Lin Chen was born with "waste spiritual roots", and after three years of cultivation he was still stuck at the first level of Qi refining, and was ridiculed by his sect disciples as "a waste of immortality"; Su Yueli was coveted by evil cultivators because her spiritual roots were too pure, and her Dantian was sealed by the "Spirit Locking Curse", making it impossible to absorb the spiritual energy of heaven and earth. The two met by chance in the "Lingxi Valley" in the mountain behind the sect, and accidentally discovered that there was an ancient "spiritual vein spring" hidden in the valley. The "spiritual marrow" in the spring water could actually nourish the roots of spent spirits and break the spell to unlock spirits.
Lin Chen soaked the spiritual marrow every day, and the waste spiritual roots gradually transformed into the rare "Five Elements Spiritual Roots", and his cultivation speed increased by leaps and bounds; Su Yueli used the power of the spiritual marrow to break through the soul-locking curse, the purity of the spiritual roots increased to a higher level, and she awakened the talent of "spiritual control". Just as the two of them were steadily improving their cultivation and were preparing to hit the foundation building stage, the evil cultivator "Blood Bone Old Monster" who sealed Su Yueli back then suddenly attacked and wanted to seize Su Yueli's pure spiritual root and refine it into a "spiritual pill".
In order to protect the spiritual vein spring and Su Yueli, Lin Chen activated the Five Elements Spiritual Roots and used the power of the spiritual marrow to condense the "Five Elements Spiritual Shield"; Su Yueli used the talent of spiritual control to activate the spiritual energy of the spring and condense it into "spiritual arrows" to fight back. With the cooperation of the two, although they temporarily repelled the old blood-bone monster, they also exposed the location of the spiritual vein spring - a greater crisis was quietly approaching.
