By all rights, Chen was pursuing Gu now not to avenge himself, but to reclaim the seven thousand realms under Gu's control. That way, he could make amends and perhaps exchange them for another realm, compensating for Shadow Realm's losses and reclaiming his place in the Supreme Sequence.
That was what everyone in the outside world believed.
That was why Chen was pursuing Gu at all costs.
In that case, if Chen couldn't be sure Jia Realm was hiding Gu, he shouldn't have provoked them.
"Your Excellency has misunderstood," Five Thousand Jia's voice rang out. "Gu isn't here."
Lu Yin replied coldly, "You're the ones hiding Gu. That Two Thousand Jia let slip plenty. Did you think I wouldn't notice?"
"Hand Gu over at once, or I'll tear Jia Realm apart."
Five Thousand Jia turned furiously toward Two Thousand Jia. "What exactly did you say? Do you realize that if it's confirmed we're hiding Gu, the whole outside world will turn its eyes on us? The Karma Master Clan won't let us hold seven thousand realms. We've always kept a low profile and avoided all disputes because we don't want trouble."
Two Thousand Jia didn't know how to explain itself. "I really didn't say anything. I..." It regretted going to Chen. How did that guy even think?
"I'll count to three. If you don't hand Gu over, I'll search for him myself." Lu Yin's voice rang across the starry sky, heard by countless beings. Many of them weren't from Jia Realm.

"Two."
"So you intend to pin this on Jia Realm?"
"Three.
