National Concrete: I Can See the Second Half

A thousand years ago, mankind discovered a mysterious substance. As long as it is used, mankind will have concrete superpowers. As long as you have read or watched entertainment works, you can visualize them and use them as superpowers. Dragon Ball, Naruto, One Piece... Some people practice fighting spirit, some specialize in ninjutsu, some have fruit abilities, and some are Pokémon trainers... The era of universal people and worlds is coming! Ye Feng, an earth otaku traveled through time, only to find that there was a gap in the new world! Is there only the remnant of Naruto? Does anyone know about the Mangekyo Sharingan? No one knows about tailed beasts? One Piece only has 100 paintings? Only a few of various fruits are produced? Does the Martial Arts Continent only have fragments of scrolls? Once you get to Dou Wang, there will be no more content? Dragon Ball only has urban chapters? Saiyans have no idea what the hell is going on? This novel and its characters are purely fictitious.
