Yi Feng, who entered the cave, took out the scroll he obtained. Begin to read it seriously.

At this time, Yi Feng was already considered a master of martial arts. Although the things on the scroll are jerky and difficult to understand, it is also difficult for Yi Feng. Although it took some time, Yi Feng could understand it.

Yi Feng seriously looked at every word on the scroll repeatedly, and it was a big thing for the Immortal Sword to recognize the master. Yi Feng didn't dare to be sloppy in the slightest, and most importantly, it was related to his return to the mainland.

After Yi Feng studied it seriously for more than half a month, Yi Feng exhaled lightly and took the scroll back into the ring, recalling the contents of the scroll in his mind.

After feeling that he had not missed anything, he reached out and removed the black cloth from his arm. At the moment when the black cloth was removed, Yi Feng's arm once again shone with dazzling light.

Looking at the Zhuxian Sword tattoo that radiated light on his arm, Yi Feng's finger seal knotted wildly. The mudras are cumbersome and fast, and only the shadows of the handprints are left in the void.

And when Yi Feng's handprint was knotted, the surrounding energy converged in the direction of Yi Feng. However, the energy gathered did not enter Yi Feng's body, but instead converged in Yi Feng's handprint.

As more and more energy gathered around him, Yi Feng swiped slightly towards his fingers. Under Yi Feng's stroke, Yi Feng's finger slowly overflowed a drop of blood. In the case of this drop of blood gushing out, the space is also slightly distorted under the trembling blood, which shows how surging power this drop of blood has.

When this drop of blood was completely suspended in Yi Feng's handprint, all the energy that had been gathered rushed towards the blood of this place, and this drop of scarlet blood was even more dazzling and scarlet under the influx of spiritual energy.

When the converging power completely poured into the bloodstream, this drop needed to be doubled. It was as if the power of terror would erupt in the next moment.

Yi Feng looked at the blood that was a little uncontrollable, and then slowly moved towards Yi Feng's arm. When Yi Feng's goblin blood approached the light of the Zhuxian Sword, this drop of blood instantly turned into a blood mist, turned into the shape of the Zhuxian Sword's tattoo, and went towards the Zhuxian Sword.

The original light of the Immortal Sword was instantly covered by Yi Feng's essence blood mist.

And when Yi Feng's essence blood was completely integrated into the tattoo, Yi Feng felt a pain of cutting flesh. It's like a tattoo is going to be cut off.

Under this pain, the original tattoo slowly came out.

Looking at the slowly protruding tattoo on his arm, Yi Feng held his breath, and the blood mist was all integrated into it.

At this time, the tattoo disappeared violently, and Yi Feng's arm returned to smoothness again. In front of Yi Feng, a sharp sword appeared, and above the sharp sword, there was a flash of blood.

One gave a copy to look at the Zhuxian Sword that appeared in the void, and his eyes lit up violently: "There is a play." ”

Normally, Yi Feng couldn't force the Zhuxian Sword out of his arm, but this time he used the blood sacrifice method to force the Zhuxian Sword out. If the Zhuxian Sword can be forced out with this method, then there will be hope for Yi Feng to get out of the secret realm. At least, holding the Zhuxian Sword, Yi Feng had the confidence to break through the light film.

However, since this blood sacrifice method can force out the Zhuxian Sword, it can be said to be useful. Maybe it can really make Zhuxian Sword recognize the master.

Thinking of this, Yi Feng was naturally reluctant to give up this opportunity so easily, looking at the Zhuxian Sword suspended above the void, the seal knot on his hand was frantically knotted again.

At the moment when Yi Feng's fingers frantically knotted, the aura from the outside world continued to surge towards the cave. This terrifying aura converged in Yi Feng's handprint, and finally formed a series of substantial handprint patterns.

At the same time as these handprint patterns appeared, a drop of essence blood appeared on Yi Feng's finger again. Looking at the essence blood that emerged, Yi Feng's face was solemn. Essence blood is extremely important for martial artists, especially for saint-rank powerhouses, and it is even more difficult to recover.

However, in order to punish the immortal sword, Yi Feng was willing to pay such a price.

At the moment when the essence blood appeared, the handprint patterns poured towards the essence blood.

When all the spiritual energy poured into the essence blood, Yi Feng's eyes were a little condensed, and the original essence blood suddenly burst open, covering the body of the Zhuxian Sword, and all of them were integrated into it.

After these essence and blood were integrated into it, Yi Feng's fingers were still changing. Under Yi Feng's transformation, the original handprint pattern appeared on the sword body of the Zhuxian Sword, and then immediately turned into a raging flame and began to bake the Zhuxian Sword frantically.

Under the roasting of the flames, the Zhuxian Sword was obviously restless and began to tremble wildly. A great resistance surged towards those flames, and these flames were quickly weakened by such power, and only a little spark remained.

When Yi Feng saw this scene, the symbiotic energy in his body burst out, and under the surging of symbiotic energy into the flames, the flames soared wildly again. The raging flames continued to bake the Zhuxian Sword.

Yi Feng also used Xiang Ke energy to suppress the counterattack of the Zhuxian Sword, but the power of the Zhuxian Sword was extremely terrifying. is not inferior to him at all, and under Yi Feng's crazy suppression, he can't be suppressed either.

"Damn!" Yi Feng scolded angrily, looking at the flames that were shrinking again, the seal knot in his hand was frantically knotted again, and a drop of essence blood appeared in his hand, and then entered the Zhuxian Sword.

Under Yi Feng's continuous essence blood, the flame could finally ensure that it would not weaken. The body of the Zhuxian Sword also emitted a fiery aura.

And Yi Feng used such a terrifying essence blood, Yi Feng's face gradually turned pale. Such a crazy consumption of essence and blood, even if it was a saint level, had an equally great impact.

However, Yi Feng, who had already used his essence blood to refine the Immortal Sword, naturally would not give up halfway. Although such a consumption of essence blood may leave a terrifying dark disease, there is no other choice.

Normally, it would take more than a year to recover a drop of Holy Rank essence blood. And a desperate use of essence blood like Yi Feng is no longer something that time can easily recover.

The Zhuxian Sword is far more difficult to deal with than other spiritual weapons, according to the scroll. A normal high-level spiritual weapon, with five drops of essence blood, is enough to refine. However, Yi Feng far exceeded five drops of essence blood.

The flames on the Zhuxian Sword were still continuous, and Yi Feng's essence blood entered the Zhuxian Sword like a stream of water, and was completely devoured by the Zhuxian Sword. Yi Feng's whole person began to lose weight. Bones began to be exposed, and the skin was yellow. It seems to be back to the time to save Butterfly Rhyme and Purple Sound again.

And the power of the two laws in Yi Feng's body also constantly cooperated with the blood sacrifice of essence blood.
