The core material of the giant sword used by Bone King was the same as the National Sword, which was star soul meteorite iron.
This was a special metal that was produced in the core of a star at the beginning of its birth. It was indestructible and contained a huge amount of energy.
Only when a planet was destroyed or exploded would the meteorites fall into the void of the universe with the shock waves of the explosion, or turn into meteorites and fall on other planets.
It was because of the star soul meteoric iron that the giant sword had not decayed.
At this moment, as the star soul meteoric iron was extracted, the stone sword instantly turned into a cloud of dust and dissipated in the wind.
On the other hand, most of the cracks on the nation-guarding sword had disappeared, leaving only two large cracks.
