Su Nan left the ancient temple.
Since he was sure there was no danger outside, he didn't need to continue using his foreknowledge in the temple.
The distance from the temple to the deep pit was too far, and continuing to use foreknowledge here would be a waste of his ability.
Knowing there was no danger, Su Nan moved quickly, and in just over ten minutes, he arrived near the deep pit he had seen in his foreknowledge. Only then did he continue to use his ability.
[You know, once you enter the deep pit, an unknown entity will pull your Divine Soul out, so you plan to directly use Across the Heavens Shift to reach the bottom of the pit.]
[Using Across the Heavens Shift, your avatar instantly arrives at a position three thousand meters inside the deep pit. To your surprise, you don't directly arrive at the bottom but are caught in the process of falling.]
