Game of Death Can Get One Billion? I Want to Play Again

(No system + suspense + reasoning) When I was 18 years old, I accidentally entered a death game involving unnatural forces in the UK. I survived to the end and won one billion, but I lost the most important thing in this game. I started a company in the past three years and it has grown bigger and bigger. However, the capital chain broke and I was desperate. I wanted to enter that god's game again, not just for money, but also to find what I had lost.
