"Have you figured out why?" Lamia looked toward Aiden.
"It's simple," Aiden laid out his guess, "Professor Dodge is dissatisfied with the research results from the Empire, but he might have been expecting Gistas's achievements, and Gistas indeed made some kind of breakthrough. He doesn't want to destroy Gistas's 'infection' plan, but rather to steal its research outcomes to stabilize his son's condition."
Gistas Kingdom's Intelligence Bureau was deploying the "infection" plan, and only at the beginning did an officer go missing. Afterward, whether the plan encountered a bottleneck, was temporarily shelved, or obtained a significant breakthrough and was restarted, Professor Dodge who was stranded in Sunset City, did not make moves like the Empire did.
