Nightmare scenes are based on their actual experience in the earth doomsday.

They were trapped for two hundred years in the game by a certain alien lifeform who destroyed their earth.

While they are trapped inside the game, other humans that are not trapped became s*aves to this alien. Only tens of thousands were left, and they were forced to limit their reproduction by a total of hundred babies a year.

XB's role is not just a bookstore owner but also a game master without the actual authority.

LQ is the one who actually escaped the game but was forced to return inside it with erased memories.

The floor does not matter, as long as they, both actors and mission takers, all sleep, the ultimate nightmare will be triggered.

The highest floor is unknown but there is a lone surviving mission taker found at the 65th floor near the end of the story.

They were helped by a foreign alien life form that was the enemy of the one who trapped them in the end.

Mankind was able to free itself from this alien colonozation. Humanity was restored.

XB's and LQ's bodies were actually destroyed while they were in the game. But the good thing is, the foreign alien helper created new bodies for them, which looked the same as in the game and even with the same stats.

After getting out, XB and LQ are living well. XB as a live broadcaster and LQ as an no.1 athlete in all the physical competition against other alien races. Lol

before they enter Xu Bei's nightmare

I feel like it's only XBJ and LQ who got a True End, while the rest got the Normal End. I wanted more stories of the survivors since Mu Jiashi and Su Enya are the only ones who had a few lines dedicated to them.

I feel really sad thinking about them. All the people they loved were in an era they left behind-- 200 years ago. They're all exhausted. They didn't integrate well with the new society. Aside from XBJ and LQ who had no choice, the survivors were actually also offered bionic bodies (so they could live longer than the human lifespan) but very few people took it. I think they were just glad that they could finally die in the way they wanted to, which is sad because that's a really low standard, but understandable too.

I guess it's a mercy that they weren't deposited on an Earth with only rubbles and nothing else since the Fijeka (?) at least kept 10, 000 humans outside (as s*aves, but they at least have freedom to watch XBJ's stream lol).

Also loved that bit that Detective Dalao was almost taken away by Fijeka (?) as a cannon fodder for war, but he was too sick so they eventually left him alone (This wasn't explicitly stated but I made that conjecture when the descendant of the game maker told the survivors when they just got out about the young man in passing, and the fact that Detective Dalao disappeared for two weeks).

Earth experienced a world wide madness. For a year, the people on earth strive to get on their feet and stand up, only to see the world on fire.

The end of the word they experience is divided into three stage.

1. the world wide madness that lasted for a year.
2. the sky fire--the descend of the aliens
3. the emergence of the narrow building/tower.

If the alien invasion happen in other novel, then it will truly be hilarious.

People tends to laugh at the topic of aliens, but this series ain't funny at all.

Amidst the battle of AI: Virtual vs bionic bodies... the Virtual AI made a mistakes somehow, resulting to the madness of unknown primitive planet: Earth. Since the earth didn't know about the truth about the universe, they are not part of the Universe something, so the race that discovered them automatically owned them. So no one in the universe care if the earth perishes.

Unlike other novels with organizations that protect primitive planets, this novel, I think tends to be more realistic. After all, Earth is at fault that they didn't know a thing about the universe, and other races in the universe ain't responsible if anything happened to them.

After the one year madness in earth, the sky fire--the descend of the aliens came. Only a few days, astronomer discovered a UFO heading towards the earth.

Then when the skyfire descend happen, the event in of the maze came.

Before the alien came on earth to clean up the mess they did accidentally, they send message on earth a month before the alien begin their plan. But the people on earth didn't want to comply and so they made a plan to imprisoned the aliens. And that is the maze plan.

But in the end they didn't succeeded. And so humanity fell.

After that, the alien build the narrow building/ tower to test/imprison human.

I can't say the ending was the kind of satisfying ending that I wanted. It was kind of bittersweet in my opinion, but I can't help but think that the way it ended really tied back into the whole theme of the novel.
