The Heavenly Fire Domain is very famous, but it is also a place where dyeing white cold leaves makes you angry when you think about it.

It was here that he was forced away by the people of the Ice and Fire Sect. Let him be separated from Mumu.

After that time, he hadn't seen Mu Mu or heard from the other party.

Bai Lengye had always remembered the enemy of the Ice and Fire Sect in his heart, if it weren't for his lack of strength, he would definitely go to the other party to fight hard.

A few days later, Bai Lengye finally came to the Heavenly Fire Domain, and after coming here, Mu Yanran's strength was suppressed by a layer, and she accepted the inheritance of the Snow God. Only in the extreme cold can you exert more power, and in this hot place, the strength will be limited.

However, Bai Lengye felt that his strength had improved a little, he only felt this way after devouring the Nether Fire, on the surface, he was the strength of the fourth level of the Cave Void, but now he had a feeling that he was not afraid of people who met the sixth or seventh level of the Cave Void.

The Heavenly Fire Domain is very large, although there are many Heavenly Fires born, but not all Heavenly Fires can be absorbed and devoured.

For example, one night, Bai Leng Ye saw a kind of flame in the void, and that kind of flame was moonlight. After he tried to absorb it, he didn't expect to be repelled by his own heavenly fire, and he made him vomit blood.

Since then, the white cold leaf has known. Not all the heavenly fires he can absorb, but not those born in the void. Only those on the ground are allowed.

In this way, Bai Lengye and Mu Yanran had been wandering around the periphery of the Heavenly Fire Domain, and he did not go to the depths of the Heavenly Fire Domain.

In a total of three months, Bai Leng Ye discovered many kinds of heavenly fires. But there's only one kind of absorption.

The remaining heavenly fires are either too small, or their attributes are very weird, and there is also a kind of heavenly fire, which itself is actually poisonous, if Bai Leng Ye absorbs it, the toxicity will be on his body, and no one can approach him at that time.

However, in the past three months, he has not been absorbed, at least his strength has improved again, and he has reached the fifth level of the Cave Void, and he is not far from the sixth level of the Cave Void, and it will only take about two months.

On this day, the temperature of the sun was a little high, and the height was terrible, even the air was distorted, the heat was barbecuing the earth, and the ground was drying up little by little.

In a desert, Bai Lengye and Mu Yanran walked in it, step by step, but not long after, the footprints behind them would be buried by mud and sand.

It had been seven or eight days since they had come to this place, and in the past seven or eight days, Bai Leng Ye was about to turn around this desert.

But he hadn't found the desert fire he needed yet, which made Bai Lengye unwilling, so he continued to look for it.

The reason why he knew that there was this kind of fire here was that he overheard it, thousands of years ago this place was originally a lake, but because of the appearance of the heavenly fire, the lake evaporated and dried up, and then over time, it became a desert.

Many people have come from afar to look for it, but the fire seems to have disappeared that day, and no one can find it at all.

Now, Bai Lengye is just like those people, he wants to find that kind of heavenly fire here, this kind of flame that has been born for a thousand years must be very powerful, and if he absorbs it, maybe his strength will increase by leaps and bounds.

Call......

A gust of wind blew, and countless sandy soil flew up all over the sky, and Bai Leng Ye closed his eyes, turned his back to the wind, and continued to walk backwards and forward.

Bang!

Suddenly, a huge stone hit his back, Bai Lengye snorted, and only stopped after sliding under his feet for nearly a few dozen meters.

"Husband, you're fine. Mu Yanran hurriedly ran over and asked.

"It's okay, it's just a stone, how can it be ......"

"Pounce. ”

Bai Leng Ye suddenly spurted blood, and he lowered his head in disbelief, seeing that his ribs had been pierced, and a sharp stone had pierced into his back.

Mu Yanran exclaimed, she grabbed the stone and wanted to pull it out, Bai Lengye grabbed the other party's wrist and shook her head.

"I'll just do it myself. ”

Bai Leng Ye's face was pale, he clenched his teeth, and pulled out the stone with little bit of force.

The blood stained his whole body, and after taking out the medicinal powder and touching it, the blood slowly stopped.

"How could a stone, break your defenses and seriously injure you. Mu Yanran said in shock.

Bai Lengye shook his head, he looked back at the stone that hit him, the other party had nothing to do, lying quietly in the desert.

After a while, Bai Lengye walked up to the stone and tapped it with his hand.

"This, this is not a stone, but a top-level material for refining magic weapons!" Bai Lengye said in amazement.

Mu Yanran nodded as if she didn't understand.

"No wonder, this material must have been thrown somewhere, the hard part of this thing, coupled with its super speed, is equivalent to a high-speed moving flying sword stabbing at it. ”

Speaking of this, Bai Lengye's eyes looked in the direction where the stone was flying, and his eyes gradually showed a look of joy.

"I know, there must be traces of Heavenly Fire there, and this refining material is the best proof of this. ”

"Let's go and see. ”

Bai Lengye put away the iron stone, and then walked forward with Mu Yanran.

The two of them came to a huge pit, and when they stood in it, they could not feel the presence of the wind and the yellow sand, and it seemed that everything was quiet here.

Bai Lengye squatted down and gently stroked the deep pit with his hand, as if the iron stone flew out of it just now.

But the iron stone weighed at least a thousand kilograms, and how much wind it had to blow it up made Bai Lengye very puzzled.

"Old, husband, look there. Mu Yanran pointed ahead.

Bai Leng Ye looked at it, and countless white lights flew into the sky in the distance, and as the distance gradually narrowed, Bai Leng Ye's pupils shrank sharply.

The pagoda flew out of his hand, and Bai Lengye flew in with Mu Yanran, that is, when the pagoda had just landed, the hundreds of millions of terrifying flying knives had already arrived.

Those flying knives are very terrifying, each of the upper forces definitely has the full force of the Yuanying master, there are at least hundreds of thousands of dense Dao, if he hid late just now, it is equivalent to being besieged by hundreds of thousands of Yuanying masters, then he will not be able to die anymore.

By the time the flying knives passed, the desert in place had long been destroyed, and at this time, Bai Lengye finally knew how the iron stone flew over, and it must have been these flying knives that kept hitting it and throwing the iron stone away.

"Husband, you see it's here again. Mu Yanran said in a condensed voice.

Bai Leng Ye looked intently and saw that in the distant sky, countless wind blades flew in, each of these wind blades was the size of a building, and after they landed on the desert, they would directly split the desert into cracks hundreds of meters long.

Bang bang!

Bai Lengye clearly felt that the Tower of Babel was shaking a little, and the sound of metal collision kept coming out, that feeling, as if this Tower of Babel couldn't resist those wind blades.

Bai Lengye was a little nervous in his heart, if this Babel Tower couldn't resist it, then the two of them would go out, and I was afraid that they would be torn apart by these wind blades in an instant.

But apparently his worries were unnecessary, and the wind blades came and went as fast as they came, and after a minute, they all disappeared at the end.

"It's scary, what the hell is this place. Bai Lengye asked with some trepidation.

The two of them left the Tower of Babel and saw that the scene outside had completely changed, the original pit had been flattened, and there was an endless desert all around, and there were large cracks.

Knowing that there might be some danger ahead, but Bai Lengye still had to go over and take a look, maybe what he was looking for was there, wouldn't it be a pity to give up like this.

The two of them walked forward very carefully this time, sometimes when they encountered a sandstorm, Bai Leng Ye would also hide in the Tower of Babel, because he was not sure if there would be something hidden in the sandstorm before, and when his head was cut off, it would really be dead.

Half a day later, Bai Lengye finally came to the deepest part of the desert, and here, he saw many demon beasts and human corpses.

The bones looked very old, as if they had been around for a while, and some of them had been bitten out of the bones by insects.

"Yanran, be careful, there may be some monsters hiding here. ”

"Hmm. Mu Yanran nodded, and then condensed an ice shield to follow, carefully following behind Bai Lengye.

There was a steep slope in front of Bai Leng Ye, and Bai Leng Ye wanted to climb up, but after Zi Ah stepped out with one of his feet, the sand seemed to have a suction force, sucking his foot down little by little.

Bai Leng Ye wanted to fly, but he found that the power of flying did not work, and most of his legs had been caught.

At the moment of emergency, Mu Yanran grabbed Bai Lengye's shoulders and jumped hard, and the two left the place.

Bai Lengye stared at the steep slope in front of him, and he kicked a stone over, and the stone plopped and was swallowed directly by the desert.

"It's funny, even the desert has turned into a monster. ”

Bai Lengye smiled and said, "What kind of monster are you, don't you show up quickly, what is sneaky." ”

The steep slope suddenly moved, and something like a mouth opened, and then there was a powerful tearing force, and the two of them were caught off guard and were directly sucked in.

Bang!

The two fell from the sky, and Bai Lengye hurriedly stood up, only to find that he had come to a secret passage.

"It's okay. Mu Yanran asked.

"I'm fine, but we may actually be in a place where treasure is hidden. Bai Leng Ye smacked his lips and said.

Mu Yanran glanced around, this I secret passage looks very long, and there are many traces left by axes around it, it seems that someone wants to go out, but in the end they didn't get out here.

The two of them held hands and walked cautiously forward, and they could see different marks on the walls around them, all of which were chopped by some weapons.

On the ground, there were also some corpses, and the armor and clothing looked very ancient, and they were all weathered and could not see their original appearance.

"The Strongest Sword King ......"

Bai Lengye saw the inscription on the ground, and then looked at the pile of white bones, he couldn't imagine that this guy would actually be the strongest sword king.

It is rumored that thousands of years ago, the strongest sword king was born, and with extremely powerful means, he destroyed several major factions at that time, and his name was unmatched.

But then the other party disappeared, and the bones were found by Bai Lengye today, and it turned out that he died here.

"That's the strongest boxing god. ”

"I'll see. ”

Bai Lengye walked up to a skull head, and there was a line of blood on the ground, left by the strongest fist god.

The strongest boxing god, and also a super master who swept the cultivation realm thousands of years ago, it is rumored that his strength has surpassed the out-of-body and reached another height.

Unexpectedly, the other party also died here.

The two continued to walk forward, and along the way they saw many dead people, most of them masters who had already made a name for themselves thousands of years ago.

Not long after, the two of them seemed to have come to an end, and there was only a large black iron gate in front of them, exuding the smell of desolation.

And there are still a few lines of blood on the big iron door, even if the age is a long time ago, but the bright appearance looks like it has just been engraved.

"Break the iron door and you will become an immortal!"

"If you break the truth, you will be an immortal, an immortal will not be old or immortal, and an immortal will be eternal and immortal!"

These lines of blood are written very deeply, and they have not been erased to this day.

"Could it be that there is a secret of becoming an immortal behind this iron gate?" Mu Yanran said in a daze.

"How is it possible, even if it is an immortal, it is also a flying immortal, how can it be that the secret of becoming an immortal will be here. ”

Bai Lengye shook his head and said.

"Then what does it mean, isn't it true that so many people are dying here to open this door and obtain the secret of becoming an immortal?" Mu Yanran asked curiously.

Bai Lengye pondered, but he thought about it for a long time and a half day, and he couldn't figure out what this was, he knew that becoming an immortal was to ascend to the immortal realm, and he would never say that he was in this iron gate.

If there is any treasure in it, he still believes it, but this immortal ...... He really didn't believe it.

"Shall we open this iron door and see? Mu Yanran asked.

Bai Leng Ye Nunu mouthed and said: "You can see if you look at the people behind you, so many super masters have died here, but none of them have opened this iron gate. ”

"And have you noticed that there is not even a trace of damage on this iron door, except for the indelible blood characters?"

Mu Yanran nodded, she had just found out.

"The rocks around all around have traces of being attacked by weapons, but this big iron gate is not, which shows that this iron gate is probably really indestructible, these super masters did not break this iron gate together, and finally were trapped here to death. ”

Mu Yanran's face changed, and she said, "Then we can't get out." ”

Bai Lengye groaned, he knocked on the iron door with his hand, there was no sound, I don't know what material it was made of.

"You dodge, let me attack. ”
