Although the Ten Thousand Dragon Sword Technique was a top-grade martial arts technique, Jing Tianlong had clearly only mastered part of it.
Even though Jing Yan's Moon Cutting Sword Technique was merely an upper-grade martial arts technique, Jing Yan had managed to fix six out of the eleven flaws within it. Now, the power of the Moon Cutting Sword Technique was almost comparable to that of ordinary top-grade martial arts techniques.
Therefore, even though Jing Tianlong wielded a weapon that was one grade higher than Jing Yan's and his Primordial Energy was much thicker, he still found it difficult to defeat Jing Yan's Moon Cutting Sword Technique.
Another point was that although Jing Yan couldn't pinpoint the weaknesses of the Ten Thousand Dragon Sword Technique in a short period of time, he had a rough feeling of it. With deliberate control, he could also conserve a lot of energy while using the Moon Cutting Sword Technique against the Ten Thousand Dragon Sword Technique.
