After another hour passed, the jet-black long knife finally turned into a red color, and after Long Feng felt the same, he controlled the jet-black long knife to break away from the red Yuan Fire and appear on a huge rock next to it.

I saw Long Feng slash in the palm of his hand, and a stream of red blood suddenly gushed out, flowing down his fingers, and the red blood dripped on the fiery long knife, making a sneering sound.

"Huh... Boom!"

Long Feng's blood-soaked palm stretched out his index and middle fingers, and his two fingers were together on the long knife and quickly drew strange runes.

Laugh at... The snort came out, with a burning smell into the nostrils, constantly enduring the pain of the fingers piercing the heart, the severe pain made the muscles on the face with a trace of twist, but it couldn't stop, it needed to be painted in one breath, otherwise it would fail, the hand kept flying and painted, and the blood formed a strange rune covering the long knife, and soon covered the long knife, almost staining the long knife with blood.

Finally, it was connected and combined into a huge rune, and after combining it into a rune, the entire long knife suddenly burst out with red blood light, and the bright red essence blood flowed, as if it had life, and the red essence blood rune circulated endlessly on the long knife, and after the long knife formed a rune, it was re-invested in the Yuan Huo under the control of Long Feng to continue refining.

The strange thing is that under the burning of the Yuan Huo, the blood runes covered with long knives, the Yuan Huo did not seem to have any effect on it, and it was not burned by the Yuan Huo.

Under the continuous burning and refining of the Yuan Fire, the blood runes gradually appeared and faded, which was absorbed by the long knife.

Long Feng's eyes suddenly darkened, and his head kept coming from bursts of dizziness, and he was lightheaded, as if he was about to fall down at any time, obviously because of the weakness brought by his body after the essence blood rune lost a large amount of essence blood.

Immediately biting the tip of his tongue, he forcibly lifted his spirit, now is not the time to fall, and Long Feng did not expect how difficult it would be.

Long Feng didn't want to think about it, not only did he have to control the formation, but he also had to concentrate desperately, otherwise he might fail, and he lost a lot of essence and blood without being dizzy, these were not at all what he could do at this time, and in the end, he fortunately completed the most difficult part.

As long as you can hold on, time passes minute by minute, and the essence blood runes covered with long knives are almost absorbed.

Long Feng had already felt that his consciousness was beginning to blur, he shook his head violently, and bit the tip of his tongue again, and suddenly a sharp pain hit, and he instantly felt much more sober.

Cheer up again, because now is the time to decide whether or not the Natal Divine Weapon can be successfully refined.

Long Feng's eyes stared at the long knife, for fear that something would go wrong, his breath suddenly stopped, and the blood runes were about to disappear, and suddenly his mind was running, and he observed carefully, and his eyes were watching the changes in the long knife.

After a while, his eyes suddenly widened, and when the rune disappeared, he bit the tip of his tongue and pointed at the long knife, spurting out a large mouthful of essence blood, which was mixed with the power of the soul, and sprayed on the long knife under the control of Long Feng.

"Snort... Whew!"

The essence blood sprinkled on the long knife made a sneering sound, the essence blood was like a hot liquid, and the rune was quickly absorbed by the long knife, after the essence blood and the rune were absorbed, the red light on the surface of the black long knife flashed, and a huge suction force came out in the long knife.

"Bang! bang!"

Under the huge suction power of the long knife, the Yuan stones of the entire formation exploded one after another, and the huge Yuan Qi and Yuan Huo were immediately absorbed by the long knife, but the suction of the long knife did not disappear, but increased the intensity of absorption.

A gust of wind blew out of thin air in the cave, and under the suction of the long knife, a wave of vitality was formed, and it quickly surged towards the black long knife.

Under the huge tide of vitality, Long Feng felt that his body was constantly shaking and unstable, and he hurriedly retreated away, and then his legs were firmly rooted on the ground, watching the long knife continue to absorb the vitality around him.

Long Feng knew that when the blood refining divine weapon was refined, it would absorb the surrounding Heaven and Earth Harvesting Yuan Qi to improve the quality of the Yuan Bing, and the more Yuan Qi absorbed, the higher the quality level of the Yuan Bing, but he didn't expect it to be so violent.

Long Feng was extremely happy, the more he absorbed, the better the quality of the long knife, Long Feng also put the yuan stones he took out before, all of them were thrown into the trend of vitality, one by one the yuan stones were shattering, although Long Feng knew that the yuan stones were precious, but he didn't have many concepts, he just hoped to improve the quality of the long knife as much as possible.

In fact, Long Feng didn't know that after the blood refining divine weapon was refined, it would absorb the vitality, but it would not absorb it like this, at most, it would absorb the vitality and fire of the formation.

And Long Feng didn't know, in fact, the Yuan Stone he took out was the best Yuan Stone mentioned outside, otherwise it would not be possible to compress and upgrade into a red Yuan Huo, and it was also the largest level of sacrificial spirit array, that energy was massive, if people knew that Long Feng was so wasteful, he didn't know how much blood he would vomit.

After the Yuan Stone was absorbed by thousands of stones, it began to slowly stop absorbing no more, and after the black long knife stopped absorbing the Yuan Qi, a strong light suddenly erupted, and a powerful power was transmitted, Long Feng felt a suppression, and after a while, the strong light disappeared and returned to calm, quietly suspended in mid-air.

Long Feng looked at the black long knife that was suspended in the air without falling to the ground, at least at the level of Yuan soldiers, only above the level of Yuan soldiers would be suspended in the air without landing.

Long Feng could feel the strong connection between himself and the long knife, and as soon as his mind moved, the black long knife suddenly turned into a black light and appeared in Zhong Feng's hand.

Long Feng looked at the long knife in his hand, it was still the same black as before, but inside the black knife, a trace of red veins faintly appeared, and Long Feng knew that it was the veins formed by the runes composed of his own blood.

Holding a long knife in his hand, he can clearly and strongly form a soul resonance, just like his own flesh and blood, which is not something that can be compared with the simple refining of the previous blood recognition master.

Long Feng knew that it was because of the essence blood and soul power that were spurted out when refining before, which was also the difference between the blood refining divine weapon and the ordinary master, because he added his own essence blood and soul power, it was a natal divine weapon that could intersect with his own life.

Long Feng was overjoyed, holding the black long knife in his hand, his heart was extremely excited, this is his future natal divine weapon, this will be the natal divine soldier that will accompany him for a lifetime, the long knife seems to be able to feel his own joy, faintly trembling, obviously has a strong spirituality.

Because of the soul power of Long Feng, as the spirituality of birth grows stronger in the future, it will eventually form a sword spirit and advance to the existence of a primordial spirit.

The reason why a spirit soldier is a spirit soldier is because of spirituality in order to become a spirit soldier, and the natal divine soldier is the easiest way to form spirituality.

It's not that ordinary Yuan soldiers can't produce spirituality, it's just that it's very difficult, and it requires a lot of factors.

Long Feng looked at the black long knife in his hand, and said to the long knife: You are the broken knife of the barren knife, which has been newly refined and forged by the respect of the Heavenly Desolate War, and has been soaked in the blood for endless years, you are the remnant of the barren knife, just like the new life of the barren knife, it has nothing to do with the barren knife, and it is no longer a barren knife from now on, you will be better than the barren knife because of the barren knife, and from now on there will only be the Panxue knife.

In the future, I will accompany me to kill the demon and kill the enemy, just like the desolate and desolate sword to fight against the desolate, will surpass the desolate desolate and desolate, and step on the peak to look down on all the spirits, I don't know if you are willing.

The long knife in Long Feng's hand, as if he could understand Zhong Feng, trembled violently in his hand, bursting out with jet-black light, and the long knife made a knife sound, as if in response, Long Feng could feel the joy of the Pan Blood Knife.

Okay! Okay, Long Feng's face flushed with joy, he didn't expect the knife to respond to him, although he was only at the level of a Yuan soldier, he was the most powerful Yuan soldier, and he was full of spirituality, he had reached the level of raising his spirit, and he believed that it would not be too long to become a spirit soldier.

Long Feng let go of Pan Blood, the long knife was suspended in the air, and as soon as his mind moved, he controlled Pan Blood to move around him, and then shot towards the rock wall in front of him, the rock wall was under the long knife, like tofu, and the blade of the knife was easily inserted into the rock wall, if it wasn't for Long Feng's hurried control, the handle of the knife would probably disappear into the rock wall.

"Whoosh!" "Whoosh!"

Under the control of Long Feng, Pan Blood went from slow to fast in the cave, and finally became a black light, flying fast in the cave, just because the flight was too fast, Long Feng was not well controlled, and from time to time it was inserted into the rock wall, leaving a series of knife marks on the surrounding rock wall.

"Whoosh!"

The long knife appeared in front of Long Feng, I don't know if it can fly with a weapon, Long Feng looked at Pan Xue and thought, why don't you give it a try, Zhong Feng will do it when he thinks of it.

Under the control of Long Feng, under the dragon one meter above the ground, Zhong Feng jumped up and immediately stepped on the long knife.

"Bang!"

Long Feng suddenly fell to the ground with a knife and a knife, I rely on it, Long Feng stood up and patted the dust on his body.

"Phew!"

Spit out the dust that he had just eaten in his mouth, Zhong Feng's face was flushed, he forgot to control the Pan Blood Knife just now, fortunately no one was there, otherwise they would have to let Tie Niu know that they would not be laughed to death.
