In the boundless darkness, Gu Qing Shan was flying at full speed.
Occasionally, to speed himself up, he would use [Ground Shrink] to travel through a large distance.
--------but he didn't use it too much.
Earlier, when he unleashed the three strikes of the Asura Divine Skill, both his body and spirit were greatly drained, and hadn't been fully recovered.
Everything ahead was unknown, and there was a very real danger of running into monsters, so Gu Qing Shan was trying to conserve his strength.
In the darkness, he kept his inner sight released at all times but still couldn't feel anything apart from the huge wall on top, whose border he couldn't fathom.
After a bit of thought, Gu Qing Shan decided to fly close to the ceiling.
Occasionally, he would leave marks on the ceiling with his sword as well as arranging some warp formations.
This was done in order to leave bread crumbs for him to find his way back whenever necessary.
