Global Ghostization: I Have a Billion Evil Spirits in My Body

My name is Zhu Yan, and I am recognized as a waste by the Luocheng Ghost Control University, with a spiritual power value of only five. The whole school was laughing at me, until the day the tester exploded in front of me. A deep voice sounded from inside me: "I'm bored. Let these ants see what a real ghost is." There are a billion evil spirits sealed in my body. They have been sleeping for thirteen years, and have been inside me since the high fever when I was six years old. Now, they are starting to wake up. The first one to wake up was Xing, an S-class evil spirit who was violent and bloodthirsty. The second one is Ying, a girl who has been waiting in the coffin for three thousand years, with blood and tears hanging from her eyes. She asked me if I would leave her, and I said never. She threw herself into my arms and cried the whole night. But the Ghost Palace found me. They told me that my birth was an experiment from beginning to end - I was the key to the ghost prison, and what was sealed in my body was not only a billion evil spirits, but also the souls of ten ghost emperors. What took my breath away even more was the news. I also have a twin sister named Zhu Yue. He was taken away by the Ghost Palace eighteen years ago and trained into the coldest weapon. She wanted to kill me, but she didn't know that I was her brother. From the trash of the whole school to the lord of the ghost prison, from being alone to having a family to return to. I want to take my sister back, I want to wake up all the billion evil spirits, I want to stand in front of the Ghost Emperor and tell him—— Don't bully a loser. You never know what price he will pay you back.
