Xu Zhiwei was reborn with the memories of his past life and returned to the day when his mother died due to nuclear radiation and returned with her relics. In her previous life, in order to repay the kindness of the Huo family, she gave up her studies, trapped in an arranged marriage, served her parents-in-law, and endured for half her life. However, she was rejected by her mother-in-law, despised by her daughter, and was eventually buried in the ruins of her old house. After her rebirth, she broke up with Huo Changting, cut off the entanglement with Qi Muxue's mother and daughter, inherited her mother's legacy, and went to the desert to devote herself to nuclear physics research. She relied on her talent to delve into the field and eventually became a pillar of the country, dedicating her life to the motherland. But when Huo Changting suddenly came to his senses, all he had left was a lifetime of regret, and he grew old all night in front of her grave, leaving only endless sorrow.
