Take the Landlord of the Shopping Mall and Do Whatever You Want and Be Happy

[Alternate history + multiple female protagonists + stunning sister-in-law + system shopping mall + brainless coolness] (Changgen, the widow doesn't want you, the sister-in-law does) My name is Niu Changgen, a powerful cow, what you think of as Changgen. Because of his luxury, he went to the second floor of the Foot Washing City. As a result, he died suddenly and traveled to an imaginary ancient world of troubled times and the desolate years, and awakened the system mall. As long as you recharge gold and silver, you can purchase any modern item. So I bought guns while making money, and used the guns I bought to make money. After my unremitting efforts, I finally lived a happy life in ancient times with a group of wives and concubines, no one dared to mess with me, and thousands of acres of fertile land.
