Seeing this, Yang Ji couldn't help but reveal a smile on his face.
However, this was not enough. He immediately flew above the magma pool, brandishing his sword and hacking off ninety percent of the remaining Fire Crystal Stones, leaving only one piece untouched—the one which the roots of the Flame Tree were planted in.
Yang Ji did not wish to eradicate the tree's source completely; by leaving one piece of Fire Crystal Stone to absorb the power of the magma, the Flame Tree would be able to survive. In several decades or possibly a hundred years, it would bear fruit again.
Similarly, leaving that piece of Fire Crystal Stone was also done so that it could continue to absorb the strength of the magma and grow stronger. Perhaps in a thousand years, this area would once again become a field of Fire Crystal Stones, nurturing another Earth Spirit Fire.
