After the Power Outage in the ICU, I Watched the Elderly Suffocate to Death

In my last life, there was a power outage in the ICU, and I worked very hard to save 200 elderly people. When I woke up, my daughter falsely accused me of deliberately cutting off the power, causing the elderly people to suffocate to death. The angry family members beat me to death. If I live my life again, I will never let tragedy happen again.
