Xun Yu found Xu Zhen and asked Xu Yang to take five hundred soldiers with him, Xu Yang heard it, didn't say a word, and immediately ordered all the people to prepare to set off.

Xun You and his entourage, after making proper preparations, hurried to the outside of Xingyang City. And Huangfu Song led the army to wait until tomorrow to continue to set off.

Xun You, Xu Yu and his entourage, hurried for two days, and finally arrived at the foot of an unnamed hill fifty miles east of Xingyang City. But with the people's clothes to cover it, try to hide it for as long as you can, so as to prepare for future success.

At the foot of the mountain, Xun Yu walked around, and after determining that this nameless hill was the location of the secret road exit mentioned by the Qian brothers, he called Xu Yu over and asked Xu Yu to send some people to guard the surroundings.

Xu Yu nodded, agreed, and went down to arrange Xun You's explanation. After Xu Yan left, Xun Yu walked around and took a closer look, and found that this location was very remote, and few people usually passed by here. Even if you pass by here, you won't pay too much attention to here.

Actually, if you think about it, you know. Since the Qian family put the exit here, they will definitely choose an inaccessible place to avoid being discovered as much as possible. If it was a crowded place, the Qian family would not have chosen this place in the first place. However, Xun You, who has always been cautious, although he believed in this truth, finally put his mind at ease after observing it himself.

After relieving his heart, Xun Yu called Liao Meng, one of the leaders in the team, and asked Liao Meng to take the rest of the people with him.

Xun You took Liao Meng and his party to find the entrance to the secret passage in a valley. Xun You asked Liao Meng to take someone down to see the situation of the secret passage first.

Liao Meng looked at the narrow hole, and in the face of Xun You's order, he jumped down without saying a word. In fact, Xun You chose him because Liao Meng's body is a little smaller than ordinary people, but his body is flexible. Watching Liao Meng jump down, Xun You nodded secretly, and waited anxiously for Liao Meng's situation report for a while. It's really a big deal about this secret passage, otherwise Xun You wouldn't be in such a hurry.

After a while, Liao Meng crawled out of the secret passage. When the men above saw him, they brought him up with a rope. After Liao Meng came up, he stood in front of Xun You, looked at Xun You and said directly: Sir, this secret passage is very small, and it can only be passed by one person inside, and it is still crawling here, and the inside of the secret passage is still tortuous, and there is no possibility for a large army to pass through.

Xun You didn't expect that the situation of the secret passage was not ideal, and looked at Liao Meng and asked directly: Then do you think this secret passage can allow a few people to pass through at most?

Liao Meng thought for a while and said: Eight to ten people will only die in vain.

Hearing Liao Meng's introduction, Xun You stood and pondered, according to his and Huangfu Song's plan, this secret passage must pass through at least a hundred people in order to complete the task in Xingyang City, and now it can only pass through eight to ten people, which is still far from their goal. Xun You was embarrassed where to stand for a while. He didn't know what to do anymore. Now two days have passed, and at this time, Huangfu Song has already set off with the army for a day, and according to the speed of the army, there are only two to three days left for him.

In two to three days, expanding a secret passage that could only be passed by a few people to the extent that it could accommodate more than a hundred people was an almost impossible task.

Xun You looked up at the soldiers standing beside him, and directly ordered that all the personnel, in two batches, take turns to open up the secret passage, and after speaking, let Liao Meng take the lead to start developing the secret passage first.

In the next two days, Xun You and his party have been taking turns to rest, always ensuring that someone digs and expands the tunnel. It's a pity that after two days, the excavation of the secret passage is only half carried out, and the excavation of the secret passage is close to the city, and the excavation has increased greatly.

Xun You's worries are about to have gray hair, and in the past two days, Emperor Fu Song has been sent from time to time to inquire about the progress of the excavation of the secret passage. Xun You also knew that Huangfu Song was in a hurry, but now that he was here, he had already thought of all the ways he could think of. It was already the fastest digging speed he could think of.

Xun You held the latest letter from Huangfu Song in his hand. Xun You didn't even have to think about it to know what was inside. Xun You did not open the letter, but came to the entrance of the secret passage, looked at Liao Meng who was resting on the secret passage, and stepped forward to ask: How is the secret passage excavated, and how long is it estimated to be?

Liao Meng, who had just been replaced, saw that it was Xun You who was asking, dragged his very tired body and struggled to stand up, looked at Xun You and said: Sir, according to the current progress, it will take at least two days.

When Xun You heard this, he was very disappointed, although he had known this answer for a long time, he still expected some good news to appear, and now it seemed that he was thinking too much.

Xun You looked at the tired Liao Meng and said, I'll go down and see the situation.

After speaking, he let the guards behind him support him, and Xun You jumped down towards the secret passage.

Xun You stood in the secret passage, looking at the fresh chisel marks on the secret passage, and could also feel the hard work of the soldiers. Xun You followed the secret road, all the way over, you can see that the secret road is getting narrower and narrower, at the front, the soldiers who are working, only where to climb to dig the soil, which is also the main reason for low efficiency, where the soldiers climb, the strength of the whole body can not be used, can only rely on the strength of the arms to dig the secret road, people are easily tired, even if everyone takes turns to dry, it is very easy to get tired.

After Xun You looked at it, he turned around and walked towards the ground. At this time, Xun You already had a specific idea in his heart.

Standing on the ground, Xun You asked people to call Xu Zhen, looked at Xu Zhen, and directly ordered: From the soldiers brought, select the ones with the most strength, dig in front, and the other soldiers follow him, and everyone moves forward like a sharp cone. In addition, the width of the secret passage has been reduced by half.

In the end, Xun You looked at Xu Yu and ordered: In one day, the secret passage must be expanded to the specified width, which can ensure the safe passage of a team of 100 people.

In the face of Xun Yu's order, Xu Yang had no objections, and went down directly to make arrangements, and Xu Yang also planned to be the first to go on in a while and open the way in front.

Watching Xu Yu go down to arrange, Xun You took out the letter sent to him by Huang Fu Song, opened it and read it, the content of the letter, as Xun You expected, Huang Fu Song asked him about the recent excavation progress of the secret passage in the letter.

From the words of this letter, Xun You could feel Huangfu Song's anxious mood.

After thinking about it, Xun You returned to his camp account and wrote a reply letter to Huangfu Song, in which Xun You made it clear that after a day, the secret passage would be excavated, and the plan could be installed and executed.

After writing it, Xun You called a soldier and asked him to send this long-awaited letter from Huangfu Song.
