Great Demons Walk the Earth

There are great demons in the world, beings rarely seen even once in ten thousand years. Their surging demonic power flows through their bones and blood, allowing them to soar through the skies and dive beneath the waters. They live long lives and never die. They know the future and possess every cultivation technique, secret manual, divine artifact, magical treasure, pill, and spirit stone in the world, making everyone under heaven clamor to get their hands on them. - Cen Yunkuo transmigrated into a book. It was a typical power fantasy about a male protagonist rising from the bottom. Cen Yunkuo was bound to a System. The System ordered him to take the protagonist in as a lackey, exploit him, abuse him, humiliate him, and serve as a devoted stepping stone on the protagonist's path to power. Cen Yunkuo understood. He had read plenty of stories from Qidian, and had dabbled in Jinjiang fiction too. He knew this routine inside and out. To keep the plot from turning into a Jinjiang story, Cen Yunkuo had a sudden inspiration. He decided to pick up eight or ten kids, with the protagonist among them, and treat them all equally. That way, nothing could go wrong. Who could have guessed that the plot would later go completely off the rails... Theme:
