Naruto: Torrent of Steel Overwhelms Five Shadow Alliance

Li Zhishui found that he had traveled through time and became Pain Shura in the world of Naruto. Yes, that's the mechanical bioman with a shaved head and weapons all over his body. But that guy was a finished product of the third generation, and the body he traveled through was a defective product of the first generation. What's even more surprising is that the body used for transformation turned out to be the famous Uchiha Shisui of Konoha Ninja Village. Ah, the time for revenge has finally come! When Shisui turned around, he realized that the Uchiha clan had been wiped out, Pain had been silenced, Danzo had burped, the Fourth War was over, and even the protagonist of the story, Uzumaki Naruto, had already saved the world! Then didn't I just rush to a late show and feel lonely? Bite! The scientific and technological civilization system has been activated! Shisui suddenly realized that there seemed to be quite a lot he could do! Shuriken and blasting charms? Do you want to try my new MP7 submachine gun and M84 infantry grenade? A powerful fireball technique? It's okay, I have a flamethrower here. A farmer can use it skillfully after a day of training. It won't hurt his lungs and won't burn his mouth! Shinra Tianzheng? Look at the b52 flying overhead, the Figure 160 and the H-6X pro. Do you need to add cumin to your barbecue? The strongest ninjutsu in the ninja world, the Susano Kyuubi combined with Naruto? Sorry, I really don't have Gundam here, but please don't forget the fat man and the little boy who once bloomed in this land... Wait? Is my Star Destroyer built? Some years later: "Mr. Shisui, do you have any suggestions about the totems of our Rainbow Kingdom?" "That rabbit with only the Sharingan is pretty cool!"
