After Rebirth, the Vicious Elders Knelt Down One by One and Fell in Love with My Sister

In his last life, Jiang Han was miserable! When I was a sophomore in high school, both my parents died due to illness, and my uncle and third uncle coaxed me to take away my inheritance and divide it among them. From then on, I and my only sister were left alone, living in the uncle's and third uncle's homes respectively, and they lost contact with each other since then. After a few months of not having enough time to finish a meal, Jiang Han chose to drop out of school before even finishing his senior year of high school. After entering society, he suffered a lot of cold eyes and suffering because of his lack of education. When I was 28 years old, bad news suddenly fell from the sky - my only sister committed suicide! It turned out that my sister had been abused at the third uncle's house, so she suffered from depression at a young age, and was later sold by the third uncle like goods... In the end, my sister became severely depressed and committed suicide! Just when he went to seek revenge against his third uncle, he was hit by a large truck and died tragically on the street at the age of only 28! After opening my eyes, Jiang Han discovered that he had been reborn, to a time when his parents had just passed away and all the tragedies had not happened yet! Live a new life, Jiang Han is determined not to repeat the same mistakes again. He will make all those who harmed his sister in the previous life pay a heavy price. He will work hard to make a career so that his sister can live a good life. He will protect her for the rest of his life! But God played a huge joke on him. His biological sister who he grew up with has no blood relationship with him! What's even more outrageous is that his sister actually fell in love with him...
