Wanderer of the Deep

A car accident left Mao Yu "dead" for four minutes and twenty-three seconds. After waking up, he began to see "unclean" things - black cats, little girls in red, giant strange birds... They came from the "deep world" that overlapped with reality, and he became the only "connector" who could see through the two worlds. What's even more frightening is that the "guardian" of the deep world comes to his door and gives him three days to make a choice: accept the mark and become the agent, or escape, or - die. Caught between two worlds, he has nowhere to escape.
