Doomsday Life Simulator System In A Zombie Apocalypse World Update Era

[Hearing your assurance, Jade no longer worried and instead, focused on exchanging for the unobtained train upgrade materials using the Heavenly Essence you had given before.] 𝓯𝙧𝓮𝓮𝒘𝓮𝙗𝙣𝒐𝒗𝒆𝓵.𝓬𝓸𝒎

[No longer caring about using up all the Train Cores she had, Jade continued upgrading the train to her heart’s content, until the Train Cores ran out first.]

[Her energy was still abundant, yet what gave out first was the Train Core supply. However, it wasn’t without result as the train had been upgraded from Level 21 to Level 25.]

[With the train being successfully upgraded to Level 25, the delayed world announcement soon resounded.]

[-Ding!]

{World Announcement: Train Conductor Duo Zayne Voss and Jade Willows’s Zenith Crew has completed an unprecedented achievement of being the first to upgrade their Train to Level 21!} x3

[-Ding!]

{Train Conductor Duo Zayne Voss and Jade Willows have received the following rewards for completing a world achievement: Train Ability: Train Synchronization, Platinum Chest x1}

[’Only this much? Don’t tell me a Level 31 Train would only yield a world achievement reward of one Diamond Chest.’]

[As your power rank became stronger, most items that used to be really powerful were tasteless to you now.]

[Compared to the Platinum Chest, what you valued more was the Train Ability: Train Synchronization.]

[No matter what, some items might no longer be able to keep up with your progress, but the train ability definitely won’t, as long as the trains keep on being upgraded. After all, the power of a Train Ability, in most cases, relied on the level of the train.]

[Although you complained about the meager rewards granted by the world achievement, Jade was already satisfied with it since it was better to have something than nothing.]

["Darling, our world achievement caused a commotion in the region chat group again. Especially when some of those Train Conductors who were relocated into our region found out that we were in this region."]

[Hearing Jade’s words, you merely shrugged, "Well, it doesn’t matter since they’ll still have to die if we encounter them due to the extreme event. In my eyes, they’re just walking innate talents and train cores."]

[Jade nodded, "That’s true. Especially Train Cores, we desperately need them or else we can’t close the gap between those veteran train conductors."]

[The discovery of the existence of veteran train conductors still had Jade worried.]

[Although she didn’t mind their existence as that meant there would be more resources to plunder, there’s still the possibility of capsizing and being liquidated after encountering those that you and she couldn’t defeat.]

[While Jade and you were confident about the Zenith Train Crew’s combat power, you both didn’t let it get to your head, especially after knowing that there were unfathomable Wild Gods residing in the forsaken past at the Endless Barren Wasteland.]

[Jade and you knew that the Zenith Train Crew wasn’t invincible yet, so being cautious and prepared was a must. In some ways, due to the existence of the forsaken past, the veteran Train Conductors didn’t seem to be that much of a problem.]

[After you and Jade opened the Platinum Chest, you and she were disappointed that there wasn’t anything useful obtained from it aside from a Train Carriage Modification Blueprint called "Training Ground".]

[Needless to say, you and Jade immediately used it and set it up on Carriage 5. The materials used to create it were easily submitted by Jade.]

[With the Training Ground Carriage, you, Jade, Scarlet, Old MacDonald, and future train crewmates could use it for training or sparring.]

[’Since it’s a training ground, it also has its perks. Aside from just having the space and field to train and spar, I’ve also noticed that the time flow control within the Training Ground Carriage is more than the other carriages.’]

[’If I can only control the time flow of other carriages in a 2:1 ratio by default without expending too much Realm Energy, the Training Ground’s default time flow control ratio is at 4:1.’]

[’In other words, a week passing by outside the Training Ground will be 28 days in the Training Ground, almost a month. And if I open a subspace within the training ground and move the master bedroom there temporarily...’]

[As soon as you started thinking about lewd thoughts, you shook your head and lamented that Jade had truly led you astray.]

[After you and Jade opened the Platinum Chest and received those mostly mediocre rewards, you soon checked the description of the Train Ability: Train Synchronization using Train Conductor Authority.]

{Train Synchronization (Ability): The Train Conductor or anyone permitted by the Train Conductor can synchronize with the train. During the synchronization, the user can decide on which part to synchronize their power with the train.

If they chose speed, the speed of the train will be proportional to the user’s speed. In other words, if the user’s speed is at the speed of light, then even if the train hasn’t reached that speed yet, the train will move at that speed.

During train synchronization, the user can also choose to control the train as if it’s an external manifestation of their body, similar to piloting a mecha. Moreover, be warned that during train synchronization, the train will now run on the user’s energy rather than train fuel.}

[As soon as you finished reading the ability description of the Train Synchronization, you realized just how powerful and convenient it was.]

[Although using it would put a burden on the user, as instead of train fuel, the train would run on the user’s energy during train synchronization, it was a small price to pay.]

[’In the real world, I can already move at Mach 100 and circle around Terra in just approximately 20 minutes, and that was when I was holding back.’]

[’Since my power is now higher than my real-world self, I should be able to move faster, and the train can naturally move at the same speed as mine, no longer being restricted by its inherent train speed.’]
