Even so, Xu Yang still felt cold all over his body and suffered heavy frostbite. The spirit beast is a spirit beast. Even if it is only a first-level level, it has a power that the peak Xuan Emperor and the Invincible Xuan Emperor cannot match.

Looking at the entrance of the cave that was blocked tightly by the ice, Xu Yang shook his head and smiled bitterly. It seemed that it was difficult to get out from this side, so he could only hope that there would be another exit in the cave.

This is a horizontal cave, which is cylindrical, as if it is formed naturally. The walls around the cave are covered with cold and uncooked ice, and I don’t know how many years have existed.

Xu Yang took out the twelve night pearls again and hanged above his head. He slowly walked towards the depths of the cave with the faint light.

The deeper he walked into the cave, the lower the temperature. Later, Xu Yang's face and body were covered with fine ice slag. The mysterious protection he had opened could not be used to isolate the cold. This feeling was like an ice master, emitting a powerful ice cold power, which was unbearable.

Later, Xu Yang could only stretch out the Lihuo Heaven Palace, and a circle of red flames gushed out from his body, which drove away the coldness and allowed to move forward.

Finally, Xu Yang walked to the end of the Cold Ice Cave.

The vision suddenly opened up. Xu Yang was shocked when he saw the end of the cave with his concentration!

At the end of the cave, there is a huge spherical space with a diameter of thousands of feet! There are holes on the inner wall of the spherical space. Obviously, each hole represents an ice cave, which is the same as the cave that Xu Yang had worked hard to drill into.

Although these holes are surprising, what is most surprising is the floating silver-gray airflow inside the spherical space.

The silver-gray air flow rolled and contained the extremely pure ice power. Even if you just take a look, you would feel the illusion of a cold neck.

"That's right, this is the extreme energy of the ice pole attribute, the zero-world cold air! But I didn't expect it to have developed to this scale..." said the bronze plate.

"Is this large scale?" Xu Yang said in surprise. He could see that this so-called zero-boundary cold air is only about one foot in diameter, which is not much large.

"Xiao Xuanzi, the Zero Realm Cold Air has compression characteristics. During the gathering process, it is still condensing and compressing, so it is growing very slowly. Such a large Zero Realm Cold Air is probably only possible after hundreds of thousands of years of accumulation."

Xu Yang was a little shocked. No wonder he felt that the cold current was unstoppable along the way. It turned out that this Zero Realm cold air had grown to the point where even the bronze plate was amazed. On the other hand, Xu Yang had encountered the Thunder Tribulation Pearl and the Chijitian Flame, which he had encountered, did not have such terrible power.

"Okay, the greater its power, the stronger the sixth heavenly palace I built." Xu Yang looked at the Zero Realm cold air in the rapid rotation and took a deep breath.

A cauldron flew out from Xu Yang's head and approached carefully toward the ball of cold air in the zero realm.

The Supreme Melting Furnace has now been available in five different colors and its intensity has been greatly improved. However, this Melting Furnace cannot withstand the biting cold. As soon as it leaves the body, a layer of white frost appears on the outer wall of the furnace.

Just moving forward a few feet, the outer wall of the Supreme Melting Furnace was covered with a thick layer of ice crystals, and the sound of overwhelming freezing cracks came from the cauldron. Xu Yang was secretly surprised and quickly swallowed a "Blue Water Yang Ji Pill".

The treasure medicine refined by the Green Phosphorus Demon Fruit has the wonderful effect of alleviating the extreme energy. After Xu Yang swallowed the pill, the Supreme Furnace emitted five-color light, and the ice crystals on the outside cracked and fell downwards.

Xu Yangneng saw that there were also a trace of impurities in these ice crystals, which were obviously a little impurities washed out from the Supreme Melting Furnace.

However, the sixth refining process has just begun, and the real test will be later.

Under the cover of a layer of soft green light, the Supreme Melting Furnace slowly approached the ball of zero-world cold air, and the suppression of the cold current became stronger and stronger.

When approaching the range of the zero-level cold air, the zero-level cold air in the rapid rotation suddenly changed! A tiny silver-gray cold air floated out from the sphere of the zero-level cold air and wrapped around the supreme furnace.

This tiny silver-gray cold air suddenly expanded after breaking away from the sphere of the zero-boundary cold air, and soon turned into a cold air as thick as a bucket, swallowing the supreme melting furnace!

Xu Yang's eyes turned black, and the Supreme Melting Furnace was united with his mind. Now his soul had an illusion of being frozen! He gritted his teeth and persevered, silently reciting the Mingwang's mantra, like a statue, sitting cross-legged, enduring the refinement of the cold air like that of the bucket.

"Very good," the bronze plate was not surprised but happy, typing, "If it is the zero-boundary cold air after high compression, you should not think of cleaning it at all. Now a trace of compressed cold air is attracted and turned into its original appearance. Such zero-boundary cold air is suitable for you to clean the furnace and cauldron."

Xu Yang had no time to distract himself, but he also understood the meaning of the bronze plate. The highly compressed zero-world cold balloon is a terrible thing that you don’t touch even if you touch it. It is this extremely cold ice eye, which has accumulated over hundreds of thousands of years or even longer years. Once it explodes, even the strong Buddha dare not face it.

As the cold air of the zero-world thick as the bucket was washed away, the Supreme furnace was stripped of a trace of impurities, and the whole body became more and more crystal clear, as if it was carved from colorful crystals.

"Okay, now we should use our mind to engrave the ice runes on the furnace cauldron to achieve the sixth integration of the magical artifacts." Xu Yang breathed a sigh of relief, and a blue mind power extended out and crawled along the outer wall of the Supreme Melting Furnace.

What Xu Yang didn't know was that just as he was working hard to practice, an uninvited guest came from the extremely cold eyes of Liushang Kingdom.

Tian Zhihang, wearing a blue background and white cloud robe and indifferent face, slowly flew here. Behind him were several ordinary disciples from the Immortal Alliance branch, all of whom were responsible for monitoring this dangerous place.

"How long has that green black light entered the extreme ice eye?" Tian Zhihang asked lightly.

"Senior Report Tian, ​​he has been in for half a month!" An ordinary Xuanzong disciple lowered his head and answered respectfully.

"Have he not returned?" Tianzhihang continued to ask.

"Yes, we have been closely monitoring it, and no one has returned from the extreme ice eye," the Xuanzong guessed, "The extreme ice eye is very dangerous. That man is only Xuanjun's strength and may have died. Senior Tian, ​​don't worry."
