Blood Gray Gold

In the year 2000 of the Era of Terra, humans first discovered the existence of "Limbo" and the "Gatekeeper" organization. "Limbo" is a gap space that can be entered from the real world. Humans only need to stay in "Limbo" for a period of time. There is a probability of obtaining supernatural powers. Not only that, the ashes turned into the corpses of the special creatures "demons" in "Limbo Hell" after their death have unimaginable energy. Through this ashes as a medium, and with a certain amount of knowledge, humans can use "magic". The "gatekeepers" have mastered the methods of entering "Limbo" and the use of ashes since ancient times. Now that "Lingbo" has been made public, the gatekeepers saw that they could not keep the secret, so they began to cooperate with the government, hoping that it could properly protect Limbo. They shared His own knowledge about magic, demons, and Limbo, but somehow this knowledge was spread. Therefore, faced with the ashes of demons that could drive magic or be sold at extremely high prices, the world began to explore Limbo, known as the Gold Rush Era. But the gold diggers soon discovered that what they had to face was not the devil, but the guns of their colleagues. In addition, the "gatekeepers" had already lost knowledge about the origin of "Limbo" over the past millennium. Who knew that there was gold behind Limbo? Or the eternal door to darkness?
