One moment, Luo Jing was at the brink of death after accidentally touching a power outlet while showering. The next, he was in the body of a man named Garen, with memories of a past he was never a part of flowing into his head. As he slowly gets used to the body of Garen, he begins to explore a planet beyond his own logical comprehension. His journey will see him go from surviving in a planet locked in the 20th century, to wielding secret techniques so powerful that they level cities overnight. However, his journey doesn’t end with Garen. Instead this is but the first of many bodies that Luo Jing will come to wield in his mystical journey between worlds.
The main trait of the Demon Lords was that they had many Soul Seed Rings. Soul Seed Rings structured this way, known as Soul Rings for short, could allow Demon Lords to reach their strongest state quickly and inconspicuously within a short period of time whenever they invaded a world.
But now Garen only had one Soul Ring, and according to his estimates, it was highly likely that powerful Demon Lords would have multiple Soul Rings. That way, once they entered a new universe with new rules, they would be able to integrate into the new power system there quickly, using the power of the Soul Rings to level up rapidly and eventually controlling the strongest power there.
That was the true terror of the Demon Lords. They were the real pillar in the fight against the Void Creatures.
