After Jiu Shen reached an agreement with the three Heavenly God Realm experts, he told them to gather everyone from the God Sword Region and bring them to the location of the Heavenly Sword Tower. The sword tower was yet to be finished but it should be done soon since Jiu Shen was planning to send the surviving members of the Shadow God Sect as free labor.
With the construction of the sword tower off of his mind, and the merge with the God Sword Region being handled by Yin Long and the others, Jiu Shen was now free to cultivate.
"You may leave now and prepare for the merging process. I will send one armored guard to inform the Heavenly Sword Tower about the details. Once you're done with everything, you can start cultivating here. You can also bring the elites of the God Sword Region to cultivate here."
