Only a few minutes after Wilson left, Zero's synthesized voice broke the silence in the office again.
"Professor, Academician Fang Xu is here to see you."
Lü Yongchang raised an eyebrow and murmured, "Fang Xu?"
"What brings him here?"
Unable to figure it out, Lü Yongchang raised his voice slightly and lifted his right hand to massage his brow. "Zero, let him in."
As soon as he finished speaking, he heard the office door open.
"Yongchang!"
Fang Xu's booming voice rang out from the doorway.
"What is it?" Lü Yongchang lowered his hand from his brow and asked, looking a little weary, "Aren't you supposed to be taking these few days off?"

Fang Xu did not answer immediately. Instead, he turned and closed the office door, then strode over to the desk.
Lü Yongchang frowned slightly, unable to fathom what Fang Xu was doing.
Was there anything left that required this much caution?
"What exactly happened?" Lü Yongchang instinctively lowered his voice. "Why are you being so careful?"
As he spoke, Lü Yongchang glanced at the robot standing beside his desk. "Zero, take precautions."
"Understood." As the synthesized voice sounded, the open windows in the office swiftly closed, and even the curtains were drawn.
Under Lü Yongchang and Zero's gazes, Fang Xu pulled out the chair in front of the desk and sat down without hesitation.
"What should we do about the core?"
Without any preamble, he got straight to the point. "I've been thinking about this throughout my days off."
"Just thinking about that thing keeps me from sleeping soundly."
"It's too dangerous!"
Lü Yongchang's expression changed immediately.
The core.
Within the Academy of Sciences, that term referred to only one thing.
The two-dimensional core [Hua] had given them.
