[Dual World Travel + System + Multiple Heroines + Cultivation + Spiritual Qi Revival]
Spiritual qi revival sweeps across Blue Star. Chaos is coming, and martial arts are quietly on the rise.
Lu Xiu is a poor student who was swindled out of all his hard-earned money by a crooked martial arts school. By chance, he activates the Two Worlds Travel System.
It actually lets him travel to a world of cultivation.
A lowly servant, bullied by everyone? He brings Blue Star Desert Eagles and sniper rifles to the cultivation world, treating his enemies to free bullets.
No good teacher to guide him? Martial arts techniques developed with modern technology are top-tier body-tempering arts in the cultivation world.
Poor aptitude? High-tech marrow-cleansing liquid works as well as the finest marrow-cleansing pills in the cultivation world, yet on Blue Star it can be bought wholesale.
Short on resources? He trades pills, magical artifacts, and spirit herbs between the two worlds, getting rich overnight.
Starting as a demoted servant, Lu Xiu gradually embarks on a path to rise to power, traveling between two worlds, trading resources, cultivating both immortality and martial arts, and making a fortune.
Crooked martial arts school: Please, Hero Lu, have mercy! We're about to go bankrupt.
Ungrateful junior sister: Senior Brother, give me spirit stones and cultivation techniques, and I'll agree to dual cultivate with you.
Sycophantic master: For old times' sake, could you lend me a bottle of marrow-cleansing liquid? I'm just a tiny step away from a breakthrough.
Lu Xiu sneers: You think you deserve it? I'd sooner feed my things to a dog than give them to you. Get lost!
P.S. This story involves the protagonist's whole body traveling, not just his soul. The System tag is inaccurate.
