"Take the essence blood as the guide, integrate into the magic weapon...."Ling Feng sat cross-legged on the stone platform, the magic weapon soul bell was suspended in front of him, cut his fingers, a drop of blood with a seven-colored light slowly floated up, after this drop of blood left the body, Ling Feng's face was a little pale, this is not ordinary blood, but essence blood, containing Ling Feng's true power essence, ordinary blood is generally used to recognize the master, and if you want to carry out the art of blood refining, you must use essence blood.

The blood is blood-red all over, and there are seven-colored streamers floating around, suspended in the air, but not like human blood, but like a gem, dazzling, the soul bell floats in front of him, this drop of essence blood slowly blends into it, and suddenly, the original dark black soul bell bursts out with amazing seven-colored light, illuminating the dark cave, and in this way, the first step of the blood refining technique is completed.

"The second step, induce the essence blood again, condense the blood seals, the six blood seals can be successfully refined, and the maximum can be condensed eighteen blood seals, and the magic weapon made by sacrificing and refining with eighteen blood seals is almost the same as the natal magic weapon....." Ling Feng hovered the mantra of the blood refining technique in his mind, and once again drew a drop of essence blood from the wound of his finger, and there was a sound in his mouth, and a series of magic seals began to form in his hands, which were all the methods of condensation recorded in the secret art of blood refining, and these blood seals must also be condensed with essence blood, and ordinary monks could condense six. Seven blood seals, and some talents with good talent can condense ten blood seals, but if you want to condense eleven or even the highest eighteen blood seals, it is not just a matter of talent, in addition to talent, there must be other factors to complement each other to condense eighteen blood seals.

According to the records in the jade slip, this blood refining technique not only requires talent, but also depends on the monk's own cultivation and physique, and the most important thing is the monk's own killing heart.

This blood refining technique is not a righteous path spell in the first place, this is a secret technique created through endless killing, if a cultivator does not have a killing heart, then no matter how good your talent is, no matter how high your cultivation is, no matter how strong your physique is, you will at most condense eleven or two blood seals, and Ling Feng is extremely confident in himself, although he may be a little worse in cultivation, but his talent, physique, and even killing heart, he will never be inferior to others.

"Blood, Evil, Hell, Soul, Darkness, Hell....." Ling Feng recited the Dharma decision in his mouth, and the Dharma seal in his hand kept changing, and the drop of essence blood in front of him also changed, and the blood began to twist, floating in mid-air, and soon, this drop of blood was condensed into a blood-colored mark, and it was the blood character written on it.

In addition to the red blood color, this blood seal also has seven colors of light coexisting, it is very good-looking, after the condensation of a blood seal, Ling Feng also did not stop, and soon, five blood seals were separated from the blood seal, a total of six big seals, namely: blood, evil, underworld, soul, ghost, and prison.

In this way, the minimum of the six blood seals was condensed, and the blood refining could already begin, but Ling Feng naturally could not be satisfied, the sacrifice of the six blood seals would not help his strength much at all, and his goal was to condense eighteen blood seals.

In this way, after Ling Feng condensed the six blood seals, he still did not stop, the law seals in his hands were still constantly changing, and there was a voice in his mouth: "Crime, punishment, refining, punishment, and precept..... " Eleven blood seals were condensed in one breath, and it was only at this time that the movements in Ling Feng's hands stopped, and he withdrew the law seals, and condensed eleven blood seals in one breath, which was also his current limit.

Eleven blood marks emitting seven-colored light floated around Ling Feng's body, this breath was also a big burden for Ling Feng, and the loss of true power in his body was also very large, but Ling Feng also got a lot of pills through killing enemies many times, including many pills for restoring true power, although Ling Feng was not short of time, but he also did not lack pills, so he was too lazy to recover his true power through meditation, he directly took out three Hui Qi Pills from the storage ring, swallowed it in his mouth, a warm current flowed through the five internal organs, and within the time of tea, the true power in Ling Feng's body was restored to ninety percent。

After the true power recovered, Ling Feng looked up at the eleven blood seals, in fact, it was already very good to be able to condense the eleven blood seals, but Ling Feng was not willing to stop there, he could feel that this was not his limit, thinking of this, Ling Feng no longer delayed, his hand began to change the seal method again, and his mouth began to recite the law again.

After condensing the ten blood seals, if you want to continue to condense it, it is not just a matter of talent, it is not easy to condense each blood seal after the ten paths, this process of condensing the blood seal at the same time tests the monk's talent, strength, physique, Dao heart and other aspects, if any of these elements are missing, it is extremely difficult to condense the eighteen blood seals.

began to condense the twelfth blood seal, at this time Ling Feng was no longer as relaxed as just now, but it didn't take much effort, the twelfth blood seal was also condensed, floating aside, but the next thirteenth and fourteenth blood seals, each condensing can make Ling Feng's true power consume five or six percent, and at the same time, the time spent has also greatly increased, Ling Feng is sending a handful of pills into his mouth at the moment, in order to supplement the consumption of true power.

When condensing the first to eleventh blood seals, Ling Feng was completely in one go, and the total time it took was less than one stick of incense, while it took half a pillar of incense to condense the twelfth blood seal Ling Feng, and the time spent condensing the thirteenth blood seal had already exceeded one stick of incense, and after successfully condensing the fourteenth blood seal, Ling Feng was already exhausted, not only the loss of true power, but also the consumption of his mind was also amazing.

When condensing the fifteenth blood seal, Ling Feng was already sweating profusely, but he still had no intention of giving up, his eyes were full of powerful obsession, Ling Feng was already an extremely persistent person in his bones, he couldn't cultivate back then, he was bullied all day long, he could persist for three years and never gave up cultivating immortals, how could these difficulties in front of him make him give up.

It took half an hour for Ling Feng to finally condense the fifteenth blood seal, send a large handful of pills to his mouth, rest for a while, Ling Feng began to condense again, but this time it was not so smooth, the sixteenth blood seal seemed to be stuck to the fifteenth blood seal, and it could not be condensed at all, which made Ling Feng anxious in his heart.

"What's going on?Why is the sixteenth blood seal so difficult?What's wrong?This technique of condensing the blood seal needs to test four aspects: cultivation, talent, physique and Dao heart, in terms of strength, I also have the late stage cultivation of the transcendent realm, and the blessing of chaotic true power, it shouldn't be too far behind, and in terms of talent, Ling Feng is also top-notch, let alone physique, I'm afraid that even the sect master of Xuanzong that day, the Dao Xuankong Law Body Li Xuankong can't compare to me in terms of physique, so there is only one last Dao heart left, isn't my Dao heart strong? Ling Feng was puzzled, his heart was definitely yearning for killing, but why was it still unsuccessful?

In this way, an hour passed, the sixteenth blood mark still hadn't been condensed, and at this moment, Ling Feng was no longer paranoid, from the initial anxiety to madness to calmness, Ling Feng was no longer as desperate as he was at the beginning.

"Perhaps..... It was me who was wrong. Ling Feng said to himself.

"My heart..... Is it really enlightened?" Ling Feng began to fall into deep thought.

"No, perhaps........ I didn't understand that my heart was ........"
