Tomorrow War: Awakening

The protagonist accidentally went to the world of 2155 and found that the technology of that world was even more backward than that of 2010. The reason was the abuse of certain technologies, which led to a great technological recession. Not only that, all the species that had ever appeared on the earth were resurrected, and they became violent with mutations. In order to survive, human beings have built several huge shelters and built thick walls to resist the attacks of these beasts. This novel and its characters are purely fictitious.
