Usually, when Ruins Chosen use this blessing, they connect with the earth beneath their feet, and even the vast earth veins formed from countless materials beneath the surface. Unless you dig up and completely remove the earth and veins within the connected range, nothing, even a large transport truck or a train coming head-on, could make you retreat a step.
If these two blessings combine, then the Chosen's own defense will soar to the sum of all materials within the range of their spiritual flow.
If it weren't for the interference and contamination of the earth veins during the Rain Blood Disaster using worms, Yue Chen might have just run straight at Ji Jue amidst bombshells and blasted him to bits!
Just these two blessings alone make Ji Jue's outing worthwhile.
Solid Rock and Earth-Connection are crucial cores among many Blessing Chains. Having them on hand means other Blessing Chains like Iron Wall City and Fire Hell Mud Plow are just missing some corner pieces.
