"Road? What way? "Hearing Deng Laosi's words, I thought that between the rocks of the landslide, there was miraculously still a passage, but after a closer look, I found nothing.

"Not looking here." Deng Laosi shook his head and stretched out his hand to point up.

I raised my head and raised the fire.

The firelight illuminated the dark corners.

Wow, what is it?

I saw a long crack in the rock wall above, and the entire wall bulged outward, giving people the feeling that something was about to break free at any time.

"If I found out about this earlier, I don't need the third child to go back and get the guy." Deng Lao Sidao.

"What do you mean?" I asked.

"You don't understand that?" Deng Laosi said, "Because the wall here is too thin, it can't stand the pressure during the explosion, and it is smashed through by the stones falling from above - like this, there is no need to thunder at all, as long as our brothers take turns to bombard this crack, the power of the falling rocks inside can open the crack and form a road." ”

"But in this way, won't the stones inside fall, and the road will still be blocked?" I question.

"If it's stuffed with sand, of course it will." Deng Laosi explained, "But listen to you say the situation above, the structure of the hole is very weak, once blasted, it will form a lot of large pieces of gravel - this kind of gravel is too large, most of it can't fall, and it will be erected on top of the bottom row of holes - so as long as the most finely broken sand and gravel at the bottom leaks about the same, the road will naturally appear." ”

"Is that something always falls?" I don't seem to understand.

"Yes, of course, but there shouldn't be too many." Deng Laosi said, "After all, the stone of this Qiushan Mountain belongs to the relatively hard category, the damage caused by the explosion is limited, and the little thing that collapses is not enough to block the tunnel." ”

"Fourth, are you sure?" Lu Zhenyu asked solemnly.

"I can't." Deng Laosi said with a clear eye, "According to my experience, there should be no problem, but if there are any strange changes in the structure of the mountain, such as a pile of sand hidden in the stones, the situation is completely different." ”

"Then what are you talking about?" Fu Lao Wu said dissatisfiedly, "When the third brother comes back, isn't it clean and neat to blow it up directly from the mouth of the tunnel?" You have to think about it. ”

"If there is no narrow road made by the flying eagle, the third child can't get out, then this crack will come in handy." Deng Laosi said, "I estimate that there should be similar cracks in other places, as long as you break it at the same time and open a few more openings, the risk of being blocked by sand will be much reduced." ”

"It's always good to be prepared with a little more preparation." Lu Zhenyu said, "Okay, let's go back and wait for the news of the third child first." ”

So the group returned to the narrow hole and continued to wait.

During this period, Meng Lao Er came with bad news: King Qiujun was not in the palace, and the people in the palace refused to reveal where he was.

The way to ask for help was cut off.

"Second child, this is ...... You go and talk to the general who is leading the troops, and say that there are people inside who can blow up the mouth of the tunnel and let the civilians out, and ask them to cooperate. Lu Zhenyu thought for a moment and commanded.

"It's best to figure out who is dispatching the soldiers guarding outside." I'll interject.

"Yes, find out the situation first, don't make any taboos." Lu Zhenyu nodded.

Everyone understands that when walking in the army, you have to be careful not to touch things like 'military secrets', otherwise you will be worried about your life at any time.

What's worse is ...... You don't even know what's classified until you touch it!

After waiting for two or three more incense sticks, when everyone was anxious, the new news finally came belatedly:

"I figured it out, on the side of Nancheng, the general who led the troops was Duan Zhengqing, the general of Yamen, Hu Yanzhong, the general of the military division in Beicheng, and Zhao Yutu, the general of Huwei, and Li Jiuyao, the general of the Shenxian Army, on the Autumn Mountain, the big men of the Autumn Mountain Army are basically here."

"Where's the prince?" Lu Zhenyu asked.

"Still no news."

"Does the army have any intention of digging tunnels?" Lu Zhenyu asked again.

"Hold still."

"Okay, you try to get in touch with General Duan, remember not to force a request, if he doesn't agree, retreat first and then think about it in the long run." Lu Zhenyu cautiously instructed.

"Yes."

The mink didn't squeak again, and Lu Zhenyu fed it a few peanuts.

The long wait begins......

"Big brother, don't you feel hot?"

"It's so stuffy, it's a little breathless."

"Why is there no wind in this cave? Can it get to the outside? ”

"Alright." Lu Zhenyu said unhappily, "It's not that you don't know, it's better to lie down in this situation and don't talk." ”

There are more and more people in the surrounding crowd who are coughing, lying down, and unconscious.

There was a gloomy fog in the tunnel.

"Second brother hasn't heard from him for so long, will he be ......?" Fu Lao Wu wanted to say and stopped.

"It's time for the third child to come back." Deng Laosi interrupted, "There's no reason for so long?" ”

"Be patient!" Lu Zhenyu straightened his face.

At this time, there was a rustling sound in the narrow hole.

"The third is back?" Deng Laosi said in surprise.

I stared at the entrance of the cave, thinking to myself that maybe it was Xiao Yuanba who came back.

Of course, judging from the current situation, Xiao Yuanba's return can't help anything.

So, who is coming?

"You're all here." Tao Laosan slipped out of the narrow hole.

I sighed.

"Where else can I go if I'm not here?" Deng Laosi didn't have a good airway, "Can you go to the bath?" ”

"Do a good job, get out of this hellish place, let's go to the bath and drink, it's all mine!" Tao Laosan pulled a rope in his hand, pulled out a burlap bag from the hole, and threw it to Deng Laosi.

Deng Laosi opened the sack and saw that there were bundles of iron rods in it.

These are the 'thunderbolts' of Deng Laosi's unique deployment, also known as the 'fire stick', which is four or five percent stronger than what can be bought on the market, and with exquisite setting techniques, the explosion effect is not trivial.

"That's right, Fourth Brother Deng." Seeing these thunderstorms, I suddenly felt in my heart: "If you are asked to go to the mouth of the tunnel before the blasting, will these thunderstorms be enough?" ”

"You mean blow up the tunnel mouth?" Deng Laosi pondered for a moment, "It may not be enough - the weight here is more than enough to blast the gravel blocking the tunnel entrance, but the intact tunnel mouth needs to be drilled in a specific position and detonated from the depths of the stone layer, and the weight is less, even if it can be blown up, it will not collapse as much as it is now." ”

"Could it be a powerful firearm capable of blowing up the mouth of a tunnel with a single blow?" I asked.

"How is that possible?" Deng Laosi shook his head and said, "Nowadays, people have heard a lot of storytelling, and they always think that if they just throw a small ball, they can blow up a room everywhere - this kind of powerful firearm, Lei Huotang can't make it." ”

"If so...... What kind of person is that, who has the ability to detonate the mouth of the tunnel under the noses of many soldiers and civilians? ”
