The Vision of The Divine Walls

When the Undead finished drawing a door on the wall, the moon was high above the Ancient City Gate in the clear sky. 

The moon shone brightly like a white curtain. The moonlight reflected the ordinary plains outside the Ancient City Gate. But when light fell on the area inside the Ancient City Gate, they were greeted with a completely different sight than what they had seen in the day. 

Under the reflection of the moonlight, many buildings from the ancient era appeared inside the Ancient City Gate. Although the streets, people, and soldiers were just phantoms, Mo Fan and his group felt as if they had traveled back in time. Their surroundings were crowded, lively, and vivid.

"Come, let's go to the Sky Observing City once more." The Undead invited the crowd out from the Ancient City Gate, gesturing for them to walk out under the gate, and then walk in through the gate again.
