Facing the Sleepless Night Family Head, who had clearly entered a combat-ready, intimidating posture, Lin Yu spoke calmly and without haste.

"You saw through me… then there's no way around it. May I ask, when did you begin to suspect, and when did you become certain?"

"From the moment you entered, I discovered I could not peer into your 'soul' or 'life energy,' and I grew suspicious," the Sleepless Night Family Head answered Lin Yu’s question directly, "After all, the last time I met A Luo, he did not possess that ability."

"I serve the God of Wisdom. Whoever can block my probing must be either the envoy of another god or a demigod."

As she spoke, Lin Yu laughed.

"I see."

That really was the expected reason.

"What made you certain I wasn't him?"

The family head stroked her chin and said, "To be frank, your impersonation in all aspects was almost flawless. You're not only skilled at acting and deceiving, you also know A Luo very well. Yet, there are always certain private things between A Luo and me."

"Especially when you imitated A Luo’s retelling of those investigative experiences… you told them very well, mirroring A Luo's previous style and content almost exactly. Unfortunately, when you spoke, you hardly ever bragged about yourself."

"You're far more efficient than A Luo in narration—because you left out the parts where he boasts about his own wisdom and describes others' admiration for him."

Hearing that, Lin Yu was somewhat surprised.

"So I was caught because my face isn't thick enough?"

He couldn't help but sigh inwardly.

Indeed, Fu Luo always managed to reset his own lower limits in the most unexpected places.

The family head clapped her hands: "Alright, state your purpose—also, what did you do to A Luo?"

Lin Yu looked at the Sleepless Night Family Head, who seemed fierce but actually harbored no hostile intent, and began to explain.

"Um, earlier he mentioned a doctor named Watson, right?"

The family head raised an eyebrow in surprise.

"You mean…"

"I am the 'Doctor.' Although my name isn't Watson, I suspect that was my alias," Lin Yu said calmly, "Yes, Bollo and I are very close partners."

The family head crossed her arms: "How do you prove it?"

"How much do you know about us Otherworldly Visitors?"

Lin Yu countered.

The family head replied indifferently, "Enough to know. I understand you usually call yourselves 'Players,' and that most of you regard my world and the other nine realms as a 'game world.'"

Lin Yu took out the Universal General Chamber of Commerce's Seeking Enemy Dagger from his bosom, then lightly cut his own arm.

Then, he activated the Doctor class ability and healed his wound.

Watching the injury mend in almost a second, the family head murmured, "So you are truly a 'Doctor.'"

Lin Yu laughed: "You do indeed understand 'Players' very well, you recognized it at a glance."

"But that only proves your class is 'Doctor.' It doesn't prove you are 'Watson.'"

As she spoke, Lin Yu chuckled, "You asked why I didn't cooperate with Doctor Watson and instead became Hastings… The reason is simple: that Arthur Hastings, the army captain, is also me."

"I have two identities and two class roles—my other class is 'Soldier.'"

As he spoke, Lin Yu casually performed a one-handed handstand to demonstrate the physical attributes granted by the Soldier class.

"If I can disguise myself as Bollo, of course I can, before him, switch from Watson to Hastings."

The family head spoke with surprise, "Truly strange. Your skill is rare even among those Players."

"Then why did you do this to Bollo?"

"Just for fun," Lin Yu shrugged, "Family Head, if you had my capabilities and conditions… wouldn't you be tempted to see how long that clever 'Detective' would take to discover his new partner is actually his previous partner?"

The family head agreed deeply with Lin Yu: "Indeed, that's a very tempting proposition. You have persuaded me…"

"So you used Bollo's identity without his knowledge?"

"It was a spur-of-the-moment decision, so I did not ask his permission. He once boasted to me about his high status in Sleepless City," Lin Yu replied calmly, "You may know that we 'Players' often cannot choose which world we appear in… I arrived here alone this time, and happened upon a somewhat tricky situation."

"So… I borrowed his identity."

Lin Yu responded serenely.

The family head nodded, "I understand. Since you are A Luo's friend… I will not pursue you for impersonating him."

She waved her hand gently, and all the books snapped shut at once.

Lin Yu exhaled in relief.

At this point, it was basically a smooth pass.

That was why Lin Yu had not panicked earlier when the family head exposed him as an impostor.

If she had truly suspected hostile intent, she would have acted immediately.

A Chosen One in her own domain could have restrained him easily.

But because she didn't move, it showed she wanted to hear his explanation.

Because Lin Yu played Fu Luo so well, she could deduce a fact easily: he and Fu Luo must be very close.

After the storytelling segment ended, Lin Yu confirmed the family head's fondness for Fu Luo while letting her infer this: the person before her was not Bollo, but should still be someone very intimate to him.

It was hardly even a deception.

After all, Lin Yu and Fu Luo were indeed partners.

Fu Luo had even said things like "You're Watson and I'm Holmes" on occasion.

However…

Although the crisis was largely averted and his life was safe, the family head's words were not yet finished.

"But you still haven't said… which god stands behind you, and why you insisted on coming to see me."

Lin Yu shook his head.

"I cannot answer either of those questions."

At his answer, the family head reacted at once.

A book behind her opened, and a string of symbols drifted out.

The symbols floated toward Lin Yu, forming a rotating closed ring that spun up and down before suddenly stopping at his wrist.

The next moment, Lin Yu felt his hand lose sensation, and his fingers began twisting involuntarily.

"So it's truly the Universal General Chamber of Commerce's 'Prohibition Bracelet'… It's fine, I have already helped you block it."

"What principle is this based on?"

Lin Yu asked in astonishment.

"The Divine Power Group's alchemy… Your right hand has become an independent life now—so even if you leak secrets, it doesn't matter."

Hearing the family head's words, Lin Yu assumed a serious expression.

"I see."

After a brief consideration, Lin Yu lifted his head.

"This time I came to fulfill an assassination contract."
