Soul travels through the world of immortality

Ling Tian flew over and approached this hazy area, discovering that it seemed to be a barrier composed of netherworld energy.

The mist is mixed with the atmosphere of the netherworld, as if it is as ethereal as a spirit body.

Ling Tian advanced slowly and landed at the bottom of the mountain, pressing the snow on the base of the mountain with a crunching sound.

Li Mingyang controlled Ling Tian and slid for a while. The breath in front made him frown and remain silent.

At this time, he had secretly used the Underworld Art, which slightly alleviated the pain of physical tearing.

Hu Ailin sat next to Li Mingyang, using his devouring power.

However, Xingqing remained unmoved and stared at the hazy area in front of him, as if he wanted to find a breakthrough and successfully enter the Nine Netherlands.

Ling Tian stopped completely. They all jumped off the flying boat and stepped on the thin ice, feeling down to earth.

Walking into the white barrier, I found that it was not just the air of the netherworld, but seemed to be a solid gas, blocking the breath of the Nine Netherlands.

Li Mingyang walked into the barrier, touched it with his hands, and felt its temperature.

Before time travel, although his studies were above average, he was particularly good at chemistry.

After preliminary judgment, he guessed that the barrier should be dry ice formed by the solidification of carbon dioxide.

If this is the case, it can explain why the land of Jiuyou is so cold and snowy often makes life unable to survive. It can also explain the fog formed by the storm of Jiuyou.

Because dry ice sublimates easily at room temperature and can dissipate a large amount of heat when vaporized. When it sublimates at normal pressure, the surrounding temperature can drop rapidly. Therefore, dry ice will liquefy when it sublimates in the air, and even further condenses water vapor in the air.

Li Mingyang quickly turned around in his mind, trying to figure out how to break this barrier.

If your guess is correct, dry ice will sublimate into gaseous carbon dioxide at high temperatures.

However, the melting point of dry ice is -78.5c, which means that the temperature in Jiuyou Land should be lower than this temperature, otherwise dry ice cannot be formed.

Li Mingyang speculated whether the Jiuyou Storm was caused by the rising temperature inside, which sublimated the dry ice, causing a large amount of carbon dioxide to leak out, forming fog.

Li Mingyang put aside these chemical thoughts and asked Xingqing to use his flaming rod to strengthen the real fire, condense it to a point, and melt (sublimate) the barrier.

Xingqing looked at Li Mingyang with strange eyes and asked.

"Is this possible? It seems to me that the barrier looks like ice but not ice. It seems to be a restriction left here deliberately, but it is too solid and loses the restriction effect."

"I can't explain this to you, but when you burn it, you can only burn a passable outline, and the rest is up to me."

Xingqing kept staring at Li Mingyang with suspicious eyes, as if he wanted to find a trace of uncertainty in his expression so as to find a reason for his obedience.

Taking out the flaming rod, Xingqing stood at the position designated by Li Mingyang, burning the barrier according to the way he gestured.

There was billowing white smoke in the haze, and it seemed that the barrier at the burned location had become thinner. He cut bit by bit until part of the barrier was burned through, and then he believed Li Mingyang's judgment.

He worked hard to release the real fire, and this barrier reminded him of the blue ice that froze Grandpa Meng Xiaohe.

"This thing seems to cut better than Grandpa Xiaohe's blue ice. Are they the same thing?"

Li Mingyang recalled that the Heavenly Fire Stone given to them by the Immortal in White could also generate a large amount of heat, but it was wrong to think about it. In terms of chemical properties, the solid hardness of dry ice was not high, but the blue ice was extremely hard.

"Probably not. The blue ice did not form mist at that time, and the temperature of the altar was not low."

At this time, the flaming rod had cut a big hole in the barrier...
