The seventh trial was called the Furnace, which was quite similar to Lu Hong's past experience with magic fire body refining, but this was of a much lower grade.
There was no standard benchmark for passing this trial. Trialists needed to endure and train their bodies under the ever-increasing flames. The lowest known temperature for someone who passed was 380 degrees, but as long as you did not faint from heatstroke, the temperature could be infinitely increased until the trialist reached their limit.
Right now, Lu Hong was sitting cross-legged in a room full of flames—a scene conjured up by the magic array. Flames encroached upon him at all times.
The initial temperature was very low, akin to warm water. Lu Hong even thought it was too cold for a bath.
However, as time passed, the heat seemed fitting for a sauna.
Having experienced magic fire body refining and with his resistance training maxed out, Lu Hong naturally passed the trial with ease.
