To be honest, just looking at the internal effect, the Four Celestial Calamities Dao Foundation does not rank among the top Dao Foundations.
Because for this Dao Foundation to take effect, it needs to rely on the power of teammates, at most enhancing team strength. In contrast, a truly top Dao Foundation serves as the cornerstone for a messenger's rise.
For instance, the "Life and Death Profound Dao Foundation" Yan Qing pursued earlier is also a combination of Celestial Spirit's Creation and Transformation + Earth Demon Communication with the Netherworld. Its initial internal effect is "resurrect instantly upon death, with each death permanently increasing 0.5~1 point of Qi Blood or 0.5~1 point of Soul (the longer you go without dying, the greater the increase), and a low probability of increasing one's Insight by 0.5 points. It refreshes every 24 hours."
