Although there was no sea of fire from the true fire of the sun, the magma still rumbled and echoed in this huge underground cavern. Like the low roar of a giant beast.

Dongfang Ziyan stood in front of the Red Emperor Charm, staring at this sword without moving, feeling the ancient power that had been silent for a long time, after more than three hundred years, the smell of blood on this sword still seemed to linger.

But this Sword Emperor has been wrapped in volcanic ash, and the luster of the past is gone, perhaps for hundreds of years, this spiritual artifact has been waiting for its master to take him away.

Dongfang Ziyan stretched out his right hand and stretched out it towards the Red Emperor Charm, but the invisible force bounced his hand back, shaking his right hand numb. He looked up, only to see that the Red Emperor's whole body had appeared more than a dozen iron chains at some point, the iron chains were connected to the top of the cave, and there was an iron lock on the sword body, and the iron chain and iron lock were refined black iron.

In the field of alchemy machinery, metal is the most important material (swords in alchemy, mechanical transformation of guns and weapons in machinery must be made of metal as the main material), and among the metal elements, iron is an indispensable element. The iron element is hidden in the ore, so there is the forging technology of alchemy machinery (alchemy forges iron ore for initial processing, and machinery carries out further transformation and processing, which is the general difference between alchemy and machinery). The forged iron is divided into three types: mortal iron, iron and black iron, and only the master of alchemy machinery has the ability to forge the black iron, because the black iron is called "indestructible metal", and the physical attack and elemental attack are basically ineffective against it, even if the metal monk wants to decompose the black iron particles, it also requires a high level of cultivation to do it.

Eighteen dark iron chains and a large black iron lock, this is the last binding of the artifact, if Dongfang Ziyan wants to obtain the artifact, it is impossible to pull all the iron chains out of the rock wall, because the iron chains are connected to the load-bearing rock wall, and easily pulling the iron chains will cause the collapse of this underground cave.

Dongfang Ziyan swallowed, he was thinking about how to start. His hand groped in the sac, and suddenly he pulled out the remnant of the Fire Sword. It's been almost three years since he used this alchemy weapon, and it's really a little distressing to be destroyed by Suzaku.

Suddenly, he had an idea, although the Fire Sword was only made of iron, he always felt that the Fire Sword could help him open the big black iron lock that locked the Red Emperor.

There is a lock hole at the bottom of the big black iron lock, how can a real mechanical lock have a lock hole? And the shape of the keyhole is similar to the horizontal cut of the sword, Ziyan is familiar with the inertia of mechanical instruments, if the Xuantie lock has a keyhole, then there will be a brow. Dongfang Ziyan immediately made a decision, inserted the Fire Remnant Sword into the keyhole, his right hand was quickly covered by the machinery, the mechanical arm completely wrapped the lock, and after a few metal buzzes, the Fire Remnant Sword actually matched the keyhole completely!

The crisp sound of unlocking sounded, Ziyan's mechanical arm slowly loosened, and the dark iron lock suddenly showed golden lines, only to hear a cracking sound, and the dark iron lock fell to the ground!!

The black iron chains bound by the Red Emperor's body were all loosened, and the ancient sword fell to the ground, inserted into the stone ground, and at the same time, the covering shell caused by the volcanic ash shattered, and the true face of the Red Emperor appeared.

Dongfang Ziyan pulled out the Red Emperor with one hand, the Red Emperor's whole body was dark gold, the slender sword god was seven feet long, it was a common type of straight long sword, from the hilt of the sword to the tip of the sword was an engraved ancient incantation, and the weight was estimated to be twenty kilograms.

"Legend has it that among the thirteen artifacts, the Red Emperor Charm ranks second, and the Shadow Demon Sword, the Huangquan Tiandu Sword, the Flying Ghost Halberd, and the Weeping Blood Glass Sword are all made of the Nine Heavens Meteorite, this natural power is really shocking......" Ziyan held the Red Emperor, and a primordial power spread out.

"Hehe, finally succeeded." Dongfang Ziyan wiped the sweat from his head.

An earth-shattering loud bang sounded, countless gravel splits fell, and Ziyan's newly relaxed heart came up again, "What's the matter...... he rushed down on the stone platform with an arrow step, it may be that without the support of the Red Emperor, this underground cave is about to collapse!!

"Damn it!" Dongfang Ziyan held the sword in his right hand and blocked his eyes with his left hand to prevent the rubble from splashing into his eyes, and a boulder fell with a bang, and this cave trembled everywhere!

There is still about a quarter of an hour away from the exit, Dongfang Ziyan's own physical strength has been overdrawn, and it is difficult to maintain even a fast run, it is only a matter of time before this cave completely collapses, once he can't escape, he will definitely die!

[I don't even leave the last way to live...... What a terrible fortification!! When Dongfang Ziyan tried to run towards the exit, countless falling rocks fell from the top of his head......

Dongfang Ziyan's hands and feet were weak, and his pupils contracted violently.

Nine Heavens Pillar of Thor!!

Hearing a loud roar, eighteen giant pillars of thunder and lightning rose from the ground, knocking the rubble apart and holding the top that was about to collapse. The man who was rescued by Ziyan came back again, he was expressionless, grabbed the dying Dongfang Ziyan, and rushed out of here quickly.

The man escaped with Ziyan, and the two stopped at the passage in the crater. Ziyan gasped for breath and listened to the loud noise of the underground cavern below, which completely collapsed.

"You...... How did you come back again. Ziyan asked breathlessly.

"I don't like to owe others, Dongfang Ziyan, right, you saved me, I owe you." The man said.

Dongfang Ziyan was covered in injuries, and this situation had happened many times. "It seems that good people really have good rewards, alas, for the first time."

"Have you seen the Eastern Emperor?" the man asked, sitting beside him.

"I met a man in one of the tunnels of this volcano, but he's dead." Dongfang Ziyan said, "But he seems to have died after meeting me." ”

"yes...... It's good that Dongdi can persist for these thirteen years. The man said silently.

"Do you know each other? By the way, I don't know your name yet. Dongfang Ziyan asked.

The man looked at him, was silent for a while, and said, "I escaped from the valley with the Eastern Emperor Samael Shalon, my name is ...... Rhein Gruss. ”

[Rhein Gruss ......], Ziyan seems to have heard of this name, which is a Falouis name.

"Maybe you don't know me, because I've been out of the public eye for thirteen years." Rhine smiled lightly. "Thirteen years ago, I committed a heinous crime in the Divine Realm, which is why I was wanted by the River Basin."

"Oh, it doesn't matter, anyway, in my eyes, you are a good person, and it is a pleasure to meet you, Uncle Rhein." Dongfang Ziyan was indeed a little hesitant in his heart, especially when Rhine said that he had committed a heinous crime.

Rhine was stunned for a moment, "Aren't you afraid that I will hurt you, don't you think I'm a vicious person?" ”

"No, I think my uncle is a very good person." Dongfang Ziyan said with a smile, "Without an uncle, I'm afraid I would have died underground just now." Ziyan paused, "But, uncle, didn't you escape from the river basin, why are you trapped here?" ”

In the dark corridor, suddenly only the breathing of two people remained. Rhine was silent for a long time, and he muttered, "It's complicated, I can't tell you clearly now, this matter and my previous wanted by the river basin are all related to the 'Hundred Years of Chaos', by the way, your name is Dongfang Ziyan?" You are a member of the Oriental family. ”

Dongfang Ziyan was stunned, "Yes." ”

"Now, the Red Emperor is yours, where are you going next?" Rhein asked.

"Go to the Demon Realm, my companion is still waiting for me at the top of the mountain, I must hurry back." Dongfang Ziyan said.

"With your current state, you probably won't even be able to pass the gatekeeper's level, so I'll help you go." Rhein said and held out his hand.

Dongfang Ziyan smiled, he held Rhine's hand, and was pulled up by Rhine, "Uncle, I remember who you are, 'King of the Day' Rhein Grus!" Famous in the Three Realms! ”

Volcanic top

The nameless yin wind blew, the Dragon Emperor stood not far from the sloppy monster, and the Suzaku was still sitting, but the ground had been destroyed, and black smoke was rising from the deep ditches and huge pits, and there had just been a little commotion here, but just a little commotion had caused such serious consequences.

"Lingxu, I don't want to clash with you head-on yet, let's go back to your hut when you've had enough!" Suzaku snapped.

"You didn't say a word when I fought Fenrir just now, how can you speak now?" The man known as "Spirit Void" asked with a smile.

"You go and take care of your boundary gate, I take care of my artifact, and none of us will offend anyone." Suzaku closed his eyes.

The Dragon Emperor protected Yan Wei behind him, and even he didn't know how far things would go. The sloppy man in front of him is the gatekeeper of the Demon Realm Crossing Gate, and almost no one knows his name, but every year many monks are defeated by him when they try to approach the Boundary Crossing Gate. This is a mysterious man, his strength is unfathomable, no one knows whether he is a black stone demon or a human, and almost no one knows when he started guarding the gate here.

"Have you listened to me? I didn't say that I was here to find fault today, I came to tell you something, it was about... The contract master of the dragon royal. The man held out his finger and said.

"What? What the hell are you doing. The Dragon Emperor was furious.

Suzaku's brows furrowed, his face sank, he knew that this man was a master of the overall situation, although he did not go out of the North Pole all year round, and even his own cabin was not far away, but he could always know the major events in the world.

"It's about the foresight of the 'Flame Demon', because of some fortuitous events. Your master, yours, is probably dying. After the man finished coldly, it seemed that the whole world was silent.
