Become a Cannon Fodder and the Female Supporting Role Gains Immortality

Su Susu didn't expect that she could wear a book and turn into a vixen. Moreover, she is a cannon-fodder demon who has a crush on the male protagonist and risks her life for him, but is not even named in the original work. What's even more tragic is that she also has to attack the culprit who killed the original owner - the second male who hates monsters extremely, has a sworn hatred with monsters, and vows to destroy all monsters in the world... Being pushed out of the market, Su Susu had no choice but to bite the bullet. I thought I could successfully complete the task if I was careful, But what I didn't expect was to start over again and again. First time, Facing the shimmering sharp blade in front of her, Su Susu suppressed her fear and secretly glanced at Xiao Yan affectionately, hoping that the other party would be fascinated by her beauty and let her go. But unexpectedly, he was stabbed through by the demon-slaying knife. The second time, Meeting Xiao Yan, the "god of murder" again, Su Susu knelt down with a very hopeless sound, hugged his thigh and cried loudly—— "Hero, spare your life!" "I have an eighty-year-old mother and a three-year-old child, so why don't you treat me like a fart?" "Killing me will dirty your hands!" Of course, he couldn't survive more than three seconds this time. The third time, she turned around and ran away without thinking. If you can't afford to offend, we can afford to hide. But I didn't expect—— System: "Departure from the mission target will be treated as a failure." Susu: "..." After reversing three times, she became angry. I don't want to play anymore! Love as much as you like! Then the fourth time... Xiao Yan: "Hand over the things." Su Su: "Can I survive if I hand it over?" Xiao Yan wiped his polished knife, glanced sideways at her, and said in a serious tone, half-smiling but not smiling, "How is that possible?" Upon hearing this, Su Su immediately took out the fairy grass stolen from Xiao Yan's master's sect and stuffed it into her mouth with an expressionless expression. "Crunch, crunch..." "It tastes really bad." Faced with this saucy operation, even Xiao Yan, who had seen many storms and waves, couldn't help but be stunned. Do all monsters nowadays seek death like this? So he was stabbed again. However, this time, Susu not only did not die, but also became an NB existence that could not be killed no matter what... Xiao Yan:! ! ! ? ? ? Susu: Hehehe (squints and smiles) Purpose: Be more Buddhist and face life
