I was a rookie reporter in the 00s

In the small prison cell of the pharmaceutical factory, Zhang Wanqing, Fu Siyuan, and Li Wei sat together, their eyes scanning each other's faces, searching for the strength to persevere. The evidence had been destroyed, and their situation had become more difficult than ever.

"We must change our strategy," Zhang Wanqing said in a low but firm voice. "We can't just sit here and wait for death."

Fu Siyuan held Zhang Wanqing's hand tightly, his eyes revealing a hint of worry: "Wanqing, what are your plans?"

Zhang Wanqing took a deep breath and scanned the cell, searching for a possible escape opportunity. "Let's surrender first and get them to let us out. Once we're free, we'll find a way to re-investigate."

Li Wei nodded, his eyes gleaming with determination. "That's a good idea, but we must be careful not to let them see our true intentions."

The next day, a senior representative from the pharmaceutical company returned to the cell, a hint of smugness in his eyes. "What have you considered?" he asked, his voice tinged with sarcasm.

Zhang Wanqing raised her head, a hint of fatigue in her eyes: "We...we are willing to cooperate."

The senior representative's mouth curled up into a smug smile: "This is a wise choice."

Fu Siyuan and Li Wei clenched their fists, their hearts filled with anger, but they knew that now was not the time to resist. They had to be patient and wait for an opportunity.

Under the arrangement of the high-level representatives, Zhang Wanqing, Fu Siyuan, and Li Wei were released. They walked out of the pharmaceutical factory gate, the sun shining on their faces, but there was no joy in their hearts. They knew that this was only temporary freedom and they had to act quickly.

"We can't waste time," Zhang Wanqing said with a hint of urgency in her voice. "We must find new evidence as soon as possible."

Fu Siyuan began to collect relevant information about the pharmaceutical factory: "I will start with the internal system of the pharmaceutical factory to see if I can find some missed clues."

Li Wei began contacting his former colleagues, hoping they could provide some help: "We have to find some insiders who may know some information that we don't know."

Over the next few days, Zhang Wanqing, Fu Siyuan, and Li Wei began an intense reinvestigation, interviewing former employees of the pharmaceutical factory, collecting its financial records, and even sneaking into its laboratories, hoping to find any missed evidence.

Zhang Wanqing, Fu Siyuan and Li Wei sat in the corner of a small cafe. In front of them sat a former employee of the pharmaceutical factory. His hands were trembling as he held a cup of coffee, his eyes revealing fear and anxiety.

“I…I don’t know if I can help you,” the former employee’s voice was low and trembling, “but I don’t want to see any more children get hurt.”

Zhang Wanqing held his hand tightly, a look of determination in her eyes: "We guarantee your safety. We need to know the real situation inside the pharmaceutical factory."

The former employee took a deep breath and began to describe the unusual things he had seen while working at the pharmaceutical factory: "Some vaccine batches undergo special 'treatments' before leaving the factory. I don't know what they are, but I know it's not normal."

Fu Siyuan quickly wrote down this information, his brow furrowed, his mind filled with doubt. "Can you provide more details? For example, the batch numbers of these specially treated vaccines or the personnel involved?"

The former employee nodded and pulled out a crumpled piece of paper from his pocket with several vaccine batch numbers on it. "I wrote these down secretly. I don't know if they will be useful."

Although there are batches of problematic vaccines, there is no guarantee that the problematic vaccines will be found because the problematic vaccines are mixed with qualified vaccines and randomly injected into children. This has brought great difficulties to the investigation.

They have to visit each vaccinated child one by one to find those who have side effects from the problematic vaccine.

Fu Siyuan sat in front of his computer, the screen displaying the pharmaceutical company's financial records. His eyes were fixed on the screen, his fingers tapping rapidly on the keyboard, trying to find any anomalies in the flow of funds.

"Several large sums of money have been transferred to an unknown account," Fu Siyuan said with a hint of nervousness in his voice. "The flow of these funds coincides with the production time of the vaccine."

Li Wei stood behind him, his eyes revealing a hint of determination: "The flow of these funds may be the key to our exposing the crimes of the pharmaceutical company."

Fu Siyuan nodded. He continued digging and discovered that the funds ultimately ended up in a secret overseas account. "This account is connected to an international criminal organization," he said, his brow furrowed. "The pharmaceutical factory may be connected to a larger conspiracy."

"It could be money laundering, or there could be some kind of transaction. We don't know yet. I will let my brothers investigate secretly." Li Wei said.

Zhang Wanqing stood outside the pharmaceutical factory's laboratory, her eyes scanning the laboratory windows, searching for any missing evidence. She knew that the laboratory might be hiding the factory's secrets.

"We have to go in and take a look," Zhang Wanqing said in a firm and powerful voice. "Maybe there's evidence in the lab that we've missed."

Li Wei nodded and began to check the laboratory's security system, looking for possible loopholes. "There's a ventilation duct here that leads into the laboratory," he said in a low and powerful voice. "We can go in from here."

Fu Siyuan was responsible for monitoring the lab's security system to ensure their actions wouldn't be discovered. "I'll temporarily disable the security system," he said with a hint of nervousness in his voice, "but we have to be quick. I can't guarantee how long it will last."

Under Fu Siyuan's cover, Zhang Wanqing and Li Wei quietly entered the laboratory. The interior of the laboratory was dim and spacious, with various instruments and test tubes neatly arranged. In the center was a huge freezer, which stored rows of vaccine samples.

Zhang Wanqing's brow furrowed as she scanned the lab until she spotted a forgotten corner. There were some scattered documents and test tubes, seemingly left behind in a hurry.

"Something is wrong here," Zhang Wanqing's voice was filled with a hint of nervousness. She quickly picked up the documents and test tubes, hoping to find some clues.

After getting these clues, Zhang Wanqing and Li Wei did not stay for too long and hurried back.

After several days of hard work, Zhang Wanqing, Fu Siyuan, and Li Wei finally found some key evidence, including internal communication records of the pharmaceutical factory, vaccine production records, and some omitted laboratory reports.

"These records show that the pharmaceutical company deliberately added several experimental vaccines to approved vaccines during the production process. They then mixed these vaccines with approved vaccines and randomly injected them into children," said Zhang Wanqing, her voice tinged with anger. "They knew these vaccines would have side effects, but they chose to conceal them."

Fu Siyuan and Li Wei's expressions also became solemn. They knew that these evidences were enough to expose the crimes of the pharmaceutical factory.

"But there's one thing we forgot." Fu Siyuan suddenly thought of a very important question. "Since they are conducting experiments, it's impossible for them to inject the children with the problematic vaccine and then leave them alone. They will definitely visit these children and obtain relevant data so that they can continue their experiments. So, we can make a breakthrough here, find the return visitors, and obtain the experimental data. This data is enough to prove that they are conducting illegal human experiments. Moreover, we can also know what the purpose of their experiments is."

"Hey, brother, are you smarter than me, the great detective?" Li Wei said with a smile.

Fu Siyuan was also amused by him.

"Fu Siyuan, it's a pity that you don't become a policeman. You are even better than the great detective Li Wei." Zhang Wanqing also said.

The three of them hadn't laughed so hard in a long time. They temporarily put down their burdens and relaxed for a short time.
