Fortunate Young Gentleman

A 21st century master's degree holder, his soul traveled to ancient times.
No ring, no system, no white-bearded grandfather, no memory of this world...
My God, I have nothing at the beginning, I don't even know who I am, how can I play this?
Hungry and depressed, Tang Ning couldn't help but raise his head and raised his middle finger: "Thief..."
Something flew from the sky and hit his forehead.
Holding a big red hydrangea, before fainting, he only wanted to ask: "Who the hell stuffed a stone into the hydrangea!"
When he opened his eyes again...
A maid smiled like a flower: "Sir, the young lady invites you!"
A woman with beautiful eyebrows and eyes: "My husband, I am polite!"
