The process of merging the two realms was initially fast but then slowed down, and it didn't last as long as Qing Muling had imagined.

After more than three months, the spatial rift had expanded to the size of several hundred great Immortal Domains, equivalent to one-tenth of the Great Void.

By now, the concentration of spiritual energy and Dao Rhyme in the entire Great Void had undergone a qualitative change and was still slowly increasing.

For the cultivators of the upper realm, the concentration of spiritual energy in the entire world had temporarily decreased. However, due to the larger size of the upper realm, this change was not very noticeable and was expected to recover after some time.
