Over time, the cold and hot energy in the entire metal pool is completely absorbed by the ancient organs.

Because the cold and heat energy decreased, the prisoners no longer felt the pain, so they stopped cursing, and began to slowly close their eyes and rest after a tiring day.

When Gu Yige opened his eyes, he found that the liquid energy in the entire metal pool had been completely absorbed by him, and the strength of the organs had actually increased a little more than before, and the internal strength had also increased by a hundred catties.

"I can't imagine that the strength and internal strength of the organs can be strengthened and improved in this way. After that, it is possible to cultivate by absorbing the energy in the metal. However, I have never heard of this cultivation method, could it be because of the changes in my body that I can absorb the energy in the metal liquid!"

While Gu Yige was guessing in his heart, he was also pleasantly surprised.

Although the strength of one hundred catties is insignificant compared to the internal strength of ten thousand catties. However, it is very difficult to increase the strength at the limit even when the physical strength is saturated.

And by absorbing the energy in the metal liquid, he found a new way to increase his strength.

In fact, Gu Yige didn't know that the reason why he was able to absorb the energy in the metal was because he had black iron particles in his body.

The characteristic of black iron is that it can absorb and invade other metals, so when the cold and hot energy in the metal pool enters Gu Yige's body, he happens to use his internal energy, so that the subtle particles in his body, including the black iron particles, work together. Naturally, the black iron particles begin to absorb the cold and hot energy in the metal pool, transforming it into strength and strength in the body.

But it is not easy to improve the strength in this way.

The liquid in the metal pool belongs to the five elements of metal, with the energy of water and fire, and such metals are very rare even in this place.

If he wants to improve his strength in this way, the amount and value of precious metals he needs will be very large.

It can also be seen from this that the energy of a pool of metal liquid can only increase the strength of one hundred catties. And the black iron block can repair and upgrade the organs of the ancient grid to 10,000 catties.

It can be seen how powerful the energy contained in black iron is, and it can also be seen how precious black iron is.

Although this method of increasing strength is difficult, Gu Yige has at least found a way to increase his strength.

The black-faced man Gao Feng originally wanted to use the cold and hot energy in the metal pool at the poles to teach Gu Yige a lesson. There is not a single person who has been locked up here for the night, and after going out, there is not a single one who is not obedient.

Not only did it not have any effect, but it also helped Gu Yige improve his strength and let him find a way to control his body.

Gu Yige's eyesight also adjusted to the darkness at this time, and the situation in the metal pool slowly became clearer. The metal pool was the size of a hundred zhang and filled with metal liquid, and was surrounded by a solid metal wall that kept everyone inside.

was observing the surrounding situation, and suddenly a low voice came from his ear: "What is the little brother thinking?"

Gu Yige turned his head and saw two people coming over beside him, one was a white-faced scholar, and the other was a gray-clothed man.

Gu Yige looked at the two of them and wondered, "Who are the two?"

"Below, Li Zi'an. The white-faced scholar clenched his fists and said, then pointed at the man in gray: "This is Liu Cheng, and both of us are from the Moon Shadow Kingdom." ”

"Moon Shadow Country?" Gu Yige frowned slightly, not knowing what kind of country this was.

Li Zi'an was stunned for a moment, and said suspiciously: "Little brother doesn't know about the Moon Shadow Country?"

"I don't know. Gu Yige recalled that after he fell from the metal ship, he fainted. By the time I opened my eyes again, I had already arrived at the Dark Metal Prison, and I really didn't know what the Moon Shadow Country was.

Seeing that Gu Yige didn't look like a fake, Liu Yan moved in his heart and asked, "So the little brother doesn't know what kind of place this is?"

Gu Yige nodded and said, "I only know that this place is called the Dark Metal Prison, or I know it from that gossip mouth, and I don't know anything else." ”

Li Zi'an and Liu Cheng glanced at each other, they were both shrewd people, and judging from Gu Yige's expression, he was not lying. I wondered if this young man was not someone sent by a certain force.

Liu Cheng leaned over to Gu Yige and said, "Since the little brother doesn't know what kind of place this is, how did he come here?"

Gu Yige said: "I was seriously injured and comatose some time ago, and when I woke up, I came here, and I really don't know how I got here. ”

Li Zi'an glanced at Gu Yige and said, "Since the little brother doesn't know the situation here, then I'll tell you about the situation in the Dark Metal Prison." ”

Gu Yige nodded and said, "Please also advise." ”

Li Zi'an's deep voice sounded in Gu Yige's ears.

"The Nine Heavens Continent where we are located is a big world, and there are many small worlds in the big world. The environment and resources of the small world are good and bad compared to the big world, but there is one thing in common, that is, the warriors can freely travel between the big and small worlds. ”

"The Dark Metal Hell is a small world, and its entrance is in the Moon Shadow Country, controlled by the five major forces of the Eastern Kingdoms. But this place is different from other small worlds, this place can only enter but not exit, like a prison, trapping the people here firmly inside. ”

"This place is different from the outside world, there is no heaven and earth aura here, and martial artists can only cultivate to the ninth level of the flesh. Whether you were originally a powerhouse of the Qi Condensation Realm or a martial artist with a triple body body, you could only reach the strength of the ninth level of the flesh body when you came here. ”

In other words, the strongest person in this world is the Ninefold Flesh. ”

"Because he can only enter and not go out, he is used as a prison by the five major forces, imprisoning their enemies and internal opponents. This is where the word 'prison' in Dark Metal Prison comes from. ”

Gu Yige frowned slightly when he heard that the Dark Metal Prison could only enter and not exit: "Why can we only enter and not exit, and we can't go out from the entrance?"

"Little brother, have you forgotten where the entrance was when we came?"

Gu Yige suddenly thought of the scene he saw when he opened his eyes. A black vortex appeared in the sky, and it was from that vortex that they came to the metal prison.

"You mean, that black vortex that appears in the sky is the entrance, and the only exit. ”

Li Zi'an scooped up a handful of the metal liquid around him with his hand and said, "Yes, we were all thrown into a pool of metal liquid and slowly sank to the bottom. And through the bottom of the pool, you will come to the dark metal hell. So the bottom of that metal pool is connected to the sky on this side. The entrance is in heaven, and the exit is in heaven. ”

Gu Yige took a breath of cold air: "The exit is in the sky, so how can I get out of here." ”

Li Zi'an continued: "Martial artists in the flesh realm can't fly. Even a martial artist in the Qi Condensation Realm, or a higher realm, could not fly to the sky. So this is a prison, and it is also a Jedi full of dangers, without the aura of heaven and earth. ”

Gu Yige looked at Li Zi'an silently, digesting the news he said, and couldn't believe it in his heart: "How can there be such a place, without the aura of heaven and earth, martial artists cannot cultivate to the condensation realm, and the exit is in the sky, is this really a natural cage." ”

Gu Yige was silent for a moment and asked, "What does the 'dark metal' in the Dark Metal Prison mean?"

This time, it was Liu Cheng who answered his question: "The darkness is because the sky here is always dim, there is no light, no hope can be seen, and people can only live a desperate life in the dark." ”

"And metal, because it's almost everywhere there, and we've seen it when we came, and the cities here are made of metal. Even the ground is paved with fine iron, which is an indispensable material for building soldiers when taken outside, but here it can only be paved, so you can imagine how much metal there is. ”

"As for the more precious metals, there are also abundant reserves here, and they are worth a fortune if you take them out. ”

Liu Yuan's voice was a little deep: "The sky here is always dark, except for metal, there are no other resources, and it is a natural cage." That's why it's called the Dark Metal Hell. ”

After listening to the introduction of the two, Gu Yige slowly understood what kind of place he was in.

"Could it be that I can only be trapped here for the rest of my life, what about the blood feud in the mine, what about Sister Su. ”

"No, there must be a way to get out, even if it is a prison, there is no prison in this world that cannot be escaped. ”

Gu Yige's simple, direct personality makes him sometimes do some oolong things. But the seriousness and persistence of his character make him not give up once he has decided on his goal.

Gu Yige's gaze slowly swept over the dungeon, and suddenly he found that there were originally more than a hundred prisoners, but now there were only more than fifty people in the metal pool, where did the rest go?
