Naruto: This Ninja Is a Bit Too Real

Traveling through the ninja world, blood successors, tailed beasts, and senjutsu, these plug-ins that are readily available to travelers seem to have nothing to do with Ye Yuan. It was only when he cut the enemy's throat with a cold kunai for the first time that he discovered that this was a real world. The fire escape is not that it cannot burn people, but it can easily turn the body into charcoal. The kunai shuriken is not always accurate. With the use of ninja war tools, it can easily take away people's lives. Tsunade, Terumi Mei, these beauties of the ninja world have never been seen by Yahara after living in the ninja world for more than ten years. Opportunities and resources can only be obtained one by one with his own hands. Rather than dancing with Madara, he just wants to survive tomorrow. This is a real ninja world. (Slow-burning works, the protagonist is neither weak nor abusive.)
