[Travel + farming + system + space + not brainless + no male protagonist + not brainless] Traveled through time, Such a small chance happened to me, and I also traveled to the body of a 6-year-old baby. I had a poor family with no father or mother. There was only a worried elder brother, a poisonous second brother, an eldest sister who was sometimes irritable, and my weak body. Wang Zining roared up to the sky, he had just signed a big contract, a big order, and now he was able to take advantage of that girl, his best friend, and hoped that she would shed a few tears for him when she found out that he died. Wait, who is this person? Why does he look so much like his resentful best friend Zhang Xiaomin? She has also traveled through time. Now there is nothing left. Looking at two weak doll bodies, how can they make money? No, after meeting my best friend, I awakened a different world upgrade system, but other people's systems are very powerful, but my own needs to earn money to unlock all kinds of modern things, mobile phones, Internet, etc. What else can I do? I can only make money. I can only make money with my best friends and gradually unlock and improve my quality of life. Make money, support your family, change your family, However, there was a fire in the backyard, and his brother fell in love with his best friend. It seemed that his best friend was taking advantage of his brother's overlord. What to do? Nothing to do! Make money, support your family, and become a rich man!
