Doomsday Life Simulator System In A Zombie Apocalypse World Update Era

{Mana Reservoir (Peak Crystal-grade Train Module Blueprint): Installed within the train’s core system. A high-capacity mana storage and regulation module designed to stabilize, store, and redistribute large amounts of energy for sustained operation.

Once installed, the module will continuously absorb ambient mana from the surroundings and store it within its internal reservoir. The stored mana can be used to supplement the train’s energy consumption, reducing fuel usage during prolonged travel or combat. It can fully substitute the usage of train fuel to power up the gadgets, machinery, and modules within the train.

Moreover, the Mana Reservoir will automatically supply energy to other train modules when their consumption exceeds the natural gathering rate, ensuring stable operation even under high-load conditions.

The storage capacity and absorption rate are significantly higher than standard energy modules, allowing excess mana to be accumulated over time. Stored mana can also be released in bursts to temporarily enhance the output efficiency of energy-based modules.

Due to its internal regulation system, the Mana Reservoir can stabilize volatile energy fluctuations, reducing the risk of overload or backlash when multiple high-grade modules are active simultaneously.}

{Materials Required: Crystal-grade Mana Conduit x80, Reinforced Energy Vessel x50, High-Capacity Storage Core x20, Advanced Circuit Matrix x15, Large Energy Core x3, Crystal-grade Enhancement Crystal x4, and Arcane Core Imprint x1}

[As soon as you saw the loot you obtained from the Crystal Chest, you immediately shared the notification you received with Jade and the rest of the train crewmates.]

[Receiving the notification, their eyes widened at how luxurious the treasure chest loot was.]

[They were further surprised after checking its item description, to which Astraea immediately exclaimed, "The Magic Blood Staff is mine!"]

[You, Jade, and Scarlet didn’t refuse since the magic blood staff suited Astraea better than the rest of you. After all, none of you specialized in blood-attributed magic aside from Astraea.]

[Astraea possessing the magic blood staff would allow it to show its full potential compared to if it’s in Jade, Scarlet, or your hands.]

[After you determined that no one planned to claim it, you immediately stated, "I’ll take the Crimson Ring of Lifesteal. Among us, I’m mostly the one fighting powerful opponents, so I’ll need it."]

["Moreover, even if you guys don’t have it, the Blood Harvest train ability is more than enough to grant the needed lifesteal passive effect."]

[Jade nodded, "Then you’ll have it, darling."]

[Aside from Jade, Scarlet and Astraea also nodded in agreement.]

[After all, Astraea already got the item she needed. On the other hand, while Scarlet coveted it, she knew that you needed it more since the health regeneration speed of humans wasn’t as good as werewolves like her or vampires like Astraea.]

[After all the items were allocated, Jade looked at the new train abilities and modules, and she couldn’t help but smile in satisfaction, "The Lifesteal Blood Bat Nest greatly improves our Zenith Train’s offensive capabilities as it’s a turret-type train module."]

["Not only that, compared to most turret-type train modules, it’s also very flexible since the Blood Bats aren’t just train bullets or projectiles but instead, function similarly to summoned creatures."]

["Moreover, the Mana Reservoir solves our problem of train fuel. While we don’t lack train fuel, it’s still better to have an alternative energy system aside from just train fuel."]

["We already have a lot of train modules and abilities. With the mana reservoir, we can instead use mana to power them up and just let the train fuel be used for train travel purposes only."]

["After all, as the train’s level increases and hits the 10 level milestone, the train fuel needed becomes higher in quality. The train fuel obtained from Gold Chests and below are no longer usable and acceptable, especially when our train’s engine has been upgraded alongside the rest of the train."]

["With the mana reservoir, we can even just use our mana to fill it up. The energy capacity of the mana reservoir is also greater than the train fuel tank, so it can easily replace our train’s energy needs."]

[You and Jade had encountered that problem before, but it wasn’t really a huge one since Jade could exchange for train fuel using her SSS-rank Equivalent Exchange innate talent.]

[However, it was a problem for most train conductors since even if they stocked up on train fuel, it would eventually become irrelevant and unusable.]

[For example, a train fuel at Level 1-10 would no longer be available when that train upgrades to Level 11. Due to that, you and Jade had changed train fuel twice, once when the train became Level 11, and twice when the train attained Level 21.]

[Of course, it wasn’t an "absolutely unusable" situation since lower train fuel grades could still be used.]

[However, there’s a reason why it wasn’t suggested. Not only was the energy efficiency extremely low, but there were also risks of the train engine stalling or even exploding, as well as the train going off-course and arriving at a different station world than what was planned.]

[Unless a Train Conductor was poor and didn’t have any better options, no Train Conductor would risk using train fuel of inferior grade.]

[Undoubtedly, the Mana Reservoir train module solved that problem, so you and Jade no longer have to worry about your train fuel not keeping up with the fast leveling speed of the Zenith Train.]

[Hearing Jade’s words, you nodded, "Aside from the Mana Reservoir and Lifesteal Blood Bat Nest, the addition of the Magic Thorns train ability also solved our train’s defense and durability."]

["With it, even if powerful enemies are attacking our train, not only will their damage be reduced by 30%, but that 30% of their dealt damage is even sent back to them, letting them get a taste of their own medicine."]

["With our turrets dealing with those small fries, the stronger ones among them won’t be able to last long since the stronger they hit, the more they are self-harmed by their own attacks."]

["Not to mention, the Blood Harvest train ability is like the Divinity Slayer ability, a type of train ability granting us, the train crewmates, buffs without even doing anything."]
