[’As an Arch Human, my life level is way above theirs.’]

[’Only the mortal lifespan crystal made from living beings of the same bloodline rank as me would increase my lifespan in a 1:1 ratio.’]

[’Otherwise, mortal lifespan crystals taken from living beings at lower bloodline ranks would have diminishing returns.’]

[It was also due to this reason that you never stopped exploiting them, as you could only make do with a higher quantity to make up for the lack of quality.]

[Aside from the harvest of innate talent crystals and mortal lifespan crystals, you and Old MacDonald had also successfully converted the Crystal Gem Fruit into a seed.]

[You both had achieved it last week, even going as far as planting that seed and letting it sprout into a Crystal Gem Tree.]

[After using Peak Crystal-grade fertilizers made from the corpses of Peak Crystal-grade Angels of Death, Old MacDonald managed to let it bear the fruits of Peak Crystal-grade Crystal Gem Fruits.]

[Since you only need one of them, it didn’t take long for it to be ripe and edible. After eating one, you’ve successfully added it into your food catalog, creating countless copies of it using Unlimited Food Creation (Gold).]

[After you gave several of them to each of your Train Crewmates, they’ve all become Peak Crystal rank powerhouses after eating those Peak Crystal-grade Crystal Gem Fruits.]

[Moreover, due to the stat boosts you all had due to your superior bloodline ranks, you and the others merely had the power rank of a Peak Crystal rank but had the stats and combat power of an Initial Mythril rank.]

[’With the current power of the Zenith Train Crew, we wouldn’t have been at a huge disadvantage if we fought the seven Mythril rank Angels of Death again.’]

[’They’re lucky that we needed their corpse to fertilize the Crystal Gem Tree. Otherwise, Old MacDonald and I could have already made the Crystal Gem Tree as soon as we got the fruit.’]

[’The only reason why we haven’t done so was due to a lack of fertilizer. But since that problem is solved, all that’s left is to fetch fertilizers of a higher grade. Due to this, Peak Crystal-grade Crystal Gem Fruits have successfully been mass-produced.’] 𝓯𝓻𝓮𝙚𝙬𝓮𝙗𝒏𝙤𝒗𝙚𝙡.𝒄𝒐𝓶

[’Now, the problem is to nurture the Crystal Gem Tree and let it evolve into a Mythril rank one. The fertilizers are high-grade enough, but to evolve the Crystal Gem Tree to Mythril rank, fertilizers alone aren’t enough.’]

[’From what my Hint Prompt had discovered, Crystal Gem Trees at Mythril rank are extremely rare, almost extinct. After all, Crystal Gem Trees are specifically a species of trees that bear crystal and gem-attributed fruits.’]

[’They’re trees that is specifically a resource for reaching Crystal rank. For it to also allow advancement to Mythril rank would be unprecedented.’]

[’The only reason why a few of the Mythril rank versions of the Crystal Gem Tree existed was due to the station world they were in being extremely high level, to the point that it forced the Crystal Gem Trees to evolve due to too much resources and nutrition.’]

[’Such Station Worlds possessed powerhouses at the Aether rank. To replicate the environment of a station world that is prosperous, it is beyond the capabilities of the Zenith Train Crew.’]

[’However, not all hope is lost. I still have World Order and Absolute Boundary. As long as I weaken the boundary of the Crystal Gem Tree’s evolution between Peak Crystal rank and Initial Mythril rank, I can then use countless Late Mythril rank fertilizers and force feed it with them.’]

[’With World Order being used to give it a boost in absorbing those fertilizers and ensuring its evolution, as well as Old MacDonald’s support from the side, it should be possible to achieve a Crystal Gem Tree at Mythril rank.’]

[Having that thought in mind, you didn’t leave the Ranch’s subspace with Old MacDonald yet. Instead, you went to do a trial and error with him in letting the Crystal Gem Tree evolve.]

[Several days soon passed. During that time, the Extreme Cold Extreme Event had ended.]

[However, there weren’t that many Terran Train Conductors that died within your region. After all, they all received your products, which allowed them to survive the Extreme Heat and Extreme Cold at the expense of being indebted to you.]

[So, although the majority of them didn’t die, those who didn’t had become your debtors. It was to the point that those who didn’t become your debtor in the region were extremely rare to find.]

[Since you were busy experimenting with Old MacDonald, the Loan Shark’s Ledger was completely handed to Jade so that she could manage the debtors and collect their collateral if the ledger ever discovered that the interest became too high for them to pay.]

[After the Extreme Cold Extreme Event ended, what followed was the Eternal Night Extreme Event.]

[The Eternal Night Extreme Event made it so that every day would be shrouded in the darkness of the eternal night. Because of that, dark-attributed creatures and races would become somewhat stronger, like Astraea, Scarlet, and Morvane.]

[As for creatures and races that were light-attributed and were dependent on daytime, they all became weaker.]

[Undoubtedly, as humans who were mostly active during the day, it wasn’t looking good for the Terran Train Conductors who hadn’t changed into other races yet or evolved into Arch Humans.]

[As for you and Jade, who had evolved into Arch Humans and possessed the Adaptive Evolution innate ability, the two of you could easily handle the pitch-black night and adapt to it.]

[Due to that, even without using magic, you and Jade naturally adapted and gained night vision, easily treating the Eternal Night as if it were still daytime.]

[Jade and your combat power during the Eternal Night were not only weakened, but it had even become stronger and received the same buffs as dark-attributed races like Scarlet, Astraea, and Morvane.]

[Not only that, the previous two Extreme Events seemed to have caused the overall population of the Terran Humans to drop drastically.]

[After all, the human race wasn’t suited to survive in extreme temperatures that were even worse than Terra’s South Pole’s cold temperature.]

[Because of that, a regional merge happened again, but this time, every region was merged until each region had an average of a million Train Conductors.]

[Aside from merging regions, the Terra World Chat Group was even implemented, allowing Terran Train Conductors to communicate with other Terran Train Conductors from other regions.]

[It was no longer restricted to simply the region the Terran Train Conductors were in.]

[After you had received that world announcement, you immediately thought of exploiting those Terran Train Conductors from other regions.]

[Due to the lack of Terran Train Conductors, as you were restricted to communicating only within your region, you couldn’t acquire that many debtors. It made discovering SS-rank and SSS-rank innate talents a lot more difficult.]

[Most innate talents you’ve encountered were quite useless, so you had only resorted to placing the lifespans of those worthless debtors of yours as collateral.]

[But for those low-ranking innate talents that had some potential if they could be raised in rank, you still acquired and kept them.]

[You might not be able to make use of it now, but you figured that as long as you could find an item that could increase the rank of innate talents, those low-ranking talents would soon become useful.]

[After the Terra World Chat Group was implemented, the trading market had also expanded and had been split into two markets. They were the Regional Trading Market and Terra Trading Market.]

[When you performed a quick browse through the Terra Trading Market, you were quite surprised that there were Gold-grade items up for trade, and from the looks of it, there was a Terran Train Conductor that had reached Gold rank.]

[From your estimation, that shouldn’t have been possible normally. After all, most Terran Train Conductors were at Iron rank, and only a minority with functional innate talents or great luck would be at Bronze rank.]

[Due to that discovery, you realized that you shouldn’t underestimate these Terran Train Conductors. Just having a decent SSS-rank Innate Talent would allow them to achieve a growth speed faster than your estimation.]

[Although you were interested in knowing more about the strongest Terran Train Crew aside from your Zenith Train Crew, you and Old MacDonald were still way too occupied with nurturing the Mythril rank Crystal Gem Tree, so you didn’t pay more attention to it.]

[After the implementation of the regional merge and Terra World Chat Group, a few more days have passed.]

[Finally, you and Old MacDonald had not only allowed the Peak Crystal rank Crystal Gem Tree to evolve to Late Mythril rank, but even produced one Late Mythril-grade Crystal Gem Fruit!]

[With the successful production of the Late Mythril-grade Crystal Gem Fruit, you immediately ate it and added it to your food catalog.]

[Afterwards, you created countless duplicates of it. After sharing it with all of your train crewmates, the Zenith Train Crew has officially become Train Crew with Late Mythril rank powerhouses!]
