Defeat the Iceberg Sword Master Who Killed Me

If he fails, he will die on the spot. (I would really appreciate it) The system task is coming: ["Accidentally" scratched by his sword energy. I touched the porcelain with trepidation, and he healed my wounds with a cold face. When his fingertips touched, his hands shook. Me: "Uncle Master, why are your hands so hot?" Him: (stopping hastily) "... You talk too much." The system task comes again: [Kiss the side of his face while "sleepwalking". I was nervous about performing the whole set, but he suddenly opened his eyes and grabbed me, his ears were so red that they were about to bleed. Me: "Uncle Master, I seem to be dreaming..." Him: (gritting his teeth) "... Go back to sleep!" The system task came again: [Copy his sword moves in front of him. I gestured with a branch, and for the first time, he came out in person and held my hand from behind to teach me. Me: "Uncle, your heart is beating so fast." Him: (fleeing) Everyone: "Sword Master's sword heart... Is in chaos!" No, what about the ruthless way we promised? Is the difficulty of this guide a bit too low? !
