Kill Me More Times, I'll Become Invincible - Chapter 36:

My name is Chen Huai’an, and I have cancer. I’m dying. Lately, I’ve become obsessed with a virtual girlfriend game. I top up my account to buy her cultivation techniques and magical artifacts. Even though I’ve emptied my wallet, I laugh like a fool. I always thought it was just a game—until one day, my virtual girlfriend sent me a pill. The next moment, the pill appeared in my hand… Am I… not going to die?!My name is Li Qingran. My cultivation has been crippled, my spiritual roots dug out, and I’ve been expelled from my sect. I cower in a dilapidated hut, waiting to die. I thought my life was over—until I met a mysterious senior who never shows himself. This senior heals my wounds and helps me cultivate. I grow stronger and stronger, eventually becoming the most powerful sword cultivator in the Cangyun Realm. I’ve heard that the spiritual energy in Cangyun is depleting, the Dao is dim, and an immortal from another world plans to merge their soon-to-revive realm with ours. An age of chaos and opportunity is upon us. Even immortals may face death in this struggle. I scour the world for traces of this senior. I want to protect him—and become his Dao companion!!!

“I wasn’t born a lucky person, I’m just too strong.”

This is my first original novel, it may be bad, but this is all in my mind and imagination. (Warning!! There will be an Incest genre) Thank you o⁠(⁠(⁠*⁠^⁠▽⁠^⁠*⁠)⁠)⁠o(oh yeah I forgot, this cover is not mine, I just edited it, if you feel you own it and don't like me using it, please tell me)

Gu Jin crossed into a novel as the supporting character and best friend of the main female lead, Cheng Xin.

Cheng Xin was frequently surrounded by men of status and quality. As Gu Jin was the female lead’s dearest friend, she doesn’t mind settling for the leftover meager soup if the female lead chose to eat the meat. The two sisters believed they’d enjoy this friendship for a lifetime.

But just as she was ready to latch firmly unto Cheng Xin’s golden thigh, she discovered the body she crossed into had memories of future events beyond the novel’s plot, finding out that her marriage would end in utter failure.

The female lead, Cheng Xin who often quarrelled with the male protagonist would head over to Shao Chong for comfort even though Shao Chong was married to Gu Jin. And after several incidences, Gu Jin advised Shao Chong to have a sense of propriety as her spouse but he told her not to think too much about it, claiming that he only maintained a pure friendship with Cheng Xin.

On the day Gu Jin was kidnapped, her good husband stayed by her cousin’s side and accompanied her to the hospital.

When Gu Jin transmigrated into this new world and learned of the truth, she did not wish to waste this new life as a supporting role for her cousin as the previous soul had done. She’d not live a life as a spectator in someone else’s love story. No. She would be the protagonist of her own romance in this new life.
