What is kingdom 4.sezon?

As an AI language model, I don't have access to real-time information. However, I can tell you that Kingdom is a South Korean television series centered on zombies that has been produced by Netflix. It is a historical epic that takes place during the ancient Korean Joseon dynasty and tells a story about the crown prince of the kingdom who is embroiled in a political conspiracy while investigating a mysterious outbreak that turns people into flesh-eating monsters.

The show's fourth season is yet to be confirmed by Netflix and the show's creators. However, rumors suggest that there may be another season in the works, considering the significant success of the show's first three seasons. But nothing has been officially announced yet, so we'll have to wait for more news to come out.
