During the battle of Yin, the Han army suffered little casualties. Most of the soldiers who fell to the ground successfully escaped. Only four soldiers on the hot air balloon injured by Wei Yan fell into half-splitting and were easily harvested by the Wei cavalry that followed.

The Wei army was not seriously injured and suffered heavy casualties. No shells were used in the city in the middle of the night. Moreover, the Wei army knew how to avoid it. Instead, they did not rush up in a swarm and scattered very wide. Except for the particularly unlucky ones, everyone returned intact.

This unique night attack lasted for a long time, the casualties of both sides were single digits.

After the war, Cao Ang came out with his pants, ran to Pang Tong and asked, "How is it, how many have he killed?"

Knowing oneself and enemy will never be defeated. Both he and Zhuge Liang knew each other's old secrets. One knew that the other party would attack at night and took precautions in advance. The other knew that the other party might be prepared and attacked with great caution. They retreated immediately when they were inappropriate. The two sides fought in harmony.

Pang Tong smiled bitterly and said, "Zhuge Villager is too cautious. If he guessed correctly, he now has a mentality of not seeking merit but seeking nothing wrong. It is difficult to deal with."

Being careful at any time is a noble quality. Although you don’t know how to make great achievements, you won’t make fatal mistakes.

Later generations said that Zhuge was cautious in his life. Zhuge Liang was cautious, so he was as stable as an old dog.

With the defense of Bowang City, the traditional siege method cannot be defeated at all, and even if the losses are captured, it is unbearable. If you take Zhuge Liang, a defender who is known for his prudence, you will feel so sad.

Cao Ang's eyes rolled around for a few times, and bad water surged into his heart again, and he asked, "Is the source of the moat blocked?"

The Bowang moat is used to irrigate the Han River. If the Han River successfully flows into the river, it is necessary to create a gap. In order to prevent the river from smelling and causing plague, it is necessary to build several more gaps to make the water live. When Huang Zhong left, Cao Ang asked someone to block all the gaps in the river and didn't know what to do.

Pang Tong nodded and said, "It's been blocked for a long time."

Cao Ang smiled and said, "Since that's the case, you can use a secret weapon."

Pang Tong's eyes lit up and he said in surprise: "Do you still have secret weapons?"

"Of course, it's useless to call my nanny?"

Cao Ang turned his head and ordered Hu San, "Go and carry the things up."

"Here."

Hu San took his men away, and soon he returned with his guards carrying two rectangular heavy objects.

Pang Tong looked closely and said in confusion: "Isn't this a generator? What's the use of bringing this thing?"

He was very familiar with the square object in front of him. It was the generator case that he had seen for a long time. Another one was similar to the generator case, and I don’t know what it was for.

Cao Ang explained: "This is a generator, the other is a water pump, which is used for pumping water. Let's drain the water from the moat. I'll see what Zhuge Villager should do."

Drain the water from the moat?

Pang Tong's head was buzzing.

I really want to ask, "Your Highness, what are you in your mind? What do you think so strangely?"

Throughout history, China has fought many years of wars, but I have never heard of anyone doing this.

However, if it can be drained, it seems to be very fun, although it seems useless.

Pang Tong was also the one who was not interested in the big deal when watching the fun, and said excitedly: "How to operate it?"

Cao Ang glanced at Tianse and ordered: "Hu San, take advantage of the darkness to throw the water pipe into the moat.

Hu San took the order and ran towards the moat with several guards pulling a hose as thick as a calf.

The nurse dare not say anything else. The essential tools for traveling to monks are quite sufficient. There are dozens of hoses as thick as calves, each of which is more than 5,000 meters long.

The military camp and the moat were ten miles apart, and the pipes of five thousand meters were just enough, but I didn’t know if the water pump could be brought up at such a long distance.

It is now five o'clock in the morning, which is the darkest moment of the day. There is no moonlight and the sky is pitch black, which is not much better than not seeing your five fingers.

Zhuge Liang had already withdrawn his troops and returned to the city. Although there were defenders and torches on the city, it was still not easy to see a few figures clearly.

Hu San and his team trotted all the way, and soon arrived at the moat, threw the water pipe and the heavy objects on the head of the pipe, and turned around and ran away, returning to Cao Ang and said, "Your Highness, you've done it."

Cao Ang came to the generator with his hands, started it and turned on the water pump after a while, and then waited patiently.

Cao Ang couldn't guarantee whether the water pump could be pumped up for a five-kilometer water pipe. Even if it could, the startup time would definitely be quite long. Cao Ang was mentally prepared.

But Pang Tong didn't. He only heard the generator and the water pump quarrel, and there was no water coming out. He couldn't help asking: "Your Highness, this thing called a water pump can really pull out the water from ten miles away. Why didn't there be any movement?"

Cao Ang said angrily: "What's the hurry? I didn't guarantee you 100% of all. I just said it's possible, just wait, it's not time for you to change shifts."

After waiting for a quarter of an hour, Cao Ang felt distressed when he held the outlet of the hose and didn't see the water coming out. It was indeed unreliable. He was about to turn off the water pump and ended this embarrassing journey. Yang Xiu and Sima Yi walked over hand in hand and asked curiously: "Your Highness, Shi Yuan, what are you doing?"

Pang Tong opened his mouth and was about to explain, but Cao Ang hurriedly blocked him and said, "It's okay, I'm sleeping for a long night, come out and listen to the music."

Yang Xiu: "..." Sima Yi: "..." You call the noise of the generator music. How leisurely are you in the middle of the night?

Before the two of them could think of how to answer, the hose in Cao Ang's hand suddenly trembled, and a stream of water that was as thick as a calf sprayed out with a thud, spraying Yang Xiu and Sima Yi on the spot. The impact of the water flow was quite strong. The two of them were caught off guard and were directly washed backwards. Yang Xiu was tripped by something and sat on the ground.

The water dump did not end because he was tripped, but instead became more and more violent. Cao Ang was startled and quickly moved the water pipe away.

Pang Tong was stupid and murmured to himself: "Really... really pulled out?"

Yang Xiu and Sima Yi were even more stupid. He was stunned for a long time as if he had been immobilized and asked, "What's the situation?"

Cao Ang smirked and explained the working principle of the water pump for the two of them.

The two of them came to their senses after hearing it for a long time. They didn't even care about the clothes they had been wet and stuck to their bodies. They rushed to the water pump and observed carefully without any effort.

After watching for a long time, he couldn't understand it. Yang Xiu had to pretend to understand, "A magical artifact, Your Highness, this is a magical artifact. If you have this thing, why canals be built? In the future, just irrigate the farmland and put it on the water pump."

Sima Yi retorted: "Don't talk about this useless. How many counties and towns in the Wei Dynasty? Where can there be so many water pumps for you to squander?"

Cao Ang smiled and said, "This is simple. Just build a factory that specializes in water pumps. Are you interested in buying one?"

Yang Xiu and Sima Yi's eyes lit up at the same time, and this kind of magic weapon could be sold at a glance.

Compared to Yang Xiu, who was jealous of money, Sima Yi was more calmer and frowned and said, "The idea is good, but that is the future. Let's take a look at the front of you first. Your Highness, the water from the moat has been drained, but where are you going to put it, you won't plan to flood our own military camp, right?"
