Li Fan, holding an iron sword, leaped down from the mast. On the crimson ridge of the sword in his hand, a blood-red aura permeated. Although not as formidable as the Blood God Child initially, heavy like a mountain, it converged into a door-sized massive blood-colored sword!
This was the Blood Refinement Dao Breath imparted by Xuantian. The principle was quite simple: it involved mixing Dao Breath with blood. Although the methods might vary, Xuanmen experts like Xuantian were most skilled in cultivating essential qi, so fundamentally, Blood Refinement Dao Breath shared the same nature as the foundational techniques of Divine Teachings' Blood Sutra Scripture.
Thus, Li Fan could naturally utilize the Blood Refinement Dao Breath, practicing the Blood Record Divine Sword, and executing the moves of Blood Charm Sword!
