Solitary Rulers had been a second-rate Guild from Shi Feng's previous life. There was an incident where they had been attacked by Black Tower who brought over 200,000 players to attack them. Although they had clashed tens of times, Black Tower was not able to win and instead lost over half their numbers compared to Solitary Rulers' 30,000 player loss. In the end, Black Tower had deployed seven Tier 5 Saint-ranked players and one of their Tier 6 God-ranked player to destroy the guild and lost five of their guild cities. During the final fight between the guilds at Unparalleled City, Solitary's last Guild City, Black Tower had lost two of their Saint-ranked players before another Super Guild took advantage of the situation to siege their cities. Eventually, Black Tower backed off.
