The leech monster shrouded in salt spray kept peeling off the expanding black leech on the outside, and the body composed of leeches continued to collapse. As the tentacles disintegrated, the leech people hanging on it struggled to get in, and the leech people who had not been contaminated with salt climbed into the leech pile, and the remaining leeches that had not been stained with salt climbed onto the leech people's body.

In less than two minutes, most of the black leeches that covered the entire lane spitted black slime and turned into a dry clump, and suddenly a grenade exploded next to the leech man. Directly triggered a dust explosion that permeated the entire area, and the powerful air wave blew Wang Zhiyuan away, sliding more than ten meters on the floor covered with slime and moss, and his head almost hit the front wheel of the truck.

Leech people were blown by the air wave near the entrance to the third-story warehouse, dragging their slime-dripping bodies towards the waterlogged entrance. Wang Zhiyuan received the picture from Robot No. 5, and regardless of his still buzzing head, he got up and stepped on the black leech corpses and slime all over the ground and chased after him.

Flowing through the corpses of black leeches like a quagmire, ignoring the entanglement of those black leeches that are not yet dead, Wang Zhiyuan and Robot No. 5 chased and shot at the same time. Several 12.7mm tracer bullets opened several large holes in the body of the black leech, and the leech man fell to the ground in one fell swoop.

The two tentacles that were tightly wrapped around the body and the head suddenly loosened, and the two tentacles protruding from the mouth of the head alternately dragged the dry skeleton towards the water-filled entrance. Wang Zhiyuan picked up the shotgun and aimed at the skeleton is three shots, and the corpse lying on the ground suddenly knelt up, blocking the dense steel balls with his broken body.

Robot No. 5's machine gun immediately completely exploded the body full of leeches, and Wang Zhiyuan saw with his own eyes that the leech man's head disappeared into a pool of stagnant water covered with green algae. A churning was evident under the green algae on the surface of the water, and Wang Zhiyuan immediately pulled out a grenade and threw it in.

The exploded water column and the whole group of leeches rushed down the three-story lane, Wang Zhiyuan hurriedly chased after it and fired a few shots, and the leeches rolled into the dark passage below. Reluctantly returning to the truck, Wang Zhiyuan pulled Sun Desheng aside and said, "This leech mutant has not been completely eliminated, and its head has escaped into the three-layer fuel reserve area. ”

Sun Desheng looked at the soldiers resting on the trucks around him and said: "Our ammunition has basically run out, and the vitality of these leech infections is too tenacious to deal with more difficult than those bugs, so let's find a way when reinforcements arrive." ”

Wang Zhiyuan asked Robot No. 5 to help pull the fast canvas and wipe the power armor, the salt and black slime were mixed together with black mud, and after thinking for a while, he said: "Battalion Commander Sun~ There must be a large amount of edible salt reserves here, so let the soldiers gather on one truck and send someone back to see if they can find a batch of sodium chloride for industrial use." ”

Sun Desheng explained a few words to the soldiers who transported the wounded, and came back and said to Wang Zhiyuan: "Red wolf ~ sodium chloride should have a lot of heating units in our camp, and I have informed them that they can transport as many as they can, and they can be transported here within two hours." ”

More than a dozen people used two hundred boxes of edible salt found from a warehouse, and the entrance to the third-floor passage was sprinkled into a silvery white, and the rest was poured on the third-floor ramp. Wang Zhiyuan threw a grenade into the stagnant water full of green algae and blew it up several times, and a large amount of edible salt was blown out of the water and rushed directly into the depths of the passage.

In less than two hours, two military trucks drove into the second-floor food storage area. Wang Zhiyuan finished replenishing the ammunition and said: "Battalion Commander Sun~ Let's drive the truck directly into the three-story passage, and then pour all these things into the stagnant water in the three-story fuel reserve area, and the problem will be easy to solve." ”

Before entering, Wang Zhiyuan found a flatbed truck and loaded more than a dozen boxes of sodium chloride, and the Demoman took out a C-4 bomb and stuffed it into the box, and set a time for the two of them to push the flatbed truck hard. The sound of flat wheels faded away, and after a muffled sound, a thick salt mist poured up the passage.

A group of men slowly descended the passage in a military truck, and the entire damp and mossy passage was turned into a snow-silver by the thick salt spray. The bright headlights of the military trucks shone past the stagnant leeches that had curled up everywhere on the ramp, and the half-arched tops of the passage were spitting slime writhing leeches, falling from a great height one by one, crushed by the wide wheels and sticking to the mossy driveway.

By the time we reached the third-floor oil storage area, the red paint sign prohibiting fireworks was already covered with moss, and the entire underground oil storage area was nearly one meter deep. The surface of the water is covered with a thick layer of green algae, and the water's edge is full of black leeches that are still struggling desperately.

Wang Zhiyuan patted the door of the cab and said: "There is no need to go down and take risks, and I don't know what these leeches eat, there can be such a large individual and quantity, first pour all the caustic soda in the car and see what you are talking about." ”

Sun Desheng got out of the car, kicked a ball of dead leeches into the water, and shouted: "All of them should be unloaded immediately and all the caustic soda should be poured in." After spending more than ten minutes pouring half a truck of caustic soda into the water, an unpleasant smell wafted up from the water, and all the green algae on the water immediately turned from emerald green to black gray.

Streams of black slime floated up the water, and the tactical lights shone on it, and a large number of black leeches crawled out of the water in the distance, desperately climbing up the damp walls.

After pouring half a truck of caustic soda, Wang Zhiyuan felt that such a large area of stagnant water was still not enough, so he poured half of the sodium chloride in the car.

Wang Zhiyuan patted the young demolitionist next to him and asked, "Do you have a way to safely create a sodium chloride explosion in this oil storage area?" The devil knows how many leech infections are hidden on this roof, and it is too dangerous to rush in. ”

The Demoman nodded, took some small silver tubes from his backpack, connected them to the wires, and said, "As long as there is not too much sodium chloride dust at each explosion point, it will not cause a dust explosion." The spare storage tank inside is designed to be strong, and there will be no problems with a small explosion. ”

After speaking, he shouted that half of the dozen boxes containing sodium chloride were poured out, and they were stuffed into the silver pipe connected to the wires, and he made an OK gesture to Wang Zhiyuan.

Sun Desheng pointed to the innermost part and said, "Just let your robot go to the control room and turn on the backup power generation system, and the drainage system will be activated, and the stagnant water here will be drained soon." ”

Wang Zhiyuan looked at the turbid water below, he didn't dare to go down, turned his head and patted the robot No. 5 and said, "Go control and open the backup power generation system and drainage system, and bring these boxes in by the way." Robot No. 5 immediately turned on all the lights in his body and said, "Understood~ Master Chief." ”

Under the illumination of more than a dozen lights, Robot No. 5 went into the water and dragged a string of sodium chloride boxes that were barely floating on the water surface and walked towards the control room.
