# 4. Back to the future

It was a tough fight, but each person continued to gather and eventually Class-one guild succeeded in eliminating the “‘404-C0001. Zero Virus”. The guild members, who initially returned to the past, return to the future, and as they expected, the future changed perfectly to peace, not destruction anymore.

The “404-C0001 Zero Virus” disappeared and the beautiful island “C-one Island” resort was waiting for them.

The BUP rewards collected through the project will be able to be used abundantly in “C-one Island”.
