Just like the All Secrets Order, just like Ossana's family, who poured all their energy into researching Fantasy Species, each side has something worth taking from.
"We spent nearly a century and made countless sacrifices to carry out a complex 'cultivation' of the Fantasy Species. By now it should be called a Fantasy Tree instead. After a series of intricate transmutation rituals, we can turn High Tier Condensers into nutrients, feed them to the Fantasy Tree, replenish the Fantasy Species' depletion, and bring forth new fruits."
Bologue thought it over and felt that Ossana wasn't lying. The Fantasy Species is just the ignition point; to actually fulfill wishes still requires a multitude of prices to be paid. Just like what Aimou did back then: in that final scramble of the timeline, she couldn't withstand the Fantasy Species' drain on her own body and nearly died in the past.
