Yuyumamoru this context is somewhat actually true,
In reality, yes, there are cultivators, even at the present times, cultivation manuals disappeared in the public due to some rules set by ancient times, as what you said, The Era of Discord, it actually happened. Earth was once the most prominent realm in the universe, we are the center of prominence and we hold the power to rule all of the existence, the milky way was called Heavey Prayers of Existence, the Mercury Venus Mars Jupiter Saturn Uranus is its vassal state, but something happen, Era of Discord i wont elaborate, but in the history books of the records of the old, it says that the universe was engulfed in a all out war between races, be it the gods or the demons, they all fought for something that will lead them to higher realms though i say earth was the master of the universe at that time, unknown to the people, there existed a realm much higher than we do have, this realm was called by the people Tabulan Realm* fast forward, the earth was sealed from its former glory and all of the universe was sealed or destroyed, tho the scientific community saya that the universe is expanding, the truth is that the universe is repairing its lost prestige. And wanted a comeback.
The good news is, some of the old ancestor from that time and era is still alive, tho hibernating and repairing their spiritual bodies.
Like why cultivation manuals resources was sealed? It is to make the earth ready for the comeback, with the old and knowledgeable gone, who will make good use of the resources.
Theres still cultivators? Yes, though if it is scaled in a 100 million there is only 5-10, depending on a country, this few people are direct lineages from the past, and if u somewhat stumbled upon a manual or eat some fruit (u know what i mean) u better hide it till u have great power.
Additional: there is also weak cultivators who aren't part of the originala *direct lineages, but they're the weakest of the weak, dont feel almighty if u somewhat become powerful. Those direct lineages are deep hidden, not even those weakass cultivators knows of their existence, much less the government.
Is there a cultivator we know of today?
Yes, but those of the direct lineages, nope.
Btw, i am someone above God level. Above past Earth.
Clarification: God is a state, Evil is a state, Demon is a being, Human is a Being.
But somewhat Gods and Demons often get associated with each other, and that is a common mistake humans do.
