Why Is This Swordsman so Meaty?

Lu Ling accidentally traveled to the world of cultivating immortals and obtained the prop "Steel of the Heart". This piece of equipment allows his health to grow infinitely. When he first became a disciple of the Sword Immortal, he imagined that he could become a handsome sword cultivator, fly with a sword, unite ten thousand swords, and open the gate of heaven with one sword. Unexpectedly, as the blood volume of "Heart of Steel" increased, he became more and more like a crude physique who could only fight with his fists. "No! My path to immortality shouldn't be like this!" Lu Ling made up his mind to become a suave and powerful swordsman. . . . . . . A few years later, facing his tired enemy who collapsed on the ground, Lu Ling said calmly: "I stood and let you fight, but you couldn't fight. I gave you a chance and you were useless!" Sword cultivators can only kill each other instantly, but only physical cultivators can experience the joy of being wiped out even in battle! I won't practice swordsmanship anymore!
