In the alchemy room of the secret chamber.
Xia Zhou excitedly rubbed his hands together.
The discovery in the "Vitality Recovery" excited him greatly. This talent was the greatest source of vitality attribute value, leading to a substantial change.
A simple calculation would reveal that to recover the vitality of a creature after death, only about 100 Blood Element Servants were needed around it.
If more blood runes were invested into "Vitality Recovery", the number of Blood Element Servants could be further reduced.
The red vests used as Blood Demon Spell protectors were made of a single Blood Element Servant possessing an attribute value of 5.
Xia Zhou planned to change his strategy in the future and use many Blood Element Servants with an attribute value of 1 to form a vest, thus increasing the rate of successful recovery.
