Guo Feilong took out thirty to forty talismans, each sealed with thunder attribute divine powers and spells, comparable to those unleashed by a late Elemental Infant stage cultivator in Great Perfection.

It's common knowledge that water conducts electricity.

With the power of thunder in the water, it's not just about water pressure and resistance anymore; there's also the paralyzing effect of electricity.

By activating thirty to forty thunder attribute talismans with his mystic power, in an instant, the water in Guo Feilong's Water Prison was imbued with the power of thunder.
