(Shuangwen + Black Belly + Gaowu) Alien invasion, the human race has entered the era of national martial arts! In terms of potential, his martial arts qualifications are mediocre. In terms of background, he is poor and has a younger sister. In terms of strength, his combat ability is at the bottom.
