Chen Mobai had also considered many options for his Core Formation's spiritual land.
Since he was to form his core using the Pure Yang Scroll, the most suitable place for him would naturally be a Fire Vein land.
Both Danxia City and Crimson Mountain were Fire Attribute Spiritual Lands, highly suitable for him.
Among them, the spirit vein in Danxia City was particularly suitable due to its core being the Biyu Wutong, which also contained Wood Qi, making it even more compatible with his dual-phase cultivation technique.
Chen Mobai had thought about forming his core within Cinnabarite Institute, and although its spirit vein level was not as high as Crimson Mountain's, with the addition of Spirit Stones, it wouldn't be inferior to Giant Tree Ridge.
Moreover, forming his core here had another advantage; it would confirm his Enlightenment Path Golden Core achievement.
