The moment he entered the Tongtian Tower, the Azure Dragon's Horn he carried with him once again dispersed into white light, enveloping Jiang Wang.
There was no one around.
Within the Tongtian Tower, each person once again faced their own independent space.
The first thing Jiang Wang thought of was that he no longer had to consider the threat from Wang Yiwu, at least for the time being. Then, he relaxed his mind and plunged into the boundless and unrestrained world within.
The human body has four seas.
The spine is the first sea.
Enclosed within the spine, the Dao Veins nourish the Path Origin and accumulate provisions.
Before ascending the dragon, it is in a state of overlapping and merging with the Sea of the Spine.
As such, the Sea of the Spine at this stage can also be seen as Tongtian Palace itself.
Tongtian Palace is another name for the Dao Veins.
