Ji Ran traveled to the Collapse World. In this world, which was extremely hostile to men... well, humans, Ji Ran felt a little panicked. However, after obtaining the [Dungeon System], he felt that his survival might be somewhat guaranteed. However, there were two options for the dungeon. The first was to clear the dungeon alone. This was too difficult, so he skipped it. Even if one person buffed the player, he still had to skip it! The second option, while the system's buffs would be weakened, would randomly match players with other players. So... Kiana: [Huh? This world actually has so many fun things?] Alicia: [Hehehe, it seems I'm popular elsewhere, too?] Bronya: [Is this a new game? Okay, Bronya accepts the challenge! Watch Bronya clear it with one life!] Raiden Mei: [I'd like to ask, this dungeon allows me to become stronger and control the power of the Herrscher Core by increasing my natural strength, right?] Mei Raiden: [What the hell is this Shenzhou home cooking 300-style dish? (╯‵□′)╯︵┻━┻]

[Slice of life][Multiple female protagonists][The protagonist will become a guardian of the guardian][No system but a Heroic Spirit][The skills and Noble Phantasms reflected in the legends from Earth are equally applicable in Honkai Impact 3rd][There may be a future collaboration with Hanabi in Honkai Impact 3rd]

In another timeline, Earth is invaded by alien life. A child chosen by Alaya, an ordinary person, gains the light of a heroic spirit and saves the world. After the timeline restarts, he lives a peaceful and ideal life. However, in the real world, Gaia awakens him again, and he enters the Honkai Impact 3rd world for further study to help Earth escape the prison of observation. The main storyline focuses on daily life in the Honkai Impact 3rd world, with minor climaxes occurring in the Immortal Ship Luofu.

March 7th: Li Xin, you're too amazing!

Xing: Coach, I really want to learn this! I'm willing to do anything!

Danheng: No matter what difficulties your hometown encounters, I will help you, because we will be working together as a train crew for a lifetime.

If the synopsis is insufficient, please proceed to the main text. As a novice author, I hope to write some stories that bring joy to readers.

Tips for reading the article: the main perspective will be [Captain] + [Kiana] + [Civilization in the first half] + [Daily life after the collapse in the second half]

Not a title scam!!

The pace was very fast, and it collapsed after about 80 chapters!!!

In the previous era, he was the [Night Watchman] of the beginning, and in the present era, he is the [Lamp Bearer] of the end. The boy who was born because of the concept of [Captain] once cut off his [past], [present], and [future].

If the life of K423 was a stage set by Otto, then the existence of the boy seemed to have been arranged by fate.

From the moment the [Lightkeeper] and the [Night Watchman] met, a plot spanning two eras slowly unfolded.

A Jesus-style self-sacrificial salvation begins to come to an end, but can you be sure that is what they want?

The boy looked at the flying Hyperion and felt that everything seemed unimportant. Finally, he left a sentence...

Finally, please allow me to once again state the significance of my appearance in this world...

[Day 1 of the time travel: Wearing Adi King's battle suit and dark red hair, is Emiya Shirou actually me?]

[Day 3: Confirmed, this isn't the UBW questline, no Red A experience packs, so I'll have to rely on myself to master Unlimited Bladework.]

[Day 20: Strengthened my magic proficiency and began practicing Projection. During this time, I met an alchemist who asked me where I got all these alchemical weapons made from recycled metal.]

What the hell is recycled metal?

[Day 90: Finally mastered my first Noble Phantasm, Projection. They exclaimed, "This is the Seven Kingdoms," an outstanding achievement in alchemy."]

Huh? I don't really understand you alchemists.

...

[Day xxx: Huh, I finally mastered Unlimited Bladework! Their expressions were fascinating, and they asked where the Nibelungen was.]

How come you don't even know about the inherent barrier? Isn't this... Type-Moon!?
