Shattered Star Valley, Middle Layer.
Spatial fragments drifted slowly all around. At the narrowest points, only one person could pass sideways.
Li Yuan threaded his way through the fragments, running Void Domain Profound Mastery at full strength. The spatial structure within six hundred zhang appeared in his sea of consciousness. This time, he went deeper than before.
East of the Middle Layer lay a dense belt of rifts. Dozens of fissures crisscrossed it, some cutting through the edges of fragments, others hanging in midair. The longest stretched more than twenty zhang. The spatial walls between them were deeply unstable. Now and then, a new fissure tore open from nowhere, only to heal itself several breaths later.
Li Yuan stopped at the edge.
This was just the place to hone the Spatial Restriction Technique.
A fissure was expanding rapidly, its edges carrying tremendous cutting force. Li Yuan closed his right hand. The Spatial Restriction Technique landed across the fissure's middle, forcibly arresting its expansion.
The spatial torsion at the fissure's edges collided with the restraining force, sending out a muffled hum. After several breaths of stalemate, the fissure stopped expanding.
Thirty breaths later, Li Yuan released the restriction and turned to the next fissure.
One after another.
The spatial fluctuations in Shattered Star Valley's Middle Layer were several times stronger than those at its outskirts. Spatial Imprisonment Technique had to contend not only with the expanding fissures, but also with interference from the surrounding spatial walls. Its area of effect began at ten zhang, then edged outward with each repeated casting.
Eleven zhang, thirteen zhang, thirteen zhang.
Every additional zhang drove up the spirit power cost. Fortunately, after Talisman Domain Spatial Stabilization became permanent, spatial stabilization spells consumed twenty percent less. The spirit power saved went straight into expanding the restriction's
