The underground world beneath the demon cave was much wider than Alan had imagined.
Countless amounts of Earth's fire lava flowed wantonly underground.
The air was filled with the rich smell of sulfur.
The Earth's fire could even melt through space. Over time, it had even left a dome-like ceiling in the underground.
There were crystals left behind by the dissolution of all kinds of minerals everywhere.
These were all good materials for refining artifacts.
Moreover, after being baked by the high temperature of the Earth's fire, there was no magazine, and it could be used directly.
It was impossible to find such pure minerals in any blacksmith shop in the nine regions, but here, they were like garbage, floating in the lava.
Alan recalled that he still had a dragon horn in his arms.
He randomly picked some ores and put them into his storage ring. Then, his eyes focused on the center of the Earth's fire.
In the endless sea of fire surrounded by countless lava, there was actually an icy spring that was emitting cold air.
With just a glance, a layer of frost condensed on Alan's eyeball.
The demonic qi in his body was ready to move. However, the Earth's fire golden core in his dantian automatically rolled and separated a stream of heat to wrap around his eyeball.
Alan only felt a warm current flow through his eyes.
Looking at the icy spring again, there was no discomfort at all.
Even if Alan had never learned how to refine artifacts, he knew that the extremely cold things produced by the extremely hot places were definitely not simple.
Activating the Earth's fire golden core's heat to wrap around his entire body, Alan carefully came to the edge of the cold spring, but found that it was empty.
A pool of spring water came out, but there was nothing inside.
Even if there was a pearl, or even a jade, it would have been fine.
The cold spring was only the size of a sea bowl. It was a slightly irregular and rectangular in shape, with rounded corners. It was more like a box that stored something.
Alan suddenly recalled that when Wine Fairy gave him the nameless secret manual, it came in a small box.
His memory was already somewhat fuzzy, and it was not real.
He reached out his finger and carefully inserted it into the icy water. A light blue icy line played with his wrist all the way up and quickly spread to Alan's shoulder.
It was clearly extremely cold and icy but Alan did not panic at all.
Instead, he had an indescribable feeling of perfection.
The icy line went all the way to his dantian and met with the Earth Fire's internal breath.
The two canceled each other out, as if they had never appeared before.
"Roar!!
"I can sense the demon lord's aura!
"It can't be wrong. The demon lord is here."
The three-headed blue-winged sea dragons had just returned to the dimensional space when they suddenly became irritable again. They suddenly stuck their three heads out of the dimensional door and roared.
This time, their senses were very real.
It was as if they were right beside him.
In that instant just now, it was as if a cold little hand was stroking its own horn.
It was gentle and warm, as if it had returned to the dragon egg.
Ai Li looked at its intoxicated expression and could not bear to tell it that its horn was broken.
"The feeling you had just now was only an illusion caused by the loss of the horn on your head and the numbness of the wound when it came into contact with the air."
Without the demon lord, the three-headed blue-winged sea dragon was the strongest existence in the demon sect with the highest backup.
Even Ai Li had to be polite to it.
No matter how much he slandered it in his heart, he had to comfort it on the surface.
Qiu Ya sat cross-legged on the one thousand and one stone step and suddenly felt a slight vibration under her butt.
A warm current surged out, burning hot.
It was like a red-hot iron.
"So hot, so hot!"
Qiu Ya suddenly jumped up and covered her butt with both hands, looking aggrieved.
Senior sister Bai Ling had already escorted the others back. She was the only one who insisted on waiting for Brother Alan.
For some reason, it was getting hotter and hotter.
If Alan still did not come, would she turn into a roasted sweet potato?!
Qiu Ya thought of the soft, sweet roasted sweet potato and could not help but lick her lips.
Although she was a little afraid in such an environment alone, for some reason, she felt a little greedy. What should she do?!
"Why aren't you leaving? Be careful, or you'll turn into a roasted sweet potato."
A gentle voice appeared. Alan had appeared behind Qiu Ya at some point in time. Even the surrounding air seemed to have become less hot.
"It's sweet potatoes. Qiu Ya wants to eat roasted sweet potatoes!"
When Qiu Ya saw that Alan had returned, she happily dived into his arms.
She rubbed her head against the ground and did not forget to ask for good food.
"Alright, alright. Let's go up first."
Alan grabbed Qiu Ya's arm with one hand and lifted her up with a little strength. It was as if he was riding on clouds and mist. In a flash, he had climbed hundreds of levels.
After fusing the cold air and Earth's fire true energy, there were no changes in Alan's body.
He also did not advance any further from his original Sky Demon Realm.
He was not disappointed. After all, if he went any deeper, he would still have to ascend.
However, when Alan walked back, he found that his body had become much lighter.
When he walked, he was so fast that there was not even a shadow.
No matter what, Qiu Ya was a Nascent Soul Realm cultivator. She had been squatting on the stone steps waiting for Alan, but she did not even see a shadow.
If she wanted to be an enemy, Qiu Ya would not even know who killed her before she died.
This was under the situation where Alan was carrying endless pressure and still going up.
There was a very magical place in the demon cave.
As long as you went down, no matter if you went down a level or a thousand levels, the gravity would be the same.
However, as long as you turned around and climbed up, without going up a step, the gravity would double.
Alan ran to the bottom of the cave in one breath, and even absorbed a gust of cold air from the mysterious underground fire cold spring before running back.
By the time he reached Qiu Ya's side, the pressure on his body was already 2,000 times greater.
However, even so, Alan's speed was still so fast that even a Nascent Soul Realm genius cultivator could not catch his shadow.
Even if he was an expert of the Sky Demon Realm, it was still a little too exaggerated!
Alan himself felt that he was a little too strong.
It was fine if he could not beat her, but he could not even see her shadow. This kind of strength had already surpassed the limits of a human.
Holding on to Qiu Ya, the two of them began to walk back.
Alan automatically withstood the pressure on Qiu Ya's body, so the little girl did not feel it at all. She was still in the mood to rub her head against Alan, pouting and acting coquettishly as if she wanted to roast sweet potatoes.
Not long after the two of them walked, they met people who were climbing the stone stairs in front of them.
During the time Alan went underground, people were already walking back.
However, due to the pressure, after a few steps, there were already a few people lying on the ground, unable to move.
Fortunately, the Earth's fire was sucked away by Alan now, or else those guys would have long been vaporized into dried meat.
Alan walked behind the crowd, silently putting all the pressure on his shoulders, wanting to test where his limit was.
The people inexplicably felt their bodies lighten.
The heavy burden on their shoulders was lifted.
Ai Li calmed the three-headed blue-winged sea dragons. When he turned back to the side of the catacombs, he saw the people supporting each other as they walked out of the stairway.
Hundreds of people went in to climb the stairway, but all of them came back!
"Is the stairway broken?"
Ai Li's face was full of disbelief, and his eyes were full of suspicion.
