Yang Feng didn't care too much about this, after all, he was not determined to follow the path of Earth Immortal.

The reason why Yang Feng wanted to practice the skills of the Earth Immortal was just a temporary method to restore his magic power.

Moreover, because this technique has defects, the conditions for redemption are much simpler than the previous two techniques, and it only requires any material containing the power of the law to exchange.

After Yang Feng made up his mind, a green light flew out between his eyebrows, landed in the array plate, and then disappeared.

After waiting for about an hour, the light on the array plate flashed and a blue light cast into the secret room.

The green light fell, and a phantom man with a green mask appeared. He was very tall and was wearing a strange alien costume. He didn't look like a human.

The man asked, "Fellow Taoist, do you like my martial arts?"

Yang Feng asked directly: "Yes, according to your conditions, you can exchange any material containing the power of the law, but it does not specify the amount required. Please tell me carefully."

The tall man smiled and said, "Haha, the so-called martial arts scriptures can also be divided into high and low. Materials containing the power of laws naturally have levels. The specific exchange quantity depends on the quality of the items taken out by fellow Taoists?"

When Yang Feng heard this, he pondered for a moment, then flipped his wrist and a strange walnut with face patterns appeared in his palm.

As soon as this object is taken out, it immediately emits a strong earth-attribute aura.

"Fellow Taoist, let's take a look, how about exchanging this thing?"

Yang Feng glanced at the phantom man and asked.

Seeing this, the phantom man was stunned at first, subconsciously approached Yang Feng half a step, and then stopped immediately. He smiled lightly and said, "This earth-sun fruit does contain a trace of earth-attribute law power, but it is not very strong. If fellow Taoists exchange this thing, at least ten will be needed."

"It turns out that this thing is called Tusunguo..."

Yang Feng said in his heart, but there was no change in his face, and he was not in a hurry to speak. He just looked at the phantom man with his expression and said nothing.

The man sighed in his heart, thinking that the half step he had just taken had already seen his weakness and reality by Yang Feng, so he changed his words and said, "If a fellow Taoist has a better-quality Tu Sunguo, take out five of them, and I will bear the pain of giving up my love."

When Yang Feng heard this, he smiled slightly, poked out his two fingers, and said calmly: "Two."

"My fellow Taoist is a bit unkind. Although my "Black Sea Heavy Water Sutra" has a slight flaw, it is also a real high-level earth immortal technique. The two earth grandsons are definitely not able to exchange it."

The phantom man waved his hands repeatedly and said.

"Although this technique seems good, it is just a slight flaw? I'm afraid fellow Taoists know better than anyone else, right? I have to say that it is absolutely enough for me to exchange two rare spiritual fruits for a useless item." Yang Feng said with a roar

"The two earthen grandson fruits are not enough. Fellow Taoist, please add another one and exchange three for...how?"

The phantom man heard this and thought for a while, he said hesitantly.

"It's not impossible to add another one, but... fellow Taoist needs to answer me a question first."

After hearing this, Yang Feng said after pondering for a moment.

“Just answer one question?”

The phantom man was slightly stunned and said in confusion.

"Yes, I believe that fellow Taoists will know the answer to this question." Yang Feng said with a smile.

"Fellow Taoist, please ask."

The phantom man thought for a while and nodded and said.

"To be honest, although I accidentally got a few earthen fruits, I know very little about the efficacy of this thing. I hope my fellow Taoists can solve some of the doubts." Yang Feng said.

The phantom man was stunned when he heard this, and then said with a wry smile: "Fellow Taoist, I asked the right person. This fruit is a special one among the many earth-attribute spiritual fruits. When it comes to earth, it takes 100,000 years to sprout, a tree can be formed in a million years, and a million years to condense the power of the soil to bear fruit. It is an excellent material for refining the earth-powered immortal weapon and high-level Taoist soldiers."

"So that's it. Thank you for your advice. Let's complete the transaction." Yang Feng smiled slightly.

The phantom man didn't say anything more, just nodded silently.

So, the two of them raised their palms at the same time, and immediately something in each of them shot out, flying towards the vortex in the center of the formation plate.

The difference is that Yang Feng has three human-faced walnuts emitting a yellow halo, and the phantom man has an ancient book phantom.

Seeing three fruits flying into the vortex, the light flashed and disappeared.

After a while, another ray of light lit up on the array plate, and an ancient book with a blue-black cover slowly flew out of the circular vortex.

Yang Feng poked out his palm to catch the ancient book, immediately moved his mind, looked at the phantom man after a brief look, and found that there was nothing abnormal.

The other party had just checked three Tu Sun Guo, and hugged Yang Feng and said nothing. The figure shook slightly and disappeared.

Yang Feng smiled, knowing that the other party felt a little frustrated after suffering a secret loss, so he didn't care. After putting away the ancient books, his eyes turned to the formation plate again.

With the high-level earth immortal skills, we still have to refine the materials for the incarnation of the earth god.

Yang Feng originally planned to use this earth-sun fruit as the main material for refining the incarnation of the earth god, but now that he has decided to practice the "Black Sea Heavy Water Sutra", he naturally cannot use this fruit. He needs to find the main material containing the law of water.

Now it seems that this should not be a difficult task.

He raised his hand to the bartering place on the array plate, then put the earthen fruit on it, marking the requirements for materials containing the water attribute law.

Judging from the current performance, although this Impermanence Alliance seems mysterious, its sphere of influence is obviously not limited to the Black Wind Sea, and there should be a large number of members in the alliance, otherwise it would be impossible to form such a huge transaction scale and category.

In other words, since the earth-sun fruit is a precious earth-attribute spiritual fruit, it should not be difficult to exchange for materials that contain the same law of water.

After doing this, Yang Feng waved his hand to remove the phantom of the green light array in front of him, then sat cross-legged, took out the book "Black Sea Heavy Water Sutra", and carefully read and comprehend it.

As he expected, within seven or eight days, several people contacted each other through masks and expressed their desire to exchange.

Yang Feng did not trade immediately, but waited for several days, and then compared more than ten kinds of materials repeatedly, and then decided to choose a material called "Ninghai Crystal".

The law of water contained in this object is very similar, and it is very consistent with the technique of "Black Sea Heavy Water Sutra". It is said that a small piece of fingernail can condense the essence of the vast ocean water in a radius of thousands of miles. Therefore, this object is far more precious than that of Tu Sunguo. He almost used up the remaining Tu Sunguo on hand, and even put some other spiritual materials on it, so he could persuade the other party to exchange for this object that was barely enough.

After everything was ready, Yang Feng immediately began to retreat.

Spring goes and autumn comes. For more than a year, it is almost a blink of an eye for the fairy world.

During this period, Yang Feng continued to cultivate soul flowers through green liquid on the one hand, and at the same time he comprehended the Black Sea Heavy Water Sutra day and night, making final preparations for refining the earth incarnation.

On this day, somewhere under the sea thousands of miles away from Wudao.

The ground at the bottom of the sea here is uneven, with rocks like mountains standing on it. At first glance, it looks like a mountain range on the bottom of the sea.

These rocks are dark red, with uneven surfaces, and are formed after magma is cooled.

You can vaguely see black holes under the sea, dark and faint, and you don’t know where to go.

This is a group of undersea volcanoes, with huge volcanoes often erupting, so few people come.

A large, hemispherical blue shield was opened on the flat ground somewhere under the sea, which was isolated from the outside, and the situation inside could not be seen clearly from the outside.

Inside the magic circle, a figure in the green robe sat cross-legged in the center, which was Yang Feng.

Around it, more than ten huge stone pillars stand scattered, and in the middle is a fire-attribute magic array depicted with red runes.

After a long time, he slowly opened his eyes and started to mutter with a serious expression.

The red formation under him suddenly buzzed, and more than a dozen stone pillars around him burst out with dazzling red light, which shone through the surrounding blue shield, making the seabed within a radius of several miles bright.

He made gestures in his hand, and as the formation was running, the surrounding ground began to rumble.

After a moment, he yelled softly.

Click!

The center of the formation was about a meter in the radius, and there was no inscribed array pattern. Cracked suddenly appeared, revealing a large hole.

There was a bright red inside, and from here you could clearly see the rolling magma not far from the ground, as well as the rolling flames attached to the magma.

These flames showed a faint red gold color. They were not ordinary magma earth fire, but a kind of strange fire called deep sea earth fire. They can blend and coexist with sea water, and are more than several times stronger than ordinary earth fire.

A strange heat force spread out from the cave, and the surrounding sea water rolled.

Yang Feng appeared near the entrance of the cave in a flash. After sitting cross-legged again, his hands and ten fingers bounced out of the air.

The surrounding formations suddenly ran a little faster, emitting dazzling red light, pouring into the cave entrance.

The magma underground also fluctuated and slowly rushed towards the entrance of the cave.

With a "puff", a thick and light golden flame suddenly erupted from the hole on the ground, and it spiraled around and rushed out seven or eight feet high, like a violent fountain of flames, which could burst at any time.

Yang Feng's face turned solemn, and the magic in his hand could not help but speed up a little bit. The light of the surrounding formation became even stronger, and wisps of red light flew out of the formation, wrapping up the light golden earth fire.

The surging earth fire suddenly became softer, like a wild horse, slowly tamed, and as he pinched his fingers, it changed into various shapes extremely flexibly.

Seeing this, Yang Feng's face gradually relaxed a little. With a wave of his arm, a row of various materials appeared beside him.

With his current level of magic power, it is impossible to refine these materials, so with a sudden inspiration, he thought of using the power of deep sea and earth fire.

With a wave of his hand, a piece of white crystalline ore material flew out and sank into the earth fire.

He pinched his fingers, controlled the flames, and wrapped the material.

After a while, the white crystalline ore slowly melted and turned into a translucent white liquid.

After a brief observation, he waved one hand again, and another piece of material flew out and sank into the flames...

In a blink of an eye, a month passed.

The materials around Yang Feng have now basically been put into the earth fire flames. They have been refined and mixed together to form a light blue ball the size of a millstone, which gently rolls in the flames.

His face was a little pale. He turned his hand and took out a cloud crane grass and took it. His face slowly recovered. He waved his hand and took out a dark blue crystal as big as a bowl.

The crystal is crystal clear, and the pure blue light contained inside can be clearly seen from the outside, trembling gently like water waves, and the powerful fluctuations of the law of water emanate from the inside.

This thing is the sea crystal.

Yang Feng looked at the crystal in his hand deeply, took a deep breath, waved his hand and threw the object into the earth fire in front of him.

Under its control, the earth fire was covered with layers of layers, rolling around the dark blue crystals.

At this moment, a layer of light blue water suddenly appeared on the surface of the crystal, flowing constantly, making the whole stone look like a small ball of clear water, crystal clear.

The deep-sea earth fire, which is sufficiently meltable gold and iron, is immediately isolated by this seemingly ordinary light blue water light and cannot invade it.
