Previously, the light enveloping the Phantom Lin Yuan had prevented Lin Yuan from sensing the outside world directly.
As a result, he had no idea whether there was actually seawater outside.
He had merely inferred from their journey that this Star Sea should lie beneath the Abyssal Sea. So although it looked like outer space, it might simply have been seawater with properties similar to outer space.
But Lilia's words, together with the appearance of these three moons, immediately made him realize something was wrong.

Coupled with the three moons in the distance, this was probably genuine space, rather than some sea that resembled it.
Lin Yuan suddenly recalled that when he had built the Lookout Platform, the system had requested "materials from space," not "materials from the Star Sea."
It was possible that the system had deliberately called the Star Sea beneath the Abyssal Sea "space" to avoid knowledge pollution.
But it was more likely that there was no Star Sea, only genuine space.
Many thoughts flashed through Lin Yuan's mind. Then he focused his attention and carefully examined the three moons.
The three moons were half solid and half illusory, giving the impression of projections.

"The Nether River Monarch's Certification!"
He instantly realized the true source of that summons.
At the same time, he finally understood why, although the Sunken Ones were people who had died in the ocean and whose bodies should ultimately
