Do I Regret Becoming the Savior?

[Single heroine·No harem] On New Year's Eve, eight billion people around the world simultaneously received a one-way ticket to hell. Only I can see it. The bloody sky has fallen, and the era of regret has begun. If you sell your regrets, you can get rich overnight, awaken your super powers, and change your life against the will of heaven. The whole world was reveling, but I saw the remains of twelve dead civilizations floating in the universe. People who sell regrets will eventually dissipate within fourteen days to ten years, and there is no cure. If you speak a warning, it will be wiped out on the spot; if you spread it privately, civilization will die. My name is Chen Mo, and I am the only civilization fire adaptor on earth. At the beginning, I smashed the system panel that could be exchanged for 1.27 Million, and rushed against the carnival crowd to the man on the rooftop who wanted to die. Because I know that this is my only way to survive, and it is also the only way for all mankind to survive. But no one knows that I regret taking this savior for granted.
