Though James was usually strict with students, he rarely lost his temper. However, upon hearing the students' reluctance, he slapped the test paper on the desk and said in a cold, stern voice, "If none of you want to ask, then we'll let this go today. Just hope you don't regret it later."

James knew that, even though Yvette didn't want to reveal her identity as Siren now, it was only a matter of time before it was exposed. By then, it would be too late for these students to have any regrets.

Jay nodded and said to Yvette, "Let's not bother with the questions. Wouldn't it be better to discuss things with me?"

Yvette turned, rolled up her sleeves, exposing her slender wrist. Tapping the test paper with her fingertip, she looked up, her expression nonchalant. The test clearly hadn't affected her mood. Glancing around the room, she said, "Since we're betting, there should be stakes. What can you put up?"

Everyone was stunned. Suddenly, they remembered Ryan mentioning Yvette's one-night, $100 million win. They responded in unison, "We don't have any money."

Yvette crossed her legs, her expression indifferent, and glanced at Ryan, who stared at the floor. "Whatever you have, put it up," she said, her tone unchanged.

Spencer's face twitched as he said, "Ms. Zeller, this feels inappropriate. Isn't this gambling?"

Yvette nodded. "Yes, it is."

Everyone looked at James, wondering how he could possibly allow open gambling. To their surprise, he nodded. "Let's go with what Yvette said. If you have money, put it up. If not, I can lend you some. Just sign an IOU."

Jay's eyes widened in disbelief. He thought, Wow! This master's money-making methods are unconventional. Mr. Owens seems to have gone astray too.

Nearby, Marcus said, "I can lend too, at a lower interest rate than Mr. Owens. Feel free to come to me."

The twenty people from the outer lab gathered to discuss, occasionally glancing at the relaxed Yvette. Ryan stood silently to the side, his eyes lowered.

Ten minutes later, Spencer, the first to place a bet, stepped forward. "Ms. Zeller, since Mr. Owens has approved, we agree. We can only gather $15,000. Is that acceptable?"

Propping her chin on her hand, Yvette nodded slightly at the mention of $15,000. "That's fine," she replied crisply. "If I lose, I'll give you $150,000—ten times the amount."

Some felt a tinge of excitement. This money is too easy to win. Yvette must be a rich fool. What a missed opportunity!

With that, the bet was set. Spencer breathed a sigh of relief. "You can take as long as you want," he said. "We have experiments to run. Ms. Zeller, you can use the second room on the left and call us when you're done."

Yvette looked up, noticing the increasingly annoyed crowd. Narrowing her eyes, she replied casually, "No need. Twenty minutes will be enough, and I'll do it here."

Silence fell. The only sound was breathing. Jay and Marcus knew Yvette was Siren, a physics prodigy. But the test covered physics, biology, astronomy, and mathematics. Finishing in twenty minutes seemed incredible.

James said nothing, believing Yvette could do it. Ignoring the disbelief, Yvette casually picked up a pen. Her foot tapped lightly as a slight smile touched her lips. She began working, writing quickly, her pen barely pausing.

Except for James, Jay, and Marcus, the others could only see her scribbling. She glanced at the questions, seemingly needing no time to think. Doubtful glances were exchanged.

Someone whispered, "She's good at pretending. Is she even reading the questions?"

A petite girl agreed. "Who does she think she is? What is Mr. Owens thinking, asking her to be our teacher? We're all top science students. What makes her so special?"

A girl with glasses retorted, "Do you really think Mr. Owens is that clueless? If she wasn't capable, do you think he, Maxwell, or Mr. Decker would treat her this way?"

The whispering stopped. They thought that even if Yvette was talented, she couldn't finish twenty questions in twenty minutes, let alone correctly.

At the fifteen-minute mark, Yvette's writing slowed. Spencer guessed she'd reached his optics question, which had stumped him. Seeing her slow further, he sighed, expecting disappointment.

Only James, Jay, and Marcus saw that Yvette hadn't paused on any question. Two didn't even require calculations; she simply wrote down the answers. Is she even human? Her brain works at the speed of a computer. The three shared expressions of utter shock. Even Marcus felt the scene was surreal. People like her are truly on a different level. She is the true genius.

At the nineteen-minute mark, Yvette set down her pen, twirling it before replacing it. She looked up, raised an eyebrow, and said calmly, "All done."

Expressions of disbelief filled the room. They stared at the test paper, shocked and anxious.

James stood, cleared his throat, and said, "The test is done. For fairness, I'll project the answers on the big screen so we can all grade them together."

"Sounds good, Mr. Owens." "I agree, Mr. Owens." "That's a great idea."

Yvette checked her phone. A message from Jeremiah appeared: [I'm at the door, waiting for you. No rush.] She replied, "Okay," and stood.

Tilting her head, she said, "I'm leaving now. Jeremiah's here to pick me up."

James was surprised. "You don't want to stay for the results?"
