When he saw the golden bag on the altar next to the skeleton, Lin Cheng had already guessed what it was.

Storage bags, most likely storage bags. The King of Dongshan, the prince of the King of Dongshan, and the county lord just now all had a bag hanging from their waists, although they didn't have it, but Lin Cheng still knew what it was. Although there was a slight difference in the color of the things in front of him, Lin Cheng had already decided in his heart that the bag was a storage bag.

One step and ten meters, two steps Lin Cheng had already stepped onto the altar, and he instinctively took a step back before his arm was raised.

At that moment, what I saw in front of me was still a black and gray altar, and when I stepped onto the altar, the scene in front of me immediately changed. No longer an altar, but a world of flames.

There was boiling magma everywhere, and flames rose from a lot of magma. The small ones are the size of a little finger cap, and the big ones are the size of a fist. The colors are cyan, orange, green, and blue. And in the center of these magma pools, there is the largest magma pool, and in the center of it is a small but very striking flame, purple!

"God favors, someone finally came here before the last consciousness of the old decay was about to disappear. The old man's voice resounded throughout the space from nowhere.

"The way of heaven, immortality, ethereal, if you are not careful, you will never recover. ”

"The old Dong Rui Heng, from the Dong Rui Clan, strayed into this unknown immortal mansion when he collected the Crystal of Time, and wanted to refine the purple flame, but he was burned by this unknown flame, causing the soul to collapse and not enter reincarnation. Fortunately, in the end, the time crystal was used to imprison time here. If you refine a spiritual fire, you will get everything from me. If you don't have a chance, the ban will be opened later, and you will follow in the footsteps of the old man. ”

"You tell me how to refine first!" Without surprise, surprise, or even thought, Lin Cheng immediately asked the essential question.

This...... It's a real problem, a very real one.

The method of refining spiritual fire is very simple, whether it is a sect disciple or a casual cultivator, as long as you enter the qi refining stage, the first thing to learn is how to collect spiritual grass, and the second thing to learn is some ordinary refining methods. However, Lin Cheng was neither a disciple of the sect, nor was he a casual cultivator, so it might be more appropriate to call it a wild cultivator.

The old voice didn't answer the question, after all, it was just a remnant of consciousness that was about to dissipate, and he was just following a fixed procedure. Obviously, the old man named Dong Ruiheng did not expect this to happen. This place is not impossible for cultivators to enter, since they are cultivators, they should know how to refine.

Airplanes......

It's not a buzz, but listening to it in Lin Cheng's heart is more terrifying than a buzzer. The world of flames, which had just been lifeless, seemed to come to life suddenly, and the scorching heat caused the air to flow rapidly, producing a palpitating roar, and a wave of heat swept in.

"Fight!"

Lin Cheng didn't have any time to hesitate at this moment, he had to refine a spiritual fire before it was roasted. As for how to refine it, that's a matter of what to do! At the very least, you have to hold the spiritual fire in your hand now.

Call......

Ten meters in one step, Lin Cheng's eyebrows and hair instantly burned in one step, and the leather armor on his body emitted a sneering sound, and it immediately changed from soft armor to hard armor.

With one foot on the ground, Lin Cheng's body shot into the air like an arrow from the string and shot towards the magma pool.

"Open!"

The points of the whole body suddenly burst out, and the spiritual power around the body gushed out.

Boom......

In the muffled sound, fragments of the leather armor on his body flew one by one, and the surging spiritual power instantly dispersed the heat around his body. The eyes that had just been closed suddenly opened, and the pitch-black eyes were no longer eyes, but two pitch-black flames, and even a faint black streamer drifted away from the corners of the eyes. This flame was the black fire that appeared in Lin Cheng's mind out of thin air two years ago, but at this moment he was completely unaware of the change in his eyes.

Burst......

A mouthful of blood spurted out, faster than its body under the stirring of spiritual power, but after the blood spurted out, it was suddenly steamed into a blood mist by the heat. But the blood mist was spewed out too fast by Lin Cheng, and it had already enveloped the blue flames in the magma pool before it could be evaporated.

At the same time, Lin Cheng's right hand was full of spiritual power, like a dragonfly fishing for the moon under the sea, and he scooped up the blue flame in his hand.

Spiritual power frantically surged to his feet. With a bang, the magma burst out in all directions, and the Lin Cheng Harrier turned over and crossed into the air to the outside of the magma pool. A series of actions did not drag the mud and water at all, if there was any hesitation, he would die without a place to be buried, even so, at this moment, Lin Cheng was already out of his body, and the skin of his whole body was dry and cracked into pieces, as if he was a body of scales.

Lin Cheng, who had fallen on the edge of the magma pool, still didn't have time to hesitate at this moment, and without hesitation, another mouthful of blood spurted towards the flames.

Since I don't know the method of refining, then I will use my hard work to irrigate!

Lin Cheng thought that simple. Time is so tight that you can't think of anything complicated.

But at this moment, something unexpected happened.

The black fire that had been silent in his mind suddenly flickered, just a simple beat, but it had a great attraction. The blue flame in the palm of his right hand disappeared without a trace.

Lin Cheng's face changed instantly, although he didn't know how to refine, he could guess that it would definitely not be so simple. When he looked up at the red flame closest to him, he almost instinctively rushed towards it, but immediately felt the changes around him.

The world of flames is still the world of flames, but even if there is a spiritual power to block it, it still feels like the scorching temperature is calm at this moment, and it only feels a faint warmth.

As soon as his heart moved, he immediately closed his eyes slightly and looked inwardly at the black fire in his mind.

The black fire was still the same black fire, but it used to be pure black, but now it was no longer pure black, but there was a little bit of blue in the center. What surprised him the most was that the veins in the black fire were only five simple before, but now they have extended one, and this one is being perfected rapidly.

It's a bit curious, but this is not the time to explore. Lin Cheng walked towards the pool of red flame magma. As the distance approached, the temperature felt around the body increased rapidly. About three zhang or so away from the magma pool, Lin Cheng quickly retreated. He could feel that the temperature there was definitely not something he could resist now.

Taking advantage of this time, Lin Cheng had the heart to take a closer look at this space.

This space is very large, with a radius of about five or six hundred miles, among which there are more than 300 large and small magma pools, but some magma pools are colorful and different, and most of the magma pools have no flames, and it is already very dense to have two flames in their position.

Further afield......

Lin Cheng's eyes were slightly condensed, it seemed to be an altar.

Walking along the edge of the world of flames, he eventually had to give up the idea of going to the altar.

Just when he was at a loss, suddenly there was a light fluctuation in his mind, Lin Cheng entered the state of inner vision, and immediately found that the sixth vein of the black fire had been completed, and a dark blue flame was suspended there next to the black fire. A blood-linked breath arises spontaneously.

"Come out!"

After a moment of silence, his mind moved, and a dark blue flame appeared in the palm of his right hand out of thin air. At the same time, there was another trance, Lin Cheng's body had reappeared on the altar in the cave, and the skeleton sitting cross-legged in front of him slowly turned its head, and there seemed to be a will in the empty eye sockets that made people unable to resist anything.

At the same time, the old man's voice resounded in all directions again: "Congratulations on passing the first level." Only by refining the spiritual fire can you get all the things that the old man has. Although the old man is detached, he also has worries and regrets. Since you have arrived here is your chance, the old man does not ask you to return all this to Dong Rui's, but only asks him to give him a piece of the crystal of time, and only asks him to help Dong Rui's once as much as he can on this opportunity. ”

"Three drops of essence blood dripping into the space crystal can control the cave, the old decay has a wealth and a lifetime experience in the storage bag, and a drop of essence blood can be used. Well, the old decay has no worries to look away from. ”

As the sound disappeared, the space fell silent, and those demon bees did not rush into the altar, which made Lin Cheng Chang exhale.

Slowly inhaling a breath, Lin Cheng knelt on the altar.

"Thank you for the old man's care, although I don't know where Dongrui's is, he will definitely fulfill the last wish of his predecessors one day. After finishing speaking, he kowtowed respectfully three times.

At this moment, the voice that had just disappeared suddenly resounded from the bottom of my heart: "The child can be taught, the old man can leave with peace of mind, one drop of essence blood can drop on the crystal of space, and two drops of this cave will collapse." ”

Before the words fell, the skeleton slowly dissipated, and for a moment only ashes remained.

Only then did Lin Cheng know that if he had no gratitude just now, then the result might be unpredictable.
