All My Masters Want Me, but I'm Hopeless at Cultivation

Su Chen transmigrates into a fantasy world and, from the start, becomes the only male disciple of the Ethereal Sect, with four stunning masters at his side! The eldest master is aloof and chaste, lofty and untouchable, but secretly a total masochist~ The second master is charming and alluring, always thinking about how to devour him whole. The third master is gentle, pure, and unstained by worldly things. All she wants is to fall in love with him. The fourth master... is unbelievable! She likes her senior sister! It should have been a perfect start, but he has no talent for cultivation and is a complete good-for-nothing! Luckily, Heaven rewards hard work: for every bit of effort, he gets a ten-thousandfold critical hit! While others fly on swords, he practices horse stance. While others temper their bodies, he trains his iron waist. Is an ordinary mortal body too weak? Strike a post a thousand times, and an ordinary waist becomes an iron waist of diamond, impervious to blades and spears! Are low-tier sword skills useless? Draw your sword ten thousand times and become a sword master, able to break ten thousand techniques with a single strike and kill anything instantly! Who says low-tier martial arts can't kill an immortal? Gradually, Su Chen realizes that the way his four masters look at him is getting more and more suspicious. Eldest master: “Disciple, you can be... a little stricter with me...” Second master: “Come to my cave tonight. Your master will teach you a marvelous technique.” Third master: “Good disciple, your master... your master wants a hug...” Fourth master: “??? Wait, why am I swallowing nervously?”
