Five hundred meters later, Wu Chi suddenly had a feeling of enlightenment!

Under Longtan, it is far more expansive than imagined, but the pressure is much more terrifying than before.

Once the line of five hundred meters is surpassed, even the power of the star field cannot stop the infiltration of Long Wei at all, and in an instant, with the strength of Wu Chi's body, there are already blood seeping out of the pores, and what is even more terrifying is that the terrifying Long Wei is directed at the soul, and even makes Wu Chi have a feeling that his soul will collapse if he does not retreat.

However, Chengying Sword still dragged Wu Chi to continue diving.

Six hundred meters, seven hundred meters!

The pressure on Wu Chi is getting bigger and bigger, and the blood stains on his body are not only pores, but also ears, nose, mouth, and eyes...... It seems that blood is oozing out everywhere, and this is the real bleeding of the seven orifices.

At this moment, Wu Chi could clearly feel that he could no longer continue to go down, otherwise he was afraid that he would really die under this dragon pool.

With a sudden pull, Wu Chi forcibly stopped the falling momentum, and slowly injected star power into the Chengying Sword, trying to appease the restless Chengying Sword.

Feeling Wu Chi's will, the Chengying Sword trembled, and seemed to have sensed that Wu Chi had reached the limit, however, there was still unwillingness in the Chengying Sword, and in a moment, a terrifying sword intent suddenly burst out from the Chengying Sword, directly protecting Wu Chi!

Before Wu Chi could even react, the Chengying Sword suddenly dived again under the wrapping of this sword intent, and the speed was much faster than before!

Eight hundred meters, nine hundred meters!

It wasn't until this moment that Wu Chi really saw the bottom of the Tan clearly, and roughly estimated that Longtan should only be about a kilometer, and what attracted the Chengying Sword to dive frantically at the bottom of the Tan was a huge skeleton!

The flesh and blood had long since decayed and disappeared, and now all that remained was a skeleton, but this skeleton alone was hundreds of meters long!

Vaguely, I could see that this was the skeleton of a dark dragon.

The terrifying dragon breath and dragon power in the dragon pool are also revealed from this skeleton.

I am afraid that this dark dragon has been dead for many thousands of years, but the residual power is still so terrifying, if it weren't for the sudden explosion of that terrifying sword intent from the Chengying Sword, Wu Chi wouldn't even be able to see this skeleton at the end of the day.

This scene is also a huge shock for Wu Chi!

However, what really shocked him was still behind!

The Chengying Sword was not satisfied with seeing this skeleton, but was wrapped in sword intent and stabbed towards the skull of the Dark Dragon Bone!

"Whew!"

In an instant, the terrifying sound of the dragon's groan suddenly exploded in Wu Chi's soul, and in an instant, Wu Chi actually had a feeling that his soul was about to be drunk, as if even his consciousness was a little blurred.

However, the Chengying Sword was not affected at all, and dragged Wu Chi into the skull of the Dark Dragon!

Rumble!

The moment the Chengying Sword pierced, it seemed that the entire skeleton trembled, and the entire Dragon Pool boiled with it!

The Demon Lord of the Dark Dragon, who was originally sitting next to Longtan, suddenly got up, a trace of surprise flashed in his eyes, and he couldn't help but fly over Longtan again.

He could feel the change in Longtan, however, he couldn't detect the source of this change at all.

At the same time, under the dragon pool, a roaring sound sounded again in Wu Chi's soul.

"Damn...... How could it be you, haven't you been interrupted, and even the sword soul has been scattered?"

This sentence made Wu Chi's soul shake again, and more importantly, the meaning contained in it!

This dark dragon ...... It's still alive?!!

"You're this dark dragon?"

Wu Chi struggled to ask.

"Huh?"

Hearing Wu Chi's words, the Dark Dragon was slightly stunned, and then laughed, "I see, haha, I see! I'll just say, its sword soul has long been scattered, how can it still appear here, it turns out that it has already recognized a little guy as the master! However, the little guy is a little weak...... Hmph, without the sword soul, what can you do with the ancestor?"

"Junior Wu Chi, meet the senior of the Dark Dragon!" After confirming the identity of the other party, Wu Chi immediately did not dare to hesitate and immediately saluted.

Chengying Sword may not be afraid of this dark dragon, but he is still far behind.

"Little one, take your sword away before you speak. ”

The voice of the dark dragon sounded again, and it seemed that even the surrounding dragon power had dispersed a lot.

Wu Chi subconsciously wanted to put away the sword, but at the moment when he wanted to draw the sword, the sword soul couldn't help but tremble suddenly, which suddenly woke Wu Chi up.

Now the Chengying Sword is pierced in the skull of the Shadow Dragon, so it will alarm this Shadow Dragon to talk to him, but Wu Chi remembers very clearly that the reason why he was able to pierce this sword before was not by his own ability, but by virtue of the sword intent that burst out of the Chengying Sword.

I'm afraid that the strength of the Chengying Sword itself is not much left, if he forcibly pulls out the sword, who is sure that he can still stab the second sword?

Once he loses the protection of the sword intent of the Chengying Sword, he is afraid that he will be crushed by this terrifying dragon power in an instant.

But if this dark dragon has the slightest malice towards himself, who will he cry with when the time comes?

As soon as he thought of this, a layer of cold sweat suddenly oozed from Wu Chi's vest, and then he spoke, "Senior Dark Dragon, it is not under my control now, and I can't pull it out at all." ”

"Fart, the sword soul has been dispersed, and now there is at most a remnant of the sword soul left, how can it disobey your will?"

It's a pity that Wu Chi, who reacted after reacting, was unmoved, "I don't know, Stygian Senior, maybe its sword soul is actually not dispersed?"

This is talking nonsense with your eyes open.

Immediately, the dark dragon was not light, but he also understood that this kid was cunning and tight, and he was not fooled at all.

"Boy, take away your sword, the Ancestor can make an ancient covenant with you, and he will not hurt you in the slightest, and can even give you more benefits, how about it?"

The Ancient Covenant!

Wu Chi has never heard of these four words at all, but just by his name, he can understand that this is definitely not a joke, but I am afraid that it is much more important than the natal oath.

The most important thing is that this sentence seems to be enough to explain the identity of this dark dragon.

This dark dragon is really an ancient existence?

"By the way, you don't know the Ancient Covenant, believe the Ancestor, the Ancestor is the Ancient Dark Dragon, as long as you take this damn sword away, the Ancestor can meet all your requirements!" the Dark Dragon spoke again.

As soon as his mind turned, Wu Chi suddenly sneered, "Senior Immortal Dragon, aren't you deceiving me into ignorance? Since this sword can fall into my hands, I have naturally obtained the inheritance of the primeval power, how can I not know the primeval covenant?"

While speaking, Wu Chi deliberately released a trace of primeval power!

The power of the primeval is true, but this is definitely still talking nonsense with his eyes open.

Of course, for the dark dragon, he couldn't tell the truth of what he said, and for a while, he couldn't help but be silent again.

It's not that he doesn't want to pretend to be profound, but now he doesn't have the patience to continue to drag it out, the Chengying Sword pierces into his bones, devouring his dragon soul every moment, this is the most terrifying thing for him, how dare he drag it down with Wu Chi?

"Let's be honest, how on earth are you willing to take this sword away?"

"The predecessor is the Ancient Dark Dragon, and he obviously knows this sword...... Why don't you tell me first, what is its origin?" raised his eyelids slightly, and Wu Chi asked quietly.

When he saw Dao Ancestor in the Heavenly Dao Temple before, Wu Chi had heard Dao Ancestor mention this sword, it seemed that Dao Ancestor knew it, but Dao Ancestor didn't mention it at all! Now this Ancient Dark Dragon actually recognized the Chengying Sword as well, how could this make Wu Chi not curious!

"You don't know...... You really don't know!" the Ancient Dark Dragon said in a deep voice, "This sword is a fierce sword, the Ancient Sword Lord fell in the First Battle, and the sword soul was also scattered...... Now it can only be regarded as an ordinary primeval immortal sword, if you believe in the ancestor, you should quickly throw this sword away! In the treasure house of the Dark Dragon Yuan, there is no shortage of primeval magic swords, the ancestor can call the shots, you can choose. ”

"Senior, it seems that he hasn't answered my question yet. ”

Wu Chi was unmoved and asked in a deep voice.

Slightly sluggish, the ancient dragon was a little angry, but now it was controlled by the Chengying Sword, and there was no way to take Wu Chi at all, so he had to reply, "This sword is called Chengying, it was held by the Chengying Sword Ancestor in the past, and it was the first fierce sword in the primeval world, and the ancient battle, the power that fell under this sword is unknown! It's just that with the fall of the Chengying Sword Ancestor, this sword was also hit hard, and even the sword soul was scattered, and I don't know where it was lost......"

"Roar!"

As he spoke, the Ancient Dragon let out another roar, "Get rid of this damn sword!"

The first fierce sword of the primeval world!

For a moment, Wu Chi's heart couldn't help but tremble fiercely, even if he had guessed the extraordinaryness of the Chengying Sword a long time ago, he didn't expect that it would have such a fierce reputation.

Unconsciously, Wu Chi remembered again that when he had just obtained the inheritance of the Shadow Divine Sword in the past, he had dreamed back to Taigu and saw a vague figure, tearing the sky with a sword and slashing the true dragon and the nine heavens, killing the kun and eating meat, above the common people!

The sword collapses in the sky, and the sword cracks the ground!

With a sword, he forcibly killed a piece of Lang Lang for the human race, this is the ancient powerhouse, like a god!

I used to think that it was just a small world, but now that I think about it, I am afraid that this is not an illusion at all, but a real existence.

It's just that now the Chengying Sword has been hit hard, and the sword soul has been scattered, which is indeed consistent with the judgment of the Lord of the Sword Palace in the past.

No matter how terrifying the Chengying Sword was in the past, it is no longer as powerful as it is.

In an instant, a flash of aura flashed in Wu Chi's mind, and he slowly spoke, "Senior Immortal Dragon, now that the Shadow Inheritance Sword is devouring your dragon soul, it is recovering the sword soul, right?"

"Fart!" Sensing the chill in Wu Chi's words, the Ancient Immortal Dragon suddenly scolded, "Do you understand what the primeval No. 1 fierce sword is?
