(Regarding the star core hypothesis, it's a character setting I made up myself, so don't really think there's any actual star core, maybe there is, maybe there isn't.)
However, the situation soon changed.
That is, after Jia Yan traveled a certain distance, he felt the rocks and other minerals of the planet ahead turned into high temperatures.
From sub-zero temperatures, it quickly rose to above-zero temperatures.
"It's over fifty degrees! Humans would pass out from the heat here."
Jia Yan was slightly delighted.
At this time, he was already more than three hundred kilometers deep inside the planet.
Then he grew even more excited, because up ahead, there was a large amount of magma.
The appearance of magma caused Jia Yan to feel satisfied with the current situation.
With magma, it can be confirmed that this planet's center is a liquid core, and at the very center of this core, a star core should appear.
