Silver Disk River System, spanning a diameter of about 1.2 million light-years, developed earlier than the Sky Plate River System, is currently dominated by the Silver Disk Kingdom, which governs five duchies and several dozen ordinary kingdoms.
The Silver Disk Kingdom currently possesses five great Immortal Powers, with the strongest force being the Silver Disk Royal Family "Tuoba Clan".
The Tuoba Clan has been developing the Silver Disk Kingdom for more than 30,000 years, and now the Tuoba Royal Family owns two Star-Annihilating Starships, with just the publicly known Ultimate Dreadnought Captains amounting to five, commanding nearly 200,000 light-years of Star Domains, rightfully the overlord of the entire Silver Disk River System.
