In this chapter, Little Eustacia finally takes action, using an arrow to follow the invisible track of the ship. The arrow follows the ship's course, while the original arrow goes to find its original course. The arrows are so hard to miss that they are called "disguising swooshes" . This is a skill that little eustacia is very good at. He tells us that he has only one chance to use this skill, and that is to use it to refine his team. He is afraid that he will be beaten up before he can recite the spell, so he decides to use the refining skill to shorten the spell. He thinks that Old Man and Madame Jourdan are all god-level players, but that they can only hit the target with one attack, so they can't defeat the siren. However, if Old Man can shoot the siren, everyone can recover. The refining skill is now flying towards him, and he wonders where he is. He wants to know why he is being attacked, and what is going on. He decides to take advantage of the moment when the "tidal requiem" is feeling low.
