Rebirth at the End of the World: My Sisters Are a Bit Strong

[Apocalypse + Rebirth + Ability + System + Country] Reborn a year before the doomsday, Song Jiu returned with the memory of death and plant-type powers. The good news is that her four sisters of life and death have also been reborn, with metal, wood, water, fire, and earth, and five colors of superpowers. The bad news is that world-destroying natural disasters and zombie viruses are still on the way, and behind all this, there is actually a shocking conspiracy of the enemy country. This time, they are no longer alone. Bind the Tsundere system, contact the state machinery, seize opportunities, and hoard supplies. When the doomsday bell rings again, they are already holding sharp blades and possessing unique skills, standing on the ruins. Song Jiu: "Sisters, in this life, we have to save our lives by ourselves! We will protect this land." [In this life, our backs will be left to each other]
