Lu Ming transmigrated to the immortal cultivation world. Due to his exceptional good looks, he was picked up by the fairy Su Hanyi, who was traveling through the Dao realm, and became the founding first disciple of the Yanxia Peak of the Tianyan Sect. However, he is a mortal who is a waste of five combat points, and his only cheat is an invincible domain in the yard that grows by one centimeter every day. He originally wanted to lie flat until his master returned, but who knew the sect leader would shove over a junior sister with mediocre talent, Lin Qingyao. However, feeding the junior sister a bite of a chicken drumstick makes the domain surge by one centimeter! Giving the junior sister a word of guidance on a cultivation technique makes the domain expand by one meter! Lu Ming figured it out: isn't this just letting him play at raising a junior sister!
