Mo Hua intended to deceive Lu Chengyun and Zhang Quan, sneaking into the sacrificial altar of the Corpse Formation. He had to get through two doors.
One was the door to the hall.
The other was that mural within the hall.
The hall's door was manageable, but the mural posed a significant challenge.
First of all, he didn't know what exactly were the hand seals and the incantations that Zhang Quan had used.
And Zhang Quan wouldn't disclose them.
Even if Zhang Quan were to tell him, Mo Hua wasn't certain that by simply imitating the process, the mural would actually open for him.
That zombie mural, like the Dry Ink Screen of the Corpse Walking Stronghold, must be some sort of door lock type of Spiritual Artifact.
If it was a Spiritual Artifact, then there must be a Formation inside.
This sort of Formation wasn't a Five Elements Formation and didn't fall within the scope of Formations that Mo Hua was proficient in.
Even if Mo Hua wanted to solve it, there was nowhere to start.
