How Come I, the King of Fighting, Have Become an Ultra Soldier?

[You traveled to the Ultra world and became an Ultra soldier who was beaten away by Belia with a stick] [In order to become stronger, you invite the strongest warrior in the Kingdom of Light, Ultraman Zero, to train yourself] [After a long period of training, your strength has improved, now try to defeat him] I can't remember how many years ago, the soul of a modern young man passed through Leo's human body Fengyuan. After going through a high-intensity monster-fighting dungeon on Earth and devil training from the crutch star, he finally became the uncrowned "King of Fighting" in the universe. And his system was tens of thousands of years late, and it only arrived today when he was training Cero in the name of the King of Fighters. "It doesn't matter if you are late, why is it still a malfunctioning version? Are you going to judge the Lion Warrior as an Ultra Soldier?" Facing the young boy Zero who was wearing training armor, Leo defeated him effortlessly. [Congratulations, you defeated the strongest warrior of the Kingdom of Light, Ultraman Zero, just as a fledgling] This book is also called: "I am the King of Fighters, so it is reasonable to speed through the Tiga dungeon" "You're already playing Chiton alone, why are you still clamoring to become stronger?" (The author traveled through time to become Ultraman two years ago and now lives in the Kingdom of Light. He did not take anything for granted and did not write randomly)
