Let Your Teacher Sister Teach Her How to Breathe Water?

My name is Lin Mo, and I have traveled through time. He became the chief disciple of the number one sect in the world of immortality, and a swordsman genius who has never been seen in thousands of years. Good news: he has a noble status, incredible looks, and a beautiful fairy fiancée. Bad news: I don't know how to practice at all, and I can't even hold a sword steady! In order not to be discovered, I hid on the top of a mountain in retreat, but Master brought me a cute little junior sister and asked me to teach her in person! I have no choice but to make it up. "Junior sister, do you want to practice swordsmanship and have a clear mind? Go and look at this stone until the end of time and realize the 'immovable mind'!" "Junior sister, want to practice supreme sword energy? Go, shout 'Demacia' ten thousand times to the sun, and understand the 'Light of Dawn'!" I thought she would quit in spite of the difficulties, but who knew... She actually practiced them all! Junior Sister: "Senior Brother, I have comprehended the 'immovable heart', a sword can conquer mountains and rivers! I have also comprehended the 'Light of Dawn', the sword energy is as bright as the sun! Senior Brother, you are really amazing!" Sect elder: "Chief Lin's teaching method is simply turning decay into magic, and the Tao is as simple as possible!" Looking at my junior sisters who admired me and the shocked sect, I hugged my "big deception" system and fell into deep thought. Is there something wrong with the minds of these people in the world of cultivating immortals?
