In the moment when the [Blood Spring] was unlocked, Li Fei automatically grasped the relevant information.
This Blood Soul Skill allowed a 'spring eye' to form within Li Fei's body; on normal days, Li Fei could store his Blood Souls in the 'spring eye' and retrieve them when needed.
However, within a 24-hour period, he could only inject up to 1% of his total number of Blood Souls into the 'spring eye.'
Li Fei currently possessed a total of 211 Blood Souls, so 1% amounted to 2.1 Blood Souls.
Based on this amount, it would take him 100 days to store over 200 Blood Souls in the Blood Spring.
This process seemed slow, but the [Blood Spring] Blood Soul Skill was equivalent to allowing Li Fei's 'health bar' to continue growing, with the most important aspect being that there was no upper limit.
Theoretically, given enough time, Li Fei could store tens of thousands of Blood Souls in the Blood Spring, truly achieving 'Myriad Blood'!
