I Play the Cultivation System in the Grand Line

On the first day of vacation, a game appears on your phone out of thin air. The icon is a skull and the name is "Let's Play the Development System" You don't take it seriously at first, until you find out that this game takes up 100G of memory, and the uninstall button won't move even if you press it badly. It will reappear the next day after restarting, flashing, or even changing to a new phone. You cursed and opened this game with the mentality of "Let's see what kind of virus it is." Welcome to the Great Route Development Game! [Here you can cultivate, collect, accompany, bond, and even change some established destiny! [The first draw is free, please draw your first cub] You look at the Q-version villains in the free card pool, each with a different personality, appearance and ability. Fingertips hovering over the "Extract" button. Bite! Golden legend! The screen was engulfed in dazzling golden light. When the light dissipated, a Q-version villain appeared in the center of the screen - a villain wearing a straw hat, round eyes, a body made of rubber that could stretch half a meter, and he stuffed everything into his mouth. [Name: Monkey D. Luffy] [Rarity: UR] [Current status: infancy] OS: ... It seems, quite cute. You watch the Q version of the little man on the screen running, jumping, and chasing butterflies all over the mountain. The food you throw casually, he thinks it is falling from the sky. When you poke his straw hat at night, he rubs his head and thinks it is the wind. When you tuck him in, he thinks he is dreaming. But gradually, Luffy began to feel something was wrong. "Why does meat appear next to me every time I'm hungry?" "Why does it always feel like there is an invisible umbrella above my head when it rains?" "Why... I always feel like someone is looking at me?" Luffy went from doubting to testing, and then one night, you tucked him in through the screen, and he suddenly opened his round eyes and asked in confusion: "Who are you?" The real change occurs on the day when the favorability level increases. The screen suddenly lights up with a new prompt: [The favorability level has been improved, and the conversation function has been unlocked] You typed tentatively and sent the first message: "Hello?" So Luffy started talking to the air every day, asking what is your name? Where are you? Will you always be there? Until one day, the screen suddenly exploded with a golden light. [Luffy's bond level reaches the standard! [Congratulations on unlocking the new card pool! You can now draw more Zaizai! [Free lottery number × 1] The second Q-version villain is a somewhat lonely villain with long earlobes, blond hair, and a crackling electric spark in his hand. His name is Enelu. The third Q-version villain is a villain with messy red hair like seaweed, a gentle smile on his face, and a smile that makes people unable to take their eyes away. His name is Shanks. As the favorability level continues to increase, new card pools are constantly unlocked. You draw one Q-version villain after another, filling up the picture book. You spent the entire holiday watching them grow from Q-version villains into teenagers. When the favorability level is at full level, what pops up in the dialog box is not a thank you, but a confession to you: "I bet this arm on a new era... But the rest, I want to use it to hold you." "If possible, do you want to be the only mistress of the sanctuary?" "I like you the most, more than anyone else." You looked at their serious looks on the screen and didn't take their confession to heart, thinking that it was just a line set by the game. When the holiday was about to end, several system notifications popped up on the APP: [The ultimate reward of the system has been distributed] [Open two-way channel] [Welcome to the Great Route] Before you could react, your vision suddenly went dark. When you open your eyes again, you are lying on a strange white beach, with the tropical sun above your head, and nothing around but the vast sea, a deserted island. And in your hand, you are still holding the phone tightly, the screen is on, and a line of notification pops up from the APP: [Current coordinates: An unknown desert island in the East China Sea] Welcome to the Great Route! *Attention and demining: ① Otome refers to the second person ②The heartthrob Mary Sue ooc ③The development period may be very long, not just the three above Concept: Another story in the parallel world of One Piece
