Rumble, rumble!
Above the crimson sky of the Fire Domain, thunder suddenly boomed, while layer upon layer of vast clouds gathered.
A massive lightning tribulation had arrived without warning, leaving many powerful cultivators astonished.
"What is going on? Is someone about to undergo a tribulation? Are there actually people inside the Fire Domain?"
"This lightning tribulation is already close to the Great Heavenly Tribulation of the Void Refinement stage. But how could a Void Refinement cultivator remain safe in the Fire Domain at a time like this?"
"Hiss, could it be some clever fool trying to use the Fire Domain to evade their lightning tribulation?"
"This is not a lightning tribulation! A Spirit Treasure must be emerging!"
Someone quickly noticed the unusual nature of these thunderclouds. They differed greatly from an ordinary Great Heavenly Tribulation, and it was immediately concluded that this was not a Great Heavenly Tribulation at all, but a Spirit Treasure Tribulation brought about by a treasure.
Rumble, rumble~!
The thunderclouds continued to gather, as rolling lightning flashed and roared endlessly through the overcast sky. This Spirit Treasure Tribulation was extraordinarily terrifying.
Just as everyone watched intently, a killing sword gleaming with strange purple light shot out from the depths of the Fire Domain!
Whoosh!
The sword was straight and slender, as though carved from a proud stalk of jade bamboo. Looking closely at the layer of strange purple light along its edges, one would discover that it was not light at all, but countless exceptionally fine crystalline threads!
The Immortal Trapping Sword had emerged!
The sword rose and fell amid the thunderclouds, fearless before the terrifying heavenly lightning bolts. It even took the initiative to slash into the depths of the thunderclouds with its blade.
Boom!
In an instant, hundreds of purple sword lights swept forth.
