Of course, Wu Wudi and Wu Runyue didn't know that the "Hunyuan Sword Sutra" that Chen Feiyu valued the most was not the sword moves, but his own sword intent.

It is said in the "Hunyuan Sword Sutra": "There is no better sword refining than qi, and the first thing to refine qi is to preserve the spirit." Therefore, the most important thing in practicing the Hunyuan Sword Sutra is to practice the sword techniques in it, to take the energy of heaven and earth, swallow the essence of the sun and the moon, cultivate the original sword intent of man, and then form the sword outside and the sword energy is prepared inside. Naturally, the strength will greatly improve. With one sword, you can draw the ground into a river and reach the extraordinary saint realm of "the body is invincible in the world, and the sword is completed by few enemy soldiers in the four seas".

Of course, with Chen Feiyu's own strength, the sword intent he inadvertently emitted was far from enough to cover the entire back mountain.

However, the "Hunyuan Sword Sutra" he practiced is both a sword immortal object, as well as the Longyuan Sword in "Yanling Hanging Sword Picture", so when he was practicing, it invisibly aroused the reaction of the Longyuan Sword, so that the powerful sword intent of the Longyuan Sword penetrated the "world in the painting" and was directly emitted, so that the entire mountain could be covered.

If there are people in the quiet room now, you will see the ancient Longyuan sword automatically emerge from the world in the painting, floating in front of Chen Feiyu, emitting endless sword intent.

However, Chen Feiyu closed his eyes and concentrated his mind. According to the operating route recorded in the "Hunyuan Sword Sutra", he constantly activates his true energy in his body and cultivates his own sword intent.

With the blessing of Longyuan Sword, his sword intent increased at a speed visible to the naked eye, and even the strong sword intent emitted invisibly made the entire back mountain silent, hiding one after another, and not daring to make a slight sound.

The entire back mountain is quiet, with only the late autumn wind remaining.

For three days, Chen Feiyu did not step out of the room and kept meditating and practicing martial arts to cultivate his sword intent. Just when his sword intent was accumulated to the peak, he began to try to break through the "Xuantong Orifice", one of the seven orifices.

Once this orifice is opened, the qi in his body will automatically run all the time, which means he is practicing qigong all the time, and even when he is sleeping, he will automatically cultivate the sword intent. In the future, he will enter the state of cultivation for a thousand miles. Therefore, opening up the "Xuantong Orifice" is the basis for practicing the "Hunyuan Sword Sutra"!

At this moment, Chen Feiyu condensed all the sword intent, as if a vast river was rushing violently into the "Xuantongkou" in his body, thinking that with the blessing of the Longyuan Sword, it could be easily opened.

However, the "Hunyuan Sword Sutra" is the real learning of sword immortals. With Chen Feiyu's strength in the "early stage of legend", even if he can barely practice, it would be difficult to open up the "Xuantong Ji" in just three days?

In an instant, Chen Feiyu's sword spirit was like a surging river and sea that encountered a mountain. It was blocked in an instant, and it was difficult to make any progress. Not to mention opening up the "Xuantongjiao", there was no reaction at all.

Chen Feiyu frowned slightly, feeling unwilling to accept it, so he controlled the sword intent and rushed away violently.

Several times in a row, all ended in failure without exception.

"I have accumulated such a powerful sword intent in three days and the blessing of the Longyuan Sword. Even Liu Hanxiao, who is in the "half-step innate" realm, may not be able to withstand it, but the "Xuantong Orifice" does not move at all, which is more difficult than climbing to the sky. I really don't know how difficult it will be to open the six orifices behind it."

Chen Feiyu opened his eyes and a trace of sweat appeared on his forehead, but an excitement flashed in his eyes. The more difficult it is to practice the "Hunyuan Sword Sutra", the more domineering he will be after he is practiced!
