[You weren’t worried that the Dravenhart Clan would refuse Astraea’s "request".]
[After all, no matter how important those books were, they weren’t as important as the possibility of offending a Pureblood Vampire. Moreover, by virtue of Astraea’s higher bloodline rank alone, they wouldn’t have been ecstatic if she had volunteered to become the Dravenhart Clan Leader.]
[Unfortunately for them, they were too blind to see Astraea’s potential, and so, they didn’t treat her that well when she was at her lowest.]
[So, it would be wishful thinking on their part that Astraea would even care about them now that they would start sucking up to her when she’s currently at her highest.]
[You knew that it was only due to Astraea not being an ungrateful swine that she didn’t decide to cause genocide to the Dravenhart Clan and planned to even make it the only royal vampire clan overlord in this vampire continent.]
[Otherwise, if she hated them and didn’t care about their past spending on her, she wouldn’t have suggested to massacre the Bloodthorne Clan and instead, suggested to slaughter the Dravenhart Clan.]
[After you made your decision, Astraea didn’t refuse and nodded in agreement, "We’ll go with that plan of yours. The two of us should be enough to deal with those royal vampire clans."]
["Jade, Scarlet, and Old MacDonald will be left to guard the train. I will be in charge of killing those vampires while you’ll just be at the side, assisting me with taking and storing the things we’ve plundered."]
[Hearing Astraea’s words, you nodded, "I’m fine with that. As much as possible, even I don’t want to offend the Vampire Progenitor."]
["He’s the strongest existence we’ve ever encountered, and I don’t want the Zenith Train Crew offending a Peak Celestial rank Vampire Progenitor just for these mere Diamond rank Vampire Ancestors."]
[After you and Astraea agreed on that, Jade and Scarlet didn’t refuse, while Old MacDonald wouldn’t care about the usual operations of the Zenith Train Crew and would only participate in extremely important ones.]
[After letting Jade handle the Train Conductor Authority operations while you were away, you and Astraea left the Zenith Train and stepped into the Millennium Vampire War Station.]
[Taking out your Absolute Compass, you commanded it to find the nearest royal vampire clan, excluding the Dravenhart Clan.]
[Needless to say, a day has passed since you and Astraea set off for those royal vampire clans.]
[You had successfully plundered the hundred thousand years of heritage and relics of those royal vampire clans. Even the Dravenhart Clan wasn’t spared, as only their lives were spared, but their books and treasures weren’t.]
[Aside from duplicate treasures that you’ve already obtained from other clans, you’ve taken the new and unique ones from the Dravenhart Clan and only left them with the treasures you’ve already had.]
[Even if they wanted to complain, they dared not. Especially after they discovered that Astraea had caused genocide over the rest of the royal vampire clans, they didn’t dare to show any resistance and were even the ones who willingly offered entry to their royal library and treasury.]
[Due to that incident, it made you realize just how important power was. You could lack everything, but lacking power and being weak was a sin.]
[After you and Astraea visited the Dravenhart Clan and the Dravenhart Clan gave "sponsorship", the two of you have already returned to the Zenith Train.]
[With the magic books already collected, you and Jade, along with the rest of the train crew, spent five years in the Bloodthorne Clan’s Inverted Tower, an equivalent of five days outside.]
[After you and Jade researched magic in seclusion for five years, both of you, as well as the rest of the Zenith Train Crew, became Eight Circle Mages!]
[Jade and your research progress on the Eight Circle Magic spells were already achieved since the first year of your seclusion. The rest of the four years were to develop more magic spells that were suitable for each of the train crewmates, as well as the time it took to master them.]
[After successfully becoming an Eight Circle Mage, you even managed to create magic spells at Seven Circle that didn’t require mana. Those magic spells were modified for Scarlet’s sake since she didn’t have mana on her.]
[Instead of mana, you replaced the energy needed with blood energy, using the Bloodline Magic that Scarlet possessed as a bridge that allowed her to have a connection with the magic power system.]
[However, blood energy alone wasn’t enough, so you added spirit energy into the mix, allowing the combined energy system to mimic the "magical" properties of mana to some extent.]
[After five days in the outside world had passed, you had used Station Dwell Time Extension tickets thrice just to let you and Zenith Train Crew linger in the Millennium Vampire War Station.]
[Fortunately, with the end of the Zenith Train Crew’s Five-Year Magic Research and Training, you no longer intended to stay in the Millennium Vampire War Station, so you used your Train Conductor Authority to depart.]
[As soon as the Zenith Train departed and left the Millennium Vampire War Station, you and the Zenith Train Crew soon heard a notification sound in your minds.]
