On the tenth year of the natural disaster, I went to farm with me

Chapter 628 Red Weeds and Evolved Pathogens

Xia Qing steadied herself, held her breath, and continued to move forward despite the discomfort caused by the magnetic sensation. She wanted to see what these little gadgets that had just emerged from the ground less than two centimeters could do!
After crossing the quarantine zone and reaching the edge of the high-risk zone, Xia Qing picked up a stone and threw it at the bright red grass. The grass was bent by the stone, but there was nothing unusual about it. It seemed that it was either in the stage of brewing an outbreak of self-evolution, or that the grass had not evolved physical attacks.

She immediately dug out the nearest blade of grass along with the soil at the roots and put it in a sample box. Then she flew up 500 meters to the entrance of the bear cave and shouted to Yue Haiying without landing, "Brother Yue, don't get within 200 meters of the high-risk area."

If those weeds grow bigger, they may evolve chemical attack methods.

Yue Haiying shouted back, "Understood, be careful!"

Xia Qing flew back to the territory on a single-person flying vehicle. Seeing Ji Li waving at her on the northern isolation zone, she immediately landed on the northern isolation zone.

After Ji Li's inspection, Xia Qing took the sample into Territory No. 3. When she handed it to Yan Long who was beside Zhang San, she shook her mobile phone slightly towards Zhang San.

Of course Zhang San saw Xia Qing's actions. After entering the laboratory, he opened his mobile phone and took a look, and was stunned for half a second.

Zhang San moved quickly, and in less than ten minutes he came back with two test reports. "The damage of this bright red weed killer has not been detected yet, but the OS methylphosphonothioate remaining in the soil and the rain killer have worked together to promote the evolution and rapid reproduction of Salmonella in the soil."

Zhang San propped up the legs of his glasses with his report and calmly ordered, "High-risk areas need to be sprayed with disinfectant immediately, and rainwater flowing out of high-risk areas also needs to be disinfected as soon as possible. Xia Qing, how many round trips does your individual aircraft have enough fuel?"

"It's not enough to fly a round trip." The individual aircraft consumes 10 liters of fuel for a flight of 45 kilometers. It is simply a fuel-guzzling monster.

Zhang San asked Ji Li, "Is there any aviation fuel left in the territory?"

Individual flying vehicles use the same fuel as helicopters.

After Ji Li nodded, Zhang San immediately ordered, "Go get enough fuel for two round trips and give it to Xia Qing."

After Ji Li left, Zhang San asked Xia Qing again, "Can you use a drone to spray pesticides?"

Xia Qing shook her head, "No."

Zhang San immediately ordered Zhang He, "Immediately send the second respondent to the high-risk area."

After Zhang He nodded and left, Zhang Sancai said to Xia Qing, "You take the drone and the chemicals and fly over there. First, disinfect the pond below the heavily polluted area. Then, run over there and use the drone to disinfect the dangerous area. Use the drinking water stored in the bear cave. Be careful."

"Understood." The stored drinking water is, of course, the hot spring water hidden in the valley. It is raining heavily now, and the open water source cannot be used directly. Xia Qing whispered to her idol, "Third brother, can I exchange some defensive potions or protective mask filters with you? The three of Yue Haiying are stationed in the bear cave and need more equipment."

Zhang San, whose face turned pale and blue, rolled his eyes at Xia Qing who was grinning foolishly, then turned around and went back to the laboratory.

Although the idol didn't say anything, Xia Qing knew that it was done. When she followed Zhang Song to get the medicine, she heard him constantly talking about the dangers of evolved salmonella. In fact, Xia Qing had learned this knowledge many times from Broken Waist Wolf and had memorized it long ago, but she didn't interrupt Zhang Song.

"...Ordinary Salmonella entering the animal body will cause abdominal pain, vomiting, arthritis, and meningitis; Evolved Salmonella entering the organism will quickly cause multiple organ failure; infection with super-evolved Salmonella will cause irreversible damage to the body..." Zhang Song handed the potion to Xia Qing solemnly, "Evolved bacteria are multiplying rapidly, polluting the soil and water sources, and promoting weeding. Our territory is located downstream of Mountain No. 50. Once sewage containing super-pathogenic bacteria flows into the territory along the river, the consequences will be disastrous. Miss Xia, please."

"Don't worry, Brother Song. I led my men to build the drainage ditches and sewage pits in the highly polluted areas. Even if it rains heavily for three days and three nights, not a drop of polluted water will flow out." Xia Qing calmly took the medicine and the large box containing the drone and stuffed them into his backpack. Yanlong came over with a black bag and handed it to Xia Qing.

"This is the defense material the lord gave you. Be careful."

"Don't worry, Sister Yan." Xia Qing stuffed the supplies into the backpack, walked out of the house, and stepped on the individual flying vehicle filled with fuel. Instead of going directly to Mountain No. 50, he first returned to Territory No. 3 before rushing to Mountain No. 50.

After watching Xia Qing fly away, Yanlong returned to the inner room inside the monitoring room and took out her protective mask. Huo Zhun was puzzled, "Why are you wearing a protective mask?"

Yanlong asked calmly, "Didn't I hear the Lord say why there was a change in the high-risk area of ​​​​Mount 50?"

The monitoring room could hear the sound. Huo Zhun recalled, "What acid ester and chlorine element work together?"

Yanlong glanced at him and said, "He said the abbreviation. The full name is O-ethyl-S-(2-diisopropylaminoethyl) methylphosphonothioate, which is the VX nerve agent."

Huo Zhun didn't understand the chemical name, but he certainly knew the famous VX nerve agent, which is known as one of the most deadly chemical weapons. However, "VX is in the experimental area of ​​Hill 50, why are you wearing a protective mask?"

Yanlong was too lazy to talk, so he put on a protective mask and walked out.

Huo Zhun scratched his head. Could it be that VX has a bad smell? And how could the smell come from such a long distance? It was outrageous...

On the way to the third peak of Mountain No. 50, Xia Qing saw a man in protective clothing running quickly along the edge of the valley between Mountain No. 50 and Mountain No. 49.

No need to ask, this must be the speed evolver from Territory No. 7 sent by the third brother, Erying.

Xia Qing arrived first after starting late. When she landed at the entrance of the bear cave, the rain that had stopped for more than half an hour began to pour down again. Xia Qing shook off the water on her body, and after entering the bear cave, she handed the black bag that Yanlong gave her to Yue Haiying, "These are three new protective masks. Brother Yue, you all put them on. The red grass has evolved into an aggressive one and is likely to release poisonous gas."

Yue Haiying took the protective mask and asked, "The rain has started again, and the level of harmful elements is still rising. Can we still use drones to spray pesticides?"

"No." Using drones to spray pesticides when it rains will not only reduce flight efficiency, cause mechanical failures, and cause problems with visual communication, but the sprayed pesticides will also be quickly washed away by the rain and will not be effective in killing evolved pathogens.

"It's about to reach the red level!" Yu Shou shouted as he stood outside the bear cave with an umbrella, collecting rainwater to test the content of harmful elements.

Xia Qing and Yue Haiying frowned at the same time.

In the red level of rain, whether it is weeds that may have developed chemical attack capabilities or evolved pathogens, they will grow and reproduce rapidly!
