Diamond Rain Asura Arena

"Mm,"

"The temperature here is a little low~~"

Standing in the low orbit of a pale cyan, jade-like planet, his sister gave that assessment.

"Only minus 220°C. That's not particularly low—but it is indeed the coldest atmosphere in the Solar System, even colder than the more distant Neptune."

This was because Neptune's core possessed temperatures of 7,000°C, radiating immense heat outward.

As a result, the more distant Neptune actually had a warmer atmosphere.

Yu lifted his chin toward the jade-like planet before them.

"This is an 'ice giant.' It's only natural for it to be colder."

The planet the two of them were evaluating was Uranus!

One of the Solar System's eight planets, it was the seventh planet from the Sun. From the outside, it was a tranquil, bluish-jade world.

It was called an 'ice giant' because although its atmosphere was still primarily composed of hydrogen, beneath that atmosphere lay a world made of ice formed from water, ammonia, and methane. That was right—this planet's core had been compressed into a frozen state.

But that did not mean the planet's interior was cold. Quite the opposite: due to its immense size and low thermal conductivity, Uranus's internal pressure could reach hundreds of GPa, while its temperature could rise to several thousand degrees. It was truly 'cold outside, hot inside.'

"Come on, I'll show you something good."

Yu reached out and took his sister's hand. His clone had already planted a branch on this planet beforehand.

Now, with the chakra coordinates present everywhere, the two of them could directly reach the planet's surface without passing through the atmosphere.

Flash, ×2

With a flash of light, two figures appeared above the frozen planet.

"What are we looking at?"

As his sister asked curiously, Yu had already raised a hand toward the sky.
