The Tiger Emperor sensed danger and tried to evade, but the Poison Mist Flood Dragon had tightly wrapped around its limbs, leaving it unable to move.
Boom!
The Thunderbolt Spear struck the Tiger Emperor squarely in the ribs.
The Tiger Emperor let out a pained roar. Its shield shattered, and its body was blasted backward into the mountain wall behind it, leaving a massive crater.
It struggled to rise, but a large patch of scales along its ribs had shattered. Blood streamed down its body, and the golden Thunder Patterns had dimmed considerably.
"Again!"
Gu Xiao gave it no chance to catch its breath. Thunderbolt gathered around his fists as he pummeled the Tiger Emperor with blow after blow.
The Tiger Emperor fought back desperately. Thunderbolt collided with thunderbolt, erupting into bursts of blinding light.
Gu Xiao was knocked back several times and spat blood, yet each time, he ignored his injuries and lunged forward again.
Dugu Bo watched from the side without intervening.
He knew this was Gu Xiao's battle. Gu Xiao had to win it himself.
The battle continued for nearly two hours. Gu Xiao was covered in wounds, his clothes tattered beyond recognition, but his eyes grew brighter and brighter.
The Tiger Emperor had also reached its limit. Its 80,000 years of cultivation had been exhausted beneath the Poison Mist's suppression and Gu Xiao's fierce assault.
At last, Gu Xiao struck the Tiger Emperor's head with Thunderous Might. The Tiger Emperor's massive body crashed to the ground, and its golden tiger eyes slowly closed.
A black Spirit Ring rose from the Tiger Emperor's body, so deep in color that it seemed almost purple.
Gu Xiao collapsed onto the ground, gasping heavily. There was not a single part of his body that did not ache.
But he smiled.
