The story starts on earth, after some unknown circumstances, the world was suddenly invaded by monsters from other worlds. Many died and even more turned into zombies, starting what many would call 'The apocalypse Era'.

Upon meeting the girl who would become her adopted younger sister, the duke’s daughter Christina regained memories of her previous life. Through those memories, she learned that her new sister, Mishuli, was the heroine of a certain story. And though the story depicted a Christina who abused her sister, the real Christina turned into a siscon who spoiled Mishuli to no end.

Just became the disciple with the highest seniority, but the Age of the Dark Mist descended, and the sect plummeted into a land plagued with raging demons.

[Check-in at Training Ground, Success, acquired: Cultivation Base*50 years]

…

In the Age of the Dark Mist, demons were rampant, and an impenetrable mist veiled the empyrean. By vanquishing demons, the mist could be dispelled, and new check-in locations could be unlocked. By doing so clandestinely, Shen Changge became a Sword Saint.

When a demon broke into the Empyrean Sword Sect, everyone in the sect was powerless. People were in despair, until they met that young man in white who had just checked in at the Empyrean Peak. The young man’s eyes were ablaze.

“Submit, demon.”

Zhao Zhitong, who was still in kindergarten, took her parents and a family of three to cross the time-travel. As soon as she crossed, she was kicked out of the house by her cruel step-grandmother.

Looking at the only two cabbages in the family, Zhao’s father and Zhao’s mother looked sad.

Zhao Zhitong blinked a pair of Kazilan’s big eyes, and took out a bag of rice from the space with a bewildered expression…

So, the five-year-old little Mengbao took his parents to start farming, planting flowers, fruit trees, medicinal herbs, opening a shop, opening a restaurant…
