When everyone arrived, Nangong Jin was bowing his head and drawing something on the picture that Feng Yue had brought. After a while, he looked at the picture in his hand and muttered: "I just said how can it be so familiar, no wonder ......, Zhao Yingfeng!" ”

"Boss!" Lu Ao couldn't help it.

Nangong Jin raised his head, as if he hadn't come back to his senses yet, and looked at them and said, "Heaven and Earth Great Array!" I never thought he could form a formation. ”

"What?" Lu Ao asked, "Are those monsters outside the city?" ”

Nangong Jin nodded, "The Heaven and Earth Qiankun Array is a defensive formation, and it never takes the initiative to attack. So, those medicine men are always standing there. ”

"There are about a hundred monsters on the east and south sides, if you want me to say that there are ten times as many people as them, we Tianchengwei can still afford to go out, and we are afraid of these hundred monsters?" Lu Ao said loudly.

Nangong Jin shook his head, "The Qiankun Array is changeable, and when you step into the formation, what you see in your eyes is not more than a hundred people." Everyone who enters the formation has the potential to become a part of the formation, and will become a helping hand for those who kill themselves. Unless, everyone can not dissolve into the ...... formation. ”

Jin Jianchang's eyes lit up, "Can the coach break the formation?" ”

Nangong Jin lowered her head and pondered, and became anxious again for a while. Feng Yue interrupted: "Boss, it's better to talk about the people first." ”

Nangong Jin nodded, put down the picture in his hand and said, "Everyone, I heard that there is a coal digging tunnel under Tianchengwei?" ”

There was a moment of silence, and Nangong Jin almost thought that she had said something that she shouldn't have said. Jin Jianchang and Lu Ao were excited; Ding Xionghui may be a little younger, and he has never heard of this kind of thing, and his expression is a little dazed; It's just that Zhang Maocai was a little excited at first, but after thinking about it, he still shook his head.

"General Zhang?" Nangong Jin noticed.

Zhang Maocai smiled bitterly, "Boss, there should be a tunnel, but the poisonous gas is permeated." Besides, it's been a lot of years, and I don't know if it still leads to the outside of the city. ”

"General Zhang knows where?" Nangong Jin asked.

Zhang Maocai thought about it and shook his head, "The coach can ask Lin Fei, he is a local." ”

"Oh yes." Jin Jianchang laughed, "I was just wondering who told me about drilling holes when he was a child. Boss, Lin Fei should know. ”

In less than half a burnt of incense, Lin Fei was called up, and he had now changed into a soldier's attire. Seeing Nangong Jin, he knelt down directly, "Lord, boss." ”

Nangong Jin is still the same, "There is a pit under Tianchengwei?" ”

Lin Fei was stunned, and for some reason, he suddenly remembered the scene when Nangong Jin announced that he would behead Chen Baishui, and now Chen Baishui's head is still hanging in the city. Suddenly started to tremble, shaking his head desperately, "I don't know, the last general, no, no, the little one doesn't know ......"

Jin Jianchang got up and patted Lin Fei, "Don't be afraid, it's okay." I remember you said before that when you were a child, you drilled everywhere and found that there were several pits under Tianchengwei, didn't you? ”

"This, this ......." Lin Fei didn't know what they meant at all, let alone whether he should answer or not.

Nangong Jin said: "We are trying to find a way to break through. Come on, it's okay to say something wrong, it's just a reference. ”

"Yes, yes, there is ....... However," Lin Fei said in embarrassment: "However, some of the poisonous gases and some may be blocked, they were all a long time ago, but there is a bigger one, but it is not a tunnel, it is a karst cave, it is very big, and it will definitely not be able to go outside." ”

Nangong Jin straightened up, "General Ding." ”

"Yes."

"You take Lin Fei to Mr. Gao. Previously, Mr. Gao also talked about the tunnel. You're in charge of finding out the tunnels and finding out what's going on. ”

"Yes."

"Also, stay safe, and come back to defend the city."

Ding Xionghui looked at Nangong Jin, smiled, and said loudly: "The last general will take the order." ”

Nangong Jin looked down at the picture in his hand again, and said to everyone: "General Jin, General Zhang, and General Lu, leave fifty soldiers at each gate, and the rest will all gather in the school field after two quarters of an hour." Starting today, all the soldiers will be practicing in battle. ”

"Training?" Zhang Maocai asked rhetorically, got up instantly, and said directly to Nangong Jin: "The last general will take the order." ”

Jin Jianchang looked surprised, also got up, and said loudly with Lu Ao: "The last general will take the order." ”

Nangong Jin looked at Zhang Maocai and explained: "At this time, in fact, I don't want to toss everyone. However, the formation outside the city, although he has not yet figured out how to break it, it is certain that the soldiers must understand the formation, and all parties must cooperate to have a chance of winning. Whatever the solution, you have to give it a try, right? ”

"The last will understand." After saying that, the three of them retreated.

Feng Yue waited for Nangong Jin to give an order, Nangong Jin looked at him, and finally said after a while: "Is there a way to get some more food?" Even if it's a full mix. ”

"The camp now has two meals a day, brown rice porridge with some vegetable leaves and roots. Kill everything you can, including military horses. Feng Yue replied.

Nangong Jin sighed, "I know." ”

Feng Yue smiled bitterly, "I also want to suggest to the coach that the barracks should be reduced to one meal a day, which should be able to last a little longer." And what I eat now is actually the previous feed. ”

Nangong Jin leaned back in the chair and whispered, "Let's have two meals until tomorrow, and reduce it the day after tomorrow." After a while, I cheered up again, and I didn't know whether to ask or say to myself, "They have been around for so many days, they should have something to eat, right?" ”

"Tartar grabbing?" Feng Yue blurted out.

"You say, how about we go to camp at night?"

Feng Yue looked at Nangong Jin for a long time and didn't speak, "West, north? ”

Nangong Jin nodded, "Two teams are out of the city at the same time, it may be difficult to break through, what if you just grab it and run back?" ”

"We don't know where their food and grass are, so it would be reckless to do that. Even if you grab it, you don't know if those things are worth your life for. Feng Yue didn't disagree, he just felt that it was too hasty.

Nangong Jin felt a little stuffy in her heart, and she didn't know if she was tired or hungry, so she whispered: "It's also a fatal thing to be trapped here." Does Zhao Yingfeng want us to descend? Or did he have some other way of taking all of us alive? If you don't fight today, what do you want to do? ”

"It's not impossible to try, but it's just that several gates are welded ......." Speaking of this, Feng Yue stopped, thought for a while, and said, "There's coal down here." If there is coal, the blast furnace can be used. ”

Nangong Jin also answered, "I've seen someone use coal to make fire oil, just one point." ”

The two looked at each other for a long time, and Feng Yue asked, "Is it possible to ......?" ”

"It should be possible."

"Those pits!" Feng Yue immediately got up, "I'll go find Mr. Gao." ”

Nangong Jin rested and got up to go to the school grounds.

The soldiers at the north gate knew Nangong Jin's rules, and they were consciously divided into groups of ten, shields, knives and guns, each holding a different weapon. This is worry-free, Nangong Jin directly asked the soldiers of the North Gate to practice according to their daily drills, and explained to the four generals the method of cooperation between groups. All of a sudden, the school field was also in full swing.

When Feng Yue arrived at Gao Changjing's place, a group of people were discussing a hand-drawn picture fiercely. There are a few old people who are very old, and they are babbling stories from previous years, as if no one is listening. And Lin Fei and a few people who were about the same age as him were arguing loudly about something, and Gao Changjing and Ding Xionghui were listening very seriously. Fortunately, it didn't take long for them to decide to go and see it live.

Feng Yue pulled Gao Changjing, "Mr. Gao, if there is coal, can you start the blast furnace?" Refining oil? ”

This sentence reminded Gao Changjing, and he hurriedly called a few masters and took them and Feng Yue to see those tunnels.

There are a few entrances that have been buried, saying that they have died a long time ago by overflowing poisonous gas, and after going around the city for a long time, they found that the big karst cave that Lin Fei said could go in, and the tunnel found a person who could leave, but I don't know where it leads, according to Lin Fei's friend, this tunnel should have collapsed long ago, and it may not be able to pass outside the city, after all, the one used to dig coal does not consider coming out from the other end.

Ding Xionghui volunteered to go inside to investigate, lit a lantern, and set off with a cloth rope hundreds of zhang long prepared by Gao Changjing.

The tunnel is not big, it should be possible to walk three people side by side, and the height is also one person high, and the entrance of the cave is protected, but it has already collapsed after a long time, and the tunnel has been extending downward. Ding Xionghui didn't know how long he walked, but he still kept going down, and there seemed to be coal on the walls on both sides, so he took out a knife and dug a piece.

However, the rope seemed to be coming to an end, and Ding Xionghui put down the rope and made a mark and began to count steps. The road in front of me did not continue downward, and after walking forward for a short time, I found that the cave wall had collapsed, and after climbing over this collapsed place, there was still a road in front of me, and there was a tendency to go upward. After walking for a long time, I found that I was at the end, but there seemed to be a faint light of heaven above my head. Ding Xionghui tried his best to lean against the cave wall and look up, but it was still too far from the ground to see where it was.

The people outside waited for a long time and became anxious. When discussing whether to send someone in to take a look, Ding Xionghui came out.

"The pit was very long, and the rope was finished, and there were three thousand two hundred and seventy-two steps, but it could not be reached outside, and it was over. There are small holes dug in both sides along the way, so I guess the coal was dug at that time. Ding Xionghui said as he took out a piece of coal from his arms and handed it to Feng Yue.

Lin Fei's face fell, "In this way, it's ......." ”

"No, no, no." Ding Xionghui said: "The section that is almost to the end should be very close to the ground, and there is light coming in, but it may still be too far from the ground, and I can't see where it is." ”

"Hopeful?" Lin Fei became happy, "So there is hope? ”

Ding Xionghui nodded.

Feng Yue gave the coal to a few craftsmen, only to hear them say: "The quality is average, but there is no problem with opening the blast furnace." Refining oil may not work. ”

Gao Changjing said: "If it is coal mining, more than this tunnel can be used. ”

"However, Mr. Gao and General Feng, there are several serious collapses in this tunnel, and the support is not enough, I am afraid that it will collapse." Ding Xionghui added.

Feng Yue said to Gao Changjing: "Can you open a blast furnace to refine fire oil now?" According to General Ding, this tunnel should have been out of the city, the key is that I don't know where it is on the ground, if you want to dig through the ground, there must be movement. The coach means that he can rush to the camp and cooperate, and attack the east and west. However, we don't have weapons in hand now, and it ...... be too dangerous for the soldiers to rush into the camp. ”

"So, you want kerose." Gao Changjing nodded, "Leave this to us in advance." Tomorrow at the latest, you can refine as much as you can. ”

"Okay, trouble Mr. Gao, be careful." Feng Yue looked at the craftsmen.

The master craftsman smiled: "General Feng, don't worry, we have all done this before." ”

"Thank you." After speaking, he directly took Ding Xionghui and Lin Fei away.
