After the identities of the foreign players who infiltrated were exposed, the Special Defense Department could no longer remain indifferent as before. It was clear that they were here for the "Time Tower", whether it was for time evolution or props, they absolutely could not let them exploit this loophole. Thus, very quickly, the Special Defense Department dispatched an elite team to block from outside the mountains, maximizing the blockade of the prop's effective range.
Of course, space-time class props are not restricted by this range, but the existence of the "Time Tower" itself limits similar props; otherwise, these players wouldn't resort to such a foolish plan like digging tunnels.
