Cultivators' division of eras was actually quite rough; before the establishment of the Three Divine Dynasties, it belonged to the Ancient Era.
And the Ancient Era was already considered the very beginning by the vast majority—it was a time of unparalleled chaos, which only began to have order with the successive establishment of the Three Divine Dynasties.
However, Yu Ziqing knew that before the Ancient Era, there was a time when deities ruled the world, an age where people were treated like pigs and dogs.
Yet now, there were almost no legends left about the era of deities.
The only connection to the era of deities still present was the Earth Deities enfeoffed by the Divine Dynasty.
Unfortunately, these Earth Deities were not even close in rank to the deities of the deities' era.
Calculating it, from the start of the Three Divine Dynasties to now, even considering the lifespan of those top strong individuals, not many years have passed.
Some cultivators might have practiced Dharma Methods that significantly extended their lifespan, and if their Realm was high enough, they could have lived from the Ancient Era to the present.
Thus, for Dao Cultivators who pursued knowledge tirelessly, they were never worried about the lack of the unknown; their unknowns only increased, giving them plenty to research.
At first, they only knew about Devils, then discovered that among Devils, there were Heavenly Demons, and even developed spells like the Heavenly Devil True Name Spell targeted against them.
Nowadays, they had discovered another type of special Devil among Devils, the Yin Devil, which never encountered powerful cultivators.
Wen Lingyou's face was as calm as water. With just a slight comparison to historical records, he could confirm with 100% certainty that the event of the Black Tapir's extinction thousands of years ago was a conspiracy.
The question Yu Ziqing had asked also could now be confirmed.
No evidence was needed; one only needed to look at the result to know.
Moreover, Yu Ziqing was more certain than Wen Lingyou that the conspiracy was definitely not orchestrated by the Yin Devils.
The unique nature of the Yin Devils completely severed them from all powerful cultivators, as if they were not in the same world.
The Yin Devil Domain had low threat yet strong concealment; strong cultivators couldn't sense the Yin Devil Domain, nor would Yin Devils include powerful ones in it, ensuring they could never encounter each other.
Therefore, events of that year might have involved the Yin Devils sowing seeds, but those who fanned the flames or led people to destroy the Black Tapir were definitely not Yin Devils.
Too much time had passed, and the Dao Cultivator who had acted as a fuse was already dead with no evidence to prove it.
Trying to investigate matters from thousands of years ago, especially those involving the Langya Institute from that time, was fundamentally impossible.
Wen Lingyou clearly understood this. At most, after going back, he could look into old records to see if there were some unnoticed records from that time.
According to the traditions of the Lihuo Institute, there should be detailed records of any event; though they might not have been useful at the time, they might be in the future.
At that moment, Wen Lingyou thought of more; since there were special and bizarre Devils like the Yin Devils, should the previously encountered Devils also be classified separately?
Besides these, were there even more types of hidden Devils?
Especially in that Abyss full of Devils, were there more unknown entities?
From the matter of the Black Tapir, it could also be inferred that in earlier years, when the human race transitioned from chaos to order and began to accept and assimilate with the Alien Clan, the extinct races or beings might have also perished due to conspiracies similar to that of the Black Tapir.
With just a slight thought, Wen Lingyou was chilled to the bone.
He had even thought of several other special beings whose extinction seemed similar to that of the Black Tapir.
If each type of extinct being corresponded to a certain type of Devil,
Wen Lingyou dared not think further; the more he thought about it, the more terrifying it became.
He suddenly understood why Yu Ziqing asked whether they had gone to Almsgive Hungry Ghosts, to eliminate Devil Thought.
Why, knowing about the Yin Devils, did he not mention it, but only provided a clue for them to investigate themselves?
If it were him, he wouldn't dare either.
If this matter blew up, stirring waves, causing those hidden Devils to suddenly decide not to hide anymore and directly reveal themselves.
If those Devils had already gathered enough power, stirring up trouble would be akin to directly waging war.
With the terrifying concealment abilities of those Devils, could they bear the huge losses when war inevitably broke out, and how many people would die?
Even if they could win the war, if all the mortals and low-tier cultivators were wiped out, what use would the remaining masters have?
Countless thoughts flashed rapidly through Wen Lingyou's mind.
He bowed with his hands.
"Thank you for Young Master Qing's caution."
Yu Ziqing had several question marks floating above his head.
It was widely spread outside, and these grand figures among Dao Cultivators had very quick thought processes, and their trains of thought were so wild their disciples couldn't keep up. Now he finally understood a little.
"Senior, do we need to kill that Yin Devil?"
"No, before it realizes we have discovered it, I want to find a way to study it; the Yin Devil's danger is not high, making it suitable as a starting point."
"Alright, senior, be careful."
The danger wasn't very high; it hadn't been before, and now with the arrival of the hungry ghosts, after Almsgiving, the danger was even lower.
In the future, it could possibly be utilized as a tool to train the mindset of low-tier disciples, but only if it could be controlled. If it couldn't be controlled, it was best to slice it.
