Project Relife: 2x Isekai System

Dear Xin, Nyaa~~~ I hope you are fine. I think it's your first day on earth. I wish you success in your revenge. And hope this time the world won't get destroyed like the last time. Since there is a charge on the number of characters I am using right now, I am keeping it short and simple. The last time the magical world got destroyed, we tried to reverse time and send your soul there. But due to some unforeseen circumstances, we were unable to do so. Since trillions of souls were on the line, we decided to merge your earth and the magic world into one. We have successfully planted the magic world's characters on your earth, and for magic, we will add it within a month. Hope you enjoy your stay there. Nyaa~~ Itsuki out~~~

Pleistocene

Definition of the base of the Pleistocene has had a long and controversial history. Because the epoch is best recognized for glaciation and climatic change, many have suggested that its lower boundary should be based on climatic criteria—for example, the oldest glacial deposits or the first occurrence of a fossil of a cold-climate life-form in the sediment record. 

Other criteria that have been used to define the Pliocene–Pleistocene include the appearance of humans, the appearance of certain vertebrate fossils in Europe, and the appearance or extinction of certain microfossils in deep-sea sediments. These criteria continue to be considered locally, and some workers advocate a climatic boundary at about 2.4 million years.

Pre-Pleistocene intervals of time are defined on the basis of chronostratigraphic and geochronologic principles related to a marine sequence of strata.
