Zhao Daochuan was not born in Xinglong Origin, but was a clansman from the ancestral Taifu Mountain.
This person was obsessed with the way of formations throughout his life, especially skilled in construction, hence, he was highly valued and favored by Zhao Xuanjing.
As is well-known, the study of formations is broad and profound, arcane and elusive, and its difficulty is considered first among the Hundred Skills of Immortal Cultivation; not only is it hard to get started, but it's even harder to progress.
A third-rank Array Master is often more rare than a Fake Pill True Immortal.
Zhao Daochuan was a Quasi Third-rank Array Master, and his life's greatest achievement was the Quasi Third-rank compound array constructed outside Zhao's Secret Mansion: the Earth Light Array.
