On Earth, there are places where heat can be obtained almost endlessly, such as the volcanoes scattered around the world. However, for the goal I aim to achieve, the power with which volcanoes release heat is still insufficient. I must find a more efficient source of heat, deep underground.

Ming Zhuo misunderstood one thing; it's not only stars in the universe that can endlessly release heat, but Earth can too. Tens of kilometers beneath the surface, past the Earth's crust, lies the mantle—a layer filled with terrifying magma that has been scorching hot since the birth of the planet, billions of years ago.
