In the center of the secret room, Zuo Chen carefully looked at the knife body in front of him.

This soul cutting knife is really not simple, there are ancient lines on it, and the depths of the lines are bloody, as if it is the "meridian" of this knife, once it is crossed by its own Gu Yuan force, the entire knife body immediately bursts out with a bright light, and before it has been used, it seems that there is a kind of sword intent that sweeps the world and spreads out.

"It is worthy of the weapon left by the Dao Ancestor back then, it is really extraordinary and powerful. Zuo Chen muttered.

This knife may not be as good as his own Ten Fang Heavenly Monument, and it may not be as good as the Qiankun Demon Refining Tower, but once this thing is born, it is also a treasure that will cause countless people to compete for it. The cloud chaotic is holding the soul cutting knife, it is simply swaggering through the market, wanting to kill himself, and being killed by himself is also sad.

From the return of the Eight Poles Mountain Range to today, all kinds of things are complicated, Zuo Chen does not have extra time to refine this knife, today is the time.

A moment later, the Ten Directions Heavenly Monument also manifested, Zuo Chen's hands were sealed, and at the same time, the telekinesis covered the Ten Directions Heavenly Monument and the Soul Cutting Knife, and began to refine on the spot.

This soul-cutting knife seems to contain a kind of will, it is a very unique, very strong knife intent to repel Zuo Chen, this knife has a means of self-protection, to avoid being easily refined. But unfortunately, with the suppression of the Ten Heavenly Monuments, the will within the knife body disappeared without a trace in the blink of an eye, and it was impossible to compete with the Heavenly Monument at all.

Time was passing, and the blade body was constantly refined by Zuo Chen, and after a day had passed, the soul cutting knife had completely turned into a piece of waste, leaving only residue, and it was impossible to see what it used to be.

He knew that this Soul Cutting Knife had been successfully refined by himself with the Ten Heavenly Monuments, and as for what he originally envisioned, it could be realized, and it was all fate.

Zuo Chen's eyes showed a light of expectation, he stared at the Ten Heavenly Monuments at this moment, and then his mind worked, and his eyes were locked together.

His telekinesis communicated with the Ten Directions Heavenly Monument, and at the same time, in Zuo Chen's mind, a void and empty world appeared, and in the central heaven and earth of that world, a sword body condensed at will.

He was communicating with the Ten Heavenly Monuments with his own will, hoping to make the Heavenly Monument "turn into a sword", just like the Heavenly Monument turned into a sword after refining the Demon Sword.

Gradually, a wisp of sword intent appeared out of thin air in this secret room, this sword intent just appeared and was not very powerful, but as time continued, it became more and more intense, and in the end, it was simply surging, like a storm sweeping through this secret room.

If it weren't for the fact that there was already an extremely extraordinary rune array in this place that isolated all the aura, I'm afraid that the sword intent would have spread through this place a long time ago.

Suddenly, Zuo Chen's eyes exploded, and under his gaze, the shape of the Ten Directions Heavenly Monument in front of him began to change, shrinking and distorting, and finally, a brand-new knife body appeared in front of Zuo Chen's eyes.

This knife, simple and atmospheric, is exactly the form of the knife that Zuo Chen imagined before, exactly the same as it.

The body of the knife exuded a powerful aura, and a terrifying sword intent spread out, which was extremely amazing. Zuo Chen felt that there was a blood-blended connection between himself and this knife, and with a single thought, this knife body could be slashed out at will, and it was simply his own natal weapon.

This knife is made of the Ten Heavenly Monuments, Zuo Chen can naturally control it at will, it is about because he has been cultivating the Shura Flame Knife for a long time before, and he has a sense of familiarity, Zuo Chen feels that he is holding this knife, and it is stronger than the sword that has evolved from the Heavenly Monument.

"The Heavenly Monument has been successful, and the next ...... is coming. Zuo Chen held the knife, and the excitement in his eyes flashed.

At the same time, the rune ring in his hand flashed with a glow, and then an item appeared.

At a glance, this is also a knife, the difference is that it is extremely weird, because this knife has no blade, flashing with a sky blue brilliance, like a dream, at the same time, there is a knife body, countless runes are flickering, it seems to be a world of its own, countless dense runes condense with each other, exuding a mysterious and terrifying atmosphere.

"Sword Soul!" Zuo Chen muttered, spitting out two words.

This thing was the reward he received when he was in the Firmament Domain, and he became the first person in the Imperial War: the Phantom Soul of the Sword.

As the name suggests, this thing is blessed on a knife, as if it is blessed with a "soul" similar to that of a Yuan martial artist, and if a knife has a soul, then the power will enter a new level, with unimaginable and amazing changes.

Night 6 has been born in four generations since ancient times, with a total of sixteen weapon phantoms, each generation of weapon phantoms is a sword soul, a sword soul, a gun soul, and a spirit phantom that can be fused with any weapon.

The sword soul he obtained, if nothing else, should be the second generation of the four generations of weapon phantom souls: the sword soul of the "Frost Phoenix Flame" martial soul.

Since the birth of the big 6 weapon phantom soul, I don't know how many yuan warriors have frantically competed and sought after, and among the four generations of sixteen weapon phantom souls, the most popular is the sword soul in the second generation of phantom souls, the sword soul and the gun soul ...... in the third generation of weapon phantom souls. Zuo Chen was naturally no exception, holding this sword soul, he was still very excited, and at the same time had great expectations.

This weapon phantom soul is not only equivalent to the "soul" of the weapon, but also equivalent to giving the weapon a rune battle armor similar to that on the Yuan Warrior, which has unimaginable benefits. Integrating this sword soul into this sword is equivalent to making your Ten Directions Heavenly Monument stronger, and when it comes to the real battle, I don't know what kind of extraordinary effect it has?

This sword soul does not need to be refined by Zuo Chen, it only needs him to use his mental power to make the sword soul and the knife body merge with each other.

However, half an hour passed, and the fusion of the two was completely completed, the sword soul disappeared, and in its place, the knife in Zuo Chen's hand had undergone an extremely extraordinary change, the edge was concealed in the dark, and there was a sky blue streamer flickering on the surface of the knife body, and every ten breaths or so, there would be a light and shadow flashing from it.

Zuo Chen looked at it carefully for a long time, and said unexpectedly: "In the sword soul, could it be that there is a phoenix soul hidden in it?"

No matter how he looked, the light and shadow seemed to be a phoenix flashing away, extremely extraordinary and weird.

The fourth-generation weapon phantom soul of the dark night big 6, the first-generation weapon phantom soul is called the "scorching dragon soul", and the sword soul that he got belongs to the second-generation phantom soul, which is called the "frost phoenix flame phantom soul", could it be that there is really something hidden in it that he doesn't know, and the birth of several weapon phantom souls such as the scorching dragon soul was formed by refining the soul of the real dragon?

However, there was no point in thinking about these things, Zuo Chen's thoughts flashed away, and he directly converged.

He held the battle knife in his hand, and he had the urge to directly slash out with a knife, wanting to try the true power of this knife, but after all, this was his own cultivation secret room, and it was not suitable for drills, so he could only talk about it later.

Soon, under the operation of Zuo Chen's mental power, the war knife in his hand once again turned into the original form of the Ten Directions Heavenly Monument, and after returning to the form of the monument, the azure light and the phoenix light and shadow all disappeared, and there was no trace of abnormality.

"Very good, since ancient times, there are many Yuan martial artists who are chasing frantically, and I want to get the four generations of sixteen weapon phantom souls, I'm afraid it's not for no reason, now I can really refine this sword soul, and then I can reflect its power in battle. Zuo Chen took the Heavenly Monument into his body and said in a low voice.

Today's Zuo Chen, the Nine Apertures Immortal Body has entered the fifth level, and his physical body is vigorously outclass, especially with the blessing of Gu Yuanli, the power of one punch is probably not too much to shatter the heavens and the earth, it is incredible, and his mental power has improved with his own strength, and he already has the strength of a real master of the US Dollar Body Realm, coupled with the strength of his own soul, and today he has refined this sword soul, and now even Zuo Chen himself can't imagine what kind of transformation his strength has had in these days.

Last time, he was already able to confront the characters of the Fifth or Sixth Heavens of the Martial Soul Realm, and now, Zuo Chen has a feeling that even if the Eighth Heaven of the Martial Soul Realm, or even the masters of the Ninth Heaven want to fight with him, it will be difficult to suppress himself, right?

Before, the strongest of the eight masters hidden in the War Academy of the Yun Clan was the existence of the Eight Heavens of the Martial Soul Realm, Zuo Chen tried, with his own strength that day, although he was not weaker than that master in terms of mental power and soul, and the strength of the physical body, but when it came to really starting a move, there was still a big gap, and it had to be suppressed. But now, that gap seems to be being bridged unconsciously.

"Very good, now my strength has skyrocketed, with more means of self-protection and fighting, and the foundation is stronger, even if the so-called chaos appears soon, there are really strong people of the Yun Clan, including the forces of other ancient worlds, once the battle starts, I will no longer be as powerless as before, at least I can barely fight with any master under the battle spirit realm. Zuo Chen thought secretly in his heart.

Zuo Chen is only a mere realm of the Five Heavens of the Mysterious Transformation Realm, but he has such an incredible strength, even if an ordinary genius can fight beyond his own height, it is impossible for Zuo Chen to cross the law. If this is spread and known by other Yuan Martial Artists in the future, it will definitely be extremely shocking. But not ...... , Zuo Chen himself is not proud, he knows that compared to the truly terrifying existence, this is nothing at all, he is still like an ant, without the power to resist. More and more ...... are needed to improve the strength.

"Now, the several Gu Yuan techniques that I have cultivated, Master, have basically been completely completed, just like the Shadow Blade, the Shadow Clone, the Nether Ghost Slash, and so on, all of which are extremely proficient. It should be a new Gu Yuan Technique, but I was told that if I completely control these three Gu Yuan Techniques, I will have the opportunity to comprehend a new method: the Instant Hell Shadow Killing Array, which is the real Great Killing Technique, the more powerful it is, it is unimaginable. I really wanted to cultivate that Instant Hell Shadow Killing Array, but I still have no clue, could it be that my control over those three Gu Yuan Techniques is still insufficient?" Zuo Chen then thought of something.

Just as he was thinking, the rune array in the cultivation room suddenly started to work, disrupting Zuo Chen's thoughts.

"The rune array operates autonomously, is this someone looking for me outside?" Zuo Chen looked outside the secret room, and then he gathered his breath, and with a wave of his big sleeves, he was about to open the secret room.

"Purple shirt?" Zuo Chen saw that someone was coming, and it was Chen Zishan who came to find him.

"Oh no....... The first time he saw Zuo Chen, Chen Zishan directly spit out three words.
