The 18 Death Knights that were riding Nightmares formed a small line and assaulted from left and right of Lin Li's Light and Darkness Domain. The strength of the Death Knights was actually not too outstanding on the surface. The strongest one had just reached level-19, while the weakest one was at level-18. In fact, after Lin Li subdued and acquired them, their abilities didn't change much, because they didn't have a lot of opportunities to devour soul fire in large amounts.
