For a time, Zou Feng completely gave up on cultivating in the Demon Suppression Tower.
Instead, he holed himself up in the Hall of Combat, relentlessly challenging Liu Chenyu's Mind Body.
To get the most out of each challenge, he would intentionally prolong every fight.
Even when he could have secured a swift victory, Zou Feng would deliberately hold back to better acclimate himself to Liu Chenyu's illusions and Charm Technique.
After more than ten days of this, Zou Feng had thoroughly analyzed every aspect of Liu Chenyu as she was in the Spiritual Energy Realm.
He also developed a considerable immunity to her illusions and Charm Technique.
For instance, even when Liu Chenyu cast an illusion of herself completely bared before him, Zou Feng remained utterly calm and unfazed.
Through this repeated training, he could even instantly enter a "sage-like state" to nullify her charms.
