Doomsday Life Simulator System In A Zombie Apocalypse World Update Era

[’The cooldown of SSS-rank Future Diary innate talent was one usage per week. So far, I don’t think I’ll last longer than a week here, so it’s best to make use of it now than later.’]

[’Moreover, while Kyle would make use of the Future Diary to check whether they’d die or not, it’s unlikely for me to die with my current power. So, the best use of Future Diary is to check whether my plans are viable.’]

[Adhering to the idea that "it was better to be safe than sorry", you decided to summon the SSS-rank Future Diary.]

[After summoning the SSS-rank Future Diary, a diary appeared in front of you, floating in the air for a while before it fell.]

[Catching the future diary, you checked it, and on the cover, it was titled "Zayne Voss’s Future Diary" with a handsome cover picture of you standing atop the corpses of the vampire participants.]

["Interesting, so aside from the one-page diary entry, the diary’s cover will also display my highlight scene in the future in the form of a 4k image."]

[With that discovery, you were quite satisfied.]

[Although it wasn’t much, every bit of information was valued by you. After all, such information came from the most probable future, so it was worth a lot.]

[After admiring your highlight scene photo, you decided to open the future diary.]

[Since it was your first future diary entry, your diary entry was written on the first page.]

[If one were to see the diary entry, there was one thing amiss about it. It was none other than the text size!]

[One of the limitations of the future diary was that one usage of it would only display the most probable future within a week. And another limitation was that such information could only be written on one page!]

[In other words, to condense as much information as possible, it was best to make the diary entry texts as small as possible.]

[Even with that in mind, most people would only be able to write 1cm text size diary entries. However, you weren’t limited by pen tip size and ink.]

[You had recalled that when you were slaughtering Spirit Avatar Masters in the Spirit Avatar Battle Station, you had found a spirit artifact that was in the form of a pen.]

[The ability of that pen was quite useless, as it captured the most useless first spirit avatar ability. It was none other than the ability to write sentences whose text sizes can be as small as a nanometer!]

[In other words, its only limitation was that if one were to use it, the text size must not be too small to make it unreadable.]

[In your case, with your eyesight as Peak Platinum rank Arch Human, a text size of a nanometer was not much different from that of a meter.]

[So, your future self dared to write it in 1 micrometer!]

[As for why it wasn’t in nanometers, it was due to the diary entry being quite small in content.]

[Your future self didn’t have much to write, and writing in 1 micrometer couldn’t even fill half of the page. Writing in nanometers would undoubtedly be overkill.]

[With that in mind, you decided to read your first page diary entry.]

/Day 1: Jade and I had decided to commence with our plan. It was completed yesterday, and now, we have caught all of the vampire participants. No matter how much they hid, they couldn’t escape the Absolute Compass’s tracking./

/Day 1: There were no problems when we kidnapped the vampire participants. As I had expected, these vampire participants wouldn’t make any waves as their trump cards weren’t as good as a veteran Train Conductor’s./

/Day 1: It might be unnecessary, but for my past self’s sake, I’ll write all the Bloodline Magic and trump cards they possessed. Their Bloodline Magics are... (omitted)/

/Day 2: I had locked up all the vampire participants I kidnapped in the training room carriage, specifically a hidden subspace in the Bloodthorne Clan’s Inverted Tower./

/Day 2: I didn’t kill any of them when I was kidnapping. So far, there weren’t any problems, so the rest of the train crew and I decided to kill them all at once./

/Day 2: All of the vampire participants have now died except for Astraea. With Astraea the only vampire participant left, she undoubtedly became the vampire champion of the Millennium Vampire War./

/Day 3: The Bloody Grail didn’t appear yet. According to Astraea, the blood of most of the fallen vampire participants must be released to the outside world and cannot be stored or sealed./

/Day 3: Listening to Astraea’s suggestion, I used Blood Manipulation to let the blood of the vampire participants be released to the outside world. I had used Train Conductor Authority to temporarily open up a portal that led from the training room carriage to the outside world./

/Day 3: After I released all the blood of the vampire participants, I withdrew control over them, and they seemed to be attracted to the sky./

/Day 3: The blood was pulled into the sky, and an illusory blood-stained golden grail appeared. It was none other than the Bloody Grail. It appeared to absorb all the vampire participants’ vampire blood./

/Day 3: Unfortunately, from what I discovered, the vampire blood wasn’t enough to activate the Bloody Grail. So, I headed to the Sanguine Clan, one of the eight royal vampire clans./

/Day 4: I’ve successfully slaughtered the Sanguine Clan. None of them were alive, and I didn’t spare any of them, reenacting the Bloodthorne Clan Genocide Incident./

/Day 4: Knowing the lack of blood devoured by the Bloody Grail, I didn’t store and hoard the blood those vampires spilled this time. Letting the Bloody Grail devour all of it, I discovered that the Bloody Grail started shining with a crimson light./

/Day 4: This is the accurate process of the Sanguine Clan Genocide, I’ve decided to note everything here even if it’s not needed, just so that my past self will be able to follow the future accurately... (omitted)/

/Day 4: After the crimson light shone brightly, the Bloody Grail was finally complete!/
