Reborn Rich (Manhwa) Vol. 4 (manga)

Leveraging his knowledge of future events, Dojun managed to turn a modest gift from his super-rich grandfather into the seeds of an investment empire. His ambition is limitless: He'll stop at nothing to build a company big enough to rival his grandfather's own gigantic Soonyang Group, and with so many scheming relatives lurking in the wings, his very survival may depend on it. As he puts the finishing touches on a high-stakes deal to create a new automotive giant, Dojun knows a much bigger struggle looms on the horizon.

The Korean economy collapsed in the 1990s, and simply weathering the storm won't be enough. With enough American dollars in hand, Dojun can turn the crisis into a massive opportunity!
