第1章 儿子的礼物：一张特殊的起爆符！

A gift from my son: a special detonating talisman!

[Explosive Talisman Brain Hole] + [System] + [Not Invincible] + [Early Stage Survival] + [Prioritize Learning Life-Saving Skills]

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.

Yuan Fei Hiruzen: Huh? How come your shadow clone is several times stronger than your original body?

Itachi Uchiha: Huh? Why is the flame black when this detonating tag explodes? Holy shit, this... is Amaterasu?!

Asuma: Boss, I'm really fascinated by this cigarette made with the detonating talisman. Do you have any more? Please give me another one...

Tsunade: Why is this boy's palm magic so strange? He... he is using his feet to perform palm magic?! Nima! Take your feet away!

Namikaze Minato: Ebisu-kun, how come your Flying Thunder God Formation is faster than my authentic Flying Thunder God Formation? Excuse me, could you... teach me?? Sorry!
