Because during the Chongzhen period, the navy's bird hull became larger and the eight rows on both sides of the ship were cancelled, leaving only two large rows on the stern.

Therefore, when the Yellow River rises, the speed of the wind cannot be faster.

The navy also specifically determined that under the conditions of the wind, bird boats can travel about thirty miles within half an hour as fast as half an hour [the speed is about 8 knots].

This speed is already the extreme speed.

If there is no wind, the speed will be very slow by just urging the oar.

In this way, the navy warships will be exposed to the guns of the Jiannu Red Yi cannon for a long time.

Chongzhen immediately ordered Zheng Sen: "Zheng Sen, have you prepared the three-color lanterns of the navy? Hurry up and send a signal to the navy and ask them to retreat to a safe distance and stop forcing them to break through again."

Zheng Sen quickly took the other two scholars to hang three-color lanterns.

Seeing the three-color lanterns hanging on the Ninth Peak, the navy warship immediately turned around and retreated.

However, it takes time to turn around, and I still cannot escape the threat of the Jiannu Red Barbarian cannons, so the sound of cannons still rumbling on the river surface, and warships will be cannons from time to time.

The Ming army navy suffered a great loss this time.

At least ten ships were lost.

...

Duoduo was also awakened by the sound of cannons and quickly got up in his clothes.

Soon, He Luohui, Waxinga and other generals of the Inlaid White Banner arrived one after another.

Waxinga was seriously injured in the Battle of Yunlong Mountain and was about to recuperate for several months. Her injuries finally recovered. She has been shouting for revenge these days, threatening to rush to Yunlong Mountain again.

Duoduo naturally ignored him. What kind of revenge is he?

I didn't want to take revenge after suffering such a great loss in Shanyang.

Duoduo understood clearly, and the Ming army was still very fierce in defending the city.

Soon, Shitu came to report: "Master, it was the Ming army's navy who arrived."

"Have the Ming Army Navy arrived?" Duoduo asked with a narrow expression, "How is it? Did you stop them?"

"Master, please don't worry." Shi Tu smiled and said, "I just went to the river to see it. The turret we built was very solid. Minggou's naval warship could not do anything to us at all. In this artillery battle just now, our turret and red-clothed cannon were unscathed. Minggou's naval warship had several sunk by us, and then he retreated in ash."

"Okay!" Duoduo said happily, "It seems that Hong Chengchou's method is still effective. Even if the Yellow River is there, even if Minggou has the benefits of the navy's warship, he still cannot enter the encirclement. He can't even send a grain of food in it."

While he was talking, Dongfang showed white fish belly and then rode over with a fast horse.

"Report..." Along the distance, the messenger on the horse's back roared loudly, "The army of the emperor's father and the regent have arrived fifteen miles away, so Prince Yu will go to greet him immediately!"

After all, they were brothers, Dorgon only asked Duoduo to pick him up alone.

Other princes such as Luo Luohun, Luke Dehun, and Guermahun would not have this opportunity.

"Did the Fourteenth Brother actually march overnight?" Duoduo's expression condensed and he shouted immediately, "Waxing, Bayala, who is inlaid with white flags, follows me to protect the frame."

"Yeah!" Waxinga agreed with a loud promise.

Soon, Duoduo took Bayala with the white flag inlaid out of the camp.

At this time, the sky gradually became brighter, and it can be clearly seen that short tender green buds had grown out of the ground outside the camp of the white flag. This was the freshly planted spring wheat.

By the way, Jiannu is almost out of food.

The freshly planted spring wheat must not be able to provide Jiannu’s military rations.

So in the next three months, nearly four months, we will rely on Beijing for supply.

[Note: The growing period of spring wheat is about 100 days, sown in May, and harvested in September]

Dorgon, with 30 Niulu 9,000 Eight Banners soldiers from the Yellow Banner, and the newly recruited 20,000 Han troops, escorted 300,000 shi of military rations along the canal, heading south along the waterway to Yanzhou Prefecture.

However, after entering Taizhuang Gate fifteen miles north of Xia Town, Dorgon decisively ordered the navy to return, and then asked more than 100,000 troops to accompany the army to coat and push the chicken bus, and the wheelbarrow went south around Xia Town overnight.

...

Looking at the endless torches of Jiannu, especially the hundreds of thousands of chicken buses and wheelbarrows pushed by the army, Huang Degong's generals were eager to try, and they all shouted that they would launch sneak attacks at night to rob Jiannu's military rations, and even if they couldn't grab them, they would burn the food.

To be honest, generals such as Huang Shi'an and Tian Xiong were all a little bit arrogant.

In the great victory in Xiazhen last year, they defeated the Yellow Banner, which is known as the strongest combat power among the Eight Banners of Jiannu, so they didn't take Jiannu seriously.

But Huang Degong's mind was still very clear.

Although he won a big victory in Xia Town last year, it was just a side-level army in Jiannu. Moreover, he was able to win at that time, which had a lot to do with Jiannu's carelessness in underestimating the enemy. If Jiannu did not underestimate the enemy, he would definitely not be able to win.

And that's a defensive war. If it's a field battle, the Ming army is basically no different from a death sentence.

Besides, before Jiannu went south, Chongzhen also specifically instructed him to let him just guard Xiazhen, and he didn't have to worry about anything else. Unless he had his order, it was strictly forbidden to send troops without authorization.

Huang Degong said in a deep voice: "Tell me that I will order you, who dare to fight without authorization, will be killed!"

Huang Degong's generals soon spread throughout the army, and the generals of the ten towns under his command could only give up their thoughts.

At this time, Yang Ponu, who had been promoted to the chief executive, suddenly said, "Marty, remember that the emperor said that Jiannu had only had more than 100,000 soldiers in total? There were more than 200,000 Jiannu troops outside Xuzhou City. Why are there so many Jiannus coming now? There are no sight in this queue at a glance, and at least there must be more than 100,000 people, right?"

"At least 150,000!" Huang Degong made an accurate estimate.

Then he said, "However, these are not real slaves of Jiannu, they are all accompanied by the army."

Yang Ponu said, "Mr. Marquis, you can't be all accompanied by the army, right? There must be real slaves? By half, how many real slaves have been transferred? Then isn't Beijing City empty?"

"What does it mean?" Huang Degong turned around and stared at Yang Ponu.

"Uh, ah?" Huang Degong's reaction was so great that Yang Ponu was startled and said hurriedly, "It's not interesting, Marquis, I just want to say that Jiannu is really brave and is not afraid that we will attack his lair."

Yang Ponu really said casually, but Huang Degong could no longer be calm after hearing this.

Yes, if Jiannu really engulfed all the troops from all over the country to besiege Xuzhou and confront the emperor, wouldn’t Beijing be empty? If he led the border troops of ten towns and headed north at this time, starry night?

Thinking of this, Huang Degong could no longer calm down.

Huang Degong said to Yang Ponu: "Yang Ponu, do you dare to go to Xuzhou?"

"Why don't you dare?" Yang Ponu said, "Although Jiannu surrounded Xuzhou City and was surrounded by water, there were still night-delayed troops within fifty miles around, but if you want to enter Xuzhou City, it would be a piece of cake."

"Okay!" Huang Degong waved his hand and said, "Come here."

Huang Degong whispered a few words in Yang Ponu's ear.

Yang Ponu immediately bowed and said, "Take the order!"

Then he turned around and walked away quickly.

...

In fact, this was really Dorgon's plan to lure the enemy.

In order to lure the Ming army to attack, Dorgon even transferred the flag head of the inlaid yellow flag.

Of course, if Ming Jun really came out, he would find that the coated slave who was pushing the chicken bus and the wheelbarrow was actually not the real coated slave, but the flag-teacher who was wearing yellow flags.

Seeing that the Ming army was unmoved, Dorgon sighed: "What a pity, the Ming army refused to come out."

"Master, this is actually an expected result." Hong Chengchou comforted Dorgon and said, "The Ming army has completely lost the courage to fight in the field since the Songshan Battle and has not yet recovered. However, it is precisely because the Ming army lacks the courage to fight in the field that our Qing soldiers were able to concentrate their forces to surround the city of Xuzhou. Otherwise, once the Ming army in Shandong, Xiazhen, Pizhou and even Huai'an Prefecture goes north, Beizhi and even Beijing will face a huge threat, and it will be troublesome at that time."

"So, it's better to eradicate the Ming army in Xiazhen first. Keeping this route with the Ming army is ultimately a threat."

Dorgon frowned and said, "And if Xiazhen is not taken down, the canal will not be opened. The navy's grain ship can only go to Taizhuang Gate. Next, it will only rely on the chicken bus and wheelbarrow to transport it. This time there is no problem with the army's coat, but the next time I transport grain, I will not be coated with the army, so I have to go one more trip at that time."

This time when he went south, Dorgon brought 150,000 coats.

The 150,000-plus coated people came to Xuzhou and Guide Mansion to farm.

In order to win the Xuzhou War, Dorgon really took his best efforts. Not only did he transfer almost all the troops of the Qing court to the Xuzhou battlefield, but even more than 200,000 yuan of coats were transferred to Xuzhou.

This is really a dedication to the whole country, and it is to decide the life and death of the Ming Dynasty.

From this point of view, it can also be seen that Jiannu’s national strength is actually really weak.

It has been fifty years since the old slave raised his troops, but when Jiannu encountered a decisive war, he still had to devote all his troops to the whole country to have a chance to win.

This is how the Battle of Sarhu is.

The same is true for the Songjin Battle.

The Shanhaiguan War is still the same.

The battle in Xuzhou is still the same.

That is, the combat power of the Eight Banners soldiers, or the cavalry and shooting, were strong enough, otherwise, the weak national strength of Jiannu would have been wiped out by the Ming Dynasty for a long time.

"Master, it's not a big deal."

Ning Wan, I said: "The Ming army in Shandong, Xiazhen, Pizhou and Huai'an Prefecture have not had the courage to go north. After many years, the Ming army is a coward, which is well known to everyone. As for the servants to run more errands, it is all right. For the sake of our Qing Dynasty, it is nothing more miles away, and I would rather die if I run away."

"You can talk." Dorgon smiled and turned his gaze to the side of the road.

I saw that there were pieces of arable land on both sides of the road. It was obviously cultivated last year, but it is still deserted now.

"Master, look, the fields here have been reclaimed." Fan Wencheng said, "If this happens, the harvest will be guaranteed, otherwise the food rations will be really tight this year."

This is how land is. Only when it is cultivated and planted frequently will it become mature land, and the yield will be higher.

After years of abandonment, the farming process suddenly resumed, which was similar to the raw land, so the yield was not high. In addition, the farming technology of Jiannu was lagging behind the Ming Dynasty, so the yield was even lower.
To be continued...
