High Martial Arts: From Mechanic to Sword Immortal

Han Feng transmigrated to a world of high martial arts and was bound to a system called "Sword Immortal Growth Assistant"! However, the system had a bug, mistaking an airplane for a flying sword. So, Han Feng enrolled in a flight academy, piloted fighter jets, and practiced sword control techniques. [Host detected flying on a sword, Sword Control Technique Proficiency +1!] Launching a smoke grenade, System: [Congratulations on comprehending the sword technique "Splitting Light and Shadow"!] Dropping a thermobaric bomb, System: [Congratulations on comprehending the wide-range sword technique "Wildfire"!] Firing an aircraft cannon, System: [Congratulations on comprehending "External Sword Qi Release"!] Pressing the missile launch button, it's: "Sword Qi Stretching 30,000 Miles!" From then on, he embarked on an absurd path of sword cultivation! Decades later, when the Demon God exhausted all its strength to destroy Han Feng's vehicle, it saw a sword immortal surrounded by sword light. Demon God: "Immortal Master, is it too late for me to stop now?"
