Naruto Kills Demigods at the Beginning

He traveled through time as a Saiyan and was on his way to carry out a mission to destroy life on the planet. Su Yu: "It's none of my business." Stepping out of the egg-shaped spaceship, I found that the planet that needed to be conquered turned out to be Naruto's world. A powerful demigod? That's not why you treat me like a weakling, right? Let me first tell you something that comes from my heart. "Ding~ Congratulations to the host, you have obtained the Big Brother system." "Ding~ The little girl's wish has been detected and the dream come true plan has been triggered." "Choose one, say it confidently: this wish is too simple, the reward: reincarnation." "Choice two, sorry sister, we can't realize this wish, can we change it? Reward: 100 points of combat power." In order not to disappoint his little sister, Su Yu chose one. Please, he doesn't take it lightly with a mere hundred points of combat power. —— Fifteen years later... Su Yu stood in the sky, with countless familiar characters from the Naruto world behind him. Naruto was the first to bear the brunt and fired an energy bomb at the spaceship descending from the sky! "Damn it! Su Yu betrayed the Saiyans!" Note: This is a story about becoming stronger after accepting a younger brother. The content is light-hearted because he is so invincible. The title of the book is also called: "I am a dream-realizing master walking in the world." The introduction is weak, please read the text.
