Chapter 997

Outside Dingtao City, Dugu Ba and Dugu Tian brothers are under the protection of their own soldiers to observe the situation around Dingtao city. The three Dugu brothers were the first to join Huangfu Chaobo. Although they were loyal, their abilities were limited. In addition to their special arms, Huangfu Chaobo wanted to hide their cards, so they had little chance to lead the troops.

Since joining Huangfu Chaobo, the three brothers have only shot twice, but each time has brought great surprise to Huangfu Chaobo. For the first time, it was the escape tunnel of the changshe war, which made Huangfu Chaobo relieve the crisis of changshe city and get a lot of war achievements. Finally, he got Zhu Jun's appreciation and was accepted as a student. The second was the second Puyang battle a few years ago. With the help of the tunnel, Zhao Yun quickly entered the city and defeated Cao Cao's army.

However, many of the warriors who took refuge after their three brothers were brilliant in the past few years, but only Dugu Xiong, the eldest of them, became the general of Zhongying, and the second and third were only school captains, which made the three brothers very unwilling. This time, they finally had the chance to lead the army. They had already discussed it before they went out to the army. This time, they must fight Seize the opportunity and make great achievements.

After getting the order from Huangfu Chaobo, the two brothers first observed around the whole city under the protection of their own soldiers, and roughly looked at the surrounding conditions. At the same time, they made a careful observation of the surrounding terrain and waterways. Along the way, the two men still took out a compass from their arms and compared everything. They often took a shovel from their own soldiers and dug holes in the ground, carefully observing the soil in the pit.

After nearly two hours of tossing around, the two brothers finally observed the whole city. They looked at each other and saw a glimmer of joy in each other's eyes. After careful inference, they found that the conditions around Dingtao city were completely in line with the conditions of tunnel attack, and they also found several defense defects in the wall.

"Second brother, the northeast corner and northwest corner of the city wall are suitable for tunneling. Where do you think we should start?" Dugu Tian looked at his brother and said,

"don't worry, I can see that these two places are more suitable. Let's take a closer look. The tunnel needs to be excavated from a few miles away. In this way, let's go a little further." Dugu Ba thought for a moment and then said,

as he said that, the two brothers got on their horses again and ran several miles northwest of the city wall. They didn't stop until six miles away. Along the way, there was just planted grain everywhere. Dugu Ba stood on a hill and looked back to the direction of Dingtao city. He had a conclusion in his heart. Just now they passed a forest, which is only four miles away from Dingtao city. There is only a relatively large forest around, and the location is a little higher. The soil there is also suitable for digging tunnels. If there is no better location in the East, it should be the most suitable place.

"Come on, let's go to the northeast of the city and have a look!" With that, Dugu Ba took the lead and went to the northeast of Dingtao city.

When it was dark, they finally rushed back to the camp of Zhengdong army in the west of Dingtao under the protection of their own soldiers. As soon as they got back to the camp, they rushed to the army tent of Huangfu Chaobo.

At this time, Huangfu Chaobo and Pang Tong were having dinner. When they saw Dugu brothers coming in, they said with a smile, "have you had dinner yet?"

They shook their heads and were about to report the results of their observation today. However, Huangfu Chaobo said, "don't worry. Let's talk after dinner."

Then they added two more bowls and chopsticks. They were moved. After thanking each other, they sat down to have a meal.

Because there was something in his heart, the Dugu brothers finished the dinner in a hurry, then put aside the dishes and chopsticks, quietly waiting for his master to finish his meal.

Seeing their appearance, Huangfu Chaobo also laughed and said, "are you sure you've eaten well?"

"It's done!" They answered in unison;

"all right!" Huangfu Chaobo put the food in the bowl into his mouth in twos and threes, and said, "tell me what you've got. I think you should have some good news for this general."

Dugu Ba stood up and said, "Congratulations, Lord. Dingtao can indeed attack with tunnels. His subordinates have carefully examined the whole city. Except for Linji water in the south, which is not good for tunnel excavation, the other three walls can dig tunnels. However, according to their suggestions, they can dig tunnels in the northwest corner of the city wall."

"Reason!"

"A few of my subordinates have carefully examined the soil in the northwest corner of Dingtao and found that it is the most suitable place to excavate tunnels. The soil here is moderately soft and hard, which is convenient for excavation, but it is not easy to collapse. Moreover, there is no river passing through this area, and the groundwater is very deep, five or six feet deep. If it is excavated from here, it should be the easiest place."

"Another point is that the north gate of Dingtao is slightly to the west, and there is a passage to the city in the northwest corner. If the gate breaks into the city, it only takes hundreds of steps to quickly attack the city wall through this passage."

Huangfu Chaobo nodded and said, "how are you going to arrange it? How do you need ben to cooperate?"

It's not the first time I've seen them dig tunnels. Huangfu Chaobo also knows that they need other support besides their own taxi soldiers. That's why he asked."My subordinates are going to excavate three channels at the same time. Each channel is divided into four waves by 1000 soldiers. At the same time, they need 2000 people to help transport soil and wood."

"How long will it take?"

"In ten days, we can dig these three tunnels for the Lord."

"Ten days is too long. I'll give you 5000 people for each tunnel. Can you dig it in five days?"

"Lord, this can't be done by increasing the number of people." Dugu Ba said with an embarrassed face, "Minfu's role is only to transport soil. The tunnel can't be too big, so the speed of Minfu walking in it will not be fast."

Huangfu Chaobo has also seen them dig tunnels. The soldiers in front of them are responsible for supporting the tunnels with logs to prevent them from collapsing on the way. The role of the folk men is only to transport the soil they dug out. The tunnel is not wide, but just two people walk side by side, and they need to bow slightly, so the speed really can't be too fast.

Huangfu Chaobo still remembers that time when he was in Puyang, he stood at the entrance of the tunnel and watched the folk men go in and out from there. It was like seeing teams of ants carrying things in and out of the cave.
