I Am the Guardian God of Humanity

When a Level 10 sea beast codenamed Taotie obliterates Huaxia on New Year's Day 0262, war god Chen Feng is given a second chance—reborn eleven months before the apocalypse. Armed with foreknowledge of the coming catastrophe, he must convince the nation's leaders to build an iron Great Wall spanning 20,000 kilometers of coastline. As sea beasts ravage America, the Northern Bear Nation, and beyond, Chen Feng races against time to forge humanity's last bastion. Foreign powers once mocked his vision; now they beg at his gates for sanctuary. The world is drowning in blood—but the East will stand.
