I recommend the two novels "The Boundless Martial Arts" and "The Heavenly Crystal Reincarnation of Martial Arts". These two novels were both sci-fi and time-travel novels. The protagonist could travel through the martial arts world and bring people back to the main world. The main characters in "The Heavenly Crystal Reincarnation of Martial Arts" could even travel to different Wuxia realms, including classic works such as "Condor Shooting,""The Smiling Proud Wanderer," and "The Heaven Sword and Dragon Sabre." I hope you like this fairy's recommendation. Muah ~π
