In those years when I was a mortal and a demon

More than a month later, Lu Yuan and Zhang Tie came to a certain sea area. There was a gray island more than a hundred miles in front of them.

Lava Island, according to legend, was formed by the eruption of an undersea volcano tens of thousands of years ago. To this day, the volcano under this island is still active, with small eruptions occurring every few decades.

"I'm afraid the person inside has a cultivation level in the middle stage of pill formation. I'll take action to deal with him later. Brother Zhang, please preside over the formation to prevent him from escaping."

"In the middle stage of pill formation, are you sure?"

"Don't worry, I also have the initial peak level of cultivation now, so it won't be a big problem to deal with him. Don't use the innate five element flags to set up the formation later. If there is too much movement, it will be bad if he finds out."

"Well, I have refined some other formation disks over the years, which are enough to trap monks below Nascent Soul." Zhang Tie nodded, then made a water-avoiding technique and plunged into the sea.

About a few hours later, a ray of fire flew out of the sea water, and Zhang Tie's voice came from inside.

"The formation has been set up."

Lu Yuan extinguished the fire and flew quickly towards the lava island. As the distance gets closer, the temperature in the air gets hotter and hotter.

On the outer edge of the island near the sea, there was still a little lush green vegetation. As he progressed, it gradually became sparse and became bare and barren.

By the end, most of the large and small stones in the mountains on the island showed a fiery red color. And on some mountain tops, you can vaguely see some large and small lava cracks, which are extremely red and spewing scorching hot wind and gray-white flying ash, a scene like a scorched hell in a furnace.

Lu Yuan slowly flew over the highest peak on the island. At the bottom of the giant peak, there was a large fiery red hole, and bursts of geothermal wind blew out from time to time.

......

Below the cave entrance is a fiery underground world.

The area here is hundreds of feet wide, but the most eye-catching thing is a lava lake that occupies more than half of the area. The fiery red slurry bubbles inside are constantly rolling and then bursting. It gives people a terrible feeling that if they don't get closer, they will be roasted and fucked.

Surrounding the lake is the reddish red rock ground, and from time to time, traces of flames shoot out from the gaps, causing the nearby air to distort due to the high temperature.

On a large raised rock in the center of the lava lake, a middle-aged man sat cross-legged. As he vomited, a layer of red clouds appeared on his body from time to time, giving him a somewhat mysterious look.

.......

Bu Xu is a monk with earth-fire spiritual roots in the middle stage of elixir formation. Only a cultivation career of less than three hundred years has led to his current cultivation level, which has made him famous in the local area for being proud of several sea areas.

Even many people nearby believed that he was one of the most promising monks to be promoted to the Nascent Soul stage in the Luan Xing Sea in the past hundred years.

Bu Xu enjoyed the awe, envious eyes and praise from others very much. It was also because of this that he was able to occupy this lava island alone.

Suddenly, Bu Xu seemed to notice something. He opened his tightly closed eyes and looked up.

Through his spiritual consciousness, he noticed that someone was peeking at him unabashedly from the top of the mountain.

"Who is it?" A trace of anger flashed across Bu Xu's eyebrows and he waved his hand. A stream of fiery red magma splashed out of the lava lake and spewed out along the entrance of the cave.

snort!

Lu Yuan punched in the air, and a golden fist shadow collided with the magma in the passage. The explosion produced by the two blasted a huge gap in the mountain passage.

"Who are you, how dare you destroy my place of cultivation! If you don't give Bu a satisfactory answer today, you will stay here forever!" Bu Xu saw Lu Yuan above through the blasted gap, and his consciousness flashed Scanning, he found that the other party's cultivation was only at the early stage of peak, and he was quite confident in his words.

"It doesn't matter who I am. I'm here today just to hand over the Void Sky Remnant Map and the Fire Dragon Insect in your hands. I won't embarrass you." Lu Yuan said clearly.

"Hahahaha, what a big tone! Who are you? Don't say I don't have these two things. Even if I do, I can't give them to you!" After Bu Xu heard Lu Yuan's words, he laughed wildly on the surface, but in his heart Startled.

When he was traveling that year, he happened to find an ancient "Yuan Yuan Dan" in the belly of a level four monster, which saved him more than a hundred years of hard training. I'm afraid he is still in the foundation building stage. I can't get in there.

But it was this elixir that allowed him to taste the sweetness of ancient elixirs. Therefore, he had already set his sights on Xutian Cauldron, the first secret treasure in the Chaos Xinghai.

Not only did he use ruthless means to snatch a piece of the Void Sky Broken Map from others, but he also bought a fire dragon insect at a high price in advance while others were not paying attention.

The next time the Xutian Palace opens, he will venture into the inner hall and use this insect to collect the top secret treasure Xutian Cauldron that shook the star sea. As long as he has the many treasures in the Xutian Cauldron and the rumored Sky-Building Pill, it is almost inevitable that he will break through to the Nascent Soul Stage.

However, he made these preparations in secret. Anyone who knew about this has been silenced by him. How did this person know about it?

Could it be that the previous extermination was not handled properly and something slipped through the net?

No matter what, if this person knows about it, he must not stay!

Bu Xu looked at Lu Yuan above him, his expression gloomy.

"Don't admit it? With your level of cultivation, you will die if you go to Xutian Palace. Why don't you give it to me and save a small life." Lu Yuan said coldly, his voice cold.

"It seems that your Excellency knows a lot, so I can give you the things. But it's not easy for me to get these things. Is it unreasonable for me to give them to you for free?" Bu Xu's face suddenly became embarrassed.

"Why do you want me to exchange? What do you want? Speaking of which, I am very poor." Lu Yuan raised his eyebrows. The contrast in Bu Xu's attitude before and after was quite big, which made him a little cautious.

"Fellow Taoist, you are joking. You have entered the elixir-forming stage at such an age. Who would believe you if you say you don't have any wealth!" Seeing Lu Yuan become cautious, Bu Xu smiled faintly.

Then the light flashed in his hand. He took out a slightly yellowed old brocade handkerchief and a fiery red insect that looked like an earthworm.

"The thing is right here. Fellow Taoist, you can either rob it based on your ability, or show enough sincerity to exchange it!" A hint of cunning flashed in Bu Xu's eyes.

"Okay, I can still afford some treasures and spiritual stones." Lu Yuan didn't expect Bu Xu to take out the things so happily, and then he flew into the volcano in a flash.

Seeing Lu Yuan fly in, a trace of imperceptible pride flashed across Bu Xu's lips. When Lu Yuan flew over the lava lake, he suddenly made a magic spell with both hands.

The flaming red magma on the lake surface immediately started churning, and red waves of lava flowed out and hit Lu Yuan.

At the same time, large red clouds surged out of Bu Xu's body. The red clouds divided into two streams. One stream burned towards the mainland with the magma, while the other stream surged into the sky, sealing the gap above the lava lake.

"Hahaha, boy, you've been fooled!" Bu Xu said with a ferocious smile. After so many years of cultivation, he is not a stupid person.

Although he is one level higher than Lu Yuan, in order to avoid future troubles, he must maximize his advantages.

That's why he took the initiative to show the remnant map of Xutian and the fire dragon insect to lure Lu Yuan down.

The technique he practices is Luan Xinghai's famous "Taiyang Jue". This technique is the top-level mental technique among Luan Xinghai's fire-based techniques that can be ranked among the top ten.

He used the Taiyang True Fire in this technique to turn countless enemies into ashes and send them into the endless abyss.

Now that the lava lake is his home court, he is naturally confident and feels that killing his opponents here will be a piece of cake.

"Go to hell!" Looking at Lu Yuan who was wrapped in lava and Taiyang True Fire, Bu Xu put away the remnant map of Xutian and the fire dragon insect, and said in a cold voice.

"I knew you had bad intentions!" Lu Yuan's voice came from the red clouds.

"It's not too late to know now. At least it will make you more thoughtful in your next life!" Bu Xu said sarcastically.

"Do you really think you've got me? Give me a break!" followed by Lu Yuan's roar.

Golden glows shot out from the red magma and glow, and soon the red glow and magma were shattered, revealing Lu Yuan, who was covered in golden light.

"How is this possible!" Bu Xu's face immediately turned ugly. The blow just now could be said to be his killing move, but it was broken so easily by this person. You must know that there was once a formidable enemy whose cultivation was also in the middle stage of pill formation, and he was killed by a sneak attack using this method.

"Nothing is impossible, hand over your things and I will spare your life!"

"Okay, I admire your magical power. Take the things!" Bu Xu raised his hand, and a ray of red light shined directly at Lu Yuan.

However, the red light suddenly swelled in the middle and turned into a fiery red spear more than two feet long. The spear's entire body was covered with a layer of dazzling red clouds, and it pierced hard.

"I don't know whether to live or die!" Lu Yuan faced the menacing spear without any fear on his face. With the magic power activated, the surface of both fists was covered with a layer of golden scales, and then they touched each other, making a harsh sound of metal clashing.

With a loud "boom", Lu Yuan punched the spear, blocking the seemingly powerful spear.

It's just that the fist itself also shone with golden light, not in a relaxed manner. Even Lu Yuan could clearly feel the faint tingling sensation coming from his fist.

Over there, Bu Xu saw that his magic weapon was blocked by Lu Yuan with just one hand, and he immediately became flustered. He quickly raised his magic power, hoping to stab Lu Yuan to the core with one shot.

Feeling that the power of the spear increased sharply, Lu Yuan did not dare to touch it head-on. He grabbed both fists at the same time and suddenly grabbed the spear in his hand.

"Break it!" Lu Yuan yelled, and the straight spear was bent ninety degrees in the blink of an eye!

However, the material of this spear seemed to be unusual. As soon as Lu Yuan regained some strength, the spear immediately returned to its original shape. Lu Yuan unbelievingly twisted the spear into various angles like a twist, but was unable to destroy it.

"My Fire Cloud Spear!" The magic weapon was damaged repeatedly, Bu Xu's mind attached to it was hurt, and a mouthful of blood spurted out. His killing moves were easily broken by Lu Yuan one after another, and now the magic weapon is also trapped. It's like pouring cold water on your head, and your heart is extremely cold.

However, Bu Xu was also a ruthless person. After several attempts to take back the magic weapon failed, a stern look flashed in his eyes and he used a magic formula.

Lu Yuan, who was holding the spear tightly, felt something was wrong. He noticed that the spiritual power in the spear was obviously agitated, and he immediately understood what was going on.

"I want to self-destruct the magic weapon, I'm dreaming!" Lu Yuan shot a golden light from his eyes and hit the spear, and used a secret method of spiritual consciousness in the Dayan Art to completely obliterate Bu Xu's mind attached to the magic weapon.

"Ah!" Bu Xu screamed after receiving this blow, and covered his head in pain.

However, knowing that something was wrong, he knew that he could not stay here for long, so he endured the headache and controlled a cloud of fire. Taking advantage of Lu Yuan's suppression of the violent spiritual power in the spear magic weapon, he quickly escaped from the crater.

As soon as he arrived over the lava island, he heard a loud bang from the crater and saw Lu Yuan coming out with his long gun in hand.

This frightened him out of his wits, and he didn't care, he just looked in one direction and ran.

But not far after flying out, I felt that the light was stagnant, and I could no longer move forward.

"Formation!" Bu Xu lost his voice.

At that moment, he was like an ant on a hot pot, struggling on the spot, all kinds of thoughts came to his mind, trying to find a way out.

Suddenly, he looked up at the sky. I saw a short, thick young man with a simple and honest face looking at him with a contented expression above him.

"M-Middle stage of pill formation!" A feeling of despair surged into Bu Xu's heart, and he realized that he had no way to escape.

"Fellow Taoist, I am willing to offer you the broken picture!" Bu Xu shouted anxiously.

"Ah!" A burning stinging feeling came from his chest. Bu Xu lowered his head and saw that his chest was pierced by a very familiar spear.

"I've given you many opportunities." Lu Yuan said coldly behind Bu Xu.

Bu Xu opened his mouth, just about to say something more. However, his body was burned into ashes by the red glow on his magic weapon and disappeared without a trace.

Lu Yuan caught the storage bag that fell from mid-air and threw the spear to Zhang Tie.

"This magic weapon is not bad. It is made from ten thousand years of molten gold in the volcano. It has the properties of earth and fire. You should be able to use it."

Then he checked Bu Xu's storage bag. In addition to the Xutian residual map and the fire dragon insect, although there were some other rare materials, most of them were fire-attributed things that Lu Yuan could not use.

However, God Lord Dayan, who was possessed by Zhang Tiezhen Banner, thought that the Ten Thousand Years Molten Gold was a good thing, so he asked Lu Yuan and the others to search for it in the volcano. The two had no choice but to return to the bottom of the lava lake.

Half a month later, the entire lava island suddenly shook violently.

With a bang, a stream of lava hundreds of feet thick spurted out. The entire island was torn apart by this magma and turned into several isolated island groups of different sizes.

Amid the volcanic ash that filled the sky, a large water-blue flag flew out. After escaping for more than a hundred miles, two men covered in scorched black bodies flew out from the banner.

"Damn it, Lord Dayan, did you do it on purpose? You want to burn us both to death?" Lu Yuan cursed and spit out a few balls of black air from his mouth.

He and Zhang Tie discovered a lot of ten-thousand-year-old molten gold at the bottom of the lava lake, and excavated a lot of it on the advice of Lord Dayan.

But what they didn't expect was that the ten thousand-year-old molten gold was actually used to seal the magma in the earth's crust. After they dug through it, it caused a complete eruption of the submarine volcano, blowing up the entire lava island.

If they hadn't hid in the flood flag at the first time, they would have been burned to the ground.

"You kid, you have the nerve to blame me? I said from the beginning, just dig a little bit, but you didn't let me dig through the bottom." Dayan Shenjun counterattacked.

"Didn't you say that this ten thousand-year-old molten gold can be used as a refining material for 'Barrett'? So I dug more."

"Are you so stubborn? But if you dig in one place, it won't explode!"

"Okay, such a big noise will definitely attract other people. We have to leave quickly." Zhang Tie stopped the quarrel between the two.

A few days later, many monks who heard the commotion came over. When they saw the appearance of the lava island, they were all surprised. He also speculated on the life and death of Bu Xu who practiced here, as well as the reasons for the eruption of the lava island volcano.
