The Turtle Son-in-Law's Rise

I wasn't a lecher, but the System left me no choice.

The protagonist obtains a Foolish Old Man System that lets him produce as much as he wants, as long as he cultivates with all kinds of lovely women in the real world.

This System is a bit hard on the back...

The protagonist, Ye Chen, is the lowest-ranking live-in son-in-law. Every day, he's responsible for working the fields for the young lady of the Yao family and helping her produce an heir. But Old Wang, Old Zhang, and Old Li are involved too. A son-in-law has no dignity, so he decides to use the System to turn it all upside down.
