Lin Guaiji was still looking at Mo Shuwan. When Mo Shuwan finally met his gaze, he suddenly curled the corner of his lips at her.

It's as if to say, "I've already found out, and there's no point in you trying to hide it now."

"Number 11, number 5."

The captain of 204 was sitting in seat number eleven. He was extremely arrogant from the moment he met Mo Shuwan and the others. He also had a very arrogant name—Ao Tian.

"Gentlemen, there are only six hours left until the end of this test. We've been playing this game for sixteen minutes now, and neither of us can win. We're just wasting time." Ao Tian's words were unusually calm this time. He didn't get angry or discriminate against anyone.

“Since there’s no penalty, why don’t we all peacefully win the number of rounds that will earn us the reward? Nobody will lose out,” Ao Tian said. “How about I go first?”

His words had just used up his speaking time, and looking at the unresponsive passengers, the calm expression on his face finally cracked. "Hmph, it seems you're not only incompetent but also incredibly stupid."

He randomly chose someone to exchange cards with, then sat back down with a cold snort, his eyes as dark as ink.

Zhou Quansheng, whom he had chosen, looked at the cards and said, "Not dealing with you doesn't mean I'm incapable. The thing I hate most is being insulted. Do you want to try and see the consequences of insulting me?"

Zhou Quansheng actually has a baby face and is often overlooked. This time, he didn't even look up at Ao Tian, ​​but the threatening meaning in his words was already very clear.

Ao Tian's face grew even more grim. He knew from the moment he first met the people from 504 that they were not to be trifled with. He wasn't afraid of Zhou Quansheng alone, but—

Thinking of the descriptions of sinners he had seen before, Ao Tian suppressed his anger, unwilling to provoke a team containing sinners, as it would do him no good.

Ao Tian quieted down, and Zhou Quansheng didn't cause any more trouble. He looked at the cards in his hand and narrowed his eyes.

I only need two more cards to collect all ten of my own portrait cards. Where are the last two?

While most passengers were trying to prevent Mo Shuwan from getting a chance to switch cards, Zhou Quansheng had quietly collected eight cards featuring his own image. After a moment of contemplation, he finally chose card number six from Mo Shuwan's hand.

When the cards in his hand were exchanged, a smile flashed across Zhou Quansheng's eyes.

The opportunity to switch cards has returned to Mo Shuwan's hands. Wen Zuo wanted to remind her, but after thinking about how she had deliberately chosen other people's cards earlier, he desperately suppressed the urge to remind her. He sent a message, but Shuwan refused to listen in order not to expose him, and he himself could not continue to reveal any flaws.

Mo Shuwan breathed a sigh of relief when she didn't hear Wen Zuo speak.

More than twenty minutes have passed since the game started, and it seems that everyone can only rely on luck. However, Wen Zuo's hint just now gave Mo Shuwan a different idea. She did not believe that the game rules would have such a big loophole, allowing Wen Zuo and the others to see the passengers' cards directly.

The only possibility is that Wen Zuo figured out the pattern himself before telling her.

So what exactly is the pattern?

Since she had no clue what to do at the moment, Mo Shuwan didn't hesitate any longer and handed over the opportunity to switch cards.

After exchanging cards five or six times, Zhou Quansheng smiled and placed the card with his own image on the table, saying, "I won."

His ten cards vanished from the table, and Zhou Quansheng's chair was moved back slightly, clearly indicating that he was temporarily withdrawing from the game, while the game would continue.

Mo Shuwan leaned back in her chair, tilting her head slightly to look at Zhou Quansheng, her brows furrowed gently.

She quickly turned around and looked at everyone in 504. Fortunately, the passengers didn't choose her much, which allowed her to concentrate on observing their reactions. In the end, she actually discovered some clues.

Each time the players in group 504 exchanged cards, they would lightly tap their fingers on the table a few times, the number varying from person to person. Besides making no sound, their hands were not entirely on the table, making it difficult for others to notice.

Tap your index finger once to indicate card number two, tap twice...

Mo Shuwan turned her head to look at the passenger sitting very close to her, number three. Sure enough, the passenger who had chosen her had also chosen number two.

One tap with your thumb indicates card number 5, two taps indicate card number 17, three taps indicate card number 7, four taps indicate card number 26...

Mo Shuwan's gaze followed each passenger who changed their license plate on 504. She quickly jotted down the clues she had discovered in her mind, and saw that the opportunity to change the license plate had fallen into Su Xuan's hands.

"Number 35, number 9."

Lin Guaiji frowned and looked at Su Xuan. Su Xuan smiled at him, spread the cards on the table, leaned back, and slumped into the chair.

He tapped his little finger once, selecting seat number nine; he tapped his ring finger once more, selecting seat number thirty-five…

Mo Shuwan refrained from looking at Su Xuan. She was grateful that he was willing to help her in this time of need and wouldn't do anything that might cause him trouble. However... she noticed Lin Guaiji's furrowed brows out of the corner of her eye and couldn't help but sigh.

The captain of room 504 probably already figured out that Su Xuan was sending him a message, otherwise he would have won as soon as he finished exchanging the last card, and there would have been no need for him to deliberately reveal the code.

After exchanging cards more than sixty times, Lin Guaiji, the captain of 504, won and moved to the back of the chair. Ao Tian from 204 also won once. With five spots available, there is now only one spot left.

Mo Shuwan took a deep breath and quickly went through the clues she had just observed in her mind. The code for 204 used methods such as touching the ear and hair, which were very subtle and involved many small movements. It was impossible to remember them all.

Therefore, the next card swap will also depend on a certain amount of luck.

For my own sake, and for the sake of the moderates, we must win!

The opportunity to exchange cards fell to Liu Dongcheng. He glanced at Mo Shuwan and saw her nod slightly, so he exchanged cards with her.

Mo Shuwan held the cards, head down, quickly recalling the clues from earlier.

The passenger in seat number three has a number two card that is fixed to one of the people in seat 504. Even if the card is changed, the person in seat number two will always be one of their own. The passenger in seat number thirty-five has a number nine card that is fixed to Su Xuan. If the person in seat three changes, the seat will only be reserved for their own people.

During those dozens of card exchanges, none of their secret codes changed. Each person had their own unique code, and tapping different fingers a different number of times represented different people and different cards.
