I Died Rich and Woke Up Gutting Fish in 1978, So I Made $125 Million in 15 Days

He went to sleep a wealthy man in a five-star hotel and woke up sixteen years old in a Kowloon fishing village in 1978, with nothing but a fish knife, a photographic memory, and the working knowledge of every financier who had been sleeping on the floors above him. Eleven weeks later a dying newspaper, a borrowed hundred and twenty thousand dollars and one very carefully written article had turned into a media empire, a securities house and a war with the British trading houses that owned Hong Kong. This is a rebirth and reincarnation story about business, revenge and the stock market, with an OP MC who never once uses a cheat he cannot explain, and it is a full novel recap in the style of our manhua and manhwa recaps. The Keswick family did not come to his party, and they are counting his shares right now, so tell me in the comments whether he should sell The Wharf or keep buying.
