Chen Nan continued to run the body refining technique, strengthen the body, broaden and stabilize the meridians, when a bucket of essence blood was absorbed, Chen Nan opened his eyes, he clearly felt that he had entered the late stage of the second heaven of body refining, coupled with his already strong body, it was actually equivalent to the cultivation of the third heaven of an ordinary body refiner, and the surrounding heat was no longer able to cause him any damage. Adapting to the magma environment, he can already clearly feel the existence of the core fire, and with a goal, he can also use it to refine his body, and he is even more full of motivation.

Suddenly, Chen Nan found that a golden dragon phantom appeared in the sea of knowledge, Chen Nan was stunned, is this because he has swallowed the essence blood of the dragon? But soon he found that this is not the snake Jiao, this is a real dragon, although this dragon is virtual, he can still vaguely see the five claws and extremely faint dragon horns.

Although Chen Nan didn't understand what was going on, he also knew that it should be related to the true dragon bloodline in the snake Jiao's body, and it might be a phantom derived from the true dragon bloodline in its body.

Chen Nan advanced again, and when he couldn't bear the heat around him, he swallowed the Jiaolong Essence Blood Refining Body again, until he swallowed the fifth bucket of Essence Blood, and he had already come to a distance of ten meters from the Earth's Core Fire. At this time, his Vajra Refining Body Technique had already entered the late stage of the Third Heaven.

Looking at the golden dragon phantom again, the shadow of the dragon has condensed a lot, and has initially had the outline of the dragon, and the yellow clouds are swirling in his own sea of knowledge, Chen Nan knows that the yellow cloud is his own refining and absorbing the wisp of innate earth breath in the Yin Demon Bead, and the vision formed in the sea of knowledge, and the golden dragon phantom is floating in the yellow clouds, looming.

"It won't really condense into a golden dragon soul!" Because this dragon is nourished by his own sea of knowledge, he has no ill will towards himself, and Chen Nan doesn't care too much.

Seeing that the fire in the heart of the earth was in sight, Chen Nan knew that he could not move forward anymore, the fire in the center of the earth was a spiritual thing, once he was frightened and escaped, it would be difficult to get it again with his current cultivation.

In front of the magma package, there is a circular space with a diameter of one foot, this space is not empty, but anything is close to being burned into a liquid state, in this circular space, a fire heart is purple, the periphery is yellow, and the beautiful flame that exudes a faint blue light around it is beating gently, it is its beating, which causes the surrounding magma to rise and fall regularly, which leads to the eruption of the geothermal fountain, and then was discovered by Chennan.

Chen Nan knew that unless the earth's core fire was refined and absorbed by himself, it would be a re-refining body, and it would be difficult for him to get close to the circular area with his current cultivation, the earth's core fire was the eighteenth place in the strange fire between heaven and earth, it belonged to the earth's fire, and it was also the most suitable flame for alchemy, and he didn't want to miss it.

The story records that the fire of the center of the earth was born in the depths of the earth, after countless tempering of the fire of the earth, fusion, compression, a hundred years of spirit, a thousand years of formation, when the completion of the fire, the heart of the fire is cyan, the outside is yellow, the power is unpredictable, can cause volcanic eruptions, has the power to destroy the heaven and earth.

And now this flame is purple, and there is a light blue halo around it, obviously it is far from Dacheng, if you want to go through countless years in Dacheng here, Chen Nan can't afford to wait, for him, this flame is enough for him at present.

Chen Nan played the trick of controlling the fire, opened up a vacant space around him, and swallowed a drop of the thirty drops of spiritual liquid that the ancestral ginseng gave him, and the essence that the ancestral ginseng threw out was the essence of the spiritual liquid, and the essence was incomparably abundant.

He has not yet reached the Dragon Transformation Realm, and it is impossible to collect the Earth's Heart Fire, but he has the Qinglian World, as long as he uses a medium to temporarily control the Earth's Heart Fire and bring it into the Qinglian World, the difficulty will be reduced a lot, and the medium he chose to collect the Earth's Heart Fire is Shennong Ding.

Although Shennong Ding is a Dan furnace, it is also a magic weapon, it can be big or small, by feeling, Chen Nan believes that it will never be worse than the big bell of the old monster of Jindan, he has to try it whether it works or not.

As soon as the spiritual liquid was swallowed, it turned into a surging aura and swam around his body, and Chen Nan immediately sacrificed the Shennong Ding, and quickly shrouded the fire in the center of the earth.

The geocentric fire was shrouded in it before it had time to escape, and the geocentric fire struggled with all its might, wanting to get rid of the shackles of Shennong Ding, Shennong Ding's body was burned red, and it seemed that it could turn into liquid at any time, and the true weather of Chennan The Yellow River burst its embankment and rushed to Shennong Ding, and he tried his best to control Shennong Ding and prevent it from breaking free.

A body of true qi was quickly exhausted, and if it weren't for the ancestral ginseng spiritual liquid that provided spiritual power for Chennan, it would have been freed from it long ago. Chen Nan controlled Ding and the earth's core fire to confront each other, during which he continued to swallow the ancestral ginseng spiritual liquid, the true qi was exhausted, and then replenished, after repeated tempering, his meridians became more and more wide and solid, and the sea of qi became more and more condensed.

One person and one fire confronted each other like this, control and counter-control, and unconsciously it had been half a month, during which Chen Nanzu swallowed ten ancestral ginseng spiritual liquid, you know, ancestral ginseng is the ancestor of the earth's veins, and the essence contained in a drop of spiritual liquid essence is unimaginable, although these spiritual fluids are consumed, they also expand his meridians, which is enough to stabilize his realm.

Shennong Ding also gradually adapted to the heat of the geocentric fire, and Chennan's control of Shennong Ding became more and more handy, when Shennong Ding and the geocentric fire reached a balance, Chen Nan quickly dragged the geocentric fire into the Qinglian world.

Qinglian seed is his world, where the heat of the earth's core fire has been suppressed, and his control of the earth's core fire is more stable, my territory is my master, in the Qinglian world, Shennong Ding can control the earth's core fire, the earth's core fire is difficult to break free, now what Chen Nan has to do is to find a quiet place to restore the true qi, and completely refine the earth's core fire.

He didn't know how long he had been underground, so in order not to worry the two sisters of Nalan Ruofei, the retreat technique was launched and quickly escaped upward.

When he went back, he didn't have to fight against the earthfire magma, and his speed was naturally extremely fast, and he came to the bottom of the spring in just one breath.

Next to the hot spring, the two sisters were sitting on the shore in a daze, Chen Nan escaped into the water and never came up again, more than a month had passed, and the two daughters were almost desperate. If it weren't for that persistent belief in their hearts, it would be difficult for the two to persevere.

During this time, the two of them also approached the spring one after another, but the swirling water washed them back in an instant, and it was difficult for them to dive into the spring, let alone bear the heat there.

The two sat at the water's edge, no one spoke, staring blankly at the water, but their hearts were mixed, and all kinds of benefits of Chennan continued to emerge, from acquaintance, acquaintance to mutual acceptance, to the last expedition to Changbai Mountain, a drop by drop appeared in the minds of the two daughters, and unconsciously their pink cheeks were full of tears.

"Wow!" As soon as the water surfaced, Chen Nan came out of the water and walked towards the shore.
