Before song qingxiao entered the battle of the gods, she had melted the surface of the two Mystic crystals with green flames and wrapped them in spiritual power. The surface seemed to be covered with a layer of surging luster.
Because it was made of green flames, the mystic crystal glowed a faint green due to the influence of fire spiritual power.
According to su Wu, this Mystic crystal was extremely hard. Even though she had spent so much effort, she had only managed to refine it to 30%, roughly removing the impurities in the mystic crystal.
Only when the dagger had been refined to 40% would the crystal start to liquify and continue to repair the missing parts of the dagger.
