Su Yu had no knowledge about the "Holy Silver Federation" and he didn't realize how valuable this invitation letter was.

When he noticed Cindy Doppler staring blankly, Su Yu figured she didn't believe him.

Therefore, Su Yu used some magic to activate the [Watcher Beacon] on him, causing the beacon to immediately burst into a soft blue light.

This beacon was given to him by the Game Supervisor during the Singer War. If he encountered a life-threatening situation on Blue Star, activating this beacon could save his life.

Of course, the beacon also served as the best proof of Su Yu's contact with the Game Supervisor.

Seeing this beacon convinced Cindy Doppler fully of Su Yu's words!

If the invitation was potentially forged (which was highly unlikely), the beacon certainly couldn't be, the aura of the Holy Silver Human Race on the beacon was far too distinct.

In other words, Su Yu will surely be able to enter the Holy Silver Court of Secrets in the future!
