The Nine Swords of the Demon Gate, although the Xuanjian Master can also cultivate, but in fact, its effect will be greatly reduced, and it can be said that it is half the effort. On the contrary, if you practice with the sword of the Demon Gate Bone Demon or the Sword of Blood Evil, it is the most suitable and half the effort.

Moreover, the evil qi already has a certain restraint on the Xuanjian Master, and after the Nine Swords of the Demon Gate, it can even make the Xuanjian Master restrain his hands and feet, and the sword path will be damaged.

Of course, there are pros and cons to everything, and the method of demon cultivation goes against the sky, which is not tolerated by heaven and earth, so it is even more difficult, and most of them use killing as a shortcut, or practice in a forbidden place full of evil qi, which leads to them becoming a vulnerable group that everyone shouts and beats.

After Gu Zheng learned about the Nine Swords of the Demon Gate, his mind was floating, and he confirmed the inextricable connection between the Three Nine Xuangong and the Demon Gate.

Although he was not like the Bone Demon Hall and the Blood Demon Hall Demons, who needed to practice with the Bone Demon Qi and the Blood Demon Qi, the Sanjiu Xuan Gong brought him the most pure and strong evil qi, tempering a body that was better than that of the Demon and the Beast Clan.

The vigor of his blood and qi surpasses that of the blood demons of the same realm, and the strength of his bones is also better than that of the bone demons of the same realm. It's a pity that Gu Zheng has never had a way to fully play it.

Now seeing the inheritance of the Nine Swords of the Demon Gate, Gu Zheng seems to have opened another door in front of him, allowing him to peek into the application of his body.

As for the soul demon, Gu Zheng is powerless, what the people in the soul demon hall need is the foundation of the innate soul sword master, not manpower.

In the general outline of the nine swords of this demon gate, there is a method of condensing the evil sword, once the evil qi in the body becomes a sword, its power and magic are no less than the source of the heaven-sent sword.

Gu Zheng also noticed some of the speculations mentioned in it, the reason why the Demon Gate was born was probably because some predecessors who could not awaken the source of the Heavenly Sword went against the sky. Those people are not willing to live an ordinary life, so with great perseverance and determination, they have created such a road against the current.

Gu Zheng didn't know if this speculation was true, what he was most concerned about now was whether he could really condense his own evil sword.

If the sword can be achieved, Gu Zheng will be able to truly practice the Nine Swords of the Demon Gate, and he will also be able to fully exert the advantages brought to him by the Three Nine Xuangong.

As for the grievances and entanglements between the Xuanjian Master and the Demon Gate of the Heavenly Demon Palace, Gu Zheng didn't take it to heart. The sword is in the hands of man, and it is the evil that lies in man, not in the sword. This point, Gu Zheng has seen it very clearly a long time ago.

As soon as he thought of it, Gu Zheng did not hesitate too much and began to try.

The evil qi is different from the Xuan Li, which does not exist in the source of the dantian sword, but permeates the limbs and hundreds of remains.

What Gu Zheng has to do now is to mobilize all his evil qi, open up a space for storing swords in his heart, and then condense his own evil swords. The dantian of the people of the Demon Gate is not the vital point, but the heart.

This kind of unique means is absolutely difficult to achieve if it were not for the countless attempts and sacrifices of our predecessors. After all, the heart is the key to all people, and it is the basis for the flow of blood and vitality. The slightest carelessness is the end of physical destruction.

If there was no inheritance of the Nine Swords of the Demon Gate, Gu Zheng would definitely not dare to make such an attempt, and he would not even dare to think about it.

Now, Gu Zheng was sitting cross-legged on the ground, resolutely began to extract the earth-shattering qi from the hundreds of bones around his body, and slowly carried it towards his heart.

Impacting his heart with evil qi, Gu Zheng didn't dare to be careless, his divine sense sank into his body, staring at the changes in his heart.

The slightest cool and even gloomy aura converged into a stream of air, and under Gu Zheng's divine sense, it slowly approached the heart.

At the moment of touching, Gu Zheng couldn't help but gasp, he felt that his entire heartbeat had stagnated, and finally realized what it meant to be heart-wrenching.

This kind of pain is not even much better than the Soul Splitting Sword.

But Gu Zheng was secretly surprised, because he clearly felt that his heart really absorbed that wisp of earthly evil qi and did not reject it.

After the first step was completed, Gu Zheng was more sure, and he could even feel that his heart was more powerful after it resumed beating.

Immediately afterwards, Gu Zheng did not hesitate, endured the throbbing pain, and constantly carried the earth's evil qi, impacting and refining his heart.

The process was slow, at least in Gu Zheng's senses, as if life was like years, and he even gradually forgot the passage of time.

Until a certain moment, Gu Zheng suddenly felt that his mind was empty, and then there was a beating sound like a big bell, and the sound of dong dong was even and powerful, like an empty valley echoing, endlessly.

"It's done!" Gu Zheng blessed his heart, and his consciousness had sunk into his heart.

There, there was a dark space of its own, and among it was a three-foot long sword as black as ink, wandering uncertainly, constantly swallowing the earth-shattering qi in the limbs outside the heart.

As soon as the sword is completed, Zhou Tian operates, and the earth's evil qi can rotate on its own in the hundreds of bones of Gu Zheng's limbs, circulate endlessly, nourishing the muscles, bones and blood.

The predecessors once said that there was a flower, a leaf, and a world, but Gu Zheng now feels that the human body really contains a magical and infinite world.

At the same time, Gu Zheng felt a slight vibration in his dantian, and the five sword sources in it seemed to have encountered something terrifying, and at the same time, they shrank and condensed.

"This is the Sword of the Earth Evil!" Gu Zheng's consciousness returned, and with a move of his hand, a three-foot ink sword appeared in his hand, exuding a cold and incomparable aura.

This sword is different from the bone sword and blood sword of the demon gate, Gu Zheng has seen it with his own eyes, but at this moment, he feels that his evil sword is a truly complete magic sword, integrating the power of the bone sword and the blood sword, which has both its strength and strength.

The powerful and extremely fast beating of the heart gradually calmed down under Gu Zheng's control, and he felt that he could even completely control every beat of his heart, and he was no longer a bystander. This is a feeling that has never been felt before.

"The method of the Demon Gate really has its own uniqueness, especially the control of the body, which is by no means imaginable by the Xuanjian Master. Gu Zheng held the sword in his hand, feeling the subtle changes in every inch of his body, and was greatly excited.

"The sword has been completed, I can practice the Demon Gate Sword Technique, and the nine swords can be cultivated. Let's start with this sword technique. Gu Zheng's heart is surging, with the sword in hand, he is no longer restricted, the nine swords of the Demon Gate can be practiced, and it has the effect of getting twice the result with half the effort.

It's just that in this mountain-opening stone room, in addition to the general outline of the Nine Swords of the Demon Gate, there is only the inheritance of the mountain-opening sword technique, and Gu Zheng can only choose one of them temporarily.

The Nine Styles of the Mountain, aimed at the Yellow Dust Xuanjian of the Xuanjian Master, to be exact, aimed at the power sword intent of the Huangchen Xuanjian.

The nine-style swordsmanship is not complicated and difficult to learn, it is all a move that opens and closes, and the difficulty is to capture the traces of the power sword intent, and then exert the power to restrain the opponent.

From this point of view, Gu Zheng had a great advantage, because he himself had the Yellow Dust Xuan Sword, how could he not find traces of the sword intent of strength?
