Chapter 3707: Upper Sword Sect Demon Sword

You's qualifications amazed all the elders of Shangjian Sect at that time, and You was positioned as the next leader of Shangjian Sect at a young age.

Even in the eyes of many Shangjian Sect masters at that time, You might lead Shangjian Sect, which was already at its peak, to a new level.

But no one thought that You actually betrayed. He almost swept Shangjian Sect with his own strength, killing most of the masters in Shangjian Sect, and finally made Shangjian Sect completely decline and finally sink into the long river of history.

No one knows the reason for You's betrayal, and after leaving Shangjian Sect, the news of You also disappeared completely.

Although in Jian Ni's heart, You must still be alive, so when Jian Ni was about to die, he also told Chu Fengmian about You.

Now it seems that this You should have entered the Nine Nether World directly after judging Shangjian Sect, occupied the Nine Nether Sea, and was called the Emperor of You by people.

There is not much connection between the Emperor You of the Nine Netherworld and a disciple of the Upper Sword Sect.

So few people know the true identity of the Emperor You.

Even the four major inheritance forces of the Nine Netherworld only know that the Emperor You is from the Nine Regions, but they have no idea about his true identity.

If Chu Fengmian had not seen the swordsmanship of the Upper Sword Sect from the Emperor You, he would not have been able to connect the Emperor You with the Emperor You of the Upper Sword Sect.

"What is this?"

Just as Chu Fengmian was flipping through the memories of the Emperor You from the memory of the Sword Emperor's crown, the Emperor You suddenly made another move, and a spiritual sword suddenly came out of the palm of the Emperor You's hand.

At the moment when this spiritual sword came out of the sheath, a strong murderous intent burst out, and this murderous intent almost dyed the world into a blood red.

"Demon Sword!"

The spirit sword in the hands of the Ghost Emperor is a demon sword. It is unknown how many lives have been sacrificed to condense the killing intent in it to such a terrifying degree, turning it into a demon sword.

Even though it is still inferior to the Blood-Slaying Demon Sword, the demon sword in the hands of the Ghost Emperor has more than 30% of the killing intent of the Blood-Slaying Demon Sword.

This is already a very astonishing number.

The Blood-Slaying Demon Sword was once the weapon of the master. It followed these masters and experienced countless eras. It killed trillions of lives, which made the killing intent of the Blood-Slaying Demon Sword reach such a terrifying degree.

However, the demon sword in the hands of the Ghost Emperor is not the weapon of the master, and it has not even crossed the era.

Chu Fengmian did not feel any primordial power from the demon sword in the hands of the Ghost Emperor, which means that this demon sword is not a weapon inherited from the previous era, but a demon sword forged and refined in this era.

In just one era, this magic sword has such a terrifying murderous intent. I am afraid that this You Emperor has slaughtered hundreds of millions of lives, destroyed countless small worlds, and even killed countless immortal emperors, before he sacrificed such a magic sword.

"This magic sword! Is this the reason why the You Emperor destroyed the Shangjian Sect?"

From this magic sword, Chu Fengmian still felt the swordsmanship of the Shangjian Sect. This magic sword sacrificed the flesh and blood of countless Shangjian Sect masters during the sacrifice, which made this magic sword stained with the breath of the Shangjian Sect.

"This is the sword body that the You Emperor prepared for the core of the Youhai! The reason why the You Emperor betrayed the Shangjian Sect is probably to condense this magic sword!"

This You Emperor actually wanted to refine a dominant weapon that could rival the Blood-Slaying Demon Sword. The magic sword in his hand is actually just a semi-finished product.

Although the power of this semi-finished magic sword has surpassed many extreme immortal weapons, and in the hands of the Ghost Emperor, it can exert an extremely powerful force, but it lacks a power core.

A power core similar to the blood pool in the Blood-Slaying Demon Sword.

The Ghost Sea Core was originally prepared by the Ghost Emperor for his magic sword, but the last time the Ghost Emperor wanted to integrate the Ghost Sea Core into the magic sword, something unexpected happened, which eventually caused the Ghost Sea Core to break and turn into countless fragments.

"If the Ghost Emperor really integrates the magic sword and the Ghost Sea Core into a supreme immortal weapon, I'm afraid no one in this era will be his opponent!"

The era where Chu Fengmian is now is at its peak. The power of the laws of heaven and earth and the power of heaven are extremely powerful, so any dominant strongman cannot take action.

An existence as powerful as the Void God can only hide and sleep.

Once the Dark Emperor completely condenses the magic sword, his strength will be enough to rival the master. At that time, in this era, the power of the Dark Emperor will be invincible and no one can stop him.

No wonder this time, the strong men from all sides joined forces to fight for the Dark Sea core fragment.

Even if the Dark Sea core fragment is useless to them, they can't do anything to let the Dark Sea core fragment fall into the hands of the Dark Emperor.

Once the Dark Emperor truly condenses the magic sword, none of them will have a good ending.

"Not good, this Youdi is going to use a killing move!"

Chu Fengmian looked at Youdi's face, which was already extremely angry. He also knew that this Youdi was really going to use a killing move. Once he used a killing move, a ninth-level immortal emperor, or a ninth-level immortal emperor in the realm of transformation, would use all his strength, and the entire forbidden sea area would be affected.

"Go!"

In an instant, Chu Fengmian's escape light flew out of the forbidden sea area at a very fast speed. Gu Yuan also sensed the danger. Suddenly, a jade talisman appeared in his palm. This jade talisman contained a trace of nothingness.

Under the cover of this nothingness, Gu Yuan's escape light was also extremely fast. In an instant, he left the forbidden sea area.

Just when Chu Fengmian had just left the forbidden sea area, behind him, an extremely terrifying explosion broke out in the forbidden sea area, and the violent sword intent swept everything.

Even Chu Fengmian's spiritual consciousness was unable to detect the situation. His spiritual consciousness was destroyed by the sword intent as soon as it approached.

"The strength of this You Emperor is indeed too terrifying. Is this the ninth-level immortal emperor in the realm of Dao transformation?"

Although Chu Fengmian had heard of the three levels of the ninth-level immortal emperor and the huge gap between them, he had never seen it with his own eyes.

This time, seeing You Emperor take action with his own eyes, Chu Fengmian realized that the gap between each level of the ninth-level immortal emperor was even greater than the rumors.
