Players are coming, fortunately I have a time travel simulator

On July 1516, 7, you were adrift on the vast ocean, clinging to nothing but a piece of driftwood. You possessed nothing, no food or drink, save for a ring on your finger. You made no attempt to communicate with Roger, knowing he wouldn't wake up unless he ate a lot. Upon examination, you discovered that your Conqueror's Haki and Observation Haki were still present, though weakened. Only your Armament Haki needed a complete overhaul, and you speculated that the former were based on the mind, while the latter was based on the body.

On July 1516, 7, you began gathering food and practicing your Armament Haki by swimming. While your Observation Haki's range wasn't very wide, it pinpointed the location of a distant island. While swimming, you began to ponder what you wanted to do. During your previous journey, you experienced firsthand the darkness of the Celestial Dragons. Perhaps finding the great treasure and overthrowing their rule would be a good goal. (Chaos Tendency +2)

On July 1516, 7, after two days of travel, you arrived at the island. Sure enough, it was the same Windmill Island. The villagers were welcoming, and as expected, you met that unlovable kid again! It was you, King Luffy. You've been quite well-informed, but it was the first time you'd seen someone using dried feces as a hidden weapon. It was completely unsportsmanlike, especially since they were the protagonists of a manga. It was disillusioning. According to King Luffy, he was defending Windmill Village—with feces? You only regretted not having a camera to record his chuunibaku history.

On July 1516, 7, the village chief of Windmill Village suddenly fell ill. After all, some things are destined. You arrived at the village chief's home with perfect accuracy and easily cured his illness, leaving the villagers of Windmill Village astonished.

On July 1516, 7, with the help of the villagers, you temporarily settled down in Windmill Village and opened a small clinic. After all, you needed to make a living. At the same time, you began to train your physique, striving to regain your Armament Haki as soon as possible. As the saying goes, a man should be self-reliant!

On July 1516, 7, in your spare time, you began researching ways to make money. According to the price list at a nearby shipyard, an old ship would cost about 10 million berries. Remember, the warship you sailed on in your previous life was nearly 20 times the size of this old ship, costing only 22 billion berries. Its firepower and sturdiness were completely different. Do pirates even have mines? Furthermore, you discovered that the most profitable industries in this world are all written in the criminal code, and then there's shipbuilding. Isn't this a vicious cycle? Why would I need money when I can afford to build ships? Finally, after some thought, you decided to try submitting an article to Rogue Town Magazine. Being a plagiarist in another world isn't shameful. As for subject matter, love is an eternal theme for humanity, even in the world of One Piece.

July 1516, 7. Finally, good news arrived. Today, your companion grandfather has awakened early. Yes, it's Roger, the amnesiac prisoner on death row. Through your interactions in these two worlds, you two have become close friends, like old friends.

July 1516, 7. Today, you ran into Luffy and Ace again. Luffy tried to be unsportsmanlike, but he had no hidden weapons, so after you caught him, you tore both of his cheeks into pieces. He was furious, but then you treated them to a meal, and you became instant friends. It was magical. During the meal, Roger told you that he felt an indescribable kinship with Ace. This is the bond between father and son!

July 1516, 7. Today, you received a manuscript acceptance letter from Rogue Town Magazine. Your short story "The Necklace" will be published in the next issue of the magazine. The fee is 15 million berries. This means you need to copy 120 short stories to buy an old ship. But it doesn't matter. I'm stubborn. Besides, this is a way to leave my mark in the other world. Money is secondary. Being someone who can personally change the world is also great.

From July to September 1516, you copied over ten famous romance short stories, becoming the most famous short story writer in the East Sea. According to your understanding, Rogue Town Magazine is owned by Morgans, the sole newspaper tycoon in the One Piece world, so they should have plenty of money. As expected, your royalties skyrocketed. Furthermore, your relationship with Ace and Luffy blossomed rapidly. You taught them the techniques for cultivating Armament Haki and Observation Haki. However, in the dozen or so battles that followed, Ace failed to defeat you once. According to your assessment, Ace's current strength is somewhere between a lieutenant colonel and a colonel at Marine Headquarters, and his physical skills aren't even as good as yours. Perhaps he'll truly take off after consuming a devil fruit.

On September 1516, 9, your savings reached 20 million berries, completing a quarter of your goal. That same day, you successfully cultivated Armament Haki. Two months ahead of your previous life, Roger told you that your current strength was not bad. He vaguely remembered that when he first set sail, he might not have been as strong as you, but if he wanted to make further progress, he still had to take to the sea as soon as possible. You agreed. Meanwhile, after this time together, you formed a deep friendship with the two brothers. Ace and Luffy both considered you a friend and a brother, and they were very close.

December 1516, 12. Today was both good and bad. The good news was that you had already completed two-thirds of your goals, and your fame as a renowned writer had spread throughout the Grand Line. Even princesses from several countries were fans. The owner of Rogue Town's magazine personally visited you, requesting that your work be reprinted in the World News, offering a generous fee. You had no reason to refuse. The bad news was that on this day, the mean old man Garp returned to Windmill Village. Compared to your previous life, he was even more interested in you, especially after you defeated Ace in a sparring match. He kept trying to trick you into joining the navy, but this time you held your ground. No one, not even an offer, could sway your resolve.

On December 1516, 12, after repeated attempts at persuasion failed, Garp, though regretful, gave up and turned to training Ace and Luffy. According to him, both of his grandsons were destined for future admiral status and would never lose to you. You curled your lips. Optimism is a good thing! It applies to both sides.

On January 1517, 1, under the guidance of Ai Tiequan, Ace also cultivated Armament Haki. At Garp's instigation, Ace challenged you again, but was again badly defeated. Then, Garp personally treated you to a good meal, and even Roger gloated over your misfortune. These two old bastards are truly worthless.

February 1517, 2. Garp had returned to Marine Headquarters a few days earlier on a warship. You finally achieved a small goal today, spending 6 million berries to purchase a beautiful ship and prepare to set sail. That same day, Ace approached you, telling you that he wanted him to come sailing with you, saying he could serve as a navigator, cook, and even help in combat. When you inquired about the reason, Ace told you a story about his father, Roger, and mother, Luju. He wanted to see for himself what magic the ocean held that could have so captivated his father, leaving his mother behind and never returning. Of course, it would be even better if he could create a legend surpassing Roger's with his own hands. After hearing this, Roger fell silent and repeatedly asked you to take good care of Ace.

On February 1517, 2, you spent two weeks crafting some simple medical tools, including a microscope and a simple blood analyzer. This wasn't a difficult task for someone with Iron Man research talent. You earned the achievement: Leeuwenhoek.

On February 1517, 2, after making all the necessary preparations, you named yourself the Pineapple Pirates, painted a skull with a pineapple hairstyle on your flag, and officially set sail. After saying goodbye to Luffy, you promised to meet again at sea.

On February 1517, 2, your first target was Rogue Town, then you passed the Upside-Down Mountain and entered the Grand Line. It's said that Stand users are attracted to each other, but it seems the same is true for Devil Fruits and people. By chance, you obtained a Devil Fruit on a deserted island. You gave it to Ace. In exchange, you received some blood samples from Ace before and after consuming the Devil Fruit. Under a microscope, you discovered some black granular material in the latter sample. Perhaps this is the legendary Devil Factor?
