White Sun Holy Mother remained silent, and the fear in his eyes also vanished. He was just calmly looking at Yu Ziqing.
He was not afraid of death, nor of torture.
Death was merely a new beginning.
Yu Ziqing didn't intend to interrogate him, knowing it would be futile.
In Yu Ziqing's understanding, the White Sun Holy Mother came out of nowhere, much like the Fourth Heavenly Calamity descending directly upon a person.
Have you ever seen a member of the Fourth Heavenly Calamity afraid of death?
Every one of them faced death calmly, started anew, and then, if not successful in revenge, they would continue endlessly; for instance, a Valkyrie could die dozens of times, and it was just trivial.
Thus, Yu Ziqing was also aware of the mindset of the White Sun Holy Mother; as long as his core secret wasn't exposed, all other tortures, interrogations, and death were merely trivial.
