In the following time, the Immortal Demon Emperor disturbed Ye Xuan's mind in various ways, wanting to prevent Ye Xuan from continuing to fuse the way of the sword and the "Law of Time".

In the darkness, the "Law of Death" transformed into all kinds of treasures and monsters to attack, but Ye Xuan always sat still.

Although he didn't have the ability to break the Ultimate Death Domain for the time being, the "Law of Death" had already been unable to hurt Ye Xuan.

Ye Xuan sat in the invisible sword domain, no matter how the Immortal Demon Emperor attacked, his state of mind was always as calm as water, concentrating on exploring the higher form of the fusion of the law of sword and the law of time.

In the past two years or so, more than half of this progress has been completed.

At this pace, it won't be long before we succeed.

The appearance of the Immortal Demon Emperor also confirmed this on the side.

It was precisely because he realized that Ye Xuan was about to master the power to break the Ultimate Death Domain that he was about to attack.

It's just that after his body and the "Law of Death" were fused, with the power of the "Law of Death" alone, he could no longer cause harm to Ye Xuan, and there was no other way than to attack.

Ye Xuan also knew this, so he was not affected at all.

The Invisible Sword Domain and the "Law of Time" opened at the same time, blocking the attack of the "Law of Death" and continuing to meditate and comprehend.

Time passed little by little in the silent darkness.

Ye Xuan was getting closer and closer to success, and the attacks of the Immortal Demon Emperor were getting more and more intensive.

It's just that for a few months, he tried all kinds of methods, but to no avail.

Ye Xuan was also used to his attacks, and even when he heard the roar of a giant beast in the dark, he didn't bother to open his eyes and take a look.

Time flies by in this quiet cultivation.

Ye Xuan used himself as a yardstick, measuring the changes in time.

It has been nearly three years since he entered the Ultimate Dead Realm.

The fusion of the way of the sword and the law of time has gradually reached the most critical moment.

The attack of the Immortal Demon Emperor has also reached the point of madness.

Roar, roar, roar......

Outside the Invisible Sword Domain, there are all kinds of fierce beasts roaring and roaring.

Ye Xuan heard the roars of these fierce beasts, but he didn't open his eyes to look.

Because in the past month, the terrifying beast conjured up by the "Law of Death" has been constantly impacting the Invisible Sword Domain.

Ye Xuan was no longer interested in paying attention to it, so he let those terrifying beasts roar and pounce.

The terrifying beast in the darkness roared and roared and pounced on the Invisible Sword Domain, but as long as it pounced into the Invisible Sword Domain, it would be cut into pieces by the edge of the Sword Domain.

Ye Xuan continued his cultivation in this chaotic environment.

I don't know how long it took.

Suddenly, there was a bang.

The Invisible Sword Domain shattered.

Ye Xuan was suddenly startled, suddenly opened his eyes, swung out a sword light, slashed the attack, and then flew back.

When I looked closely, I saw a black shadow that looked like a heavenly demon and a demon appeared in front of me, and a scarlet gaze shot out of his eyes, as if he wanted to choose someone to devour.

Ye Xuan frowned, feeling a little surprised.

The Immortal Demon Emperor had been harassing him for a whole year, but those demons and fierce beasts conjured up by the "Law of Death" had never broken through the Invisible Sword Domain.

I didn't expect that there would be such a strong one now, and it would break the Invisible Sword Domain with one blow.

The red-eyed demon roared, and pounced on it again to attack, and the power it unleashed was enough to shatter the void and collapse the world.

Ye Xuan was even more surprised, and raised his sword to fight with him.

After the three tricks of the hard battle, Ye Xuan was very shocked in his heart, the strength of this red-eyed demon far exceeded the strength that the God Emperor should have.

It is impossible to stop him with the Invisible Sword Domain alone, and he must fight with all his strength in order to resist.

Since there is no way to avoid this battle.

Ye Xuan simply concentrated on dealing with this battle, and put the experience of the sword dao law he had realized in the past three years into full display to fight against this red-eyed demon.

The two sides fought to the ground, and the void collapsed.

Every time the sword is released, it is a power that destroys the world and destroys the earth.

The two sides fought inextricably, and no side was defeated for three days and three nights.

If it weren't for the Ultimate Death Realm, if it were another world, it would have been blown up by such a fierce battle.

Boom!

Rumble!

The battle lasted three days and three nights, and there was still no intention of ending.

The more Ye Xuan fought, the more frightened he became, he didn't expect this red-eyed demon to be so strong.

I don't know how the Immortal Demon Emperor conjured up such a powerful demon.

In the past year, the Immortal Demon Emperor has released a demon that has harassed him, and none of them are as strong as this.

After thinking about it for a moment, it is speculated that the Undead Demon Emperor is also improving the power of the Ultimate Death Domain.

After all, the Immortal Demon Emperor only fused himself with the "Law of Death" three years ago, and three years is actually a very short time for a transcendent existence.

It didn't take long for the Immortal Demon Emperor to merge with the "Law of Death", and it was normal for him to continuously improve the power of the Ultimate Death Domain in the process.

Ye Xuan originally wanted to fuse the sword path and the "law of time" to improve the form of the law of the sword, so as to break the ultimate death domain.

Now, when encountering such a red-eyed demon, you have to go all out to fight it, and there is no time to continue to comprehend the way of the sword and the law of time.

The battle continued.

Ye Xuan tried all kinds of methods, wanting to defeat this red-eyed demon.

But the strength of this red-eyed demon is beyond imagination, and even if you use all your strength, it will be difficult to defeat it.

After the battle lasted for seven days and seven nights, Ye Xuan felt that things were in trouble.

After seven days of fighting, the strength of the red-eyed demon did not decrease at all, and even became more and more ferocious.

It is not the way to continue to fight like this.

Ye Xuan began to think of other countermeasures, first trying to retreat to avoid this red-eyed demon, but the other party's speed was so fast that even if he controlled the sword light and flew away, he couldn't avoid his pursuit.

When it came to the tenth day, Ye Xuan felt that things were getting more and more tricky.

When Ye Xuan was thinking about countermeasures, the attack naturally weakened, and the battle situation gradually fell into disadvantage.

At this time.

The face of the Immortal Demon Emperor condensed in the darkness, and he let out a rampant laugh: "Humble human, how are you going to fight against me this time......?"

Ye Xuan frowned and glared at the face of the Immortal Demon Emperor, with resentment in his heart, he swung out a sword, splitting his face, and then continued to face the red-eyed demon.

After ten days of fighting, Ye Xuan could basically be sure that the strength of himself and this red-eyed demon was almost the same, and if he fought with all his strength, he might not be able to tell the winner for a few years.

Just like the Qingxiao God Emperor and the Immortal Demon Emperor, they have fought for a lifetime, and they still haven't decided the winner.

If you really play here for years, if not decades, things are bad.

At that time, even if he can break the Ultimate Death Realm and get out, the outside world doesn't know what will become of it.
