I'm Really Not a Loser.

Zhang Xiaomiao traveled from a philanthropic family to the home of a wealthy man in a powerful country. He posted a notice "Alleviating the poor and helping the needy" and began donating money for emergency relief, thus getting acquainted with some strange people. Some of them have space-time shuttles, some have ever-changing spells, and some have highly intelligent and fully automated libraries... Zhang Xiaomiao did not lose his family in the end, but made both his old and new families prosperous and happy.
