Yusuf Zuck, along with the Rat King, indeed went to the Three Lives Platform. Now transformed into a Nirvana Immortal, his next step is to retrieve his memories. He subconsciously feels he is extraordinary.
Because he lives in the Immortal Realm in the body of a mortal yet is not repelled by the Heavenly Dao, and because he directly achieved the level of Golden Immortal after absorbing the immortal essence from the Immortal Transformation Pool.
Based on these two points alone, he is undoubtedly different from others.
Furthermore, questions like who he is, where he is from, whether he has family or relatives, and why he lost his memory, all need answers. Otherwise, he would live aimlessly, not knowing the purpose of life—what's the point of living like that?
The Three Lives Platform is a remarkable place in the Yangle Immortal Realm, accessible not to just anyone.
It's not that entry is forbidden, but ordinary Immortals simply cannot get in.
