Getting Rich Through My Best Friend [Crossover]

When that clueless Golden Boy said he was going to look for the elixir of immortality, I knew I was about to die. After completing a lifetime as Enkidu and finishing all of the System's missions, I calmly returned to my original body. As Uchiha Itachi, I wanted nothing more than to live an uneventful life. The very night I returned, someone showed up and asked if I was ready to kill my father, mother, and entire family. I replied solemnly, "I'm ready." Then I turned around and told my bargain-bin dad about the joke. My dad was such a coward that he moved the whole clan that very night. Now I'm the richest person in the Land of Fields. I'm lazy, but I can open my best friend Golden Boy's Gate of Babylon whenever I want. Fine wine, gold, silver, treasures: I can take whatever I like! My only problem is that strange people keep showing up around me. For instance, my younger brother Sasuke, whom I've trained into obedience by beating him once a day, suddenly charged at me and said he was going to kill me. Has he lost his mind? I have to educate my little brother right away. But I really want to ask Mom: how many Sasukes did you give birth to? This one is older than me, has one arm missing, and still has the nerve to cry and call me big brother? Later, a goddess said she was going to destroy the world. I opened the Gate of Babylon to take out the divine weapon, the Chain of Heaven, but Golden Boy came out holding the other end of the chain... Thinking about all the things I've swiped from his treasury over the years, I started to panic... A hilarious, absurd comedy about the chaotic adventures that follow the return of Demon King Uchiha Itachi, with the characters wildly out of character. Theme: Life is full of endless possibilities
