Binding slogan: "If you don't seek death, you won't die, but if you seek death, you can accumulate merit and become stronger." Core mechanism - Complete the "Death-seeking but Harmless" mission to obtain merit points. The merit points can be exchanged for martial arts skills (fighting, self-healing, weapon proficiency, etc.) And special props from the Marvel world (weakened version of infinite gem fragments, vibranium commodities, etc.); If excessive attempts at death cause large-scale casualties, the merit points will be deducted and even trigger a "lightning warning" penalty.
