The distance from Nanjing to Yangzhou is 200 miles, and the 30,000 Qing troops are simply not enough to besiege the entire city of Nanjing.

The news of the fierce battle outside Nanjing was quickly transmitted by the envoy to Yangzhou, and Chongzhen's concern for the battle situation was also brought with him.

I have to say that after experiencing hardship, Chongzhen's eager temper changed a lot, and he only described the critical situation in Nanjing to Chen Yue, but did not force Chen Yue to immediately fight with Duoduo to return to Nanjing. The implication is self-evident.

"With twice the strength of the Manchu Tartars, he fought against the fortified city, but he was defeated by the Mantars, and the corpses were piled up all over the field, and the Beijing camp that the Marquis of Zhenbei had trained for a year was like this."

Looking at the paperwork handed over by Chen Yue, Qian Fenglin sighed. The people of the Jiangbei Governor's Mansion have always been very dissatisfied with the imperial court's excessive attention to Jingying, and for more than a year, the silver allocated by the imperial court to the Yangzhou Governor's Mansion has not been confiscated by the salt merchants and sent to the imperial court.

Moreover, the ordnance produced by the ordnance workshop of the Nanjing Military Department was given priority to equip the Beijing camp, and the ordnance of the Pingnan Army could only be built by itself. These have made everyone complain about the court.

Chen Yue ignored Qian Fenglin's words, and just looked at Wang Yin, who had just come from Nanjing, with a happy face.

"Hengshan Gong, how are you doing in Nanjing?" Chen Yue asked with a smile.

Feeling that there is a lack of people around him who can discuss military strategy, there is only one Qian Fenglin to discuss, but the affairs are too busy. Chen Yue asked the imperial court several times to send Wang Yin to Yangzhou, and now he finally got his wish, and Wang Yin was appointed to serve as a political officer in Jiangbei and sent to Yangzhou.

"Hey, I've been busy all day long, and I'm so bored." Wang Yin shook his head and said with a wry smile.

Although the head of the household is in a high position and the affairs he manages are also very complicated, Wang Yin has to be responsible for various affairs such as fields, household registration, taxes, etc., although there are many chief officials under him to drive, but he does not dare to slack off.

"Yokoyama Gongzhicai is planning and strategizing in the military, and he is really wronged when he uses it in a place like the household department." Chen Yue said with a smile.

"Looking at the mood of the Hou Ye, he must have been confident in defeating the Mantars outside the city, and even if he comes to Yangzhou, he may not be able to play much role."

Wang Yin smiled.

"Hahaha, you still need Hengshan Gong to check and fill in the gaps to help plan." Chen Yue said and glanced at Chen Shi on the side of the guard, Chen Shi nodded, drove everyone in the arrow tower far away, and stood at the door himself. There were only three people left in the arrow tower, Chen Yue, Qian Fenglin, and Wang Yin, and Wang Yin knew that Chen Yue was going to tell his battle plan.

Looking out through the arrow tower, which is a foot higher than the city wall, the Qing soldiers who attacked like a tide and the people who were driven by the Qing soldiers to besiege the city as cannon fodder were densely packed like ants.

The moat had been filled by the Qing soldiers, and the northwest corner of Yangzhou City had cracked more than two zhang wide under the repeated bombardment of the red-coated cannons. The Qing soldiers are attacking along this crack.

However, Chen Yue had already prepared for this, as early as a few days ago, when the cracks in the city wall just appeared, he ordered the Yangzhou government to organize the people to rebuild a city wall after the cracks, and tens of thousands of people rushed to work day and night, with the bricks and stones prepared in advance, and built a thick city wall in a few days, and the two bread bricks were filled with rammed earth, and the thickness of the outer city wall was almost half a zhang shorter.

This inner wall also has a buttress and is connected to the outer city wall to form an urn city.

After the attacking Qing army broke into the crack, they were shocked to see that there was a city wall inside, and they were immediately besieged on three sides of the city wall in Weng City, arrows rained down, bricks, lime bottles, rockets, and 10,000 enemies threw them down, and the attacking Qing army threw down more than 1,000 corpses and retreated like a tide.

The gap that was originally opened by the red-clothed cannon of the Qing army turned into a trap, and Wang Yin nodded secretly, and the new students admired. However, he also knew that although this seemed simple, it required strong execution, and it was necessary to organize the people of the entire city to obey the orders of the government. Otherwise, it would never be possible to build such an interior wall in a short period of time, although it is only a few dozen zhang long.

is good at using the terrain and terrain to turn disadvantages into battlefields that are beneficial to himself, Wang Yin knows that this is Chen Yue's style of fighting.

But this time, he was really a little curious about how Chen Yue would defeat the 100,000 Qing army outside the city.

"Hengshan Gong, you know astronomy and geography, can you calculate what the weather has been like in recent days?" Chen Yue withdrew his gaze from outside the city and looked at Wang Yin fiercely.

When Wang Yin heard this, he looked at the sky along the door of the arrow tower, and saw that the sky was overcast, and the clouds were dark and thick, as if pressing on the top of the arrow tower.

"If the old man is not mistaken, there will be a heavy rain tonight and tomorrow at the latest." Wang Yin said affirmatively, not understanding what Chen Yue meant by letting him see the weather.

"The rain won't last long, a day or two at most." After thinking about it, Wang Yin said again.

This season's rain is like this, the rain stops quickly, and it is rare to even have a cloudy day, after all, the wheat harvest season will enter in less than half a month. The wheat harvest season is usually rarely cloudy.

Could it be that the Hou Ye is worried about the wheat of the people outside the city? Wang Yin thought for a moment and shook his head again. For the commander of the army, victory is the primary consideration, and the wheat that is about to be acquired is nothing at all, and Chen Yue will not pay attention to this at this time.

"When it rained heavily, the land outside the city was so muddy that the Mantars could not attack at all. However, the gunpowder is damp and cannot be used, so we can't attack out of the city. Qian Fenglin on the side shook his head and said.

The Pingnan Army now attaches too much importance to the use of firearms, and if the firearms cannot be used to level the air by 50 percent, the battle with spears and Manchu Tartars is even more long.

"Heavy rain is naturally not a good time to attack, but Hengshan Gong and Brother Fenglin must also know that fifty miles north of Yangzhou City is Gaoyou Lake. Not long ago, heavy rain fell on the entire Jianghuai River for several days, causing the water level of the lake to soar, and now it will rain heavily. ”

Chen Yue said, looking at Wang Yin without blinking. He came up with a strategy to break the enemy, but he didn't know if it could be realized, and he needed Wang Yin's help to plan.

Attacking the enemy with a lot of water, Wang Yin's eyes lit up when he heard this, and then they dimmed again. The idea is good, but unfortunately it is not realistic.

"Master Hou, ransom subordinates bluntly said, I'm afraid the strategy of water attack will not work." Before Wang Yin could speak, Qian Fenglin spoke.

"After all, Shao Bo Lake is fifty miles away from Yangzhou, and Shao Bo Lake is a low-lying place in the south, even if the embankment is dug up, it is really difficult to threaten the Qing army camp with the water of Shao Bo Lake flowing out for fifty miles."

In order to occupy a natural geographical advantage by attacking the enemy with water, it is first necessary to have sufficient water, and the water level must be extremely high and rush down in order to quickly crush the enemy.

And with the amount of water in Shao Bo Lake now flowing into a trickle even if it flows outside Yangzhou City, how much of a threat can it pose to the Qing army? There are many hills outside the city of Yangzhou, as long as the Qing army moves to the higher hills, they can avoid this flood.
