(1v1 Shuangjie sweet pet, so sweet! Shuangdatian) Shen Yaowei has been a fool who has lost his mind all his life, and finally was skinned and deboned by the person he trusted the most.

After being reborn, Shen Yaowei is no longer blind, nor is her heart blind, she just wants to hug the thigh of the future tyrant and be a rice bug that eats soft rice.

Possessing all-powerful skills and bearing the name of a foolish girl, Shen Yao secretly pretends to be a pig and eats a tiger, slaughtering the Quartet, and the abused scum cries for her father and mother.

Anyone who stopped her from hugging her thighs would have to die.

Soon, everyone discovered that the frightening highness of the King Rui, who had always been a loner, had changed, and there was always a small tail behind him.

“Uncle Nine Emperor… I don’t have the strength to walk anymore, I want to hug…” Little Tail stretched out his arms towards His Highness the Nine Kings, pitifully.

“Slim, big brother has strength, big brother hugs you!” The big brother, the leader of the martial arts alliance, arrived at the battlefield within a second.

“No no, the second brother is very strong, the second brother is here!” The second brother, who is a genius doctor, followed closely.

Next, the third brother, the fourth brother, the fifth brother… all the bigwigs came to the scene, begging for hugs.

“You all get out of the way for Lao Tzu! Lao Tzu’s daughter, Lao Tzu, come and hug me!”

Before the old father, who was a general protecting the country, had time to rush in front of Shen Yaowei, he saw that the aloof, dignified and peerless His Royal Highness was squatting with his back to Shen Yaowei.

“Come on, yaoyao, I’ll carry you.”

One day, I woke up only find out that I’d become a Demon Lord, an individual responsible for protecting a dungeon. The world I’d been spirited away to was one filled with violence. Gigantic monsters wandered through it and competed with each other each and every day for the right to survive. I had no choice but to strengthen my dungeon’s defenses in hopes of living another day—or at least that was what I’d thought. For some odd reason, I instead ended up spending my days in relaxation and bliss.
