How a Cat Won Over the Cool Senior Sister

The cool, ruthless, mighty demon slayer who secretly adores fluffy things, gentle senior sister x the arrogant, tsundere little cat who is actually a coward with weak spiritual power

Also known as: The Cat Gets Bound to a Kill-Your-Wife-to-Prove-Your-Dao System

The quickest path to ascension for a cultivator practicing the Heartless Dao is to kill their wife to prove their Dao.

As it happens, Qian Chan gets bound to a baffling Kill-Your-Wife-to-Prove-Your-Dao System.

The System says: You need to make Shen Lingfu, the mighty demon slayer of a major cultivation sect, fall in love with you and marry you. Then have her kill you and switch to the Heartless Dao. That way, you can bring your clan back to life.

Qian Chan is a cat demon. Her clan was wiped out by cultivators like Shen Lingfu, and before the cat elder died, she told Qian Chan that she had to survive.

Qian Chan and Shen Lingfu are sworn enemies.

But to bring her clan back to life, she has to do what this thing called the System says.

Step one: The cat needs to get close to Shen Lingfu.

Step two: The cat needs to keep her identity hidden.

Step three: The cat needs to do everything she can to cuddle up to Shen Lingfu.

Step four...

The cat has no idea how to make Shen Lingfu fall for her, so she follows each of the System's detailed steps.

But one day, her identity is exposed. She rushes down the mountain and runs straight into Shen Lingfu, covered in blood after cutting off a snake's head.

The cat has little spiritual power. No matter how loudly she calls for help, nobody answers, and even the System, which has demonstrated how to woo Shen Lingfu eight hundred times a day, goes silent. In her panic, the cat flattens her ears and faints.

When she wakes, the legendary cool senior sister is holding her in her arms, gently rubbing her fluffy cat ears as she smiles. "Little kitty, why did you faint?"

Shen Lingfu, who seems like a demon-slaying expert, appears to be the cat's only protection.

So Qian Chan resolves to practice her cultivation diligently by day, then turn back into a cat at night and stay by Shen Lingfu's side, never going anywhere.

As they spend more time together, Shen Lingfu opens her heart to Qian Chan.

They sit side by side and watch the moon together.

Sometimes Shen Lingfu feels lonely and leans against her. "Actually, I don't have any friends in the sect. It feels like you're the only one who stays with me."

Sometimes Shen Lingfu is happy and tugs on her whiskers. "I let a whole nest of squirrel spirits go today, and they gave me a huge pile of pinecones."

Sometimes Shen Lingfu is confused and strokes her head. "Master says I have a gift for the Heartless Dao, but I don't want to practice it..."

Every night, Qian Chan listens to Shen Lingfu chatter until she gets sleepy, then curls up in Shen Lingfu's arms and falls asleep.

Until one night, Shen Lingfu strokes her head and softly asks, "Qian Chan, can you stay with me forever?"

Qian Chan realizes Shen Lingfu isn't as cold and heartless as people say. When the System reminds her what to do, she transforms into human form first, affectionately licks Shen Lingfu's face, and wiggles her cat ears. "Will you marry me? Then we'll always be together."

Later, Shen Lingfu really does marry her. She kisses Qian Chan, hugs her, lifts her up high, and even grills fish for her.

Qian Chan seems to have changed her mind about letting Shen Lingfu kill her...

-

Shen Lingfu was once a leading talent among the immortal sects and a favorite to ascend. After marrying Qian Chan, she was expelled from her sect.

Her master once came to tell her in secret that changing to the Heartless Dao was the true path to seeking immortality.

But Shen Lingfu has killed so many demons, and in the end, it was a cat who warmed her frozen heart. To prepare lots and lots of dried fish for the cat, Shen Lingfu goes fishing in the river every day.

The cat is called Qian Chan.

Qian Chan is always by her side.

Qian Chan says she likes her.

Qian Chan cares about her.

But one day the cat says they are enemies and tells her to kill her with her own hands...

Happy ending.

Both leads are each other's first and only.
