I live in a desert island property

Resurrection of spiritual energy, mysterious arrival, changes in rules, and changing times.
I am the original superpower and the strongest in the world. In fact, I didn’t die, I was just trapped on a deserted island, looking for a batch of precious treasures from foreign civilizations.
Now there is only one last step left, I need a rescue team to transport this batch of treasures back. After returning to the earth, you will immediately become billionaires, riches, fame and wealth, all at your fingertips.
What? No one came to help? Then…then I have no choice but to swim back by myself, don’t blame me for not giving you a chance! I can really swim back by myself!
