Grandma Gu hurriedly pulled Zhang Zian to the door of the office of the street office.
Zhang Zian was quite resistant. He did not want to face the hateful Director Yan again. He stood at the door and did not go in. He said, "Grandma Gu, if you have something to say, just say it. There is no need to go in with you. I still have things to do in the shop …"
"We are already here. What is the point of standing outside? Go in, go in! "
Grandma Gu took advantage of her seniority and did not listen to him at all. She forcibly pulled him into the office.
There was no change in the office. Director Yan was indeed there, but her expression was not very normal. She was slowly packing up her things with a sad face. It was not as simple as packing up things to get off work. After all, she had just started working. She was putting all her personal belongings on the desk and in the drawers into a storage box.
Grandma Gu gently tugged at him and whispered, "Alas! These days, you have to be careful with your words! Little Yan's work ability is not bad, but this is not good. Finally, trouble comes from the mouth … "
"What?" Zhang Zian did not understand.
Grandma Gu gave him a look and whispered, "It was that day. Weren't you there that day? Little Yan ran outside and stopped a telecommunications engineering vehicle to prevent the telecommunications workers from going to Donghua District to do construction work … The mistake appeared in a sentence she said at that time. She told them that she represented the public opinion of Donghua District. As a result, one of their employees was recording with his mobile phone. After he went back, he posted her words on the Internet, causing an uproar on the Internet … It seems that the netizens were all ridiculing her, saying that they were being represented again … Then … this morning, the leader told her to go through the resignation procedures … Tsk, what a pity. She is only a few years away from receiving her pension, so she has to watch her mouth. God knows when someone will record it … "
The office was not big. Even if Grandma Gu lowered her voice, Director Yan should be able to hear it. However, she was like an empty shell that had lost her soul. She no longer responded to others pointing at her. Even when she passed by Zhang Zian after packing up her things, she did not look at him. She just held the storage box and left.
When she stepped out of the office, Zhang Zian did not know if it was an illusion, but the other young civil servants seemed to be relieved.
It seemed that being in the same office with her was not a pleasant experience.
"Zhang Zian, don't worry about her. Tell me what you said the other day. I have to write it down quickly. The higher-ups have called for everyone to work together to fight against the insect disaster!" Grandma Gu pulled Zhang Zian to sit down, put on her reading glasses, and took out a small notebook.
"Cypermethrin," he replied. "Didn't someone check it on the Internet the other day?"
"Cough! That person asked for leave today! His computer has a password, so no one can open it and see the records! "Grandma Gu shook her head and sighed." What is the word for ester? "
Zhang Zian took the notebook and wrote the four words on it.
Grandma Gu looked at it and said, "Oh, it's these words …"
"Yes, after diluting it appropriately, you can put on protective clothing and a gas mask and spray it." He nodded.
"Then … what is considered an appropriate dilution?" Grandma Gu was cautious. Afraid of making a mistake, she kept asking.
"It should be in the manual."
"Oh …"
Zhang Zian felt that there was nothing else to say, so he decided to get up and leave.
"Wait, Zian, don't be in a hurry to leave." Grandma Gu pulled him back and said with a pleasant face, "If only I had listened to you that day, but it's too late to regret it now. The main person in charge has already … been fired, so Zian, don't hold any grudges in your heart."
It was impossible to say that Zhang Zian didn't have any grudges in his heart. He had kindly provided a way to prevent the insect disaster, but it had been thwarted for no reason.
However, as Grandma Gu said, the culprit who had obstructed this matter had been fired. It could be regarded as retribution for being too arrogant and domineering.
Moreover, the sooner the insect disaster was eliminated, the sooner his pet shop could operate normally. Otherwise, he would have to sit around and eat away his money.
"I know, Grandma Gu. I don't mind," he said.
"Good, that's good …" Grandma Gu smiled with satisfaction. "Zian, listening to you the other day, you seem to be very good at these caterpillars? Tsk, you make it sound so clear and logical. "
"I know a little." He didn't say too much.
Since he realized that the insect disaster might break out, he did check a lot of relevant information.
"Then … these caterpillars outside, where do they come from? What species are they? This … when the higher-ups ask us, we all don't know anything … "Grandma Gu smiled bitterly." Zian, if you know, you must tell Grandma Gu. "
Zhang Zian had already paid attention to it on the way here, so he immediately replied, "Grandma Gu, I didn't mean to hide it, but there are too many types of caterpillars outside. I can't tell you all in a short time … I can only say that near the street office, the most common caterpillars are the larvae of the oak procession moth. This kind of caterpillar caused a lot of trouble in London, England, and Belgium in 2018 and 2007. Each oak procession moth larva has 63000 poisonous hairs on its body. They are very poisonous, and the poisonous hairs will drift around with the wind. At that time, the Belgian government had to send 24 soldiers with flamethrowers to destroy them … "
Grandma Gu was stunned. She didn't expect the small caterpillars to be so powerful that foreign governments had to send armed soldiers to deal with them.
"What? So powerful? "
"Because the oak procession moth larvae have evolved a strong resistance, and the general pesticide has no effect on them." Zhang Zian nodded.
"Even that … cypermethrin doesn't work?" Grandma Gu asked.
"This … I don't know. Maybe we can try it." Zhang Zian was not sure. After all, only those who had tried it would have the right to speak, but he was inclined to not do so. Cypermethrin was not a recent invention. If it was useful, Belgium would not have to send armed soldiers.
May and June of every year was the larval period of the oak procession moth. After this period, they would emerge and become moths.
"What if it doesn't work?" Grandma Gu was worried.
Zhang Zian thought about it, wrote down a phone number, and handed it to her. "This is Professor Wei Kang from the Department of Biology at Binhai University. You can try to call him. Maybe there is a special pesticide in the research stage in the university laboratory, or you can try using biological control methods."
"Okay, okay! It makes sense! " Grandma Gu was enlightened and carefully put away the note. "I will explain it to the higher-ups, but I am old. If there is anything that I can't explain clearly, I have to ask you to report it to the higher-ups in person."
"I am duty-bound," Zhang Zian agreed.
