At midnight, the Anding Division was still brightly lit.

Given his impulsiveness last time, Li Nan didn't dare go into the lab to check on Qin Wen's results again, and could only chat with Ma Jie and the others in the office.

Li Na's investigation has concluded, and the consumption records of the poisoned individuals on that day have been analyzed.

Aside from milk tea, there's nothing else in common; it's just a variety of eating and shopping experiences.

Including Xiong Sifu, everyone in the Anding Division generally believed that this was just a large-scale mass poisoning incident.

Now, we just need to wait for Qin Wen's final result so that we can define the nature of this incident.

Over the past few days, Qin Wen and her team from the Trace Investigation Department have tested all the suspicious items they brought from the pedestrian street.

All results were negative; everything was normal. Aside from identifying a few businesses with food safety issues, there was absolutely no connection to food poisoning.

Of course, food safety issues are no longer under the jurisdiction of the Stability and Safety Administration; the rest can be left to the food safety department.

Regarding the oranges and tea, Qin Wen and others traced the source all the way back to the red orange planting base in Yinghuadu. Apart from the new fertilizer DNs520 (donyne agate color enhancer) that was only used last year, there were no other abnormalities.

This new type of fertilizer is a legal fertilizer permitted by the state and has been used for decades. However, it was previously mainly used on ornamental plants such as roses, but last year it was discovered that it is also very effective in the cultivation of red oranges.

Although cherry blossom red oranges are now one of the specialties of Tanhua City, they used to sell poorly and were jokingly called gray-white bitter oranges.

Decades ago, the oranges of Tanhua City didn't have a specific name; they were simply grown and sold haphazardly by farmers in a rough-and-ready manner.

This orange is red inside, and the taste is so-so, slightly bitter. The orange peel is pink and white, which doesn't make it as visually appealing as other varieties, hence the name "grayish-white bitter orange."

Around 2000, a new order came to Sakura, and based on the color of the orange, it was named Sakura Red Orange. With years of experience in growing it, the orange became more and more delicious.

Afterwards, thanks to Du Ling's efforts and the strong promotion by the government, in recent years, cherry blossom red oranges, a fruit that was almost ignored locally, have gradually come into the public eye. Last year, they even developed a red orange wine called "Ephemeral Romance".

The use of this new type of fertilizer can be considered another leap forward for the cherry blossom red orange. With the use of fertilizer, the pinkish-white peel has become more vibrant and juicy, and the taste has been further optimized, with the bitterness reduced and a unique aroma added to the delicious flavor.

Since last year, sales of Sakura Red Orange have exploded, and prices have also increased by nearly 30%!

Qin Wen carefully studied the fertilizer DNs520. Apart from the flavor enhancer, it was no different from other fertilizers, except for the mixing ratio of nitrogen, phosphorus and potassium.

Experiments have shown that this flavor enhancer has no relation to the ricin poisoning.

The only relevant fact is that they share some of the same chemical elements, but that doesn't prove anything.

Most things in the world are composed of basic elements such as C, H, O, N, P, S, K, etc., so this alone is not convincing.

There's really nothing suspicious about the cloud and mist tea in the milk tea recipe.

Yunmeng Yunwu Tea is a native mountain tea of ​​Yunmeng County, and it has no reputation in the county, let alone being compared with the top ten famous teas.

The milk tea shop owner probably only bought these ordinary, cheap tea leaves from the tea market because he liked the name.

Tea merchants, perhaps to increase the selling price, add a common flavoring agent, AFX-320D alpha rosemary, to their tea. While this practice may be considered deceiving consumers, it's common practice nowadays, so there's not much to say about it.

This flavor enhancer sounds fancy, but it's actually just a mixture of several common tea flavor enhancers; there's nothing special about it.

Based on the above evidence, this should just be a serious case of mass poisoning with no identifiable source, right?

That's what everyone thinks!

...

"Ring ring ring"

Just as everyone in the An Ding Division was still working hard by lamplight, Gao Siming's phone rang. He glanced at the screen and smiled.

"Sis, why did you suddenly decide to call me at this time?"

"Dog Egg, you're probably still awake, right? Have you seen the news these past two days?" Gao Zimin on the other end of the phone was very anxious. She had been busy in the orchard for the past few days and had just finished today. She took a moment to play on her phone and only then did she learn that such a big thing had happened in Tanhua City.

Every time Gao Siming heard his older sister call him "Dog Egg," he always felt that it belonged to someone else, to the little kid in his heart. But his sister just wouldn't change her ways; she had been calling him "Dog Egg" since he was seven years old.

Every time I ask my sister why she calls her that, she always retorts, "Really? You've forgotten your own name again?"

Over time, Gao Siming's resistance proved fruitless, so he eventually gave in. Fortunately, his sister was very sensible; when outsiders were present, she only called him Ah Ming and never Gou Dan.

"Sister, are you talking about the mass poisoning incident?"

"Dog Egg, tell me the truth, could this be related to the fertilizer we're using?"

"Sister, how could that be? We only used a little flavor enhancer. The whole country allows it to be sold, and it's even safe to eat as fertilizer. How could it cause this? Besides, so many people in the village are using it now, and it's fine!"
