Su Yan sent the two of them to the roof and then went about her business.
First, she put the two little ones in the space. She and Su Qing replaced and reinforced the sewer mesh, cleaned and disinfected it, and turned on the indoor exhaust system.
Seeing two large bags of things in the living room, Su Yan remembered that the tuition fee that Lou Xue gave to Yang Jinghui was still there. She would talk to him about it another day.
After cleaning up 3201, Su Yan and Su Qing went to 3202 and found that it had not been captured.
"Aunt, please look after the house while I take care of the cockroaches outside the security door in the hallway."
"Okay, wait a minute, intercom."
Su Qing ran to the living room and got the intercom for Su Yan.
"Sister Yan, wow, I have cockroaches here. Great, they are so big, I can't kill them all..."
"Xianxian? You and Xiaoxuan should be careful not to get bitten. I'll get off the bus right away. Please open the door for me later."
Luo Wanning was in the infirmary, and it was unknown whether Uncle Zhang was at home. Su Yan took the insecticide and went downstairs, closing the corridor windows and spraying the pesticide all the way.
From the sounds, the residents downstairs were all fighting with their own cockroaches and no one cared to go up to the staircase. Fortunately, not every floor was infested with cockroaches.
It took Su Yan almost ten minutes to reach the 11th floor.
As soon as there was a knock on the door, Xianxian opened it.
"Sister Yan, there are so many, I can't finish them all."
The little girl's eyes were filled with tears, and she kept slapping the cockroaches on the ground with a broom. Xiaoxuan stood on the sofa in the living room, also crying and shaking her clothes, which seemed like she was performing a shaman dance.
"Don't be afraid, take this medicine and spray it on the cockroaches."
She gave a bottle to Xianxian, and Su Yan gave another bottle to Xiaoxuan, and then they looked for a place with a sewer.
"Sister Yan, there are so many in the kitchen."
"Okay, I'll spray the cockroaches to death."
Su Yan closed the open window in the kitchen, then sprayed a whole bottle of medicine and checked several rooms.
When Xianxian and Xiaoxuan saw Su Yan coming, they felt reassured, stopped crying, and started killing insects with pesticides.
Xiaoxuan was even more excited, "Sister Yan, Sister Xianxian, hahahaha, the ugly cockroach is upside down, die quickly, die quickly..."
"Why are you yelling? Be serious! Look at your trouser legs!" Xianxian sprayed medicine all over her silly brother.
"Ah!" Xiaoxuan looked down and saw a mutant cockroach crawling into his trouser leg. The child threw away the insecticide bottle and hugged the back of the sofa, kicking his legs desperately.
"It fell, the cockroach fell to the ground!"
"It hasn't fallen off. It's still on my leg. It hurts. Woo woo..."
After checking several rooms, Su Yan came out and heard Xiaoxuan crying loudly, and Xianxian was rolling up Xiaoxuan's trouser legs.
"What's wrong?"
"Sister Yan, Xiaoxuan said his legs hurt. A cockroach just crawled over his legs and he might have been bitten."
"Let me see." Su Yan saw that there was indeed a cut on Xiaoxuan's calf, which was already red and swollen. "Don't cry, just apply some medicine."
"Xianxian, will your mother come at noon? Where is Grandpa Zhang?"
"My mother couldn't come at noon, and Grandpa Zhang also said he wouldn't be home for lunch when he went out in the morning, so he asked Xiaoxuan and I to cook noodles."
The kitchen couldn't be cleaned, and Su Yan was worried about Xiaoxuan, so she just took them upstairs first.
