Taking out the pill and taking it, replenishing the consumed essence and blood, Chu Duan held the no-return sword in his left hand, stretched out his right hand, and bent his five fingers to clasp the air, the gesture was like holding the hilt of a sword.

"Come out!" A low shout, the outside world couldn't hear it, Chu Duan's body qi and blood tumbled, there was a thunderous rumbling sound, the sword fetus in the middle dantian trembled suddenly, let out a clear sound, and instantly, it turned into a silver streamer, like a meteor that cut through the sky, and went straight to Chu Duan's meridians to his right hand.

With a buzz, there was a sword roar piercing the sky, and I saw Chu Duan's tiger's mouth, a pure and brilliant silver sword light poured out, with a trace of gold, piercing the air in front of him, and the edge that broke out in an instant made Chu Duan tremble.

The edge flashed and disappeared, and Chu Duan's right hand held a sword weapon, which was similar in appearance to the eight-sided Heavenly Desolate Sword, the blade was pure silver, and the sword spine and blade each had a golden color.

When the sword is held in the hand, there is a feeling of blood connection, which is different from the usual feeling of holding the sword.

The blood connection that usually holds the sword is because the sword has been held for a long time and is used to it, as if it has become a part of the body, the extension of the arm, and because the control of the strength and quantity has been deepened, it has reached the unity of the human sword.

And now the blood connection is the real blood connection, this sword is grown in the body, as if it is like the five internal organs, arms and legs, no longer extended.

This feeling is really a sword in hand, heaven and earth are the only one.

With this sword, he performed a few swordsmanship moves, and it felt completely different from before, and he really did whatever he wanted, Chu Duan believed that if he had fought with the evil before. If you have this sword, you can shorten the time of battle. Slay the Evil Sooner.

Putting away the no-return sword, Chu Duan pointed with his left hand. Gently rubbing the sword body, the cold touch, the feeling of blood connection, made him intoxicated.

Chu Duan was very happy, happy from the bottom of his heart, he didn't know how to describe his joy at this time.

At the same time, Chu Duan was also a little regretful, because although the sword tire was formed, it was far away from becoming a real divine sword. There's still a long way to go.

There are high and low quality swords, lower grade, middle grade, upper grade, best grade, and then Wang Pin Huang Pin and so on, within each grade, there is also a difference between high and low.

According to the grade of the sword, the sword tire that has just been formed at this time. It is equivalent to the pinnacle sword weapon of the lower grade, of course, because it is made of all kinds of precious materials with the sword technique of the god desolate species, and it is harder, tougher and sharper than the pinnacle sword weapon of the lower grade. It is comparable to a medium-grade sword.

But this is far from enough, at the very least, this sword must reach the quality of the pinnacle of Wang Pin. It is best to reach the imperial rank so that Chu Duan can apply it to battle. Otherwise, once damaged, it should be repaired. It's also quite cumbersome.

After playing with a few swords, with a hint of regret, Chu Duan put away the sword, only to see that it turned into a silver light, submerged into Chu Duan's palm, returned to the middle dantian, and turned into a small sword.

To improve the quality of the sword, you also need the secret method of slaughtering the gods.

Taking out the No Return Sword, Chu Duan glanced at the pitted ground and walls that had been destroyed by the fierce battle, smiled, took down the space ring of the underworld, and walked towards the two genius corpses of the Hades Clan before.

The secret method of the slaughtering god weapon operated, and two pure gray breaths flew out of their bodies, and they were instantly inhaled by Chu Duan, the sword tire was formed, and the suction power was even stronger, and the two wisps of gray breath were sucked into the sword, and the sword body shook, and the immature sword roar showed that it was very comfortable.

This is like a little life, which makes Chu Duan's heart have an indescribable feeling, a trace of softness.

After some looting, the body was burned, and Chu Duan continued to go deep into the stone tomb.

This stone tomb is actually quite large, located in the underground of the blood-colored wasteland, and the passage is crooked, so the battle between Chu Duan and the genius of the Hades God Clan did not affect others, and when Chu Duan left, some people passed by, and when they saw the damaged and pitted ground and the passage wall, their faces were full of horror.

What kind of force can cause such damage, these ordinary geniuses can't imagine.

......

After years of exploration, the tombs in the stone tombs were basically developed, and Chu Duan could only go all the way, bending along the passage to find the unexplored tombs.

Gradually deepening, Chu Duan stopped, in front of him, there was a tomb, except for the tomb, there was no fork, it seemed to be the end.

"Could it be that I have already reached the center of the stone tomb?" Chu Duan couldn't help but have a thought, and it flashed.

The tomb in front of him had not been opened, and a force was entrenched, and when he got closer, he felt a great pressure.

Looking at the door of the tomb, Chu Duan had an illusion, it seemed that the tomb had existed for a long, long time, and it had existed since the beginning of the opening of the earth, and it would have existed since the beginning of the primeval realm, and it would be eternal and not decay.

An inextinguishable taste.

This feeling is unprecedented, which makes Chu Duan dignified, and he is also very interested in exploring.

Taking a deep breath, he took a step forward, and strode forward, a trace of edge floated in the air, and countless sword qi swirled, cutting on Chu Duan's body protection sword gang, the body protection sword gang was as fragile as tofu, and it was cut in an instant, but fortunately, the quality of the treasure clothes reached the peak of the imperial product, and the protective power was amazing, so as to block the cutting of the ubiquitous free sword qi.

The closer he got to that tomb, the stronger the sword qi in the air became, and in order to reduce the burden on the treasure clothes, Chu Duan stimulated the body protection sword gang, and the sword yuan operated, strengthening the strength of the body protection sword gang.

If you are a weaker person, you will be afraid that it will be difficult to bear it when you walk here, and it is even impossible to go to the tomb.

This sword qi had been cut and had not dissipated, but the strength had weakened little by little until it dissipated.

"Could this be the tomb of my Terran ancestors?" walked to the stone gate of the tomb and stood still, Chu Duan felt the immortal sword qi floating in the air, and thought secretly.

This stone tomb is buried with human swordsmen, and there are also ancestors of various races, so it attracts all races to enter here, if it is only to bury human swordsmen, people of other races are not so interested.

Being able to meet the tomb of the ancestors of the human race, Chu Duan was naturally very happy.

After observing, Chu Duan soon found that this tomb was different from the tombs he had encountered before, and there was no ban on the stone door of the tomb.

If there is no ban, doesn't that mean that it is easy to open the stone door of the tomb?

Maybe this is the central area of the stone tomb, and the pressure is very high, and the general strength cannot come here, but Chu Duan believes that the strength of the evil spirit will definitely be able to come, and among the various races, there are also powerful geniuses, who may have already been here, but they can't open the stone door of the tomb.

So, what is the mystery of the stone door of the tomb?

Chu Duan immediately studied it, and the power of divine thoughts was released, covering the stone door of the tomb, and he felt it carefully.

The moment the power of his divine thought touched the stone gate, he immediately felt a terrifying edge, and Chu Duan immediately knew that it was a sword intent, a sword intent, left on the stone gate.

The edge of this sword intent is amazing, but strictly speaking, it is definitely not as good as Chu Duan, that is, it has not been tempered to the level of the nine-turn limit, but there should be a tempering to the eighth-turn level.

Controlling a sword intent to shoot towards the stone gate, suddenly, colliding with the remaining sword intent on the stone gate, Chu Duan's sword intent was defeated after fighting against the three breaths.

"Attribute Sword Intent ......"

The attribute sword intent is much stronger than the ordinary sword intent, and the two are completely two levels, just like the gap between the mystery and the rules.

Chu Duan released a sword intent again, colliding with the remaining sword intent on the stone gate, only to be defeated again after three breaths, but Chu Duan's divine thought power has been following, carefully studying the remaining attribute sword intent on the stone gate.

"It's a feeling...... Passed down through the ages, incorruptible and indestructible......" After careful study, the sword intent collision was released again, and Chu Duan could feel that the remaining attribute sword intent on the stone gate seemed to have weakened a little.

As he studied, he thought back to the books he had read, and there were various descriptions and records of attribute sword intent.

"Could it be...... Immortal Sword Intent?" With a flash of inspiration, Chu Duan exclaimed in surprise.

Immortal sword intent, is among the many attribute sword intent, a very high-end one, comprehension is extremely difficult, just like the immortal sword intent of the general level of attribute sword intent, as well as the destruction of sword intent, etc., according to the theory, if you want to comprehend the immortal sword intent, in addition to specific conditions, you also need a premise, the refining of sword intent, must reach the eighth turn.

There is a direct and close relationship between the level of sword intent refining and the level of comprehension attribute sword intent later.

The more high-end attribute sword intent is, the more high-level ordinary sword intent is needed as a foundation to bear.

After continuing to study for a while, Chu Duan became more and more sure that the sword intent remaining on the stone door of this tomb was the immortal sword intent, and he had to contact it personally before he could make a judgment.

"If I stay here and comprehend, I wonder if I can comprehend the Immortal Sword Intent?" A voice came out from the bottom of my heart, like a seed sprouting, growing irrepressibly.

Chu Duan's original plan was to come out for nine months, and after calculating the time, it had only been more than a month, and there were still more than seven months left, so he planned to stay here and carefully comprehend it, to see if he could capture a trace of opportunity and comprehend the immortal sword intent.

As the most high-end of all the attribute sword intent recorded now, Chu Duan didn't dare to expect to be able to comprehend it in just over seven months, you must know that Lu Dao, how many peerless genius swordsmen, throughout their lives, did not comprehend the attribute sword intent, even if they could, it would take a combination of various conditions and take a few years or even longer.

Before this, Chu Duan had not comprehended any attribute sword intent, nor did he have any environment, and now it has only started, and in just over seven months, it is extremely difficult.

Chu Duan is a person who likes challenges, strong, difficult, and all in his challenge ranks.

Even if he can't comprehend the immortal sword intent in more than seven months, I believe that he will be able to leave a trace and a mark on himself. (To be continued......)
