Looking at the terrifyingly huge shadow, Song Chi was absolutely sure that this must be a Third Rank Level sandworm, and not just any ordinary one, but the kind at the Third Rank Peak, possibly even a pseudo Fourth Rank Level creature.
Otherwise, it wouldn't have been possible to inflict such damage on a Dark Matter Energy Shield Generator that had been enhanced to LV30.
To put it simply, a normal creature from the Starry Sea of the Third Rank, when faced with an Orange Quality Dark Matter Energy Shield Generator, would do well to deal more than fifty thousand points of damage. Those that aren't adept at attacking wouldn't even be able to break through the Dark Matter Energy Shield (their attack damage being lower than the defense value of the energy shield).
From this, it's evident how terrifying it was for a single strike to deplete over 800,000 shield points.
