After traveling through Naruto, the system competed with Naruto Tiandao for the right to rules and was forced to explode, leaving only the core of the system to manifest all things and be inherited by the traveling Uchiha source.
Become Uchiha's exclusive escape technique, Mouth Release. As long as there is enough chakra, you can manifest all things, and the sealed book will come out when you open your mouth.
There are also various items and technological drawings from other worlds waiting to come.
Respect the original system + be reasonable.
