Since the beginning of the world, Pangu's twenty-four teeth have turned into twenty-four palace stones, and each palace stone contains different palace arts. The palace arts restrict each other. Four chosen people have obtained the palace stones, so they can learn this palace arts and protect this mortal world. The four chosen people spread their branches and leaves in the mortal world, thus forming different palaces. Each quarter has a guardian palace, and the quarters it protects are also different. Therefore, the weapons, habits and palace skills of the people in each palace are also different.
The world is just like this: people who are still alive always make despicable complaints about the living and hypocritically miss the dead.
Purpose: Cherish the people in front of you
