The Skull Treasure Artifact was like a divine weapon, its hardness beyond imagination. The Spirit Swords struck it, sending sparks flying in all directions, yet they could not break through it.
However, the force carried by the Spirit Swords was immensely powerful. After a round of slashes, the skull was immediately knocked askew, its advance instantly obstructed.
"Kill!"
While controlling the Spirit Swords to ceaselessly strike the skull, Su Mo attacked Wu Shan.
Sword might surged mightily, Sword Qi crisscrossing through the air as it swept toward Wu Shan like a canopy blotting out the sky.
"Trifling tricks!"
Wu Shan was utterly unafraid of Su Mo. Both palms shot out, profound strength gushing from them and transforming into skulls that lunged at Su Mo.
Rumble rumble rumble!!
Explosions rang out without end, and devastating shockwaves swept up into the nine heavens.
Sword Qi collided with the skulls. Some were swallowed and extinguished by the skulls, while others exploded together with them.
Neither of them stopped attacking, leaving the other no chance to catch a breath.
Wu Shan continuously conjured skulls of profound strength with his left hand, while a long spear appeared in his right.
The spear thrust violently, its shadows layered upon one another as they tore through the air toward Su Mo.
With the Billion Demonic Sword in hand, Su Mo did not fear his opponent at all. His surging Sword Qi clashed head-on with Wu Shan's attacks. After several hundred exchanges, neither side had gained the upper hand.
How could he be this strong? Su Mo's expression darkened slightly. He had truly underestimated Wu Shan.
Even with the aid of the Demonic Sword, he still found it difficult to defeat the man. Had this been before he obtained the Demonic Sword, he would have been no match
