Shuanglong Mixed with Rivers and Lakes

[New sci-fi martial arts theme + dual protagonists + Star Wars elements added in the mid-term + cute new author] The two scourges of Double Dragon City, Jia Zhengjing and Hua Wuxie, were tricked by an old beggar into buying a copy of "Invincible Book". "After practicing this skill, you will be invincible in the world!" The old beggar promised, patting his chest. The two believed it and left home to travel around the world. In their first fight, Jia Zhengjing used abacus beads to break off the front teeth of the leader of Heifeng Village, while Hua Wuxie lost the opponent's eyes by sprinkling lime powder. Rumor in the world: "Two shameless scum have emerged from Shuanglong City!" Jia Zhengzheng waved his folding fan and smiled: "The humble are invincible, you understand?" Hua Wuxie wiped the rusty iron sword: "Sword? No, this is called a mean way." The pawnshop owner stared at the family heirloom swords they pawned: "These two pieces of scrap metal... Are you sure?" Little did they know, the ruined sword contained a shocking secret that would stir up the world.
