Lin Huang was a 15-year old boy from Earth, on a path to live his life in a world full of monsters. With his younger sister in his care, and given only 91 days to live, the odds were not in his favor at all... That is until, he killed a vicious vampire, purely by accident. With a twist in his tale, his life was changed completely. As he fought his way through this world with the help of his troops made of men and monsters, the boy sets his sights on a much larger ambition of becoming the greatest monster hunter in the world!
"This room in the underground is exclusively for people to take care of those who they've deceived. When people are lured here, they'll be beaten until they're unconscious, then their clothes and Emperor's Heart Ring will be taken away. They'll be sedated, cleansed and sterilized. Eventually, they'll be given a Life Power inhibitor shot and put into custom-made cages as test subjects.
"The people who are captured can't fight back at all since they'll be given a Life Power inhibitor shot every day. Moreover, the cages are made of monster bones and metal. Even an imperial-level powerhouse could hardly break it.
"The stubborn ones who fight back will be killed in front of the rest. The rest of them will feel numb eventually and give up fighting, accepting their fate of being test subjects."
Lin Huang finally found out the middle-aged man's real purpose after getting Bloody to read his mind.
