Reborn in the courtyard house of 1965, Jia Dongxu clenched his fists. In his last life, he was useless for half his life, his wife and children were humiliated, and he died with hatred. When he was recovering from a broken leg, he looked at the haggard Qin Huairu and the starving children, his eyes icy. Xu Damao's evil deeds, Silly Zhu's hypocrisy, the elders' schemes... In this life, he holds both grudges and gratitude. The molten iron in the steel rolling mill tempers the bones, and the muddy water in the courtyard strengthens the mind. He wants to protect his family, seek justice, and make the bullies pay back a hundredfold!
