I Am Swallowing Evolution in the Abyss

A tall tower stands on the glacier in the far north, reaching straight into the sky. No one knows how many floors it has, and no one knows why it appeared. The world calls it the Tower of the Abyss. Affected by the Abyss Tower, different levels of Abyss Tower teleportation nodes appeared in various regions, and a very few of them were connected to the unknown world. Young man, while you are staring at the abyss, the abyss throws a dog's head at you and gives you a middle finger.
