Ayden Acme's training involves the Great Self-Contained Divine Powers, and naturally, he possesses methods for self-preservation or concealment. Yusuf Zuck believes he can protect Raul Graves, as if Raul were truly to die, Yusuf's family vengeance would remain an eternal mystery, so he must ensure Raul stays alive.
However, Yusuf Zuck's current concern is how to enter Seven-Star Island. It's important to note that Seven-Star Island has a barrier, and inside, it's like a vacuum, isolated from the vast starry sky, making a silent entry through this barrier seemingly very difficult.
Of course, he could use the Door of the Other Shore, but he's uncertain if it would cause any vibrations.
"No matter, even if it causes vibrations, I will still enter. Ayden, be prepared." Yusuf deeply inhaled, and just as a sudden thought occurred, his entire being entered Seven-Star Island instantly.
