What do you mean by the period of protection in the kingdom?

This can protect the territory from attack. Kingdom era provides a 180-day protection period for novices and budding new players, during which players can get a good development. However, after 180 days, the kingdom era entered a more cruel middle period, and the big fish eat small fish and the law of the jungle were vividly reflected. If you don't protect yourself, you will be easily bullied by other alliance bosses.
