Beijing.

"It's finally here!"

Dorgon said through gritted teeth.

The man who made him unforgettable finally came......

Well, that's not an exaggeration!

How many times he woke up in his sleep, reliving the damage he had done to his body and mind, how many times he saw or heard the name and the hatred was irrepressible, as evidenced by the wooden statue in the secret room of his dormitory, which was almost indistinguishable from human form!

It's been seven years!

It's the eighth year to be exact.

After all, the battle of Shanhaiguan was in the spring, which was the spring of the seventeenth year of Chongzhen, after which Chongzhen died in the eighteenth year, and then the Longxing year was called five years, which was February of the first year of Kunxing.

It's actually been almost seven years.

As a man who lost an organ, he suffered in humiliation for seven years, not only to endure the contempt implied in the eyes of others, but also to endure the inevitable sequelae. Although he is the regent and is in fact the lord of the Qing Dynasty when Fulin always stays in Shenyang, who knows how painful he is when no one is around? Was it just two little things he had lost? What he has lost is dignity, a symbol of a man, and his future, and he doesn't even have an heir!

Although this problem is not serious!

After all, he had a son of Duoduo!

He still has ......

But can that be the same?

And the culprit of all this tragedy for him is a man, that man, that demonic man......

"Recall King Yu, this king will fight to the death with this thief!"

Dolgon subconsciously pinched the orchid's fingers and shouted.

"Regent no!"

……

Hong Chengchou and Ning Wan stopped him at the same time.

"Regent, then Yang Qing can't beat Dagukou in the short term, even if he has beaten Dagukou, Junliangcheng, and Tianjin City, neither of which is easy for him to pass, it can be said that he can't threaten Yanjing in two or three months. But two or three months was enough for Li Zicheng's army to come to the Huai River, and Yang Qing's move was just a bluff to force King Yu to return to the division, and now it was the time for the three parties to wrestle. After the loss of Jinan, it was inevitable that the Ming army on the southern front would attack Dongchang, but at the same time, the army of King Yu was also attacking Zhengzhou, and Li Zicheng's army had already arrived in Yingzhou to begin to attack the city, and whoever broke through first was the final victor. The Ming army broke Dongchang first, we lost, we broke Zhengzhou Yang Qing first, and Li Zicheng broke Yingzhou first, and Yang Qing also belonged to Yang Qing, this kind of wrestling is to fight endurance.

Yang Qing's move is to mess with our position.

King Yu not only could not move, but also had to increase reinforcements for him, as long as he captured Zhengzhou, it would be a great thing.

Yang Qing can only be defended.

In order to increase the defenders of Tianjin and Junliangcheng, he ordered the Beitang Water Division to attack and disturb, sent cavalry to patrol the north bank of the Haihe River, and once the Ming army broke through the Dagu Pass, it would use cavalry to attack on the north bank. Seeing that spring had begun, the south bank of the Haihe River had become a swamp, and the Ming army could not march to Tianjin by land, so they could only take the Haihe River waterway, but their cruisers had a deep draft, and they could not enter the Haihe River at all unless the tide was full. All Yang Qing can do is to use small boats to carry soldiers north along the coast, and our fortress in the military grain city is enough to deal with it, and the cavalry on the north bank will carry mountain artillery guerrilla attacks to block it.

In short, it's dragging.

It dragged on until King Yu broke through Zhengzhou.

At that time, the 400,000 troops of the allied army of the Qing Dynasty and Li Zicheng were in the Huai River, and all Yang Qing could do was to withdraw the army and then negotiate peace. ”

Hong Chengchou said.

At this time, the Ming army had already captured Jinan.

After all, Jinan is a lonely city, surrounded by a circle of twenty-four pound siege guns, and the main force of the Ming army of two armies is besieging it! For the Qing Dynasty to stick to Jinan for all these years, the king of Shuncheng County, Le Ke Dehun, said that he lit a fire, anyway, the 10,000 Qing athletes in Jinan were wiped out.

Moreover, the canal has begun to thaw, the Ming army in Dongping has begun to move north, and the battle of Dongchang is about to begin.

Li Zicheng on the southern line came to Yingzhou.

The Qing army on the northern front was still dealing with the attack of the Ming cavalry on the one hand, and attacked Zhengzhou and Kaifeng on the other hand, and the Ming army of Guide attacked and harassed Yifeng, but because the Lingxin of the Yellow River had begun, the main force of the Ming army in Xuzhou was still unable to move north. And Zelu's Jiang Hao is still waiting, this bastard has no hope, he doesn't betray the Qing Dynasty, even if he burns high incense. When it can be said that the tripartite wrestling was stalemate, Yang Qing suddenly came to Dagukou, making it clear that he was scaring people and forcing the main force of the Qing army of Duoduo to return to defense.

"Hong Qing is reasonable, since this is the case, let this thief run rampant for a few days!"

Dorgon said.

Of course, he didn't really want to fight Yang Qing to the death.

The regent is still very sober, especially after the lack of male hormones, he is now more and more calm, although he goes to ravage Yang Qing's wooden statue by various means from time to time, but he also knows that he must not face real people.

That demon is truly terrifying!

"The order, Yanjing and the surrounding flags to 15 to 60, all armor to carry out the army, in order to reinforce the king of Yu, this is the Qing Dynasty war, the only way to go all out, and select the strong women of each banner to hand over to the commander of the nine gates, in order to maintain order in the city. Ordered to be the king of the county, Boluo, the king of Anjun, commanded the two yellow flag guard battalions and the infantry battalion under the jurisdiction of the commander of the Nine Gates, and reinforced Dagukou to resist the Yang thieves! All the Qing Dynasty are the pillars of the Qing Dynasty, regardless of the flag and the Han are one, now is the most critical juncture of my Qing Dynasty, this king and the Qing should work together to overcome this difficulty, and the future wealth and Qing will be together! ”

Dorgon said.

The ministers were about to echo when a eunuch quietly walked up to Dolgon's side and whispered a few words.

Dolgon's face changed immediately.

"Waste, it's just a bunch of waste, the fort built by the imperial court with seven years of painstaking efforts, they didn't even survive three days? Ordered Bolo to immediately reinforce the army grain city, behead Bashan on the spot to show the public, and those who escaped from the battle will be beheaded! ”

He slapped the table and said angrily.

Because the range of movement was too large, and the beard on his mouth was not strong enough, as soon as he finished speaking, one of them drooped down, and Dorgon was so angry that he simply ripped it off. The pillars of the Qing Dynasty on the main hall hurriedly lowered their heads, but they were still a little shocked that Bashan, the commander of the 7,000 Eight Banner Army, lost the Dagu Fort in just three days. That's seven years of hard work in the Qing Dynasty, there are more than a dozen 10,000-pound cannons alone, and more than 200 cannons and small cannons, but they didn't even last three days?

However, Bashan, who is about to be beheaded, is really wronged!

He wants to hold on!

But in the face of the flowering bombs falling overhead, what did he do to guard the rocket? The Dagu Fort is not a closed fortress, it is nothing more than a large earthen platform, with a thick parapet wall on top, and a layer of infantry defense treads on the top of the parapet, and open gun emplacements below.

How does this thing deal with flowering bombs?

"This kind of fort really doesn't work!"

Zheng Chenggong stood on the occupied Dagu Fort and looked at the heavy brick walls around him and said.

And behind these brick walls, a heavy artillery discarded by the Qing army is firing, and even the mortars of the Ming army are also firing, including the naval guns on the sea outside, their goal is very consistent, that is, the north battery on the other side of the Haihe estuary. Dutong Bashan, who was stationed at Dagukou, did abandon the South Fort and ran to the Military Grain City, but the defenders of the North Fort did not run, and these heroic Eight Banners Divine Army athletes were resisting stubbornly......

This is indeed surprising.

I have to say that the athletes of the Divine Army are reliable!

Of course, the artillery left behind by the South Fort and the artillery of the Ming army will fulfill them, and their batteries are constantly shattered under the bombardment of those 10,000-pound cannons here, and they are also crushed in the explosion of the Ming army's flowering shells.

They don't have 10,000-pound cannons.

This side is the main battery, they are only protecting the main battery, and their shells can't penetrate the parapet on this side at all.

These large blue brick parapet walls are amazingly thick, not to mention their Hongyi cannons, even the Ming army's eighteen-pound naval guns are directly fired, and even the battleship's twenty-four pound short and heavy guns are useless, I am afraid that even the army's Shenwei invincible general cannon may not be able to chisel through. The hapless Eight Banners Divine Army on the North Fort were constantly bombarding this side in vain, watching their shells make craters on it, and then watching the shells of the Ming army fall overhead to harvest their lives......

I guess they are looking up to the sky and screaming angrily!

However, this does not mean that the fort is strong enough, its parapet is indeed impregnable, but the problem is that it has no protection above its head, and there is no protection behind it. Even the barracks inside the parapet wall have no real protection, and at most there is an underground ammunition depot, so that the flowering shells that fall from the sky can easily fall in and harvest the lives of the defenders......

Including on the gun emplacement.

It is true that the Qing army here is not about to collapse, after all, their defeat is a dead end, and they really hold on, which can be testified to by the blood on those cannons.

However......

They still only lasted two days.

"It's just not science!"

Yang Qing said.

"The fortress must not only look at how thick the walls are, it must be considered comprehensively, the outer walls must be as thick as possible, but the gun emplacements must be in a ring sinking into the ground, no parapet wall can be stronger than the earth, and each annular gun emplacement must be connected by tunnels, or even simply tunnels. Nothing else could be seen from the sky except the gun emplacements, even the soldiers' barracks had to be underground, and if possible, even the cannons had to be hidden in the forts.

That's what a fortress is called.

It's just a turret at best!

Not even the Europeans' forts, their ones are slightly better, but they still can't bear the flowering bombs, our black powder is weak, and the fortresses can still hold up, but the flowering bombs loaded with new explosives are not what the fortresses can carry. In the same way, our current steel is too expensive to cast shells, if the steel is cheaper in the future, the steel flowering shells used for casting special field guns can be punched into the shell of the fortress and then exploded, then the fortress will be wasted! ”

He continued.

Nitrocellulose is already there.

Picric acid is even already being trial-produced.

But

It's all in the lab.

Industrialization or something, at least in Yang Qing's opinion, there is no hope for ten years.

He is now just starting to experiment with sulfuric acid production.

Also in the lab.

Without the industrialization of sulfuric acid, there will be no nitric acid industrialization, and without the industrialization of nitric acid, there will be no explosives industry, everything must be carried out step by step, first using the nitrification method of sulfur and saltpeter to solve the sulfuric acid industry, and then using the reaction of sulfuric acid and saltpeter to produce nitric acid.

And it has to be Chilean saltpeter.

This is the No. 1 project of Daming Future Tianzi.

Don't expect to synthesize ammonia, that thing has to be high temperature and high pressure plus catalyst, whether it is a high-pressure tank or a catalyst is very unrealistic, the catalyst of the Haber method is osmium, modern iron catalyst is used, as for the synthesis of ammonia to nitric acid, platinum rhodium alloy net. Therefore, it is impossible for industry to reach the sky in one step, and if Yang Qing wants to develop, he can only take the road that the Europeans have walked out with more than a hundred years of history. In short, he still honestly played the lead room method to make sulfuric acid, and then went to mine Chilean saltpeter and use the sulfuric acid with the amazing sulfuric acid consumption of corrosion and saltpeter method to make nitric acid!

Strive to be able to use nitrocellulose within 10 years.

As for the field artillery flowering shells......

In fact, this can already be manufactured, but the cost is too high, and the cast iron flowering bullet cannot withstand the chamber pressure.

But the cast steel ones can.

However, the crucible method of steel is reluctant to even make the barrel of a gun! With this kind of steel-cast cannonball, it's almost the same as using bronze cannonballs! Until now, the price of crucible steel is still not cheaper than copper! Even if Yang Qing's cast iron technology has made great progress, at present, he only dares to use cast cast the flowering shell of the mountain howitzer with cast iron! This is already a great success, the howitzer that the Europeans called at this time is actually about the same as the mortars of the Ming army, and it will take another hundred years to reach the level of the mountain howitzers of the Ming army. Their shell casting technique is not good, so far they do not cast a hollow ball in one piece, but cast it in half and then weld it together with molten liquid.

But the Ming army's mountain howitzers fired monolithic cast flowering shells with wooden stocks.

And there are also new grenades.

That is, in the time of Napoleon, the British often used to bombard the cuirassiers, a cannonball with a fuse and gunpowder, which was filled with a large package of bullets, flew above the target's head and exploded.

This is good for dealing with cavalry clusters.

"Protector, shouldn't you inform Li Zicheng?"

Zheng Chenggong reminded Yang Qing.

"No need, he has no fewer spies in Beidu than Jinyiwei, at this time, it is estimated that someone has already reported to him, let's just leave him alone, just do what we should do!"

Yang Qing said.

Li Zicheng's spies in the northern capital are indeed no less than Jinyiwei, in fact, the trade between the two of them has been going on before, and Li Zicheng has not done anything as long as he makes money over the years. The sugar, tea, and the like needed in the Mongolian steppes were basically shipped from him, and since he sold them to the Mongols, of course, he also sold them to Dolgon, and they were all the same anyway. In this case, almost all the merchants in Guanzhong were openly active in the northern capital, and almost every one of these people was Li Zicheng's spies, and they were originally members of Li Zicheng's state-run commercial commune.

"This great achievement in recovering the northern capital, it's really cheap to give it to him!"

Zheng Chenggong said.

In other words, this liberation of the northern capital is famous in history.

is so cheap Li Zicheng, he still feels a little lost after all.

"That's going to kill a lot of people, hundreds of thousands of banner people in the northern capital, they will resist desperately, they will kill the northern capital into a mountain of corpses and a sea of blood, Li Zicheng's group of arrogant soldiers and fierce generals are also hidden dangers, let them die in the northern capital is also a worthy death!"

Yang Qing said with a sneer.
