Lu Cang continuously tempered his physical body... Then, he directly used Sacrifice Soul to enhance its strength.
As a former Level 0 Warrior, his physical limits were too low.
Sacrificing souls had only elevated his Physique to that of a Level 1 Warrior.
Now, Lu Cang directly sacrificed ten thousand souls to temper his Physique.
He soon felt a bottleneck.
However, he could push past this bottleneck by circulating Blood and Demon Tempering. It seemed that strengthening his Physique through the soul-refining was one method of improvement...
...while the tempering from Blood and Demon Tempering was another entirely.
After about five minutes, Lu Cang felt his Constitution had hit a plateau.
'It seems I can't break through any further this way.'
"Kumironi, I want to advance again."
"To Level 2 Warrior."
Kumironi's expression was complicated. She sighed softly. "Very few people in this world advance three times in a single day."
