After the Solar Divine Saber and Metamagnet Divine Saber have absorbed the Golden Origin Water, they have turned so heavy that Swords Gate Mountain has sunk into the ground and erupted the underground volcanoes. Rifts deep into the underground cracked across the earth's surface and lavas were extruded out above the ground.
The sudden outbreak of the catastrophe has alerted the whole Swords Gate, it was no surprise Jun Sixie had mistaken it as a hostile invasion.
Quietly without making a single noise, Zhong Yue quickly kept the two sabers away into his Yuan Shen secret realms. He didn't dare to surge them back into his mortal body as the sabers' weights would still persist in sinking the mountain through his mortal body.
The Yuan Shen secret realms were dimensions opened within the Yuan Shen, they weren't in the same dimensional space as the world. Thus, the sabers would not affect Swords Gate Mountain when kept in the Yuan Shen secret realms.
