Ninja World: the Strongest Jutsu Style

Long Yu traveled to Hokage and inherited a second-hand ninja shop. As a time traveler, he has not yet activated the system. He can only rely on his grandmother and live an ordinary life. Until the age of 5, the little-known Long Yu showed super talents of five chakra attributes in the Renmin school entrance test. Together with Kakashi, he became the strongest dark horse at that time, which directly detonated the public opinion field in the streets of Konoha. At the same time, the system called Spell Refining was also successfully activated. Long Yu knew that his time had come. This novel and its characters are purely fictitious.
