Starting as a Wallfacer, his defection to the Three-Body Problem shocked the world.

Lin Xuan paused for a moment. Although he didn't say anything, he had already included Zhizi in his list of key observation targets. He even suspected that his sudden amnesia was more or less related to Zhizi.

If Zhizi knew Lin Xuan's thoughts, she would probably be heartbroken. She had finally done a good deed, but Lin Xuan immediately pointed the finger of suspicion at her.

“Mr. Lin Xuan, let’s end the small talk here. The situation on this planet is a bit complicated right now, and I need to talk to you alone.” Zhi Zi then invited Lin Xuan to speak privately. Lin Xuan did not refuse, and then took Zhi Zi’s carrier chip from Simothers and installed it into his watch face.

Suppressing her questioning tone, Lin Xuan glanced at the three people beside her, signaling them to wait a moment, then turned and walked a few steps away. Only after creating some distance between herself and the others did Zhizi speak again.

"As usual, there are still three questions."

Zhizi's projection extended three fingers, but as if remembering something, she added a sentence afterward.

"You are not allowed to ask me about the Grand Unified Theory of the Universe."

Lin Xuan was taken aback, but then nodded: "Okay, first question, how did you end up here?"

"If I remember correctly, you should still be being held in the Star Ring Group's prison, right?"

Upon hearing this, Zhizi couldn't help but smile.

"Does Mr. Lin Xuan really believe that he can imprison me with just a few of them? Or did he really think that when I played chess with Mr. Lin Xuan back then, he could imprison an observer who was created by an advanced civilization with just a barrier made by a level two civilization?"

What Zhizi said was true. Lin Xuan was imprisoned back then entirely because he wanted to be imprisoned there. He wanted to maintain the direction of the plot as much as possible so that the variables could always be in his own hands, instead of like now, where someone has taken a piece of his memory out of thin air and he doesn't even know who did it.

"Oh, and I can give you another message as a bonus," Tomoko said with a smile.

“Cheng Xin is dead. I forged your handwritten letter and sent it to them before I died.”

She had originally thought that Lin Xuan would either be extremely angry or relieved upon hearing the news, but clearly, neither was the case.

He was very calm, seemingly not caring at all whether the woman lived or died.

"So, as the rumors say, you actually wanted to kill her from the very beginning?"

This is what Zhizi has never been able to understand. Although Cheng Xin may pose a certain threat to human civilization, it is far from enough to warrant Lin Xuan personally targeting an ordinary person.

That's right, she's just an ordinary person. In Zhizi's analysis report, Cheng Xin is so ordinary among these monsters that she's almost an anomaly. It can be said that she has absolutely no abilities. Even compared to Ai AA, the two are not even in the same league in terms of decision-making intelligence.

Well, she was more like the only casualty of this war. If Lin Xuan hadn't paid special attention to this woman, Zhi Zi wouldn't have even noticed her existence.

Many times, Zhizi had considered whether she could support Cheng Xin as a puppet, but she failed several times. She was too mediocre, so mediocre that Zhizi felt that anyone else she picked from the human population might be much better than her.

Lin Xuan did not answer Zhizi's question directly, but instead asked her second question.

"Are you a creation of Number One, or a creation of the Trisolarans?"

"What difference does it make?" Zhizi's face still held that smile: "You can see me here now, which proves that I now have the opportunity to participate in this final battle, regardless of who created me."

"That's true," Lin Xuan nodded slightly, acknowledging the statement.

"Don't you plan to ask about the mechanical Earth, or this planet?" Zhizi asked curiously.

"It seems like you're completely indifferent to the affairs of the six Earths."

Lin Xuan shook her head and asked her third question, which, unsurprisingly, was still unrelated to the mechanical Earth.

"Then... one last question: what if I wipe out all three Earths before the Earth Alliance arrives here, or before the final battle even begins?"

When the question was asked, Lin Xuan could clearly sense a subtle hint of panic in Zhi Zi's usually calm eyes. She seemed genuinely surprised that Lin Xuan would ask such a question.

Of course, Zhi Zi didn't know that Lin Xuan asked this question because of the system.

Shocked to discover he was missing 100,000, Lin Xuan began to doubt everything around him. But just because he could be affected didn't mean the system could be affected. So, he started searching for clues within the system to see if anything was wrong with it.

After searching through it, he indeed found something different.

In his system interface, a new option called "Civilization" appeared. Lin Xuan remembered very clearly that her previous system did not have this feature; it appeared suddenly.

When he switched to the interface of this civilization, he saw something unexpected.

Current civilization name: Spark.

Current civilization technology: Level 1.5.

Current population of the civilized population: 1350.

If he remembered correctly, Zhizi had just told him that she was the one who founded the Spark Organization, right? Then how come his system had this extra thing?

Although Lin Xuan had absolutely no recollection of this organization called Spark, the fact that it appeared in the system suggested that it might be related to her lost memories.

Therefore, the suspicion surrounding Zhizi has been raised to almost the maximum level. Lin Xuan is now 100% certain that Zhizi's appearance here is no accident. She may have seen her more than once, or rather... it may not be Zhizi at all.

This is also why Lin Xuan asked it the second question. He really wanted to know what Sophon had experienced after arriving on Machine Earth. After all, in his eyes before, this intelligent being created by the Trisolarans was not so intelligent, or rather... its intelligence was derived from the Trisolarans' intelligence. After the Trisolarans were completely destroyed, Sophon completely lost its threat to him. This is why he could put it in the Star Ring Group and let Ai AA take care of it.

To everyone else, that thing was nothing more than an empty shell.

But now, looking at the Sophon in front of him, although its memories and appearance are still the same as the Sophon in his memory, his own memories as an observer can be arbitrarily altered by others, let alone the Sophon, which is an AI.

Perhaps... this thing in front of me can no longer be equated with ordinary artificial intelligence.
