Immortality Starts With Generosity Book 1

A lost soul from Earth transmigrates into a world of cultivation and finds himself in the body of a playboy noble who is wasting his life. Except Chen Haoran doesn't have any memories, can't let anyone know he's not the same person, and is immediately involved in a conspiracy with another powerful noble family involving the downfall of a prominent young genius. Luckily, he came to this world with a power: whatever he gives to someone as a gift he'll get it back 100 times better. His first target? His new wife, the former top young genius.
