Tens of thousands of spirit herbs were stored inside, among which there was no shortage of top-tier nine-star spirit herbs, such as the Cangling Wood. Cangling Wood was somewhat similar to human cultivators; it was a tree that had survived the eighty-one tribulations of the Heavenly Tribulation. In other words, whether it was a willow, an elm, or a locust tree, as long as it could survive the eighty-one tribulations, it would become a supreme nine-star spirit herb.
Cangling Wood was one of the three main spirit herbs used to refine the Heavenly Firmament Pill. Because of this, the cultivation of Cangling Wood bore some resemblance to that of human beings.
However, despite its ability to withstand the thunder tribulations, Cangling Wood remained merely a spirit herb devoid of the capacity for autonomous movement.
