Xiao Mu's harvest wasn't abundant, but it wasn't meager either. He acquired only three substantial objects, including Lei Gong's Thunderous Attack, Thunderbolt Hammer, and Eight Tribulations Silver Wind Boots.
Besides that, there were invisible gains, including another Authority Technique from Tai Cang City God, one that manifests a "Longevity" character and completely heals one's injuries when used.
This newly-discovered City God's Authority Technique interested Xiao Mu more than the three treasures of the Thunder Lord.
First, he reformulated the three treasures of the Thunder Lord using the King's Authority Sealing Technique, then Xiao Mu began to strategize the next steps in his advancement.
In this battle, his own Realm was too low. Otherwise, he could have gained more benefits, and enhancing the authority of the Seal of the Heavenly Emperor would help him strip more treasures.
