Xie Shi’an was bound by the “Return from Evil to Righteousness’” System 250, tasked with replacing the ungrateful children in every world who turned their backs on their families.

The familial love he had always yearned for—these heartless brats received it yet threw it away.

Rubbing his eyes with his chubby little hands, An’an vowed to turn over a new leaf and become the most well-behaved child for his parents.

In one world:

A deaf-mute couple raised their adopted son by collecting scrap, only for him to abandon them the moment his birth parents showed up.

Xie Shi’an, who had been picking up scrap with his father to support the family, was furious when his birth parents came knocking.

“Stay the hell away from me!!!”

In another:

A half-beast mother nourished her child with her own blood, only for him to grow up resentful, blaming her for “tainting” his bloodline.

But little Xie Shi’an, in the form of a tiger cub, clumsily caught a rabbit and piled it before his mother, nuzzling her with a soft “Awoo~” as he urged her to eat.

And yet another:

In a harem novel, the first wife sacrificed everything for her son, who despised her for not giving him a healthy body.

Xie Shi’an made it his mission to cheer up his mom, bring joy to his grandpa, expose his s*umbag dad, and help his mother find a second chance at love.

One-sentence summary: Turn over a new leaf and become the best child ever.

Strong murderous spirit, extreme personality, and alienated bloodline are the secret martial arts and magic. When horror comes quietly, when the world becomes strange, Li Xuan can only rely on the "attribute adder" and "bloodline bar".
