Feng Mu got the answer he wanted.
The Big Black Core was indeed synthesized from the Little Black Core, the instrument was the tool in the briefcase, and the operation method was not difficult. Dark One didn't hide anything and revealed everything smoothly.
Or rather, Dark One thought since the briefcase was in Feng Mu's hands, it wouldn't make any sense even if he didn't say a word, as the other party would eventually figure it out on his own.
Dark One selectively answered some of the other questions.
But as for the purpose of the Calamity Corpse Sect making the Big Black Core, he kept silent, as it was clearly a core secret of the sect.
Feng Mu guessed it might be related to the "Calamity Corpse Transformation" that Dark One accidentally mentioned earlier. He was somewhat curious but not overly concerned.
