Japan is a typhoon-prone country. The underground drainage system in the Tokyo area was mainly built to avoid typhoon rainwater disasters. This system was started in 1992 and completed in 2006. It can be called the most advanced sewer drainage system in the world. It was built by
It is composed of a series of concrete vertical pits and the underground river is 60 meters deep.
Here, the meaning of sewers is definitely not sewer pipes in the Chinese sense. The sewers here are well-developed, and the transfer buffer zone can even reach ten meters or more. If it were during wartime, Japan's sewers would immediately change their roles and become
There is such a thing as a refuge.
Yan Fenghuo was lost when he entered the sewer, because there were no landmark buildings here, and he could not figure out the east, west, north, and south at all. The sewer was in the shape of a dense spider web, and it was so developed that it was breathtaking.
Yan Fenghuo, who was disoriented, did not feel any nervousness. He roughly identified the well-developed sewers in all directions and ran forward quickly along the sewer with the strongest drainage capacity. With this identification of direction, the sewers in front became wider and wider.
It seems to be reaching a pivotal position.
And this is indeed the case. Japan, which has a lot of rain from typhoons, has a complete sewer system. Among the dense sewers, there are reservoirs. This reservoir is like a water reservoir. When the water demand reaches a certain level,
At that time, it began to be released into the sea through the developed sewer system.
During the release process, some drains will be selectively closed to ensure that leakage does not occur and allows it to enter the sea according to the planned route.
When Yan Fenghuo stood at a sewer that was at an intersection, he clearly heard the messy footsteps coming from all directions, as well as the light from the tactical flashlight.
The Japanese Self-Defense Forces entered the sewer and chased and intercepted him.
The explosion in the restaurant caused huge casualties. All members of the Self-Defense Forces rescue team were killed in the explosion. When the explosion was over and the site was cleaned up, no trace of Yan Fenghuo was found, but what Yan Fenghuo did was seen
hands and feet.
There were cameras all around, but none of them showed Yan Fenghuo. Almost instantly, the relevant Japanese departments determined that the terrorists who caused the incident had gotten into the sewers, and immediately organized troops to enter the sewers to pursue and intercept them.
The ability to clearly find Yan Fenghuo's location was not due to the sensitivity of the Self-Defense Forces, but rather to the cameras placed in the sewers.
To ensure water storage and discharge and to prevent damage, Tokyo's sewer system also has camera equipment. This camera equipment is arranged at the connection between sewers and sewers to ensure continuous monitoring of sewer facilities.
Upon hearing the footsteps, Yan Fenghuo did not hesitate and immediately moved towards the direction he determined.
"Whoosh! Whoosh!..."
The sewers, which contained a large amount of stagnant water, made a splashing sound under the influence of footsteps. The sounds included those of Yan Fenghuo and those of Self-Defense Force soldiers, which made the usually silent sewers become noisy.
In a short period of time, Yan Fenghuo moved forward quickly for several hundred meters and could clearly see the light of the tactical flashlight at the corner.
This canal is extremely thick, with a height of more than ten meters. The water under the feet has also increased from 20 to 30 centimeters to about 50 centimeters deep, submerging the lower legs.
Standing still, Yan Fenghuo took a deep breath and lay down silently under the water to hide himself.
Fifty centimeters of water was enough to completely submerge him, and his location was exactly in the center of the two lights in the sewer. No matter where you looked, this was the most blurry area. A person hiding in the water, if he hadn't walked
It's absolutely impossible to spot it if you get close.
The lights suddenly turned on, and a six-person Self-Defense Forces tactical team ran over, with the tactical flashlight showing a cross-beam.
Tactical flashlight cross-search, this is the most basic tactical cooperation. Generally speaking, cross-search is suitable for search, especially for search operations in large empty rooms in urban operations. It is still suitable for placement in spacious sewers.
However, the penetrability of the strong light and the blurry light in this area cancel each other out, making it very difficult to detect underwater things.
Stagnant water is not clear water, it is turbid and full of discharged domestic water, industrial water, etc.
The strong light penetrated the water and passed by, but no trace of Yan Fenghuo was found. However, Yan Fenghuo, who was lying quietly in the water, was able to identify this tactical team through the feeling of the strong light on his eyelids and the sound of running water.
Distance to him: twenty meters.
The strong light of the tactical flashlight continued to flash, gradually moving away from Yan Fenghuo, one meter at a time. The light moved with the movement of people's footsteps. One meter further away meant that the distance between the Self-Defense Force soldiers and themselves was shortened by one meter.
A stream of water hit his head, and the sound of running water was very close at hand.
Yan Fenghuo, who was lying dead at the bottom of the water, slowly exhaled the air from his lungs to resist the upward floating force produced by the impact of the water flow on his body. Little by little, without leaving any trace, he still kept the motion of lying on the bottom of the water.
The air in the lungs was completely expelled, and a few imperceptible bubbles appeared on the rippling water.
Yan Fenghuo's body felt a strong sense of suffocation, but when this sense of suffocation arose, his head was extremely calm and sober. He understood clearly from the weak sense of power of the water hitting him from different directions.
Determine the cross-sectional tactical movement adopted by this self-defense force tactical team.
Except for one of them standing in the rear, the other five stood side by side on the cross section and searched forward. In other words, Yan Fenghuo, who was hiding in the water, would never be able to hide away silently. When the other party came across, he would definitely
Step on yourself and discover yourself.
Five meters, four meters, three meters...
Slowly, slowly, bit by bit, Yan Fenghuo's right hand took on the shape of a claw, resting on top of his head and waiting.
The Self-Defense Forces tactical team found no trace of Yan Fenghuo and continued to move forward according to the established tactical movement.
"Whoosh! Whoosh!..."
The middle member of the team raised his right foot and stepped onto the turbid water in front of him. But after he had done so, he suddenly discovered that the thing under his feet did not seem to be a flat and hard concrete bottom of the sewer, but something soft.
In an instant, the team members' eyes widened, and their pupils reached their limit: This is a hand, a human hand!
"Plop!"
"Wow!"
There was a huge sound of water, and the team members' bodies lost balance without warning, and they threw themselves forward without even having time to make any warning sounds.
"puff!"
A saber plunged into his chest, and the blood immediately mixed with the turbid water.
"Da da da..."
Deafening gunshots rang out instantly, and the submachine gun in the hands of the team member lying in the water spurted tongues of fire to the left side, knocking down his two comrades.
"Wow!"
The team member with the saber stuck in his chest suddenly turned over in his sleep, with the muzzle of his submachine gun pointed at the right side.
"Da da da..."
"Ah! Ah!..."
The two team members on the right were overwhelmed and fell into the water.
"Here! Here!" The team behind the scenes immediately shouted a warning through the radio and pulled the trigger without hesitation.
"Da da da..."
Amidst the gunfire, the corpse with a saber stuck in its chest suddenly stood up and rushed towards the team members at the rear.
"Puff puff puff..."
Countless blood splashed out, and the corpses fell on the rear team members under the influence of inertia.
The team member opened his body and saw Yan Fenghuo's cold face and the black muzzle of the gun in the opponent's hand.
"Bang!"
A bloody flower burst out from the team member's head, and his body fell backwards and fell heavily into the water.
Countless tactical flashlight lights poured into this sewer, mixed with urgent orders.
Yan Fenghuo turned his head and glanced back with squinted eyes, took off one of the men's equipment and put it on, then ran forward wildly.
