In an instant, everyone's eyes were dyed red.
The soldiers climbing the ladders screamed, rolling down in flames, and those below were caught off guard, engulfed by flames suddenly spewing from the ditches. They screamed, shrieking and rolling on the ground, some even stepped blindly into empty space and fell into the ditches.
The thin layer of soil and tree branches covering the ditches was burned away, revealing countless clay pots densely packed within, almost half a person's depth and width.
They were filled entirely with tung oil!
No wonder two fire arrows could ignite them, completely halting their attack.
Those in the rear watched the two towering walls of fire, obscuring the entire Fufeng City Tower, swallowing the ladders which were soon burned to ashes, leaving them unusable, while their troops dared not approach the walls, helplessly watching their comrades struggling and pleading in the flames.
Xue Xian was stunned at that moment.
