Investigation Book of the Ancient God Incident of the Seven Kingdoms

[Cthulhu×Victoria×Swordsman×Investigator] Wayne was ordered to escort the Eastern envoys to the ancient empire. When he woke up, he found that all seven envoys and others on the ship had disappeared. Only the smell of salt on the ground was left, whispering to the whole ship. Fish scales and tridents are hidden in the curfewed streets of Inslia, but the practice under the moonlight leads people to fall into the dream of the deep sea. Following the traces left by the seven envoys, he will uncover the secrets of the seven realms of the empire step by step, and will also get closer to those crazy ancient gods step by step.
