"Paving the way?"

Gu Yige stared at the shoulder pads in surprise, this shoulder pads were made from paving materials. Although the metal of the Dark Metal Hell is everywhere, it is too extravagant to use black iron to pave the way.

When Han Yue saw Gu Yige pretending, she thought she was deliberately teasing her, and she was even more angry.

"What can you do if you don't use it to pave the road! Whether it is a soldier or a battle armor, the requirements for metal materials are first of all hardness, toughness and plasticity. Needless to say, toughness requires that metal materials must be elastic and can change shape, otherwise the soldiers can only maintain one form, then they are not soldiers but ordinary weapons. Plasticity is the most important point, soldiers should be integrated into multiple properties of materials, can increase weight, improve destructive power, with some special properties, which requires metal materials must be able to fuse with other metals, and the more metal fused, the better. ”

"In addition to being hard, black iron has neither toughness nor can change its form. It is not malleable, and it cannot be fused with other metals. So what's the use of just being hard, there are too many metals that are both hard and have toughness and plasticity to replace black iron, who would use this dead metal. Therefore, black iron can only be used to pave the ground. ”

Gu Yige listened to Han Yue's words, and realized that black iron was such a metal material, so the shoulder guards made from it were also a garbage soldier.

"Did I really get it wrong? ”

Han Yue calmed down her anger and said, "Okay, now let's get to know each other officially, my name is Han Yue, the warden of the Seventh Prison Hunting Prison, and a Flesh Sixfold Martial Artist. ”

Gu Yige was a little surprised, you must know that the warden is a powerful person in a prison, especially the warden of the hunting prison is extremely powerful. Unexpectedly, this young woman turned out to be the warden of the hunting prison in the seventh prison, no wonder it was not a good idea to take out a king soldier core casually.

"I am Gu Yige, a member of the First Hunting Team of the Third Prison, and my cultivation is a fourfold body. ”

Han Yue nodded and said, "I know you." ”

Gu Yige was stunned for a moment and said: "When you were on the cliff just now, you also said such a thing, you said that you saw me when I first came. ”

"Well, at that time, I went to your third prison and talked to your mine warden Gao Feng about joint hunting. It was at that time that you came here from the outside world, and I met you at that time. ”

Gu Yige heard Han Yue mention Gao Feng, and was puzzled: "I heard that the prison director must be a martial artist with a six-fold body in the flesh, so why is Gao Feng only a five-fold body, but he is the warden of the mine prison." ”

"Gao Feng is an exception, his identity is very mysterious, I don't know much, but his status in the third prison is very special, so that he can become the warden of the mine prison with a five-fold cultivation of the flesh. ”

"Alright, let's go to the cave first and see if there is any other way out. After Han Yue finished speaking, she turned around and walked towards the cave.

Gu Yige followed behind Han Yue and walked towards the cave. The cave was deep and dark, and it was not clear where it leads. As he walked, Gu Yige lowered his head and thought about the reason for the changes in his body.

"The change of the body starts with getting the black iron in the mountain of metal garbage. First, the body was attacked by black iron, and then after coming to the Dark Metal Prison, the dantian and meridians were repaired, and the muscles, organs, and bones became very powerful, and the strength was much higher than that of the martial artists of the same realm.

All this changes start with getting the black iron block.

Thinking of this, Gu Yige finally understood the reason for the changes in his body, and also knew why his bones could not recover.

"The root of all this is on the black iron, and the black iron must have some kind of connection with his body, making his body stronger, different from ordinary martial artists. Then his bone injury and his inability to heal like an ordinary martial artist should also be related to black iron. ”

As long as the reason is understood, then a solution can be found, and everything must be solved from the top of the black iron.

Gu Yige looked at the dark environment around him, this place is dangerous and unknown, and now his body can't enter the state of black iron, and his strength is greatly reduced, so it's best to have a few more hole cards to save his life.

Thinking of this, he took out the shoulder pads from his arms and examined them carefully, the outside of the shoulder pads was in the shape of tiger claws, and the inside was a metal clip ring. In order to wear this shoulder brace on the shoulder, the metal snap ring inside must be fastened one by one to each muscle of the shoulder.

Gu Yige's right arm was originally wearing an arm guard, wrapping his fist and entire arm in it. Now after wearing the shoulder pad, the entire right arm and right shoulder are wrapped in metal, and this shoulder guard is in the shape of a tiger's claw, and the five sharp claws are just buckled on top of the armguard, and it is tightly fitted.

When he was on the cliff at that time, he saw that the ink ghost flying fish had this shoulder guard on it, although he only glanced at it, but he was sure that the shoulder guard and arm guard were a set, so he desperately grabbed it.

It's just that whether it is Zhang Dahai or Han Yue, the evaluation of the arm guards and shoulder pads is that there are no other advantages except for hardness.

It can't fuse other attribute metals, it has no plasticity, it's not a product, it's a low-level soldier, maybe it's not even a soldier and it's just an ordinary weapon.

The fish scale arm guard can cut through the body of the golden giant bear because of the extremely fast vibration of the ancient one grid muscle, so that the scales on the arm guard also vibrate extremely quickly, producing a strong sharp and cutting effect, so that the body of the beast can be easily cut.

Although the fish scale arm guard is sharp, it really only shows the characteristics of hardness. If it weren't for the control of the ancient style, it could indeed only be regarded as a non-consuming weapon.

However, Gu Yige always felt that these two soldiers should not be so ordinary. Moreover, there are two or one sets of soldiers like fish scale arm guards and tiger claw shoulder guards, and he always feels that it shouldn't be so simple.

The two walked all the way, Han Yue walked in front, and Gu Yige followed behind and bowed his head to think about the problem.

Gradually, the temperature around me became higher and higher, and the hot wind blew on my face.

Suddenly, Han Yue, who was walking in front, stopped his body suddenly, and Gu Yige was looking down to think about the problem, and bumped into it.

Han Yue felt a strong aura from behind her, and frowned, "What are you doing?"

Gu Yige touched his chest, feeling as if he had hit an iron block: "Why did you stop suddenly, and your body is so hard, it hurts me so much." ”

"Bastard, if you dare to talk nonsense again, believe it or not, I'll beat you. Han Yue waved her fist and said angrily.

Han Yue's body became relatively hard because of the special exercises she practiced. Although she is a martial artist and is informal on weekdays, she is still a woman after all, and she was hit by a man, and said that she was hard, how could she not be annoyed.

Gu Yige shaved his face, and he didn't know why women always like to be mad.

Han Yue glanced at Gu Yige and said, "Don't you feel that it's getting hotter and hotter here?" ”

Gu Yige nodded and said, "Actually, when I was outside the cave, I found that this mountain range was hotter than other places, I don't know why. ”

Han Yue's eyes flickered, as if she had thought of something, and she quickened her pace and walked forward.

The two of them turned a corner, and suddenly their eyes lit up, and the cave came to an end, and a sea of magma lay in front of them.

The boiling magma kept tumbling, and the rolling heat wave hit the face, reflecting the surrounding area in a fiery red.

Gu Yige looked around and saw that they had passed through the cave to the inside of the mountain. But there was no road ahead, only a sea of magma in front of them.

Han Yue stared at the sea of magma in front of her and said excitedly: "Sure enough, it's here, I didn't expect the entrance to be under the cliff, so I have been looking for it for so long." ”

Gu Yige looked at Han Yue and asked, "Do you know what kind of place this is?"

Han Yue nodded and said, "When you were in the third prison, did you hear anything about the fire. ”

Hearing Han Yue mention the furnace fire, Gu Yige suddenly remembered that when they had a conflict with Sun Xiong, Sun Xiong and Zhang Dahai had both mentioned the issue of the furnace fire.

Gu Yige felt the heat rushing to his face, and said: "I don't know much about the problem of the furnace fire, I heard that in the seven prisons of the Dark Metal Prison, the purifiers all use the furnace fire, and the furnace fire seems to be controlled by the first prison, which can cut off the furnace fire of the other prisons. ”

"That's right, this is the fire in the first hell, and it's also the source of the fire in the other six. Han Yue stared at the sea of magma and said with burning eyes.

Gu Yige glared and said in surprise: "You said that this is the furnace fire of the first prison, then isn't this the first prison!"

The first prison and the third prison are far apart, and he was chased by the ink ghost flying fish for seven days and seven nights, and he actually chased him to the first prison.

Looking at the rolling magma and feeling the hot air coming to my face, I don't know why, I feel very comfortable in my body, and the pain caused by bone cracks has been reduced a little.

Gu Yige stared at the magma sea in front of him and said, "This magma sea is the furnace fire, so how did this magma flow to the other six hells. And where did the magma in the first prison come from, can't we find its source and prevent the first prison from controlling the fires in the other prisons? ”

Han Yue stared at the sea of magma, and said with a complicated look in her eyes: "I can answer your first question, the magma of the first prison leads to the other prisons through the veins under the dark metal prison, if the first prison cuts off the entrance to their side, then there will be no magma at the exit of the other prisons." Of course, this kind of heart-breaking thing is very serious, and once it happens, it will be a war between prisons and prisons. ”

"As for the second question, I can't answer you, and no one can answer you. Because no one knows where the source of the magma sea is?"

Gu Yige was stunned for a moment and asked, "Why doesn't anyone know, as long as you follow the direction of the magma sea and look all the way, won't you be able to find the source?"

Han Yue shook her head, a trace of inexplicable emotion flashed in her eyes: "The truth is so, but no one can follow the direction of the magma flow and get to its source. ”

After Han Yue finished speaking, she looked at the magma sea silently, her eyes flickering, and she didn't know what she was thinking.

Gu Yige looked at the magma sea in front of him, and said secretly in his heart: "It turns out that the furnace fire used by the Seven Hells to refine the soldiers is the magma here. I just don't know why I have to use the magma here as a fire, is there anything special about this magma?"

Suddenly, Han Yue pointed to the magma sea in the distance and said, "Look, there is a metal bridge there. ”

Gu Yige looked in the direction of Han Yue's finger, and sure enough, he found an arched metal bridge in the magma sea. The metal bridge was huge, spanning the magma sea, with one end on the side of the ancient two and the other end across the entire sea, and it was unknown where it led.
