Long Xiao had operated the Dragon Cave for tens of thousands of years and buried countless secrets within it.
Once this true dragon returned to the Dragon Cave, he could, like Pu Zhaotian's integration with the "Heaven Forbidden" or the Old Black Turtle stationed in the Panshi Fragment Land, experience a certain degree of enhancement in combat strength.
The injuries He sustained would recover in a short time through the accumulation of His efforts, and the Thunder Divine Power He had exhausted would also be replenished.
In desperation, He could even drain the Spiritual Power veins from beneath the earth at the cost of shattering the Saint Spirit Continent, and He could snatch demon energy from the bodies of many powerful beings of the Demon Race to aid His battle.
Pu Zhaotian, who prided himself as the Shield of Purgatory, would never want to see a whole continent crumble because of his battle with the Old Dragon.
