[Future Cultivation Techniques] + [Great Beasts of the Classic of Mountains and Seas] + [Power Fantasy]
In the first year of the Martial Dao Era, spiritual qi revived. Animals could cultivate into demons by absorbing spiritual qi, and the great beasts from the Classic of Mountains and Seas gradually emerged from their seals, invading the human world.
In the hundredth year of the Martial Dao Era, martial arts were just taking off, and human warriors fought against demons.
In the two-hundredth year of the Martial Dao Era, humanity was in decline, and demons kept seizing more and more territory.
In the three-hundredth year of the Martial Dao Era, Jiang Lingyu transmigrated into this world, only to find himself in the body of a six-year-old. He had a System, but it lost contact with him. It wasn't until he turned eighteen that the System got back in touch, and it was now a hundred years in the future.
“A body-tempering technique from a hundred years in the future, improved over the course of a century, is ten times as effective as the one you have now!”
“A martial arts breathing technique from a hundred years in the future...”
“A body-refining medicine formula from a hundred years in the future...”
“Combat techniques from a hundred years in the future...”
“A hundred years from now, countless great beasts from the Classic of Mountains and Seas will emerge from the Realm of Mountains and Seas, bringing humanity to the brink of annihilation.”
“Since I can't stop the ferocious beasts of the Realm of Mountains and Seas from invading, I'll lay the groundwork a century in advance and eliminate the great beasts.”
“I, Jiang Lingyu, am humanity's only hope.”
Sigh, it was a bit of a waste of time. The protagonist's initial plot of killing demons to obtain cultivation techniques, then practicing those techniques, and the martial arts exam and fighting with classmates felt like too much filler. I didn't read much after that; I guess he went to university.
