What’s not to love about my new life after transmigrating into a Pet-centered world?
There are mighty creatures that come in all shapes and sizes. They can either be cuddly companions, helpers in your daily life, daring scouts or strong fighters. Or all of the above. Not bad, huh?

I have a family, but the fact is completely overshadowed by my younger sister. She thoroughly hates my guts, and she makes sure that I know this. Every. Single. Day.
Did I mention that she’s disgustingly talented while I am a bottom feeder? A terribly handsome one at that.

I have free rein to run the family business on my own. A small and quaint Pet Store. It should have been great if not for the fact that the previous owner of this body was born with ZERO affinity to handle Astral Pets…

It wouldn’t be a proper transmigration without a gimmick or a system to pave my road to greatness, don’t you think? I have one, but I don’t know if I would be better off without it…

In that life, Fan Qingyao was the daughter of a famous family, the successor of a miraculous doctor, and her medical skills were superb. But she poisoned the traitor Zhongliang, considered the thief his father, and threatened her relatives to seek power and seize the throne for him.

The whole family of my grandfather died without any body parts, and my brother was burned into a handful of ashes. Having been drained of all her value, she was thrown into the cold palace and died tragically under the boning knife in his hand.

When she opened her eyes again, she was back to when she was ten years old. People are still the same people, things are still the same, but Fan Qingyao vows to turn things around!

For her seriously ill mother, her wasted sister, and her nameless brother, she wanted to personally find happiness and health for them, and a bright future ahead of them.

Stepmother who dominates her mother’s status, since you love money, I will keep you in poverty for the rest of your life.

Partial father, if you like power, I will ruin your reputation!

You scumbag who deceived her, you love the throne, I will let you watch others sit on that chair!

My sister with a hidden smile, everything you like, I will crush it to pieces in front of you with my own hands!

In this life, relatives must be protected and enemies must be fought. Of course, revenge is not avenged in a day, and the road is not completed in one day.

However, as this road of revenge continues, one more person appears out of thin air! Your Highness, could you please give way?
