Players are coming, fortunately I have a time travel simulator

From March 2013 to January 3, you began your studies at the Shinō Academy. During that year, your reputation as a genius spread like wildfire. In a remarkably short period of time, you reached level six in spiritual power, mastered most of the ghost arts within the Shinō Academy, and were also very accomplished in white-handed fighting and slashing techniques. You passed five exams in a row and were only a hair's breadth away from graduation.

It's not that you're deliberately trying to show off, but rather that you have a trump card. The process of crafting the Collapsing Jade actually contains a method for increasing spiritual pressure. With your scientific research capabilities, it's not difficult to extrapolate this knowledge. Once awakened, the Collapsing Jade can possess spiritual pressure far exceeding that of a captain-level warrior. By combining spiritual particles with certain catalysts to create a potion, you can significantly increase your spiritual power. (You have obtained the item recipe: Spiritual Power Potion.)

Furthermore, you were already fully acquainted with the skills of the Death God world in your previous life, having mastered them to a profound degree. This life will only make you even stronger. Furthermore, through the long-term use of spiritual potions and the continuous development of the abilities in your memories, you can feel your physical fitness and spiritual power constantly improving, and you're far from reaching your limit.

Coincidentally, the teacher teaching you about Zanpakutō was wearing a white haori and black-framed glasses. He was none other than Aizen Sosuke, the man you greatly feared. While teaching you about Zanpakutō, he used the opportunity to introduce Shikai and Bankai to perform a Shikai of Kyoka Suigetsu, hypnotizing everyone. This made it easier to control them later.

[Luckily, you know how to break Mirror Flower Water Moon. The hypnosis effect can only be triggered if the opponent witnesses or has witnessed the moment of its release. Also, touching the blade before Mirror Flower Water Moon's full hypnosis ability takes effect will break the hypnosis effect.]

[Aside from this little incident, your shallow strike has also undergone a dramatic change. The blade has become increasingly narrow, as if it were to merge with the blade's back, appearing sharp and slender. You can even see drops of petal-shaped blood on the blade, with a slight smell of blood.]

Perhaps this bloody smell comes from your experiences in the reincarnation world. After a long period of tempering in blood and fire, you are no longer a kind person at heart. As a qualified reincarnation, you are undoubtedly a chaotic and evil being, willing to do anything out of greed, hatred, or desire.

【Based on your previous experience, as long as you know its true name, you can complete the Shikai smoothly. Just let it go.】

During this time, you also quietly began crafting the Collapsed Jade. During the fourth and fifth exams, you had the opportunity to travel to the human world once and three times, respectively. You used these opportunities to collect both Whole Souls and Hollow Souls. The Whole Souls you collected were mostly the souls of the most vicious Fullbringers, who are most vulnerable to Hollow Souls because they all contain fragments of the Soul King. This way, you could craft the Collapsed Jade with minimal effort, achieving three goals at once.

In March 2014, the opportunity you had been waiting for finally arrived. During a battle with a Hollow, you naturally and naturally resonated with your Zanpakutō.

[At the same time, a liberating message appears in your mind: "Where is the God, where is Taiyi? Shine! Rainbow!"]

While the release words may sound a bit childish, their power is incredibly powerful. Almost instantly, the shallow sword in your hand is transformed into a golden blade dripping with petal-like blood. The blade is spiraling, and a rainbow-like light entwines around its tip, capable of extending and devastating the opponent. You have obtained the First Release: Rainbow.

After you chanted the words of the first enlightenment, the blade of your Zanpakutō extended like a rainbow. In a flash, it pierced through the Hollow in front of you and flattened a mountain in front of you.

"Very interesting!" You couldn't help but laugh. This Zanpakutō is every bit as powerful as the bonesaw from your past life. In some ways, it's even stronger."

On April 2014, 4, you finally completed the graduation exams from the Shinō Spiritual Academy, placing second overall and being directly assigned to the 17th Division, where you were assigned the third seat. Your captain was Ukitake Jushiro, and your nominal clan member, Shiba Kaien, was your vice-captain. It's worth noting that Rukia Kuchiki, the heroine of Bleach, was also a member of the th Division.

[Joining the 13th Division was something you had planned long ago. The 13th Division's main responsibility is purification, responsible for purifying the Hollows that have escaped to the human world. This is also the best way for you to collect materials for the Collapsing Jade.]

If nothing unexpected happens, Rukia Kuchiki will soon travel to the living world to purify the Hollows. She might even encounter Ichigo Kurosaki, the protagonist, who can see her. As the story progresses, Rukia will encounter an accident during the battle with the Hollows, transferring her own Shinigami power to Ichigo Kurosaki. Then, someone from Soul Society will arrest Rukia on charges of secretly passing on Shinigami power and failing to return within a certain time limit. It's a bit melodramatic. All you have to do now is quietly build up your strength and wait for the story to unfold.

From April 2014 to September 4, in those three years or so, your strength improved tremendously. Upon arriving at Squad 2017, you battled Kuchiki Rukia, but the result was a draw. But three years later, while still maintaining your own strength, you surpassed Kuchiki Rukia in strength, even matching Vice Captain Shiba Kaien with a draw. This meant that your strength had essentially reached captain level.

[Also, you've almost gathered all the necessary materials, including the souls of hundreds of Fullbringers and thousands of Hollows. This is much easier than what Aizen achieved before, when he sacrificed tens of thousands of elite souls from Rukongai. This also means you can now secretly begin crafting the Hogyoku.]

The production process is more difficult than you might imagine. After all, in previous lives, two scientific geniuses, Urahara Kisuke and Aizen, only managed to create two half-finished Hogyoku. Even with your powerful scientific research abilities, it wouldn't be something you could accomplish overnight.

In November 2017, you created a semi-finished version of the Hougyoku. The basic material was the Hollow you captured, and the final form manifested as a gem shimmering with a bluish-black light. Its awakened spiritual pressure was so intense that it made you shudder. You can now use it to break the boundary between Shinigami and Hollow, turning Shinigami into Hollows, or Hollows into Shinigami. However, to complete it, you need to add more souls and Soul King fragments.

I must commend you on your wise decision. The soul of a Fullbringer is inherently stronger than an ordinary soul, and within it resides fragments of the Soul King. After four months of tireless experimentation, in March 4, after the fusion of all souls and Soul King fragments into the Collapsed Jade, the Collapsed Jade before you began to jump restlessly, and a large amount of grayish-white mist emanated from it. This was the filtered soul impurities.

[When the Collapse Jade finally quiets down, it means it has been basically created. Now it seems to need more "fuel". You have obtained the Miracle Item: Collapse Jade (Complete).]
