I Married My Senior Sister and Created a Hundred Desolate Heaven Emperors

After transmigrating to a fantasy world, he spent thirty years failing to establish his foundation. His constitution was terrible, his meridians were destroyed, and ascension was out of reach. Chen Xuan decided to simply elope with his fellow disciple, the senior sister, and get married! But Why did the System suddenly awaken on their wedding night?! Getting married and having children brought him rewards by the handful! Every child born was a peerless genius! As his children cultivated, his own cultivation improved too! With more children, more blessings: the more descendants he had, the more fortune he gained! And so His descendants spread throughout the heavens. Only then did the world realize that Chen Xuan had long since become an immortal through countless unions!
