If everything goes well, a flintlock gun should be made in two months.

It has been a year and a half since March last year. During this time, Chongzhen was either running for his life, fighting, or scheming with the Donglin Party.

After being busy for such a long time, I can finally free my hands to click on the technology tree.

Chongzhen added the first technological point to the flintlock gun, which was also the right choice.

Because the flintlock gun must be considered an epoch-making weapon. Once a large number of flintlock guns are equipped in the army, and supplemented by powerful artillery units, it will be enough for the cavalry to change from a main combat arm to an auxiliary arm.

Since the emergence of the flintlock gun, it has become a wishful thinking for backward civilization to defeat advanced civilization.

The traditional crafts of nomadic peoples or barbarians changed from "threwing grass in the valley" to "singing and dancing".

…

At the same time, Dorgon also returned to Beijing in "triumph".

Calling it a triumph, Dorgon is just trying to put gold on his own face.

This southern expedition brought little tactical losses to Jiannu.

The hardest hit this time were the Zhenglan Banner and the Xianglan Banner, but these two flags were not originally the main force of the Eight Banners. As the mainstay of the Eight Banners, the Xianghuang Banner and the Xiangbai Banner actually did not suffer any injuries.

But from a strategic perspective, Jiannu suffered a disastrous defeat this time.

The biggest strategic goal of this southern expedition was to destroy the Ming Dynasty in one battle.

Even if the Ming Dynasty cannot be destroyed at once, the Ming Dynasty's northern defense line must be destroyed.

But now this strategic goal is completely bankrupt. After fighting the Ming army along the Huanghuai line for more than half a year, the Ming army's Xuzhou defense line remained firm. And after this battle, the Ming army's Huanghuai defense line was completely formed.

If I want to launch the next war to destroy the country, I'm afraid it will be far away.

What made Dorgon even more angry was that,

Not only has the biggest strategic goal not been achieved, but the secondary strategic goals have also not been achieved.

After realizing that there was no hope of seizing Xuzhou, Dorgon decisively changed the combat goal, replacing the destruction of the Ming Dynasty in one battle with the destruction of the Ming Dynasty's military presence in Shandong, and eliminating the flank threat of Beizhili.

Of course, by the way, we will hit the grass valley and make up for the losses in the Xuzhou battlefield from Shandong.

This goal of clearing grass and valleys was accomplished. After Duduo's army entered Yanzhou, they burned, killed, and looted, and robbed nearly one million people, as well as a large amount of grain, livestock, and goods.

Especially the looting of the Yanshenggong Mansion in Qufu was really a bloodbath.

The treasures accumulated by Yan Shenggong's mansion for hundreds of years were all returned to the two white flags.

In fact, the gains from Duke Yansheng's Mansion alone were enough to make up for the losses in the Battle of Xuzhou.

Duduo knew about the allusion of being as rich as the country, but he had no idea about it. It was only after he robbed Yan Shenggong's Mansion that he finally understood what it meant. Yan Shenggong's Mansion was really as rich as the country.

But the gains from establishing slaves did not end there, and there were very few military gains.

Faced with the heavy troops pressing down on Jiannu, the Ming Dynasty Governor of Shandong Province Wang Jiayan and Admiral of Shandong Military Affairs Hu Xin split into two groups and retreated to Mengyin and Linqu respectively, unable to hold on.

Duduo's army spent a lot of effort to transport Hongyi cannons and finally blasted Mengyin City away. In the end, Wang Jiayan led the Ming army to retreat to Yishui before breaking the city. In short, they did not confront Jiannu.

Instead of being tough, they tried to use the terrain of the Yimeng Mountains and the fortified city to consume the slaves and fight a protracted war.

After a few battles, Jian Nu became a little unable to bear it.

Not only the two red flags, the two blue flags and the two yellow flags, but also the two white flags also gave rise to a feeling of war weariness. After all, the Eight Banners soldiers are also human beings. They have been fighting since the beginning of the year, and they have been fighting for more than half a year now.

The key point is that I haven't achieved a hearty victory yet, so it's impossible not to feel depressed.

Duduo realized the danger and quickly reported it to Dorgon.

Dorgon could only give up the second goal and directly fight.

However, before withdrawing his troops, Dorgon robbed all the remaining strong men, women and children in Yanzhou Prefecture and Jinan Prefecture, and executed all the old, weak, sick and disabled, and then took with him nearly one million people and a large amount of food, livestock and property.

When the cargo squad returned to Beijing, the entire team was more than a hundred miles long.

Because we had a lot of women and children with us, we walked very slowly.

From the end of July to the beginning of September, I finally returned to Beijing.
Chapter completed!
