The first thing he did when he entered the cave mansion, Lin Feng shot out a drop of essence blood from his body!

This drop of essence blood is the introductory blood oath that contains Mo Dongyu's mana, and the content of it is to swear allegiance to Mo Dongyu and Yidaomen, and the allegiance to Mo Dongyu is higher than the allegiance to Yidaomen!

Mo Dongyu's intentions are self-evident, when his interests conflict with Yidaomen, Lin Feng needs to be loyal to him first!

As the highest and most important ancestor of Yidaomen's cultivation, Mo Dongyu didn't seem to be confident in himself, he was worried that one day, Yidaomen would have a fission, so all Yidaomen disciples who had blood oaths related to him must first stand on his side.

Lin Feng, as Mo Dongyu's inner disciple, belonged to the few with the highest status among all the disciples of Yidaomen, and the entry blood oath was naturally stricter, and it was not an exaggeration to swear allegiance to death.

The blood oath is actually an extremely subtle existence, it has an extremely strong divine mind binding on the subject it bears, and the most severe and effective of them is the refuge blood oath, which not only controls the subject's divine thoughts, but also can judge its life and death!

However, too strict blood oath also has great restrictions on the subject of allegiance, so although the refuge blood oath is powerful, it is not suitable for use in sects and families, because no matter how strong a person's divine thoughts are, it is impossible to associate too many refuge blood oaths to serve him, and the main strength of the refuge blood oath continues to increase, and the occupation of the divine thoughts of the allegiance object will increase day by day!

Another point, because the blood oath of refuge is too severe, all monks are willing to become the object of bearing, the road of cultivation is already difficult and dangerous, and the power of life and death is controlled by others, which is obviously contrary to the freedom of heaven, such a monk will never be able to break through the shackles of fate, and naturally it is impossible to go too far, so even if he dies, no one is willing to bear such a blood oath.

Therefore, the refuge blood oath only exists in the servants of the low spiritual intelligence, for these servants, the restriction of the spiritual wisdom makes them greedy for life and afraid of death, and the human monk becomes their master, once they become servants, they will be enslaved for life, but the occupation of the divine mind by the refuge blood oath is indeed beyond imagination, so it is impossible for any monk to have too many servants.

In the cultivation realm, the most common is the entry blood oath, and because of the status of the disciple, the severity of the entry blood oath will also vary greatly, and the content will vary from person to person.

In the Xiuzhen sect, the disciples are divided into many classifications, such as personal transmission, inner room, sitting, inner door, elite, outer door, miscellaneous servants, guest seats, etc., according to the disciple's cultivation and identity level, the severity of the entry blood oath is strictly divided, and according to the rules and actual needs of the major sects, the content of the entry blood oath will also be strange.

The blood oath that Mo Dongyu imposed on Lin Feng was extremely simple, the only requirement was loyalty, but the specifications were extremely strict, with such a blood oath strength, once Lin Feng betrayed, his divine thoughts would definitely suffer fatal blows, especially when he was married, the resulting weakening of his divine thoughts would make him unable to pass through the heart magic realm, and isolate himself in the miserable realm where his divine thoughts were exhausted!

Therefore, the inner chamber or the disciples of the own lineage, in addition to being the descendants of the other party, have to be bound by extremely severe blood oaths, and it is precisely for this reason that some monks with arrogant personalities or strange qualifications would rather give up the coveted favorable conditions than become vassals and puppets of high-ranking monks.

It is not only a bondage, but also a trading bond, a bridge between the cultivation sect or high-level cultivators, and the disciples.

Therefore, the entry blood oath is actually a kind of trading chip, the blood oath with a strict level, the corresponding reward is naturally high, if the reward does not match the level, no one is willing to accept the shackles of the blood oath, which is also the reason why the rules of the sect are stricter, but the salary of the disciples is relatively high.

The blood oath that Mo Dongyu imposed on Lin Feng was impeccable, as a disciple of the inner room, he was loyal to Mo Dongyu and Yidaomen, but the severity and rank of the blood oath were far beyond Lin Feng's imagination!

What determines the level and severity of the blood oath is completely determined by the trace of spiritual power that Mo Dongyu injected into Lin Feng's blood drops! The greater the strength of the spiritual power, the higher the restriction on Lin Feng, and once he betrays the blood oath in the future, the wounds he will suffer will be more fatal!

Because the spiritual power was completely fused into the blood, as long as Lin Feng took it back, it would enter Lin Feng's sea of consciousness in a special mode, and quickly spread to every corner of his divine thoughts, warning Lin Feng at all times that it was a holy decree that could never be disobeyed!

It is precisely because of the existence of such a blood oath that Fu Dongchuan and others will be loyal to their duties, return from Luozhou thousands of miles away, and swear to escort the huge wealth of Yidaomen, without daring to embezzle a trace.

Mo Dongyu originally wanted to use this kind of stern blood oath to make Lin Feng like Fu Dongchuan and the others, become Yidaomen and his lifelong puppet, but Lin Feng felt the spiritual power that Mo Dongyu had entered into the essence blood at that time, he could have refused to accept it, but in the face of the suspicious Mo Dongyu, Lin Feng's refusal would only make him kill him sharply!

Mo Dongyu watched Lin Feng quietly fuse his spiritual power into the blood droplet, and then withdraw it into his body, and all his suspicions about Lin Feng disappeared, but he didn't know that in the cultivation realm, there was a left-path trickery that specialized in dealing with blood oaths, which was mastered and mastered by Lin Feng, and quietly cast it!

This Left Dao Trick is the ancient secret recorded in the Left Dao Blood Order: Extraction Technique!

Lin Feng had only used the Extraction Technique once, and that was when he was in Buyue City, and Lin Feng used it to dissolve the introductory blood oath that Jin Zhengyu had imposed on him, but at the beginning, Lin Feng was a guest disciple of the Jin Zhen clan, and Jin Zhengyu's strength was far inferior to Mo Dongyu in the middle of the Yuan Infant, so the strength of the introductory blood oath could not be compared with the current one at all!

However, before Lin Feng returned to the Yidao Sect, he had already made full preparations, and he had many kinds of refining left path materials in his hands, which could be used at any time, and one of them was the special medicinal powder needed for the Extraction Technique!

These medicinal powders were swallowed into Lin Feng's body in advance, and after enough time of refining, they could be completely integrated with his blood, and when the essence blood was taken out of the body, Lin Feng had already done his hands and feet in advance, and in that seemingly normal blood droplet, it contained a left-handed material with super medicinal power!

With the power of the Left Dao Trick, the medicinal power was completely hidden in the depths of the blood droplets, even a monk like Mo Dongyu and other mid-Yuan Infant Cultivators could not see the flaws in the blood breath at all, and when the blood droplets were withdrawn by Lin Feng, the powerful Liliang of the Left Dao Trickery began to explode in full force!

As soon as the medicinal power in the blood was urged, the trace of spiritual power that Mo Dongyu injected into it was quickly separated from the blood droplets, and then under the tolerance of the medicinal power, it was imprisoned in an independent area!

Then, Lin Feng took out a jade bottle from the Sumeru Illusion Ring, and after the cap was opened, a thick liquid slurry appeared, and Lin Feng took the blood oath in front of him directly into the jade bottle, and then there was a magical scene!

The liquid slurry inside the jade bottle directly extracted the left medicinal power in the blood droplets, as well as the trace of spiritual power sealed by the medicinal power, into the liquid slurry, while Lin Feng's natal essence blood floated to the surface of the liquid slurry!

When Lin Feng withdrew the blood droplets in the liquid slurry again, and the extraction technique had been completed, the trace of spiritual power that Mo Dongyu had played was forever sealed in the liquid slurry in the jade bottle, and Lin Feng's so-called entry blood oath no longer existed!

Depending on the strength of the blood oath, the type and quantity of materials used in the extraction technique will also vary, and those liquid slurries in the jade bottle, as well as the medicinal powder that Lin Feng had taken before, are the necessary materials to crack the high-level blood oath!

In order to deal with Mo Dongyu's powerful mana, Lin Feng did not arouse his vigilance, so he used the medicinal powder and liquid plasma he had accumulated before, and this consumption alone was enough to bankrupt most of the monks, because the financial resources involved exceeded nearly 100 million spirit stones!

The financial resources of nearly 100 million spirit stones may be insignificant to some major cultivators, but the left path materials involved in the extraction technique are extremely difficult to gather, and refining them into medicinal powder and liquid slurry is even more unattainable, because only in the left path blood order can there be specific methods and medicinal powder formulas for the extraction technique!
