The school beauty asked me to mod a mech model — I built her the real deal instead

Yun Shiman, the school beauty of Biancheng Institute of Technology, built a 23-meter-tall walking mecha model for the Future Concept Tech Expo. To make it eye-catching, she asked her senior, Li Tianhang, to modify it to look more "high-end." Taking the job, Li Tianhang silently activated his newly bound [Super Modification System]. In just one week, he turned this model into a real, fully functional super mecha! At the expo, facing everyone's doubts, Yun Shiman put on a brave face to demonstrate the "fake" joystick-controlled walking tech. The next second, she piloted the 23-meter steel behemoth on a city rampage, even completing an earth-defying mid-air transformation! The venue fell dead silent, and the school beauty was completely stunned: "Senior brother, I just asked you for a modification kit, and you built me a super mecha?!" Li Tianhang shrugged helplessly: "Junior sister, you were the one who asked for something eye-catching and high-end. How is this my fault?"
