In the world of Naruto, Lin Yu accidentally traveled through time and came with a forbidden jutsu reproduction system, which could increase the power of the ninjutsu he saw to the forbidden jutsu level. When he first traveled through time, he was involved in a ninja battle and used the power of the system to save a person, which also attracted the Akatsuki organization. After a fierce battle, Lin Yu decided to go to Konoha Village, helping others along the way, harvesting ninja clothing and tools, and finally arrived successfully.
When arriving in Konoha Village, Lin Yu experienced a series of events. He first helped the villagers catch thieves, then fought against a mysterious woman, and joined forces with members of the Akatsuki organization to fight against the mysterious organization, gradually uncovering a huge conspiracy involving the entire ninja world. It turns out that the mysterious organization is looking for ancient power in an attempt to subvert the world, and this power is related to ancient ruins.
Lin Yu and Xiao organization members followed clues and came to the ruins. There was a powerful seal in the ruins. After they broke the seal, they were pursued by a mysterious organization. In the ruins, Lin Yu gained mysterious power, defeated members of the mysterious organization, and learned that there was a more powerful force behind the scenes.
After that, Lin Yu returned to Konoha Village, and after discussing with Tsunade, he and Kakashi went to Sunagakure Village, Kirigakure Village, and Kumogakure Village to persuade them to join the alliance against the mysterious forces. In the process, they encountered various challenges and obstacles, including attacks by mysterious organizations and doubts in various villages, but eventually succeeded in achieving their goals.
