When Chen Fei initially perfected the Zhongyuan Sword, he could already completely gather the power of the Zhongyuan Sword onto the blade.
At this point, the Zhongyuan Sword could already unleash its immense strength, demonstrating the combat level that this heritage should possess.
Now, Miao Daoxin is also practicing the Zhongyuan Sword. He's currently at this position, or rather, slightly more advanced than this stage, but not yet at the true peak, which is the stage of Great Completion.
Some time ago, Chen Fei refined the Zhongyuan Sword to the stage of Great Completion and discovered that he could further condense the sword's power, focusing it only on the edge of the blade.
