General Shawn reflects on being dismissed after ten years guarding the Demon Cave as Martial Saint Wendy Smith arrives to challenge him. Wendy reveals that a Purifying Seal Formation protecting the cave has weakened since Shawn left the core sword formation, whose inscriptions she claims hold the true power. With the outer seal broken, demons threaten to escape. Wendy orders a small team to investigate inside the cave while the rest guard the entrance, insisting no one enters or leaves without her permission. As they prepare to enter the demon’s lair, the balance of power within the cave hangs in jeopardy.
