System notification?

In the previous Goldfish Catching project, as soon as Chen Feng completed it, the system immediately notified him of a successful check-in. But now, the system was like a clay ox entering the sea, with no response at all.

Perhaps he needed to obtain the game token to successfully check-in. If that were the case, he should have taken a chance earlier.

Chen Feng seemed to have found a reasonable explanation, but his intuition told him that wasn't it.
