The second image shows Li Mu in a dark valley, traveling alone in the air, seemingly being chased by some dangerous creature, or perhaps trying to dive into the darkness of the valley, escaping from something. The image is somewhat dark and blurry.
The third image is quite grand, with shadow battle beasts all over the place, the sky filled with densely packed warships and sword-controlling cultivators, as if a century-long war is erupting. Li Mu is in the clouds, looking down from above, observing the battlefield without intervening.
The fourth image makes Li Mu a bit worried. In the first three images, he wasn't deeply involved, appearing as if he could advance or retreat freely.
