The power to wither was aimed at plant-type feys.
When the dark death power was applied onto plant-type feys, it would cause the plant-type fey to rapidly wither and wilt.
The ability to wither that came from the Dark Death World was not very important to Lin Yuan, but it was still better to have it than to not have it.
Lin Yuan sensed the Dark Death World and noticed that the Sacred Sword Wielding Queen's Sacred Sword Form could use the Dark Death World to attack like it did with other laws.
There was also an additional line that was something of an ability that appeared under the Sacred Sword Wielding Queen's Sacred Sword Form.
This 'ability' was formed from the Dark Death World.
