Lend Me to Continue the Family Lineage? I Bind the Goddess Invincible with My Backhand

"I'm your boyfriend, and you want me to have a baby with your aunt?" The era of high martial arts has arrived, the earth has risen in dimension, and the ancient road in the starry sky has opened. Lu Xun was an ordinary student, but because of the request of his school beauty girlfriend Chu Youqing, he was involved in a "child seeking" controversy. "Lu Xun, please, help my aunt!" Chu Youqing begged pitifully, but her aunt was actually the most beautiful woman in Chengdu - Murong Wan! Lu Xun wanted to refuse, but by mistake, he had a ridiculous night with Murong Wan! This accidentally activated the return system. After binding Murong Wan, as long as she practices, Lu Xun can get ten times the return! "Murong Wan awakens the Linglong Treasure Body, you will receive ten times the return, and awaken the Chaos Divine Body." "Murong Wan breaks through to the Grandmaster realm, you will get ten times the reward and become a Grandmaster." From then on, Lu Xun embarked on a journey of becoming stronger from a humble position.
