A month ago, his health began to deteriorate, but the cause could not be found out. His body began to fail, and Shen Ling knew that he would not live much longer. The person closest to him betrayed him, so he took that person to death together. They said they died together, but in fact, he just didn't want to die alone, so he just used a back-up...
"By the time you read this letter, I should have been wiped out. The blood of 81 people is used as a guide for the forbidden curse. To attract the devil... I am the last sacrifice of this forbidden curse. I have no regrets, this world hurts me deeply... I don't want to live. If it succeeds, the whole world will be buried with me... If it fails, it doesn't matter. With these 80 people, I will not be alone on the road to hell..."
When Shen Ling woke up, what he saw was this letter written in "his" hand... Attracting the devil?... Was it actually the devil?
