"Ha Luha! After entering the Dongyang Sect, after nearly half a year, he finally entered the cold ice cave without arousing anyone's suspicion!" Under the supervision of the people of the Law Enforcement Hall, Wu Feng smiled in his heart and walked into the cold ice cave step by step.

Seeing that there was hope for a breakthrough in the Yan Pulse, even the previous resentment against the Yan family was temporarily put to the back of his mind, and his heart was extremely happy.

"Cold!"

However, Wu Feng hadn't laughed enough, and the sudden cold air made him feel unbearable.

"My third-order spirit body, comparable to normal circumstances, the physical strength of a martial artist in the Spirit Martial Realm is extremely cold-resistant, but on the periphery of this cold ice cave, there is a feeling that it is difficult to resist, and it is worthy of being a place of death for punishment!"

At that moment, Wu Feng did not dare to be careless, and immediately moved the internal qi on the surface of his body to resist the erosion of the cold air.

"By the way, I don't know what the Iron Jade Dragon gave me? With a thought in his mind, Wu Feng remembered what Tie Yulong had given him before.

Opening the small cloth bag and taking out the contents inside, Wu Feng was startled.

"I really didn't expect it to be the 10,000-year-old fire spirit chalcedony!"

A fiery red jade plaque can be faintly seen dancing in the center, and there is a strong burning sensation in the hand.

Holding the fire spirit chalcedony, Wu Feng also stopped the operation of internal qi and maintained sufficient internal qi.

"It's really a good thing! Maybe the martial artist of the First Martial Realm holds this chalcedony, and it is still difficult to save his life in this cold ice cave, but if it is a martial artist with the ice and fire attribute physique of the True Martial Realm, he will definitely be able to get out alive. Wu Feng speculated.

"Huh?" Suddenly, Wu Feng found a little puzzled, and thought: "When Tie Yulong handed over the jade plate to me, there was no heat dissipation in the cloth bag, but outside the cloth bag, there was such a strong heat."

"Hehe, this cloth bag, but it's also a baby!" Wu Feng was pleasantly surprised, and found that the cloth bag could actually isolate the breath, and it was directly certain that neither the cold nor the heat could pass through the cloth bag.

"Tie Yulong said that this was taken from Tie Wuself, but I don't know where Tie Wuself got it? This 10,000-year-old fire spirit chalcedony is worth at least one of the local level martial arts, and it is definitely the most precious thing I have encountered in the Northeast Region. ”

Wu Feng was puzzled in his heart, but he didn't know that this 10,000-year-old fire spirit chalcedony was the heirloom of the Tie family, and it had been passed down for many generations, and now it was stolen and given away by Tie Yulong, a "not angry" guy.

Fortunately, Wu Feng has his own principles, he will not be greedy when he sees treasure, and he is ready to return it to Tie Yulong after he leaves.

"With my current third-order spirit body, I can have a better area for cold qi, and with the fire spirit chalcedony, I can move freely in the cold ice cave, and I won't waste my internal qi to drive away the cold, so I can look around and find a good place to derive my veins."

"By the way, there is no one now, you can release the dragon qi, but I don't know if the dragon qi can withstand the cold here. Long Qi's mother is a snow jade lion clan, and Long Qi also retains the characteristics of the lion clan, so it should be able to resist the cold! Even if it doesn't work, just take Long Qi back into the two beast rings. ”

Having made up his mind, Wu Feng released Long Qi.

"Roar!

As soon as Long Qi came out, he first screamed excitedly, and then circled around Wu Feng, rubbing Wu Feng's thigh with his body flatteringly.

"Long Qi, you?" Wu Feng called out to Long Qi, then pointed to the ice-covered cave, and then to the two beast rings on his wrists.

"Roar!" Long Qi shouted, then moved away from Wu Feng and jumped around on the ice.

"It seems that Long Qi likes the environment very much, and there is nothing uncomfortable with it. After making sure that Long Qi was not affected by the cold, Wu Feng was also relieved, and said to Qi: "You can play here, but you are not allowed to go out from there." ”

As he spoke, Wu Feng pointed to the passage between the ice cave and the ground

Half a day later, it was already night, and the cold in the ice cave began to intensify.

Wu Feng sat in an extremely cold corner of the cave room, about to start the second evolutionary vein.

"The holy veins of fire, the five elements of the human body, the liver belongs to wood, and the heart belongs to fire. I have already derived the Liver Wood Sacred Vein, and now I will derive the Heart Fire Holy Vein. ”

Derived from the Heart Fire Holy Vein, there is already a top-level spiritual object left by Ling Danchen-Molten Heart.

Wu Feng took out a cold ice jade box from the storage ring, which was the one that could isolate the aura and prevent the heart of the molten fire from spontaneously combusting.

"The reason why I came to the Cold Ice Cave to derive the vein is to suppress the backlash of the strong fire attribute spiritual power of the molten heart with the help of cold qi, and before the vein, first collect the fire spirit chalcedony"

Put the fire spirit chalcedony into a special cloth bag, and put it in the storage ring, Rao is Wu Feng was prepared, and he was also shivered by the cold.

After all, he was now in the depths of the third layer of the ice cave, and it was night, and the cold was even worse than when he first entered.

The reason why a spirit object is a spirit and nothing else is because of its unique nature.

Just like the previous Xuanmu Divine Crystal, it was transformed into wood, but it was not wood, rich in wood attribute aura, but it was not a crystal of aura condensation.

The heart of molten fire, which is generated in the fire of underground lava, has undergone essential transformation and is no longer fire, although it can be used as a fire when it is burned by aura, but its essence is a wood attribute spiritual object.

The attribute of spiritual objects is that they can be smelted.

At the beginning of the Martial Artist Earth Yuan Realm, to stimulate the acupuncture point, it is necessary to smelt spiritual objects, but it is different from the smelting of the Wufeng Yanmai.

In order to prevent the Molten Heart from burning with the aura, Wu Feng almost brought the Xuanbing Jade Box to his mouth, and then opened a small opening and swallowed the Molten Heart into his mouth.

Previously, Wu Feng also separated the true qi transformed by the essence qi in his body from the wood attribute aura, and operated the aura to his legs, and the places that might come into contact with the heart of the molten fire were all pure true qi. True Qi is fundamentally different from Reiki and does not burn.

This is also the reason why the martial artists under the Lingwu realm cannot produce the true fire in their bodies. The decline and loss of the high-level alchemy refiner in the Northeast Region is also due to this.

"Uh-huh!"

Swallowing the Heart of Molten Fire, Wu Feng snorted in pain in a dull manner, and then his face turned red.

For such a situation, Wu Feng had already thought about it many times in advance, and he did not lose his sense of proportion, and immediately started to run the technique of deriving the veins, and began to smelt the heart of the molten fire with his true qi.

Concentrate on calming the spirit, hold the yuan and keep one, turn the spirit into liquid, refine the liquid into qi, and melt the qi into the void

Concentrate and calm down, hold the yuan and keep one.

This is the most basic and important requirement of Derivation.

If you can't do it, you don't need the spirit to fight back, and you will go crazy first.

But the physical and mental pain that Yanmai brings, how can it be so easy to hold the yuan and keep one?

Holy vein?

What is the holy vein? It is the holy meridian.

The main meridians of the human body are the 12 meridians and the 8 meridians. These 20 meridians are the basis of martial arts, all of which are connected to the two dantian points in the sea of qi and the middle of the body, and the rest of the meridians of the human body are the branches of the twelve canons and the eight strange scriptures.

The 12 canons and the eight meridians are the most important meridians in the human body, and they cannot be called holy veins.

In the "Meridian Mixed Yuan Sutra", the method of derivation is to forcibly open up the holy meridians in the body with the help of top-level spiritual objects.

The first derivation of the Sacred Vein of Wood is to fuse the Wood Attribute Spirit Object into the liver and turn it into the Holy Wood Liver. Then, between the liver and the dantian, a special holy meridian is opened.

Liver Wood Sacred Vein, Wu Feng has Ling Danchen's help, and because of the gentle and vigorous nature of the wood attribute, although it is not very easy, it is also very smooth.

But this time, it was completely completed by Wu Feng alone, which can predict the difficulty and crisis.

"Okay, the heart of the molten fire has been operated to the heart, although the fire attribute spiritual power is chaotic, but there is no sign of burning, the first step is considered a success. Half an hour later, Wu Feng analyzed his own situation, and his baked red face slowly subsided.

But Wu Feng didn't dare to relax at all, because the Yanmai had just begun. This is different from last time, last time Ling Danchen directly melted the spirit object and entered it into Wu Feng's body, but this time he needed to melt it himself.

Refining spiritual objects into liquid is the second step of derivation.

After that, there is also the transformation of liquid into qi, and the melting of qi into the void can be regarded as completing the shaping of the holy heart. On the contrary, it is the most difficult to open up the holy vein, there is only pain, and there will be no crisis

Half an hour later, the Molten Heart began to melt into liquid.

After twelve hours, a third of the Molten Heart turned into liquid

Three days later, the liquid that the heart of the molten fire had turned into gas.

After another nine days, the liquid was completely converted into gas.

At this time, Wu Feng began to melt into the void, which would be the most critical process of the vein, and it was also the most dangerous time.

In the past, he could suppress the spiritual power with all his heart, but now he has to dedicate at least half of his mind to control the spiritual qi state and integrate it into the heart.

The heart is the most vulnerable part of the human body.

Fire is the most violent of the five elements.

These two factors increase the danger of derivation.

Because of the existence of the contract, perhaps Long Qi also felt Wu Feng's situation and was quietly waiting by Wu Feng's side

Another twelve days had passed, and the process of Wu Fengyan's veins melting into the void was about to be completed, but at this time, his mind was also extremely tired.

"Ah!" Wu Feng exclaimed in pain, first his mind was chaotic, and then the qi of the last part of the spiritual creatures also began to riot.

What's even more serious is that Wu Feng fell into a coma because of his exhaustion, and his body also fell on the ice.

"Roar!" At this moment, Long Qi suddenly got up and spat out a mouthful of ice yuan, covering the location of Wu Feng's heart.

That Ice Yuan is half of the Dragon Qi Natal Essence Element, half of the Ice Attribute Essence Element, which is equivalent to a quarter of the overall Essence Element. After spitting out the ice yuan, Long Qi also lay on the ground to recover.

Suppressed by that Bing Yuan, the spiritual qi in Wu Feng's heart also began to regain calm.

Fortunately, although Wu Feng was in a coma, he had been running the exercises of the Pulse Extension, which was also an obsession that he still insisted on when his mind was exhausted to the extreme, which was almost equivalent to instinct.

Falling asleep is also the best way to regain your spirit.

Nine days later, Wu Feng woke up, his spirit had fully recovered, and he was even more pleasantly surprised to find that he had completed the shaping of his heart in a coma.

His heart is now the heart of the Holy Fire.

Recalling the hazy feeling in the coma, Wu Feng also had some vague guesses in his heart when he saw Long Qi lying asleep and recovering not far from him.

Glancing at Long Qi gratefully, Wu Feng sat down cross-legged again, and began to take the last step of the vein, opening up the Heart Fire Sacred Vein.

The Holy Vein of Heart Fire, the holy meridian that connects the heart to the dantian. Wu Feng's cultivation exercises are at least the heavenly level, and the cultivation of the middle dantian and the middle acupoint, and opening up the holy vein is to connect the heart and the middle acupoint
