Xi Jing'an felt it was all very surreal; they had been captured by bandits and taken to their stronghold, only to be released by the same bandits.

Turning to look at the now-closed mountain wall, Xi Jing'an said in disbelief, "Sir, are we just leaving like this?"

Xu Di laughed and said, "What else do you want to do if we don't go this way? They were forced into this situation because they had no other choice. Otherwise, we wouldn't be able to get into their base even if we wanted to. But I reckon if I bring people back, we definitely won't find the mechanism to open this stone door."

Xi Jing'an asked curiously, "Why? I was standing behind Brother Gong and I saw it clearly. He put his hand on that protruding stone and twisted it, and the stone door opened."

Xu Di patiently explained, "There was a master of mechanisms in the previous dynasty who made exquisite mechanisms. I heard that he disappeared in his later years. I think he was probably imprisoned in this valley and used all his knowledge to make so many mechanisms in this valley, which is a natural hiding place. Since he dared to operate the mechanisms in front of us, he was not afraid of us seeing it."

Xi Jing'an exclaimed in admiration, "If we place these mechanisms along the border river, will we still have to worry about the Great Yan attacking?"

Xu Di shook his head and said, "This is different. That valley itself is a natural hiding place. With the addition of traps, it is not easy to find. If someone had been regularly sending them daily necessities from the outside, they probably wouldn't have thought about coming out. But now, the supply of the resources they relied on for survival has been cut off. When you're desperate, you have to think of other options, so they had the idea of ​​coming out. But it's easy to get in, but difficult to get out."

Thinking of those people's lives, Xi Jing'an sighed and said, "Their lives are indeed too difficult. They don't even have food. Those chairs and tables look like they haven't been replaced for many years. Sir, do you have a way to bring them out of the valley?"

Xu Di shook his head and said, "There are too many of them. It's not something I can decide alone. It depends on what His Majesty thinks. I've already sent someone to deliver a message to His Majesty. I estimate that His Majesty will issue an edict soon. After all, they are all relatives of the former dynasty. Even if they want to stay in Daliang and live a good life, they first need to have a legitimate identity in Daliang."

Xi Jing'an voiced his confusion: "Sir, how can they lock themselves in this valley? It's such a small place, yet they have to house so many people. It's not as comfortable as living outside."

Xu Di thought of his guess and said, "There must be a reason why they let these people live here. I think they were able to settle down here because of that elder of the Zhu family. They needed a safe place to grow up, and they also needed to leave them enough money to do some things. This place is so hidden, it must be where the treasure of the previous dynasty was hidden. But in the end, the people grew up and left, and the treasure was used up. These people were actually abandoned."

Xi Jing'an said with great sympathy, "They are really pitiful."

Xu Di, however, thought differently. He said to Xi Jing'an, "In chaotic times, having such a secluded place where they can live peacefully, and most importantly, have enough to eat and wear, is something many people wouldn't even dare to dream of. They are very lucky to have survived like this. But now, while the outside world is peaceful and prosperous, they are facing a shortage of supplies to survive because there are more and more people inside. If they want to continue living, they can only come out of there. Your master, I have now become their lifeline, but I don't know if I am the only one."

Before they even reached Wuzhou, Ma Ming and his group came to greet them. Xu Di didn't want more people to know what had happened in the valley, so he didn't tell Ma Ming the truth, only saying that his group had spent the night on the mountain.

Ma Ming is very anxious. Wuzhou is dragging on like this, and it really can't be delayed any longer. Right now, the morale of the Great Yan is low. If we press on, we can easily drive out the Great Yan people who have invaded the territory of the Great Liang and then recover the land that the Great Liang has lost for more than two years.

Xu Di stood on the city wall, gazing at the distant camp of the Great Yan. From Wuzhou to the border river, because these places were not very safe, there were no villages in this area of ​​less than twenty miles. There were originally a few villages, but they were moved to the east side of Wuzhou City. Therefore, the Great Yan had to transport its grain and fodder from the other side of the river.

Xu Di asked Ma Ming, "How often does Great Yan transport grain from the other side of the river?"

With tens of thousands of people, the daily food and fodder required was quite substantial. Also, fearing a surprise attack from the Great Liang, the Great Yan people did not have a large food reserve and had to frequently transport food from the other side of the river to this side.

Ma Ming said, "The scouts said they deliver it once every five days."

Xu Di nodded and said, "Find a few special forces soldiers to sneak over from the upper reaches of the border river, bring kerosene, and burn their supplies. Burn them every time they come. Do you think they won't voluntarily withdraw?"

Ma Ming asked with some doubt, "Will this work?"

Xu Di shook his head and said, "Of course that won't work. We still need to put in some effort here. You go and pick out people first, find those who are good swimmers, and I'll train them first."

Ma Ming happily agreed and went to the camp to select people, while Xu Di took out his binoculars and quietly observed the camp in the distance.

After An Muyuan was captured, the reason why the Great Yan was able to continue to hold Wuzhou was because the commander here was a famous general of the Great Yan. Last time, he almost knocked down the city wall of Wuzhou. If it weren't for the cement, if it happened again, Wuzhou might have changed hands and become the territory of the Great Yan.
