I actually got it!
Even as a regressor, Gu Qing Shan was feeling exhilarated right now.
A Divine Skill!
[Shadow Shift]!
Suddenly, he threw both Chao Yin Sword and the Earth Sword forward.
Both swords flew side by side.
Suddenly, Chao Yin Sword disappeared, replaced by Gu Qing Shan.
He grabbed the Earth Sword, then disappeared again.
One second later, he reappeared where he originally was, grabbing Chao Yin Sword.
Divine Skill, [Shadow Shift]!
Divine Skill, [Ground Shrink]!
In the blink of an eye, both swords were in his hand again, as if Gu Qing Shan hadn't moved at all.
Gu Qing Shan took out a formation plate and arranged a Wind Spirit formation, the only formation he knows how to arrange.
He then threw the formation plate again, lodging into a rock in front.
The formation plate started to shine, forming an alarm formation around the rock.
