The Great Genetic Era

On the 18th line in the northwest, there is a red code at home, and the school on the side of the two children is in a hurry. It just so happened that there was also an epidemic in the county seat, and the kind of people who kept their feet on the ground from morning to night and kept their mobile phones on.

At present, the nucleic acid of the whole family is negative, and the red code is also negative.

good luck.

Please take a day off, sorry!
