Lu Chaochao went through the book. He was transformed into a cannon fodder who was drowned at birth and whose identity was taken over by the heroine.

The heroine killed her relatives out of righteousness and reported that her adoptive mother and grandfather were collaborating with the enemy and treason, causing the whole family to be wiped out.

The heroine takes back her mother, escapes from her scumbag father, Jin Chan, and lives a beautiful life together. Only Lu Chaochao and his whole family are stepping stones.

Lu Chaochao looked at his mother who had been brainwashed for many years: “Mom, your beloved husband is waiting for the birth of a child outside the house.”

The love brain mother is awake! Lu Chaochao looked at his disabled elder brother and sighed: “Brother, you are being abused, you are so beautiful, strong and miserable! Fortunately, I can heal your leg!”

Turning around, the eldest brother hit three yuan in a row, trampling all the talents in the capital under his feet. “Second brother, what you believe is inhumane. Your best friend is Daddy Scumbag’s concubine! ”

“Third brother, you were deliberately raised to be useless. You are uneducated and have a gambling habit. In the end, you became a human pig.”

Lu Chaochao complained, realizing that the whole family had changed their fate against fate.

The scumbag was divorced, and the three brothers became the best among men! Even holding a milk bottle in her mouth, she is admired by the whole world!
