Bang, bang.
Several dull thuds traveled through the earth and air, reaching the Daoist's battle puppet's ears.
The fortress's main structure, embedded underground, trembled faintly, and the hangar where Wang Jixuan's battle puppet stood shook lightly as well.
The Mountain Protection Grand Formation's light barrier quivered.
But the tremor was not especially obvious. The formation diverted the powerful impact into the earth, while its various formation bases operated steadily.
