Arc 1 c1-37 | Frontier Town

I talked the most about this ark because it is the most mentioned in other reviews. Particularly as this seems to be the only arc involving r*pe. XR sees this three times, once with CH. The complaints are about the third time, specifically CH's lack of bedside manner and the author's lack of character development for a female character. I'll bring this up in detail later.

This arc is a cruel world where the protagonists are directly thrown into a human country invaded by a strong horned race called "Barbarians." The enemy appears and starts a massacre before anyone has time to say hello. All but three testers die in this initial melee. The MC would have been one of them if not for some "friendly" help by the man in a suit. They meet up again later and the other man's ambition leads the protagonist into going above and beyond as well.

It is very obvious that the largest difficulties in this world are adapting to the sudden change and grasping the ability to kill another intelligent species. The danger forces the testers into a corner where they must act. Inaction is a dead end.

The only other tester to survive was the only female in their group, purposefully left alive by the barbarians as a s*x s*ave. This is not described in detail and I wouldn't want to read about the details even if it were. Other reviewers might criticize the author for not putting enough emphasis on caring for a r*pe victim, but I think the couple did enough under the circumstances. Every tester had to fight to survive or die.

XR gave her clothes, a weapon, and a hiding space. He went back to her at least twice to give opportunities to join the battle which she refused. She is never seen again and it is likely she does not earn enough points in the mission to survive. The girl is traumatized, but her unwillingness to take any step forward on her own or even to revenge against some barbarians has doomed her.
I think her response is relatively normal and does not paint women in a particularly bad light. The message her character sends would have been the same if she were a man. She ultimately does not do anything to drag her fellow players feet beyond asking XR to stay with her in hiding. She does not stab them in the back like another reviewer predicts, although this may be due to the protagonists not giving her the opportunity. I think given enough time she might have even figured it out, but the enemy waits for no one.
The ML is displeased that she wants to drag his teammate down, but he initially saved her without hesitation. He does not mind her doing her own thing and does not force her to act with them. Simply put, he has no expectations for a pig teammate beyond them not dragging back the team with their own unwillingness to act. His own life is also on the line. There is no time to be a counselor for her. He and XR did what they could to give her chances and they moved on once she refused.

I think her character and her experience show the extent of failing to follow the mission and the dangers involved. The author really did use her as a tool person in this sense. As for why none of the men were r*ped? Who says they weren't? The barbarians would prefer to kill the strong and targeted the weak. The man would have to be special enough to risk the chance he is able to fight back, but it doesn't mean it didn't happen. The protagonists stopped the crimes they could. The MC later finds the first family he saved dead showing their efforts did not have much effect in the early stages of the mission. The third tester was probably kept alive and brought back because her will to fight was so weak. It's enough for me that all of the rapists die. If I remember correctly, at least one gets his manhood chopped off first.

It's also clear that the reason she was not accepted was a personality incompatibility that added too many risks when you compare her to others the duo help later. Their third teammate does not excel nearly as much as they do. He is a bit cowardly. He stands out because he is only willing to risk himself. He is a good person willing to work hard, so the main couple takes good care of him across many worlds. This shows that they are able and willing to carry others. CH is a grouch, but their offers to help her were not false. They made the situation and the terms of cooperation clear.

Arc 2 c38-51 | The Battle of the King

This starts out like an escape room that eventually evolves into a battle royale. It's very bloody. The protagonist learns the benefits of hiding his identity as a tester.

Arc 3 c52-67 | Wilderness Guest

XR and CH meet again. They work together with some other testers in this arc to protect newbies. This arc really takes the survival aspect seriously. All food and drinking water supplies in the space are restricted. Luckily they can still use water reserves for bathing. CH finds a way to follow XR into next mission and find him irl to confirm relationship.

Arc 4 c68-83 | Bloody Battle in the Wild

Real life battle royale where evil scientists pit contestants against mutant animals.

Arc 5 c84-113 | Deep Water and Fire

This is a world of

extreme tourism! Testers must compete in a strange boating race. This arc has a major twist in its backstory that gives the protagonists a chance to steal information on advanced technology to use one day irl. They soon start planning a research base together.

Arc 6 c114-127 | Shadow of the City

First time they meet someone from a previous world. The 'enemy' this time are 'evil spirits' that will attempt to flood into the city on the full moon. Protagonists look deep into the history of the conflict for an alternative solution to end the war. They finalize new teammate.

Arc 7 c128-147 | Doomsday Run

What it sounds like. Go on missions for the researchers to end the apocalypse (and beyond!).

Arc 8 c148-169 | Bloody Hospital

A strange hospital full of terminally ill patients invaded nightly by

ghosts? This arc likes to play with illusions.

Arc 9 c170-194 | Interstellar Conflict

The conundrum on being on a human invasion force against the last planet of the Zerg.

Arc 10 c195-213 | World of Demons

Hellish teaching requirements! Magicians and Monsters Fighting together against each other for the sake of their shared world! Yes, it's just as contradictory as it sounds. I feel more complicated about this world after reading the ending because I realized the protagonists actions may have helped the will of this world to fix its broken rules. They may have literally saved a doomed planet. They were only a supplementary force at most for the researchers of the Doomsday Planet. In this world, they utilized the tools available to change the direction of the future with purely their own strength and ideas. Third teammate separates knowing he is not ready for the next world.

Arc 11 c214-236 | Peace in the Fairyland

Finale is a cultivation world. This world has both the most oppressive rules and the most free opportunities for the couple. The cultivation supplements most of their known knowledge. The world is hard but practically made for them. Indeed they soon find out that at some point the lord god eyed their talent and started hand picking the worlds they would enter. They find the truth behind everything and I think it's unique enough to be worth the read.

I am satisfied with the author, ending the story here. There is definitely a lot of room for the couple to keep moving forward and discovering new world and upgrading their own world and returning to visited world and maybe one day their relatives joining them one day after their natural deaths. The thing is that there is no further room for them to really upgrade within the system anymore. The formula of three worlds at each level is over. The pacing would be really f*cked up if the author forcibly continues beyond this. I think there is a reason why they return to the magic world was over and a few sentences. Additionally, I think they really hit their limit on creating new worlds. Anything beyond point whether it is an origin world or a marginal world would risk opening plot holes within the story due to unnecessary bloat. There are remaining questions but I think the author stops in time before they can ruin their own development. They end the story on a high note and I can't resent them for my own remaining curiosity.

We're introduced to SA immediately at the start of the novel. Shall we stop making saving women from abuse means to make the main characters look like a hero? That's strike number one. Then a fellow gamer like themselves is found severely SA-ed and abused and the first thing ML does is be annoyed at her distress? Like wowwww. And we're supposed to like him. I haven't read further but I bet there will be a part where she betrays them or smth just so the audience can stop sympathizing with her.
