The red-level rain hit the rainproof cloth in the greenhouse and the passage, like countless drumsticks falling on the war drum, and the sound made hit everyone''s heart.


    Xia Qing felt not only the impact of heavy rain noise, but also the magnetic field attack released by the passage of grass.


    The strong magnetic field attack made her unable to stand on the rainproof cloth in the passage and stare at the high altitude like the inspection team members who performed air defense missions. So, she simply climbed up the mobile signal base station tower more than 30 meters high, held a powerful sniper crossbow in her hand, and stood on the top of the tower with an umbrella over her head, with full hearing and visual ability, paying attention to the movements within 400 meters around.


    Xin Yu from Territory No. 8 was wearing a pitch-black protective suit, carrying a sniper crossbow, walked out of the snow-white building and came to the south passage of the territory, looking at the shelterbelt sky in the west.


    Huo Zhun in the territory of No. 11 also walked out of the greenhouse and raised the same sniper crossbow as Xia Qing; Shidu in the territory of No. 10 and Yuan Yan in the territory of No. 5 raised the sniper crossbow of No. 1, Zhu Li in the territory of No. 6, Tang Huai in the territory of No. 2, Tan Qi in the territory of No. 15, Wen Nengjie in the territory of No. 17, etc. also raised the sniper crossbow of exchange with Huo Lei.


    Crossbow arrows, bows, slingshots and stones are the main weapons used by humans during the period when guns cannot be used.


    Several birds that were not afraid of heavy rain rushed into this territory with a faint smell of flesh from the evolution forest and were shot down one by one by one by the air defense personnel.


    The grass that was blocked by the rainproof cloth and could not grow upwards creeped tenaciously, and the clusters of flowers bloomed were swallowed by the insects that drilled under the rainproof cloth. The reptiles who could not eat the flowers began to bite the insects stained with the fragrance of flowers on their bodies, and staged a battle between life and death.


    The area not covered by the rainproof cloth, the aggressive grassroots spread rapidly under the nourishment of the red-level rain. The grass buds drilled out and grew taller at a speed visible to the naked eye, and gradually approached the barrier groove of the rainproof cloth, which made people tremble and frightened.


    Under the dispatch of Yuehaiying, the Ninth Center employees carrying barreled potted pots rushed from Territory No. 7 to various territories to distribute aggressive herbicides, and the use of decayers was broadcast over and over again in the loudspeaker. The helicopter from Mount 49 took off and carried another potion configured by Zhang San to the western evolution forest.


    Western Evolution Forest, Mountain Area No. 46. Yang Jin, holding two wild boars, slashed and killed two wild boars, and jumped up. The tip of the knife accurately pierced the eyes of an evolutionary beast of unknown species. After turning over and landing, he quickly rushed to an out-of-control wolverine more than ten meters away. He cut off its neck with a knife, and then fought with an evolutionary wolf wearing a collar.


    Luo Pei, standing on the hillside, faced the beast tide and shot and killed the beasts that were rushing towards him with crossbow arrows.


    Hu Zifeng rushed over in a helicopter and sprayed purple-red potion downwards, and the beast tide and the twenty-five members of the Qinglong Team were bleeding at the same time.


    Twenty-five minutes later, the red-level rain gradually became smaller. Xia Qing, who shot a raptor, pressed the intercom button, and the loudspeaker on the tower of the twelve signal base stations in the northern area, and at the same time, Xia Qing''s calm and gentle voice came from, "The Qinglong Team has stopped the beast tide. The territories, investigation teams, and the ninth center, have replenished the potion in proportion, and waited for the lord No. 7 to issue an order on the edge of the blocking ditch, and immediately started spraying the medicine."


    The personnel responsible for spraying medicine in each territory stood by the weed wall with sprayers on their backs, holding the pressing rod in one hand and the nozzle in the other. The nozzle head aimed at the aggressive grass that had grown from one person''s height and had flower buds.


    In the territory of No. 25, Lu Fangchun and Wang Bo, who were recovering from the wound, stood by the window, staring at Xia Qing on the subway tower of No. 16 with a telescope, while holding their breath.


    Inside the weed walls on both sides of the passage, clusters of flower buds on the aggressive grass began to bloom. In the No. 7 Territory Laboratory, Zhang San, who was holding the walkie-talkie and staring at the temperature and humidity detector, finally pressed the button, "Start spraying!"


    With a command, more than 400 people and six drones standing by the three passages began to spray medicine at the same time. All the spray equipment that can be used in the northern area was used. However, the agent sprayed from this device will take at least 15 minutes to cover three grass-killing channels that are more than 60 meters wide and 12 kilometers long.


    After the rain stopped, the fragrance of flowers released by the aggressive grass in the unsprayed area spread rapidly in the air.


    Six minutes later, Xia Qing issued an early warning through the light spots that appeared in the glimmer night vision goggles, "The birds are coming, and ordinary people will immediately withdraw into the bunker!"


    The first to launch the attack was a laser cannon with a range of 400 meters in territory No. 7.


    The laser cannon can hit the target accurately, but it takes three seconds of cooling and charging time after each attack, which greatly limits the attack power of the laser cannon.


    Watching the birds enter the 2,100-meter range and approach quickly is a torture for the top snipers.


    arrive!


    The expressionless Xia Qing quickly took the trigger. The steel arrow shot a raptor with a wingspan of more than five meters away from her 500 meters away. At the same time, Xia Qing had turned around and shot the second arrow, hitting another raptor with a reaching 450 meters, and then turned around and the third one!


    The arrows in the territory were like rain, shooting towards the flock of birds pressing down like black clouds. At the same time, the small animals that hit the territory''s subway wall were electrocuted and twitched.


    In the third area of ??Mountain No. 49, the wild boars hidden deep in the cave raised their heads, their big nostrils continued to shrink, and turned to find the source of the smell. An evolutionary wolf wearing a protective mask and protective suit stepped on a little honey badger who was struggling with each other, quietly looking at the human territory that was trapped in chaos.


    "The concentration of the element of the kill has dropped below 28‰, and you can use a gun, kill..."


    Six minutes later, as soon as the loudspeaker in Tan Junjie''s territory reported the killing element data, dense gunshots rang out from the territory of the northern area.


    Black clouds surged at low altitude, and thinned and faded at a speed visible to the naked eye. Feng Wen, in the container house of the No. 14 territory, was disappointed to see Xia Qing standing on the iron tower without any injuries, holding a sniper rifle. She subconsciously took a deep breath.


    So smelly! !


    "Vomit-"


    Chen Cheng, an olfactory evolver in the territory of No. 3, couldn''t help but retching, immediately held his breath and put on a protective mask. He was wrong. He shouldn''t have used his sense of smell to detect the environment after the concentration of the killing element decreased.


    The stench emitted from the passage overwhelmed the scent of meat emitted by the aggressive grass. The uncontrolled birds in the flock of birds that were crazy about besieging the territory of the northern area began to flee, and the already out-of-controlled and crazy birds continued to attack the humans in the territory.


    In the territory of No. 3, the eyes of the boss Yang who had lost his ability to move gradually became clear, and the old wolf lying beside him showed a painful expression; Mountain No. 49, the little honey badger outside the iron net wall of District 3 gradually returned to clear and no longer shoveled randomly. The broken waist wolf wearing a protective mask retracted its big claws and stared thoughtfully at the animals that were electrocuted outside the iron mesh wall.


    After shooting and killing all the out-of-control birds and beasts that jumped into the wall within 2,100 meters, Xia Qing, who was standing on the tower, looked down. When she saw clearly the aggressive grass-killing appearance with the help of the lights on the sprayer''s head, her pupils contracted violently uncontrollably.


    Aggressive grass killing... melted? !


    Brother San prepared such a terrifying potion in less than an hour?


    He is truly worthy of being the boss of Blue Star Pharmaceuticals standing at the top of the pyramid! (End of this chapter)
