Chapter 150 Biological mosquito repellent method The flood lasted for three days and three nights. It was not until the last wave of the flood passed safely that the members of the Pet Guild, who were covered in mud, breathed a sigh of relief. Large areas of yellow mud appeared in places that were flooded. The Beast Guild dispatched large water-type pets to completely clean the yellow mud. After the flood, many things in the nursery were no longer usable. It needs a lot of cleaning up. After the flood, there will be a great epidemic, and the night mosquitoes begin to multiply. If you go out without protection now, you will definitely get a big pimple from the night mosquito bites on the exposed parts of your body. How to prevent night mosquitoes has become a difficult problem for the pet guild and the breeder guild. At this time, Zhang Lingxue asked Ye Bai to go over.
She was wearing a white dress and rabbit ears on her head. Two Thunder Rabbits are helping Zhang Lingxue organize information. “Ye Bai, the breeders’ union has sent us a request for help. After the flood, mosquitoes have become rampant in the dark night. We need to brainstorm solutions to find solutions.” "I'm still sorting out the information on the positive and negative rabbits, please go there for me." “I am the honorary elder of Jiaying City Cultivator Union. Since they come to ask for help, please go there for me.” Zhang Lingxue has been sorting out information all night recently, and the time for the inspector's visit to conduct the assessment is gradually approaching, and there is not much time left for Zhang Lingxue. However, the matter of cultivating the Family Guild was very urgent, so Zhang Lingxue could only ask Ye Bai to go there on his behalf. The Breeders Guild is a subsidiary organization of the Pet Guild, and its office is located near the Pet Guild. There is a five-story building here. The first floor is the office hall, and the second floor is a place for cultivating pet animals. The third to fifth floors are where the members of the Nurturers Guild work. At this time, the members of the Breeders’ Union were all crowded in the large conference room. Liu Chenggong, the president of the Breeders Union, and Wang Jinyin, the president of the Pet Union, sat side by side. “Everyone, night mosquitoes have been raging recently, and we must effectively control the number of night mosquitoes.” “Do you have any good ideas?” Liu Chenggong is extremely smart. There is another huge red bump on his bare head. It looks like it was bitten by a mosquito in the dark night. From a distance, it looks like it has horns on its head. Wang Jinyin thought about all the sad things before he could not hold back his laughter. “I think we can use physical mosquito repellent method.”
“Build a large-scale mosquito repellent device to reduce the number of night mosquitoes.” Suggestions were immediately made. Liu Chenggong glared at the man fiercely: "You think the night mosquitoes are just ordinary mosquitoes? They are extremely cunning." “A night mosquito is the size of a fist. You can imagine how big a mosquito repellent device we have to build.” Liu successfully vetoed this proposal, and someone immediately suggested whether chemical mosquito repellent could be used. Successfully achieves the purpose of chemically repelling mosquitoes by spraying an odor that is disgusting to night mosquitoes on the body. Liu Chenggong thought for a while and shook his head: "No, the night mosquitoes are not ordinary mosquitoes, and if the number of night mosquitoes continues to multiply." “There is a high possibility of mosquito infestation.” “By then, the entire Jiaying City will be choked by mosquitoes that cover up the sky and the sun, making it impossible for any grass to grow.” “It is also easy to give birth to high-level night mosquitoes.” “We have to think of a way to eradicate the night mosquitoes.” At this time, Wang Jinyin saw Ye Bai, who was hesitant to speak. “Ye Bai, please tell me your opinion.” When everyone saw Wang Jinyin nodding Ye Bai in front of everyone, they immediately started whispering. “What insights can a young man like him have?” “Yeah, what kind of way is he? A minor dares to attend our meeting.” “I remember that when we posted, we all sent it to respected breeders. How could we send it to a minor?” Everyone was gloating about his misfortune. They didn't think Ye Bai could say anything. Ye Bai took the microphone and adjusted his voice: "I personally think that we should approach it on both sides." “Use chemical mosquito repellent and biological mosquito repellent to go hand in hand.” “Chemical mosquito repellent can solve the personal problem of citizens being bitten by night mosquitoes.” “Biological mosquito repellent can solve the problem of night mosquitoes from the source.” After hearing what Ye Bai said, Liu Chenggong suddenly became interested: "Then what do you think of biological mosquito repellent?" “We have tried poison dart frogs and giant frogs before, but unfortunately they don’t seem to be interested in night mosquitoes.” Ye Bai shook his head: "They are not the best choice." “The best choice would be a dragonfly-like beast.” “They are the natural enemies of night mosquitoes.” “According to statistics, dragonflies can eat a thousand mosquitoes every day, and dragonfly larvae can eat three thousand mosquito larvae every day.”
“We can completely solve the problem of night mosquitoes through this direction.” But at this time, Liu Chenggong asked another question: "Ye Bai, I am very interested in biological mosquito repellent methods, but one thing is, will we introduce dragonflies and exotic beasts in order to eliminate a pest, and then... This will lead to the proliferation of dragonflies and exotic beasts, and they will become new invasive species." Ye Bai nodded: "I have also considered this issue." “We can proceed in two ways. One is to screen for dragonfly beasts that have poor reproductive ability but can eat night mosquitoes, and the other is to screen for dragonfly beasts that are large in size.” “Unlike night mosquitoes, dragonflies and other beasts are very large, so it is relatively easy for us to catch them.” "You can think of it this way. In the pet store, dragonfly beasts and night mosquitoes are sold separately. Do you think the price of the dragonfly beast is higher, or the price of the night mosquito?" Everyone responded one after another that it was a dragonfly. Ye Bai shrugged his shoulders at this time: "Isn't that okay?" “The value of dragonflies and exotic beasts is high, and if they are valuable, people will catch them.” “We can definitely build an industrial chain for dragonflies and exotic animals. Firstly, we can increase jobs. Secondly, we can increase fiscal revenue by selling dragonflies and exotic animals.” “Think about it, everyone, do you still think that dragonflies and strange beasts will become rampant?” After hearing Ye Bai's explanation, everyone felt that Ye Bai's words made sense. After all, night mosquitoes are pests, worthless, and only about the size of a fist. The dragonfly beast is at least one meter tall, with wings as thin as cicada wings and sickle-like claws, which makes it windy when taken out. Isn’t this night mosquito the natural feed for dragonflies and other beasts? Thinking of this, everyone's minds became active. “Now I have another question here. We have discovered hundreds of species of dragonflies and beasts.” "How do we find dragonfly beasts suitable for cleaning up night mosquitoes from this huge family of dragonfly beasts?" "We have no time for trial and error." Liu Chenggong said sternly. “President Liu, we can do this. First, we will investigate the dragonfly beasts and see which dragonfly beasts have a cool appearance, are large in size, and feed on night mosquitoes.” “Then we can select first, and after selecting five groups, we can conduct parallel experiments.” “We can carry out experiments next to each river, so that we can screen out suitable dragonflies and exotic beasts, and we can also prioritize the removal of some dark night mosquitoes and suppress the reproduction rate of dark night mosquitoes. In this way, we can try our best to completely expel the dark night mosquitoes.” “By the way, the dragonfly beast must have a good character, otherwise it may become a difficult alien species as President Liu said.” Ye Bai's words were recognized by everyone. Now everyone looked at Ye Bai with curiosity. Whose disciple was this guy? The problem they found difficult was solved by Ye Bai in one go. The behemoth of the Breeders' Guild immediately took action and began to spin. Through comparison, the staff screened out the larvae of five species of dragonflies. By this time, Ye Bai had become Liu Chenggong’s guest.
“Reporting to the president, we have screened out the larvae of five dragonflies and strange beasts, and this is their information.” Liu Chenggong’s secretary, Miss Zhang, put the information on the table. Liu Chenggong did not look at the information, but handed it to Ye Bai. “Ye Bai, please help me check it out.” Ye Bai opened the information and took a look. The larvae of these five kinds of dragonflies and strange beasts are respectively. Flame Dragonfly: The larvae of the Flame Dragonfly usually live in rivers with higher temperatures. When they are still larvae, the Flame Dragonfly is still water-attributed. Once it evolves into a Flame Dragonfly, it will become a fire + wind attribute. Thunderfly: The larvae of the thunderfly. They will generate high-voltage current in their larvae form. Usually, where the thunderfly is, there are usually no other aquatic creatures. Brute force waterhopper: The larvae of Brute force dragonfly is also the largest dragonfly-type animal. When it was still a waterhopper, it was half a meter long. When it evolved into Brute force dragonfly, its wings alone were four meters long. long. Breeze dragonfly: The larvae of Breeze dragonfly. It is the smallest dragonfly-shaped animal. They are very popular among girls. Grass water dragonfly: The larvae of the grass dragonfly. There is a weed-like thing on the top of their heads. They have the function of purifying water quality. Ye Bai saw the thunderfly at a glance. According to the system prompts, the thunderfly was the most suitable beast to clean up the night mosquitoes. “We must first rule out the Blazing Water Grasshopper. This guy has an explosive personality and is difficult to control.” “Once they evolve into flaming dragonflies, will they affect the fire safety in Jiaying City?” “The second thing that needs to be eliminated is, I think, the breeze mosquito. This guy is not very practical, but it looks pretty, but it is not very useful for us in controlling the disaster of night mosquitoes.” “With the remaining three groups of dragonflies, I think we can start experiments.” “We divided the Jiaying River into three sections and released these three types of watergrass respectively.” “First, control the number of night mosquito larvae at the source.” “How about we clean up the number of night mosquitoes after they evolve into dragonfly-type beasts?” Ye Bai suggested to President Liu and President Wang. “There’s nothing wrong with me.” President Wang and President Liu both nodded. “Just execute everything according to your plan.” Citizens of Jiaying City have been complaining a few days ago that as the number of night mosquitoes continues to increase, night mosquitoes are everywhere. Even when sleeping, you can hear the buzzing sound of mosquitoes in the dark night, which is really unbearable. However, after the breeders’ union announced a formula for chemical repellent, and citizens followed it, they became much quieter. However, the number of night mosquitoes has not decreased, but has a tendency to increase. Ye Bai brought Lei Guang Shui Hui to the riverside. Due to the floods, the river water is still turbid, and dark night larvae appear in the river from time to time.
A heavy-duty truck carried a truck full of thunderbolts and dropped them into the river. Leiguang Shuihao plopped into the river, and soon there was a crackling sound of electricity in the river. These lightning water flies emit a strong golden light. The Dark Night Jie was no match for him at all. After being anesthetized by electricity, he bit his head off. This is how the lightning water hyacinth can quickly clean up the larvae in the dark night. Moreover, water hyacinths are very picky eaters, and they only eat the heads of night larvae. “Let’s go back to the laboratory.” Ye Bai wanted to know how the thunderfly evolved into the thunderfly. Does the Thunderbolt Waterfly have a special way to evolve? Ye Bai took out all the thunder-type treasures in the research institute. The most common ones are the crystal nuclei of thunder gallbladders and ancient lantern fish. “These two are water-type beasts, so they should be universal.” Ye Bai opened his eyes of insight, and sure enough, he discovered a hidden evolutionary route under the lightning water. 【Name: Lei Guang Shui Hao】 【Gender: Male】 【Attribute: Thunder/Water】 【Level: Level 1 and Level 5】 【Skill: Discharge (skilled): Release electric current to attack the opponent. Bite (skilled): Bite the opponent with a mouth full of sharp teeth. Chasing (entry): Swim quickly underwater to chase or attack the opponent. 】 Evolution route 1: Thunderfly. When the Thunderfly reaches the third level, it will naturally evolve into a Thunderfly. 】 [Evolution Route 2: Thunder Dragonfly, take Thunder Gallbladder and Ancient Lantern Fish's Crystal Core. Different ratios will have different evolutionary effects. 】 Ye Bai understood it as soon as he saw this prompt. This is a reminder to yourself that you need to conduct group tests on your own to hide the evolutionary route, and then find the best ratio of thunder bladders and ancient lantern fish crystal cores. If this is the case, it is almost the same as the blood poison moth experiment. If he could develop the evolutionary route of the Thunder Dragonfly, he would probably be highly praised. Ye Bai brought back five pairs of lightning water flies this time, making a total of ten. If the evolution fails, the Thunderfly should evolve into the Thunderfly.
Ye Bai took out ten large transparent tanks and filled them with clean water. Then he marked the lightning water flies and put them in them. He also wanted to compare whether experiments on lightning water hyacinths of different genders could achieve the same effect. For example, if thunder galls and ancient lantern fish crystal nuclei are fed in the same proportion to thunder galls of different genders, will the female evolve into a thunder dragonfly and the male evolve into a thunder dragonfly? Done, I got the Riwan badge.
