Other than power, there was still one more characteristic the earth had: it endured the weight of everything in the world.
The world nurtured all lives and endured their weight. Regardless of if there were volcanic eruptions, earthquakes, hurricanes, tsunamis, or various other natural disasters, the earth quietly accept them all.
Even if a nuclear bomb were to explode or if it were the attack of a Divine level expert at full power... to the earth, they were all nothing.
Erudite, profound, vast... These were other characteristics the earth had. This was also the greatest level of profoundness behind the Mountain Shifting Sword. As the saying went, one had 'to be calm, enduring, and unmoving like the earth'.
Under added levels of increasingly violent power, at the very end, what the Mountain Shifting Sword possessed was the most powerful defence.
