Soon, Ryan James indeed let Rome Thomas witness a miracle.
Under the operation of professionals, the repeated impacts of the swinging sledgehammer had even begun to deform the wall, slightly indenting it on the opposite side, yet the main structure remained unchanged. Not even the impacted areas showed any cracks.
Even after being blasted with a rocket launcher, the wall still maintained its integrity.
It was only a single wall, supported by some pillars at the back to form a bracing structure, so it really was just the wall bearing the force. If rocket bombardment couldn't bring it down, not to mention that massive pendulum hammer, you can imagine how sturdy it was.
