Boom boom!
With two ear-shaking roars, the entire underground structure began to vibrate violently.
The debris that splashed was like bullets shooting in all directions.
The Thunder Spirit, who was lucky to dodge the cannonball, was instantly pierced by dense stones and dispersed into floating silver serpents.
The level above.
The sudden trembling made everyone's face change.
Anxiously, they looked up at the ceiling above.
If this place collapsed, they would all be buried here.
Even the ruins of the city above might cave in.
During the violent trembling, a wide area of the first level collapsed.
Fortunately, the second level was unaffected and the entrance was not blocked.
This made everyone breathe a sigh of relief.
Once the shaking stopped, Beata asked, "What happened?"
"There's a Mammoth down there, carrying two large cannons," Fang Hao said, patting the dust off his head.
"A Mammoth? Like the ones at amusement parks?" Beata exclaimed.
