Apocalyptic Fortress: I Can Infinitely Upgrade My Shelter

Apocalypse+System+Infrastructure+Shuangwen The apocalypse is coming, zombies are running rampant, and human beings have awakened their special powers and are desperately trying to survive. Lin Bei woke up... A ​​broken wooden house. Others' abilities are thunder and flames, and his "shelter system" is ridiculed by everyone as a garbage talent. The captain robbed him of his supplies, kicked him out of the team, and left him to die among the corpses. No one thought that this broken wooden house could automatically kill zombies, swallow energy, and be infinitely upgraded. Wooden house → villa → concrete fortress → war fortress → floating base → steel city. While others were still searching for cans in the ruins, Linbei already had clean water, endless electricity, and an automatic turret array. "This is my house. Showing up uninvited is considered an intrusion." When the former captain was nailed to the ground, he finally understood who was the waste. Besieged by a zombie wave, he used a fortress to defeat three thousand zombies. The alliance was dictatorial, and he single-handedly refused to recruit. The S-class zombie king was born, and he ushered in a new era of cleansing the apocalypse with a little zombie that could shout "hungry". When floating headquarters all over the world surfaced, the mastermind behind the scenes was horrified to discover: The dilapidated wooden house back then has turned into a... Steel city suspended above the clouds. "Uninstall the system? No. This world still needs a shelter."
