[No romance + high martial arts + rapid advancement, no level bottlenecks] The cultivation levels go up fast. Seriously, guaranteed fast. Zhang Zheng has just transmigrated into the body of a no-good high school student with the same name when he gets bound to the strongest security guard System. While everyone else trains hard for the martial arts exam, he just strolls around and watches his vital energy soar. [Ding! First night patrol mission complete. Host receives 100 points of vital energy and night vision!] [Ding! Congratulations, Host, you’ve advanced a level. The System awards you another 500 points of vital energy!] Campus belle: Zhang Zheng, come to my dorm and take a look! There’s something weird in my closet! Zhang Zheng: On my way! Keeping the campus safe is my responsibility! v'ᴗ' ի [Ding! Defeated the Color-Hiding Beast. Host receives 500 points of vital energy, one random martial skill, and one Blazing Shield!] Principal: You’re the strongest fighter at our school. Come back and compete in the martial arts exam to bring glory to the school! Zhang Zheng: No thanks. I’m a security guard, and I love my job.
