Originally, Zhou Tian hoped that his blacksmiths could create a miracle. In fact, though Zhou Tian collected all kinds of combustible objects to meet the needs of his blacksmiths, whatever the final temperature when those things ignited and burned, it was not enough to melt the piece of ore.
So far, Zhou Tian knew that if he wanted to melt that ore, there were probably only two places that could provide a flame with high enough temperature that would not interfere with the ore's ability.
The first place was obviously the sun.
Although the world might have changed, the stars shouldn't have undergone major changes. Therefore, even if the sun above Zhou Tian's head was not the one he remembered, if he could really reach it, the high temperatures inside the star would likely melt the ore, no matter how high its melting point.
However, despite the accuracy of Zhou Tian's conjecture, realizing it was likely impossible.
