It wasn't drawn directly on the bodies of the zombies.
But what exactly was inside the bronze casket, and whether there were any zombies at all?
If so, what level of zombie were they?
Walking corpses, Iron Corpses...
Logically, what should follow would be Copper Corpses, Silver Corpses, and Golden Corpses...
Bronze coffin... could it be a Copper Corpse inside?
But judging from Lu Chengyun's tone, it didn't quite seem the case.
If it were a Copper Corpse, it should be quite powerful, perhaps with the cultivation of Foundation Establishment Late Stage.
Could Lu Chengyun, who was only at the Foundation Establishment Initial Stage, suppress a refined Copper Corpse?
If he couldn't suppress it and still attempted refining, wouldn't that be seeking death?
Those who are backfired by Corpse Refinement would definitely be devoured completely by the zombies, leaving no bones behind.
Lu Chengyun was shrewd; he surely wouldn't make such a foolish mistake...
But if it wasn't a Copper Corpse, then what type of corpse was it?
After much deliberation, Mo Hua suddenly realized a fundamental question:
He didn't even know the differences between Walking Corpses, Iron Corpses, Copper Corpses, Silver Corpses, and Golden Corpses...
Aside from hearing these names from his elder martial sister, he had absolutely no understanding of Corpse Refinement!
He was a complete layman.
Just like a cultivator who doesn't understand Formations pondering issues of Formation based on experience.
He was also just speculating on the categories of Corpse Refinement based on imagination.
It's very easy to assume things when a layman tries to consider an expert's problems.
Is there a distinction in quality among refined corpses?
Are gold, silver, copper, and iron grades, or types?
What are the effects and taboos of different corpses?
He understood all of this vaguely...
Dealing with ordinary Walking Corpses and Iron Corpses, his superficial knowledge might suffice.
But Lu Chengyun was clearly using a more "high-end" method of Corpse Refinement, and half-baked experience might not reveal anything...
And so Mo Hua was concerned again.
Practice brings true knowledge.
But he certainly couldn't just learn Corpse Refinement and then refine corpses himself just to understand these things…
Mo Hua thought about it and felt that it was impossible for him to actually refine corpses.
But it might be necessary to steal some books on Corpse Refinement from corpse cultivators and read them when he had the time, to understand both himself and the enemy.
The cultivation world is perilous.
Cultivators need to possess various kinds of knowledge to survive in the cultivation world.
Some things can be left undone, but not unknown.
Otherwise, once you face a "knowledge barrier," no matter how intelligent you are, it's useless, and you might even outwit yourself, sealing your own fate, dying without knowing how you died.
Mo Hua nodded slightly, then attempted to open the bronze coffin.
The bronze coffin was divided into an outer coffin and an inner casket; inside the casket was Corpse Refinement.
He would only open the coffin and not the casket; like Lu Chengyun, the risk should be minimal.
But Mo Hua had not anticipated that he wouldn't even be able to open the outer coffin.
The entire bronze coffin seemed to be sealed shut.
After several attempts, Mo Hua failed to open it and couldn't tell whether the bronze coffin was sealed by a Formation or locking mechanism.
Mo Hua sighed.
This trip yielded some gains, but they were less than he had hoped for.
He had thoroughly studied the Formation of Ten Thousand Corpses.
But as for what was offered on the altar or what was sealed in the bronze coffin, it was still unclear.
"It seems... I need to think of another way..."
Mo Hua's gaze shifted slightly as he silently mused.
