Several people lit torches and explored the big hole. This long underground cave is actually a limestone karst cave that is very common in the Taihang Mountains. The uplift and fracture of the earth's crust, combined with the erosion and infiltration of limestone by rainwater, caused the emergence and stratification of such caves.

From the perspective of walking Xiangshang, it should extend from an underground dark river in Langya Mountain in the north, which may be caused by an earthquake or something, and this cave has become a hollow.

The big hole that everyone is exploring at the moment is more than 10 meters high and dozens of meters wide, narrow at the top and wide at the bottom into an inverted bowl. The surface of the earth was covered with sand, and it became a mound, and the local people made a grave.

There was also a small hole in the wall of the cave on the south side, which could only allow one person to crawl through, and the shovel monkey shrank in and shone it with a torch, and when he returned to say that the small hole was quite long, and he did not know where it led. Yang Bangzi meant not to go forward, so he discussed how to find the passage to the top.

Not to mention the passage that is really not difficult to find, just when the shovel monkey exited from the small hole, directly above the entrance of the cave, some dust fell down, Yang Bangzi looked in the direction of the soil falling, and vaguely saw the side of the dome of the cave wall, and there seemed to be a crack in the rock wall.

That's where the dirt fell. Yang Bangzi handed the torch to the people around him, held a piece of fire fold in his mouth, picked up the stalactite, and rubbed the ground on the rock wall. The moss on the stone wall is slippery, and there are water droplets rolling down, not so easy to climb, Yang Bangzi has worked as a miner, and has many years of experience in mountain warfare, and finally approached the top of the cave without danger.

The crack can be several meters long from top to bottom, and at its widest point it is about a meter wide. Yang stick pedaled on the stone ridge with his foot, grabbed the stone crack with his right hand, and reached over with his left hand, paddling the sand. I grabbed a handful, held it up in front of my eyes, and twisted it with my fingers, it was quite dry, different from the damp soil in the cave.

The shovel monkey said that the soil was leaking from the soil above, and it was estimated that the crack was through it, and he volunteered to go up and explore it again.

The shovel monkey's ability to climb the rock and walk the wall is more neat than Yang's stick, carrying his flat shovel and a torch, sticking to the rock wall like a gecko, a few clicks to the edge of the crack. He lit the torch with a fire breaker, inserted it into a small stone crevice, tied it to the stone pillar with the silk thread he carried, and hung the whole person on the top of the cave.

Use a flat shovel to dig out the sand in the cracks, large and small stones, and dirt, and fall to the bottom of the cave with a snort. Suddenly, the shovel monkey whispered, "Be careful! The few people below who were tilting their heads hurriedly took a few steps back.

A few things fell in a hurry, and it really scared these people! The rotten coffin board that doesn't come out of the black is nothing, and the white miserable bones, sticks, and skeletons are really scary to look at in the firelight! Yang Bangzi pursed his lips and said, "What a sin, digging out other people's graves!" ”

Yang Bangzi is right, there is indeed a tomb on top of this crack! Originally, it was a long time, and the rain corroded and infiltrated, and some small cracks appeared on the top of the cave under the tomb, and the floating soil was lost with the accumulated water, and the stone cracks under the tomb became bigger and bigger.

Just after the big black snake fought Qingshui Dazuo during the day, he was hit by a machine gun, panicked, and saw a tomb collapsed, revealing the hole, so he drilled down, and when he desperately drilled into the crack of the stone, the devil's grenade threw in, and when it exploded, the snake was injured, and the shock wave of the explosion was also shaking the stone crack wider, and the big snake entered the cave.

The explosion completely collapsed the tomb, and the coffin board blocked the cracks, and the gravel and floating soil on it didn't all pour down, so the devils on the post didn't find the cave below.

The shovel monkey stirred it up, stabbing the coffin board and everything, and the collapsed tomb was empty, and a cool breeze poured down in an instant.

The shovel monkey harvested the shovel into a stick again, pinned it to his waist, shook his body a few times, kicked his feet on the rock wall, and swayed leisurely, grabbed the edge of the crack with both hands, and jumped up with a "whoosh" and jumped into the crack.

Poked his head out and used gestures to tell Yang Stick that he went up to see the situation. Then in a flash, the man was gone.

The shovel monkey went to explore the situation, Yang Stick was not idle, blinked his eyes, walked over, picked up the coffin board and collected the white bones on the ground, gathered them together, piled them on the edge of the rock wall, and used the fallen stones and soil blocks to pile up a grave again.

As soon as he finished doing this, the soil face fluttered and fell again, and as soon as Yang Stick raised his head, the shovel monkey came back, shook along the silk rope a few times, and went down to the ground.

After taking a few breaths, he said that this crack leads straight to the west half of the slope of the mass grave post, and after he went up, the cat saw in the dirt pit that the devils were all on the top of the dirt slope, in a circle, and there were two mobile posts on the north and south sides of the slope.

In addition, he also heard that there were still people whispering in the devil's position on the top of the dirt slope, and it was estimated that there were still devils on duty who had not slept.

The shovel monkey is digging a hole to make an ancient tomb or something, this reconnaissance and inspection of the terrain or something is a layman, Yang Stick asked about the firepower configuration, the depth of defense or something, the shovel monkey couldn't figure out his head when he heard it, and he couldn't say it clearly.

There is no need to complain, Yang tightened his belt, took off everything from the strap on his body, let the big man hold it, pinned a fast and slow machine on his waist, and went up to the rock wall.

Along the route just climbed, after approaching the crack, I didn't use the silk rope left by the shovel monkey, but simply put my hand on the stone crack, and then stuck my body upside down on the stone wall, holding the stone ridge, and moved my hands and feet alternately little by little to the bottom of the crack.

Crawling lightly to the edge of the pit, the waning moon is like a hook, the starlight is dotted, and the scene on the post is quite clear. Yang Stick pulled some weeds and made some camouflage on his body, quietly crept out of the grave, stuck to the head of the grave, and turned the post in a circle.

The situation is basically clear, and the earthen hill surrounded by water is still about a few dozen meters away from the water's edge to the top of the slope. At the top of the dirt slope, the devils built a half-human-high bunker with trees floating in water, and most of the devil soldiers were concentrated inside.

From the top of the slope to the slope at the water's edge, the devil also used the tomb bun to build some temporary buns, Yang Bangzi counted them, and there were about a dozen places where the devil was stationed alone.

In addition, there are three mobile posts on the post, patrolling in circles along the individual bunker and the main position at the top of the slope. There is no way to figure out the situation in the main position, but Yang Bangzi judged that there were at least 100 devils on the gang according to the scale of the construction of the devil's position.

After returning to the cave and telling everyone about the reconnaissance, Yang Bangzi said his thoughts, which means that the original plan of going up to carry out a raid is not suitable, and he has to think of another way.

There are three reasons: First, there is too little room for maneuver on the earthen hill, and the position built by the devils basically accounts for most of the gang. The second is that the crack is too narrow, and only one person can pass through at a time, and after going up, the troops cannot be spread, and it is easy to be discovered by devils. The third is that if the strong attack can't annihilate the devil, retreat, the hole will be discovered by the devil.

Yang Bangzi also said one thing that he was worried about, that is, in another hour, the sky will be bright, and he doesn't want to come up with a plan of action, and when the sky is bright, the devil's patrol post will find this hole!

The big one means that some people will go up first, ambush next to the devil's individual pit, and wait for the battle to attack the devil's slope top position as soon as the battle starts, and immediately destroy the devil's skirmisher position.

Yang Bangzi directly vetoed this suggestion, and said two reasons why it is not feasible, first of all, we have people, and there are no more than ten people with rich combat experience together, and the rest are basically recruits who have not fought a few battles, even if they are one-on-one, can they take the devil's position?

Secondly, even if more than a dozen devils are stared at one-on-one, how can the fighters who mainly attack the top position of the slope deploy? How to get close? How to solve the mobile whistle? What if the devil still has a secret whistle? The sneak attack was found to be changed to a strong attack, what should I do if I can't take the devil's position?

After listening to it, everyone felt that Yang Stick was right, he couldn't eat it in one bite, and sent one or two people to go up and throw a grenade or something, but it also exposed the stone cave where he was hiding, and the gains outweighed the losses.

I don't say anything, I really can't think of any good way, it's like looking at a hedgehog, wanting to eat meat in my mouth, the thorns in the hedgehog's body, I can't go down my mouth!

Time passed minute by minute, and he still didn't come up with any way, and the torch he brought was about to burn out, and the big man became impatient, stood up and said that he would lead a few people up, so that he could make a devil, and after retreating into the cave in chaos, he used a grenade to blow up the crack and seal the hole.

That's right! Yang Bangzi had a flash of inspiration in his mind! "Fried!" Pregnant! It's not about blowing up this crack! Is it okay to blow up the whole hole! He thought of the two vats of gunpowder!

grabbed the wrist of the shovel monkey and pinched it with a grin! Ignoring the protest of the shovel monkey, Yang Bangzi asked eagerly, "Man! Do you think this hole can be blown up? Give Lao Tzu a transparent word! ”

"Let go of my hand first! Captain Yang! The shovel monkey blushed and shook the big black hand of Yang's stick vigorously.

Yang Stick let go of his hand a little embarrassed, the shovel monkey shook the wrist that was clutched red, looked up with his head up, and then said that he went up to take a look, climbed the stone wall with the silk rope, walked around, returned to the ground and said excitedly Almost, he looked, the stone wall on the top of the cave seemed not so thick.

The shovel monkey probed with a flat shovel and found that the stone on the top of the cave was not the kind of particularly strong bluestone slab, but also gray stone, and there were cracks all over the place in some places, which were so loose that when the shovel poked, the stones fell down.

It turned out that this big hole was not formed naturally at the beginning, and it was corroded and peeled off by water for many years, and this dome was gradually formed. The big one went back to get the torch and came back, and the shovel monkey went up again, and found out that the stone walls on the top of many caves were only one meter thick, and then there was the soil layer above.

Now Yang Stick came to the spirit and explained the idea to everyone, that is, to blow up the roof of the cave with gunpowder, so that the top of the soil slope above the roof of the cave will not collapse completely! What kind of sneak attack and forcible attack, the devil's position will fall into this cave and be buried!

The big guy thinks about it, yes! If you can blow up the roof of the cave, the little devil will be buried in his dream! And unknowingly, even if there are devils who survive, they will never imagine that there are eight ways underground that blew them up with gunpowder. After finishing this ticket, I will find an opportunity to jump out of the encirclement and interception of devils on this road.

Even if the entire roof of the cave can't collapse, at least part of it can be blown up, as long as the passage leading to the Xiangshang side can be blown up, the devil will definitely not be able to find the passage for a while, and the team will not lose anything, and it will be too late to find a way to get out.

After discussing it, there were no opinions, and Yang Bangzi began to assign tasks.

The shovel monkey was responsible for digging holes in the top of the cave along the stone wall, and under the dome, there was a circle of open gunpowder holes, and Yang Bangzi specially instructed that two more holes be opened in the cracks. The shovel monkey said that he is the best at opening holes!

The task of the big one is to go back and gather people, use the straw bags in the ear room to transport the gunpowder, and tell everyone not to mess around, and to light and lead the way away from the people who carry the gunpowder, but don't have an accident.

The task of the old five sons is to monitor the movements of the devils in the dirt pit in the crack before the completion of the gunpowder blasting point.

Yang Bangzi also reminded the big man to look at the backpacks of the fighters and find two old quilts, especially emphasizing that they were old quilts! At least the kind that hasn't been dismantled and washed for three or two years!

That's pretty rare! The big man scratched his head, muttered a few words, and went back to order someone to carry gunpowder.

Yang Bangzi sat on the ground, lit a cigarette pouch, took a beautiful puff, and said in his heart: "Little devil, grandpa will set off a big fireworks for you today, so that you rabbit cubs can have a holiday!" ”
