Chu Haoran, who traveled through time and space to become Ebisu in the Naruto world, unfortunately happened to catch up with the Second World War in the Ninja World.

Fortunately, as a time traveler, his golden finger is still there. If he reaches the maximum proficiency, he can mutate the ninjutsu and be rewarded with the opportunity to copy the ninjutsu next time.

He also unlocked the bloodline limit of barrier affinity. Why would he learn Flying Thunder God? With barrier affinity, wouldn't it be better for him to learn Flying Thunder God Formation? Since then, the name of Black Flash has been resounding throughout the ninja world!

Enter the R&D department, improve the detonating tags, customize the production line, and equip every ninja on the battlefield with a stack of them! The enemy will be in utter disarray.

Enter the medical system, create the "Big Band-Aid" of healing, and liberate the medical ninja!

Apprentice to the barrier class, use barrier affinity to build a barrier version of Gundam Susanoo!

Orochimaru, the master of mouth-to-mouth, perfectly inherits Hashirama's cells and helps him embark on the path of becoming a true great scientist.
