The island was round and very regular, with smooth edges. Its interior held only sparse white shrubs, just a meter tall and without leaves.
Yang Yi picked a spot at random to approach the island, since it all looked much the same.
He then turned the ship broadside, aimed the Waterlogged Cannon at the shore, and fired twice.
One shot was a Common cannonball, which blasted a hole in the coast of Salt Island.
The hole revealed that the island's surface was covered in a layer of salt frost a dozen or so centimeters thick, with loose, dark brown soil underneath.
The island was not made entirely of salt. A very thick layer of salt frost had merely precipitated on its surface.
The other shot was unusual. It fired a Human-Head Octopus, which smashed against the shore and became a puddle of mush.
Yang Yi stopped firing and scanned the island with Three Eyes instead, watching to see whether he had disturbed anything on it.
But he had not.
He switched to his ordinary vision and observed through a telescope for another few minutes, but still found nothing unusual.
Judging by appearances alone, the island seemed to have no moving creatures. It was a place of dead silence.
He fired another two shots, this time targeting the white shrubs on the island.
Both were solid cannonballs, plowing two paths through the shrubs.
Every shrub along their paths shattered, sending white dust billowing high into the air.

Yang Yi stopped and did not fire again.
From his observations so far, the island seemed to hold no danger, only masses of white salt.
But Yang Yi had walked through a desert made of salt before and knew that this salt might form human shapes and
