Ark Games: Agents Of Death

A hundred years after the nuclear disaster, the survivors huddled in the wasteland and looked up at the "Ark" - the Garden of Eden suspended above the radiation cloud. And I, Lu Yin, became its executioner.
The first rule of "Agent of Death": Create a perfect accident every day and clear one name. Rule No. 2: All killings must be broadcast live worldwide. Reward: In exchange for the potion that renews my sister's life every week.
I played the perfect killer for three months and reached the top three in the standings. Until yesterday, I discovered the secret of the "Damned People" list - the next target is the last vaccine researcher in the wasteland; and all the names next month are potential leaders of resistance to Ark's rule.
What’s even more fatal is that my sister pulled out her own IV tube. She looked at the live broadcast replay and said to me: "Brother, every time you save my life, you kill a hundred people who deserve to die."
Now, the whole Ark is looking forward to my "wonderful performance" tonight. Unbeknownst to them, I had gained access to the list backend. Tonight, when the global signal is focused on me again, I will no longer perform accidents -
I will live broadcast the death of the system to an audience of 700 million.
