Leonard Churchill realized that the "substitute puppet" he had made had disappeared, and he also inferred some intelligence.
This was that the people coming from the Southern Continent targeting Ivan hadn't planned to use force in the City of Thieves, but only aimed to stealthily kidnap him.
This directly proved that the visitors were not exceptionally strong, at least not overpoweringly so.
Once the people from the Southern Continent realized they had been deceived and their plan exposed, they would either abandon their operation or forcefully abduct someone.
Leonard Churchill felt it was most likely the latter.
Therefore, the White Family and the Silver Moon Sect, these two "temporary allies," were now very important.
Whether it was the Silver Moon Sect or the White Family, both had clashed with him in life and death feuds numerous times, betraying them was without any psychological burden to Leonard.
