The current state of the kingdom is still in the process of being improved because there are still many certain areas that are very difficult to fix. Like the ruins of some fairly large and thick walls. And the ruins of a fairly high building made the repairing process a bit slow because many of the residents who should have been good at fixing it were hit by the attack and ended up having to be in the healing room.
Three days after the surprise attack, they did not return. Either because they feel lost in the fight or they choose to run away to perfect the tactics of their new plan. Because after knowing that Vino got a new power that was so big, it made Kronos think twice about fighting against Vino.
Because he realized that his strength was not comparable to Vino's, and in fact, he was very different from Vino. Luckily at that time, Vino's focus was shifted to Bryant if not, then maybe Kronos and his followers returned from the Kingdom only their names were left.
