*** Please Vote for my book so I can push it out **** Go read my other book Deadman Apocalypse. As disaster was about to strike, every human aged 18 to 59 was transmigrated into a desolated world and challenged to a game of survival. From terrifying acid rains to endless natural disasters, the heavens burn while the earth scorches. Radiation is rampant, and nobody is spared from the dangers of this hellscape. The only way to survive is by building a shelter and slowly upgrading it in hopes of making it through another day. Luckily, Sun Han awakened a Doomsday Survival System that allowed him to infinitely level up and upgrade his shelter! The main wooden shelter door could be upgraded into a metal door, which in turn could be upgraded into a composite gate. Wooden spears could be upgraded into bronze spears, eventually becoming electromagnetic spears... While everyone struggled to survive, Sun Han was fully loaded and well-equipped to dominate the post-apocalyptic world. "While some of us are lighting oil lamps, he's been using refrigerators!" "The walls of his shelter alone are tens of meters thick. It's the safest place on this planet." "Before I die, I wish to spend one day in his shelter..." And the planet is 100 times bigger than Earth. When they get teleported, a system shows their status screen, displaying their personal information and inventory, which only includes a level 1 underground house or a house on land.
