The power of the lightning bolt was great and created ripples in the Earth Fixing Array when it passed through the hole.
If Lin Mu had not made the hole, perhaps the Earth Fixing Array might have ended up getting greatly damaged. While Earth was good at withstanding lightning, one must not forget that this was still an array and was operated by thousands upon thousands of runes.
Each rune was made with spirit Qi which would be broken apart by the violent power of the tribulation lightning. After all, the Earth Fixing Array's function wasn't to stop or reduce the power of the Tribulation lightning.
Something like that was done especially through formation arrays like the Tribulation attenuation formation array. Thus even if the Earth Fixing array was technically stronger than the Tribulation Attenuation Formation Array, it couldn't bear the tribulation lightning bolts.
