Neptune was the farthest planet from the Sun in the Solar System.
Jiang Siming had not come here to sightsee. He had come to "restock."
There were vast quantities of diamonds on Neptune, all beneath its atmosphere.
But with Earth's current level of technology, there was simply no way to pass through Neptune's atmosphere.
Neptune's atmosphere was terrifying. The outermost layer alone consisted of methane and hydrogen. Deeper in were thunderstorm clouds, followed by water-ice clouds and superheated clouds.
At its coldest, the temperature could reach minus 300 degrees Celsius, while at its hottest, it could soar past 1,200 degrees Celsius.
Even the most advanced exploration satellites might be instantly melted after entering.
That was why, to this day, humanity had not landed on a single one of the eight planets.
Even Mars, which had the lowest danger factor, had never been reached by humans. Only probes and monitoring satellites had been sent there.
The only celestial body humans had landed on was the Moon. It was the closest and safest.
With Earth's current technology, Jiang Siming could say pessimistically that humanity would not achieve the goal of colonizing another planet within a century.
They could not even handle the planets in the Solar System, much less colonize planets in other star systems.
Fortunately, he had the Fragment Store to help him. As long as he gathered enough fragments, none of this would be a problem.
For now, however, Neptune's atmosphere had become an obstacle blocking Jiang Siming from harvesting diamonds.
Unfortunately, while it could stop other Earthlings, it could not stop Jiang Siming.
He was a mighty Spirit Transformation stage expert. How could he fear a little thunder and a temperature difference? Not to mention that he had taken the Space Gene Potion.
Even without it, these temperatures and
