Living on a Small Island, I Became the Owner of the Island

I was lucky enough to win the grand prize, and I embarked on a European trip with great joy. Unexpectedly, this was an adventure with no return. I accidentally came to the island and fought alone to see how I rose from a rookie to the island owner. Ps: 1. No male protagonist, no bestiality; 2. There are delicious food, cute pets, and a little gold finger.
