Holding the jade slip, inject a trace of mana.

A large piece of information instantly appeared in Xia Yin's soul consciousness sea......

After digesting this information, Xia Yin finally understood why the old man couldn't wait to sell the spirit beast.

And there is a reason why he forced himself to sign a blood contract......

This message reads:

The old man's name is Liu Ye, and his ancestors used to be a huge family of cultivators.

More than a thousand years ago, Liu Changgong, the deacon of the Five Elements Sect, was stuck in the middle stage of foundation building because he could not break through the bottleneck, and he knew that his qualifications were limited, and the middle stage of foundation building was already the end of the road to cultivation.

Liu Changgong was disheartened, resigned from the sect, returned to the secular world, married a wife, had children, and did business to accumulate wealth.

With years of savings and connections in the cultivation world, in a few decades, the Liu family has become prosperous and wealthy, and has become a huge cultivation family affiliated with the Five Elements Sect.

The so-called Xiuzhen family is the descendant of the downhill monk family who are attached to the original sect like Liu Changgong.

In the entire cultivation realm, no matter how big or small the outer disciples and deacons of the sects, they know that their cultivation is hopeless, they will obtain the permission of the sect and return to the secular realm to spread their branches.

These people themselves are monks, and their status in the secular world is naturally very high, and they have the support of the big backer of the sect......

For the major sects, this is also a happy thing.

Because these monks who descend from the mountain all have different spiritual root qualifications, and their bloodlines are much stronger than mortals, and their descendants also have a high chance of inheriting this bloodline and possessing spiritual root qualifications.

There is even a small number of Xiuzhen families, after several generations of bloodline fusion, there will be some demons at the level of earth spirit root and heavenly spirit root!

Once this kind of person appears, he will be recruited by the original sect and become the mainstay......

This is the most reliable way for the major sects to ensure the resources of disciples, which can not only allow those outer disciples who have dedicated decades of good time to the sect to enjoy the wealth of the world, but also solve the problem of recruiting disciples......

After Liu Changgong's death, among his eighth generation of descendants, there was a demon with the best spiritual root, who was recruited by the Five Elements Sect as a baby.

In just three hundred years, this person has cultivated to the realm of the Golden Single's Great Perfection!

And the Liu family, under the shadow of this Jindan monk, has become more and more prosperous.

However, it is an eternal truth that it does not come to the extreme, and it flourishes and declines.

During a trip, the Jindan overhaul discovered a rare thousand-year-old elixir, which had just been picked when he was touched by a Yuanying monk who happened to be passing by.

Without saying a word, the old monster shot directly, beat this Jindan overhaul to the point of destroying all the meridians, and after looting all of his body, he walked away......

This Liu family Jindan overhauled and died soon after returning to the family.

He knew that he was going to die, and the reason why he struggled to come back was to confess one thing.

When he was dying, this Jindan overhaul handed over the spirit beast that had accompanied him for hundreds of years to the family, and after some advice, he dissolved the contract with the spirit beast because of the consequences of violating the contract and dying immediately.

And this Jindan overhaul before his death confessed, is to let the family treat this spirit beast who has saved him in danger many times, if there is a descendant with this beast, you can conclude a contract, if not, but also to find a suitable owner for this beast, must not abandon it, let alone let it die for no reason.

After witnessing a group of descendants of the family swearing a poisonous oath in front of him, Jin Dan overhaul died immediately......

But then, the nightmare began.

This little guy named the Yin Eater Beast's only hobby is to devour Yin Spirits, ghosts, demonic energy, and other things that make ordinary mortals smell and change!

Although the Liu family is big, most of them are secular mortals, how dare they go to those filthy places to get these things!

In desperation, the family could only use a lot of financial resources to collect all kinds of things containing demonic energy and yin aura everywhere to support the little beasts.

In less than a hundred years, the originally prosperous family was eaten alive by this little beast......

Moreover, in the past hundred years, the entire eastern part of the Chaotic Star Domain contains demonic energy and yin aura, and all the things that contain demonic and filthy aura have entered the belly of the little beast, and they can't be bought with money.

In the end, the family could only set their sights on the cultivation realm and buy all kinds of defective magic weapons from the Demon Sect to support the little beasts.

However, in the cultivation realm, even if it is a remnant weapon, it is not something that ordinary mortals can easily buy......

The huge Liu family finally became destitute!

Many of the clansmen could not bear it anymore and fled.

Liu Ye's father, the last generation of the patriarch of the family, managed dozens of clansmen in their last years and an empty mansion compound, and had become destitute.

The only thing that surprised Liu Ye's father was that his son Liu Ye actually had the qualification of a medium-grade spiritual root......

However, the Liu family is no longer the immortal cultivator family of the past, and it has also broken off contact with the Five Elements Sect, and the family qualification has been removed, and if you want Liu Ye to worship the Five Elements Sect, you can't enter.

In desperation, Liu Ye's father could only let his son practice some low-level exercises passed down from his family, while he himself was busy with the "food" of the little beast all day long, and finally died of depression and depression.

Before he died, Liu Ye's father could only entrust the little beast to his son, and told him not to abandon it, otherwise the poisonous oath made by the ancestor of the family would definitely be fulfilled on Liu Ye......

So, Liu Ye started his miserable career.

For decades, Liu Ye has been like a slave, all the spirit stone property in his hands has been used to buy the "rations" of the little beast, and he can't make ends meet!

In order to feed the little beast, Liu Ye once ventured into a place of extreme yin, but encountered a large number of powerful ghosts and ghosts, and almost lost his life.

So in Liu Ye's heart, he really loves and hates this little beast that has accompanied him for decades, and he has mixed feelings......

The final ending was to meet Xia Yin in Fang City, and found that someone was interested in the little beast, and Liu Ye, who was the eldest one, gave the little beast half sold and half gave it to Xia Yin, so he did not hesitate to take a golden book blood coupon inherited from the family!

According to the requirements of the ancestor Jindan overhaul, it is necessary to find a suitable owner for the little beast.

But for more than a thousand years, the family has never found an owner who is willing to make a contract with the little beast, which shows how tricky this little beast is!

Because Liu Ye was no longer able to provide for it, seeing that the little beast was about to starve to death, where could he manage whether it was suitable or not, he caught Xia Yin and sent the little ancestor out......

......

Putting away the jade slip, Xia Yin had an expression on his face.

When I first saw the little beast devouring the demonic qi in the flying sword, I guessed the magical ability of this yin devouring beast!

Next, I can finally test whether this mysterious aura in my body is what I imagined......

As soon as Xia Yin's mind moved, the little beast in the distance immediately felt a sense in his heart, turned into an afterimage, and threw himself directly into Xia Yin's arms.

"Hehe, little guy, I want your help now!" Xia Yin muttered to himself as he looked at the little beast.

Although the little beast can't speak, it can feel what the master thinks through the mental connection, a pair of round eyes quietly look at the master, and there is a sense of excitement that is eager to try, but the two front paws are still holding on to the pill that has not been eaten, and keep rubbing Xia Yin's arm with his head......

Seeing that this little guy was ready, the expression on Xia Yin's face became a little worried.

But in the end, Xia Yin still opened the Five Qi Guiyuan Gong......

A powerful mana in his body spurted out in an instant!

An incomparably tyrannical aura escaped from Xia Yin's body.

And Xia Yin's gaze was staring at the little beast, and he didn't dare to blink his eyes......

Sensing the tyrannical aura on the master's body, the little beast that was still coquettish in Xia Yin's arms just now, the hairs on his body suddenly stood up, his mouth squeaked rapidly, his round eyes showed an extremely eager look, and there was some hesitation......

After hesitating for a moment, the little beast suddenly opened its big mouth, its round belly quickly dried up, and it sucked it violently......

Xia Yin instantly sensed that the tyrannical aura that had escaped from his body suddenly disappeared without a trace!

After the little beast took a sharp breath, its belly seemed to be inflated, and it quickly swelled and rounded, and it burped several times in a row.

The little beast had just eaten two pills, and it was already full, and now it has a "plus meal", and it is obviously overwhelmed!

As the little beast closed its mouth, the tyrannical aura that had just disappeared filled around Xia Yin's body again......

Xia Yin's face instantly became extremely ugly!

"I really didn't guess wrong, this tyrannical aura in the body turned out to be demonic qi, and judging from the phenomenon that the little beast can't stand it after swallowing a mouthful, it is still pure demonic qi to the extreme!"

Xia Yin's brows furrowed deeply, and his face became extremely solemn.

In my mind, I couldn't help but think of the experience of obtaining mysterious shoots in the Forbidden Land Cave Heavenly Remnant Hall......

The thing shaped like a hole on the altar of the remnant hall is definitely an ancient thing, and it is the key to suppressing the demonic qi monsters.

It is conceivable that with the passage of hundreds of thousands of years or even longer, while the "Dong Xiao" successfully suppressed the monsters, it itself slowly decayed, after all, everything is so vulnerable in the face of time......

And the demonic qi is eroding this "cave flute" antiquity all the time.

After a long time, the underground demonic energy has successfully demonized this antiquity that suppressed "oneself".

And the demonized "cave flute" has derived mysterious shoots.

It's just that this sprout is actually a magic tree, but it has also inherited all or part of the functions of the cave flute antiquities, and the ripening elixir is one of the anti-heaven functions, as for whether there are other effects, it is unknown for the time being......

As a magic tree, the young shoots absorb the stars and moonlight in the sky and turn into a liquid that ripens the elixir, which naturally also contains demonic energy, and the elixir that is matured by the liquid is the same, which contains extremely pure demonic energy.

And if you use these elixirs to refine and take them, you can't avoid inhaling a large amount of demonic qi into your body......

......

With the combing of the whole thing, Xia Yin finally understood what the tyrannical aura in his body was and where it came from!

"It's no wonder that the effect of these pills I took is far more than ten times that of ordinary pills, it turns out that they contain pure demonic energy!"

Xia Yin muttered to himself with a pale face.

Since he had several life-and-death battles with the Demon Sect monks, Xia Yin deliberately consulted the classics about demonic energy.

Compared to the ordinary heaven and earth aura, the power of the demonic qi is indeed many times stronger!

The reason why the Demon Dao Cultivators are several times stronger than the Righteous Dao Cultivators under the same realm of cultivation is because they contain demonic energy in their bodies!

And now that I have been eating the elixir containing demonic energy for more than a year, the demonic qi in my body has accumulated to a terrifying amount!
