"Watch closely!"

    Chen Tiansheng called out, then punched toward the front.

    "Boom!"

    A loud explosion occurred, and a three-meter-tall artificial hill ten meters ahead suddenly blasted open.

    Xu Nian and Chen Yao immediately widened their eyes, their faces showing disbelief.

    How could that punch have exploded an artificial hill from a distance without Chen Tiansheng using any Spiritual Energy?

    "Did you both see clearly?" Chen Tiansheng turned, smiling at Xu Nian and Chen Yao.

    Both of them shook their heads.

    They didn''t understand how Chen Tiansheng had managed to do that.

    "Actually, it''s very simple. Whether it''s Sword Qi, Fist Formation, or Saber Force, they are all ways of harnessing the forces of nature. What I did was use the forces of nature to create pressure on that artificial hill, causing it to burst," Chen Tiansheng explained with a smile.

    "Force of nature?"

    Xu Nian looked thoughtful, while Chen Yao still appeared confused.

    "Talking about the force of nature might still be a bit premature for you now. You have only just begun to understand ''Man and Sword as One.'' Yet, you haven''t grasped the Three Levels within it. Once you comprehend these Three Levels, you''ll understand what the force of nature is," Chen Tiansheng continued.

    "''Man and Sword as One'' has Three Levels? What are they?" Chen Yao asked.

    Xu Nian also looked at Chen Tiansheng. This was the first time he had heard such a thing.

    "The Three Levels within ''Man and Sword as One'' are Sharp Sword Cutting Hair, Wooden Sword Cutting Stone, and Finger Sword Breaking Gold," Chen Tiansheng said smilingly.

    "Huh? That doesn''t sound difficult. Isn''t cutting hair with a sharp sword fairly easy? And cutting stone with a wooden sword, anyone who has reached the Battle Sect Level should be able to do it. As for Finger Sword Breaking Gold, that doesn''t sound too challenging either," Chen Yao remarked.

    Xu Nian, however, shook his head. These Three Levels were probably not as simple as Chen Yao thought.

    Firstly, Sharp Sword Cutting Hair was not about chopping the hair off. It meant slicing a strand of hair in half, which required the sword to be incredibly fast, accurate, and powerful.

    Secondly, Wooden Sword Cutting Stone was not that simple either.

    Firstly, one cannot infuse Spiritual Energy into a wooden sword as the soft wood cannot hold it and would burst. Therefore, to cut stone with wood, one must precisely control their internal power.

    Neither too much nor too little.

    Almost impossible to control!

    Seeing her father leaving, Chen Yao took out her sword and began trying Sharp Sword Cutting Hair.

    However, her eyes couldn''t keep up with the speed of her sword; no matter how she swung, she would always end up cutting crookedly.

    Xu Nian did not rush to try but sat quietly, recalling every detail of Chen Tiansheng''s demonstration.

    Time passed quickly, and Chen Yao had practiced hundreds of times; however, she couldn''t even align with a hair tip.

    Just then, Xu Nian, who had been sitting still, suddenly stood up to make his first attempt.

    "Swoosh!"

    Xu Nian swung his sword fast as a phantom, instantly slicing a strand of hair, although the lengths were not equal.

    It turned out that although Xu Nian hit the hair tip, he failed midway.

    Nevertheless, just this was enough to make Chen Yao''s eyes bulge like an ox.

    She had practiced hundreds of times here without touching a single hair.

    And here was Xu Nian, who had just sat for a while, and already he had succeeded halfway.

    However, Xu Nian was extremely unsatisfied. The instant earlier, he had used Gray Dragon Eye to instantly capture the trajectory and tip of the hair, enabling him to cut it with one stroke.

    But during the middle phase, when he wanted his sword to follow the trajectory of the hair and split it in two, he could not manage it.

    "No, it''s not about the eyes, but the heart; heart integrating with the sword. Only by controlling the sword with the heart can one perfectly slice through the hair," Xu Nian suddenly thought of Chen Tiansheng''s words as he left and immediately realized that using Gray Dragon Eye just now had been a mistake.

    So, this time, he suppressed his Gray Dragon Eye, relying entirely on his heart to control the sword in his hand.

    Of course, the final result was quite obvious; he failed, not even hitting the hair tip.

    "Pfft, it was just good luck, you had me scared for a moment. I thought you had grasped it just by watching," Chen Yao muttered, feeling much more at ease.

    Xu Nian helplessly shook his head. This time, he simply closed his eyes, allowing his mind and sword to completely merge.

    "Hum!"

    Xu Nian abruptly opened his eyes, his gaze fierce.

    Once again, he swung his sword: the blade swept through the void.

    A foot-long strand of hair was directly cut into two halves by him.

    "How... how is this possible?" Chen Yao''s mouth dropped open, completely stunned.
