My martial arts will hang up.

And when his consciousness was about to fall into a deep sleep, he faintly heard the sound of an owl.

"Have you fused blood crystals before? That would be even better..."

……

"call!"

After sleeping for an unknown amount of time, Chen Fan opened his eyes again.

He only felt that his blood was agitated, and a violent emotion rose from his heart, giving him an urge to destroy everything!

The "Ten Thousand Miles No Trace Talisman" was lying quietly in front of Chen Fan. Chen Fan reached out to hold the "Ten Thousand Miles No Trace Talisman" in his hand, but he didn't intend to crush the Ten Thousand Miles No Trace Talisman!

At this time, he naturally gave up running away and left here. With the strength and means of this owl, it is absolutely impossible for him to escape here!

And the owl also said that this tower is blocked by space, Chen Fan doesn't think it is necessary to lie to himself with such an existence.

He took a deep breath.

My mind was spinning fast.

With the strength of this owl, killing himself is naturally extremely easy, and it is not for killing himself that he spent so much effort.

"What's wrong with my body?"

He raised his hands, his skin was translucent and red, and his body was slightly bigger than before.

He could clearly feel the strange power in his body, which was pure physical power.

At the same time, his true energy was running, and he could clearly feel that there was an extra stone-like existence in the dantian of the lower abdomen!

It is the blood species that the owl mentioned, and it is also the token for entering this "research tower".

And in front of him, is a pile of blood spar!

Even he was surprised:

"These are all blood crystals?!"

There are hundreds of spars in this pile, and each of them is at least a high-level blood crystal above the seventh level!

As soon as the owl's wings were raised, a jade document floated in front of Chen Fan, "You wake up, quickly practice this blood fusion art, and start absorbing blood crystals."

Chen Fan was stunned: "Blood Melting Art, absorbing blood crystals?"

He rubbed Chaos's head, frowned and looked at the owl apprehensively, "I don't know, senior, can I help you out?"

The owl said: "If you want to leave the research tower, you have to keep going up and climb out of the tower."

Chen Fan's eyes lit up, and then he looked up at the tall stairs next to him, "What does this have to do with my absorption of blood crystals?"

Owl said:

"There are a lot of 'blood demons' locked in the research tower. The weakest is weaker than you, and the strongest is equivalent to your dwarves' long-lived warriors. If you want to leave, there are two ways. One is to defeat them by strength. The blood demon blocking the way, the other is to get the approval of the blood demon..."

"With your current strength, you can climb to the top three at most. If you want to defeat all the blood demons and break out of the tower, I'm afraid 1000 years will not be enough!"

"And if you keep absorbing blood crystals, when enough blood crystals are incorporated into your body, you can also be identified as the same kind by the 'blood demons', and they will not attack you if they agree with you..."

What the owl said made Chen Fan understand.

It's just that he took a deep breath and asked, "Eternal Life... what is that?"

The owl said a little strangely: "The immortal state is the cultivation of immortality. You dwarves, don't you have the realm of transformation, fish jump and immortality? You don't even know this, are you still a dwarf?"

I don't know how many years Owl has been in this research tower, how many trials he has seen, and his understanding of human fighters is much higher than that of Chen Fan!

Chen Fan's eyes widened: "Immortal Realm, surpassing the tenth level, originally called the Immortal Realm!"

He has heard that there are strong men who surpass the tenth level in Daqian, but this is the first time he has heard that this level is called the longevity level!

This was something neither the master nor Mao Wangchen had ever told him!

And he never expected that in a tower of the Gorefiend Secret Realm, there would be a powerful creature that surpassed the tenth level!

Chen Fan even heard the casual feeling from the owl's tone. He noticed that the owl used the verb "close".

The secret realm named after the Gorefiend, it turns out that the Goregore is just a care creature locked in the trial tower!

Chen Fan narrowed his eyes, raised his head suddenly, and couldn't help saying:

"The so-called blood demon, is it just a martial artist who absorbs too many blood crystals, is dominated by evil spirits, and loses his sanity?"

The owl's head turns back and forth:

"Some blood demons are indeed dwarf warriors who were swallowed by blood demons... There are also special blood demons. Your dwarves' bloodlines are too weak. The blood species allows you to practice blood fusion, but if you don't meet the requirements, you may still be killed by blood demons. Crystal evil influence!"

"Only by cultivating the "Blood Fusion Technique" to a higher level, can you absorb enough blood crystals to withstand the impact of a higher blood demon without collapsing..."

"The purpose of the research tower is to change the bloodline research. If you can absorb the five hundred blood crystals within the given time, your bloodline will be considered to have completed the initial transformation, and you will be able to suppress or even dominate the blood demon..."

"When you reach the top of the tower, you can get a chance to completely change your bloodline...and leave the research tower, and you can slowly rely on absorbing blood crystals to complete the transformation in the future..."

Practicing the Blood Fusion Art, the purpose of absorbing blood crystals is to smelt a special "bloodline"!

Chen Fan buzzed his head, swallowed, and couldn't help but say:

"How far should I practice the blood fusion technique, and how many blood crystals can I absorb before I can get the approval of the blood demon and leave the trial tower?"

Owl Wings Club:

"Practice the third level of blood fusion within three years, absorb all the five hundred blood crystals, and you will be able to meet the most basic conditions, and you can...leave this trial tower."

"Within three years? Absorb five hundred blood crystals?!"

Chen Fan swallowed again.

After absorbing dozens of blood crystals, he has already reached his limit and is about to collapse!

He looked at the jade document in his hand, and the key to absorbing five hundred blood crystals should be the "Blood Fusion Technique"!

He picked up the jade ultimatum, and his true energy entered it.

And the jade ultimatum directly turned into a streamer and penetrated into his forehead!

At the same time, a series of messages appeared in Chen Fan's mind.

There is an extra practice method of "Blood Fusion Technique" in his mind!

Only the first weight.

As the first method of "Blood Fusion" appeared in his mind, he also automatically unlocked this secret method!

He closed his eyes for a long time before finally opening them. A gleam of light flashed in his eyes, "Blood fusion is really a magical secret technique..."

[229.Chapter 23 blood fusion, research]

In the realm of a master, the way to improve one's cultivation is to absorb the power of heaven and earth to strengthen one's body...

But as a human, unless there are some special constitutions, the blood and genes of ordinary people determine the upper limit of physical strength!

Even if it reaches the Nine Levels of Perfection, it cannot be compared with monsters and creatures of other special races!

This is the inherent deficiency of human beings, the upper limit of race!

The so-called blood fusion technique is a secret technique that fuses the blood in the blood crystal into one's own. By changing the blood, one can increase the upper limit of one's physical fitness!

"Fantastic, exquisite! There is such a secret technique in the world!"

Chen Fan was speechless. His knowledge is not small, and he has seen the secret methods in the Yuanshang Secret Realm, such as the nine-star Yuandan, which is a very powerful secret method for increasing the true essence, but compared with the "Blood Fusion Art", it is not at all. There is no comparison.

"And what kind of creature is that blood beast? The blood crystals contained in its body seem to contain the blood of a special race. The key to practicing blood fusion is to absorb blood crystals and change its blood..."

Chen Fan picked up a blood crystal, ran the "Blood Fusion Technique" naturally, and soon completely absorbed a blood crystal!

After absorbing the blood crystals, Chen Fan closed his eyes tightly, opened them after a long time, and his eyes shone brightly on his pale face!

Although you can still feel the impact of the evil spirit, using the "Blood Fusion Technique" is much less burdensome than directly absorbing the evil spirit!

And he had clearly reached the limit of the number of blood crystal fusions, but he was able to continue at this time!

He took a short rest before continuing to absorb the next blood crystal.

After absorbing ten blood crystals all the time, Chen Fan sprayed blood, unable to withstand the impact of evil spirit anymore, and stopped.

"Based on the progress I have just made in unlocking "Blood Fusion", I can reach the current level for the time being!"

His own limit at this time is to absorb so many blood crystals.

If you want to absorb more, you need to upgrade the "Blood Fusion Technique"!

"If it were an ordinary person, it would probably take countless hours to get started with this kind of secret technique, let alone practice to a higher level, but for me, no matter how difficult the kung fu is, I can directly unlock it and start hanging up. Since there are people in history who can If you leave, I can do the same!"

Of course, if Chen Fan hangs up, there is a vacant slot!

Although he doesn't have it now, the fourth part of his "Nine Layers of Thunder Saber" will be completed soon, so it won't take much time!

"I unlocked the "Blood Fusion Technique", and I was able to hang up successfully in about three months for the first stage. I don't know how long it will be for the second stage...Three years for the third stage. If there is no efficiency improvement, it may be a bit hanging!"

For secret methods like this, the difficulty increase is very large.

The difficulty of the first level and the second level may be ten or twenty times different!

Seeing that Chen Fan can complete the first stage very quickly, but the second stage may take two years, and the third stage may take 20 years!

He looked at the owl again: "I don't know, senior, is there anything in this research tower that can improve my progress in comprehending "Blood Fusion"!"

"All the books here are my research records, you can watch them at will, and besides..."

The owl flapped its wings and pointed to the top:

"All the blood demons above are people who absorb blood crystals. They have practiced "Blood Fusion". If you kill them, dissect their corpses, or absorb the blood crystals in their bodies, it should be able to help you improve your "Blood Fusion Technique." The progress of the Art..."

"Of course, it may also make you go crazy faster and become a blood demon..."

The corner of Chen Fan's mouth twitched slightly.

"I remember Senior said that there should be a Gorefiend who is weaker than me...is there?"

The owl nodded: "It should be said that the number of Gorefiends weaker than you is the largest, and they are all in the first few floors, and those stronger than you are in the back few floors!"

Chen Fan's strength is much lower than Yuyue and Changsheng's, but after all, he has reached the stage of transformation, and he is relatively strong in a large population base.

He nodded, and after a little trimming, he began to flip through the records on the bookshelf next to him!

The strange thing is that although Chen Fan doesn't know the words recorded by the owl, he can understand the meaning at a glance.

And his "god" is strong enough, his memory is very strong, and his reading speed is also very fast.

……

Time passed, a few days later.

Chen Fan put down a book in his hand, raised his eyebrows slightly:

"It turns out that the meaning of the existence of the research tower is to continuously improve "Blood Fusion" until it meets the requirements..."

This blood fusion technique itself is only a secret technique in theory, and the existence of this research tower is to continuously practice and improve this secret technique and complete the change of blood vessels.

In the past, I don't know how many tens of thousands of years it took for the "Blood Fusion Technique" to be perfected to the present state.

The records Chen Fan watched started from the most primitive "Blood Fusion" research, and he could see many detours in it. Compared with the "Blood Fusion" in his brain at this time, it can be confirmed. Deeper understanding.

"I've unlocked the first level of "Blood Fusion Technique" right now, but there's no need to watch the higher-level records in depth, and I can start practicing!"

His eyes flashed, and then he immediately walked towards the stairs, stepped up, and headed to the second floor.

After stepping on the second floor, a strong bloody smell spread to Chen Fan's nostrils...

Brush brush!

A group of figures rushed towards Chen Fan in an instant!

The tyrannical and murderous intent rushed straight to Chen Fan's face.

Chen Fan reacted extremely quickly, drew his sword out of its sheath, and slashed horizontally with the sword energy, cutting several figures flying in front of him into pieces of corpses.

In the distance, more figures rushed towards Chen Fan.

There are at least a hundred people on this level.

There are people who are red all over and have red eyes!

There are also some beasts similar to the blood beasts from outside!

All the Gorefiends on this level are below the seventh level, so even though there are a lot of them, Chen Fan can still deal with them very easily!
