"Kiritsugu, what should we do?"
After returning, Irisviel immediately found Emiya Kiritsugu and recounted everything she had heard from Fang Zheng word for word. After listening to Irisviel's account, Emiya Kiritsugu fell silent for a long time. He merely stared at the tabletop without moving, like a statue. Irisviel said nothing either, simply waiting for her husband's decision.
