it is extremely difficult to make a bird gun at this time, and the difficulty is on the barrel, according to Qi Jiguang's statement in the "New Book of Ji Xiao", the barrel must be drilled by a steel drill, and the time of a day, the power of one person, can only drill into an inch, "to the end, the drill in January is the top", that is to say, a craftsman can drill a qualified barrel in a month is very good!

He didn't know that in Xinxiang, hydraulic machinery was used to drill the barrel, and the high-hardness knife steel made from a crucible was used as the drill bit, and the oil pump was used to apply pressure and circularly spray cooling oil to cool the drill bit and flush the barrel. With this method, it takes less than two hours to drill a barrel!

As for parts such as bolts, it is even more convenient to use the stamping method to cast. After all the parts are made, they enter the assembly line of the ironwork workshop ordnance workshop, where they are completed by craftsmen in a streamlined manner. The whole process is completely industrialized, not only its output is hundreds of times better than the manual process of Chuantong, but also because it is completed by machinery, which reduces the error of human judgment, and makes the accuracy of the parts far better than that of manual work. This ensures the quality of the finished product, prolongs the service life, and reduces the possibility of exploding.

Yu Guozhen estimated that the cost of each Huwei B type was about one tael, while the cost of the shoddy firecracker with only more than 30 rounds of ammunition was 223 yuan, and the cost of the "qualified" firearm that could send 100 bullets needed to be 328 silver and silver!

He only sold these firearms to the Ming court at a price of three taels, and he could get a profit of two taels, and with the expansion of the scale of production and the further improvement of the process, his cost could be lower.

He is not afraid that these firecrackers that flow into the hands of the Ming court will be used against him, firstly, this must be the external sale type of Huweiyi, and the range and accuracy will be affected, and its power will only be slightly greater than the similar firecrackers used by the Ming court now, and secondly, it will ...... By the time someone used such weapons against him, he already had the weapons to shoot longer, shoot more accurately, and defend more strongly.

"Cao Gong, this time the eastern captives are invaded, if the generals use their lives, the general soldier of Datong, Wang Pu Neng, can choke the Xuanfu, and the general soldier of Shanyong, Zu Dashou, can guard the Jiumen Shuikou, and the local guards defend themselves according to the city, so that the captives have nowhere to plunder, and then mobilize the troops of the Quartet Qinwang, and the decisive battle with the Dongyu under the Jingshi City, it is to exchange two for one, and it can also make the Dongyu Jinghua and be buried here. Since then, Liaodong has no worries! ”

What Yu Guozhen said was to close the door and beat the dog. The Donglu army entered the customs, either to Xuanda, or to the Shanhaiguan, to block these two openings, and then the Donglu wanted to get out of the customs, that is, to detour through the desert, not to mention the difficulty, but along the way the Ming army harassment was enough to let the Dongyu 100,000 horses and armor not remain. This can also be said to be a good opportunity for the Ming Dynasty to carry out a strategic decisive battle with the Eastern Prisoners, although the price paid may be that the left of the Beijing division will be broken, but anyway, if there is no decisive battle, the left of the Beijing division will also be ravaged by the East and defeated.

But Yu Guozhen knew that it was impossible for Chongzhen and Cao Huachun to adopt this strategy!

After years of fighting with the Dongju, Chongzhen, Cao Huachun and others have instinctively feared the Donglu, and they will never dare to look at the Donglu under the Jingshi City, and they must try to drive them away. In addition, Chongzhen also lost confidence in his Wenchen generals, and did not believe that those generals could hold the pass city and wait for the arrival of King Qin's reinforcements.

Sure enough, Cao Huachun just thought about it for a moment, and then shook his head: "No, no, Jingshi is the henchman of the country, how can he let thieves run rampant?" Moreover...... If the thief does not wait for the king to arrive, he will attack the city with all his might, so what can he do? ”

Yu Guozhen smiled: "That being the case, I still have a second strategy. The imperial court appointed Yisu as the governor to govern all countries other than the capital division, awarded Shang Fang the sword, and allowed him to kill those below the general army who did not obey the order. The military order was unified, and the battle with the captives was fought in Gyeonggi. Now there are only 100,000 captives, and our soldiers also have this number, there is no need to defeat the captives, just frustrate their spirit, and the captives will not be at ease, but want to flee. After that, he attacked and harassed along the way, forcing him not to retreat calmly with the property of the people he plundered, although he could not win a big victory, but he could also make the captive army return empty-handed. ”

Cao Huachun's eyes lit up when he heard this strategy, this was in line with their intentions, anyway, those who fought did not need to use the Beijing camp, but only used the troops under the general army of the towns near Gyeonggi. However, after thinking for a moment, Cao Huachun said: "The Son of Heaven intends to make important ministers in the court as supervisors, such as Zhang Fengyi, the secretary of the military department, and lead the army. ”

"No, no, this matter cannot be led by Wenchen." Yu Guozhen shook his head again and again: "Especially Zhang Fengyi, it is even more impossible." It's a rogue, and he can't deal with it, let alone the Dongyu? ”

His evaluation of Zhang Fengyi, the secretary of the military department, was quite low, Cao Huachun smiled, but did not say anything more.

The Son of Heaven has his own conclusion in his heart about this matter, but it is not for him and Yu Guozhen to decide.

"Is there any other plan?" Cao Huachun asked again.

"The rest of the strategy...... If the imperial court doesn't want to lose face too much, it can send a general out of the city, allocate more war horses and ordnance, and let the Jinyi guard help, pass on the news, and kill the scattered and plundered Eastern captives, and leave with one blow, and never love war. Yu Guozhen said to Cao Huachun: "There is such a ranger here, or it can do miraculous feats." ”

When he said this, he looked at Cao Huachun with a smile, Cao Huachun got up and said, "You have no one to bear this matter unless you are a citizen...... Whatever you want, just tell me! ”
