Quick Transmigration: After the Fertility System Takes Hold, Zhizhi Becomes His One and Only

[Exclusive devotion to one another + one-on-one romance + no rivalry between women]

Zhizhi, an office worker who died suddenly from overwork, unexpectedly arrived in the void and bonded with System No. 19816 from the Space-Time Administration.

Have a child! Save the chosen one of each world! Accumulate energy to exchange for points! And bring back gold and silver from every world!

And so, the worlds began in a daze...

A disabled crown prince, a young aristocratic uncle abandoned by his family, a puppet emperor controlled by officials, a loyal little guard serving an empress...

As the System appeared in each world, Zhizhi realized she always seemed to receive the same pair of bracelets from her mission targets...

What could this possibly mean? What secret was the System hiding?

Who was playing the mission targets in each world?
