Abandoned daughter takes charge of the family, so rich that even the best people can't envy

After learning that the plague soldiers' disease was malaria, she thought of the holy water of the Saint of Southern Xinjiang, which might be the insecticide.

They often spray around the village to kill mosquitoes. Without the spread of mosquitoes, people in the village will naturally avoid the spread of malaria.

She also questioned the local soldiers and confirmed that the miasma they were talking about was caused by swarms of mosquitoes.

A large number of mosquitoes carrying malaria parasites gather together and fly, looking like a dark cloud of gas from a distance. When people and animals are bitten by them, they will be infected with malaria.

This is also the reason why Xiao Kuishan called poison barrier "poisonous wind".

When it comes to making insecticides, the first thing Song Jinxiu thinks of is pyrethrum and Central and Southern fishing vine.

Pyrethrum contains a substance that is highly toxic to mosquitoes, which will die after contact. It is a common insecticide, but it is very low in toxicity to the human body. Therefore, Song Jinxiu thinks it is the preferred plant for making insecticides.

The Central and Southern fish vine can also detoxify and kill insects.

The most important thing is that these two plants are very common in the south, and like Artemisia annua, they are everywhere in the mountains.

At this time, Su Chuan came to report: "Fang Ziyu and Poison Lady are here."

After his young disciple left a letter and ran away, Fang Ziyu was worried about her, so he knocked out Song Sanzhu, who was crying and trying to follow him, and chased her to the border with Du Niangzi.

"Greetings, Junior Grandmaster." The two of them performed the sect's grand ceremony.

Looking at the two exhausted people, Song Jinxiu quickly gestured for them to sit down and talk.

"You've worked hard along the way."

Glancing over, Song Jinxiu couldn't help but laugh when she saw her sister bending over and quietly retreating. She said in a deep voice, "Jinfang, why don't you come over to meet your master and master's wife? Why are you hiding so far away?"

Song Jinfang's body froze for a moment, then she smiled in surprise and trotted over: "Hey, Master, Master's Wife, when did you get here?"

That expression and that action are so fake.

Poison Lady said helplessly, "You are so naughty. If you want to come to Southern Xinjiang, at least let your nun accompany you. Don't you know how worried everyone at home is?"

Song Jinfang held her hand, grinning smugly, but secretly looking at the master.

Fang Ziyu said sullenly, "If there's a next time..."

Song Jinfang quickly said, "There won't be a next time, Master, don't worry, there won't be a next time."

Fang Ziyu was helpless. She was young and liked to play. She took in a little apprentice but didn't know how to teach her. She just took her out to play all day long.

Fortunately, this disciple was smart and learned things quickly. Later, with the guidance of his master Xuan Zhenzi, this disciple even surpassed his master in some aspects.

So he could only try to act stern to calm her down.

And her sister is the junior master.

It's strange to say, he knew the little master the earliest, and he didn't think she was that powerful at first, but he didn't know when it started, but every time he saw the little master, he always felt like he couldn't look her in the eye.

Just like this time, he was so angry that he wanted to scold his disciple, but he didn't dare to speak loudly in front of the young master.

Seeing her sister, her master and her apprentice having so much fun together, Song Jinxiu missed her brothers even more.

They had been there for seven or eight days, but there was still no news of their brother. The treasure-hunting Rat Junjun and his companions who went to the 18th Route Army to look for Song Chunsheng were blocked by a sudden mountain flood.

This made Song Jinxiu a little uneasy.

"If you take a detour, how long will it take you to reach the 18th Route Army?" Song Jinxiu and Junjun communicated with each other through their spiritual consciousness.

"We originally asked a local, but when they heard our accent wasn't local, they gave us the wrong directions. They were planning to arrest us and question us again."

The terrain here is complex and the locals are very hostile to outsiders. If you want to go to the 18th Route Army, it is better to find a scout who is familiar with the road to lead the way.

"Su Chuan, go ask General Xiao if there are any scouts familiar with the 18th Route Army's route."

Su Chuan asked, "Master, do you want to go to the Eighteenth Route Army to see the young master?"

Song Jinxiu nodded, and Su Chuan took the order and left.

Song Jinfang asked excitedly, "Sister, is there any news about my brother and the others?"

Song Jinxiu shook her head. "There was a flash flood over there. Fifteen, Sixteen, and Seventeen were stopped halfway. I haven't been able to contact my brother and the others yet. I plan to go there myself."

"Then I'll go with you." Song Jinfang said quickly.

She had wanted to go find her brother a long time ago, but her sister wouldn't let her, saying it was easy to get lost in the dense forests and mountains, and she was worried about her going. She knew her sister came to southern Xinjiang on a mission, so she stayed by her sister's side to avoid distracting her.

Moreover, she also likes being able to fight by her sister's side, swinging the Green Dragon Crescent Blade, and completely letting herself go.

Song Jinxiu glanced at the Poison Lady and said, "I'm only going with the thirty-six guards this time. It just so happens that the Poison Lady is here, and I have a mission for you."

As soon as they heard that there was a mission, Song Jinfang and Du Niangzi looked at her seriously, waiting for her to give orders.

Song Jinxiu talked about the pesticide.

When Poison Lady heard this, she smiled and said, "Don't worry, Young Master, I'll take care of the insecticide."

Isn't it just killing mosquitoes and insects? This is not a difficult task for her poisonous wife.

Song Jinxiu nodded and said, "Okay, I trust your ability, but the insecticide cannot be highly toxic to avoid causing harm to humans and animals after spraying."

She pointed at pyrethrum and said, "This pyrethrum is the best choice. It is highly toxic and will kill mosquitoes instantly, but it is not fatal to humans."

Poison Lady nodded: "Master Nephew Sun understands what Master Junior meant."

The words "master's nephew's grandson" made Song Jinxiu's mouth twitch.

"Well, the Saint of Southern Xinjiang has a kind of holy water. If you have the chance, you can take a look at it." Song Jinxiu talked about the holy water again.

Poison Lady suddenly laughed.

"Little Grandmaster, the holy water of the Southern Border Saint was passed down to her by my master, Guigu Yu."

Song Jinxiu couldn't help but show joy and asked, "Oh? Then how did it end up in the hands of the Saint of Southern Border?"

Poison Lady's eyes flickered, and she seemed to be hesitant to speak.

Song Jinxiu glanced at her and said, "Forget it if it's inconvenient to tell me, do you have the formula for this holy water?

Poison Lady nodded: "It doesn't have any recipe, it's just the excrement of the Gu King..."

Song Jinxiu understood immediately.

The holy water of the Saint of Southern Xinjiang is actually the feces of the natal Gu she raised.

Indeed, the Southern Border Saint's natal Gu is the king of all Gu, the king of poisonous insects. Wherever its excrement is scattered is equivalent to its territory. Because these excrement contain a scent that can convey information, some snakes, insects, rats and ants naturally dare not approach.

Without mosquitoes that can spread malaria, the villagers will naturally not get malaria.

The snake Gu of the Southern Border Saint evolved into the Dragon Gu, which has been completely absorbed by the treasure-hunting rat Junjun, so the Gu King's feces can no longer be relied upon.

Song Jinxiu thought: I wonder if the feces of the treasure-hunting rat has this effect?

Song Jinxiu said helplessly: "We don't have the Gu King's feces, so please use pyrethrum to extract it."

Poison Lady smiled in an ambiguous manner and lowered her voice, "Well, Junior Grandmaster, if you want to use the Gu King's excrement, our sect can provide as much as you want."

Song Jinxiu blinked. "What do you mean? Does the Xuantian Sect also raise Gu?"

Fang Ziyu suddenly said: "My grandmother is the saint of the previous predecessor, and her black dragon is the natal Gu."

Song Jinxiu: ...
