They were all specially trained soldiers, and the marching speed was very fast, and at nine o'clock in the evening, Li Yunlong and his party had already come to the outer area of the coal mine discovered by the Japanese Kingdom.

Feng Siyang pointed to the area where the lights were on, "Instructor, that's where we went last time, but as soon as I got close to that fence wall, I was discovered." ”

"Yes, instructor, fortunately, Commander Feng found out in time, if it was a little later, we would have been suddenly knocked out by the opponent's machine gun."

"You mean, there is a machine gun point around this fence wall?"

Feng Siyang nodded, "Yes, there are four machine gun points that can be determined, I don't know if there are others, we can't be sure." ”

After hearing Feng Siyang say this, Li Yunlong immediately understood that there must be special forces stationed in the other party's team, although he didn't know how many special forces-level guys there were on the other side, but one thing was certain, the other party must have arranged a warning ambush around the arming area that was difficult for ordinary people to find.

Feng Siyang didn't find this ambush, and if he touched the mechanism, he would alarm the opponent's first defensive ambush, and the opponent launched a counterattack in advance.

Li Yunlong suddenly laughed, "Let's go, go over with Lao Tzu and have a look, and when you see the specific armament, you will know what to do in the future." ”

Li Yunlong put his ear to the ground, and after listening carefully for a while, he took Feng Siyang and the others, leaning his body against the ground, little by little close to the fence near the mining area.

When there were still dozens of meters away from the fence, Feng Siyang reminded in a low voice, "We were discovered by the other party here. ”

Li Yunlong nodded lightly, and said with a smile, "You guys take a closer look at the grass in front of you, is there a thin line!" ”

Feng Siyang was stunned for a moment, then slowly lowered his head, almost touching his face to the grass roots, only to find a thin thread between the gaps in the grass.

Feng Siyang couldn't help but take a breath of cold air, this line of Sid, let alone at night, even during the day, if you don't pay attention to it, you won't see this thing.

"You two on each side, look for this line, remember, no one should touch this money, not even the weeds around this line, find the position where the two ends of this line are pointing, come back and tell me!"

"Yes!"

Several people replied in a low voice.

After discovering the alarm bell traction line laid in advance, Feng Siyang and the four of them realized that what they had learned in the special training was far from enough.

At the beginning of the special training, Li Yunlong talked about this similar situation, but he did not mention the use of this kind of thin line as a means. In fact, according to Li Yunlong, as long as you are careful enough, you can find this arrangement.

But in such a large area, who can guarantee that there will be such a design in what location?

experience, everything takes a long time to accumulate.

Li Yunlong also took advantage of this actual combat opportunity to give Wei Dayong and the others a word, "Have you seen it? If the enemy had designed such an early warning ambush, it would not have been too far from their garrison location, and of course, it would have been another way to arrange other precautions. ”

Wei Dayong nodded, "Then this thing, is it only arranged in this kind of place?" ”

Li Yunlong shook his head, "That's not necessarily, this kind of thin line, as long as it is a place that is easy to weaken the line of sight, it may be arranged, of course, it is also the kind of place where people or small animals are not often infested, otherwise even if this thing is laid out, there are birds and beasts often passing by, this thing will not play a big role." ”

Liu Sanxi nodded thoughtfully, "I understand, there are often devils in this place nearby, so creatures such as birds and beasts will not approach, and they will not destroy the ambush here, right!" ”

"Yes, Sanxi's analysis makes a lot of sense!"

Li Yunlong nodded with satisfaction, laughed, and pointed to Feng Siyang's position not far away, "See, if Lao Tzu is not mistaken, there are two machine gun sentry posts near the fence in those two directions, and the monk and Duan Peng will go over and kill the devils in those two sentry posts!" ”

"What about after you kill them?"

"After you kill it, you can step on this line casually!"

Li Yunlong pouted, Wei Dayong and Duan Peng split up and rushed straight to the garrison of the two machine gun posts.

In fact, it is not difficult to understand that a thin wire, as long as someone touches this thin wire, the bells hanging at both ends of the thin wire will be pulled.

As soon as the bell rings, it will alarm the machine gunners guarding the sentry station, and it is easy to spot a living person in such a close area.

As long as the Heavy fires, it will alarm other nearby sentry posts, and at this time, no matter how strong your combat effectiveness is, no matter how awesome you are, you will not be able to withstand the attacks of several groups of Heavy in turn.

Feng Siyang was defeated on this.

Wei Dayong and Duan Peng were very efficient, and they were worthy of being the two guys with the best martial arts skills, and they almost didn't have any sluggishness, and they killed the two devil machine gunners stationed at both ends of the dark line.

Seeing the two guys on both sides coming back, Li Yunlong stretched out his hand and directly tore off the thin line in front of him, abolishing the secret sentry defense.

When Feng Siyang came back, Li Yunlong asked with a low smile, "How about it, do you know how to solve this ambush in the future?" ”

Feng Siyang and the three guys behind him nodded again and again, "Instructor, it's still your clever means, kill the sentry posts at both ends, and this dark line will be useless." ”

"So, Lao Tzu has been telling you, I want you to analyze carefully, carefully investigate, what about you, you didn't even find this line, it alarmed the two machine gunners of the devil, you didn't die under this repeated machine gun fire, you are glad that your life is big!"

In the face of Li Yunlong's reprimand, Feng Siyang and several people nodded again and again.

"The instructor is still mighty, and the instructor will teach us a few more in the future!"

"I still learned a lot from the instructor, the previous theory and training, compared with the actual combat, the gap is quite big!"

"Okay, don't brag, Lao Tzu's strength is not for you to brag about!"

Li Yunlong stopped the boundless praise of these guys, and continued to instruct, "Next, there may be unexpected ambushes, all of which will open Lao Tzu's eyes wide, don't make the same mistake again!" ”

"Yes!"

"Understood!"

With Li Yunlong's personal guidance for the first time, Feng Siyang's confidence increased greatly, but he didn't expect to find a second dark line.

This time, Li Yunlong did not use Wei Dayong and Duan Peng, and directly let the two special forces led by Feng Siyang go over, but fortunately, these two boys behaved well, and they did not make any movement, so they loosened up the other two machine gunners.

Li Yunlong and a few people finally approached the fence wall, Feng Siyang was just about to stretch out his hand, but Li Yunlong shouted, "Siyang, what are you going to do?" ”
