[Continue the three watches today, it's nothing, so many rewards from friends, so many recommended votes, I was moved. ] 】

"Brothers, work, grenades, instantaneous explosions, start. ”

Lin Qingshan greeted.

I saw that dozens of Siberian tiger warriors in the field took off the backpacks behind them in a uniform manner, and each of them took out a grenade from it.

Pry it open with a flat screwdriver and remove it with a screwdriver.

Then began to carefully modify the time of detonation of the grenade.

The scene was quiet, and everyone couldn't help but subconsciously stay away from these soldiers, afraid that someone would accidentally blow it up.

A few minutes later, all the fighters stood in line again with modified grenades in their hands, which were indistinguishable from the outside.

Lin Qingshan pointed to the water surface and said: "Double W-shaped cross thunder net, enclosing a circular water area, a layer of thirty centimeters above the water surface, and a layer of fifty centimeters below the water surface, a double-layer thunder net. Begin. ”

The soldiers of the Siberian Tigers immediately began to act, with a clear division of labor and rapid movements.

In order for the grenades to enter the water, those grenades that need to be sunk 50 centimeters underwater, each of which is packed in a double-layer signal balloon, wrapped in balloons, and then tightly wound with fishing line to prevent waterproofing.

This net is double-layered, with the same formation above and below. A total of ten grenades are needed on a single floor, one at each node in the shape of a w.

And because the water area has a diameter range of more than ten meters, Lin Qingshan was afraid that the lethality was not dense enough, so he used a cross-type double W shape, so as to do so. This explosion, that is, twenty grenades exploded together.

Not a joke, the power of the center of the explosion is simply unpredictable, not to mention the explosive force, just the combustion temperature at the time of the explosion, I am afraid that it can reach a high temperature of tens of thousands of degrees. It can even burn the stone in an instant, turning it into a glazed shape.

Just a layer of thunder net was enough to kill the big snake on the spot. And Lin Qingshan, for the sake of insurance, has one layer under the water and one layer on the water. It turned out to be a double-layered thundernet.

Lin Qingshan explained with a smug face:

"The double W-type mine net can be said to be the most dense physical mine net. As long as you are in the W area, at any node, you will be subjected to the most terrifying concentrated bombardment. The layer of thunder nets underwater, the lead is in the form of a double W cross, which is only a little sparser than a fishing net, but such a big snake, which line the body touches, will be triggered. ”

"The lead line in the water below is set loosely, which can achieve a theoretical delay of only half a second at most. Half a second was enough time for the serpent to trigger an underwater mine net, and its head popped out of the water. According to inertia, the big snake will continue to rush upward, then it will touch the most sensitive upper thunder net, which can achieve the effect of exploding underwater and above at the same time. ”

Li Xun nodded secretly, and said in his heart that although Lin Qingshan's emotional intelligence is very low, his behavior is reckless. But with regard to small-scale tactical command, it is simply a well-deserved talent. This is a simple double-layered thunder net, in which the physics used is so advanced and the professional knowledge is so profound that ordinary people would not think of this tactic at all.

Lin Qingshan pointed to the soldiers who were nailing wooden stakes into the soil around the shore of the water cave and said:

"The circle of octagonal wooden piles is a device for hanging thunder nets. The fuse is passed through the grenade and then tied to the stake, which is driven by an octagonal shape so that each grenade explodes at the same time, without one after the other. The use of octagons is also the most scientific way. ”

Xu Qianyun said: "Then what if it hasn't touched the thunder net yet, and the thunder net explodes?"

Lin Qingshan asked rhetorically: "It didn't touch the thunder net, how could it explode?"

"There is a shock wave underwater, and when the big snake moves slightly, it is a stormy wave, and the water wave surges upward, and the lead is also resistant, and the undercurrent is beaten, triggering the thunder net?"

Lin Qingshan said with a smile: "So when it comes to underwater leads, a relatively loose mode will be used." The underwater lead is relaxed to the center and points out of the water, and the thunder ring will be straightened. And you think that the waves can trigger the thunder? You're naïve. Even if you throw a grenade, you need to pull the thunder ring vigorously, which is a kind of protection device, that is, you are afraid of accidentally pulling the thunder ring apart when carrying the grenade. ”

"How much effort does it take to pull the thunder ring?"

"It takes at least five kilograms of strength to pull the thunder ring apart. Do you think that the impact of water waves on the lead can cause more than a pound of force? The lead is thinner than the kite line, and the resistance is almost negligible. ”

Xu Qianyun nodded and didn't say anything more.

Lin Qingshan continued: "Of course, in view of the fact that this big snake cannot be said in the same way, in case this thunder net does not kill it at once, and causes damage to our army, then we will have to go to the second layer of insurance now." ”

Li Xun asked, "What is the second layer of insurance?"

"Anti-tank mines. ”

Lin Qingshan spoke, pointed to the mouth of the lake shore above, and said, "We will set up anti-tank mines on the edge of this lakeshore. Mines are placed at the bottom of the lake, which is not easy to detonate, because it may be upright and cause a suspension in the air. But if it wants to run, it must first climb out of the lake and into the dry riverbed. Therefore, it is inevitable to put the upper body on the shore of the lake and then move it. I will go around the shore of the lake and place anti-tank mine arrays. ”

Li Xun asked with interest: "Are anti-tank mines powerful?"

Lin Qingshan said of course, and then said: "You must know that to trigger an anti-tank mine, it takes more than 180 kilograms of pressure. It has to be powerful. What kind of material is that tank? Just kidding, it's harder than pure steel. But an anti-tank mine can blow up the Iron King Eight to the bottom, destroying all the internal facilities and the outer tracks. The heat can even melt the tracks. How could the flesh and blood of the great snake be able to stop it?"

Li Xun turned his head to look at Expert Xu, whose face kept flashing with hesitation, and said with a smile: "Then look at this meaning, you can't catch it alive." ”

Expert Xu frowned, and laughed dryly: "Xiao Lin, is there a way to paralyze it, but what about not dying? ”

Lin Qingshan glanced at Lao Xu in annoyance and said, "Then I only have this way, either let it die or let it run." You said lightweight, a snake tens of meters long, that you can catch alive if you want to?"

Expert Xu looked at the soldiers who were erecting wooden stakes and said: "Don't want anti-tank mines, and don't want this layer on the water, just a single-layer underwater mine net is enough." This layer of thunder net is enough to paralyze it, and as for life and death, then it is really life and death, wealth and prosperity. ”

"Hey, I'm talking about you......"

Lin Qingshan's face was displeased, and he pointed at Expert Xu and was about to say something.

The captain Zhang took a step forward and looked at Lin Qingshan with a cold face.

Lin Qingshan's words were immediately held back again, and he was resentful in his heart.

For this big snake, I have two brothers who have died, so I must want to let it die to avenge it, so this double-layer double-W thunder net can be described as extremely domineering.

But Lao Xu and everyone other than the Northeast Tiger Special Operations Brigade all wanted to live.

This is a contradiction.

However, it seems that Lin Qingshan can't disobey Lao Xu's intentions.
