It's fortunate that it was Gu Yuan; otherwise, if it were someone else, even a true disciple of a major cultivation sect like Medicine King Mountain or Gu God Sect, it would be difficult to withstand such a trial and they would be burned alive inside the fire furnace.

Even if his cultivation was exhausted, he could replenish his true qi and sustain himself for quite a while.
Thus, after another moment as brief as sipping tea, the true flames around him swiftly diminished, the heat gradually dissipated, and even the nine fire flood dragons above his head collapsed, turning into clusters of true flames.
After a dizzying twist, Gu Yuan blinked and found himself outside again.
As for the fire furnace treasure in front of him, it quickly shrank, transforming into a small, exquisite dark red furnace the size of a fist.
