Yu Baiyi couldn't help but shout, "Earthquake!"
The Grand Elder had been caught off guard as well. That jolt had nearly thrown out his old back.
After coming to his senses, he first looked at the formation mirror, then at the formation's core, before crying out in alarm, "The formation is broken!"
The grand formation truly had been broken.
Feng Jun had actually been considering whether to borrow the power of crossing planes to destroy the grand formation.
However, he was unclear on how to borrow that power, and he could not predict the consequences.
That was why he had first used explosives, hoping to force Jade Ruins to show itself and throw open its gates to invite him in.
Since he was using explosives within the country, he had used less at first. It was not only because he did not want to cause too much destruction, but also because he was worried the disturbance would be detected by the Earthquake Administration.
When the first attempt had proved ineffective, he had planned to go big. Then Shen Qingyi had stepped up to cause trouble again.
Feng Jun could have killed her, but... there had been no need. He had also happened to notice something unusual about that stone, so he gave it some thought.
After testing it twice, he confirmed that the stone was related to the grand formation, and the idea of borrowing plane power arose again.
But... he truly could not predict the outcome. What if he moved the entire grand formation to the Phone Plane?
With that concern in mind, he had run deep into Pacify Arms Mountain. In any case, with the Energy Points in his Stone Ring, whatever he moved over would not be large enough to fill the depths of Pacify Arms Mountain.
