Longevity, starting from raising chickens

I'm very sorry, I'm going to Shanghai today, because the study task this time is relatively heavy, and there will be very little time for coding. I will try my best to code, but the number of words may be less than usual, and this situation will probably last until the 9th , I will go back on the 9th and try to restore the normal number of updates that day, at least 6000. I can’t guarantee if there are more. Thank you everyone for your support and understanding. Thank you! (End of chapter)
