Under the observation of Su Mo's Netherworld Demonic Eyes, the so-called Great Sun Domain was merely a special domain formed from the Great Sun Divine Body, the Sun Martial Soul, and Solar Xuan Energy.
After attacking twice earlier, he had discovered that while the Great Sun Domain dissolved his attacks, the Solar Xuan Energy contained within it was being consumed as well.
Moreover, that consumption was not slow, nearly comparable to the expenditure of Shangguan Hao's normal attacks.
Thus, Su Mo came up with a simple and crude method: drain Shangguan Hao's Xuan energy dry.
Su Mo was absolutely confident that even though Shangguan Hao was a Martial Emperor expert, the Xuan energy within his body could not possibly be more abundant than his own.
That was Su Mo's confidence—he would exhaust his opponent to death if he had to.
"Are you dreaming?"
Shangguan Hao gave a disdainful laugh upon hearing this and said arrogantly, "Looking across the world, among those whose cultivation does not surpass mine, no one can defeat me!"
"Whether I can defeat you or not, you will know soon enough."
With that, Su Mo said no more. With a flip of his hands, a longsword appeared in each hand—the Xuanhuang Sword and the Sky Punishing Sword.
With the nine Destined Spirit Swords guarding his body, Su Mo began attacking with the two ordinary longswords.
Whoosh! Whoosh! Whoosh! Whoosh!
His arms swung repeatedly, and dozens of Sword Qi tore through the void, slashing rapidly toward Shangguan Hao.
Hiss! Hiss! Hiss!
Dozens of Sword Qi slashed into the Great Sun Domain and immediately began dissolving at high speed.
Yet, struck by dozens of Sword Qi, the Great Sun Domain rippled slightly as the Solar Xuan Energy within it was continuously depleted.
Then, Su Mo seemed to go mad.
