As the Supreme of the Demonic Path, I Possessed My Blue Star Hometown Friend from the Start

My name is Li Changsheng, and I am the only Great Emperor on the Tianxuan Continent. The Heavenly Dao set a trap for me, and with no System to help, I ultimately fell. Before my death, however, I made a prediction and discovered that another fellow countryman would arrive in ten thousand years. So I hid my soul in the Forbidden Land and spread the rumor that it held the inheritance of the Demon Emperor, and that whoever claimed it could take his place and become the strongest. Over the past ten thousand years, countless geniuses and powerful figures came seeking it. But none of them were the one I was waiting for. With no other choice, I remained in hiding, waiting for someone destined to find me. … My name is Li Changsheng, and I am the direct disciple of the Palace Master of the Heavenly Secrets Palace. I heard that whoever finds and obtains the Demon Emperor’s inheritance can take his place and become the strongest. So the moment the inheritance appeared, I came. … Answer three questions. Get them all right, and you can claim the inheritance. Get even one wrong, and you’ll be killed on the spot? Sounds interesting. But my Heavenly Secrets Palace has received the Heavenly Dao’s gift: the power to divine the secrets of fate. Whatever the questions are, bring them on. … What do you mean, “If the change is odd, the number stays the same; if it’s even, the number changes”? What do you mean, “Palace Jade Liquor”? What do you mean, “How much does the shirt cost”? … Just when I thought I could bring back the Demon Emperor’s reign over the entire continent and become the strongest, his voice rang in my mind: “You passed the inheritance trial. Your body will receive the supreme Demon Emperor’s primordial spirit!” Me: My body gets Genshin Impact? Isn’t that damn possession? … Demon Emperor: “Wonderful, you got them all right. I’ve been waiting for you, fellow countryman!”
