Chapter 473

People may be like this. When they are nervous, nervous and highly focused, it is a state, but once they relax and lose their attention, it is another state. The two states are quite different.

For example, this is the mercenary of the scorpion mercenary regiment in front at the moment.

Before the battle started, the mercenary of the scorpion mercenary regiment was relatively serious and responsible, more in line with the image of a sentry, especially a sniper sentry, and strict behavior. He was highly attentive, lay motionless in his position, and was extremely vigilant to inquire about almost all the abnormal situations around him.

At this time, he can definitely be regarded as a serious and responsible sentry.

However, once the battle started, his highly focused attention and almost antelope like vigilance immediately changed greatly. Even the nerves of the whole body seem to relax.

According to his thinking, the enemy is being attacked by his own people with fierce firepower. It is still difficult to escape. How can we have the strength and energy to make trouble here?

So, naturally, he relaxed his vigilance.

And people, sometimes, are so strange.

When the nerves are tight and the attention is highly concentrated, there is nothing wrong with the body. But once you relax, that's not the case. This is especially true for soldiers and snipers like him who play latent and vigilance for a long time.

Once you relax and relax your vigilance, if you lie down in a place for a long time, it will either itch here or hurt there, or because you lie down in a place for too long, either uncomfortable here or uncomfortable there. You always want to move, scratch, stretch and move.

And once this problem occurs, it will be endless. For a moment, it can't stop at all.

This is what the special combat team member expected, and it is the fighter he is holding a sniper crossbow, paying high attention and concentrating on waiting for.

Sure enough, the sniper of the scorpion mercenary regiment didn't let him wait too long and didn't disappoint him.

In fact, after a minute or two, the sniper of the scorpion mercenary regiment seemed a little impatient.

However, seeing that he shook his head and moved his neck as if nothing had happened, then his body moved slightly to the right, as if he had changed his position. Then, the butt of the sniper rifle may have hit his chest and armpit, so his hands involuntarily used force to support his body, and then put on the most appropriate and comfortable lying position.

However, the most suitable and comfortable lying posture, he is no longer blessed to enjoy.

Because, just when he supported his upper body with both hands and planned to change his prone position, a crossbow and arrow came quickly through the air, ending his life and all his conscious active actions in a very short time.

Almost at that moment, the Chinese special warfare team member who was already ready to go, decisively pulled the crossbow machine, a crossbow and arrow, under the direct action of the physical energy of the sniper crossbow, went straight to the just exposed throat position of the scorpion mercenary regiment, screaming extremely accurately.

Almost in the blink of an eye, the crossbow and arrow that fell into the throat quickly cut off the arteries and vocal cords of the sniper of the scorpion mercenary regiment.

For a moment, the blood gushed, and the cut vocal cord prevented him from making an emergency call for help and early warning. Due to the infinite desire and fear of life, he forgot to shoot the early warning signal immediately, but immediately put down his sniper rifle, tried to stop the outward spray of blood with his own hands, and implemented the final powerless struggle and self-help.

However, he was cut off by a crossbow and arrow. In a hurry, no matter how frightened he struggled and hurried to save himself, the result was futile. Because, since the crossbow cut off his artery, his life has entered the last few seconds, at most more than ten seconds of countdown.

The elite of this team of Chinese special forces have no time and patience to wait quietly or appreciate his dying struggle. Almost at the moment when the crossbow shot into his throat, Chen Zheng and his five Marines immediately took action, quickly crossed the swampy humic layer, and quickly rushed to the secret road behind the sniper of the scorpion mercenary regiment.

Feilong also took two and three steps. After quickly crossing the swampy humus layer, he climbed up the hidden position of the sniper of the scorpion mercenary regiment. After determining the death of the other party, he quickly occupied this extremely important key position and was responsible for the observation and vigilance of the on-site operation together with the special combat team member led by him.

Chen Zheng and the five good Marines who quickly entered the secret passage, while moving forward carefully, immediately devoted themselves to the extremely professional and delicate work of fixed-point blasting.

This is an island of volcanic rock.

Hundreds of millions of years ago, volcanoes occurred frequently due to the violent movement of the earth's crust. In the frequent occurrence of volcanoes, the hot lava gushes out from the depths of the earth through the deep sea. After cooling, it solidifies and takes shape. Thus, the most primitive volcanic rock structure framework of the island is formed.

The commanding height area to the south of the island was the main ejection point during the volcanic eruption that year.

After the hot lava is ejected from the ground, the high temperature inside needs to diffuse outward, so that a network structure similar to honeycomb and with many fine pores is formed inside the rock. Although the rock with this structure has many natural advantages that can not be replaced by other materials in industry. However, strictly speaking, it is not a permanent material with solid and stable structure.

In other words, the volcanic rock looks very solid, sharp and even ferocious on the surface, but in fact, many places are hollow, can't eat much force and can't stand much pressure. Once the destructive force is beyond the range of their own materials, their internal structure is likely to cause destructive collapse.

Chen Zheng, who is familiar with the way of blasting, certainly knows the performance and characteristics of this material like the back of his hand.

When he entered the dark way, he immediately reacted and had his own idea.

He is taking a big risk.

He not only wanted to blow down the enemy's artillery positions, but also wanted to eat even the last base camp set by the enemy on the commanding height.

After all, the opportunity is rare.

They took great risks, avoided the enemy's main force and intensive firepower, and finally reached the position closest to the enemy's hinterland core. If they don't do a hard job and give the enemy a devastating lesson, it will be a shameful waste.

But here comes the problem.

For the commanding heights of the volcanic rock structure in front of him, and the five Marines he led, the use of manpower to carry explosives is too limited, it is a little pitiful.

The extremely limited explosives will blow down the huge thing at present, which will not only test Chen Zheng's blasting skills, but also his courage and determination.

At this time, if you are too greedy to chew and eat, you try to collapse the main peak of the island with limited explosives. In that case, I'm afraid we have to say whether we can achieve our goal and complete the task in the end, and the worst thing is that we may not be able to destroy even the enemy's artillery positions.

If that's the case, the gains will outweigh the losses and the success will fall short.

For a moment, Chen was in a dilemma.

However, at the critical moment, the character always plays a decisive and key role.

At this time, I have to say that his calm and prudent character once again deeply affected his choice.

Under the tight time, after some reflection, Chen Zheng finally gave up his decision to do one big vote, and everything was based on safety. After all, in his view at the moment, it is better to break one finger and kill ten people than to destroy one. Moreover, the enemy's artillery positions are still frantically firing shells and pouring fire on their comrades in arms.

It is urgent to destroy the enemy's artillery positions. Time is pressing and the situation is urgent. Of course, it is also very important to destroy the enemy's last base camp, but at present, it is not a very urgent task.

Do important and urgent things immediately; Important and less urgent things can be done later.

This is the principle that special forces strictly abide by when they perform their tasks.

Supported by these two reasons, Chen Zheng quickly made his own choice.

After making a quick decision, Chen Zhengzheng led five Marines to act separately, looking for key points in the dark road and reasonably loading explosives.

In the world, any building, even the geological structure protruding from the ground, has its main load-bearing frame. In other words, they all have their most vulnerable side. Whether it is skyscrapers hundreds of meters high, or towering mountains that span the East and West and cut off the north and south, it is almost the same.

As long as you can find the most core and key point, or an area, and then fill explosives reasonably, it is very possible to shake the seemingly impossible giant with the smallest energy.

The blaster in the special forces, in many cases, is specialized in learning to find the key point and blasting point, and then reasonably control the amount of explosives, so as to complete the perfect blasting tasks again and again.

Because the volcanic rocks belong to hollow structure, which is strong in the outside and dry in the middle, and natural lines have been formed when the volcano erupted that year. These lines are distributed in a network and spread around. Once they have found the key point, Chen Zheng is sure that they will use the extremely limited explosives carried by the team members to destroy the enemy's small artillery position.

Generally speaking, ordinary blasters can only blast once.

In fact, after finding the blasting point, fill a large amount of explosives in one position, and then use the energy released by a large amount of explosives to complete the blasting task.

Of course, such blasting is often based on the waste of explosives.

However, at this time, Chen Zheng's explosives are very limited. At the moment, they want to use one as two. If there is a waste of energy, it is not only extravagant, but also shameful and even damned.

Fortunately, they, who are familiar with the way of blasting, have long been proficient in playing fixed-point blasting.

This time, Chen Zheng adopted a serial blasting method with extremely high skills, and he knew the blasting materials and the power of the filled explosives like the back of his hand, and even could calculate accurately.

The blasting principle is not complicated.

Under normal circumstances, ordinary fixed-point blasting is to fill explosives at a key point, and then detonate at one time to complete the blasting task. As for the final blasting effect, no one can guarantee it. It's like gambling. Sometimes the effect will be better, sometimes worse, and sometimes the effect will be surprisingly poor. This is also very possible.

In fact, the reason is not complicated. One-time blasting is like buying and selling with a hammer.

It's good or bad all at once. Whether it's good or bad, let it be fate!

In fact, the blasting structures are not all visible to the naked eye, and sometimes there are some hard stubbles. In the process of blasting, these stubbles can sometimes be bad. It can absorb a lot of blasting energy, but the structure will not be seriously damaged.

This is also the main reason why the effect of blasting is still not ideal even if it consumes a lot of explosives.

However, as a professional and highly skilled blaster, they know how to solve these hard stubbles.

This is the so-called look at the trend, look at the grain, look at the structure.

After understanding these, the blasting key points, possible points of hard stubble and the distance between each blasting point shall be accurately calculated, and then the explosives shall be reasonably filled at each blasting point.

Of course, after completing the loading of explosives, the blasting sequence of each blasting point is also very particular, and there is a strict sequence.

To be exact, this is almost the blasting sequence determined according to the direction of energy propagation during blasting. In other words, when the first blasting point explodes, the blasting point at the limit of the range to which its energy is transmitted, or the blasting point at the hard stubble encountered in the process of energy transmission, detonates immediately, and so on. Thus, the blasting energy can be effectively extended to the key points or key areas, so as to maximize the energy utilization, so as to achieve the maximum blasting effect of limited explosives.

This is the so-called serial blasting, a highly professional blasting method.

Chen Zheng, who knows the way of blasting, plays with blasting all year round, often ponders blasting methods and calculates blasting effects, happens to master this blasting skill skillfully.

Under the urgent situation of time and situation, he led five Marines to start the implementation.
