I'm Her Favorite Character - Chapter 12 - : Eye am not paying for this

A man is reborn into the world of Avatar: The Last Air Bender as a waterbender from Katara's tribe. Best of all, he was the same age as her, and he had a system with him to help.He knows the future and a system that lets him continuously get stronger by completing quests or long-term missions, as well as giving him the ability to copy abilities from others for himself. He will become invincible in the world of Avatar, even more so than the Avatar himself.

In the Celestial Empire, a land ruled by Immortals and stalked by Spirits and Beasts, a young girl from the slums of an unimportant city is found to have the Talent. In the great Sect of Argent Peak, she will take her first unsteady steps upon the way.

Liu Sanniang was reborn. When she remembered her lonely end, she decided to get married in this life no matter what.

She only wanted to marry an average scholar, but who knew that the tall and striking future general, Chu Yan, took an interest in her.

The first time they met, she was too shy to look up at him.

The second time they met, he sandwiched her against the wall and said, “Are you afraid of me?”

The third time they met, he squatted down and said, “Come on, I’ll carry you.”

***

After meeting a few more times, he came to ask for her hand.

However, he was at least two meters tall and muscular. She feared that he might squash her to death!

Once they got married, Chu Yan strode over to her and ‘forcefully’ grabbed her hand, ready to pass his life savings to her. Yet, his delicate and beautiful bride fainted out of shock…

Liu Sanniang then realized that being with her ‘scary’ husband meant living peaceful and leisurely days, so her eyes narrowed as she grinned.

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!
