As a new employee of the Space-Time Administration, Gu Chaoxi's task is to give birth to children for the male protagonist who has no descendants in different worlds to change their childless ending.

World 1: The arrogant daughter of the Marquis's mansion x the powerful and childless regent (double clean semi-immersion)

The little emperor fell in love with the arrogant and beautiful daughter of the Marquis's mansion and begged the regent to propose marriage. The regent, who has always been calm and self-reliant, nodded in agreement, but on the day of the wedding, he kidnapped the bride and trapped her in a separate courtyard.

World 2: The long-lost real daughter x the blind and lame prince (double clean immersion)

The prince of Yongyi Marquis was blind and lame, and was forced to marry the daughter who had just been found in the Pyeongchang Earl's mansion.

On the wedding night, he handed over a letter of divorce, but suddenly withdrew it after smelling the body fragrance of the other party.

Smell the fragrance to know the person.

World Three: A beautiful noblewoman bent on revenge x a cold-hearted and impotent emperor (double-clean immersion)

Chu Xiao has been on the throne for many years, cold-hearted and cold-hearted, and none of the concubines in the harem are pregnant, just because he is impotent. Until that night he met a beautiful woman, knowing that she was using him, he was willing to sink step by step.

World Four: Princess of Peace x Prince's substitute (double-clean semi-immersion)

Yan Zhaoxi is the least favored princess of Dongqi State. She was ordered to marry to Daliang for peace and became the prince's concubine.

One night, there was a knock on the door: Sister-in-law, open the door, I am my brother.

( Just bear the 1st arc. Gets better in later arcs.)

Her mother died, her father favored his concubine over his wife, the prince of a marquisate broke off the engagement in public, and Ji Yunhuan nearly lost her virginity and was thrown into a nunnery to fend for herself.

When she was on the verge of death, she was bound to a child-bearing system.

As long as she entered the palace and gave birth to an heir for the emperor, she would gain supreme status.

She would not let go of any of those who had bullied her!

[1] Beautiful daughter of aristocratic family vs. middle-aged emperor with no heirs

[2] Daughter of a guilty minister who was demoted to a prostitute vs. moody disabled prince

[3] Spoiled and vicious female supporting role vs. misogynistic childless emperor

[4] Scheming maid who climbed onto the dragon bed vs. irritable emperor who was poisoned and childless (double rebirth)
