The Thunderbolt Sword-Drawing Technique was used to advance rapidly and defeat the enemy with a single move.
Of course, it was impossible to kill Yan Yu'er with the Thunderbolt Sword-Drawing Technique alone. Even if Lin Yao trained this combat skill to great success, or even if Yan Yu'er let down her guard because Lin Yao was merely an intermediate martial artist, she'd still have a certain chance to react. She was, after all, a powerful advanced martial artist.
However, the foundation of any martial artist was their physical fitness. There was no doubt that the stronger their physical fitness was, the greater the power of their combat skills would be.
When physical fitness reached a certain level, even without using any combat skills, the opponent could be crushed by strength alone. As people said, a powerful man could defeat ten people with martial arts skills.
