Chapter 150: Biological Mosquito Repellent Method

The flood lasted for three full days and nights, and only after the final wave of the flood peak had passed safely did the members of the Pet Beast Association, covered in mud, finally breathe a sigh of relief.

Large patches of yellow mud appeared everywhere the water had flooded.

The Pet Beast Association dispatched large Water-type Pet Beasts to thoroughly wash away the yellow mud.

After the flood, many things in the Breeding House could no longer be used.

A massive cleanup was required.

After a flood, a great plague is sure to follow; the Dark Night Mosquitoes have begun to breed.

If you go out now without proper protection, any exposed part of your body will inevitably be bitten by a Dark Night Mosquito, leaving a large welt.

How to guard against Dark Night Mosquitoes has become a difficult problem for the Breeder Association, a subordinate of the Pet Beast Association.

At this time, Zhang Lingxue asked Ye Bai to go over.

She was wearing a white dress and had rabbit ears on her head.

Two Thunder Rabbits were helping Zhang Lingxue organize data.

"Ye Bai, the Breeder Association has sent a request for help. After the flood, Dark Night Mosquitoes are rampant, and we need to pool our wisdom to find a solution."

"I am still organizing the data on Positive Electric Rabbits and Negative Electric Rabbits, so you go in my stead."

"I am an Honorary Elder of the Jiaying City Breeder Association; since they have come to ask for help, you should go on my behalf."

Zhang Lingxue had been organizing data late into the night recently, and with the time for the Inspector's on-site assessment drawing near, there was not much time left for her.

However, the matter with the Breeder Association was very urgent, so Zhang Lingxue could only let Ye Bai go in her place.

As a subordinate organization of the Pet Beast Association, the Breeder Association's office was located near the Pet Beast Association.

There was a five-story building here.

The first floor was the office lobby, and the second floor was a place for breeding Pet Beasts.

The third to fifth floors were where the members of the Breeder Association worked.

At this moment, the members of the Breeder Association were all crowded into the large conference room.

The President of the Breeder Association, Liu Chenggong, and the President of the Pet Beast Association, Wang Jinyin, were sitting side by side.

"Everyone, with the Dark Night Mosquitoes running rampant recently, we must effectively curb their numbers."

"Does anyone have any good ideas?"

Liu Chenggong was extremely clever, but there was a huge red welt on his bald head, which looked like it had been bitten by a Dark Night Mosquito at a glance.

From a distance, it looked as if he had grown a horn on his head.

Wang Jinyin thought through all the sad things he could remember to keep from laughing out loud.

"I think we can use a physical mosquito repellent method."

"Build a large-scale mosquito repellent device to reduce the number of Dark Night Mosquitoes."

Someone immediately made a suggestion.

Liu Chenggong glared at the person fiercely: "Do you think Dark Night Mosquitoes are ordinary mosquitoes? They are incomparably cunning."

"A single Dark Night Mosquito is the size of a fist; you can imagine how large a repellent device we would have to build."

Liu Chenggong rejected this proposal, and immediately someone else suggested whether chemical mosquito repellent methods could be used.

By spraying scents that Dark Night Mosquitoes dislike onto the body, the goal of chemical repulsion could be achieved.

Liu Chenggong thought for a moment, then shook his head: "No, Dark Night Mosquitoes are not ordinary mosquitoes, and if their population continues to multiply..."

"It is very likely that a mosquito plague will occur."

"By then, the entire Jiaying City will be rendered barren by the Dark Night Mosquitoes that blot out the sky."

"It is also easy for high-level Dark Night Mosquitoes to be born."

"We must think of a way to eradicate the Dark Night Mosquitoes at the root."

At this moment, Wang Jinyin saw that Ye Bai looked like he wanted to say something but was holding back.

"Ye Bai, why don't you share your insights?"

When everyone saw Wang Jinyin call on Ye Bai in public, they immediately began to whisper.

"What kind of insight could a wet-behind-the-ears kid like him have?"

"That's right, what is his background? A minor actually dares to attend our meeting."

"I remember we sent the invitations to prestigious Breeders; how could one have been sent to a minor?"

Everyone had an expression of schadenfreude; they did not think Ye Bai could say anything of value.

Ye Bai took the microphone and adjusted the sound: "I personally believe that we should adopt a two-pronged approach."

"Use chemical repulsion and biological repulsion simultaneously."

"Chemical repulsion can solve the personal problem of citizens being bitten by Dark Night Mosquitoes."

"And biological repulsion can solve the Dark Night Mosquito problem at the source."

Upon hearing Ye Bai's words, Liu Chenggong became interested: "Then how do you think biological repulsion should be done?"

"We have previously tried Exotic Beasts like Poison Dart Frogs and Power Frogs, but unfortunately, they don't seem to care for Dark Night Mosquitoes."

Ye Bai shook his head: "They are not the best choice."

"The best choice should be dragonfly-type Exotic Beasts."

"They are the natural nemesis of Dark Night Mosquitoes."

"According to statistics, a dragonfly can eat one thousand mosquitoes a day, while dragonfly larvae can eat three thousand mosquito larvae a day."

"We can completely solve the Dark Night Mosquito problem by following this direction."

However, at this moment, Liu Chenggong asked another question: "Ye Bai, I am very interested in the biological repulsion method, but there is one point: will we, in order to eliminate one pest, introduce dragonfly Exotic Beasts, only to have them run rampant and become a new invasive species?"

Ye Bai nodded: "I have also considered this issue."

"We can start from two aspects: first, screen for dragonfly Exotic Beasts that have poor reproductive ability but can eat Dark Night Mosquitoes; second, screen for large-sized dragonfly Exotic Beasts."

"Unlike the Dark Night Mosquitoes, Dragonfly Exotic Beasts are quite large in size, making them relatively easy for us to capture."

"Everyone can think of it this way: if Dragonfly Exotic Beasts and Dark Night Mosquitoes were sold separately in a Pet Beast shop, which do you think would have a higher price?"

Everyone replied one after another that it would be the Dragonfly Exotic Beasts.

Ye Bai shrugged his shoulders at this moment: "Doesn't that settle it?"

"Dragonfly Exotic Beasts have high value, and where there is value, there will be people to capture them."

"We can completely establish an industrial chain for Dragonfly Exotic Beasts; for one, it can increase job opportunities, and for another, we can increase fiscal revenue by selling Dragonfly Exotic Beasts."

"Think about it, everyone—would you still feel that Dragonfly Exotic Beasts would become an infestation?"

After hearing Ye Bai's explanation, everyone felt that what Ye Bai said made sense.

After all, Dark Night Mosquitoes are pests with no value, and they are only about the size of a fist.

Whereas Dragonfly Exotic Beasts are at least over a meter long, with wings as thin as cicada wings and hook-like Zhua similar to sickles; taking them out would be quite stylish.

Aren't these Dark Night Mosquitoes just natural feed for the Dragonfly Exotic Beasts?

Thinking of this, the minds of the crowd became active.

"Now I have another question: we have already discovered several hundred types of Dragonfly Exotic Beasts."

"How do we find the Dragonfly Exotic Beasts suitable for clearing out Dark Night Mosquitoes from this massive family?"

"We no longer have time for trial and error."

Liu Chenggong said with a stern face.

"Chairman Liu, we can operate like this: first conduct an investigation into the Dragonfly Exotic Beasts to see which types have a stylish appearance, large size, and also feed on Dark Night Mosquitoes."

"Then we can make an initial selection, and once we have selected five groups, we will conduct parallel experiments."

"We can carry out experiments along every riverbank; this way, we can screen for suitable Dragonfly Exotic Beasts while also prioritizing the clearing of a portion of the Dark Night Mosquitoes to inhibit their reproduction rate, so that we can then exhaust every means to completely expel the Dark Night Mosquitoes."

"By the way, the Dragonfly Exotic Beasts must have a good temperament, otherwise, as Chairman Liu said, they might truly become a troublesome invasive species."

Ye Bai's words received the approval of the crowd.

Now everyone looked at Ye Bai with curiosity; who exactly was this guy a disciple of? Things they felt were very difficult were solved by Ye Bai in an instant.

The behemoth that was the Breeder Association immediately sprang into action and began to operate around the clock.

Through comparison, the staff screened out the larvae—nymphs—of five types of Dragonfly Exotic Beasts.

By this time, Ye Bai had already become an honored guest of Liu Chenggong.

"Report, Chairman, we have already screened out the nymphs of five types of Dragonfly Exotic Beasts; here is their data."

Liu Chenggong's secretary, Ms. Zhang, placed the data on the table, but Liu Chenggong did not flip through it; instead, he handed the data to Ye Bai.

"Ye Bai, help this old man vet these."

Ye Bai opened the data and took a look.

These five types of Dragonfly Exotic Beast nymphs were as follows.

Flame Nymph: The nymph of the Flame Dragonfly, generally living in river water with higher temperatures; while still a nymph, the Flame Nymph is still of the Water attribute, but once it evolves into a Flame Dragonfly, it will become Fire + Wind attribute.

Thunder Light Nymph: The nymph of the Thunder Light Dragonfly; they generate high-voltage electricity within their bodies while in the nymph stage, and usually, where there are Thunder Light Nymphs, there will be no other aquatic life.

Brute Force Nymph: The nymph of the Brute Force Dragonfly, which is also the largest type of dragonfly-type Exotic Beast; while still a nymph, they are already half a meter long, and by the time they evolve into Brute Force Dragonflies, their wings alone are four meters long.

Breeze Nymph: The nymph of the Breeze Dragonfly; it is the smallest type of dragonfly-type Exotic Beast, and they are deeply loved by girls.

Grass Nymph: The nymph of the Grass Dragonfly; they have something similar to water grass on the top of their heads, and they possess the function of Purification of water quality.

Ye Bai saw the Thunder Light Nymph at a glance; according to the system's prompt, the Thunder Light Dragonfly was the most suitable Exotic Beast for clearing out Dark Night Mosquitoes.

"We must first exclude the Flame Nymph; this guy has a relatively explosive temperament and is not easy to control."

"Once they evolve into Flame Dragonflies, will they affect the fire safety of our Jiaying City?"

"The second one to remove, I think, is the Breeze Nymph; this guy's practicality is not high, and while its appearance is quite beautiful, it is of little use for our disaster management of Dark Night Mosquitoes."

"I think we can start experiments with the remaining three groups of dragonflies."

"We will divide the Jiaying River into three sections and release these three types of nymphs into them respectively."

"First, control the number of Dark Night Mosquito larvae at the source."

"After they evolve into dragonfly-type Exotic Beasts, we will then clear out the number of Dark Night Mosquitoes, how about that?"

Ye Bai suggested to Chairman Liu and Chairman Wang.

"I have no issues."

Chairman Wang and Chairman Liu both nodded one after another.

"Everything shall be executed according to your plan."

The citizens of Jiaying City had been complaining for the past few days; as the number of Dark Night Mosquitoes continued to rise, Dark Night Mosquitoes were everywhere.

Even when sleeping, one could hear the buzzing sound of Dark Night Mosquitoes; it was truly unbearable.

However, after the Breeder Association published a chemical mosquito repellent formula, the citizens followed it, and it was indeed much quieter.

But the number of Dark Night Mosquitoes did not decrease; instead, there was a faint trend of them increasing.

Ye Bai brought the Thunder Light Nymphs to the riverside.

Due to the flooding, the river water was still muddy, and Dark Night Mosquito larvae could be seen in the river from time to time.

A heavy truck loaded with a full load of Thunder Light Nymphs was released into the river water.

The Thunder Light Nymphs splashed into the river water, and soon, the sound of crackling electricity came from the river.

These Thunder Light Nymphs radiated a strong golden light from their bodies.

The Dark Night Mosquito larvae were no match at all; after being paralyzed by the electricity, their heads were bitten off directly.

This was the means by which the Thunder Light Nymphs could quickly clear out the Dark Night Mosquito larvae.

Moreover, nymphs are a very picky type of Exotic Beast; they only eat the heads of the Dark Night Mosquito larvae.

"Let's go, we're heading back to the Laboratory."

Ye Bai wanted to understand how the Thunder Light Water Nymph evolves into a Thunder Light Dragonfly.

He wondered if the Thunder Light Water Nymph had a special evolutionary method.

Ye Bai took out all the lightning-type treasures in the Research Institute.

Among them, the most numerous were Thunder Galls and the crystal cores of Ancient Lantern Fish.

"These are both water-type Exotic Beasts, so they should be compatible, right?"

Ye Bai activated his Insight Eye, and sure enough, a hidden evolutionary path appeared beneath the Thunder Light Water Nymph.

【Name: Thunder Light Water Nymph】

【Gender: Male】

【Attribute: Lightning/Water】

【Level: Tier 1, Level 5】

【Skills: Discharge (Proficient): Releases an electric current to attack the opponent.

Bite (Proficient): Bites the opponent with a mouth full of sharp teeth.

Pursuit (Beginner): Swims rapidly underwater to pursue or attack the opponent.】

【Evolutionary Path 1: Thunder Light Dragonfly, the Thunder Light Water Nymph naturally evolves into a Thunder Light Dragonfly upon reaching Tier 3.】

【Evolutionary Path 2: Thunderous Dragonfly, consume Thunder Galls and the crystal cores of Ancient Lantern Fish; different ratios will result in different evolutionary effects.】

Once Ye Bai saw this prompt, he understood.

This was prompting him that the hidden evolutionary path required him to conduct group tests to find the optimal ratio of Thunder Galls to Ancient Lantern Fish crystal cores.

If that was the case, it would be similar to the experiments with the Blood Poison Moth.

If he could successfully develop the evolutionary path for the Thunderous Dragonfly, he would likely receive an extremely high evaluation.

Ye Bai had brought back five pairs of Thunder Light Water Nymphs this time, totaling ten in all.

If the evolution failed, the Thunder Light Water Nymph would likely just evolve into a Thunder Light Dragonfly.

Ye Bai took out ten large transparent water tanks, filled them with fresh water, marked the Thunder Light Water Nymphs, and placed them inside.

He also needed to compare whether experimenting on Thunder Light Water Nymphs of different genders could achieve the same effect.

For example, if he fed Thunder Light Water Nymphs of different genders the same ratio of Thunder Galls and Ancient Lantern Fish crystal cores, would the females evolve into Thunder Light Dragonflies while the males evolved into Thunderous Dragonflies?

Done, the Ten Thousand Word Badge is in hand.
