Yin Feng is very patient, and has been carefully observing those light filaments that are constantly drifting, in terms of observation, he has an innate advantage.

Suddenly, Yin Feng's eyes flickered, and he saw the clues, and he found that the movement trajectory of those red light filaments was regular, not chaotic like the previous eighteen levels.

"Do you want me to form these filaments into glyphs by myself according to the laws of movement of those light filaments, in other words, the test of the nine levels in the center is...... Deduction!"

Yin Feng, who came to the conclusion, was a little stunned at first, and then laughed dumbly, he didn't know what to say, if the central nine levels tested the ability of deduction, then if there was no accident, wouldn't the next volume of the Immortal Blood Book be given to him again?

The outer nine levels test the combat power, the inner nine levels test the combat power as the supplement, and the affinity is the main one, while the central nine levels test the affinity as the auxiliary and the deduction power as the main one.

Combat power, affinity, deduction power, the three rings are interlocking, layer by layer, if you want to get a flawless immortal bloodline, combat power is the basic requirement, affinity is the main requirement, and deduction power is the fundamental requirement.

Until now, to be honest, Yin Feng has some admiration for the senior who created the Immortal Blood Realm in the first place, this is definitely a person with great wisdom and foresight.

If you have strong combat power, you can protect the immortal blood code well, otherwise you will just get it one second ago, and you will be killed the next second, so what's the use of getting a complete immortal blood codex, it's all floating clouds.

Not to mention that you will always be the strongest, at least you must have the ability to protect yourself in the early stage of growth, and the seedlings will not be damaged, so that you can become a towering tree!

After ensuring that there is enough combat power to protect the fruit, the next test is the affinity with the Undead Bloodcode, that is, the potential of the blood, the higher the potential, the stronger the affinity with the Undead Bloodcode.

Only those with high blood potential can give full play to the power of the Undead Blood Codex, so that the Undead Blood Book can shine like the sun and shine over the wilderness.

The final test is the ability to deduce, that is, understanding, after all, even if you have the strength to guard, the blood potential is also great, but if you can't understand it, you can't understand it, you can't understand the meaning of the scriptures, what's the use, everything is still floating clouds.

After a long time, Yin Feng came back to his senses, he sighed with emotion, and bluntly said that he had grown knowledge, this kind of wisdom and experience can definitely be used for reference and learning, and the selection of the most suitable heir should be screened in such a targeted manner.

If he can also open up a holy place in the future, he can use this model when teaching the essence of his life's work.

It is not unreasonable for the Abi Underground Palace to become the head of the Nine Sects, and it does not choose the best for the inheritance of the holy scriptures, and only chooses the most suitable person.

On the other hand, the inheritance method of the Supreme Sword Code is much rougher, only selecting the best people, not the most suitable people, this inheritance model may have obvious effects at the beginning, but in the long run, it is not conducive to the development of the sect.

This inheritance model also brought the Taiqing Red Sword Sect into a dead end, and directly developed an unwritten rule, the Supreme Sword Book was only eligible to be read by the sect master heir, and it was not until Yin Feng appeared that this unwritten rule was broken.

With a light breath, Yin Feng took away all the emotion on his face, his eyes were repeated and clear, and he began to pay all his attention to the red light in his mind, since the test was deduction, then he had nothing to fear.

Yin Feng was engrossed, and his soul power began to follow the trajectory of those red filaments, and after following it three times, he found that the trajectory inside was divided into two directions: one large and one small.

The minor direction is the composition of the font, and the general direction is the direction of the meaning of the text, after all, if there is no general direction guidance, even if those fonts are composed, they will not be able to arrange a complete scripture.

Although Yin Feng has not yet begun to comprehend the first and middle volumes of the Immortal Blood Canon, he is not unfamiliar with the mysteries, and the first volume of the meridians and the second volume of the acupuncture points in the absurd recipes are the cultivation exercises composed of the mysteries.

It is no exaggeration to say that when he was building the foundation realm, he began to come into contact with the mystical and mysterious Dao Truth.

Therefore, Yin Feng can be said to be very familiar with the characteristics of the mysteries, and he feels that the mysteries are coherent, like a river connecting the upper and lower volumes, so even if he does not comprehend the upper and middle volumes, he can deduce the direction of the mysteries.

However, in order to make the derivation easier, Yin Feng still spent a cup of tea and roughly understood the mystical direction of the upper and middle volumes.

After doing all this, he looked at the red light cluster in his mind again, he was not in a hurry to deduce the laws of the general direction, but was ready to start from the small direction, and first deduce those fonts.

There are tens of thousands of red filaments that make up red light, and even though there are rules to guide them, it is still not easy to connect these filaments together to form a text, and it is a great test of deduction ability.

Yin Feng finally understood why Lou Wanzhong, the palace master of the Abi Underground Palace, was killed at this level, not because his blood potential was not good, but because his deduction ability was not up to par.

Yin Feng had devoured the soul origin of the Earth Dragon and Han Gu successively, and the soul deduction had reached thirty-five thousand times in one breath.

Under such a terrifying deduction power, the movement trajectory of those red filaments was like lice on a bald head, which was clear at a glance, and all of them were connected together by Yin Feng.

Then he directly used his soul power to pull those free red filaments of light to the positions that originally belonged to them according to the trajectory after series connection.

Strange to say, as soon as these red filaments returned to the correct position, they immediately stood still and did not wander around.

After a while, the fonts were quickly presented, and after a while, all the red filaments formed the glyphs.

It's just that the distribution of these words is very chaotic, and the mysteries of the practice revealed on the adjacent two characters are not coherent.

Of course, there are also individual cases where the mysteries of practice between two adjacent characters are coherent, after all, they are randomly distributed, and if they are not even, there are individual words that stand in the right position.

The corners of Yin Feng's mouth rose, and with his deduction power, it was not difficult to straighten out the direction of these mysteries.

His soul power surged, and suddenly the fonts jumped back and forth, and it didn't take long for a mysterious and smooth scripture to be presented immediately.

Like the previous eighteen levels, as the scriptures were revealed, a light gate suddenly appeared in front of Yin Feng.

Looking at the light gate in front of him, Yin Feng showed a satisfied smile, and without thinking much about it, he stepped in directly.

Coming to the second level of the center, Yin Feng found that there was also a long path here, and there was still a red mist at the end of the path.

Without spending much effort, Yin Feng quickly got a ball of red light, and with the foreshadowing of the previous level, he didn't want to directly find the law and deduce it.

As Yin Feng expected, the difficulty of deduction in this level is more difficult than the previous level, it is rare that it is not a star and a half, and Leng Tong can be planted here, and it is not wronged.

It's just that for Yin Feng, it's still not difficult, after all, he has devoured the soul origin of two people before and after, and the skin of the soul villain has a trace of flesh color.

It didn't take long for Yin Feng to directly enter the third level of the center.

Immortal blood outside the borders.

"Oh!"

As the dazzling black spot entered the twenty-first area on the stone tablet, everyone exclaimed in surprise.

At this moment, there are still nearly a hundred light spots on the stone tablet, which means that more than two hundred people have been sent out by the Immortal Blood Realm.

Most of the nearly 100 people represented by the light spots were on the periphery of the Immortal Blood Realm, and only a few thirteen people entered the inner enclosure area, of which twelve were in the first level of the inner enclosure, and only one was in the second level of the inner enclosure.

In fact, this batch of disciples who have entered the immortal blood realm is already very good, you must know that only a few disciples in the previous batches can enter the inner enclosed area, and this 'thirteen' is still a pending number, after all, there are still many people in the outer area, and there are still people who can enter the inner enclosed area.

However, at this moment, everyone's eyes were fixed on the black flickering spot at the top, and their eyes did not blink, as if it was not a spot of light, but the brightest star in heaven and earth.

Whenever there was a movement in the black spot, they exclaimed, all words were pale, and only exclamation could vent the emotions in their hearts, because the speed was too fast, and the speed was a little unreal.

And those who were eliminated by the Immortal Blood Realm mostly looked emotional, thinking that there were such gods in their batch, which was a great fortune for the Abi Underground Palace, but it was their unbelief.

However, being able to enter the immortal blood realm with such a group of people will also have some talking points in the future in the face of future generations.

On the thirty-third floor of the Abi Underground Palace, there were more than a dozen people standing at this moment, led by Lou Wanzhong, and there were two disciples, a man and a woman, standing beside him, who were Leng Tong and the holy woman Tang Yuan.

At this time, Leng Tong's face was extremely ugly, his fists were clenched tightly, and even because he clenched it too tightly, the nails of his middle finger were embedded in the flesh of his palm, and what he was most worried about had now become a reality.

Now that a new disciple has entered the third level of the center, in other words, his position has been shaken, and the corner of his eyes looks at Tang Yuan from time to time, as if he is a little worried, afraid that he will see different emotional fluctuations from Tang Yuan's beautiful eyes.

After all, that disciple's speed of breaking through the level was faster than hers, and his talent was amazing, if Tang Yuan became interested in him because of this, the blow to his cold pupils would definitely be fatal.

Because this disciple is not comparable to the garbage of the righteous outer gate, this is a real terrifying elite, even his cold pupil has to admit the terrifying elite.

"Leng Tong, pay attention to your state of mind, you are also the elite of my Ah Nose Underground Palace, there is no need to be presumptuous, those who achieve great things should be broad-minded. ”

As if seeing Leng Tong's thoughts, Lou Wanzhong reminded softly, and then he continued: "I called you and Yuan'er here today, mainly to let you witness the glory of the Abi Underground Palace and welcome the new elite together, maybe he will be a holy son, with the three of you, my Abi Underground Palace will ignore everything!"

Lou Wanzhong stared at the white stone tablet, his pupils beating with excitement, at this moment, he seemed to have forgotten for a short time that the Ten Thousand Medicine Nest had been ransacked.
