The Immortal Spirit Time Lord

Jun Chen, the youngest forging master on the continent, fell in a battle over the continent's greatest treasure, the Pearl of Time and Space. Guided by the pearl, he arrived on the Immortal Spirit Continent. What connection is there between these two continents?

What led Jun Chen to gather twelve companions on this continent and create the faction known as “Shichen”? Each member took one of the twelve earthly branch names as a codename: Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, and Hai. How did “Shichen” rise step by step to the summit?
