[Dreamlands]
The first time they met in London City, Sally wanted to test Han Dong's strength, taking him to a hidden space designed as the 'World Sanctuary'.
They even accidentally alarmed the Nightmares King.
This time.
The two of them were very cautious, stealthily moving through the Dreamlands, finding a stone field not under the jurisdiction of any Old King.
The area was covered with stones of varying sizes.
Several dozen strangely shaped boulders pieced together into a peculiar formation... resulting in the area's gravity being several times that of other areas, even reaching ten times the normal gravity at its center.
However.
An intense battle was erupting on this field of broken stones.
Many Demons that lived here migrated away, frightened. Several clashes generated forces reaching the strength of a Mythic Body.
Layers of horizontal shockwaves continuously spread outwards, causing noticeable tremors dozens of kilometers away.
