After obtaining the Corpse Puppet of the Giant Claw Lord, Ma Lu had thought about using it to launch a surprise attack on Sanrew.
However, Black Horn was, after all, part of the Golden Hunting Group, and a beast like the Giant Claw Lord obviously wouldn't be able to kill Sanrew.
Moreover, after testing it, Ma Lu found that the Corpse Puppet in its current state only retained about 70% of the Giant Claw Lord's base attributes, especially the speed, which had halved.
But this was understandable; after all, it was dead and certainly not as agile as when it was alive.
Luckily, this wasn't a problem, as Ma Lu had compensated for the lost attributes with other blessings. Not only had he compensated for them, but he had even exceeded them a bit.
Furthermore, the Purple Blessing [Full-Body Hardening] granted the Corpse Puppet immunity to all attacks on its weaknesses, except for decapitation.
But relying on these alone wouldn't be enough to kill Sanrew.
