After the Apocalyptic R&D Boss Failed, the Assistant Panicked

On the eve of the zombie virus outbreak, I retreated to the mountains and forests to live a farming life. But my assistant frantically called me begging me to come out and save the world. But I was too busy farming to pay attention to him. It turns out that in the last life, my assistant handed over the same virus antidote as mine. She was hailed across the country as a savior, yet she turned around and accused me of stealing her antidote formula. Netizens have criticized me for execution on the spot. The leader was furious and drove me out of the safe area. My boyfriend even took away my personal weapon, leaving me nowhere to survive among the zombies. In the end, I died tragically in the zombie's belly. What I never expected was that when I opened my eyes again, I went back to the week before I submitted the antidote.
