I, the immortal black serpent, reside in Ursus, a young and promising immortal. I lack the overwhelming power of monstrous calamities, the potent corruption of demons, and the boundless adaptability of the Sea Child. Though I possess strange memories, I am certainly not as old as my predecessors. My only dream is to die a peaceful, natural death. I adopted a simple-minded child who constantly opposes me and urges me to join her in her demise. I befriended a reclusive pen pal who likes to send me landscape paintings, but I always feel she's out of touch with the times. I met a goofy hunter who asked me for [a cool pen].

We all know the process of a normal person traveling through time...but...it seems...something is wrong?

Traveled to Terra.

"I was born today as the thirteenth girl of the year. After wandering for a thousand years, I learned that my true name is Jiu."

"I know that I am the blood of a criminal, and my sins are deep. I have set aside a hundred years to perform good deeds and provide medical care to all living beings to atone for my remaining sins."

Looking at the dragon sons not far away who were staring at him because of his unexpected birth on the 13th of the 13th month, and the dark mass of imperial guards further away, Jiu spoke tactfully.

From then on, the filth of the world, the resentment of the Sui beast, and the legendary journey of the Royal Aunt of Yan Kingdom officially began!

"Where do all these conspiracies and riddles come from? This is definitely a relaxing and enjoyable day~"

"Look at what you said, do you believe it?"

“I promise (๑´∀`๑)”

The protagonist Mona is a young person of the new era. By chance, she travels to the Arknights, the world of Terra.

Life was good, I had found something I loved, and I had a place to call home.

It’s just that I feel like this place is involved in too many things, and I always get involved in some weird things.

Mona: Mom, I want to go out and have some fun!

Kal'tsit: ...

Mona: Doctor Kal'tsit? Boss Kal'tsit? Kal'tsit! Kal'tsit's mom!

Kal'tsit: No, you've been to the medical department seven times this month. We can't let you out again!

Mona: QAQ
