Chapter 637: Mortal World, Refining the Heart

"If the Immortal Spirit World really discovers the location of our Heavenly Mystic World, I'm afraid they will send an army to suppress us, right?"

Yan Zhenqing had cultivated for countless years and had also participated in external battles. As the assistant head of the Imperial City Academy, he was not unfamiliar with the layout outside the Heavenly Mystic Realm.

Han Muye didn't know much about the foundation of the Heaven Mystic Realm, so he just listened quietly.

"That's right, so Senior Brother Wen suppressed the outer realm and activated the power of the array." Marquis Wu's eyes flickered as he turned to look at Han Muye.

"If you hadn't distracted the Immortal Spirit World and the Spiritual Armored Demon Clan with the Desolate Wilderness last time and allowed Senior Brother Wen to suppress many powerful figures of the Spiritual Armored Demon Clan, I'm afraid we would have retreated more than 30 million miles in this battle."
