"Another one." David frowned at the sudden notification; he wasn't expecting that he would encounter such a notification today. According to his calculation, it should have been tomorrow.
Whatever! David sighed and quickly moved, his body shuttling through the void, and in a few minutes, he arrived back in his room and sat down cross-legged.
He knew as long as he accepted the Crystallization of Life, he would break through to the next realm.
After steadying his breathing, David calmly chose the first option and decided to extract the poor guy's Crystallization of Life.
Immediately, he felt foreign energy merging with his Crystallization of Life.
David quickly focused inside his spiritual space; he did not want to miss any changes.
