Doraemon Starry Sky

When I woke up, I became Nobi Nobita's biological brother! I thought that with Doraemon's universal pocket, I would be able to embark on an adventure like a chance to win, but an unexpected time machine trip made me meet Kudo Shinichi, the "savior of the Japanese police" in the Heisei era. Only then did I suddenly realize that I had entered a wonderfully intertwined parallel world - the early stage revolved around Doraemon's daily fantasy, and occasionally there would be surprise guest appearances by characters from Detective Conan, but they would not focus too much on complex cases, and would slowly merge with the suspenseful reasoning there in the later stages. I am 3 years older than Kudo Shinzo, but after all, I am just a ten-year-old child now. Although I carry the memories of my past life, they are limited - I passed away when I was 12 years old in my previous life, so I can't remember much. So you don't need to think of me as an adult, I'm just an ordinary child, just with an extra layer of identity as a time traveler. (Author's words: The core setting of the protagonist is a ten-year-old child, with scattered and limited memories of his past life, and he will not act from an adult perspective. In the early stage, the relaxed fantasy of Doraemon's world is mainly used, with Conan elements as embellishments, and in the later stage, the suspense line is naturally integrated, striving to balance the styles of the two worlds and avoid being abrupt.)
