Paranormal Border

A century-old monster knocking on the door has reappeared in Jiangcheng. The core rules are cruel and strange: knocking on the door three times marks life, and you will be hunted after closing the door. The mark can be transmitted infinitely through the "opening the door" action, sweeping the whole city like a plague. Liu Ji'an, an ordinary young man, was marked with a fatal mark because he accidentally opened the door. In order to break the situation, he accidentally entered the mysterious realm of Knocking Door - an infinite loop of wooden door corridors. Behind each door, there is an endless cycle of death for the victim. Gan Qingci, the man in charge of the Secret Bureau, used the power of the stasis trick to force his way into the realm to rescue them. The two worked side by side to explore the truth, only to discover that the serial deaths were not caused by the spooks spontaneously - the extremist organization Guixu Sect was secretly at work. They worshiped the spooks, deliberately spread the mark, and tried to use Liu Ji'an as a sacrifice to open up the original core of the Knocking Gate spooks. When the whole city fell into darkness, citizens closed their doors in fear, and the sound of knocking on the door resounded through the night sky again. Liu Ji'an relied on his super logic to deduce the rules of the monsters, and Gan Qingci used his magical power to fight against the believers and monsters. Only by breaking through the obstruction of the Guixu Sect and reaching the core of the origin can the two of them end the century-old curse. But they gradually discovered that the rules of Knocking on the Door were far from being as simple as they appeared. Behind the core of the origin, there was a shocking secret related to the survival of the monsters and mankind, and it was never an accident that Liu Ji'an was marked.
