I Summon Players in the Ninja World

Travelers who don't dare to change history are trash. Travelers who have a system but don't dare to change history are even worse than trash. Chi Xiao, a young man from Earth, traveled through time and became a famous name in the Country of Waves. He holds a game system that can summon players. Now that he has a system, Chixiao will definitely make a big splash in the ninja world. Since then, the structure of the ninja world has completely changed. Because of the existence of players, making balls is popular in the entire ninja world. The origin of the First Ninja World War also became players discussing how to eat meatballs, which evolved into a dispute between the sweet party and the salty party. The last research topic in Senju Tobirama's life was "An examination of the evidence that Uchiha's evil aura is contagious" The entire ninja world has completely changed its appearance. And this is just the beginning.
