He observed everything from the shadows so he was able to have the initiative and was less exposed to danger.

The sealing skill in Yu Yunxian's body was profound. It wasn't something an ordinary person could make. Wang Teng could only replicate it because he was a rune grandmaster and his spiritual power was immense.
At this moment, he was fully focused, not daring to relax even the slightest bit. He engraved the seal bit by bit with utmost caution.
When he was carving the runes, he had to constantly be on guard against the violent surges of dark Force.
After all, the dark Force wouldn't sit still and allow him to seal it without resisting.
