Alien Zero 2: Purple Smoke Comes to the World

A star eclipse comes and Blue Star becomes purgatory. Zombies devour people and hunt for prey with abnormality. The once prosperous city turned into a hell on earth overnight. The virus is raging, order has collapsed, and humans are waiting to die in despair. Jiang Mochen, the illegitimate son of the Jiang family, one of the eight most aristocratic families in the imperial capital, He endured half his life in his previous life, reached the pinnacle of scientific research on his own, and developed the only agent that can suppress corpse poison-Purple Smoke. But he never thought that what he devoted all his efforts in exchange for was not redemption. It was betrayal, it was a frame-up, it was being pushed into the tide of corpses by the former "relatives" and colleagues, and no bones were left. The Purple Smoke achievement was stolen, humanity's last hope was extinguished, and civilization completely collapsed. Once reborn, Jiang Mochen returned to three months before the star eclipse broke out. There was no warmth in his eyes anymore, only a biting cold light remained. In this life, he no longer desires family affection, does not care about vain fame, and does not want to be a savior. Make purple smoke, master poison, build dead soldiers, and control power. To the enemy, eradicate the roots; To those who betrayed, repay them a thousandfold; In this world that regards human life as nothing, he brings darkness to the world. Since the world is already a purgatory, Then it will be up to me, Jiang Mochen, to rewrite this era of zeroing with my own hands.
