MTL - Valkyrie of the Marvel Universe - ~ Please help me to think of a battle pattern

I reincarnated with e*otic game skills, but this is apparently an apocalyptic dark fantasy. I can’t die, so I tried to save the world with e*otic game skills… “Saint! Save us!!” “Saint! Save us!!!” People keep calling me a saint.

In the novel, there are always characters who are strong, powerful, and on top of that have stunning appearances, but because of the plot arrangement and influence of the protagonist's halo, their endings are embarrassing and miserable.Jiang Jiamian’s mission is to save them.Jiang Jiamian: “It's actually very simple, just seduce and hook them up so that they no longer have time to follow the plot.”If the mission targets don't follow the plot, they can break free from the storyline and even avoid contact with the protagonist.But why do all those miserable bigshots seem to have gone crazy and turned dark all of a sudden?

Learning crude martial arts had always made Fourth Miss Zhu the laughingstock of Beijing’s elite families. In their eyes, such skills were fit only for common bodyguards.Yet Zhu Changle, who considered herself invincible, felt no shame. On the contrary, she took pride in her abilities.Not everyone could protect their own household, but she could! And exceptionally well at that! She’d even dare to turn the whole of Beijing upside down for the sake of her family’s estate!Don’t believe it? Just try her!

[You have been killed by the Hero of Light.]

[You have died.]

I had died at the hands of the main character in the novel I had read before.

But I got another chance. I regressed and returned to the time when I first entered this novel world.

Once again, I live in this novel world as an extra character.

Since I have experience and knowledge, especially my World System which had upgraded, I'll do what I want to do.

I will become stronger than the main character.
