Within the enclosed space where Zhang Zhe and Xia Yingbing now stood, apart from the massive array before them spinning at full speed, the energy in the space had not changed much.
But if the two of them had been in the original underground cavern at this moment, they would have been stunned by the sight before them.
At this moment, throughout the underground cavern where the three of them had initially entered—whether in the passageways or the several enormous underground chambers—the tremendous energy that had once lain peacefully in the space had become like a raging river and sea.
The violent energy surged wildly, pouring frenziedly into the restrictions on the surrounding stone walls.
Anyone standing within it would inevitably be swept into that violent energy. As the energy erupted into a frenzy, the entire underground space became suffused with a strange restraining force that even a peak Integration stage cultivator would find difficult to withstand.
It was as though the entire underground space had been placed inside a massive array. Lines of nearly imperceptible runes shot and darted through the air, guiding the tremendous energy within it into the glimmering restrictions on the cavern walls.
These runes showed no obvious might. But if they truly touched the body of a cultivator or demon beast containing energy fluctuations, no one could know what terrifying attack they might unleash.
Time slowly passed. Within several underground estates, each dozens of li in circumference and hundreds of zhang high, the originally immense demonic and spiritual energy began to rapidly deplete under the frenzied absorption of the stone-wall restrictions.
One day, two days, three days...
With the two late Integration stage cultivators, Zhang Zhe and Xia Yingbing, wearing terrified expressions and never relaxing for even an instant, time rapidly slipped away.
