This building was naturally covered with runes and the formation was extremely powerful. The experts of the various True Palaces had their eyes on this place but eventually gave up.
Tang Feng brandished his true sword, and the runes moved along with the sword. A passageway appeared, and the three of them stepped in. Very quickly, they passed through the array and arrived inside the building.
The interior of this building was extremely vast, like an internal world. It was far from the size it appeared on the surface.
In front of him was a huge fire pond filled with black flames. Waves of heat waves assaulted his face.
This was the place where Tang Feng had obtained the true sword.
Not far away from the Flame Pond lay the corpse of a huge bizarre beast.
"At this moment, there is a bizarre beast and a bizarre spirit guarding it. They are very powerful. Before I obtain the Supreme Dao True Sword, I am definitely not their match."
