Having many children brings many blessings; the struggle for power begins with marriage.

Lu Chen transmigrated to the Great Xia Dynasty and became the ninth prince of the Great Xia Dynasty.
Unlike the time travelers in novels, Lu Chen has neither extensive knowledge of science and engineering nor much memory of ancient poems.
In order to avoid getting involved in the struggle for the throne, Lu Chen had no choice but to lie low and plan to enjoy his wealth and luxury for the rest of his life in peace.
Because of his mother's status as a concubine, Lu Chen was eventually betrothed by the emperor and enfeoffed as a prince in the harsh northern lands.
Just when Lu Chen thought he was going to continue down this path of depravity for the rest of his life, the system was activated on his wedding night.
As long as he has a child, Lu Chen will receive a reward and also improve his own strength.
Years later.
Lu Chen led a million-strong army into the capital to defend the emperor, leaving everyone stunned.
"Isn't this guy a useless prince? Where did he get a million-strong army from?!"
"What's going on? He can actually be a Grandmaster?"
"So the Ninth Prince's downfall was all an act!"
