Problems and the Development of the Internal Grotto-Heaven

In a high-intensity testing laboratory somewhere on the Purgatory Sulfur Plane, Benjamin frowned deeply as he remotely controlled a newly crafted Rune Artifact for a power test.

With a thought, he controlled the disc-shaped Wizard Artifact hovering in midair, roughly thirty centimeters in diameter.

The artifact's surface was densely engraved with entirely new composite patterns that fused Cultivation talismans and wizard runes. At its center sat a fist-sized energy-focusing crystal.

Hum...

Following a mental command, the focusing crystal at the center of the disc suddenly lit up with blinding white light.

A projectile of energy composed purely of elements was launched, trailing a long tail as it shot toward the "target zone" in the distance, expanded through spatial folding technology.

The entire Testing Ground had undergone special spatial folding. From the outside, it was merely a room a hundred meters square, but its actual interior depth reached an astonishing five hundred kilometers.

The light projectile flew through the air for roughly three seconds. This speed was not particularly fast in real combat, but it was sufficient in a testing environment.

Immediately afterward, a massive flash rose from the distant target zone, so dazzling that even through the protective barrier, one had to squint.

There was no explosion. With the energy shields isolating the space, no sound could travel through.

What replaced it was a more fundamental shock: the multiple layers of energy barriers arranged throughout the Testing Ground rippled and warped violently like curtains of water struck by an invisible giant hammer, letting out an overburdened hum.

Even with the "distance buffer" provided by spatial folding, the powerful shockwaves continued to reverberate and stack within the Testing Ground, making the barriers fluctuate more and more violently, as if they might collapse at any moment.

Benjamin paid no attention to the
