Entering the Apocalypse with Warehouse Space

It was an unusual year. When people thought that the Mayans' doomsday prediction of 2012 was an unrealistic lie, little did they know that hundreds of thousands of ancient civilizations that had disappeared from the earth had returned to the earth. Plagues, climate disasters, mutant zombies, and alien life species domesticated by "them" will all become common enemies that threaten contemporary human life. At this time, Xing Xiaofeng was heartbroken. The reason why he collapsed was not that the end of mankind was coming, but because he had just completed his destiny of saving mankind from the doomsday world of the parallel dimension, and he had just returned to save his homeland. Fortunately, he has his own life-saving system, which is called an energy synthesis warehouse... As long as there are energy crystals, he can synthesize everything he wants in this independent warehouse space. It seemed he could only save his home once more.
