"Swoosh, swoosh, swoosh, swoosh, swoosh..."
Countless soldiers rushed to the base of the castle walls and began throwing grappling hooks to climb the battlements.
However, they horrifically discovered that the entire wall had been smeared with something that made it completely slippery, making it impossible to climb or gain any foothold.
Trying to set it on fire, the slippery substance simply wouldn't burn.
Thereby, more than ten thousand soldiers were helplessly trapped at the base of the castle, completely unable to climb up.
"Swoosh, swoosh, swoosh, swoosh..." At that moment, the defenders on the castle unleashed a barrage of arrows and small explosive packs down upon them.
"Boom, boom, boom..."
The densely packed siege army fell like stalks of wheat, toppled to the ground en masse.
Casualties rapidly increased.
Gui Xingfu's scalp tingled at once, not knowing what the explosive devices were.
"Retreat, retreat, retreat..."
