Chen Jianjun wakes up to find himself a twelve-year-old boy in a courtyard house.
His father, Chen Youde, is a hard-drinking brute who beats and berates his wife and children at the drop of a hat. His mother, Li Xiulan, works as a temporary laborer at the steel mill, but even working herself to the bone, she can't feed the family. His little sister, Chen Qiaoqiao, is so hungry she follows him around collecting scraps, and Banggeng even steals the candy from her hands.
Silly Zhu takes their side, Yi Zhonghai lectures them, Jia Zhangshi throws tantrums, and Qin Huairu plays the victim.
Everyone thinks the Chen family is easy to bully.
That is, until Chen Jianjun grips a kitchen knife and a voice rings out in his mind:
[Ding! Today's sign-in is successful. You have received a portable supermarket space.]
From that day on, Chen Jianjun stops putting up with it.
His sister wants candy? He gives her some.
His mother wants a peaceful life? He protects her.
Anyone who dares bully the Chen family will learn that even a young boy can turn the entire courtyard upside down when he gets serious.
Sign in by the river and receive premium fishing bait.
Sign in at the steel mill and gain expert-level lathe skills.
Sign in at the laboratory and receive radio blueprints.
From fishing for money to assembling bicycles; from making radios to building cars, televisions, cameras, and projectors.
Step by step, Chen Jianjun leads his family to a life with enough food and warm clothes, while leaving everyone who looked down on him further and further behind.
In this life, he builds his fortune through sign-ins, protects his sister and mother, and lives life to the fullest.
What did you write? This protagonist is probably a waste in modern times. Modern people know what is good for themselves. In those days, as long as you were reasonable, it would be no big deal if you were beaten.
The protagonist is a loser and is so scary that he wouldn't even dare to hit anyone!
