Countdown to Doomsday: I Use Cards to Protect My Sister

His parents died young, and his sister Lin Xiaoyu is Lin Mo's only weakness. In the last ten years, he struggled like a wild dog, just to let Xiaoyu eat more food and avoid the cold. He thought he could protect his sister by being humble enough and working hard enough. Until that day, the acid of the third-level monster "Corrupted Dragon Lizard" melted the last line of defense of the base, and he watched Xiao Yu being swallowed up by the collapsing ruins... When he opened his eyes again, Lin Mo returned to three days before the end! Looking at the dazzling countdown on the calendar on his mobile phone, he was almost torn apart by the huge fear and the ecstasy of regaining it! "Three days! Only three days!" "Xiaoyu... This time, I will let you live even if I give up my last drop of blood!" Stock up on supplies! Compete for cards! Build a survivor base! He must race against time before order collapses! When the collision crack tore the sky apart again, the earthquake shook the earth, and the monster crawled out of the crack with a roar, the young man named Lin Mo had already taken his sister and hid in a strong stronghold, clutching the most precious blood-stained cards from the early days in his hands, his eyes tired but as cold as iron. "In this life, I don't want to be king, I just want to protect you. Whoever dares to touch Xiaoyu or rob us of our livelihood, no matter whether you are a monster or a human... I will fight with my life until death!"
