Fang Jie had completely put aside the trivial matters and devoted almost all his time to enhancing himself. Continuing along the path he had previously planned, Fang Jie carried on deducing his new spells.
The spell he was closest to in the aspect of death was the "Death Aura Impact" spell.
This spell directly harnessed the power of death to form an aura of death energy for impact, and it wasn't a direct attack. However, that was because he didn't have many spells early on, so he could only practice what was available.
Now, based on this spell, Fang Jie deduced a new spell, the "Death Aura Domain."
This was not a true domain, but a spell condensed according to the concept of domains. In fact, there are many domain-type spells, not just this one; many people have similar skills.
The difference lies in the fact that using such a skill requires the consumption of one's own strength, which isn't nearly as cost-free as a true domain.
