Centered on the vents, weeds grew everywhere, and the grass was like sugar cane, but it was soft. Falling on it is not much different from falling on a soft cushion. There are obvious signs of being weighed down by heavy objects at the landing position.

"Team leader, those boys are really fateful!" Xue Meng sighed.

If it's hard ground, even if you don't die, you have to put on a little arm or leg or something.

The traces left by Li Mu and them were too obvious, and Xue Meng immediately found their footprints, and was about to chase them, but was stopped by Chen Tao waving his hand.

"Let's take a look at what's going on around you. Chen Tao said in a deep voice, "Let people light torches and walk slowly inside." ”

He was worried that there would be a miasma.

In the worst case, Li Mu and the others went inside and fell to the ground after being poisoned. Therefore, Chen Tao must consider the safety of his subordinates.

The torches were quickly lit up, and the surroundings were immediately lit. What surprised Chen Tao was that so much light failed to hit the wall, which shows how big this space is.

In fact, the transmission of sound can tell how big the space is.

Although he had seen the world, Chen Tao was still shocked by the huge underground fortifications. Don't forget that these permanent field fortifications are not the same thing as permanent fortifications, the former is usually smaller, and fortifications such as the Maginot Line have long been swept into the dustbin of history.

In this way, you can form a concept in your mind, the number of artillery pieces equipped with an artillery division in those years was usually about 300, and even if only one regiment was stationed with the division headquarters, then there were about 100 guns. To hold an underground fortification of a hundred guns, apparently the size of three or two football fields would do. Moreover, artillery cannot be placed in a queue like the exhibition, but each artillery must have its own exit and firing position, as well as a spare firing position!

Chen Tao also started as a small soldier, and in those years they dug semi-buried bunkers for artillery units for the artillery units, and one squad of people worked for two days!

Thinking of this, Chen Tao suddenly thought of K1 Mountain. When he conducted a site survey of the K1 area, he noticed that K1 Hill was very different from other hills. The top of the mountain is a convex place formed by the extrusion of the earth's surface movement, and the formation is regular, and each place reflects the traces of force.

But K1 Mountain is different, it looks like it flew out of thin air and didn't know where it came from, to put it simply, it looks like it was piled up. Over the years, the hill is overgrown with trees and vegetation, and gradually blends in with its surroundings. If you don't look closely, you won't be able to spot the difference.

Now, Chen Tao has reason to suspect that the top of K1 Hill was formed by the accumulation of earthwork excavated from this underground fortification. In other words, it is entirely possible to judge the volume of underground fortifications based on the volume of K1 hill.

Chen Tao ordered the troops to advance cautiously, following the trails left by the 101st squad. At the same time, I hope that Tang Tao's speed can be faster and open up the south exit. So far, the southern exit from the edge of the K1 area is the only known exit. After all, this underground fortification has been abandoned for many years, and the drawings have long been in the war storehouse.

said that Chen Tao was actually not very far from the 101 team, but the twists and turns of the passage made it difficult for both sides to perceive each other.

The further Li Mu and the others went, the more surprised they became, and the front seemed to be an endless passage, full of darkness. At this moment, the two matches on Li Mu's body played a great role, and they made torches, so that they could light up the front forward.

I had been chased by my ass and didn't have time to stop to cook a meal, but the leftover matches came in handy here. As the saying goes, if you lose your horse, you don't know if it's a blessing.

"Squad leader, this place is too big, it shouldn't be the mausoleum of some kind of royal relatives, right? It's gloomy, woo woo woo!" Shi Lei said with his teeth chattering.

People who don't know Shi Lei will definitely think that he is scared, in fact, this just shows that Shi Lei's state is very normal, he is used to expressing his temperament in an exaggerated and ridiculous tone, which is very chic.

Without waiting for Li Mu to speak, Zhao Yiyun brought the torch close to the wall and said, "See clearly, 1969." Your emperor has a ninety-six-nine year. ”

Li Mu added in a deep voice, "Looking at this scale, it must be the underground fortifications of the tank unit or heavy artillery unit back then." ”

Du Xiaofan said, "I'm afraid the exit is difficult to find, and even if I find it, it is estimated that it will be closed a long time ago." ”

"Find it first. Look at this wall, there is no place to start, there is no way to climb up at all, you can only go out through the exit. Li Mu said.

After observing the hole they had fallen into, they also judged that the hole was a vent or something, that vertical height, unless it turned into a gecko.

Then they took out the torches and tried to walk a little further, but they found that it was so large. Surprised, the sharp-eyed Li Mu made a judgment from the passage wide enough to pass through the military cards side by side -- either the underground fortifications of the tank troops or the underground fortifications of the artillery units.

Only those steel behemoths on land need such wide passages.

Li Mu was not very sure in his heart, since this underground fortification was so hidden and did not seem to have been discovered for such a long time, then one thing was completely certain - the troops who used it back then received an order to block this place!

In other words, Li Mu was ready to return the same way in his heart, at least there was still a glimmer of hope when he returned to the cave just now.

He was silently calculating the body in his heart.

The key at the moment lies in the body, you must know that the entire 101 squad has been exercising almost continuously for three days and three nights, and has only eaten one meal of snake meat in the process. Everyone's body consumption has reached the limit, and the body is overdrawn.

Don't forget, there is also a Lin Yu who weighs 170 pounds and needs everyone to share!

"Lao Li, it's a fork in the road again. Zhao Yiyun, who was walking in the front, stopped and said.

Li Mu motioned for Shi Lei to take over from him and Du Xiaofan to help Lin Yu, walked over and took the torch to observe the fork. The passage that can be used by two cars in parallel is divided into two bicycle passages, and there are vaguely visible arrows on the wall, indicating that they are in the right direction, but whether it is left or right needs to be chosen.

There have been two forks in the front, and Li Mu has chosen to the right.

"Left, or right?" asked Zhao Yiyun.

According to Li Mu's character, Zhao Yiyun felt that he would still choose to the right. Li Mu has a particularly distinctive characteristic, he likes to try three times, and if he doesn't succeed, he will become a benevolent.

Sure enough, Li Mu said, "To the right." The last time, when you encounter a fork in the road, you will return the same way you came. I'm afraid, we're going to have to ask for help, we can't die here in a nest. ”

"Okay!"

Zhao Yiyun didn't say a word, and continued to open the road in front of him.

Note: Brothers and sisters of the gun regiment, today is Chinese New Year's Eve, happy Chinese New Year's Eve! New Year's New Year hahaha! I wish you all family happiness and all your wishes!
