To peek at such level of battle, Sword Star must exercise caution.
To speak the truth, Sword Star's level hasn't reached 30 yet. Unless he actively enters, he theoretically wouldn't be assigned to an S-level dungeon.
But his Sword Cultivator reincarnation adds too much value, it's a reincarnation that can only be completed in the Realm of Reason, and he's been in the top ten of the Realm of Reason reincarnation list for years.
Even though he can't fully exert the power of a Sword Cultivator now, once he operates at full power, he won't be afraid to duel anyone below.
This barely made him standard enough to enter the Steam Phantom Dungeon.
The good news is, the Steam Phantom Dungeon has never appeared before, it should be a newly generated S-level dungeon, and its difficulty shouldn't be much higher than A-level dungeons.
The bad news is, no matter how simple, an S-level dungeon is still S-level, and leaving alive requires being ready to exhaust all life-saving measures.
