The Game Starts with Hiden Hiikage, but Why Is He Only Nine Years Old?

Li Haotian modified the time and rescued Li Youer, but the impact of modifying the time on the entire world is immeasurable. Part of the world's time and space was disrupted, and Xu Tingfei was accidentally backlashed by time and space by chance and traveled to another universe. Xu Tingfei came to another universe and saw light and shadow armor and supernatural beasts that had never appeared in his memory. However, he was not afraid of challenges. He believed that the flying shadow armor could solve everything. But the question is... Why is he only nine years old? Looking at his limp body, Xu Tingfei only felt weak. Fortunately, the strength of his mental energy did not change with the changes in his body. He was still the best summoner of Feiying Armor in the world. As Xu Tingfei took action again and again, Lufa also woke up early due to the Feiying Armor. Faced with the threat from Lufa, Xu Tingfei had to rebuild the armor team, but looking at the taciturn nine-year-old Xiaotian and the hot-tempered and impulsive eight-year-old Xiaogang in front of him, Xu Tingfei only felt a headache. (I know that Kai 1 and Kai 2 are a world view, but the settings of the two screenwriters conflict, and I don't know how to reconcile some parts, so you just think that Xu Tingfei is from a parallel universe. Except that there is no Kai 1, the rest of the plot is exactly the same as the original one. Then when you travel over, you can be the main universe, with Kai 1 and Kai 2 connected.)
