An unnamed 34-year-old Japanese NEET is evicted from his home following his parents' death.

Upon some self-introspection, he concludes that his life was ultimately pointless.

Walking down a street he intercepts a speeding truck heading towards a group of teenagers, in an attempt to do something meaningful for once in his life he manages to pull one of them out of harm's way before getting himself in the way of the truck and dying.

Awakening in a baby's body, he realizes he has been reincarnated in a world of sword and sorcery.

He resolves to become successful in his new life, discarding his past identity for his new life as Rudeus Greyrat.

Big news! Big news!

The people of Qingzhou spread the word to each other.

After 200 years of not having any daughters, the Jiang family of Xijin Ferry has finally given birth to a baby girl.

Legend has it that this baby girl was born with great good fortune.

On the day she was born, the long drought-stricken land was blessed with sweet rain.

A few days after she was born, when her elders went up the mountain to hunt, they found a huge spiritual mushroom, resolving the family’s urgent need.

Half a year after she was born, her father topped the imperial exam and was appointed as the top scholar, bringing glory to their ancestors. After becoming an official, under the blessings of little darling, he successively grew new high-yield grain varieties that yielded thousands of catties per mu, shocking the world. It was smooth sailing all the way as he rose through the ranks.

The noble lords looked at Jiang Yuqing subtly gaining favor from the Emperor on behalf of his father, and then at their own daughters who only knew how to fight for attention and be jealous. Tears of envy flowed from the corners of their mouths.

Jiang’s father weakly raised his hand: I swear I didn’t teach her that, do you believe me?

The lords: Tsk…

Seeing the little girl become more and more outstanding, drawing a frenzied swarm of admirers, a certain prince was finally enraged, his sword sweeping across and leaving blood flowing like a river: A flower raised by me, how dare you!

500 years ago, Chen Xi was devoured by a crack in the void and was transported into a cultivation world.

500 years later, he returned back to Earth after enduring through several hardships and discovered that only 5 years had gone by.

…

In the courtyard, beauty at the side, a candle flame wavering.

A gush of clear wind, half a full moon, the peach tree remains unchanging.

…

Wait, whose kid is this?! Why is she calling me papa? Gazing at the little girl in front of him with skin as pale as jade, Chen Xi froze.

…

　
Returning home from cultivation, starting as a stay-at-home dad.

In this life, not fighting to be a king nor claiming to be a tyrant, only praying to peacefully be a wife-pampering mad devil and a child-protecting daddy!
