No. 5 was actually joking.
If it were possible to fuse the Core Circuit just by eating, wouldn't that make the Spiritual Cultivation Civilization too frivolous and trivial?
She was actually a bit frustrated.
First, she was suppressed and beaten by an old man she always looked down on, and then she watched as Wang Jixuan took away the Core Circuit.
Especially!
Old Sophie's Core Circuit didn't show the slightest resistance to Wang Jixuan!
This was completely different from No. 5's understanding!
No. 5's Core Circuit was inherited.
As the successor of the deceased predecessor, she spent hundreds of years preparing, gradually mastering the old man's Spiritual Energy Circuit, and eventually successfully fusing the Core Circuit Replication Circuit. When the predecessor's mind collapsed and he died in fact, the Core Circuit fused with its Replication Circuit, making No. 5 a formal Spirit Cultivator in the Spiritual Cultivation Civilization.
