In some year in some comic universe, a high school student from another dimension accidentally brought a wuxia and occult "X" System with him when he transmigrated to the disaster-ridden Marvel Universe...
From then on, the Marvel Universe also saw the emergence of powerful techniques such as "Eighteen Dragon-Subduing Palms," "Thousand-Mile Instant Travel," and "Nine Yin White Bone Claw," as well as "Mechanical Puppets," "Corpse-Driving Arts," and "Soul-Summoning Techniques"...
P.S. Not everything in the protagonist's System shop can be purchased.

Movie or comic? If it's a movie, it's understandable if the system reward technique is a residual scroll, but if it's a comic, it's just seeking death.
