But just to be on the safe side, Han Linlin didn't want to reveal the serial number of the counterfeit product. She said matter-of-factly, "Do I, Han Linlin, need to care about such details when buying things?"

"The pen is in your hand, you can take a look." Qiao Xi smiled and gestured to her again.

Han Linlin's gaze was immediately drawn to the serial number on the pen, a string of numbers consisting of the three Arabic numerals '001'.

This isn't hers!

The serial number of her counterfeit product was clearly '055', so how did it become '001'?

Upon closer inspection, she noticed that this pen seemed somewhat different from hers. The difference wasn't immediately apparent, but upon closer inspection, the handwriting on this pen appeared to be clearer.

What happened?

Han Linlin unconsciously looked at Zhu Wenli, who was puzzled by her questioning gaze.

If Zhu Wenli didn't switch the items halfway through, then why was this pen with the serial number '001' in Qiao Xi's bag?

Moreover, with her discerning eye after examining so many genuine Jinghua Shijia products, she believed this pen must be authentic!

Qiao Xi knew she had discovered the problem, so she deliberately asked loudly, "The pen's serial number is 001, right?"

Before he finished speaking, the class erupted in an uproar.

Anyone interested in the products released by Jinghua Shijia this time knows what the number '001' represents.

Although it's supposed to be a benefit for members, how many members can actually snag the number '001'?

The students couldn't sit still and crowded around to look at the pen's serial number. After seeing it, they all looked at Han Linlin with admiration. Seeing this, Han Linlin didn't care about anything else and said loudly, "Of course I know the serial number of my pen. You don't need to tell me."

Enjoying the admiring, envious, and jealous looks from her classmates, Han Linlin had completely forgotten about her fake product.

Qiao Xi suddenly poured cold water on her, saying, "But I bought this pen."

Upon hearing this, everyone cast disdainful and mocking glances at her. Just as Qiao Xi had guessed, no one would believe her. After hearing her words, they all sighed and then cursed.

"Qiao Xi, you dare to insult her?!" Someone immediately led the way in verbally abusing her.

Others joined in the cursing, saying, "You stole someone else's things and claimed them as your own? How can you be so shameless?"

"Why don't you take a good look in the mirror? How do you think you can buy a limited edition fountain pen from Jinghua Shijia, number '001'?"

"Don't even mention 001, you can't buy even 099."

"I think you're overestimating her. In my opinion, the things that the Jinghua family has are beyond her reach."

"That's right."

In an instant, almost the entire class began to denounce her, except for Lu Mingxuan.

He was the only one in the know, but even so, he would never speak up for Qiao Xi; he would only stand by and watch.

Qiao Xi didn't expect him to testify for her. She calmly took out an invoice from her bag and showed it to them without hesitation, "This is my purchase receipt. It has my membership card and the corresponding purchase number on it."

"Heh." Han Linlin sneered and mocked when she saw the invoice. "You even forged an invoice."

Then someone else criticized her, saying, "Qiao Xi, do you think we're fools? You can tell at a glance whether the invoice is real or fake."

"You can verify its authenticity now." Qiao Xi adopted a posture of letting them check as they pleased, letting them do whatever they wanted. If some people were dissatisfied and tore it up, there were still records online. It all depended on how guilty she was.

However, no one seemed interested in verifying its authenticity, as they all assumed it was fake.

Just then, a cynical voice came from behind them, "I'll do it."

Chu Junze strolled over leisurely, and the onlookers unconsciously made way for him. He was the eldest young master of the Chu family, handsome and with a bad temper, which made many girls shy away from him.

Han Linlin had once been attracted to him, but he rejected her ruthlessly, unlike Lu Mingxuan who half-heartedly pursued her, making it seem to outsiders that he was rejecting Han Linlin, but in reality, he was giving her a chance.

Chu Junze glanced coldly at Qiao Xi before looking at the invoice and said with certainty, "The invoice is genuine."

This conclusion immediately aroused everyone's suspicion. "Young Master Chu, you can't be mistaken, can you?"

Chu Junze immediately shot a fierce glare at the person who had raised the question, and said in a warning tone, "I'm a VIP member of the Jinghua Family, how could I be mistaken?"

Normally, as long as Chu Junze speaks, even if it's false, it can be presented as true, and no one dares to question it. But in this matter, they seem unwilling to compromise.

Qiao Xi was also surprised that Chu Junze would help her, as they had no connection in their previous life.

“That’s impossible.” The voices of doubt arose again.

"Even if Qiao Xi is a member of the Jinghua Family, there is absolutely no way she could buy this pen."

Han Linlin retorted defiantly, "Young Master Chu, the technology for forging invoices is quite sophisticated these days. You'd better be careful."

Chu Junze sneered and gestured to her, saying, "You said the pen is yours, so let us see your invoice."

These words seemed to remind the students who were watching the commotion that they also wanted to see Han Linlin's invoice, not because they suspected her, but because they wanted her to deliver a fatal blow to Qiao Xi.

Han Linlin's throat tightened involuntarily, and she lied without thinking, saying, "I don't know where I put it."

"Give me a bottle of water." Chu Junze casually held out his hand, and his underling immediately handed him the water.

In front of everyone, he unscrewed the bottle cap, poured a few drops of water into the upper left corner of the invoice, and said as he poured, "As long as it is an invoice from Jinghua Shijia, there will be a mark in the top corner, which is the Jinghua Shijia logo. It will appear when it comes into contact with water."

"Like this." Soon the logo appeared in the upper left corner.

Before seeing this mark, Chu Junze couldn't be sure if the invoice was real. He was just very curious that this woman, who had no power or background and ranked last in the entire department, would have the audacity to go against Han Linlin.

Moreover, he remained calm and unhurried throughout.

With the emergence of the marker, many people should remember this method of verifying the authenticity of the publication, because Jinghua Shijia once announced this method to the public.

The truth is already clear. Chu Junze added one last thing: "If you still have any questions, you can directly contact Jinghua Shijia's after-sales service for verification."

Anyone familiar with this marking knows that invoices with this marking cannot be forged, so it's immediately clear who owns this pen.

Everyone immediately turned to Han Linlin with questioning looks. "What exactly is going on?"
