You Made Me Drink Nuclear Wastewater, So I'll Steal Your Billions in Supplies in the Apocalypse

In his previous life, Zhou Wuyang was tricked by Yan Xiaoyu into drinking radioactive wastewater, leaving him in agony in a hospital bed for five years. When the apocalypse came, Yan Xiaoyu took him away to study his life force, cutting off pieces of his flesh and drawing his blood every day.

After being reborn, Zhou Wuyang knew the apocalypse was coming. To stockpile supplies, he told Yan Xiaoyu about the impending end of the world in advance.

Once Yan Xiaoyu had gathered supplies, Zhou Wuyang, who had already activated the Immortality System, not only slaughtered Yan Xiaoyu's entire family but also took every last one of their supplies.

After that, Zhou Wuyang began to build up his strength, determined to erase from the world map the country responsible for dumping radioactive wastewater.
