The End of the World: at the Beginning of the Game, All the School Beauties and Sisters Are Tied to the System.

[End Times] + [Harem] + [Multiple Heroines] + [Invincible] + [System] Ash Day has arrived, and the world has entered the "Dimension Ascension Era". Zombies break out, civilization collapses, the world is updated every fifteen days, and monsters, awakened ones, and ecological disasters all evolve crazily. And Ye west, on the first day of the apocalypse, was bound to the "apocalyptic pure love harem system". As long as you capture high-quality heroines who are pure in body and mind, you can gain points, materials, future technology, and even awakening abilities! So—— The cold-hearted and sinister senior sister from the student union began to sneak into his arms in the middle of the night; The arrogant white-haired female brat with a poisonous tongue scolded him as a pervert while grabbing him tightly and refusing to let go; The yandere Qingmei stares at the woman who appears next to him every day; Bingshan's adopted sister is cold on the surface, but secretly she just wants to monopolize her brother; Gentle counselor, wealthy daughter, female CEO, female military officer, beauty from the scientific research bureau... Others are chewing the bark of trees in the last days. Ye west was chased by a group of top beauties. While other survivors are still fighting for a piece of bread, Ye west has already relied on the system to build his own doomsday harem and survival empire?
