After a few days of sailing, probably because it was on the periphery of the dangerous sea area, Su Ming and the others did not encounter any "special" situations, but as they gradually deepened, the surrounding environment gradually began to appear strange phenomena.

The most obvious sign is that the ship's communication devices, which are used to keep in touch with the outside world, have completely lost their effectiveness in the chaotic magnetic field where the magnetic pole is unknown.

Any communication channel, as long as it is transmitted via a wireless signal, will become a harsh noise that is difficult to distinguish under the interference of chaotic magnetic fields.

In other words, Su Ming and Wu Tianming have already entered the interior of this unknown sea, and everything that follows can only be solved by themselves.

Either find out the truth about the strange phenomena in this sea before they completely lose their way, or ...... Any danger that may be encountered cannot be anticipated!

The loss of contact with the outside world was only the first obstacle Su Ming and the others encountered, and on the first night after sailing into this uncharted sea, an even more mysterious situation also appeared:

"Aurora."

The optical effect that would only appear in the near-polar region, but it was so abnormally in the temperate region of the Glory Star, and the aurora encountered by Su Ming was no longer a purely ornamental landscape that was harmless to humans and animals, on the contrary, it brought a huge trouble to the two of them.

Logically speaking, the aurora is produced by the excitation or ionization of molecules or atoms in the upper atmosphere by a stream of high-energy charged particles, which is a product of pure technology, but the aurora that appears at night in this sea area is obviously not so simple.

Brilliant and colorful light hung high in the sky, and the crux of the problem was not discovered until Su Ming returned to the rest cabin of the speedboat to prepare for sleep, that is, the aurora in the sky...... Has the effect of ignoring any occlusion!

The walls of the rest pod's room, the curtains of the bed, the quilt covering the head, and even the closed eyes could not stop the brilliant light effect from imaging on the retina!

This strange situation made Su Ming immediately alert.

You don't have to think about it, the aurora phenomenon that appears in the night sky in this dangerous sea area is definitely not as simple as an ordinary optical effect!

The unstoppable light continues to pollute people's vision, and short-term appreciation can be regarded as a rare sight, but when it exists for a moment, it will bring a terrible consequence:

Sleep deprivation!

In the human form, sleep is needed to "rest" and "recover" the body's various functions, and of course, in most cases, to achieve the best quality of sleep, it needs to be done in a comfortable environment as much as possible.

When people are constantly in a state of intense light pollution, the so-called "comfort" certainly does not exist, and it is not even possible to sleep at all.

After discovering that there was a special phenomenon of "aurora" in this strange sea area, Su Ming, who was completely sleepless, had a little more guesses about the previous disappearance of the ships.

……

"So if we sort out the clues we have so far, we can actually infer things from eight or nine."

Because of the existence of "light pollution", it should be difficult for any human being in this sea area to sleep, so Su Ming simply got up from the bed in the rest cabin and went to find Wu Tianming, who was guarding outside in the middle of the night, and summarized the clues they had.

After all, instead of closing your eyes and being stimulated by the monotonous light, it is better to share the "visual" pressure through other things on the ship, and reduce the presence of the somewhat dazzling aurora in the sky.

"How so? Su Ming, do you have a clue? ”

After Wu Tianming heard about the aurora from Su Ming's mouth, his mental state also became a little nervous, there was no doubt that the two of them had now gone deep into the dangerous sea area, so when he heard Su Ming say that there were inferred clues, he naturally couldn't wait to ask.

"Well, I have a clue." Su Ming nodded and stretched out the three fingers of his right hand.

"First of all, the chaotic magnetic field in this sea area means that there is no contact with the outside world, and short voyages can rely on the personal ability of the crew to identify directions, but if the time is extended, even the most experienced sailors will be lost."

"Second, it stands to reason that no matter what the purpose of the ships coming to this sea is, with the current level of technology, the vehicles manufactured at the current level of science and technology should not take more than 5 days to leave under the premise of sailing at full speed."

"Five days, the normal situation is not a problem, but if you combine it with this strange aurora that appeared at night...... That's different! ”

Su Ming thought about what he wanted to express, and explained to Wu Tianming lightly: "You close your eyes and feel it, the light pollution that stimulates your retina all the time, if the crew of the whole ship can't sleep for 5 days in a row, how much mental pressure will it bring." ”

"If I'm not mistaken, the aurora in the sky should not only appear at night, simply because there is daylight during the day, blocking their appearance, but the actual effect should not be discounted in the slightest."

"This is what these aurora lights do, through sleep deprivation, constantly exhausting the sailors who come to this sea."

Wu Tianming, who was sitting opposite, couldn't help but gasp: "You say that...... That's true. ”

"If you don't sleep for a day or two, your body can be overloaded and forcibly maintained, but after a long time, your mental state alone will collapse directly." Su Ming said, and mentioned the details in Hearthstone by the way: "You have also experienced with Saki Shimagaki before, a long-term and high-intensity thinking game, it is good to say that it is good to play 3 or 5 games, and if you hammer for more than ten hours in a row, there will definitely be a dead end in thinking." ”

"It's not a matter of personal strength, it's just that the body is limited and the brain is too tired to think perfectly."

"Then in this case......"

The corners of Su Ming's mouth curled slightly, still maintaining that calm tone, but the content expressed in the words made the listener shudder:

"Everyone is highly tired and nervous, and if there is any external event, throw even a small spark into it......"

"Boom."

These are the most basic possibilities that Su Ming deduced based on the situation he has mastered, if these speculations are true, then what appears now is just a foreshadowing.

The real killer feature, or the event that turned this sea area into the [Mooneater Baku] special effect line "No One Survives", should not have appeared yet!

Of course, for Su Ming, in order to explore this dangerous sea area, he also left a special backhand!

A trick exclusive to his hole cards!
