In fact, before the start of the operation, Chen Shen did not fail to take this situation into account.

Because he knew that with the support of the Burmese army, the enemy's familiarity with the terrain would be far greater than his own.

But even so, the strategy he expected was nothing more than that the enemy would take advantage of the "route" to seize the opportunity to maneuver quickly, and then arrive at the final withdrawal point before his own side.

Or, further, the enemy could take advantage of the favorable terrain in the jungle to launch undulating attacks on your side, dragging the battle into an "entangled" rhythm, following the trail to take out your own pursuit team and solve all problems once and for all.

But the only thing he didn't expect was that the enemy would actually burrow.

This is not because he is ill-conceived, but because in his view, it is simply a policy where the risks outweigh the benefits.

Even if you know where there is a cave, how can you be sure that the cave is not a dead end?

Even if it's not a dead end, how can you be sure that you'll be able to cross the cave without a guide?

No commander would be stupid enough to make such a mistake, because under these two conditions, drilling a hole is actually equivalent to a high probability of suicide.

Theoretically speaking, as long as you stay at the entrance of the cave and stalemate with the opponent, there is a very high probability that you can turn passive into active and block them in the hole.

——

However, all these risks of drilling holes are only based on the situation of equal strength.

Now, knowing that the Dongfeng Legion has a powerful pursuit group, the commander of the Shadow Corps has realized that there is no way for him to escape in the jungle.

So, he did not hesitate to activate the backup plan, with the most decisive and devastating strategy, to fight for that glimmer of life.

I have to say that this person is really quite a strong opponent.

His judgment of the battlefield situation, his grasp of the fighter plane, and his ability to break through the disadvantage have all reached the extremely "rare" standard.

This made Chen Shen very uncomfortable, he had tried his best to mobilize all the resources and use the local advantage to reduce the space for the opponent to move as much as possible, but in the end, the other party actually took out a "flawless" tunnel battle, blocking all the means he had prepared.

In a sense, Chen Shen simply felt that he was playing with himself.

Because if you think about it from another perspective, the strategy he has to adopt is almost exactly the same as that of his opponent.

Looking at the people who were guarding by the sinkhole, Chen Shen took a deep breath and asked the white dog:

"You have been around Jingdong a lot before, do you have any impression of this cave?"

Hearing Chen Shen's words, the white dog shook his head and replied:

"I don't have an impression, our main scope of activities is still on Meng Yang's side, Jingdong is just a temporary station, and it is impossible to know everything about the surrounding terrain."

"But one thing I can guarantee is that this cave is definitely not so extensive, because the karst caves that extend in all directions are generally built on the basis of a large mountain."

"As you know, it's very close to the Mekong River, and the underground water system is very rich."

"This will lead to an increase in the number of caves, but at the same time, it will also reduce the 'livable' space in the caves."

"We have drilled a lot of holes in Mengyang before, and generally speaking, the closer you are to the water's edge, the smaller the depth of the cave."

"It is likely that after entering from the entrance of the cave, there is at most a not very long tunnel, plus a few small cave halls, and if you want to continue to go deeper, you must use professional diving equipment."

"It's impossible for those people in the Shadow Corps to have professional diving equipment, and it's definitely impossible for them to evacuate along the tunnel."

"Personally, I don't think that drilling a hole does not mean that they have a way to go, but simply because they are completely at the end of their rope."

"At times like these, we should try all possible means as soon as possible."

"Whether it's a fire attack, a smoke, or a direct assault, you have to give it a try."

"We're running out of time, they're definitely calling for reinforcements, and the longer we drag on here, the more dangerous our situation becomes."

"On the contrary, a quick solution is the most likely means of success."

Hearing the white dog's words, Chen Shen nodded approvingly.

In fact, the White Dog's thinking is exactly the same as his, and both of them think that they should launch a surprise attack as soon as possible, but the question is, what method to use?

Chen Shen asked his own question, and everyone, including the white dog, was on alert while discussing it on the radio.

"Fire attack is unlikely, judging from the entrance of the cave, this hole has an upward trend at the entrance, and we simply can't throw fuel into the tunnel."

"It's not impossible, but people have to go in"

"If people want to go in, what are they going to attack? Just hit it in. ”

"What about the pump spraying gasoline?"

"Don't talk nonsense, this time the situation is different from the last time, the terrain conditions are limited, most of the liquid fuel will flow back to the hole, not to mention our own danger, the effect is greatly reduced."

"The really effective way is either to bombard with a large number of cloudburst bombs, or we can get in ourselves."

"Hit a hammer, we don't have a heavy explosion-proof shield, it's better to go in to deliver food, or poison gas."

"Gas? Where did you find so much poison gas? If you say poisonous gas, it's better to smoke directly."

Hearing this, Chen Shen actually had a judgment in his heart.

Yes, relatively speaking, the only reliable methods at the moment are two methods: smoking and direct attack.

The latter is difficult, because the enemy wears anti-infrared equipment, they can only use low-light night vision devices, and the night vision effect is greatly reduced, whether it is in a narrow tunnel or in a spacious cave hall, it is completely unadvantageous.

——

In fact, this point has been verified by Lao Mei during the Vietnam War.

They specially formed a gopher army to fight the tunnel warfare of the Viet G, but this well-equipped unit was still at a great disadvantage when fighting the well-organized Viet G.

According to relevant reports, since the first combat mission in June 1966, the casualties of the Gopher Army exceeded 100 within three months, while the casualties caused by them did not exceed 20 on the Vietnamese side.

The most they did was install the C4 and destroy the tunnels.

And even if they did this goal, they did not accomplish it very well, because in the following year, the Vietnamese tunnel system represented by the famous Gu Chi Tunnel was still expanding, and the total scale was even double that before the establishment of the Gopher Army.

Therefore, Chen Shen does not plan to step on the thunder that Lao Mei has stepped on again, he is almost sure that he will use the "smoke irrigation method" to solve the problem.

Then, there are only two unanswered questions:

First, where to find so many smoke materials?

Second, where do you find a pump that large enough to pump smoke into the tunnel?

Looking at the crowd who were still discussing enthusiastically, Chen Shen once again put forward his own opinion.

However, his two problems were immediately solved.

And the one who answered him was the one who was extremely good at things related to "holes", the rat.

He replied:

"Actually, we don't have to think about it so complicated."

"You're overestimating the extent of the underground cavern - but isn't it just a big rat hole?"

"I don't know if you've ever shot voles, but the size of the vole hole is also very large."

"There are tunnels, there are several rooms, there are huge storage rooms that can hold more than a dozen catties or even dozens of catties of grain, and there are many different entrances and exits."

"If you really want to calculate, the total space can reach the level of cubic meters."

"However, all it takes is a string of firecrackers to smoke the voles inside."

"A small string, the length of a palm, is enough."

Chen Shen was dumbfounded.

He was stunned for a few seconds before he asked:

"You mean, we throw firecrackers into it?"

"Can't you? I really can't think of any better smoke material we'll be able to get anytime soon. ”

"Firecrackers, fireworks, how nice is this."

"It has its own oxidizing agent, which can be burned in an oxygen-free environment, and there is not only smoke, but also a large number of scattered debris particles."

"Well, if we blow up the hole and plug it up, we should be able to suffocate them, right?"

“.”

Chen Shen was speechless.

He knew that the rat plan was not good, and it might not work.

However, it's really worth a try.

Because the cost of trial and error is too low, and the difficulty of implementation is too low.

So, he decisively ordered:

"Contact He Bangxiong and Cheng Lei, and ask them to pull some gunpowder from the Mengbin Fireworks Factory."

"That's right, don't do any fireworks, just give me black powder!"

"The more impure, the better! The bigger the smoke, the better! ”

"That's right, sprinkle some water, soak it. We just burn, don't explode! ”

At the same time, deep in the cave.

Connor was leaning on the ground and gasping for air, his chest heaving rapidly, but not much oxygen was actually absorbed by his lungs, which put him in a state of chronic suffocation, and he felt extremely dizzy and powerless.

Morphine had already been shot, but it didn't improve much for him, and he knew very well that his open pneumothorax injury wouldn't last long, and he had to find a way to escape and operate as soon as possible.

But the problem is that he really doesn't have any way to think about it now.

Because he knew that if he continued to escape in the jungle, the terrible "jungle hunter" of the Dongfeng Corps would bite him like a humanoid hound, and then be eaten by his team little by little with the cover of a helicopter.

This is a huge mistake I have made, that is, to underestimate the abilities of the people who grew up in this jungle.

I've heard of some rainforest hunters in Brazil who can chase anyone they want in the rainforest, and even the Brazilian BOPE has to ask them to give lectures and trains.

At that time, although I did not question it, I always believed that this kind of person was definitely a "very small" group of people who had long been in a bad environment, just like the Sherpas on Mount Everest, and it was impossible for them to appear widely in the world.

But as it turned out, I was wrong.

As long as there is a jungle, there will be such people!

Because this kind of person lives on the jungle!

It's a lesson, a lesson that almost cost me my life.

But fortunately, his adequate preparation finally saved his life.

Although the scale of the cave where the team is located is not large, the tunnel is complex and narrow, easy to defend and difficult to attack, and no matter what method the enemy uses, it is impossible to attack it in a short time.

What you have to do is to make a little repair in the vast cave hall, and after the reconnaissance team from the front finds out the way out of the cave, they can call for support at the new cave entrance, and then evacuate with everyone.

No matter what kind of genius you are, it is impossible to find a flaw in this plan.

Fire attack is not possible, and the terrain will cause the flames to not be able to extend to the interior at all.

Poison gas is not good, because they will not be able to find so many smoke generating equipment and smoke materials in the short term.

Storm? That's even more of a joke.

All I needed was two hours, and after two hours, it was all over.

Connor's body was getting weaker, and the surviving medic in the team had cut open his clothes, torn off the sealing membrane, and used a scalpel to dig out several pieces of shrapnel.

But there was nothing he could do about the shrapnel that remained in his lungs at the depths.

But fortunately, the number of shrapnel that cannot be removed is not too much.

——

Thanks to that tree!

Connor prayed silently, then asked with difficulty:

"How's the situation with the reconnaissance team? Can you find the passage? ”

The medic did not raise his head, wiped the blood with gauze, and then put a sealing film on Connor again, and then replied:

"I don't know, the radio signal is very poor, and we won't know until they come back."

"Don't worry, the air here is circulating, so there must be an outlet."

"Wait quietly, your condition is not as bad as you think, open pneumothorax, no flap formed, hold on, you can't die so quickly."

Connor took a deep and tentative breath, the pain so sharp that he almost coughed, but in the end, he held back.

The medic gave him a shot of morphine, and Connor didn't refuse, but just as he felt that his spirits had improved, a dull explosion suddenly sounded outside the cave.

The general team members clenched their guns vigilantly, and Connor struggled to his feet.

But after that explosion, there was no other movement at the entrance of the cave.

The machine gunners stationed in the tunnel did not react, and there was no new movement from the mines they had set up.

It seems that this is just a temptation.

And their own enemies should have retreated after the temptation.

Connor lay down again, vaguely feeling that he finally had hope of living.

From the time I entered the cave to now, an hour has passed.

In a few minutes at most, the pathfinders will return and escape with themselves.

However, he did not wait for the pathfinders to return, but suddenly he smelled a pungent smell of gunpowder.

What kind of inferior gunpowder did they use in the Dongfeng Corps?

Connor coughed lightly, and then the next second, a scene that made him shudder appeared before his eyes.

——

Under the illumination of the camping lamp, a ghostly white mist drifted into the cave hall.

The scale of that white mist was so large, and the density was so thick, that it almost felt like it had substance.

And just a few seconds later, under the disturbance of the chaotic airflow in the cave hall, the white mist instantly dispersed, turning into pale blue blue smoke.

The feeling of suffocation instantly became intense, and Connor coughed violently.

At this moment, he fully understood.

He knew what his enemies had done, and he knew it at the same time.

I really can't live.
