After Reincarnation, I Start from Scratch!

Zhang Lei has an ordinary name, ordinary appearance, and ordinary origin. He is just a hard-working young man struggling at the bottom of society. However, Zhang Lei accidentally reincarnated into another world in order to save a woman who committed suicide by jumping into a river. What? The savior raised two daughters alone? Zhang Lei: "The kindness of a drop of water should be repaid with a spring of water! Uncle Liu, from now on you are my biological father!" Uncle Zhang Liu gritted his teeth: "You brat, you are repaying a favor with a grudge!" Zhang Tiantian: "Dad, Zhang Lei is really outstanding." Zhang Sisi: "You scumbag! Let go of my sister and come at me if you can!" Song Yutang: "Husband, you are so awesome." Yu Xinyi: "Sister Tiantian wouldn't be angry if she knew you came to see me, right?" Xu Zhengxi: "I am the one who brought you into this world. No matter what you ask for, I will agree to it!" Zhang Lei looked up to the sky and sighed: "I'm so tired." In this way, Zhang Lei relied on his past life memories to reach the top of his life step by step from scratch! This novel and its characters are purely fictitious.
