Riding his Cloud Escape, Yang Jing chose not to rescue Song Min, who was trapped by swarms of Blood Shadow Mosquitoes.
The Blood Shadow Mosquitoes were, after all, just tools used by the Dark Spring Demon Sect to collect lifeblood. Their reproductive speed was astonishing, and when dormant in their egg stage, not even Bright Qi Talent could detect them. Naturally, they also had their flaws. Namely, due to the limits of their innate Talent, their Demon Power was extremely weak before their Third Transformation.
A single Blood Shadow Mosquito had practically nonexistent Demon Power.
This meant they were almost incapable of breaching the defenses of a Tier One Upper Grade or higher Defensive Spiritual Artifact. This flaw wasn't a problem when dealing with mortals or Independent Cultivators, but it made them highly ineffective against Sect Cultivators.
