There are no in isolation. Now that I have , my throat hurts like hell. I asked for a day off. My fever has not gone away today and I feel dizzy.

I apologize. I wrote the second chapter last night when I was in a feverish and comatose state. There may be typos and mistakes. Please forgive me, fellow battle brothers.

Wear a mask when going out, don't touch your eyes and nose with your hands, wash your hands when you come back, spray the soles of your glasses with alcohol, drink more water, exercise more and do less exercise.

If the fever subsides tomorrow, I will update the code as normal. Finally, I wish all the fighting brothers good health.
Chapter completed!
