It takes a special kind of stupid to try and blackmail a living God in a world of known gods. Especially when you already know you're guilty of blasphemous acts towards the gods. Even if it turns out it's all BS why risk it? Sure people lose records of civilizations that faced divine punishments and disappeared, but there's like... very recent physical evidence that the MC isn't someone worth stepping to. At the very least you'd think a country & church with the resources of a tower at their disposal would do some basic research beforehand.
Anyway, the bit of the gods getting excited to descend was fun and the conquest continues with a nation established. Wonder how the nation would be viewed in like a hundred years. Floria will be the first queen and a high human and the sponsor of the nation is the only male living God and Floria is one of his lovers who will eventually also give birth to his children. That's like an actual religious nation. It's one of those old civilizations that proclaimed their royalty was descended from godhood, but it's not a claim and is happening in real time (in universe).
