Legend of the Nine Tails

A person who had seen some Naruto anime but not manga had transmigrated. He transmigrated into the stomach of Uzumaki Kena, and his name was " Uzumaki Naruto." Then, he became the nine-tailed human pillar. Next, he experienced the same childhood as Naruto in the original novel. What would the result be? Would Naruto’s world change after the main character appeared? How strong were the nine tailed beasts? Or was it really as easy to defeat as in the anime?
