300 years ago, the Li dynasty collapsed. The territorial states began to rebel and demand autonomy, leading to civil wars breaking out everywhere. Until now, only seven states still exist and compete with each other. The four strongest states include Wu, Jin, Chu, and Li (central government states).
The remaining three states are Karma, Dorje, and Chen. Realizing that the Wu state was gradually becoming stronger and more aggressive, the tenth prince, Chen Yin, returned to his homeland after seeking knowledge in Karma. He aimed to assist King Chen in managing the state and making it capable of withstanding the growing pressure from Wu.​
