Staying in the Magic City, I Rely on Devouring Machinery to Ascend

Gu Xingying traveled to the hierarchical magic city and became an E-class low-level casual cultivator who couldn't even cast fireballs. Late one night, he accidentally broke into the bloody scene where the underground giant was cleaning up the door. He thought he was going to be killed, but it turned out that the red-haired gangster Yan Huang, who was rumored to be murderous without blinking an eye, actually took him back to the penthouse as a stray dog! From then on, Gu Xingying was forced to start a "nightmare" living together with four top dangerous men: The violent killer Li Yi draws his sword every day to kill him; the sinister smiling tiger Shen Jingfeng uses her as a bait to test her wildly; and there is a top assassin Lin Xuan with severe social fears who clings to her as his only safe zone. Everyone thought she was a loser who could only survive on charity from big bosses. Until one day, the planet-level nano-intelligent brain "Tianshu" sleeping in her body completely awakened. Gu Xingying discovered to her horror: There is no magic in this world! The so-called magic power is all atmospheric nanoparticles left over from ancient high-dimensional civilizations! And she has the [highest administrator authority] on this planet! When the hypocritical "god" casts a curse to destroy the world, four big men covered in blood protected her behind her, preparing to fight to the death. Gu Xingying sighed helplessly, stepped forward and snapped her fingers. The forbidden curse in the sky collapsed instantly! Countless "magic elements" reorganized crazily, turning into a hundred-foot-tall plasma mecha that rose from the ground and shattered the god's halo with one shot! The big guys' views were completely shattered: "You call this an E-level casual cultivator?!" Gu Xingying's face was expressionless: "I'm sorry, the flesh and blood are weak and the machine is soaring. This planet is now under my control."
