No one knew—not even Cao Jin himself—that the Sky-reaching Sword Dao Li Yun had taught him had not only departed completely from the Cao Family's original Sky-reaching Sword Dao, but had also taken on a faint trace of a concept.
That concept was the Sky-reaching Concept.
It turned the great Dao of heaven and earth into sword Dao. Once the concept was perfected, a single sword strike would encompass the great Dao of heaven and earth.
It was an exceedingly domineering concept.
But concepts were elusive.
Cao Jin's cultivation was still too low for him to fully grasp its essence.
He thought it was merely a sword Dao technique.
So he practiced it step by step.
Even so, after mastering the Sky-reaching Sword, he had inevitably taken on a trace of that concept.
When he sensed danger descending, he instinctively slashed out, releasing that subtle concept with his sword.
And at that moment—
The Sky-reaching Sword cut across the sky above the Shen Residence, like a streak of peerless brilliance illuminating the entire Shen Family.
Beneath that brilliance, the great Dao of heaven and earth in the surrounding area was revealed.
A baleful figure that had been hidden from sight was illuminated as well. Radiating the terrifying aura of a Saint Gold Divine Lord, he had been slipping silently toward the Shen Family's back garden.
Suddenly exposed by the Sky-reaching Sword, he stood there dumbfounded.
In fact, he had noticed Cao Jin long ago. He simply had not spared him a glance. From beginning to end, he had only one target: Li Yun, a fellow Saint Gold Divine Lord.
To avoid alerting Li Yun, he had not even considered touching Cao Jin.
Never in his wildest dreams had he expected Cao Jin to detect him, much less react so swiftly
