A Life-or-Death Red Packet

One day, every student's phone suddenly gained a new contact named the Fate Controller. He sent an invitation to join a red envelope group, and the students found themselves unable to refuse. He started sending out red envelopes in the group while issuing all kinds of missions. As everyone completed the missions to grab the red envelopes, the world was changing...

When dead family members appear at home.

When the law ceases to be just.

When hellish scenes appear in reality.

How should humanity survive?

And does any of this have something to do with you?
