Shared Transmigration: The Timeline Is Too Early

My name is Ron. I died. Then I transmigrated, and I even transmigrated together with my entire body. But isn't there something wrong with the timeline? Why is the timeline where I ended up so far in the past? In the Demon Slayer world, what do you mean Yoriichi Tsugikuni only died recently? What do you mean our family knows the Sun Breathing Technique? As everyone knows, the Sun Breathing Technique was essentially lost after Yoriichi's death. The main reason, of course, was Muzan's fear of Yoriichi Tsugikuni. In the Bleach world, I transmigrated to a time a thousand years before Bleach began. Yamamoto Genryusai Shigekuni had just formally established the first Gotei 13, and I was forcibly conscripted to charge into battle with a sword against Yhwach? In the One Piece world, the Rocks Pirates had just invaded God Valley, and unfortunately, I happened to be in God Valley~ In the Naruto world, the First Hokage and Madara had died, and unfortunately, I happened to be a Konoha genin. Even more unfortunately, the First Shinobi World War was about to break out.
