Fang Jie continued his research into his Death Aura Domain, which had now truly become a Domain. In other words, he was able to infuse a stream of Death Energy into his Domain, and that was the true nature of this Skill.
Under the influence of Death Energy, even other Demigods would suffer terrifying corrosion.
This Death Energy was not like what Demigods had before; this was true Death.
No matter the origin of a Demigod, facing this Death Energy, they would indeed approach Death unless they countered it with their own strength. Even then, they could only slow it down, and the consumption of their own Life Force would be immense.
If one had not reached the Demigod Level, they would easily die when facing this Death Energy.
It didn't matter how long their lifespan was or how robust their Life Force, the outcome would be the same.
Death Touch was simply more straightforward; it was formed to kill enemies.
