Eternal Landlord: I Grow Stronger by Collecting Rent

After transmigrating to another world, Lu Ming worked diligently for a hundred years and finally bought three houses. He thought he could lie flat, collect rent, and enjoy his remaining years in peace. But his body's vital energy couldn't withstand the ravages of time. It dwindled away, leaving him on death's door. Just as he was taking his final breaths, the Rent-to-Get-Strong System awakened! As long as he collects rent, he can extend his life, temper his body, attain enlightenment, defy the heavens, and grow stronger until he reaches the peak! From that day on, the world had its most domineering landlord. “Landlord! We agreed on two bloodstones a month. Why did you suddenly raise the rent?!” Faced with his tenants' questions, Lu Ming remained calm, his tone languid. “Things have changed. Now, you'll have to pay more.” “How can you raise the rent just like that?!” In a chaotic world spanning countless realms, everything brings suffering. Only collecting rent is eternal.
