Born Into a Cultivator's Body, I Grew Strong by Reaping the Whole Cultivation World

In the real world, a young man dies suddenly after staying up all night playing Delta Force. His soul transmigrates to a cultivation world, into the womb of a member of a powerful cultivation clan. While still a fetus, he awakens the "Get Stronger by Earning Harvard Coins" System in his mental world. The System has unusual rules: whenever he obtains treasures such as cultivation techniques or pills in the real world, he receives an equal amount of Harvard Coins in the System.
