Factions
The world of Zu is separated into three dimensions: Tai, Wu and Xun by chaos and all are far from each other. After you've made a choice, the other two dimensions will become evil forces to disturb you from your inner training. You have to be cautious.
Tai
The trainees in Tai persist on becoming immortals. They believe training should be based on upgrading their skills.
------------------- The power of the element -------------------
The ancient deities have made a supernatural weapon called "Thunder" from the rays of the "Original Crystal". The weapon looks like the gleam of a fountain but possesses strong power. It absorbed the explosive energy of the Magic Rock Battle and then Tai was developed.
Proving their strength is the main principle in Tai. Only through battles can they improve themselves and win the world's peace.
Xun
The trainees in Xun believe training should be based on developing their thoughts. They are sure that subliming their souls is the strongest way to become immortals.
------------------ Soul and Faith -------------------
"Mist" derives from a sense of separation from the "Original Crystal". It is bodiless but can break out awesome power when it is assembled with the spirit of its owner. It has absorbed the explosive energy of the Magic Rock Battle and then the Xun is developed.
Pursuing the spirit accomplishments is the main principle in Xun. After reaching a higher spirit level, you are forwarded to the deity world.
Wu
Purifying the origin of life and making renascence is the main point of the training in Wu. The trainees insist on surpassing themselves and discovering the laws of the universe.
------------------- Renascent Energy -------------------
The beautiful petals of the "Original Crystal" are made into the "Lotus". Every time the petals of the "Lotus" have withered, its core blossoms at once. What an amazingly endless life it is! The "Lotus" has absorbed the explosive energy of the Magic Rock Battle and then Wu was developed.
The senior trainees in Wu stick to studying the origin of everything and the laws of the universe. Therefore, they know the endless energy of life.
