When the Weirdness Comes, I Can See the Gaps in the Rules

On the first night of the rule, all shopping malls in Linjiang City lost power at the same time. Only three sentences were repeated on the radio: don't look up, don't answer strangers' names, and don't step out of the yellow tiles. Shen Zhixing took his sister and hid in an underground supermarket, and found that three rules conflicted with each other: the broadcast asked everyone to keep quiet, but the exit instructions required shouting their names; those who could not raise their heads must see the countdown above their heads; those who could not walk out of the yellow floor tiles, there was only a red line under their feet. He grabbed the gap and survived with his sister. But the next day, a new line was added to the city's rules announcement: "Those who find gaps will be dealt with first." From that day on, Shen Zhixing could only avoid the rules while finding out the source of the rules. Every time a person is saved, his position will be exposed; every time a rule is dismantled, a more ruthless rule will appear in the city.
