"Huh?"

When Wei Changfeng was observing the spirit pool, he suddenly found that there was another passage exit in the cave.

"Brother Yan, where does it lead over there?"

Yan Dashan looked in the direction of his finger, his face suddenly showed a trace of horror, and he said in a deep voice: "This cave leads to a very deep place in Longshou Volcano, I have been in it before, and it is very dangerous inside!"

On the other side of the passage is a magma river flowing with magma, and Yan Dashan has also encountered terrifying demon beasts.

"That's a fire dragon!"

He said with trepidation, "It was sleeping when I went in, otherwise."

"Brother Wei, if it is not necessary, you must not go in, it is still very safe here. ”

According to Yan Dashan's description, this fire dragon was huge, so it was unlikely that it would get out of the tunnel, but the situation was completely different when he ran over.

He was lucky at the time, but he couldn't be lucky all the time, so he went once and never went again.

Wei Changfeng knew that the Fire Jiao was at least at the level of a high-ranking demon beast, and according to Yan Dashan, the Fire Jiao Dragon he saw was probably not simple, and it was inside the Dragon Head Volcano, so it was even more impossible to provoke.

Therefore, Wei Changfeng quickly suppressed the thoughts that had just arisen in his heart, and at present, the most important thing for him was to break through the innate realm in the shortest possible time.

Once I enter the congenital, my life is up to me!

Taking a deep breath of the air full of flames, Wei Changfeng said in a deep voice: "Brother Yan, I'm going to stay here for a while, why don't you go back first?"

Since Yan Dashan brought him over. Of course I thought of this. Immediately smiled: "Okay." Brother Nawei, take care, Tiezhu and I are waiting for you in the village!"

He asked, "Do you recognize the way back?"

Wei Changfeng replied without thinking, "No problem!"

He has a very strong memory, and he can say that he has never forgotten it, so he has already remembered the road when he came, and he doesn't need Yan Dashan to turn back and lead the way.

And Wei Changfeng doesn't know how long he will stay here!

"Then be careful!"

Yan Dashan said: "When I go out, I will seal the entrance of the cave again." ”

He has a rough appearance, but his mind is more delicate. Think about the problem more thoughtfully.

"Thank you, Brother Yan!"

After saying goodbye, Yan Dashan quickly left the cave.

After he left, Wei Changfeng did not rush to go down to the spirit pool to cultivate, but along this spirit pool, he explored all the surrounding areas clearly.

Advancing to the Innate Great Realm is not a trivial matter, it will definitely not work without adequate preparation, for thousands of years, I don't know how many martial artists have been stuck in front of this level, and they will not be able to break through for the rest of their lives.

is not congenital, after all, it is a general generation among all living beings.

And this careful search. Wei Changfeng really made a discovery—he found a near-earth fire vein.

It is normal to find a leyline of earth fire in the heart of a volcano, but this leyline is very shallow from the surface rock layer. The fire breath came out of the stone of high quality, which was definitely a surprise for Wei Changfeng.

He simply sat down on this near-earth fire vein, took out the Dan Ding from the Sumeru Ring and placed it in front of him, and then took out the various spiritual materials stored in it and the Pig King Demon Pill in turn.

The Nine Treasures Yun Spirit Pill refined earlier had all been used, so Wei Changfeng planned to use this demon pill to refine a few more, borrow the spirit pill in the spirit pool, and impact the innate realm in a two-pronged way!

After the materials and objects were ready to stop, Wei Changfeng calmed down and urged the true yuan, gathering a stream of pure true qi in his right hand, in which the index finger and middle finger were put together in a sword shape and poked at the leyline.

Burst!

The invisible sword qi that leaked from his fingertips pierced through the solid rock in an instant, making a small hole.

This is called breaking the vein to make fire, and it is a step that must be completed by using the earth fire alchemy, but depending on the situation, there are various ways to break the vein, and there are many tools available.

Wei Changfeng didn't expect that he would be able to find the earth fire to use, so he didn't prepare the tools to break the veins, but now he is not as strong as he was back then.

Using his fingers as a sword to transform into invisible sword qi, it is naturally easy to deal with the rock skin, and it is very accurate!

The next moment, a beam of crimson earth fire flew up from under the rock formation, rushing upwards a full four or five feet high!

Wei Changfeng suddenly felt a scorching breath rushing towards his face, and he couldn't help but hold his breath to fight against it, so as not to be burned by the power of the earth fire.

Not only did he not feel the slightest fear, but he felt joy.

As Wei Changfeng had previously judged, the scale of this fire vein was not very large, but the quality was excellent.

He shrank back, reached out and grasped the claws in his hands, grabbed Danding with the help of the Dragon Soul Locking Divine Power, and dragged it to the earth fire.

Linglong Danding, like the Dingzhong in the palm, is a tool used by the Dan master to refine the Dan with his own Dan fire, and normally it cannot be refined by heating it with ground fire.

But what kind of person Wei Changfeng is, since he dares to break the pulse and make fire, of course he has his own means.

When the local fire flames licked the Linglong Dan Dingding, Wei Changfeng suddenly swung his left palm and slapped it on the ground in front of him, and at a position less than two inches away from the fire hole, he injected the incomparably pure Taixu Dan energy into the rock formation.

Most of the blazing earth fire was extinguished in an instant, turning the tangible into the invisible, and the color of the fire changed from red to almost transparent pale gold, evenly wrapping most of the Danding.

Invisible Danhuo!

This is one of the supreme methods of Dan Dao, which is to melt the Dan to transform the earth and fire, combine the power of the two to improve the quality of the fire, and is specially used to refine high-grade materials and high-level pills!

The main material of the Nine Treasures Yun Spirit Pill that Wei Changfeng is now using is the Pig King Demon Pill, the quality of this Demon Pill is nothing to say, it has definitely reached the level of the top grade, and the value cannot be measured by money.

But because its quality is so good, the difficulty of refining it increases exponentially.

If the usual Dan Fire was used for refining, Wei Changfeng estimated that it would take at least four or five times as long, and once there was a shortage of Dan strength, it was very likely that the refining would fail and the precious materials would be wasted.

Therefore, Wei Changfeng originally planned to refine the new Nine Treasures Essence Spirit Pill after breaking through the Taixu Nine Heavens Zhengyang Heart Technique to a higher realm, but now the situation is different.

With the help of this high-quality leyline, he was sure enough to refine the Pig King Demon Pill.

Under the calcination of the new Danhuo, the Linglong Danding was quickly heated to the extent that the surface body was white, and Wei Changfeng opened the lid of the Ding without thinking and put all the pre-prepared materials into it.

It also includes the demon pill of the Black Pig King!――
