Within the Liaodong Combat Command.

"The current situation is like this. It is very likely that the Goguryeo people will come over quickly, and our defense has only completed a little more than one-third. Based on the current speed, it is estimated that it is difficult for us to defend the Goguryeo people. Go north." Meng Fang said of the current situation very pessimistically.

"It seems that I have to report the situation here and let them handle this matter. This is beyond the scope of what we can handle." Zhao De said, shaking his head. In the face of the current tense military situation, he can only do so. After all, their abilities are very limited.

"I. No comment." Guo Sheng also nodded in agreement. After all, there is only this he can do.

"Well, we will report the situation here to the above, let them know our situation, unless we send reinforcements, or build a wider combat unit to defend, that is to establish a second line of defense behind us, otherwise we There is simply no way to complete such a task." Zhao De said.

When other people heard this, they nodded and agreed. They didn't have any opinions. After all, there are not many facts that can be disputed in such a meeting. Their defense area is too large and the manpower is too few. And the time is short, they are just defense, and can't do anything. In such a situation, what they can do is to make the defense circle as better as possible.

"Yan State's urgent telegram." Yang Duanhe said to Wang Jian anxiously.

"What is so anxious?" Wang Jian asked.

"We have received a reliable investigation report on the Liaodong Defense Line of the Yan Kingdom. The Goguryeo people have already begun a large-scale assembly. I think it won’t be long before they will go north and enter the Liaodong area. In this way, the Liaodong Defense Line of the Yan Kingdom will be Collapse." Yang Duanhe said.

"Aren't we laying a lot of landmines on the Liaodong Defense Line?" Wang Jian asked puzzledly.

"Well, we did deploy a large number of mines, but we cannot deploy mines in all places, and things are happening very urgently, and the time given is not enough. We need at least three mines to complete mines of that scale. It took more than a month to complete, but we only gave them one month to deploy a little more than one-third of our defense. And Goguryeo has already planned to go north. We must think of a way to solve this problem . Otherwise, it will cause a lot of trouble to Yan Guo’s investment. I think the prime minister’s residence means this.” Yang Duanhe said.

"Oh. I understand." Wang Jian nodded.

"The current situation is very unfavorable to us. We don't have a second line of defense, and there is only one line of defense that can be defended, and there are no other lines of defense at all." Wang Jian said embarrassedly.

"The situation of Yan State is that it is impossible to use so many troops to lay out the defense line. And we are not willing to send troops, not only we are not willing, I am afraid that Zhao people are not willing to send troops. If this continues." Yang Duanhe is very Speaking pessimistically.

"Okay. Don't talk about things like this anymore. Although we don't want to, we still have to think about ways." Wang Jian said.

"Yeah." Yang Duanhe nodded in agreement.

"If I were from Goguryeo, I would enter Liaodong from the Changbai Mountain area. After all, the terrain is complicated, which helps them to conceal and approach us." Yang Duanhe analyzed.

"But the intelligence said it was going north, which means that they might gather in the southeast direction. After all, there are a large number of Goguryeos gathered there. Don't forget. It was in this direction that the Yanjun was driven back to Liaodong by the Goguryeos. "Wang Jian analyzed.

"In this case. The line of defense is too big. There is no way to prevent it. And the force is not enough. It's really a problem." Yang Duanhe shook his head, his current line of defense. He had lost his complete interest. In his opinion, the Yanjun Liaodong Defense Line was basically unable to resist the Goguryeo people's northward movement.

"If you want to keep Liaodong, there is probably another way." Wang Jian said while looking at the sand table.

"What way?" Yang Duanhe asked.

"It is to use the current defense to drag the enemy and let the enemy bypass our defense line, and then they can't further attack the next area. If the next area can be resisted, I think, in this way, the matter will be resolved. "Wang Jian said while looking at the sand table.

"The next area, in this case, will enter the vicinity of Xiangping, the Zhishuo of Liaodong. The impact will be too great." Yang Duanhe said while looking at the sand table.

"There is no way for them to prevent the Goguryeo people from attacking. We can only quickly dispatch troops from other places to help them build a second line of defense, otherwise we will not be able to keep Liaodong. We only have to drag the Goguryeo people to death. , And there is no other way, and Yan's military strength is very limited." Wang Jian said without any other way.

"Well, we can only do this." Yang Duanhe nodded and said.

Inside the city of Xiangping, Liaodong, Yan State.

"Teacher, can you really be sure that we are looking for iron ore?" a student asked with a pencil and notebook in his hand.

"Yes, it must be. The teacher's experience has judged that this is definitely an excellent iron mining area." said a middle-aged man sitting on a donkey.

"Oh. But, the iron component I saw is relatively small. Such a big stone. This." The student asked puzzledly.

"Okay. The teacher will explain to you." The middle-aged man on the donkey jumped off the donkey, and then took out a sample of the ore to explain.

"Look, this kind of ore contains iron. But its content is not very high. It may be a kind of mineral that is not rich, but this kind of iron ore has one characteristic. It has a very large quantity and is buried. It’s very shallow, you said that the content is small, but the quantity is large, and the burial is shallow, is it easy to mine?” The teacher explained.

"Oh. I see. That is to say, this kind of mine is convenient to mine, and it is much simpler than the rich mines we found before. It is not easy to mine. And the cost is low." The student said excitedly.

"That's right. When we study minerals, we must learn not only to find ore, but also to learn one thing, how to develop and use this thing, and the knowledge in it is much greater. Moreover, prospecting requires experience. For this kind of mine, you have to keep it in mind and apply it flexibly, do you know?" the teacher taught.

"Student understands." The student quickly recorded as he said.
