Song Shuhang didn't want to deceive the Great Northern Emperor. If the "path of the Heavenly City" that the Great Northern Emperor and the others moved to the fragment of the Heavenly City in his Inner World was affected, their plans might fall apart, and Shuhang would feel uneasy.
"Is that a problem?" The Great Northern Emperor asked, noticing Shuhang's troubled expression.
"Senior Beifang, it's not an issue of trust. I'd gladly lend you my Inner World. However, if the fragment of the Heavenly City enters, I might lose something important," Shuhang explained.
"Lose something? Are you worried that the fragment won't be able to move out once fused with your Inner World? You don't have to worry about that," the Great Northern Emperor reassured. "Once our plan is completed, you can keep that part of the fragment. Only a few key fragments are needed for the Heavenly Court, and you can keep an eye on those."
