If one really must compare, aside from the two top intelligence forces, Sky Mechanism Pavilion and Bai Xiaosheng, the many immortal sects presided over by Taoist Lords simply couldn't match the information they had collected.
After all, there was certainly a gap between them at first, but after the development of ten thousand years, with the presence of Longevity Taoist Monarch, the first person under heaven and earth, they had more than enough time to make up for many shortcomings.
After ten thousand years of accumulation, aided by the prestige of Pei Xuanjing, Shenxiao Sect was able to recruit countless genius disciples and cultivate many powerful cultivators.
When these powerful individuals came together, they formed the now immense Shenxiao Sect. Aside from a slight difference in the number of peak-level True Immortals, in terms of core strength, Shenxiao Sect was in no way inferior to them.
