Chu Fengmian's eyes were closed. In this sword crystal, the many mysteries of the Zhenyan Immortal Emperor's sword technique were gradually understood by Chu Fengmian and integrated into the ancient sword art books.

This sword crystal contains the sword art of Zhenyan Immortal Emperor. With Chu Fengmian's understanding of the sword art, it is easy to comprehend it, and it only takes a few breaths.

Among the ancient sword books, a page of brand new sword techniques condensed, and the sword techniques of Zhenyan Immortal Emperor were perfectly integrated into the ancient sword books by Chu Fengmian.

The integration of this sword technique has added a little more to the power of ancient sword arts. Although it was just a small fluctuation, it was still enough to surprise Chu Fengmian.

Chu Fengmian's current ancient swordsmanship books have been integrated into thousands of swordsmanship. The swordsmanship of countless immortal emperors and heavenly masters have long been integrated into the ancient swordsmanship books by Chu Fengmian.

The power of ancient kendo books has reached a critical point. Now that he has integrated many sword techniques, he cannot make the power of ancient kendo books go further.

However, the integration of the Zhenyan Immortal Emperor's sword technique has caused the power of ancient swordsmanship to undergo a little change.

Chu Fengmian was surprised, and he also saw it.

The sword skills of the Zhenyan Immortal Emperor alone are not enough to change the ancient books of swordsmanship.

After all, there are hundreds or thousands of sword techniques that have been integrated into the ancient swordsmanship books and the Heavenly Venerable level.

Many of the sects inherited sword techniques he obtained in the Heavenly Sword Leader actually belong to the Immortal Emperor sword techniques.

The Zhenyan Immortal Emperor is just a third-level immortal emperor. His sword skills should not have been improved so significantly. What really changes the sword arts in the Zhenyan Immortal Emperor's sword skills are the crazy sword arts in the Zhenyan Immortal Emperor's sword skills.

When the Zhenyan Immortal Emperor mastered the Blood-Slaying Demon Sword and became the Blood-Slaying Demon, his strength soared. Even the seventh-level Immortal Emperor was no match for him. In the midst of these killings, his swordsmanship also under the influence of the Blood-Slaying Demon Sword, he had subtle changes.

This change was also recorded in the sword crystal.

After Chu Fengmian integrated the sword skills of the Zhenyan Immortal Emperor into the ancient sword books, he discovered that the ancient sword books actually changed, and he discovered this.

"Is the sword path of the Blood-Slaying Demon Sword?"

Chu Fengmian once wanted to try to comprehend the sword of the Blood-Slaying Demon Sword, the Blood-Slaying Demon Sword, but a master sword, and the power contained in it is definitely the master power.

In this era, sword cultivators cannot achieve the master. The Heavenly Sword God Emperor, the First Sword Emperor, and the Lord of Sword Dao were all stuck at the last step.

Therefore, in this era, there is no such existence as the dominant sword, but the power in the Blood-Slaying Demon Sword is indeed the power of the dominant one.

The sword arts in the Blood-Slaying Demon Sword are also the master sword arts. If you can comprehend it, it will be enough to make Chu Fengmian's ancient sword arts change like earth-shaking.

However, no matter how Chu Fengmian tried, he could not comprehend the sword in it from the Blood-Slaying Demon Sword. The power of the Blood-Slaying Demon Sword was far beyond Chu Fengmian.

Chu Fengmian couldn't even deal with a wisp of murderous intent, let alone the sword art of the Blood-Slaying Demon Sword.

Unexpectedly, the Zhenyan Immortal Emperor had done this. His slight understanding should have been realized when he was dying. He had not yet condensed into swordsmanship, but had slightly integrated into his own swordsmanship and remained in the sword crystal.

But this also brought great gains to Chu Fengmian.

"If you can take this opportunity to comprehend the sword path of the Blood-Slaying Demon Sword, or even integrate it into the ancient sword path books..."

Chu Fengmian's eyes flashed. If he could really do this, then his strength and his ancient swordsmanship books would undergo earth-shaking changes. This transformation was something that Chu Fengmian could not match any swordsmanship that he had incorporated into the ancient swordsmanship books before.

Even the secret technique of the Heavenly Sword and the integration of the first sword technique cannot be compared with the sword art of this Blood-Slaying Demon Sword.

"Since you can discover the sword crystal left by the Truth Emperor, then there should be sword crystal left by other powerful people in this blood pool."

There is no detailed record of how many Blood-Slaying Sword Demons have entered the blood pool, but there are always dozens of them.

They never came out when they entered the blood pool, and the Blood-Slaying Demon Sword appeared outside, which also means that these Blood-Slaying Demons who had entered the blood pool had all fallen.

Although they have fallen, their bones and their sword crystals should still exist.

In this Zhenyan Immortal Emperor's sword crystal, there is actually a trace of sword art in the Blood-Slaying Demon Sword.

If Chu Fengmian could find the sword crystals left by other blood-killing sword demons, he might also comprehend the sword art of the Blood-killing sword, or even incorporate it into the ancient sword art books.

Moreover, even among these sword crystals, there is no sword art with the Blood-Slaying Demon Sword, the former Blood-Slaying Demon is without exception. They are all geniuses of sword art, immortal emperor, and powerful people at the level of the Heavenly Venerable.

The sword art contained in their sword crystal is also of great use to Chu Fengmian. It can be integrated into the ancient sword art books to perfect his ancient sword art books.

The ancient book of swordsmanship is an ancient book that integrates all swordsmanship in the world. For Chu Fengmian, the more swordsmanship, the better.

Thinking of this, Chu Fengmian continued to explore. This ancient space appeared in a circle, and although the surroundings were filled with chaos.

The chaotic energy here is already so strong that it is more intense than anywhere Chu Fengmian has seen. Even in the ancient secret realm, the chaotic energy in the place where his sword path Gou Chen is unable to compare with that here.

Chu Fengmian walked step by step, and soon he also discovered a skeleton. This skeleton, like the skeleton of the Zhenyan Immortal Emperor, had completely lost its power and was extremely corrupt. A little bit of power would cause the skeleton to die.

Chu Fengmian was also cautious and shrouded it with a stream of spiritual power. These bones were the former blood-killing sword demons, and they could be called Chu Fengmian's predecessors.

They fell in this blood pool, and Chu Fengmian couldn't help much, so they could only take good care of their bones.

Among this bone, the same jade bone was located between the ribs, and the dazzling light was flashing. It was the sword crystal. When Chu Fengmian moved his palm, the sword crystal was lifted up by an invisible force and carefully flew into Chu Fengmian's palm.
