I want to watch something similar to "Beacon Triangle, the operator called me a profiteer!" Book.

I Beg the Boss to Write a Novel About Operation Delta

Since Operation Delta is so popular, why didn't anyone write this novel?

Have You Written About the Delta Battlefield? Nowadays, Most of Them Are Writing About Beacon Fire.

Are there fewer people playing Battlefield than Beacon Fire? ? ?
