Noah's biggest issue in using the Blood drain spell to boost his body's strength was that he could only use rank 3 magical beasts in the process.
Rank 4 creatures gave more nourishment but he simply didn't have the power to fight them.
What happened with Abel was a fluke, his physical strength was in the third rank and he was also injured, making him the perfect target for Noah's spells.
However, magical beasts had a far stronger body than cultivators, Noah didn't have the confidence to beat the latter let alone the beasts.
'I guess, I'll be forced to strive for quantity over quality.'
Noah thought.
He was inspecting the various boards listing the hunting zones in the Hunter's guild.
'They are quite crowded, as expected.'
He sighed internally as he inspected the low-danger areas featuring large numbers of rank 3 beasts.
'Basically, all the hunters that can't join parties hunting rank 4 creatures are here.'
