Yeah, I didn't mean that he would physically be transferred to the realm of the Palace of the Dragon King if it's some kind of place but rather his soul would be trapped inside it for eternity or for a very long time.

I got confused since here on Narutopedia, The Palace of the Dragon King is classified under jutsus so I was wondering if it was actually confirmed that it was some kind of technique or jutsu.
