When almost all those inside Hai Di's domain were about to succumb to their early graves, a crimson bubble intruded on the dark domain. It continued to spread until the dark domain reacted and counteracted it. The two bubbles were locked in an equilibrium.
Not all part of the dark domain was intruded upon by the crimson one. In that part, the shadows continued to erode the poor people trapped inside. As for where the crimson domain intersected, the people inside found that the pressure encumbering them had diminished greatly. They could move again. Some quickly fled the area. While a few showed their loyalty by resuming their assaults and sending ranged attacks at Hai Di, only for those attacks to fizzle when they got close to Hai Di. Seeing that, they joined their comrades and fled the area.
The crimson bubble was Yao Ai's domain arts. With her interference, the effect of Hai Di's domain could be nullified.
