Xiang Beifei wasn't worried about being suspected for taking Yuchi Shen's system reward, although he didn't know what the other's system task was. The higher the level of the system reward, the longer it definitely took to complete.
He had only completed one system task, which might not be enough for Yuchi Shen to receive a reward immediately. It probably would accumulate over some time, possibly taking several days, or even several months to receive.
During this period, many changes could occur, and many people would be involved in his task, making it less likely for Yuchi Shen to suspect him.
Even if some small rewards could be obtained immediately, Xiang Beifei also needed to alert Xiaohei, reminding it to pick the timing and disguise itself when retrieving the parcel.
