Seeing her ask the crucial question, it seemed she understood Tang Sili even better than him. Ou Yanan glanced at her face and hesitated a bit.

Tang Sili is very difficult to deal with. This is because Tang Sili hides himself so deeply. Reflecting on the time Ou Yanan spent with Tang Sili, he mostly followed the path laid out by Tang Sili. Maybe Tang Sili never gave him any direct orders, but in fact, Tang Sili excelled at using psychological tactics to guide him to act according to plan.

Can Zhao Mengjin find a way to break through such a Tang Sili?

Ou Yanan wasn’t sure. But he had no choice. He couldn’t share his concerns with Xiao Yebai or Gu Nuan. Because that would alert the enemy.

"Go ahead and tell me." Zhao Mengjin said, "I’ll weigh the pros and cons. Don’t worry, at least I won’t expose you."

Ou Yanan forced a smile, "Once I tell you, he’ll definitely guess it was me who told you."

"Why?"

"Because these aren’t things a doctor would notice. And, I’m his student. He knows exactly what my level is and where my focus lies."

"Then why not ask him directly?"

"Because I can’t get anything out of him," Ou Yanan admitted, acknowledging that in psychological tactics, he was no match for Tang Sili, "His medical knowledge is far superior to mine. What I can guess is only the tip of the iceberg of what he knows."

Perhaps, that person, like Tang Sili, already knows something. But, like Tang Sili, he won’t say a word.

Hearing this, Zhao Mengjin seemed to piece together some clues, which surprised her: "Are you trying to say it’s about my aunt’s hearing? Isn’t she unable to hear anything?"

In fact, many people believe Gu Nuan doesn’t appear to be completely deaf because Gu Nuan’s behavior is too much like that of an ordinary person, making it difficult to remember this fact constantly. Therefore, people close to Gu Nuan tend to easily forget this point. Only her enemies, upon encountering Gu Nuan, would exploit this aspect to launch attacks, which undoubtedly became Gu Nuan’s magic treasure for countering her foes.

This is why Ou Yanan had never mentioned it before. Gu Nuan’s current hearing condition, in her perspective, seemed quite alright. Whether in work or life, it hadn’t caused Gu Nuan any inconvenience.

But recently, the more time he spent with her, the more anomalies he noticed. Regarding this, he had to admit that this time, his decision to come out with their family was not because of Little Mingli’s coquettishness but purely out of concern for her health condition.

Regarding this, Zhao Mengjin had long been aware. At this moment, she confided in him: "When you said you were bringing the kid out, I found it strange. I thought you were the kind of person who never acts without incentive. How could you possibly come out to bring a child? That’s completely implausible. Your goal as a doctor isn’t to take care of children."

"Hmm."

"If I could detect it, can my aunt and uncle be completely oblivious?"

Ou Yanan blinked.

"If you want to keep it from my uncle and aunt, I think you need to put in more effort," Zhao Mengjin said, and then with a solemn expression, asked, "What’s really going on?"

While pondering over her warning, Ou Yanan said, "She wasn’t completely deaf initially, she could hear with one ear."

This answer didn’t seem to provoke much surprise or discomfort in Zhao Mengjin. Just thinking about how Gu Nuan had faced numerous enemies along the way, it was only natural and completely understandable that for self-preservation, Gu Nuan had to do this.

"Now, are you saying my aunt’s condition has worsened?"
