Of course, poor Gu Yi didn't know what the Dao was丨Taijiao丨Dahao, he just felt that the terrible smell of sweat diffused from the old man's armpits was about to smoke him and faint

In order to break free from the other party's clamps, Gu Yi was stunned and almost broke all the green tendons, originally thinking that his strength in the ninth order of the Karma Pin, although it was not super strong, but with the strange ability of the previous body, it must not be regarded as weak.

But now that he was clamped by the old man's arm, he couldn't move at all, and Gu Yi, who had finally developed a little self-confidence, was broken, and at the same time he felt a little scared, Nima, the old Tibetan mastiff, shouldn't be the mother?

Before he finished thinking about it, he felt that his body was in the clouds and fog, and before he had time to react, he was thrown on the scorching rock ground by the old dwarf like a toad, and Gu Yi, who was hot at the hot temperature, jumped up with a snort, and hid by a pool of water, feeling that the clothes on his back were on fire, and Gu Yi, whose hard mane was burned, plunged into the pool without hesitation.

As soon as Gu Yi jumped in, he felt that his whole body was as if he had been stabbed by countless steel needles, and even his limbs were numb, and his blood was frozen by ice, and he couldn't even struggle and sank like a stone

Just when Gu Yi's thinking began to stiffen, thinking that he was going to die, a long tong reached in, pinched his waist precisely but roughly, lifted him up violently, and threw him on the hot rock ground again.

Gu Yi, who was already covered with a layer of ice skin, fell to the ground with a hard erection, but felt that the hot ground was too comfortable, and it took a while to barely recover his strength, but he shrunk into a ball with a pendulum

The old man laughed a few times, and didn't pay attention to Gu Yi, who was speechless for the time being, and used the tongs to clip out a golden, almost transparent object from the magma pool on the other side, put it on an anvil, picked up his terrible hammer with a huge hammer head, and smashed it violently, and he didn't care if the flying tent sparks splashed on him.

Gu Yi, who was trembling, struggled for a while, but couldn't stand up, so he could only hug his legs and shrink into a ball, twist his stiff neck, and look around sluggishly.

This was the first time he had entered the depths of the fire cave, and when the old man ran in with him just now, he only heard the sound of the wind "whirring", which showed how fast it was, and he didn't know how many meters deeper than the caves he used to ferment wine.

This is a cave in the ground with a considerable space, shaped like an inverted sea bowl, and on the fairly flat ground, it is like a lotus shower, covered with springs of all sizes.

Centered on the strangely shaped workbench where the old man was, half of the spring was churning orange-red boiling magma, and half of the spring was a pool of blue, blue, green, or blue, with different shades of color, calm like mirrors, without the slightest ripple.

What the hell is this place? How can there be such a strange environment? Isn't it said that fire and water are incompatible? How can there be a cold ice fountain and nearly boiling magma in the same cave?

There were no lighting tools in the cave, but it was brightly lit by the orange fire light coming out of the magma pool, and even from the cold pool, colorful cold light shot out from the bottom.

Gu Yi, who felt that his common sense had been subverted again, looked at this strange place in disbelief, in the huge space, a large number of ores, coals, and all kinds of strange iron parts that I don't know what to do with the road, this is obviously the place where the old dwarf with the habit of the bear lives and works all year round.

What surprised Gu Yi the most was that there were so many magma springs burning deep underground, theoretically speaking, a closed high-temperature and anoxic environment should be formed, but here, although the temperature was not low, there was no feeling of stuffiness and heat, but there was not a weak air flow, that is, the wind

Subconsciously looked at the cold pool ice spring on the other side of the magma spring, Gu Yi looked up violently, and saw a small grotto above the cave, where there was a whirring wind, as if a high-pressure air pump was installed inside.

Gu Yi suddenly realized that the cold air in the area of the Cold Pool Ice Spring met the hot air in the area of the Lava Fire Spring, and then it was pumped away by the Eye of the Wind culvert above, and the atmospheric environment formed presented such a strange state

The environment here obviously doesn't look like it's artificially made, Gu Yi was stunned by this kind of nature's magic workmanship, and he didn't expect that there was such a magical place hidden under the hollow valley

Looking at those 丨lava and fire springs丨, Gu Yi couldn't help but think of the 丨earthh丨 in the outer valley, which was also a stable form of lava, and thought that this should be a branch of that earthh.

And those cold pond ice springs丨 made Gu Yi full of confusion, with his "personal experience" just now, the temperature of those springs was at least minus fifty or sixty degrees, otherwise with his physique, he would not have been ossified in an instant, and he was almost frozen.

But the question is, once the temperature of the water drops below zero degrees Celsius, doesn't it solidify and freeze? How can these springs with such a low temperature remain liquid? Is it because it is so pure that it forms so-called "seedless supercooled water"?

Isn't this scientific? Is it possible for such a pure liquid to exist in nature?

Looking at the ground again, the temperature of the place where he is sitting now is not as high as the temperature of the ground near the workbench that the old man threw just now, but it is also fifty or sixty degrees, very hot, and the most strange thing is that the ground here is actually glowing with a layer of metallic luster, as if the whole body is made of metal, and it is as clean as a mirror

Such a closed space, no burning smoke, no dust left by ores, this is all the credit of the eye culvert above that looks like a giant vacuum cleaner and range hood.

After a while, Gu Yi felt that his hands and feet had regained consciousness, although his body was still trembling slightly involuntarily, but he was already able to move, seeing the old man standing in front of the anvil and hammering the metal intently, Gu Yi quietly got up and sneaked towards the exit.

But Gu Yi, who was tiptoeing, had just taken a step when he heard the old man's thunderous voice sound: "Boy, have you slowed down? Want to run? Try out of the hole? Break your legs."

Gu Yi suddenly wilted, turned around and walked towards the old dwarf, no way, this old dwarf's strength is too perverted, with his strength, in the hands of the old dwarf, he is as immature and weak as a chicken chick that has just come out of the shell.

The closer he got to the blacksmith's workbench in the center, the more uncomfortable Gu Yi felt, because the workbench was just surrounded by ice springs and fire fountains, which caused half of Gu Yi's body to be scorched by the high temperature of the fire spring, and half of his body was infected by the cold of the ice spring.

This made Gu Yi very shocked, because with his physique of forging his body to the ninth order, both his resistance and patience have been improved to a very amazing level, and he dare not say that he is not immersed in the cold and heat, but in this cold winter and moon where the snow is flying, he is just wearing such a jade battle suit, and he does not feel any discomfort at all, which shows how high his resistance to cold is.

But here, not to mention the chill after jumping directly into the pool just now, even if he stood far away, it was difficult to resist the high temperature and low cold from both sides, and when he was hesitating whether to turn around and change the sides of his frozen and burnt body to slow down, he suddenly smelled a scorching smell, and when he looked down, the thick-soled combat boots under his feet began to smoke

Gu Yi, who screamed strangely, jumped and fled to the side of the ice fountain with a lower temperature, although he was shivering from the cold, it was better than becoming an iron plate squid, right?

The old man used his long tongs to hold the piece of iron that had become a little dark red, walked to the ice fountain and inserted it into the water, and immediately pulled it back after hearing the sound of "bang", and threw the iron into the fire fountain on the other side again, and then smiled at Gu Yi: "Boy, I haven't seen you for a few months, but you have grown a lot?

Gu Yi shuddered angrily and said: "Don't talk nonsense, why did you arrest me here? You eat me and drink mine these days, and you still rely on your strength to bully people so much, and I raised an old white-eyed wolf, right?"

The old man was choked by what he said, although he rarely came out of the hole, it didn't mean that he didn't know anything, and during this period of time, it was true that several meals of food were sent to the entrance of the cave every day, and the liquor that lit the fire was poured into the stomach, not to mention that he also robbed Gu Yi of a lot of good things, eating people's mouths, taking people's methods, being blocked by Gu Yi, he really couldn't say anything to refute.

But the old dwarf's face was full of thick beard, and he couldn't see what his face was, so he smiled cheekily and said with a hard mouth: "You kid didn't take Lao Kui's Iron Courtyard Monument to swagger outside, right? What's wrong with eating you some blood food and drinking your drunk?"

Gu Yi glanced at him, took out the swarthy iron courtyard monument from his arms and threw it over: "Then I will return this broken iron brand to you, and none of us will owe anyone in the future."

The old man who grabbed the Iron Courtyard Monument was speechless, and he threw the Iron Courtyard Monument back with a smile, and said, "Okay, I'm looking for you kid, I want to ask you something."
