Black technology: starting from ten thousand times faster

I'm sick, I have a headache and a cough. I don't know if it's the mycoplasma pneumonia that has been so common recently. It's very uncomfortable.

The key is that I took the injection for two days. My headache seems to be worse today and I have to go to the hospital for a checkup tomorrow.

I really can't bear it anymore, so I have to take a leave.

Everyone, please take care of your health. (End of chapter)
