On the ground, the Eternal Joy Immortal Realm Invading Army and the Holy Wind Sect were locked in a deadly battle. Although the Holy Wind Sect's members were weaker, they had the one-time use of Sound Demon One as a supplement, along with various special modern technological weapons. They fought admirably against the Invading Army, with both sides suffering casualties.
However, overall, the Holy Wind Sect was still at a disadvantage. Even with the Combined Attack Formation and other methods to make up for their lack of strength, the gap with the Eternal Joy Immortal Realm was simply too vast. As time passed, the Holy Wind Sect's situation worsened each day, causing great anxiety among its members. If this continued, the Immortal-Slaying Secret Realm wouldn't hold for much longer.
