[One Week Before the Present Timeline]
On the borders of the Demon Ancient Empire, there is a convoy that consists of eleven black carriages traveling south with forty cavaliers clad in black masks and a flying holy fleet. They enter the now dark jungle that emits a weird aura like the forest itself is alive and watching the convoy. The dark tall trees gave way to the convoy because there is no road to Demon Ancient Empire but the Demon Empire did not take this as a negative effect and used this forest as a natural defense against invaders because the forest itself attack whoever invades or trespass the Empire.
The Overlord Warriors and their mounts saw in the distance large shadows like a giant, sitting on gigantic chairs looking at them. They are just looking with their white glowing eyes and their whole body is covered in a dark shadow. Ainz is fascinated by the said creatures but doesn't have time to entertain his "collector trait" thus he ordered his escorts to just pay them no heed. 
Inside the Carriage has a feature that can illuminate light to a specific place. The papers that are on the foldable table attached to the walls of the carriage are being signed by him because he doesn't have anything to do so he starts to look at the progress of his Empire
(This is so fast! The Empress of the Ancient Empire of Abnu and Acadia are finalizing the papers to be the second vassal of the SCE. The precise details of the Alliance of Yovaria Empire and Sorcerer Celestial Empire are finished. The mass production of the new Airships is being created in the Atlas Shipyard located on the tenth floor. The enlisting of soldiers outside the Capital City is starting, many sign up and will train for four years. The currency of the Empire is now fixed and all Yggdrasil coins are replaced by the currency of the Empire called "Chrono". All businesses have fixed prices supervised by the Merchant Guild.  This is so fast but all are now stable.) He mentally sigh and sign all papers.
(Well all of them are for the good of the Empire) He nod and continue signing while Satan is helping him by giving him the papers that he needed to sign, while Shub is just looking at him on the whole trip, not talking just staring. That's why he is thankful that Satan is here.
When they enter the jungle he immediately feel the faint presence of demons in the area. The animals here evolve, as the demon aura is everywhere in these lands as such every animal offspring here absorb the demon aura and became new species of demons called wild demons. They became bigger and more aggressive, the previous herbivores who only eat plants are now carnivores that hunt prey like any wild demons here.
This phenomenon became worst as the plants absorb it too and the plants here are poisonous or eat animals that's why typical plants where living beings can eat without being poisoned are extremely rare in this domain.
(How can they eat something like this?)
"The plants are rich in demon essence hmm, just like home" Satan spoke up as he glance outside and go back to giving him the papers and preparing the tea that came out of nowhere
[The Demons prefer to eat that has a demon aura on it because if they eat it, their energy will restore much faster, a preferred method but hard to produce because the way plant or an animal to become a "Demon" it required of long exposure to demon aura. In Yggdrasil, it didn't have this "Rule" on nature but there are some worlds like this master and I think that the rules in other worlds are starting to merge.]
