I Got Shot in the Head While Drinking, You Said I Was a Suspect

I am Lin Xi, an officially certified "Escape Man". My job is to sneak into the chaotic consciousness of the deceased and find the real murderer in the dream. This time the mission is "Viking Tavern Headless Case". The "murderous intent" collected at the scene was eerily calm - not one of them was afraid of death. However—— My team leader wanted me to die. He said, "Lin Xi, find the murderer, otherwise your consciousness will be trapped in a dream forever." My investigator wanted me dead. He said, "Lin Xi, you have an abnormal frequency and are a potential criminal that I can arrest at any time." Me: "???" Now, I stand in front of the endless high wall of yellow sand. Or, find the person behind the murder and uncover the secret of this murder. Or, in this murderous intention, real death will come.
