Mortal blood!

"I hope so." Xiao Bo agreed.

Soon, Fairy Yuchen and Xiao Bo talked about some other things, and then Xiao Bo left.

...

Three days later, huge fairy boats rushed out of Tianyun Fairy City.

Soon they left Tianyun Realm.

Not long after, they sailed into the vast starry river.

Among them, a young man was standing on the bow of a luxurious fairy boat.

He was Lin Fan.

Looking at the vast starry sky, Lin Fan's expression became extremely solemn.

"Friend Lin?"

Fairy Yuchen's voice suddenly sounded from Lin Fan's ears.

"What do you want to see me for, fairy?"

Lin Fan smiled slightly.

Looking at Fairy Yuchen who suddenly appeared, he was inexplicably surprised.

It has been dozens of days since he left Tianyun Fairy City.

But Lin Fan has never seen Fairy Yuchen.

Unexpectedly, Fairy Yuchen appeared beside him today.

"Fellow Daoist Lin, what are you saying? If I'm fine, can't I come to you?" Fairy Yuchen said with a smile.

"Of course!" Lin Fan said with a smile.

"Fellow Daoist Lin, if you really can't find the Fairy Demon Crystal and the Heavenly Demon Fantasy Spirit Grass after entering the Heavenly Demon Realm, you don't have to worry. I'll let the Baicaotang Chamber of Commerce think of a solution for you." Fairy Yuchen said.

"Thank you, Fairy."

Lin Fan thanked him.

Soon, he smiled again: "Fairy, you came to me now, are you not here to tell me these things?"

"Of course not, hundreds of thousands of miles ahead is the famous Demon Ancestor Blood Sea. There, many powerful Demon Ancestors have fallen."

"I came here this time to remind you that the Demon Ancestor Blood Sea is extremely dangerous. No matter what happens, don't leave the fairy boat."

"This... Is there any other explanation?"

"Hehe, I can't explain the reason. However, when you get to the Demon Ancestor Blood Sea, you should understand something."

Fairy Yuchen explained with a smile.

The journey was long, and the two stood on the fairy boat, looking at the starry sky around them, talking about the various customs and customs in the True Immortal Realm, which was quite pleasant.

After a few days, accompanied by a sharp buzzing sound, the extremely powerful protective formations on the fairy boat were instantly opened.

The speed of all the fairy boats also suddenly decreased at this moment.

This made Lin Fan look surprised.

"Fairy, why did the immortal boat suddenly slow down?"

"Fellow Daoist Lin, we have arrived at the Demon Blood Sea. All immortal boats passing through here must slow down. If the speed is too fast and attracts the evil spirits in the Demon Blood Sea, I am afraid we will not be able to escape death."

Fairy Yuchen explained.

Lin Fan looked alert when he heard this.

His mind and clear eyes spread rapidly.

Not long after, he saw an area where a huge red light fog was located dozens of miles ahead.

In the red light fog, extremely terrifying auras kept emanating.

A terrifying and murderous aura kept emerging.

At first, Lin Fan could only see a series of illusory demon phantoms wandering in it.

But as time went on, Lin Fan was shocked to find that the auras emitted from the demon phantoms became stronger and stronger.

There were even a lot of demon phantoms in the realm of immortal saints and even the realm of Daozu.

"This Demon Ancestor Blood Sea is really incredible. Since these powerful demons have fallen, why do their souls always stay in the Demon Ancestor Blood Sea and cannot enter reincarnation?" Lin Fan asked in confusion.

"Fellow Daoist Lin, I know something about this. It is said that there is a curse from the Tianxie Clan in the Demon Ancestor Blood Sea. Therefore, even the souls of the demons at the Dao Ancestor level are imprisoned in this world and cannot leave."

"Tianxie Clan?"

Lin Fan's expression changed slightly.

The short-lived curse in his body is one of the spells of the Tianxie Clan.

Over the years, Lin Fan has been tortured by the short-lived curse and is in agony.

Naturally, he has no good feelings towards the Tianxie Clan, and even has a little fear.

Hearing Fairy Yuchen say that there is a curse from the Tianxie Clan in the Demon Ancestor Blood Sea in front of him, Lin Fan is even more afraid.

Wow!

The fairy boat broke through the red light fog and moved forward slowly.

The soul of the powerful demon cruising nearby also rushed towards the fairy boat at a high speed.

At this moment, they were carrying a powerful and terrifying aura, which frightened Lin Fan.

However, Fairy Yuchen looked normal.

Seeing this, Lin Fan also breathed a sigh of relief.

"The fairy boat of Baicaotang Chamber of Commerce has traveled this road countless times. Every time, it can safely pass through the Demon Ancestor Blood Sea. There shouldn't be any accidents this time, right?" Lin Fan said secretly.

But at this moment, looking at the terrifying demon souls, which were blocked by the formation light curtain on the fairy boat, Lin Fan became more and more puzzled.

"Fairy, there are not many souls of these demon clan masters. Why didn't the masters in the past attack them? Let them live in the Demon Ancestor Blood Sea?" Lin Fan asked in confusion.

"Fellow Daoist Lin, the souls of these demon clan masters have gone through countless years and still exist today. It's not that the masters in the past turned a blind eye to them. It's that they can't be killed at all."

"Why?"

"You will know later, Fellow Daoist Lin."

Fairy Yuchen's expression became extremely strange when she said this.

Seeing this, Lin Fan didn't ask any more questions.

He could only stand quietly on the immortal boat and pay attention to the movements around him.

As the immortal boat continued to move forward, the spirits of the powerful demons who appeared near the immortal boat became more and more numerous and more and more powerful.

Even the spirits of many hot-tempered demons began to attack the immortal boat of Baicaotang.

But no one took action.

After waiting for a long time, Lin Fan was surprised to find that the spirits of the powerful demons who had been violently attacking the protective formation on the immortal boat, for some reason, actually fled in panic.

In just a moment, they flew dozens of miles away.

At this moment, the speed of the immortal boat suddenly increased several times.

"This..."

Lin Fan looked surprised.

His mind was suddenly urged to the extreme.

Not long after, Lin Fan was surprised to find that in the Demon Ancestor's blood sea, there was actually a terrifying golden flame that spread rapidly from the sky and the earth.

The spirits of those powerful demons who were unable to hide were immediately covered by the terrifying golden flame.

Soon, the terrifying destructive force tortured the souls of these demon clan warriors to the point of extinction.

But soon, the souls of these demon clan warriors were restored in the terrifying golden flames.

It was as if they were reborn from the ashes.

"Is this the immortal fire?"

Lin Fan looked at the scene in front of him curiously, and was inexplicably horrified.

Immortal fire!

This was a natural treasure that only the Shifeng clan had.

It is said that when Shifeng fell, his body was burned by a ball of fire, and he was reborn from the ashes.

At this moment, looking at the souls of these demon clan warriors, after experiencing countless tortures, they were restored to their original state. The first thing Lin Fan thought of was the immortal fire.

"Fellow Daoist Lin, the Immortal Divine Fire is the treasure of the First Phoenix Clan. How could it appear here?"

"The golden flames you see are the famous Life and Death Devil Fire."

"This Life and Death Devil Fire is the life-defining magic flame of the Demon Ancestor Luohou. During the ancient True Immortal Realm, during the battle between the five great Dao Ancestors, a strong man severely injured the demon Luohou. He snatched a wisp of the Life and Death Devil Fire of the demon Luohou. Unexpectedly, the last wisp of the Life and Death Devil Fire was used to deal with the demon clan strongmen. This is really a pimple."

When Fairy Yuchen said this, a strange smile appeared at the corner of her mouth.

But when Lin Fan heard this, he immediately showed a solemn look.

"I didn't expect that this Life and Death Devil Fire was actually Luohou's thing."

"No wonder the souls of these demon clan strongmen are reborn in the Life and Death Devil Fire again and again. Alas... However, the pain they endured is not as good as being killed."

Lin Fan sighed.

But he didn't say much.

He had only heard a little about the battle between the five great Dao ancestors. He was not clear about the specific right and wrong.

At present, Lin Fan only wanted to practice well and strive to make himself stronger.

Only in this way could he go to the Nine Heavens to find Lan Lan as soon as possible.

Huh!

The life and death devil fire in the distance was still burning wildly.

The soul of the tortured demon clan strongman struggled out of the life and death devil fire again and fled quickly.

At this moment, without the harassment of the demon clan strongman's soul, the speed of the immortal boat became faster and faster.

After just more than ten days, it was completely in the Demon Ancestor Blood Sea.

This made everyone secretly relieved.

"Although there seems to be no danger in the Demon Ancestor Blood Sea, there are dangers everywhere. If the spirits of those powerful demons destroy the formation on the fairy boat, I am afraid that any powerful person who enters the Demon Blood Sea may die."

"This place is the real dangerous place."

"But who is it that has done such a big thing? They actually imprisoned so many powerful people here with the spells of the Tianxie clan? They are suffering such painful torture all the time?"

Thinking of this, Lin Fan's eyes were more puzzled.

However, Lin Fan did not know much about these things in the ancient true fairy world.

After thinking for a while, seeing that he had no results, Lin Fan was too lazy to think about it.

He simply found a secret room and entered the fairy bottle to meditate and practice.

In a flash, decades passed.

Lin Fan in the fairy bottle, because the fairy pills on hand had been consumed, his realm remained in the late stage of the Daluo Jinxian realm.

However, his aura was much more powerful than before.

At this moment, the three Immortal Devouring Pythons, fed with a large amount of immortal pills by Lin Fan, finally broke through to the initial stage of Daluo Jinxian realm.

As for the Iron-Eating Ants, it was the same as before.

After Lin Fan fed all the Immortal Demon Crystals in his hand to the Iron-Eating Ants, the realm of the group of Iron-Eating Ants did not improve at all.

"It seems that if the Iron-Eating Ants want to continue to improve their realm, they really need a lot of Immortal Demon Crystals."

"However, I have been practicing in seclusion in the Immortal Path Bottle space. Calculating the time, it has been nearly a hundred years since we left Tianyun Immortal City. We should not be far from the Heavenly Demon Realm now, right?"

Lin Fan said this without any hesitation.

His figure flashed, and he immediately left the Immortal Path Bottle space and appeared directly on the deck of the Immortal Boat.

Not long after, a huge barrier light shield appeared in Lin Fan's sight.
