Battle of Zhuolu part 18
When Ouyang Shuo walked out of the teleportation formation, a system notification sounded in his ear.
"System notification: The Battle of Zhuolu has officially ended. The Yellow Emperor tribe, Fire Emperor tribe, and Jiuli tribe have automatically entered the game and are hidden tribes. Players can search for them."
Hidden tribes meant that they hid themselves off from the world and wouldn't proactively interact with the outside world. The historical figures in the tribes were also very difficult for the players to persuade. If players were so lucky to find their tribe, the largest possibility would be to get a reward. Overall, it had little effect on the wilderness.
This was also because historical figures in the wild era were termed as unrecruitable bosses who lived in their palaces and didn't go out. As for the others like Limu and Feng Hou, in the later eras their ability was normal, and there was no recruiting value.
