Zheng Tan remembered Papa Jiao telling him that newly bought bottles of medicine always came with a cotton ball that should be thrown away right after the bottle was opened.
The cotton ball was placed in the vials to prevent the medicine tablets from colliding together while being transported. It also absorbed moisture to prevent the drug from getting damp.
But if the cotton ball was kept in the bottle after the bottle was opened, it would continue to absorb moisture, which made it easier for the medicine to go bad.
Zheng Tan wasn't sure if the guy on the ground knew he had to take out the cotton ball. Intuition told him that he probably kept it inside to prevent the bottle from rattling when he moved.
He looked at the cotton ball in Wei Ling's hand. It was too large to have come with the original packaging. Judging from the half torn off label, the medicine was bought some time ago.
Not all medicines needed a cotton ball anyways, so Zheng Tan trusted his intuition.
Wei Ling looked into the bottle, then slapped the guy with the side of the blade again. "You've used this quite a few times already. Must have made quite some money."
"I don't ... don't understand what you are saying ..." The man tried to argue, "That 's just ... my own ... motion sickness meds."
"Do I look like I'm stupid?" Wei Ling stood up and kicked the man.
The guy curled up after the blow.
Wei Ling had noticed Zheng Tan's presence a while ago, so he didn't argue on with the man. He took three pills out and stuffed them into the man's mouth. "Come by again soon.
Just bring more money next time. 1000 yuan can't do shit. "
The guy got up immediately, ignoring the pain in his stomach. He didn't notice Zheng Tan by the stairs. It was dark in the stairwell and he was black cat.
It was normal that the guy didn't see him.
Wei Ling wasn't someone with upright morals either. Zheng Tan came to that conclusion.
Wei Ling could have brought the guy to the police, but he acted mostly based on his mood. He didn't want to trouble himself with going to the police so the thief got lucky this time.
Wei Ling was sitting on the side of his bed, stuffing his newly stolen 1000 yuan inside his own wallet when Zheng Tan stepped into his place.
The white plastic vial was placed on the bedside table, next to a glass of orange juice.
Seeing that Zheng Tan was eyeing the bottle, Wei Ling motioned him over. Zheng Tan jumped onto a chair.
Wei Ling still felt he was too far away so he dragged the chair by the bedside table.
Zheng Tan stayed put while he dragged the chair. He was too lazy to jump down.
"Did you see that?" Wei Ling pointed to the white vial and continued, "This thing really is motion sickness medication, but that idiot also used this to commit his crimes."
Wei Ling pointed to the half torn label, which said "One pill every time". The name of the drug was mostly torn off. Zheng Tan couldn't tell what it was.
"Most of the motion sickness drugs make people drowsy. If taken in large doses, it could cause headaches, severe drowsiness, orientation disorders and other adverse reactions.
It could even cause hallucinations and other mental symptoms. People are smart these days. They know purchasing sleeping pills will draw attention.
But people buy motion sickness meds all the time, and no one at the pharmacy would take special notice. They could also deny attempting to drug their victims if they were caught.
However, sometimes, motion sickness drugs can also be deadly. "
Wei Ling got up to pour away the cup of orange juice. It was laced with drugs. "You need to pay more attention in the future. Be careful of things given to you by strangers."
Wei Ling then told Zheng Tan about the types of drugs he needed to be cautious of.
He also mentioned some specific ingredient or contents that Zheng Tan should know, such as barbiturates, hyoscyamine and so on.
Medicine can save people but can also kill people. A large dosage of some meds can even harm a human being, let alone a cat.
Wei Ling bought some food from nearby, then left the apartment, with Zheng Tan by his side. Zheng Tan remembered to check as they were walking out.
The apple core Wei Ling tossed out was lying inside a trash can.
Was it a coincidence or was Wei Ling that good?
Wei Ling had bought a motorcycle. It was parked in the bike shed in the eastern quarters when he wasn't using it. After all, it would probably be stolen if left in front of his building.
It was safer leaving it in the quarters. The security guy knew Wei Ling and could help keep an eye on it.
Shortly after Zheng Tan and Wei Ling got home, Auntie Ling brought Jiao Yuan and Gu Youzi back.
Qu Xiangyang opened his door just when Auntie Ling was greeting Wei Ling. The three started chatting.
Auntie Ling had met Wei Ling once before and remembered him, but this was the first time Qu met the guy.
"We could sleep soundly now that we know you are here!" Qu Xiangyang said.
"Hey Qu, is that cat claw marks on your door?" Auntie Ling asked.
"Yeah, it is. I don't even know when it got there. Maybe Charcoal was letting out steam? Look how deep the scratch marks are. I didn't know Charcoal's claws were so sharp." Qu Xiangyang sighed.
"That's for sure. You need to sharpen your tools before you tackle a task. A cat needs to know it's a cat.
What can it do without sharp claws?" Wei Ling looked over at Zheng Tan, who was laying on the couch. "Am I right?"
Zheng Tan ignored them.
"Are you going to change your door? How about getting a steel one?" Auntie Ling joked.
"I'm not going to change the door. It I have claw marks on the door, mice wouldn't come by anymore, right?"
That night, Wei Ling heated some bath water and waited until the kids were bathed and in bed. He sat down at Papa Jiao's desk and started reading the material he had brought.
He had gotten permission from Papa Jiao to use his computer for some research. He had closed the door, so Zheng Tan had no way of finding out what the documents were about.
It seemed that he wouldn't get a chance to tell Wei Ling about the thing. Zheng Tan considered for a moment and decided to go to bed first.
He would figure out how to tell Wei Ling, then leave the rest till tomorrow.
