The Rise of the Sect: It All Depends on the Sect Leader's Ruin.

As a time traveler, Lin Feng, a hard-working young man, didn't know which boss he had offended and gained a cheating system. Originally, Tianhu started with a time travel and system, but it turned into a business simulator. If you establish your own sect, you have to rely on yourself for everything, so forget it. Even the system's return of lost money must be calculated carefully and must be reasonable and compliant, otherwise the great rules of forced buying and selling will severely punish him. All of this made him work hard and fight. When the sect grew stronger and gained a foothold in the world, Lin Feng discovered that what I lacked was not resources or spiritual stones! What I lack is a reason to spend money.
