Chapter 167: Slaying the Flesh with the Blade, Cutting the Soul with the Heart_2

Of course, Lu Ran didn't just practice non-stop.

He trained on multiple fronts.

After swinging his sword a few times with no effect, he took out the Soul Suppressing Stone and slapped the King of Sudden Death's soul out.

Then, through Psychic Sensing, he perceived the different sensations the King of Sudden Death experienced when being attacked by him versus being attacked by the Soul Suppressing Stone.

Such comparative practice deepened Lu Ran's understanding of soul damage.

Of course, it didn't just stop there.

After all, even though the knife caused no damage, it still annoyed the King of Sudden Death after constant chopping.

At such times, Lu Ran would put down the knife and release flames, attacking the King of Sudden Death with a Flame Spirit Attack.

Similarly, only when the King of Sudden Death could feel its soul being scorched, rather than its body, did Lu Ran make progress, turning ordinary flames, in combination with Psychic Sensing, into soulfire.

Just like that.
