Lin Sizhi handed over a 1000-minute voucher: "Very good, this is a reward for your cleverness.
"Next, all you have to do is give me a thumbs-up when you leave the venue."
Zhao Duo happily accepted the voucher, but was somewhat puzzled: "But the checking machine refreshes only once an hour; how can you be sure I gave you a thumbs-up?
"Are you going to use a broadcast to verify? But in that case, the like would be used up."
Lin Sizhi explained: "Of course, there's no way to distinguish, and I won't waste extra effort thinking about those issues.
"As long as in three meetings within an hour, I haven't received 3 likes, it means someone didn't keep their promise.
"In that case, I will no longer invite the above three people, and instead, match with three new players.
"Until the hour when I receive all 3 likes, then I will continuously invite these three players in sequence and maintain this cooperative relationship until the game ends."
