The Tang Family's most formidable formation was the Deca-Dire Formation. In the past, during the great battle with the Witch God, had it not been for the Sixth Elder who was accidentally slain by the Witch God, the ten Elders combined could have held their ground against the Witch God in the Golden Core Realm.
The Deca-Dire Venomous Serpent Formation, a terrifying variant derived from the Deca-Dire Formation, made its usage even more horrific, particularly given the venomous nature and fearless sacrifices of the Serpent Guards.
Once trapped in the formation, it was akin to being in a snake pit, surrounded by terrifying venomous snakes in all directions - a situation allowing no way out but death!
