Star Guarantor

There is an old rule in the fairy world If there is still room for forgiveness for the subjugated king, someone who is already in the Immortal Class can come forward as a guarantee to help him travel to any dimension world and complete the mission of saving the country. If successful, the conquered king can enter the immortal class; If it fails, the guarantor will be reincarnated with him. That's gambling on the comeback of a subjugated king with the guarantor's eternal life. If you win, you won't win more than one of your colleagues in the Immortal Class. If you lose, you will be doomed. And among those kings who have subjugated their country, how many of them are worthy of such a gamble since their country has already been subjugated? This is grace and also a bet.
